This property is King County Parcel #152104- 9022, a 5.97 acre site located at the north end of North Lake, in the NW quarter of Section 15, Township 21, Range 4. DOCUMENTS REVIEWED The following documents and resource information websites were reviewed by Perteet prior to the site visit: • King County Online Property Information (htti2-//www.kingcounty.gov/operations/GISIMaps/!MAP.aspx), accessed May 1 1, 2015. • City of Federal Way critical area reap (hnp://www.cLtyoffedtmlway.com), accessed on May 11, 2015. • USDA Web Soil Survey (http://websoilsurvey.nres.usda.gav/al2plHomePage.htm), accessed May 11, 2013. ■ U.S. Department of the Interior, Fish and Wildlife Service. National Wetland Inventory (NWI), Wetlands Mapper(http:/lwww.fws.,Fovlwetlands/index,fitml), accessed May, 11, 2015. Washington State Department of Fish and Wildlife (WDFW) Salmonscape database. (http:llwdfw.wa.govlmappinglsalmonscape/index.htm]), accessed May 11, 2015. • Washington State Department of Natural Resources (WDNR) Forest Practices Application Review System (FPARS) Viewer (http:llfortress.wa.gov/dnr/app l lfpars/viewer.htm), accessed May 11, 2015. • Wetland & Stream Delineation With Standard Buffer Width Determination, Barcelo Homes Site Development, prepared by EnCo Environmental Corporation, dated December 17, 2014. Resource information is consistent with information provided, and also, reviewed in the EnCo Report. Primarily, resource information identifies a large wetland complex on the west side of the property associated with the north end of North Lake. Barcelo Homes Property — Critical Areas Review Page I Memorandum SITE VISIT N Perteet On May 6, 2015, Perteet Inc. conducted a site visit of the subject property; in attendance were Jonathan Kemp, Professional Wetland Scientist of EnCo; Jason Walker, Professional Wetland Scientist with Perteet; and Becky Chapin, Associate Planner with the City of Federal Way. The purpose of this visit was to conduct a critical areas review of the property based on the resource documents and reports prepared for this area. During this site visit we examined the entire property and observed all delineated wetland boundaries. Perteet examined both wetland and upland areas on the property. This involved locating most of the wetland flags and the soil pits that EnCo located in September 2014 and described in their December 2014 report. We observed indictors of wetland vegetation, hydrology, and soils in Wetlands A, B, C, D and E. REVIEW COMMENTS Listed below are our findings along with requested actions in bold type: Perteet agrees with determinations and delineations as flagged and mapped for Wetlands A, B, C and D, and Stream A. Wetland E however was observed to be a component of Wetland D, exhibiting bog plant species (e.g. labrador tea, Ledum groenlandicum), but is not an easily distinguishable wetland unit based on HGM class. Wetland units can be separated by HGM class under Ecology wetland rating guidance by identifying abrupt changes in hydrologic support. Although, to delineate one wetland unit within another can be difficult to determine with substantial justification unless the changes in hydrology are abrupt or otherwise apparent or if the change in HGM class can be otherwise determined through an empirical analysis of groundwater with detailed monitoring. However, the Federal Way code does not utilize the Ecology Wetland Rating System (currently, ratings are based on FWRC 19.175.020 and FWRC 15.10.250 for shorelines) and the requirements for segregating contiguous wetland units are not defined in the current code, and there is understood to be no precedent for doing so under the FWRC. The current code is written to assume the higher wetland category if the wetland "contains the presence" of listed ecological functions (i.e. a bog). The presence of the bog component of Wetland E within Wetland D therefore meets the criteria under the FWRC for the entire wetland to be a Category I. A new Critical Area Code is also scheduled for City Council Second Reading June 16th, with a possible effective date of June 30, 2015. Since this is a City Council decision, dates are understood to be subject to change. Wetlands within the Shoreline jurisdiction (i.e. Wetland D/E) will however remain regulated under FWRC 15.10.250. Rate all wetlands A, B, and C under the 2014 Wetland Rating System for Western Washington if the application will be vested after the new code is in effect. Regardless of vesting to the current or new code for Regulated Wetlands, Wetland D/E will be considered to have a bog component and is to be rated according to the Shoreline section of the FWRC 15.10.250. 2. A question was raised by the City during our field visit whether Wetlands A, B, and C meet recognized criteria to be considered as a wetland mosaic. Wetland mosaics are defined in the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). In general, wetland mosaics Barcelo Homes Property — Critical Areas Review Page 2 Memorandum are areas of interspersed wetland and upland in a mosaic pattern, and wetlands in this instance are usually too closely associated to be easily delineated individually. The wetlands in question (Wetlands A, B, and C) are individually distinguishable, not closely associated pursuant to the regulatory guidance, and do not meet the "mosaic" definition. Perteet concurs with the boundaries of Wetlands A, B, and C. No further action is necessary. 3. A depressional landform northwest of Wetland C and B was identified in the field that appeared to have indicators of hydric soil, some indicators of hydrology, and some wetland and upland vegetation. Subsequent information has been provided by Eco on May 11, 2015 to document a dominance/prevalence of upland vegetation in this feature and all not all criteria are met for a positive wetland determination. No further action is necessary 4. No impacts to critical areas are approved at this time. In general, a mitigation plan consistent with the FWRC is required for any impacts and has not been provided or evaluated for code consistency for this preliminary review. Submit a complete mitigation plan if impacts are proposed with the formal plat submittal.

That is how it reads to me, as we have discussed. Regardless of any Ecology opinion, cities can opt to have ordinances that are more protective than State or Federal codes and guidance due to the uniqueness of their communities, and I will support the City to maintain this authority if that is the correct administrative interpretation.

Per the attached email, it appears Mr. Kemp has been in communication with Ecology regarding the dual rating of Wetland D&E. Also, below is the email I sent this morning responding to an email I received last week. I don't believe Ecology can make a determination in the dual rating as our shoreline wetland code has its own wetland categories and does not utilize the Ecology rating system. Do you see a benefit of a site visit from Ecology?

The shoreline critical areas code does not utilize Ecology rating system for wetlands. 15.10.250 Wetland categories and standard buffers. (1) Wetlands are classified into the following categories: (a) Category I wetlands meet one of the following criteria: (i) Contain the presence of species or documented habitat recognized by state or federal agencies as endangered, threatened, or potentially extirpated plant, fish, or animal species; or (ii) Contain the presence of plant associations of infrequent occurrence, irreplaceable ecological functions, or exceptional local significance including but not limited to estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange areas, significant habitat, or unique educational sites; or (iii) Have three or more wetland classes, one of which is open water. (b) Category II wetlands are greater than 2,500 square feet in area, do not exhibit the characteristics of Category I wetlands, and meet one of the following criteria: (i) Are contiguous with water bodies or tributaries to water bodies which under normal circumstances contain or support a fish population, including streams where flow is intermittent; or (ii) Are greater than one acre in size in their entirety; or (iii) Are less than or equal to one acre in size in their entirety and have two or more wetland classes, with neither class dominated by nonnative invasive species. (c) Category III wetlands are greater than 2,500 square feet in area and do not exhibit those characteristics of Category I or II wetlands. (2) Standard buffer widths for regulated wetlands are established as follows: (a) Category I wetlands shall have a standard buffer width of 200 feet. (b) Category II wetlands shall have a standard buffer width of 100 feet. (c) Category III wetlands shall have a standard buffer width of 50 feet for wetlands that are greater than 10,000 square feet in area, and shall have a standard buffer width of 25 feet for wetlands that are between 2,500 to 10,000 square feet in area. Per the code above the city, with the help of our consultant, Perteet, has concluded that Wetland D/E would both meet the criteria for a Category I wetland with the standard 200 foot buffer. If you believe FWRC 15.10.250 allows for dual rating, please let me know how you have come to that conclusion and I can discuss it further with my Planning Manager, Isaac Conlen. I did receive your email today as well. Your request for reports or studies pertaining to North Lake and it's contiguous wetlands and the bog will have to be addressed as a records request, I'm not sure what we have on file and it will take some time to produce all the records.

Becky Chapin From: Jonathan Kemp <jkemp@encoec.com> Sent: Tuesday, June 02, 2015 9:08 AM To: Becky Chapin Subject: EnCo and Barcelo Homes Good Morning Becky: I have consulted with Ecology regarding if the dual rating of Wetland D/E will apply for the Barcelo Federal Way project. The interpretation from Ecology is based on my rough calculations as to the size of Wetland D and the size of the bog component within the wetland (Wetland E). Based upon Ecology's in-house review, a "dual rating" of a wetland applies when a bog component is small (defined as less than 10% of the entire wetland being rated). My rough calculations for the size of Wetland D/E I used in my report may be too small if the wetland complex includes North Lake and all of its contiguous wetland. Does the City have any reports or studies on file pertaining to North Lake and its' contiguous wetlands and the bog. I need to determine if Wetland D includes the land mass of North Lake and its' open water plus its' surrounding wetlands that are contiguous to the lake. If Wetland D includes all of North Lake and its' surrounding wetland than the bog component of the entire wetland may be less than 10 percent. If this is the case that we would be able to use the dual rating of the wetland. Please provide an answer to this as soon as you can. I would like to schedule a site visit by a specialist from Ecology to determine if the dual rating will apply to this wetland complex. Jonathan Kemp, Principe EnCo Environmental Corporation P. Q.

Becky Chapin From: Jonathan Kemp <jkemp@encoec.com> Sent: Tuesday, June 02, 2015 10:53 AM To: Becky Chapin Subject: RE: Barcelo Homes Critical Areas Review Memo Hello Becky: I do conclude FWRC 15.10.250 allows for a dual rating as explained below: FWRC 15.10.250 Wetlands Categories and Standard Buffers (1) (a) (ii) states "Contain the presence of plant associations of infrequent occurrence, irreplaceable ecological functions, or exceptional local significance including but not limited to estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange areas, significant habitat, or unique educational sites" The FWRC code does not clearly define what the word "contain" means. One can interpret "contain" to mean "totally contain" while another can interpret the word to mean "partially contain". The definition of Contain means to hold, carry, accommodate, or seat. It does not necessarily mean to "totally contain" and so "partially contain" should be able to carry the same weight. This being said then it is possible that the smaller bog component of the wetland complex can be treated separately from the remaining non -bog portion. The bog (Wetland E) is partially contained in the total containment of Wetland D. This being the case then the buffer for the bog component (Category I Wetland E) would carry a 200 foot wide buffer while the forested portion of the wetland (Category II Wetland D) would carry a 100 foot wide buffer. Wetland D would be a FWRC Category II wetland because it does not exhibit the characteristics of Category I wetland and does meet 15.10.250 (1) (b) (i), & (ii). I conclude that best and fairest way to accommodate this unique situation would be to allow for a dual rating of the wetland because there are clearly two very distinct habitats involved. also conclude that a 100 foot wide buffer from the edge of Wetland D will totally protect the ecological functions and values of the entire wetland complex because of the steep side slopes next to the wetland edge; due to the heavily forested buffer that exists east of the wetland; due to the fact that previous developments already exist in close proximity to this wetland in the area; and that there are remnants of a previous development on this site (stone wall, cistern, well, and foundations) of a previously existing home in very close proximity to the wetland. Please discuss my conclusion with your Planning Manager, Isaac Conlen. Jonathan Kemp From: Becky Chapin [ma iIto: Becky.

Becky Chapin From: Jonathan Kemp <jkemp@encoec.com> Sent: Friday, May 29, 2015 5:01 PM To: Becky Chapin Subject: RE: Barcelo Homes Critical Areas Review Memo Hi Becky: In Jason's memorandum (Item 1, Page 2) 1 am not clear as to why the Federal Way Shoreline Code (FWRC 19.175.020 and FWRC 15.10.250) does not utilize the Ecology Rating System and supersedes the Federal Way Critical Area (Wetland) Code (Chapter 15.10) when deciding when to set buffers and allow the "dual rating" procedure to separate the bog part of the Wetland E from the forested (not a bog) part of the wetland (Wetland D) on this site. Please explain this and provide the citation in the Federal Way Code where it clearly states that "Federal Way Code does not utilize the Ecology Wetland Rating System and that ratings are based on FWRC 19.175.020 and FWRC 15.10.250". Also please provide the citation which explains why the Federal Way Wetland Code (Critical Areas - Chapter 15.10) does not apply to Wetland D / Wetland E. Also in reference to Jason's memorandum (Item 1, Page 2) please provide the Code citation that clarifies: "The current code is written to assume the higher wetland category if the wetland contains the presence of listed ecological function i.e. a bog. I would like an explanation as to why this assumption has turned into a conclusion to not allow a "dual rating" of the wetland complex associated with North Lake.

Box 1733 Auburn WA 98071 RE: Test Plot 13 Letter Report Barcelo Homes Site Development 32605 39th Avenue South, Federal Way, King County, WA 98001 Current Land Use: Forest Proposed Use: Residential Development — SFD Dear Ms. Maksimachuk: May 11, 2015 EnCo Environmental Corporation (EnCo) has completed the additional test plot (Test Plot 13) that was requested for completion by Mr. Jason Walker, PLA, of Perteet Engineers during our site visit that was held on May 6, 2015. The site visit was held in concert with Ms. Becky Chapin, Associate Planner, of the City of Federal Way. PURPOSE The purpose for performing the work was to determine if a small depression located about 75 feet north of northern edge of Wetland C was wetland or upland. SCOPE OF WORK 1. Established one (1) test plot in the small depression as shown on FIGURE5 — WETLAND & STREAM DELINEATION (ATTACHED). The test plot was hand - sketched onto the existing figure. 2. Collected and evaluated data for topographic features, soil characteristics, types of vegetation, surface and near surface hydrology, habitat, and observed animal and plant species in the test plot. 3. Determined whether or not the test plot was a wetland according to the three established wetland criteria; hydric soil, wetland hydrology, and dominant hydrophytic vegetation according to jurisdictional government agency methodology. 4. Prepared a hand sketch (not to scale) depicting the approximate location of the test plot over a professionally land surveyed diagram (FIGURE 5). 5. Prepared a photo log (ATTACHED) 6. Completed a wetland determination field data form. 7. Prepared this letter report summarizing the findings of the study. Site Assessment • Wetland • Remediation • Habitat 1 RESULT The presence or absence of a wetland in the test plot was verified by collecting scientific data in the field. Wetlands are defined by the USACOE and ECOLOGY as having conditions that meet the technical requirements for being a wetland according to the established criteria for wetland hydrology, hydric soil, and dominant hydrophytic vegetation. A summary of the rationale for making the upland determination for the test plot is listed in TABLE 1. More detailed information and data pertaining to the wetland / upland determination for the test plot is presented on the field data form (ATTACHED). TABLE 1 WETLAND / UPLAND DETERMINATION RATIONALE Plot Hydric Soil Indicators Dominant Hydrophytic Wetland Wetland Jurisdictional # in Upper Part (<12") Vegetation Hydrology 1 Upland Yes No No Depleted Matrix 20% (50/20 Rule) 1 Secondary Upland No 10YR,2,2 Beaked Hazelnut - FACU Water Stained 13 10YR, 3,2 Salmonberry - FAC Leaves No Redox Indian Plum - FACU Gravely Silt Loam Trailing Blackberry - FACU (Native) English Ivy - FACU CONCLUSION Test Plot 13 was determined not to be a wetland. CONDITIONS This report is presented without warranty, express or implied, except that the services associated with this letter report are rendered by EnCo in good faith and according to the standards generally practiced by professional wetland scientists in the area of wetland and stream evaluation. This critical area determination for the test plot was limited to the portions of the project as defined in this report and as directed by the reviewing consultant (Perteet). The work did not include performing a professional land survey to locate the test plot. Sincerely, Jonathan M. Kemp President, EnCo Environmental Corporation, P.W.S.

Box 1733 Auburn WA 98071 RE: Wetland & Stream Delineation Report Addendum # 1 Barcelo Homes Site Development 32605 39th Avenue South, Federal Way, King County WA 98001 Current Land Use: Forest Proposed Use: Residential Development — SFD Dear Ms. Maksimachuk: The City of Federal has requested that EnCo Environmental Corporation (EnCo) prepare an addendum to the wetland delineation report that was completed last fall. This addendum supersedes the EnCo Wetland & Stream Delineation with Standard Buffer Width Determination, dated December 17, 2014. 1.0 PURPOSE The purpose for performing this addendum is to update information related to the final buffer width of Wetland D, the incorporation of Wetland E as a "bog component" of Wetland D, the final boundaries and buffers of Wetlands A, B & C, and the final result of the wetland assessment of Test Plot 13. 2.0 BACKGROUND A wetland and stream delineation was performed on the project site by EnCo as documented in the report dated December 17, 2014. Due to the complexity of the critical areas and regulatory buffers of wetlands associated with shorelines and wetlands not associated with shorelines, the City of Federal required that the EnCo wetland and stream delineation report be reviewed by their third party consultant (Perteet, Inc.). On May 6, 2015, Perteet Inc. conducted a site visit of the project site as part of this review. In attendance were Jonathan Kemp, Professional Wetland Scientist of EnCo; Jason Walker, Professional Wetland Scientist with Perteet; and Becky Chapin, Associate Planner with the City of Federal Way. The purpose of this visit was to conduct a critical areas review of the property based on the EnCo report, resource documents, and other reports prepared for this area. The review also included interpretation of jurisdictional critical area code and shoreline regulations in relation to wetland buffers associated with shorelines. Site Assessment • Wetland • Remediation • Habitat 3.0 DISCUSSION 3.1 Wetlands D & E Based on that review and after several follow up discussions with the City of Federal Way Planning Department and wetland and shoreline staff at the Washington Department of Ecology (ECOLOGY) it was concluded that the Federal Way shoreline regulations does not have language to utilize the Ecology Wetland Rating System for Western Washington for wetlands associated with shorelines. At this point in time wetland categories associated with shorelines are based solely on FWRC 19.175.020 and FWRC 15.10.250. These two shoreline codes do not allow for a "dual rating" of a wetland that has a Category I bog component incorporated within a Category II or III forested or scrub/shrub wetland. For this reason the presence of the identified bog component, identified as Wetland E in the EnCo wetland delineation is now mapped as part of Wetland D and must be rated as a Category I wetland with a 200 foot wide standard shoreline wetland buffer. Wetland E is now identified as a "bog component" of Wetland D as shown on the attached updated wetland exhibit (FIGURE 5 — 2014 (Amended 10.12.15) and in TABLE 11 — WETAND & BUFFER CHARACTERISTICS for Wetland D. 3.2 Wetlands A, B & C A question was raised by the City of Federal Way whether Wetlands A, B, and C meet the recognized criteria to be considered as a wetland mosaic. Wetland mosaics are defined in the 2010 Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Western Mountains, Valleys, and Coast Region (Version 2.0). In general, wetland mosaics are areas of interspersed wetland and upland that lay over the landscape in a mosaic pattern and are too closely associated to be easily delineated individually. The wetlands in question (Wetlands A, B, and C) are individually distinguishable, not closely associated pursuant to the regulatory guidance, and do not meet the "mosaic" definition. Perteet concurred with the boundaries, ratings, and buffers of Wetlands A, B, and C as presented in the EnCo report. 3.3 Depression Landform Located North of Wetland C As part of the wetland review process Perteet Inc. requested EnCo to assess a depressional landform that is located about 75 feet north of northern edge of Wetland C. One test plot was assessed (Test Plot 13) by EnCo on May 6, 2015 (FIGURE 5 — 2014 (Amended 10.12.15). This test plot was determined not to be a wetland as presented in the EnCo report dated May 11, 2015 (Attachment). This conclusion was supported by Perteet, Inc. in their Memorandum submitted to the City of Federal way, dated May 21, 2015. 4.0 CONCLUSIONS 1. Wetland D is a Category I wetland with a 200 foot wide standard shoreline wetland buffer. Wetland E is now identified as a "bog component" of Wetland D.

The site visit was held in concert with Ms. Becky Chapin, Associate Planner, of the City of Federal Way. PURPOSE The purpose for performing the work was to determine if a small depression located about 75 feet north of northern edge of Wetland C was wetland or upland. SCOPE OF WORK 1. Established one (1) test plot in the small depression as shown on FIGURE5 — WETLAND & STREAM DELINEATION (ATTACHED). The test plot was hand - sketched onto the existing figure. 2. Collected and evaluated data for topographic features, soil characteristics, types of vegetation, surface and near surface hydrology, habitat, and observed animal and plant species in the test plot. 3. Determined whether or not the test plot was a wetland according to the three established wetland criteria; hydric soil, wetland hydrology, and dominant hydrophytic vegetation according to jurisdictional government agency methodology. 4. Prepared a hand sketch (not to scale) depicting the approximate location of the test plot over a professionally land surveyed diagram (FIGURE 5). 5. Prepared a photo log (ATTACHED) 6. Completed a wetland determination field data form. 7. Prepared this letter report summarizing the findings of the study. Site Assessment • Wetland a Remediation e Habitat 1 RESULT The presence or absence of a wetland in the test plot was verified by collecting scientific data in the field. Wetlands are defined by the USACOE and ECOLOGY as having conditions that meet the technical requirements for being a wetland according to the established criteria for wetland hydrology, hydric soil, and dominant hydrophytic vegetation. A summary of the rationale for making the upland determination for the test plot is listed in TABLE 1. More detailed information and data pertaining to the wetland / upland determination for the test plot is presented on the field data form (ATTACHED).

CONDITIONS This report is presented without warranty, express or implied, except that the services associated with this letter report are rendered by EnCo in good faith and according to the standards generally practiced by professional wetland scientists in the area of wetland and stream evaluation. This critical area determination for the test plot was limited to the portions of the project as defined in this report and as directed by the reviewing consultant (Perteet). The work did not include performing a professional land survey to locate the test plot. Sincerely, Jonathan M. Kemp President, EnCo Environmental Corporation, P.W.S.

Construction of a single family residence is depicted in very close proximity to Wetlands B and C, both of which are under 2,500 square feet and understood to not be regulated (or acknowledged) under the code. The proposed building footprint on Lot 5 is shown within a few feet of the wetland boundaries of these features, and impacts to the wetlands appear likely due to the very close proximity of the proposed construction and due to probable grading impacts that are likely to be necessary to develop the lot, although grading is not shown in this preliminary site plan. Ecology will regulate these features, and the Corps of Engineers may also. It is therefore strongly advised that the applicant consult with Ecology (understood to be a party of record on this project) regarding the proposed construction activity on Lot 5. The City may consider a condition that correspondence from Ecology be provided to the City by the applicant to indicate that Lot 5 is buildable prior to conducting any land disturbance (or issuing building permit) on this lot. 3. Wetland A and its buffer will need a separate critical area protection tract. The City concurs with Jason's comments, the wetland/stream delineation and associated buffers are hereby approved. Please note: the City has yet to issue the final SEPA Determination of Nonsignifcance (DNS); waiting on resubmittal of the short plat drawings to see all potential impacts to the environment before issuing the DNS. It is likely that we will issue a mitigated DNS (MDNS) which includes conditions to set aside Wetland A and buffer into a tract, as mentioned above, and provide split rail fencing and signs. More information regarding the MDNS will follow at a later date. The next step will be for the city to provide a critical areas letter to Public Health. It is worth noting that the City does not have issues with the location of the septic system drain fields on Lot 5 in regards to Wetland B and C since they are not regulated by the City, however, you may need to verify with Ecology before proceeding with septic approval. Please let me know if you have any additional questions.

I was curious if you see any issues with the septic drain field locations. Before the applicant can get septic approval, King County Public Health has asked that the City provide a letter stating we have no objections to the location of the drain fields with regards to any critical area. I don't believe there are any issues, but I wanted to check with you before I issue the letter.

Questions for Wetland Buffer Enhancement Plan and Wetland Mitigation Plan (Barcelo Development - Federal Way 39tn) August 3, 2015 I will need to know what other agencies will be involved in the decision process besides the City of Federal Way; i.e. Ecology, Tribes, DNR, ACOE, Public Notice, Others? 2. 1 would also like to know what roles to these agencies or persons will have on the proposed action to fill these wetlands in completely? 3. What choices do we have to do the wetland mitigation for Wetlands B & C? I.E. do we have to create mitigated wetlands with the required ratios ON -SITE (on the project site parcels) or do we have an OFF -SITE option for the wetland mitigation (i.e. a local wetland bank)? 4. What is needed for wetland mitigation (creation) and I understand what ratios are needed for the wetland impacts. 5. Can we provide enhancements to the Shoreline Wetland Buffer (as required by Code) of Wetland D AND can we provide enhancements to Wetland D on the project site to help with the process of approving a proposed reduction of 100 feet of buffer for Shoreline Wetland D? (i.e. we are going to propose a buffer reduction of 50 Percent for the entire stretch of Shoreline Wetland D across the site). 6. Can we use the 15' building setback from the 100 foot wide buffer for plantings or edge opacity enhancement into the 100 foot wide buffer? 7. Can we install a wood rail fence or do we need a 6 foot solid fence to protect the buffer? 8. Will irrigation be required for plantings? 9. Can irrigation water be plumbed into the development and use City Water with a meter? 10. Can we use the existing open well in Wetland D with a pump for irrigation of the plants? 11. Existing Shrubs: The shrub layer is dominated by Salal (Gaultheria shallon), Indium Plum (Oemleria cerasiformis), and Beaked Hazelnut (Cornus sericea) 12.Other Shrubs to Plant: Vine maple, orange honeysuckle, service berry, ocean spray, red flowering current, salmon berry, thimble berry, gooseberry, nootka rose, wild clustered rose, red elderberry, snowberry, 13. Existing Herbs: The herbaceous layer is dominated by Sword Fern (Polystichum munitum), Trailing Blackberry (Rubus ursinus), Stinging Nettle (Urtica dioica), and Sweet Scented Bedstraw (Galium triflorum). Moss coverage ranges from about 30 percent to about 80 percent. 14. Other Herbs to Plant: Western Bracken Fern, Licorice Fern, Deer Fern, Slender Foot Sedge, Dewey's Sedge, Lady Fern, Henderson's sedge, large -leafed avens, 15. Existing Trees: The buffer area is dominated in the tree strata by: Douglas Fir (55); Red Alder (8); Big Leaf Maple (6); Black Cottonwood (3); Western Red Cedar (2); Madrona (2); Bitter Cherry (1); Scouler/Pacific Willow in Wetland (1); Pacific Crabapple (1). Thin out lower branches and remove stunted trees and re -plant. 16.Other Trees to Plant: Western Hemlock, Oregon Ash, Shore Pine, Paper Birch, Western Flowering Dogwood, Buckhorn cascara, TABLE Habitat Features Federal Way Ideas Feature Diameter Placement Units in Units in Length Characteristics Enhanced Wetland D Width Shape Wetland D 1 Height _ _ Other Buffer_ Bat Box _ Possible - _— Roost Boxes_ Possible Songbird Chickadee Woodpecker Titmice Screech Owl i Nest or Bird House Possible Wildlife Comment Box Possible Wildlife Observation 6"1 Note Taking 7"W Suggestions for Improvement 8"h Soil Embankment Possible at edge 22' to 50'1 4'w 1.5'h Entrance hole near bottom Ventilation holes if placed in sun Mounted about10 feet high Mount on plastic or metal pole Install in concrete base 1-[1111CU IVICLQ1 QUA On Metal Pedestal In Secure Area Lock & Key Access Note Cards Writina Pen Remove Roots Remove Rocks Add Sinuosity Variable Side Slopes Variable Surface Add Sinuosity 2 to 1 Side Slopes - van >2' Wide Top Surface Certified Weed Free Soi Jute Underlayment TABLE Habitat Features Federal Way Ideas Feature Diameter Placement Units In Units in Length Characteristics Enhanced Wetland D Width Shape Wetland D Height Other Buffer Snag - Created Pseudotsuga menziesii Douglas Fir Thuja piicata Western Red Cedar Snag-- Converted — Live Possible >15"d Stand Vertical to 20oOff Vertical >2O'h 100 - 200 Cut Top or Jagged >3" Diameter Top Branches 3' to 5' Long Top Branches > 2 Branchlets per Branches > 2 Branches per Snag Branches 3 to 5' from Top If Artificial, No Dowels Drill Holes in Tree for Branch Branches Facing N to E Leave Bark on Tree No Root Ball in Ground Dig a 6' Deep Hole in Earth 3' Radius Soil Mound — 1.5'h Soil Mount > 'I'Above Stand Water Compact Soil at Base of Snag Drill two 2"d cavities, >8' up Cavities Facing N to E.

December 17, 2014 FIELD WORK DATES: September 4, 5, 2014 1.0 EXECUTIVE SUMMARY On September 4 and 4, 2014, EnCo Environmental Corporation (EnCo) conducted a Routine Level Wetland and Stream Delineation for the presence and extent of jurisdictional wetlands and streams on the above referenced property, herein known as the project site. The project site is defined in SECTION 8.3 — Legal Description and is depicted on FIGURE 2 — PARCEL & AERIAL (APPENDIX A). A critical area for this report is defined as wetland, water (i.e. stream, river, pond, or lake), mapped floodplain or floodway, mapped and observed priority habitat, mapped and observed priority species, and other habitats and species considered locally to have special, sensitive, or important status. A total of twelve test plots were established in areas of homogeneous vegetation. The test plots and the boundaries of wetland and stream were marked with consecutively numbered colored flagging and were land surveyed, buffered, mapped, and areas calculated. All wetland and stream boundaries, categories, functional points, and classifications must be verified by agencies having jurisdiction. A summary of the findings are presented in SECTIONS 1.1 through 1.3. 1.1 WETLANDS Field verified wetlands were identified on the project site as depicted on FIGURE 5 — WETLAND & STREAM DELINEATION — 2014 and as summarized on TABLE 1 — WETLAND & STANDARD BUFFER DATA. Wetland characteristics are presented in TABLE 11 — WETLAND & BUFFER CHARACTERISTICS.

The work also included delineating and describing the functions, values, and characteristics of the identified wetlands and streams. Each delineated wetland was evaluated for five environmental functions: hydrologic support, storm and floodwater storage, water quality improvement, groundwater recharge, and biological habitat support. Performance of these tasks involved four interrelated steps: EnCo Wetland - Wildlife - Stream • Shoreline - Priority • Habitat Page 4 1. Preliminary research 2. Site assessment and study 3. Wetland and stream delineations with buffer determinations 4. Report preparation 3.0 BACKGROUND An initial site visit was performed with Mr. Landon Beyler, Professional Engineer with Beyler Consulting and Mr. Jonathan M. Kemp, Professional Wetland Scientist of EnCo on April 4, 2014. The purpose for performing this initial site visit was to determine the vegetation communities, drainage patterns, topography, and obvious critical areas on the site. Several historical orange wetland delineation flags were identified on the project site. The flags were very weathered; however the flags indicated that two wetland studies had been historically completed on the project site. One set of flags, labeled "LAI", was dated September 24, 2007 and the second set of flags was dated "March 10, 2002". EnCo contacted the City of Federal way planning department and they stated that they did not have any of these critical area reports on this property in their files. 4.0 PRELIMINARY RESEARCH Before initiating the field work published information and readily available maps depicting environmental resources, recorded data, and other applicable natural features were reviewed for evidence of previously identified or suspected wetlands, streams, priority habitat, and priority species on the project site and within about 330 feet from the project site. Researched sources are presented in SECTION 21.0 — REFERENCES. 5.0 SCOPE OF WORK The SCOPE OF WORK included performing the following subtasks: 1. Assessed the landscape and drainage features on the project site and to a limited extent on land located within a linear distance ranging from about 100 feet to 800 feet from developable or developed sections of the project site boundary for the critical areas defined in SECTION 1.0. 2. Established twelve (12) test plots in representative ecological communities on the project site. 3. Collected and evaluated test plot data for topographic features, drainage patterns, substrate, near surface hydrology, vegetation, habitat, and observed or indicators of animal and plant species. 4. Determined whether or not wetlands are located on the project site, and if present, marked the edges with consecutively numbered pink and black striped flags. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 5 5. Determined whether or not streams are located on the project site, and if present, marked the edge with pink or red flags. 6. Determined if the field verified wetland(s) and/or stream(s) are jurisdictional and regulated for protection and buffering. 7. Determined the class, category, type, and standard buffer widths for field verified and regulated wetlands and waters according to jurisdictional government agency regulations. 8. Performed a limited field reconnaissance for observed indicators of off -site wetlands and waters within a distance of about 330 feet from the project site boundary, including making an opinion on the potential for buffer encroachment onto the developable or developed sections of the project site from such areas. 9. Determined whether or not sensitive and / or priority habitat and species (PHS) or sensitive species are located on the project site and within a distance ranging from about 100 feet to about 800 feet from the project site boundary. 10. Prepared a series of FIGURES depicting the presence or absence of critical areas and other environmental and natural resources on and in the near vicinity to the project site. 11. Prepared a photographic log (PHOTOGRAPHIC LOG — APPENDIX G) depicting the test plots, observed landscape features, vegetation, soil, and ecological communities that were studied. 12. Reviewed a professional land survey (to scale) with delineated wetlands and flagged streams. 13. Prepared a report documenting the findings of the critical area determinations. 6.0 METHODOLOGY 6.1 REGULATORY AUTHORITY To conserve the benefits of wetlands and buffers, jurisdiction authority over activities in wetlands is exercised by federal, state, and local governments. The Clean Water Act (33 U.S.C. 1344) or Section 10 of the Rivers and Harbors Act (33 U.S.C. 403) were enacted by the U.S. Congress to restore and maintain water quality, biological integrity and chemical balance of all Waters of the United States. The Act empowered the U.S. Army Corps of Engineers (ACOE) with jurisdiction over filling of wetlands and authorized the U.S. Environmental Protection Agency (EPA) to oversee the ACOE fill permitting process. The Clean Water Act and the ACOE wetland manual defined wetlands as : "Those areas that are inundated or saturated by surface or ground water at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamp, marshes, bogs, and similar areas" (33 CFR 323). In 1987, the ACOE Wetlands Delineation Manual was issued to provide technical guidelines for identifying wetland, and provide supporting information and method for applying the technical guidelines. The 1987 Manual, along with other official guidance EnCo Wetland • Wildlife • Stream • Shoreline - Priority • Habitat Page 6 and manual updates, was relied upon for many years for wetland identification and delineation throughout the United States. In March 1997, the Washington Department of Ecology (ECOLOGY) Wetlands Delineation and Identification Manual was issued to provide technical guidelines for identifying wetlands specific to the State of Washington. ECOLOGY has updated and adopted the manual in August 2006. In April 2008 the ACOE completed a Western Mountains, Valleys, and Coast Region Regional Supplement that was part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland delineation procedures. The intent of this Regional Supplement is to bring the Corps Manual up to date with current knowledge and practice in the region and not to change the way wetlands are defined or identified. This Regional Supplement is designed for use the current version of the ACOE Manual (1987) and all subsequent versions. On June 30, 2014, ECOLOGY published the updates to the 2004 wetland rating systems for eastern and western Washington. The effective date of the 2014 rating systems will be January 1, 2015. This report followed the ECOLOGY 2004 wetland rating methods. This report has been prepared in accordance with the City of Federal Way as referenced in SECTION 21.0 — REFERENCES. 6.2 METHODOLOGY Wetland Critical areas were identified and determined by studying, collecting, and interpreting field data, by reviewing previously delineated wetland flags, agency correspondence, and violations (if any), agency parcel data sheets, interpreting readily available maps, conducting telephone and personal interviews, following the appropriate guidance for identifying and delineating critical areas, and by reviewing the most recent or vested edition of the jurisdictional government agency critical area regulations. Key definitions used during this project can be found in the documents referenced in SECTION 21 (REFERENCES). The wetland identification and delineation for this project followed the 2008 Western Washington regional supplement version to the 1987 edition of the United States ACOE Wetlands Delineation Manual as listed in SECTION 21.0 (REFERENCES). Buffers were determined from the City of Federal Way's critical area ordinance as referenced. Reportedly this dated manuscript is the edition or version that governs the identification and establishes protective measures (i.e. buffers) for critical areas. Excerpts from the referenced jurisdictional governmental agency critical area Code or Ordinance are presented in SUPPORT DOCUMENTS & RESUMES (APPENDIX E). EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 7 Wetlands and waters were classified and rated using several methods including the 1979 Coward Classification of Wetlands and Deepwater Habitats of the United States system, the United States Department of Interior, Fish and Wildlife Service NWI classification, and the cited edition of the ECOLOGY Washington State Rating System for Western Washington (Ratings Manual). The wetlands were qualitatively function rated in accordance with the criteria established by the referenced ratings manual and the jurisdictional government agency Critical Areas Ordinance. Copies of the completed ECOLOGY wetland rating forms are presented in APPENDIX C. Streams Water (i.e. streams) determination, classification, and typing methods followed the 2002 Washington Department of Natural Resources (WDNR) Forest Practices Manual Interim Water Typing System as amended on December 16, 2006 (WAC 222-16-031). The definitions cited in this report reflect the amended definitions. Priority Habitat and Species PHS determinations followed Washington Department of Fish & Wildlife (WDFW) an WDNR guidelines and the local jurisdictional governmental agency critical area regulations. Shorelines The Washington Shoreline Management Act (RCW 90.58.030 & WAC 222-16-030) and the referenced jurisdictional government agency regulate Shorelines and Shorelines of the State. 6.3 FIELD PROCEDURES The FIELD PROCEDURES undertaken followed acceptable industry practices and are presented as APPENDIX D. 7.0 SCHEDULE AND WEATHER CONDITIONS 7.1 SCHEDULE The assessment of the project site, collection of data, and critical area flagging was performed on September 4 and 5, 2014. The critical area study was performed by Mr. Jonathan Kemp, Professional Wetland Scientist of EnCo. Details of key personnel who worked on the delineation are presented in APPENDIX E (SUPPORT DOCUMENTS & RESUMES). EnCo Wetland - Wildlife • Stream - Shoreline - Priority - Habitat Page 8 7.2 WEATHER The weather conditions during the field work varied, ranging from partly cloudy to sunny skies. Ambient air temperatures ranged from 65OF to 75°F. Recorded precipitation (rain) which fell at the local weather station (Federal Way) during the time period from June 1, 2014 through September 5, 2014 is presented below (Weather Underground). The corresponding weather data sheets are presented in APPENDIX E.

The forest consists of several old growth and mature growth evergreen and deciduous trees. Many of these trees were observed to have been flagged by others. The landscape has been altered on the southern part by human impact by a former dwelling and access driveway. The remaining segment of the property is undisturbed. R Future Land Use The current landowner is planning for a change in land use from what is currently zoned for the site. The change in land use is a proposed single family residential development. EnCo Wetland - Wildlife • Stream • Shoreline • Priority • Habitat Page 9 Historical Land Use No information was researched or conveyed during the generation of this report regarding land use history, except for the old single family dwelling that was reportedly built in the 1920's and was demolished about 40 years ago. 8.2 SITE LOCATION The project site is located contiguously to the west of 39t" Street South, South 325th Place, and 326th Place as shown on FIGURE 1 — VICINITY & STREETS. The property is located completely within the jurisdiction of the City of Federal Way in King County. 8.3 LEGAL DESCRIPTION The legal description of the project site is listed in TABLE 4 — LEGAL DESCRIPTION & OTHER DATA.

The slope ranges from 0 percent to 6 percent with an overall trending downward westward aspect. The approximate altitude of the project site ranges between about 399 feet to 429 feet above mean sea level for a total relief of about 30 feet over a linear distance of about 780 feet as measured from the highest elevation near the northeast corner to the lowest elevation at the culvert crossing STREAM A near the west property boundary. A small, permanently flooded pond exists north of the northwest segment of the project site. The pond is about 7,245 square feet in size. The approximate elevation of WETLAND D ranges from 400 feet (north) to about 399 feet (south). Agency mapped elevation contours are depicted on FIGURE 3 — TOPOGRAPHY — FEDERAL (Poverty Bay) and the professional land surveyed elevations are depicted on FIGURE 5 (1 foot contours). A ground surface light detection and ranging (Lidar) map is presented as FIGURE 14 — GEOLOGIC LIDAR INVENTORY — COUNTY. The Lidar map is a remote sensing method used to examine the surface of the earth. DRAINAGE O Drainage Basin The project site is located in Water Resources Inventory Area Number 9 (Duwamish — Green River and Central Puget Sound). One drainage basin was identified on the project site that drains downward into the headwaters of North Lake. North Lake is about 55 acres in size and is located about 375 feet south of the project site. The North Lake watershed contains about 425 acres. The mean depth is 14 feet with a maximum depth of 34 feet. The lake is classified as being mesotrophic, indicating moderate productivity and good water quality. North Lake is located in the East Hylebos Creek Basin. The lake empties into a pond and then travels underground, via a pipe, to a wetland which then drains into the East Branch of the West Hylebos. The water then flows into the mainstem of the West Hylebos, which flows into Commencement Bay. A small stream (STREAM A) north of EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 11 North Lake drains to the south into the northern segment of the lake. North Lake lies on top of till and receives surface runoff from the surrounding uplands. North Lake is reportedly stocked with trout and largemouth bass. Salmonids inhabiting the East Hylebos Creek include Coho salmon, chum salmon, and cutthroat trout. A bald eagle nest has been identified within a quarter mile of North Lake; however this nest is not located on the project site. ® Surface Water Surface water was not observed on the forested area on the project site during the field study, however is assumed that during periods of heavy to moderate rainfall, water will flow as a sheet across the parcel via several very shallow natural drainage swales. Surface water flows as sheet flow into several small wetlands located in the southeast corner (WETLANDS A, B, & C). Surface water over the forested area enters the parcel by direct precipitation and as sheet runoff from upslope properties. Surface water in WETLANDS D & E flows as sheet flow and through a small ditched stream identified as STREAM A. Surface water trends across the site downward towards the west to southwest. 11.0 REGIONAL GEOLOGIC & SITE SOIL SETTING 11.1 REGIONAL GEOLOGIC SETTING Level III Ecoregion: Zone 2f — Central Puget Sound Lowland This region consists of broad rolling lowlands and is characterized by a mild maritime climate and flanks the intricately cut coastline of Puget Sound. It occupies a continental glacial trough and has many islands, peninsulas, and bays in the Puget Sound waterway. Coniferous forests originally grew on the ecoregion ground moraines, outwash plains, floodplains, floodways, and terraces. The distribution of forest species in some areas is affected by the rain shadow from the Olympic Mountains. Regional Geology The geology of Federal Way is summarized by Waldron (1961) and Booth and others (2004). The upland plain in this area is underlain by a sequence of glacial and non - glacial deposits that overlie Tertiary bedrock. The depth to bedrock is about 1,000 feet to 1,500 feet (Jones - 1996). The area has been glaciated six or more times in the past 2 million years. Each glacial advance likely left a sequence of deposits that consisted of fine-grained lacustrine deposits, outwash sand and gravel, and till. The lakes in this area are formed within these glacially derived deposits. Peat deposits are commonly associated with larger wetland areas within he watershed. The geomorphology of the Puget Sound Region, including the project site is typified by glacial outwash features (moraines) and drift uplands according to Kruckeberg (1991). EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 12 The most recent incursion of glacial ice into the central portion of the area is called the Vashon Stade of the Fraser glaciation, which receded from the area about 13,500 years ago. That glaciation is responsible for the majority of deposits that make up the surface of the upland plain. North -trending elongate hills, or drumlins, that form the surface of upland plain were shaped by the moving ice sheet. 11.2 SITE SOIL SETTING Soil Type Information pertaining to the soil types observed in the test plots is presented on the FIELD DATA FORMS (APPENDIX C). Based on interpretation from the on-line NRCS County Soil Survey map (Web Soil Survey), the original, undisturbed, mapped soil series identified at the ground surface and down to about 60 inches below ground surface (bgs) have been mapped as indicated below. It is important to note that the typical profiles, colors, depths, and textures presented below are not specific to the soils on the project site. The typical profiles were obtained by field soil scientists from reference sites in Washington as documented by NRCS. Alderwood Gravelly Sandy Loam — King County (AgB) The soil series mapped on about 85 percent of the eastern portion of the project site is classified as being Alderwood Gravelly Sandy Loam. The Alderwood series consists of moderately well drained soil and these soils were formed in glacial drift and deposits. These soils are on glacially modified foothills and valleys and have slopes that range from 0 percent to 66 percent (0 to 6 percent on the project site). The taxonomic class for the Alderwood series is loamy -skeletal, isotic, mesic Aquic Dystroxerepts. Alderwood soils are listed on the national hydric soils list. Elevation ranges from 100 feet to 800 feet. The mean annual precipitation is about 35 inches, the mean annual air temperature is about 50 degrees F, and the frost -free season averages about 200 days. In a typical profile, a thin mat of un-decomposed needles, leaves, and wood fragments overlies a 1 Y2 -inch, very dark grayish brown (10YR 3/2) gravelly sandy loam surface layer. The subsoil and the upper part of the substratum, to a depth of 38 inches, are dark yellowish brown (10YR 4/4), brown (10YR, 4/3), or dark grayish brown (10YR 4/2) gravelly sandy loam. The lower part of the substratum, to a depth of more than 60 inches, is weakly cemented, compact glacial till consisting of sandy gravels. Granite boulders and stones are strewn across some slopes. The depth to redox features with chroma 2 or less is 20 inches to 34 inches bgs. Reaction is moderately acid. A perched water table develops for short periods during the winter and spring rainy seasons. Permeability is very slow in the weakly cemented, compact part of the substratum. Commonly root growth is inhibited and roots are matted directly above this EnCo Wetland • Wildlife • Stream • Shoreline • Priority - Habitat Page 13 layer. The available water capacity is low. Surface runoff is very slow to slow and the erosion hazard is slight. The main limitation affecting the suitability of deep rooted crops is the weekly cemented substratum. In areas of moderate to high population, sewage disposal systems often fail or do not function properly during periods of high rainfall because of this restrictive layer. Vegetation consists of hardwoods and conifers. There are also some smaller crops including hay pastures, strawberries, cane fruit, and raspberries. Some areas are urbanely developed. Included Soil Series As much as 10 percent poorly drained Bellingham and Norma soils and very poorly drained Dupont soils and as much as 5 percent Everett soils can be geographically associated within this series in troughs. Other associated series can be Beausite, Kick, Hoogdal, Indianola, Kitsap, Quilcene, Skipopa and Whidbey. Orcas Peat — King County (Or) The soil series mapped on about 15 percent of the western portion of the project site is classified as being Orcas Peat. The Orcas series consists of very poorly drained soil that formed from sphagnum and hypnum mosses and some herbaceous plants. Many areas have been drained by ditching. These soils occupy depressions on glacial drift plains and have slopes that range from 0 percent to 2 percent. The taxonomic class for the Orcas series is dysic, mesic, Typic Sphagnofibrists. Orcas soils are listed on the national hydric soils list. Elevation ranges from 0 feet tol,000 feet, the mean annual precipitation is about 47 inches, the mean annual air temperature is about 50 degrees F, and the frost -free season averages about 200 days. In a typical profile, the top 4 inches consists of dark reddish brown (5YR 2/2), broken face, live fibric sphagnum moss (peat to mucky peat), dark reddish brown (5YR 3/4) pressed and rubbed; about 90 percent fibers; very friable, non -sticky, non -plastic, many very fine and fine roots; extremely acid (pH 4.4). From 4 inches to 12 inches bgs the soil consists of dark brown (7.5YR 3/2) broken face, peat; about 95 percent moss and fine root fibers with 10 percent hemic material; very acid. This layer is underlain with 12 inches to 60 inches or more of of brown (7.5YR 4/4), broken face, fibric material; about 95 percent fiber, reddish yellow (7.5YR 7/6) pressed and rubbed with less than 10 percent hemic material; massive; friable, non -sticky and non -plastic; extremely acid. Depth to mineral soil material ranges from 48 inches to more than 60 inches bgs. Few wood fragments are at any depth. Reaction is extremely acid. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 14 The water table is near the surface most of the year and the soil has a very high saturated hydraulic conductivity. Orcas soils are used for wildlife habitat and when drained are used for cranberries, blueberries, and pasture. The native vegetation is living sphagnum mosses, Labrador tea, wild cranberry, blueberry, and hardhack. Included Soil Series Geographically associated soils can include poorly drained Bellingham and Norma soils and very poorly drained Shalcar and Mukilteo soils. Other associated series can be Alderwood, Everett, and Harstine. Discussion Field observations indicate that the mapped primary soils within the project site wetland and upland communities primarily match the indicated NRCS County Soil Survey profiles and are, therefore, assumed not to be an inclusion within the mapped soil type(s). Upland soils in several areas on the project site were determined not to be hydric near the surface based on other field indicators (not color). 12.0 VEGETATION COMMUNITIES Vegetation on the project site was comprised of three general plant communities; two of which were hydrophytic and determined to be wetland. Mapped communities are depicted on FIGURE 2 — PARCEL & AERIAL and FIGURE 5 — WETLAND & STREAM DELINEATION — 2014. Community 1 The plants in Community 1 are not dominant hydrophytic and is classified as upland (non -wetland). This community is located east of Wetland D, north and west of Wetlands B & C and extends easterly to 39th Avenue South. This area is dominated in the tree strata by Douglas fir (Pseudotsuga menziesii), Western Red Cedar (Thuja plicata), and Big Leaf Maple (Acer macrophyllum). The shrub layer is dominated by Salal (Gaultheria shallon), Indium Plum (Oemleria cerasiformis), and Beaked Hazelnut (Cornus sericea). The herbaceous layer is dominated by Sword Fern (Polystichum munitum), Trailing Blackberry (Rubus ursinus), Stinging Nettle (Urtica dioica), and Sweet Scented Bedstraw (Galium triflorum). Moss coverage ranges from about 30 percent to about 80 percent. Community 2 The plants in Community 2 are dominant hydrophytic and is classified as wetland (WETLAND D). This community is located along the western portion of the project site and aligns next to the upland forest. The community starts at the toe of the upland EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 15 forested slope, includes a ditched stream, and extends westerly to the bog (WETLAND E). This area is dominated in the tree strata by Pacific Crab Apple (Malus fusca). A few large Oregon ash (Fraxinus latifolia) trees are scattered randomly near the north property boundary. The shrub layer is dominated by Sitka Willow (Salix sitchensis), Hooker Willow (Salix hookeriana), Pacific Willow (Salix lucida var. iasiandra), Hardhack (Spiraea douglasii), and Salmonberry (Rubus spectabilis). Herbs do not dominate in this community. Moss coverage ranges from 0 percent to about 15 percent. Community 3 The plants in Community 3 are dominant hydrophytic and is classified as wetland (WETLAND E — BOG). The community starts at the western edge of WETLAND D and extends to the western boundary of the project site and beyond. This area is dominated in the tree strata by widely scattered zones of Western Red Cedar (Thuja plicata). The shrub layer is dominated by Labrador Tea (Ledum groenlandicum) and Alaskan Blueberry (Vaccinium alaskaense). Herbs do not dominate in this community. Moss (Sphagnum sp) coverage ranges from 30 percent to 80 percent. Community 4 The plants in Community 4 are dominant hydrophytic and is classified as wetland (WETLANDS A, B, C). This community is located in the southeastern portion of the project site and aligns next to the upland forest and old driveway. This area is dominated in the tree strata by Western Red Cedar (Thuja plicata), Red Alder (Alnus rubra), and Black Cottonwood (Populus balsamifera). The shrub layer is dominated by Salmonberry (Rubus spectabilis), Red Alder saplings (Alnus rubra), and Twinberry Honeysuckle (Lonicera involucrata). The herb layer is dominated by Creeping Buttercup (Ranunculus repens), Lady Fern (Athyrium filix-femina), Stinging Nettle (Urtica dioica), and Tall Mannagrass (Glyceria elata). Moss coverage ranges from about 5 percent to about 65 percent. 13.0 WETLANDS 13.1 WETLAND INVENTORY — FIELD ASSESSMENT The presence or absence of wetlands on the project site was made by reviewing aerial photographs, national wetland inventory maps, local wetland inventory maps, stream maps, soil type maps, topography maps, floodplain / floodway maps, and other readily available geographic or natural resource maps. After the field work was completed the second part of the office assessment included studying and interpreting the test plot data and by reviewing digital photographs. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 16 Field verified project site wetlands met the technical requirements for being a wetland according to the established and accepted criteria for: 1. Wetland Hydrology 2. Hydric Soil 3. Dominant Hydrophytic Vegetation. The wetland determination was made by putting equal emphasis on all three wetland indicators. If the three wetland criteria was met then the feature was assessed to see if it is jurisdictional based on allowed exemptions such as being "isolated", "artificial', "small -size", "functionally exempt", or "exempt" for other allowed reasons. Based on this process, a final determination was made to determine if the feature is a jurisdictional wetland. Several plant community test plots on the project site were determined to be non - wetland (upland). The upland area does not contain well-defined depressions and does not collect or concentrate surface water runoff at or near the ground surface for extended periods of time. The soil type mapped on the forested area is classified as Alderwood Gravely Sandy Loam. This soil is listed as a hydric soil with the NRCS. However, the dominant hydrophytic vegetation criteria and the wetland hydrology criteria were not met in this forested area. The soils observed in the upland test plots consist of aerobic, dry, black to dark brown, gravelly silt loam with sand and did not exhibit depletions or redox concentrations in the upper foot bgs. Conclusive near ground surface and ground surface wetland hydrology indicators were absent in the upland plots unlike what was observed in the wetland plots. A restrictive layer of glacial till or dense gravels was not observed within 1.5 feet bgs in the test plots. The delineated wetland edge and standard buffer width was surveyed as depicted on FIGURE 5 — WETLAND & STREAM DELINEATION — 2014. A summary of the data for the field verified wetland is presented in TABLE 1 (SECTION 1.0) and in more detail in TABLE 11 — WETLAND & BUFFER CHARACTERISTICS (APPENDIX B). The wetland plot numbers and the consecutive wetland delineation flag numbers are referenced to the FIELD DATA FORMS presented in APPENDIX C and in TABLE 11. 13.1.1 WETLAND UNIT, CATEGORY, & STANDARD BUFFER ® Wetland Unit The wetlands were rated using the referenced ECOLOGY ratings manual. The field verified wetlands (WETLANDS D & E) were separated into a "sub -unit" for functional EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 17 rating because there was a significant change in the water regime at the confluence of North Lake. In addition, there are observed well-defined breaks in the vegetation patterns along the stream (STREAM A) as compared to the vegetation patterns along the shore of North Lake. Wetlands A, B, & C were not separated into "sub -units" because there was not a significant change in the water regime or vegetation patterns. Wetland Category The determined category for jurisdictional wetlands are based on size, diversity, rarity, water quality functions, hydrologic functions, habitat functions, status of PHS, riparian zone, sensitivity to disturbance, special characteristics, uniqueness, and documented environmentally sensitive areas. Wetland categories are defined in the ECOLOGY ratings manual (REFERENCES — SECTION 21). The determined category for the project site wetlands are listed below. WETLAND A = CATEGORY III WETLAND B = CATEGORY III WETLAND C = CATEGORY III WETLAND D = CATEGORY II WETLAND E = CATEGORY I 6 Wetland Buffer The standard wetland buffer was determined in accordance with criteria established in the referenced Critical Area Ordinance or Code. Wetland buffers are measured perpendicular to the delineated wetland edge. When a critical area buffer differs in width and overlap each other (i.e. stream buffers versus wetland buffers) the more restrictive buffer width applies. The local Critical Area Ordinance or Code allows buffer modifications such as averaging or reducing so long as specific criteria, conditions, and mitigating measures are met and the remaining buffer effectively protects the functions and values of the adjoining wetland. The determined widths of the standard buffer for the project site wetlands for the stated land use intensity and size thresholds are listed below. WETLAND A = 25' STANDARD BUFFER WETLAND B = 0' STANDARD BUFFER WETLAND C = 0' STANDARD BUFFER WETLAND D = 100' STANDARD BUFFER WETLAND E = 200' STANDARD BUFFER EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 18 13.1.2 CLIMATIC, NORMAL, DISTURBED, & PROBLEMATIC AREAS The determined status for climate, normal environmental conditions, being significantly disturbed (atypical), and problematic areas at each established test plot are presented in FIELD DATA FORMS — APPENDIX C. A summary of these conditions is presented on TABLE 10 — WETLAND & UPLAND DETERMINATION RATIONALE. Significantly disturbed and / or problematic areas were not identified in the delineated wetlands except at WETLANDS B & C. WETLAND B was determined to be significantly disturbed because the area was filled in with non-native soil, trash, appliances, metal parts, and junk. This impact has affected the near surface hydrology due to compaction and has caused an increase in wetland hydrology as compared to the landform in its natural state. WETLAND C was determined to be significantly disturbed because part of the wetland was filled with imported gravelly soil for the old driveway and part of the wetland was scarified and filled with imported soil, trash, and junk. This condition has affected the vegetation patterns, natural soil layers, and the near surface hydrology due to compaction and has caused an influx of nuisance vegetation, a more shallow upper soil profile, and has increased wetland hydrology as compared to the landform in its natural state. 13.1.3 SOIL i Soil Type The primary soil types and estimated layers observed in the near surface (within 18 inches bgs) in each established test plot are presented in the attached FIELD DATA FORMS. General soil types (4) for the project site wetlands are presented in TABLE 5 — SOIL TYPE OBSERVED IN WETLAND PLOTS.

If 50 percent of the root mass for herbs and shrubs is less than 6 inches bgs this highly indicates that the plants are growing in hydric soils, especially if other hydric soil indicators are present. Penetration readings at the established test plots which exceed 150 pounds per square inch (psi) have been shown by accredited university research to limit root growth (root inhibition). Penetration resistance levels observed in the test plots are listed in the attached FIELD DATA FORMS. 13.1.4 VEGETATION Dominant Hydrophytic Vegetation Dominant hydrophytic vegetation species observed in the established test plots are presented in the attached FIELD DATA FORMS. Dominant plants species identified in the hydrophytic plant communities in wetlands and in the upland community are presented in SECTION 12 — VEGETATION COMMUNITIES. Plant dominance was determined using the using the ACOE 50/20 rule. Hydrophytic plants are those plants listed with indicator status of OBL, FACK and/or FAC. The FAC-Neutral test was not employed for this study. 13.1.6 HYDROLOGY Generally, wetlands receive water support from one or more of the seven sources as listed below. 1. Surface water runoff from precipitation over natural areas in the wetland and surrounding upland 2. Surface water runoff from impervious or semi -imperious man -constructed developments and/or roadways 3. Over bank flow from rivers, streams, rivulets, ponds, lakes, estuaries, and oceans 4. Hyporheic (interstitial) flows from streams and other watercourses caused by water movement through sands, gravels, sediments, and other permeable soils under and beside open stream or other waterway beds. 5. Groundwater recharge from seeps, springs, or near surface water table confined on top of a hardpan or compacted glacial till layer. Seepage from groundwater into wetlands in alluvial plains can be caused by a near surface water -bearing layer that is semi -confined such as an underlying aquitard or aquiclude. Aquitards are layers whose permeability is much less than that of the aquifer itself and an aquiclude is a layer that is essentially impermeable. EnCo Wetland - Wildlife • Stream • Shoreline • Priority • Habitat Page 21 6. From intentionally installed artificial features such as roads, irrigation systems, dams, swales, irrigation canals, detention facilities, wastewater treatment facilities, farm ponds, drainage ditches, and landscape amenities 7. From unintentionally created features such as gravel mining or borrowing, mineral mining, and oil and gas exploration Wetland hydrology is supported by one of five types of water movement: 1. Flow through 2. In flow 3. Hyporheic flow 4. Flat (no flow) 5. Lentic (shorelines and lakes) Wetland Hydrology Indicators Wetland hydrology was determined by observing degree of moisture, inundation, and/or saturation conditions in hand -dug test pits and by observing other hydrology indicators in the plot area and test hole. Wetland hydrology can be inferred from plots with positive hydric soil indicators and dominant hydrophytic vegetation if seasonally dry conditions prevail and if the landform is conducive to support wetlands. Field verified positive wetland hydrology indicators observed in the wetlands are presented in the attached FIELD DATA FORMS. Due to recent normal weather conditions wetland hydrology indicators were relatively easy to determine. Positive wetland hydrology indicators (4) that were field verified in the wetlands are listed in TABLE 7 — WETLAND HYDROLOGY INDICATORS IN WETLAND PLOTS. Note: G.S. in the table refers to the regional "Growing Season". Additional information pertaining to the observed wetland hydrology is presented in the attached FIELD DATA FORMS.

Wetlands provide value to mankind such as by providing scenic diversity, aesthetic value to the natural landscape, and wellness initiatives that support mind and body. The function rating for water quality, hydrologic, and habitat for the delineated wetlands were made using the referenced wetland rating manual. The ECOLOGY wetland rating system is not an accurate method for determining water quality, hydrologic, and habitat functions when compared to using the more detailed Washington State Function Assessment method. The limited functional analysis presented in this report is strictly a qualitative rating for high, moderate, and low levels of function in a wetland and is not to be used as a numerical quantitative method. The qualitative rating of functions using the referenced ECOLOGY ratings manual was designed to help determine buffer widths and/or buffer width modifications needed to protect the identified functions in jurisdictional wetlands. The determined functions for each of the wetlands are presented below and summarized in TABLE 1. • Water Quality Function The range of water quality function scores for three general levels of protection is based on the qualitative scores obtained by using the referenced ECOLOGY rating manual. The function ranges for depressional and flat wetlands are listed below. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 25 Water Quali4y Function (Depressional / Flat) Maximum Points Attainable: High Level of Function Moderate Level of Function Low Level of Function Wetland Function Levels: High: Moderate: WETLANDS D & E Low: WETLANDS A, B, & C Wetland Rating Points 32 points 25 to 32 points 17 to 24 points <17 points N/A 22 points 8 to 10 points Water quality function scores are rated based on the potential and opportunity to improve water quality as rated from selected environmental factors and conditions. The factors to potentially improve water quality include the characteristics of surface water flows out of the wetland, the type of soil (organic, clary, or mineral) in the top 2 inches, the characteristics and classes of persistent vegetation, and the characteristics of seasonal ponding or inundation. The factors to improve the opportunity to improve water quality include the degree of animal grazing, untreated stormwater discharges, drainage from tilled fields, farm fields, orchards, golf courses, developed urban and residential areas, roads, and clear-cut logging areas. The factors also include the degree of human impacts that could raise levels of sediment, toxic compounds, or nutrients (i.e. phosphorous and nitrogen) into the waterway. Water Quality Function points are recorded on the ECOLOGY rating form used to rate the wetland. D Hydrologic Function The range of hydrologic function score for three general levels of protection is based on the qualitative scores obtained by using the referenced ECOLOGY ratings manual. The function ranges for depressional and flat wetlands are listed below. Hydrologic Function (Depressionai / Flat) Maximum Points Attainable: High Level of Function Moderate Level of Function Low Level of Function Wetland Rating Points 32 points 24 to 32 points 16 to 23 points <16 points EnCo Wetland • Wildlife - Stream • Shoreline • Priority • Habitat Page 26 Wetland Function Levels High: N/A Moderate: N/A Low: WETLANDS A, B, C, D & E 9 to 12 points Hydrologic function scores are rated based on the potential and opportunity to reduce flooding and stream erosion as rated from selected environmental factors and conditions. The factors to potentially reduce flooding and stream erosion include characteristics of surface water flows out of the wetland, depth of storage of water during wet periods, and the contribution of the wetland unit to the storage of water in the watershed. The factors to improve the opportunity to reduce flooding and stream erosion include determining if the wetland is in a headwater of a river or stream that has flooding problems, if the wetland drains to a river or stream that has flooding problems, and if the wetland has no outlet and impounds surface runoff that might otherwise flow into a river or stream that has flooding problems. Hydrologic Function points are recorded on the ECOLOGY rating form used to rate the wetland. ® Habitat Function The range of habitat function scores for nine general levels of protection is based on the qualitative scores obtained by using the referenced ECOLOGY ratings manual. The function ranges for habitat function for all classes of wetlands are listed below. Habitat Function (All Wetland Classes Maximum Points Attainable: High Level of Function Moderate Level of Function Low Level of Function Wetland Function Levels (All Wetlands): Wetland Rating Points 36 points 29 to 36 points 20 to 28 points <20 points High: N/A Moderate: WETLANDS B, D & E 22 to 23 points Low: WETLANDS A & C 16 to 17 points Habitat function scores are rated based on selected environmental factors and conditions. The factors for habitat function include the type of vegetation structure, hydroperiods, richness of plant species, interspersion of habitats, special habitat features, condition and disturbance level of buffers, the size and width of corridors and connections, number of adjacent or nearby priority habitats, and the condition of the EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 27 wetland and upland landscape. Habitat Function points are recorded on the ECOLOGY rating form used to rate the wetland. Wetlands with high to moderate habitat function scores provides good and adequate cover for song birds, and small mammals including squirrels, chipmunks, rabbits, moles, raccoon, possum, porcupine, and mice. Wetlands also can provide excellent habitat for amphibians such as the Pacific tree frog and reptiles such as the Gardner snake. Having several different classes of vegetation structure in a wetland provides an opportunity for a diverse group of animals to reproduce, prey, move, rest, eat, and live due to the patchiness, density, and height of the plants. Wetlands with several hydroperiods throughout the growing season provide an opportunity for a more diverse population of invertebrates, birds, amphibians, and reptiles to reproduce, feed, and live. Increased richness of plant species provides a wide variety of fruit, berry, pollen, nectar, bud, leaf, twig, bark, sap, cone, seed, grain, nut, acorn, bulb and corm material for animals to feed on. Interspersion of vegetation classes in a wetland provides opportunity for many species of plants to thrive which provides many habitat niches for the needs of many types of wildlife and fish. Special habitat features such as snags, down wood, runner logs, brush piles, undercut and stable steep banks, and overhanging branches over open water provides very good and unique habitats for a diverse group of invertebrates, mammals, amphibians, reptiles, passerine birds, woodpeckers, and raptors. Areas infested with invasive plant species provides less opportunity for establishment of native plants and animals due to the mono-typic nature of aerial cover of the invasive species. Undisturbed corridors provide quality urban habitat for movement of larger mammals such as deer, coyote, and elk. 13.1.8 WETLAND BUFFER MODIFICATIONS OR EXEMPTIONS m Small -Sized Wetland Modification or Exemption to Standard Buffers The City of Federal Way Critical Area Ordinance allows, with conditions, a modification and/or an exemption for buffering for Category III wetlands as listed below. Wetland Category Wetland Size Threshold III 2,500 SF to 10,000 SF III <2,500 SF IV Not in City Code EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 28 Small Size Buffer 25' 0' WETLANDS A, B, & C qualify for the small -sized wetland modification as shown below. Wetland Wetland Size Modified Standard Buffer WETLAND A 3,221 SF 25' WETLAND B 1,272 SF 0' WETLAND C 1,103 SF 0' 0 Other Exceptions or Allowed Land Uses in Critical Areas Applicants may apply for a variance to modify a critical area and/or its buffer beyond what is allowed by the general protection standards. Modifying a wetland and/or its associated buffer width below what is allowed by general standards will more than likely require mitigating measures, added permit fees, or other conditions. Mitigation measures may include wetland and/or buffer creation, replacement, restoration, and/or vegetation and habitat feature enhancements with construction and long-term compliance monitoring. Exceptions may be allowed if the applicant can show that the proposed activity or chance in land use will not degrade the functions and values of the critical area or may be allowed (with restrictions) for installing and maintaining certain utilities, public access points, and stormwater management systems. In many cases current land use activities that encroach within regulated wetland buffers can be grandfathered and can continue or be re -built as long as the existing land use designation or zoning does not change. Activities allowed in critical area buffers are specified in the jurisdictional governmental agency regulations. Utility easements, roadways, right-of-ways, access ways, agriculture, and other non or less -intrusive land uses may be allowed to some degree in critical area buffers. Construction of stormwater management facilities having no reasonable alternative on the project site may be allowed in the outer periphery of buffers (depends on wetland category or water type). Discharges from stormwater facilities must be designed to protect critical areas such as wetlands and streams by treating the surface water and minimize erosion impacts with engineered spreader trenches, rip rap, liners, or other means. Other examples of activities that can be allowed in buffers (with conditions) are those which have a minimal adverse impact on buffers and critical areas such as low intensity passive recreational activities, pervious trails, nonpermanent wildlife watching blinds, short term scientific or education activities, exploration and test pits, and sports fishing or hunting. In some cases the governing agency may consult with a private consulting firm, ACOE, or ECOLOGY to make the final determination as to whether an area meets the criteria to be a wetland or whether or not the wetland is "small -sized", "isolated", "hydrologically EnCo Wetland • Wildlife - Stream • Shoreline • Priority • Habitat Page 29 isolated", and/or an "adjacent" wetland. Governing agencies will determine whether or not permits are required for any proposed alteration or disturbance of critical areas. Wetlands determined by the ACOE to be non jurisdictional due to their isolation from navigable Waters of the State are in many cases still regulated by ECOLOGY. In some cases "small -sized", "isolated", "hydrologically isolated" and "adjacent" wetlands can be dredged or filled in with agency authorization, permits, or with an approved compensatory mitigation plan. Placement of fill material into, or scarifying, dredging or ditching material out of any critical area is not advised unless authorized in writing by the jurisdictional governmental agency. Local permits may be required for instances where greater than 50 cubic yards are excavated and State SEPA permits may be required when greater than 250 cubic yards of material are excavated. The ACOE regulates disruptive activities in wetlands, not wetland buffers. Section 404 of the Federal Clean Water Act prohibit the discharge of pollutants and dredge and fill material into the nation's navigable waters, including most non -isolated wetlands and tributaries, without obtaining authorization and/or a permit from the ACOE. If a wetland is determined by the ACOE to be a Water of the State then either a Nationwide General Permit or an Individual Permit will more than likely be required for the planned disturbance. Generally a Nationwide General permit will be required if the size of the impacted area in the wetland exceeds 1/10 of an acre, otherwise an Individual Permit may be required. Crossing, building, or creating a disturbance into streams, rivers, shorelines, or other Waters of the State may require a WDFW Hydraulic Project Approval permit. Agricultural land governed under Natural Resources Conservation District jurisdiction requires landowners to delineate wetlands using the National Food Security Act Manual. In some cases if the agricultural land is certified as being a "prior converted" wetland the land may be exempt from jurisdictional wetland regulations. Dwelling Density Credits For developments on lands containing wetlands and wetland buffers the governing agency may allow adjustments (i.e. increased dwelling unit density) beyond the allowable zoning dwelling unit density based on specific formulas that are related to the percentage of the site in wetland and water buffers and other "green" or open space. The density credits are usually designed to provide incentives for the preservation of wetland, wetland buffers, and green space to provide flexibility in the design, and to provide consistent treatment for different types of development proposals. In some cases the developments' open space requirement may be satisfied by wetland and/or wetland area buffers. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 30 13.1.9 OFF -SITE WETLANDS The presence or absence of off -site wetlands within about 330 feet from the project site was assessed by interpretation of readily available maps from federal, state, county, local, and /or from other documented resources. The distance from off -site wetland edges to the project site was estimated by scaling readily available color aerial maps and estimating where the critical area is located by observed changes in color, shadows, vegetation or topography. The estimated reach of off -site wetland buffers do not encroach onto developed land on the project site as shown on FIGURE 6. 13.2 WETLAND INVENTORY — FEDERAL Mapped NWI wetlands were identified on the project site and within 330 feet from the property boundary as depicted on FIGURE 6 — WETLAND INVENTORY — FEDERAL. NWI wetlands are referenced as NWI-A (On -Site) and as NWI-1 (Off -Site). Mapped NWI wetlands are listed in a clockwise direction starting from a northern compass direction. NWI-A A mapped PSS/EMC NWI wetland is depicted on the western quarter of the project site. A NWI PSS/EMC designation by USFWS is classified as a mixed palustrine scrub shrub and emergent wetland that is seasonally flooded. NWI-1 An off -site mapped PEM/SSF NWI wetland is depicted about 110 feet south of the southwest corner of the project site. The wetland is associated with the back waters of North Lake. The estimated reach of this off -site wetland buffer (100 Feet) does not encroach onto developed land on the project site.

EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 31 An NWI L2ABH designation by USFWS is classified as a lacustrine littoral wetland with an aquatic bed that is permanently flooded. 13.3 WETLAND INVENTORY — STATE The WDNR in cooperation with the WDFW, ECOLOGY, and affected Indian Tribes have classified wetlands for state lands. The wetlands have been classified in order to distinguish those which require wetland management zones and those which do not. Mapped WDNR wetlands or open water were not identified on the project site as depicted on FIGURE 9 — WATER INVENTORY — STATE. An off -site WDNR mapped wetland (Open Water) is depicted about 130 feet south of the southwest property boundary. The off -site wetland is associated with North Lake. The estimated reach of off -site wetland buffer from North Lake (100 Feet — Category II / 50 Feet — Category III) does not appear to encroach onto developed or developable land on the project site as shown on FIGURE 9. 13.4 WETLAND INVENTORY — COUNTY The County maintains several databases that contain information on wetlands that must be considered in many land use decisions and activities. The information is maintained in a centralized data base and mapping system (iMAP). Mapped King County wetlands or open water were identified on the project site as depicted on FIGURE 7 — WETLAND & WATER INVENTORY — COUNTY. The county map is based on the 1990 wetland survey. An off -site King County mapped wetland (Green Hatch) is depicted about 150 feet southwest of the southwest corner and open water (Blue Hatch — North Lake) is located about 100 feet south of the southwest corner of the project site boundary. The estimated reach of off -site wetland buffer (100 Feet — Category II / 50 Feet — Category III) does not appear to encroach onto developed or developable land on the project site as shown on FIGURE 7. 13.5 WETLAND INVENTORY — CITY Mapped Federal Way wetlands were identified on the project site as depicted on FIGURE 8 — WETLAND & WATER INVENTORY — CITY.

Standard shoreline setbacks are based on the designated land use and are presented below. Standard Shoreline Setbacks Single Family Dwelling: 50' Multi Family Dwelling: 75' Conservancy: 200' 14.0 WATERS 14.1 WATER INVENTORY — FIELD ASSESSMENT The presence or absence of waters on the project site was made by studying test plot data, digital photographs, and by reviewing aerial photographs, national wetland inventory maps, local wetland inventory maps, stream maps, soil type maps, topography maps, floodplain maps, and other readily available geographic or natural resource maps. Field verified project site waters had to meet the technical requirements for being a stream according to criteria established by WDFW and WDNR which states there must be a definable scour channel with a bed, have bank full widths greater than 2 feet wide on average, and must be landscape positioned to be contiguous to a Water of the State. Waters were identified on the project site. The estimated stream edge, ordinary high water mark, and the standard stream buffer width was surveyed and plotted as depicted on FIGURE 5 — WETLAND & WATER DELINEATION. A summary of the data for the field verified water is presented in TABLE 2, SECTION 1.0 and in more detail in TABLE 12 — WATER & BUFFER CHARACTERISTICS (APPENDIX B). The stream plot numbers and the consecutive stream flags numbers are referenced to the FIELD DATA FORMS presented in APPENDIX C and in TABLE 12 — WATER & BUFFER CHARACTERISTICS. 14.1.1 WATER TYPE & BUFFER ® Water Type Water types were determined in accordance with the criteria established by the referenced 2002 WDNR water typing program as amended in 2006 and the City Critical Area Ordinance. The water type for field verified waters is based on state shoreline status, substrate, bed, scour channel, period of surface water flow, flow rate, depth and width of surface water, pools, riffles, ordinary high water mark, bank characteristics, EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 33 gradient (slope), anadromous and resident fish use, priority or locally important species use, priority habitat characteristics, riparian zones, and special characteristics. The determined type for STREAM A is listed below. STREAM A: TYPE = F / 3 A Type F water is defined by WDNR as "Streams and waterbodies that are known to be used by fish, or meet the physical criteria to be potentially used by fish. Fish streams may or may not have flowing water all year, they may be perennial or seasonal." ® Water Buffer Water buffers were determined in accordance with criteria established by the local Critical Area Ordinance and/or according to an approved WDFW HPA permit (n/a). Water buffers have been established to protect instream fish habitat thereby controlling or minimizing temperature variances, preventing sediments from entering into streams, preserving wildlife habitat, and allowing open connection to riparian zones and upland habitat. Water buffers are measured perpendicular to either the ordinary high water mark (OHWM) or outward from the outer edge of the floodway unless special conditions exist such as shoreline status, steep slopes, ravines, and/or riparian zones. When water, wetland, or other critical area buffers differ in width and overlap each other the more restrictive buffer width will apply. Generally a riparian habitat buffer is measured outward in each direction, on the horizontal plane, form the ordinary high water mark OR from the outer edge of the floodway or stream, whichever is greater. A riparian habitat zone was not identified on the project site. The determined standard buffer width for STREAM A is listed below. STREAM A: STANDARD BUFFER = 100 Feet 14.1.2 RATIONALE FOR WATER DETERMINATION A summary of the rationale for making the water determination is listed below. Test plots locations are depicted on FIGURE 5 and collected data pertaining to the water determination is presented on the attached FIELD DATA FORMS.

The estimated reach of off -site buffers for off -site streams do not encroach onto developed or developable land on the project site as shown on FIGURES 9 & 10. 14.2 WATER INVENTORY — STATE The WDNR maintains several databases that contain information on streams that must be considered in many land use decisions and activities. The information distributed by WDNR includes data that is maintained in a centralized data base and mapping system. Agency maps document the location of streams and in some cases wetlands based on field studies and reported sightings. Forest Practices Application Review System (FPARS) is a WDNR web -based, interactive map developed for citizens, landowners, cities and counties, tribal governments, other agencies, developers, conservation groups, and interested parties to find basic information about the known location of streams and their types. The program is a source of best available science that informs local planning activities, development projects, conservation strategies, incentive programs, and numerous other land use applications. The FPARS map displays known locations of streams and in some cases wetlands that have been provided to the department by agency biologists, reported by the public, aerial photographs, agency maps, and other sources of scientific data. Data is updated as new information is gathered and verified in the field. This map is not an exhaustive survey of all streams. The data displayed on the FPARS program is for informational purposes only. The specific location of all streams may not be depicted on the FPARS map.

The mapped stream is associated with the field verified STREAM A. 14.5 FLOODPLAIN INVENTORY —FEDERAL Mapped FEMA floodplains and / or floodways were identified on the project as depicted on FIGURE 11 — FLOODPLAIN INVENTORY — FEDERAL. The project site is mapped as being in Zone X on Panel Number 53033C1250F dated May 16, 1995. It should be noted that the floodplain map did not provide a specific zone label at North Lake. Zone X (100 year) — includes area inundated by 100-year flooding; an area inundated by 100-year flooding with average depths of less than 1 foot or with drainage areas less than one square mile; or an area protected by levees from 100-year flooding. A Zone X floodplain designation is determined to have a Low to Moderate Risk of Flooding. 15.0 PRIORITY HABITAT & SPECIES The presence or absence of project site PHS was made by performing a cursory habitat assessment. The assessment included documenting observed sightings, vocalizations, field indicators, or other evidence, performing research, interpreting readily available maps, and other documented resources. The determination for presence or absence of PHS is based on the time and date in the field and does not reflect diurnal or seasonal variances. Methods generally followed the WDFW criteria for assessing priority habitat that included observing: 1. Habitat that is relatively important to various species of native fish and wildlife 2. The terrestrial landscape that is influenced by or that directly has influence to an aquatic ecosystem 3. Transitional landscape between terrestrial and aquatic systems where the water table is usually at or near the ground surface or the land is covered by shallow water 4. The combination of physical, biological, and chemical processes and conditions that interact to provide functional life history requirements for instream fish and wildlife resources EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 36 5. Dead or dying trees that exhibit sufficient decay characteristics to enable cavity excavation and/or use by wildlife 6. High quality native wetlands and wetlands that support threatened and endangered fish and wildlife Habitats listed by WDFW as being priority include: 1. Aspen Stands 2. Biodiversity Areas and Corridors 3. Herbaceous Balds 4. Old -Growth / Mature Forests 5. Oregon White Oak 6. Riparian 7. Westside Prairie 8. I nstream 9. Nearshore 10. Caves 11. Cliffs 12.Talus 13. Snags and Logs The results of the WDFW PHS program database search for the project site and within a distance ranging from about 100 feet to 800 feet from the project site are listed in TABLE 13 — PRIORITY HABITAT & SPECIES CHARACTERISTICS and are depicted on FIGURE 12 — PRIORITY HABITAT & SPECIES INVENTORY — STATE and on FIGURE 13 — FISH & WILDLIFE HABITAT INVENTORY — CITY. 16.1 PRIORITY HABITAT & SPECIES INVENTORY— FIELD ASSESSMENT The project site contains suitable habitat for native wildlife and animal species common to tree, scrub/shrub, and emergent classes of vegetation in both upland and wetland communities in the Puget Sound Lowland Ecoregion that are low to moderately developed and moderately disturbed. Observed habitat and species are listed below. 15.1.1 SNAG & DOWN WOOD Decaying snags with bark and downed logs with bark are important to wildlife because they provide cover from predation (cavities), nesting resources, predation for raptors, and they attract insect populations, which provide a good food resource for many birds.

Western Red Cedar Trees 3. Douglas Fir Trees 4. Big Leaf Maple Trees 15.1.3 AMPHIBIAN & REPTILE The distribution and habitat use for amphibians and reptiles is not as well-known as compared to those of other vertebrate species in the Pacific Northwest. Many amphibians rely on wetlands and waters for breeding habitat. Several species are known to breed in fallen logs, shallow roots, shallow surface water, grass -lined wetland edges, and duff in forested areas and are active feeders in forest communities during wet weather periods. Most species of this group are very secretive and can be seen only during short periods of their life cycles. Surveys for such species require special techniques to adequately inventory these creatures. Species commonly found in the project site habitat are Pacific tree frogs and Gardner snake. Observed amphibians and reptiles and evidence or indicators of such animals are listed below. Amphibians Observed ■ None Evidence or Indicator 0 Frog chirps (pacific tree frog) Suitable Habitat • Intermittent flowing stream (STREAM A to Pond and North Lake) • Good shading in areas with overhanging shrubs over water and ground • Shallow surface water in floodway of stream • Grass -lined wetland edge EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 38 • Undisturbed corridor in floodplain and floodway of stream • Large woody debris with bark Good vegetation structure • Moderate richness of plant species • Moderate interspersion of habitats in the stream • Adequate forest duff layer with good moisture at the ground surface • Tree cavities and exposed unearthed roots near ground surface Reptiles Observed • None Evidence or Indicator m None Suitable Habitat o Intermittent flowing stream (STREAM A to Pond and North Lake) • Good shading in areas with overhanging shrubs over water and ground Shallow surface water in floodway of stream • Undisturbed corridor in floodplain and floodway of the stream • Moderate interspersion of habitats in the stream Adequate forest duff layer with good moisture at the ground surface Large woody debris for sunning • Sun facing stones or rocks for sunning • Persistent herbs and shrubs for sunning Tree cavities and exposed unearthed roots near ground surface • Dug out dens / burrows in gravelly soils 15.1.4 BIRD Most birds generally exhibit secretive habits and are difficult to observe without performing detailed field surveys which may include intrusive work such as constructing blinds for visual identification. Observed Several different species of song birds (Passerine) were observed perched on the branches of trees and shrubs, feeding in shrubs, and at the ground surface. Shrubs observed inhabited with birds include berry -producing shrubs such as blackberry and salmonberry and cone producing trees such as Douglas fir, Western red cedar, and red alder. Birds were observed in areas with abundant flying and water -loving invertebrates EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 39 (aquatic and terrestrial) and in low, damp areas populated with worms, snails, and slugs. Birds to be expected in this area could including great blue heron, red-tailed hawk, eagle, osprey, owl, red pileated woodpecker, flicker, fly catcher, blue jay, nuthatch, wren, goldfinch, towhee, bushtit, finch, sparrow, crow, titmice, vireo, warbler, chickadee, robin, swallow, and hummingbird. Observed birds and evidence or indicators of such animals are listed below. • American crow e Black cap chickadee • House wren 8 Blue jay Red tailed hawk (fly over and calls) ® Great Blue Heron (fly over) Evidence or Indicator • Unidentified songs from passerine bird in shrubs • Feathers observed on the ground surface in the forested area • Woodpecker holes in trees and snags • Broken egg shells Suitable Habitat • Bird perches • Snags for birds of prey • Berry producing shrubs Cavities in trees for nests or rest • Well protected shrubs and trees for nests • Intermittent flowing stream for water source (Pond, STREAM A, North Lake) • Undisturbed corridor in the bog, wetlands, and uplands • Good vegetation structure in the bog Moderate richness of plant species Moderate interspersion of habitat in the bog Large woody debris 15.1.5 FISH Lakes, ponds, streams, and rivers stocked with game fish as defined by RCW 77.08.020 by WDFW are not located on the project site. However it is likely that North Lake is stocked with game fish (not confirmed). Observed fish and evidence or indicators of such animals are listed below.

In addition, many mammals are nocturnal and are not very active during daylight hours. Dangerous mammals, such as black bear and cougar, could be expected to feed, move, and roam on and near the project site due to the extent of undisturbed corridors and moderate human interference in areas located north of North Lake. Hindrance to dangerous mammals include the extent of development and traffic on nearby streets. The wetland and stream provides suitable habitat for squirrel, chip monk, raccoon, rabbit, skunk, opossum, shrews, moles, voles, rat, bat, deer, and coyote. Observed mammals and evidence or indicators of such animals are listed below. Observed • Grey squirrel • Chipmunk Evidence or Indicator • Animal trails • Matted vegetation and duff in cavities and dens in trees in upland • Scat near stumps of trees • Mammal bones and fur in upland • Deer and rabbit scat on animal trails • Dens and burrows in the gravelly upland soils EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 41 Suitable Habitat • Intermittent flowing stream (STREAM A, Pond, North Lake) • Good vegetation structure • Good food source • Good water source • Moderate richness of plant species • Moderate interspersion of habitats in the stream and bog Large woody debris and runner logs • Vegetated wetland and stream buffer 15.1.7 MOLLUSK Observed mollusks and evidence or indicators of such animals are listed below.

The information distributed by WDFW includes data that is maintained in a centralized data base and mapping system. Agency maps document the location of important wildlife resources based on field studies and reported sightings. PHS on the Web is a WDFW web -based, interactive map developed for citizens, landowners, cities and counties, tribal governments, other agencies, developers, conservation groups, and interested parties to find basic information about the known location of PHS. PHS is a source of best available science that informs local planning activities, development projects, conservation strategies, incentive programs, and numerous other land use applications. The PHS on the Web map displays known locations of priority habitats and species that have been provided to the department by agency biologists, reported by the public, and other sources of scientific data about species and habitat locations. Data is updated as new information is gathered and verified in the field. This map is not an exhaustive survey of all fish and wildlife presence. The data displayed on PHS on the Web is for informational purposes only. The specific location of some fish and wildlife information is not available on PHS on the Web. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 43 These locations deemed "sensitive" by WDFW and are not displayed on the map beyond a certain resolution (e.g. Township or Section) due to an increased risk of human interference. Mapped WDFW PHS was identified on the project site as depicted on FIGURE 12 — PRIORITY HABITAT & SPECIES INVENTORY — STATE. The City of Federal Way uses the databases available from the WDFW PHS program. 1. A WDFW mapped PHS unit (Species & Habitat Polygon) is depicted on the western quarter of the project site. The species and habitat polygon is associated with WETLANDS D & E. Mapped WDFW PHS was identified with about 800 feet from the project site as depicted on FIGURE 12 — PRIORITY HABITAT & SPECIES INVENTORY — STATE. An off -site WDFW mapped PHS unit (Habitat Line) is depicted about 100 feet south of the southwest corner of the project site. The species and habitat line is associated with STREAM A. The estimated reach of the 100 foot buffer from the off -site PHS stream does appear to encroach onto developed or developable land on the project site as shown on FIGURE 12. 2. An off -site WDFW mapped PHS unit (Species & Habitat Polygon) is depicted about 375 feet south of the southwest corner of the project site. The polygon is associated with North Lake (Lacustrine Littoral System).

The City of Federal Way uses the state PHS inventory maps for their priority habitats and species. 15.4 SIGNIFICANT TREES — CITY Significant trees were identified on the project site. Significant trees include Douglas Fir, Western Red Cedar, and Big Leaf Maple. Many of these trees were flagged by another party. The City of Federal Way does not have a Significant Tree ordinance, rather they have a tree retention ordinance referenced as code number 19.120.130-1 and -2. 16.0 BUILDING SETBACK The capital structure and building setback was determined from the referenced jurisdictional government agency regulations. Building setbacks are measured from the property boundaries, buildings, streets, alleyways, utilities, and edges of wetland, water, PHS, and critical area buffers. EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 44 Government Agency Building Setback The building setback for the City of Federal Way is presented below. Front 20' Rear 5' Side Interior 5' Side Street 10, Critical Area 15' 17.0 POTENTIAL AND /OR EXISTING IMPACTS The proposed project will not degrade the functions of the wetlands and streams if the development does not encroach within the standard buffers or if buffer mitigation is established for buffer width modifications. In addition the functions of wetland and streams will not be impacted if stormwater runoff is properly managed and of infrastructure and buildings are designed according to City code. Modifications to buffer widths will be allowed if mitigation is undertaken and if the averaged or reduced buffer meets the following criteria: 1. It will not adversely affect water quality. 2. It will not adversely affect the existing quality of the wetland's or buffer's wildlife habitat. 3. It will result in no net loss of wetland area, function or value. 4. It will not adversely affect neither drainage nor stormwater retention capabilities. 5. It will not lead to unstable earth conditions nor create erosion hazards. 6. It will not be materially detrimental to any other property in the area of the project site nor to the city as a whole, including the loss of open space. 7. The project is is the best interest of the public health, safety, or welfare. 8. The applicant has demonstrated sufficient scientific expertise and supervisory capability to carry out the project. 9. The applicant is committed to monitoring the project and to making corrections if the project fails to meet projected goals. 18.0 EXCLUSIONS & LIMITATIONS TERMS & CONDITIONS (APPENDIX F) for the work effort are an integral part of this report and must be read and understood. This report is presented without warranty, express or implied, except that the services associated with this report are rendered by EnCo in good faith and according to the standards generally practiced by professional wetland scientists in the area of wetland and stream evaluation. The critical area determination was limited to the portions of the project site that were studied and assessed as defined in this report and as directed by the client or regulatory EnCo Wetland • Wildlife • Stream • Shoreline • Priority • Habitat Page 45 agencies. If the referenced version of the local critical area Ordinance or Code is determined by others not to apply to this project then EnCo may need to revise the content, buffer widths, and conclusions presented in this report. The work did not include detailed assessment of any off -site properties in order to prevent trespassing. A field reconnaissance was performed on land located beyond the project site as observed from accessible public access ways such as roads, open green space, easements, or alley ways. All wetland and stream boundaries and buffers are subject to verification by agencies having jurisdiction. The geospatial accuracy of the prepared agency figures may not be an accurate depiction of the property boundary, critical areas, buffer edges, and PHS lines or polygons. Site maps carry no warranties and are simply a graphic representation. The best available data depicting the property boundary, critical areas, and buffers is the land survey. The survey map is accurate only to extent of surveying and plotting methods. The survey was based on demarking boundaries using public Title records and professional land surveying techniques. This report was prepared under the assumption that there are no on -going or unresolved land use critical area violations or Cease and Desist orders reported or filed on the project site. This report does not provide detailed analysis of the functions and values of any critical area except qualitatively, as presented in SECTION 13.1.7 (Functions & Values). This report does not provide a detailed impact analysis to determine the potential affect for any proposed development on the functions and values of any critical area. For this report a critical area does not include aquifer recharge zones, erosion prone topography, steep slope designation, historic cultural land use, and geological hazardous areas. The work did not provide a detailed study or assessment beneath any man -influenced fill material or of any topsoil removed and/or disturbed due to previous vegetation clearing, scarifying, dumping, grading, filling, and/or ditching. The work did not include performing detailed study of priority habitat and species, geologic interpretation, engineering, applying or obtaining any permits, performing a professional land survey of critical area edges (done by a client -contracted surveying company), or trespassing onto off -site properties. The work did not determine if a WDNR Forest Practices Application permit is needed for any future tree management, logging, grubbing, and/or clearing activities. Generally a WDNR Forest Practices Application permit is required when greater than 5,000 board feet of merchantable timber is planned for removal. EnCo Wetland - Wildlife - Stream • Shoreline • Priority • Habitat Page 46 Areas that were not accessible due to vicious or dangerous animals, very steep ravines, cliffs, very dense thickets and brambles (i.e. Himalayan blackberry, scotch broom, or other scrub -shrubbery), poisonous plants, and/or secured fences or gates were not assessed. The study was performed on land that was accessible by foot and did not include assessing vegetated areas that were deeply inundated (i.e. greater than 1 foot deep) or steeply sloped greater than 65 percent. 19.0 CONCLUSIONS Wetlands are subject to seasonal and annual variation. Critical area determinations are not final until approved by regulatory agencies and/or local jurisdictions. EnCo does not guarantee acceptance or approval by regulatory agencies or that the planned use of the property will be achieved. Based on the information gathered by EnCo at the indicated locations critical areas were identified on the project site. Field verified project site wetlands and streams are depicted on FIGURE 5. The characteristics of project site wetlands are presented on TABLE 11, the characteristics for streams are presented on TABLE 12, and the characteristics of PHS are presented on TABLE 13.

The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Raring Form —western Washington 2 August2004 version 2 Updated with new WDFW defmibions Oct. 2009 Wetland name or number Classification of Wetland Units in Western Washington Uthe hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple IIIGM classes. In this case, identify which hydrologic criteria in questions 1 7 apply, and go to Question 8. 1. M the water levels in the entire unit usually controlled by tides (i.e. except during floods)? C_ go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classed as a Freshwater Tidal Fringe use the forms for Riverine wetlands If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term `Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. �dwater and surface water runoff' are NOT sources of water to the unit. N go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire weda.nd unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? j N� — go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than I foot deep). 1�i0} go to 5 YES — The wetland class is Slope V Wetland Rating Form —western Washington 3 August 2004 version 2 Updated with new WDFW definitions Oct. 2009 Wetland name or number V 5. Does the entire wetland unit meet all of the following criteria? The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE. The riverine unit can contain depressions that are filled with water when the river is not flooding. O go to 6 YES — The wetland class is Riverine 6. is a entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, rf present, is higher than the interior of the wed an - NO — go to 7 The wetland class epressio an I 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM Classes within the wetland unit bein rated HGM Class to Use in Ratio Slope + Riverine Riverine Slope + Depressional De ressional Slope + Lake-uin a Lake -fringe Depressional + Riverine along stream within boundary Depressional Depressional + Lake -fine ressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next Part of the data sheet you will need to determine the HXdrogeomorphic Class of the wetland bein rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Raring Form — western Washington 2 August 2004 version 2 Updated with new WDFW definitions Oct. 2009 Wetland name or number Classification of Wetland Units in Western Washington If the hydrologic criteria listed in each question do not apply :to the entire unit tieing rated, you probably have a unit with multiple. HGM classes. In thiss case, identify which hydrologic criteria in questions 1-7 apply, and go to Question S. 1. Are -the water levels in the entire unit usually controlled by tides (i.e. except during floods)? 'O go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Rivedne wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomflrphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it C�vundwater and surface water runoff are NOT sources of water to the unit. O go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; �At least 30% of the open water area is deeper than 6.6 ft (2 m)? go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than 1 foot deep). - go to 5 YES — The wetland class is Slope Wetland Rating Form — western Washington 3 August 2004 version 2 Updated with new WDFW definitions Oct. 2009 Wedand name or number 5. Does the entire wetland unit meet all of the following criteria?

NOTE: The rtverine unit can contain depressions that are filled with water when the river a nol f coding. 0- go to 6 YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wedand NO — go to 7 ��- The wetland class is Depressions] 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO — go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90•/o of the total area HGM Classes within the wetland unit bean rated HGMCIass to Use in Ratan Slope + Riverine Riverine Slope + Depressional Pgressional Slo + Lake -fringe Lake-ftinge Depressional + Riverine along stream within boundary Depressional Depressional + Lake -fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

In this case, identify which hydrologic criteria in questions 1-7 apply, and goo to Question & 1.Vtheater levels in the entire unit usually controlled by tides (i.e. except during floods)? to2 YES — the wetland class is Tidal Fringe es, is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the llydrogeornorplue Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and lI estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>90%) of water to it. Groundwater and surface waxer runoff are NOT sources of waxer to the unit. N� go to 3 YES — The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet both of the following criteria? The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (9 ha) in size; At least 309/a of the open water area is deeper than 6.6 ft (2 m)? go to 4 YES — The wetland class is Lake -fringe (Lacustnine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3f1 diameter and less than 1 foot deep).

The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE. The riverine unit can contain depressions that are filled with water when the river is n t flooding. O go to 6 YES — The wetland class is Riverine 6. is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year.

The unit seems to be mainUined by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO —go to 8 YES — The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10/6 or more of the total area of the wetland unit being rated.

If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the Hydrogeomorphic Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept.

SPI Does the wetland unit contain individuals of Priority species listed by the WDFWfor the state? r- o j,w. �n) or 4(tt, -Ak SP4. Does the wetland unit have a local significance in addition to its functions? For example, the wetland has been identified in the Shoreline Master Program, the Critical Areas Ordinance, or in a local management plan as having special significance. To complete the next pgd a the data sheet you will need to determine the ff dro eomor hic Class o the wetland bein rated. The hydrogeomorphic classification groups wetlands into those that function in similar ways. This simplifies the questions needed to answer how well the wetland functions. The Hydrogeomorphic Class of a wetland can be determined using the key below. See p. 24 for more detailed instructions on classifying wetlands. Wetland Rating Form — western Washington 2 August 2004 version 2 Updated with new WDFW definitions Oct. 2009 Wedand name or number Classification of Wetland Units in Western Washington If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. In this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question S. 1. Are the water levels in the entire unit usually controlled by tides (i.e. except during floods)? go to 2 YES — the wetland class is Tidal Fringe If yes, is the salinity of the water during periods of annual low flow below 0.5 ppt {Parts Per thousand)? YES — Freshwater Tidal Fringe NO — Saltwater Tidal Fringe (Estuarine) If your wetland can be classified as a Freshwater Tidal Fringe use the forms for Riverine wetlands. If it is Saltwater Tidal Fringe it is rated as an Estuarine wetland Wetlands that were called estuarine in the first and second editions of the rating system are called Salt Water Tidal Fringe in the I- iydrogeamorph is Classification. Estuarine wetlands were categorized separately in the earlier editions, and this separation is being kept in this revision. To maintain consistency between editions, the term "Estuarine" wetland is kept. Please note, however, that the characteristics that define Category I and II estuarine wetlands have changed (see p. ). 2. The entire wetland unit is flat and precipitation is the only source (>W/o) of water to it. Cjwundwater and surface water runoff are NOT sources of water to the unit. N� go to 3 YES = The wetland class is Flats If your wetland can be classified as a "Flats" wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet bath of the following criteria? —The vegetated part of the wetland is on the shores of a body of permanent open water (without any vegetation on the surface) at least 20 acres (8 ha) in size; At least 30% of the open water area is deeper than 6.6 ft (2 m)? O go to 4 YES — The wetland class is Lake -fringe (Lacustrine Fringe) 4. Does the entire wetland unit meet all of the following criteria? The wetland is on a slope (slope can be very gradual), The water flows through the wetland in one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a Swale without distinct banks. The water leaves the wetland without being impounded? NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3ft diameter and less than i foot deep). 6�090 to 5 YES — The wetland class is Slope Wetland Rating Form— western Washington 3 August2004 version 2 Updated with new WDFW definitions Oct. 2008 r Wetland name or number 5. Does the entire wetland unit meet all of the following criteria? {� The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river The overbank flooding occurs at least once every two years. NOTE .• The riverine unit can contain depressions that are filled with water when the river is N�t� fTnoding. go to d YES — The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if presera; is higher than the ipf C3 nr of the wetland Ngo to 7 YES — The wetland class is Depressional 7. Is the entire wetland unit located in a flat with no obvious depression and no overbank flooding. The unit does not pond surface water more than a few inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO —go to 8 The wetland class is Depressions! 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM clases. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within your wetland. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area.

Kemp, Professional Wetland Scientist #2110 of EnCo Environmental Corporation (EnCo). 2.0 TEST PLOTS The test plots were judgmentally selected to represent plant communities, observed lowest topography, differing soil types, near surface hydrology, and habitat on the project site and on contiguous property ranging from about 100 feet to 800 feet from the property boundary. Generally, sample plots were chosen where the boundary of upland plants start changing to facultative or facultative wet trees in combination with understory shrub and herbaceous plants, where there was evidence of extended standing or pooled surface water, suspect or observed saturated soils to the surface, topographic depressions or flats, or at the edge of streams, watercourses, and drainage ways and at the toe of steep slopes, valleys, or ravines. Test plots were evaluated to determine if shade level or surface hydrologic conditions were contributing to the predominance of facultative or wetter plant species. Laterally oriented test plots were established in upland (non -wetland), wetland, wetland edge, waterbody, and ordinary high water mark communities in order to identify the transition between the critical area and their outer boundaries. Sample plots ranged from a radius or rectangular length of 10 feet to 30 feet depending on the vegetation class, aerial cover, slope, change in habitat, structure, and diversity. The test plots were dug with a trenching shovel with a 1.3 foot long blade. The dimensions of the test plot holes were at least 1.5 feet deep by at least 9 inches wide. A wooden stake with color flag marked was placed at each sample test plot. Each wooden stake was marked using indelible ink and labeled with a discrete test plot number (i.e. Plot -1) and sample date. 3.0 ASSESSMENT METHOD Natural resource maps were reviewed in the office before the site visit (office assessment). These maps included parcel, wetland and stream, shoreline, floodplain, floodway, soil, topography, priority habitat and species, Lidar, elevation, color aerial, and other readily available natural resource maps. The site visit included traversing and EnCo Environmental Corporation Stormwater v Site Assessment • Wetland Y Remediation . Habitat 1 transecting the property to compare environmental conditions to the obtained natural resource maps. Data was obtained and compiled at each plot for land use, slope, vegetation, soil, hydrology, drainage, habitat, and species. In April 2008 the ACOE completed a Western Mountains, Valleys, and Coast Region Regional Supplement that was part of a nationwide effort to address regional wetland characteristics and improve the accuracy and efficiency of wetland delineation procedures. The intent of this Regional Supplement was to bring the Corps Manual up to date with current knowledge and practice in the region and not to change the way wetlands are defined or identified. This Regional Supplement is designed for use the current version of the ACOE Manual (1987) and all subsequent versions. On June 30, 2014, Ecology published an update to the 2004 wetland rating systems for eastern and western Washington. The effective date of the 2014 rating systems will be January 1, 2015. This report therefore followed the 2004 wetland rating methods. Because the project site is not complex and does not exhibit difficult or problematic conditions the Routine Level Wetland Determination method was employed. The level of effort required for the Routine Level Wetland Determinate was Level 3. Level 3 included synthesizing data obtained from reviewing readily available maps, surveys, and/or reports in the office and then using this information to investigate and make the determination in the field. 3.1 Vegetation Boundaries between depressional lows, wetlands, and non -wetlands were established by assessing the transitional gradient between hydrophytic and wetter vegetation to the upland vegetation. In cases where the vegetation was significantly disturbed or removed a visual inspection was performed on property located contiguous to the site. In these cases the undisturbed (or less disturbed) off -site vegetation was used to assist in the hydrophytic vegetation determination on the project site. Observed dominant and non -dominant vegetation species in the test plot and in areas outside the test plot were recorded onto a field data form. Nomenclature of the observed plant species generally followed guidelines in Hitchcock and Cronquist - 2001. A professional botanist was contracted to key out plants which could not be accurately identified. This National Wetland Plant List (NWPL) represents a national effort led by the U.S. Army Corps of Engineers . The NWPL (and the information implied by its wetland plant species status ratings) is used extensively in wetland delineation, wetland restoration and research, and the development of compensatory mitigation goals, as well as in providing general botanical information about wetland plants. The percentage of aerial cover for each species in each plot was estimated within each stratum (emergent/shrub/tree). All species were ranked for dominance based on aerial EnCo Environmental Corporation Stormwater • Site Assessment • Wetland • Remediation a Habitat 2 cover and indicator status within each stratum. Dominant species in each stratum were ranked in decreasing order of abundance and were then cumulatively totaled in each stratum. Dominance in a test plot was established by those plants that exceed 50 percent of the total dominance measured for that stratum, plus any additional plant species comprising 20 percent or more of the total dominance measured for the stratum (no ties). Dominant species were compared to their respective indicator status (USDA — 2012). When more than 50% of the dominant species in the plot had an indicator status of OBL, FACW, and/or FAC, the hydrophytic criteria for vegetation was met. Indicator categories for vegetation status are presented below: Obligate Wetland (OBL): Occur almost always (estimated probability greater than 99%) under natural conditions in wetlands. Facultative Wetland (FACW): Usually occur in wetlands (estimated probability 67% - 99%) but occasionally found in non -wetlands. Facultative (FAC): Equally likely to occur in wetlands or non -wetlands (estimated probability 34% - 66%). Facultative Upland (FACU): Usually occur in non -wetlands (estimated probability 67% - 99%) but occasionally found in wetlands (estimated probability 1 % - 33%). Obligate Upland (UPL): Occur in wetlands in another region but occur almost always (estimated probability >99%) under natural conditions in non -wetlands in the region indicated. If a species does not occur in wetlands in any region, it is not on the National List. 3.2 Soil At least two subsurface soils were collected from each dug hole at each test plot using a long -bladed trenching shovel and a 1-inch diameter, open sided, soil probe or garden spade. Soil samples were evaluated at approximately 2 inches, 6 inches, and from 10 inches to 18 inches below ground surface, depending on soil characteristics, soil layers, hydric soil indicators, root mass (50% of mass) depth, and/or observed moisture. Soil samples were visually compared to the 2009 edition of the Munsell soil color charts. Munsell soil chips are cleaned of soil after each use and changed out after two years of use to prevent color shifting reactions caused by exposure to sun, soils, atmosphere, and water. The observed colors were recorded onto a field data form. Soil color can be used to infer parent material, percent organic content, or soil drainage characteristics. For example, soils with both low chroma and value (10YR, 2, 2) are very dark -colored and tend to have high organic matter contents; soils with a Munsell chroma code of 2 or less (10YR, 7, 2) may be poorly drained. Distinct redox concentrations are an indication that the soil goes through alternating periods of extended soil saturation and drying. EnCo Environmental Corporation Stormwrater u Site Assessment a Wetland • Remediation • Habitat 3 The depth to saturated soils in the test pit will almost always be nearer the ground surface as compared to standing water due to the capillary fringe. For soil saturation to impact vegetation it must occur within a major portion of the root zone of the prevalent vegetation. The major portion of the root zone is that portion of the soil profile in which more than one half of the plant roots occur. Generally soils within one foot of the ground surface were classified as being hydric with an observed matrix chroma of 2 or less than 2 with greater than a few (>2 percent) redox features and with a matrix chroma of 1 or less than 1 in soils with no redox features in the upper part. Other hydric soil indicators were assessed including depleted matrix, gley color, hydrogen sulfide odor, histic epipedon, black histic, depleted below dark surface, thick dark surface, redox dark surface, depleted dark surface, redox depression, organic soil (i.e. Histosols), loamy mucky mineral, loamy gleyed matrix, sandy mucky mineral, sandy gleyed matrix, sandy redox, and sandy stripped matrix. County Natural Resource District hydric soil maps and soil inclusions were also noted. Soil texture describes the relative dominance in size of soil particle smaller than 2 millimeters in diameter. Sand, silt, and clay are the three size classes with sand being the largest size and clay being the smallest. The textural names are applied based on the weight percentage of sand (S), silt (Si), and clay (C). The estimated percent of sand, silt, and clay are noted with the textural name. Mottling (redox) indicates the evidence of slow vertical movement of surface water through the upper low permeable loams to the top of a till layer (if present) and long duration of saturation. Due to the very dense and cemented nature of till zones, percolated water can be impeded and can flow laterally across the top of the till. Mottling usually occurs near the transition zone between the upper soil layers and till. 3.3 Hydrology Examples of wetland hydrology indicators include presence of surface water, high water table, saturation, water marks, sediment deposits, drift deposits, algae mat/crust, iron deposits, organic encrustations, salt crust, surface soil cracks, sparsely vegetated concave surface, aquatic invertebrates, hydrogen sulfide odor, oxidized rhizospheres, reduced iron, iron reduction in tilled soils, stunted/stressed plants, water stained leaves, drainage patterns, dry -season water table, geomorphic position, shallow aquitard, raised ant mounds, aquatic invertebrates, inundation (imagery) and frost -heaved hummocks. The observed wetland hydrology indicators, if any, were recorded onto a field data form. Wetland hydrology is determined based on an "average year" of wetness that prevails in most years. Extended wetness occurring in most years is defined as roughly every other year. This definition for average year wetness has been the standard for wetland delineation methods. EnCo Environmental Corporation Stormwater a Site Assessment • Wetland a Remediation a Habitat 4 Saturation within at least 50 percent of the root zone is fundamental for defining wetland hydrology. Generally, the majority of the roots in wetland herbs occur within the upper 6 inches and in woody plants within the upper 6 inches to 18 inches. The percentage of slope in each wetland was measured in the field using one of three methods: 1. Interpreting elevation contours from local USGS topographic maps and/or other elevation contour maps 2. Visual estimation 3. Using an electronic inclinometer, Model/Type 86 4. Referring to a recent professional survey with elevations 4.0 WETLAND & WATER DETERMINATION The work entailed assessing all three wetland characteristics; dominant hydrophytic vegetation, hydric soil, and wetland hydrology. Equal emphasis was placed on all three criteria: vegetation, soil, and hydrology because all three of these criteria were easily identified. If equal emphasis was not employed the explanation for this is presented in the report. If all three wetland parameters were present or reasonably inferred under normal circumstances, a positive wetland determination was made for that test plot. If any one or more of the three parameters was not wetland in character the area was considered upland (non -wetland) unless the area was determined to be abnormal, significantly disturbed, atypical, assumed, problematic, or artificial. Abnormal, atypical, problematic, or significantly disturbed areas may include situations where field indicators of one or more of the three wetlands identification criteria are obliterated or not present due to recent change in land use or from other difficult situations. A decision as to whether or not the assessed area is abnormal, significantly disturbed, atypical, or problematic was made and recorded after review of aerial photographs, surface and subsurface soil characteristics, hydrologic conditions, Soil Conservation Service soil manuals, wetland atlases, wetland inventory maps, and/or local site conditions in the near vicinity of the area. Artificial wetland areas may or may not be jurisdictional according to state or local regulations. A determination was made in the field by observing suspect artificial features such as test pits, road ruts, irrigation canals, drainage ditches, dikes, dams, swales, lagoons, false ponds, mined areas, and other man-made landscape features. Water determinations were made using Washington Department of Natural Resources (WDNR) water type guidelines, 2002, amended in 2006. EnCo Environmental Corporation Stormwater s Site Assessment 7 Wetland a Remediation • Habitat 5 5.0 PRIORITY HABITAT & SPECIES DETERMINATION The presence or absence of PHS was made by performing a cursory habitat assessment. The field assessment included documenting observed sightings, vocalizations, field indicators, or other evidence. The determination for presence or absence of PHS is based on the time and date in the field and did not reflect diurnal or seasonal variances. Priority and sensitive habitats and priority species determinations were also made using Washington Department of Fish & Wildlife (WDFW) information, and publically available maps. The PHS on the Web is a WDFW web -based, interactive map developed for citizens, landowners, cities and counties, tribal governments, other agencies, developers, conservation groups, and interested parties to find basic information about the known location of PHS. PHS is a source of best available science that informs local planning activities, development projects, conservation strategies, incentive programs, and numerous other land use applications. The PHS on the Web map displays known locations of priority habitats and species that have been provided to the department by agency biologists and other sources of scientific data about species and habitat locations. Data is updated as new information is gathered and verified in the field. This map is not an exhaustive survey of all fish and wildlife presence. 6.0 DIAGRAM The sample test plots, wetland edge, stream edge, shoreline edge, ordinary high water mark, floodway, observed presence or indicators of priority and sensitive habitats and species, and standard buffers were mapped "to -scale" on a diagram by a professional land surveyor. The method employed is accurate only to the degree permitted by the implied plotting, measuring, or surveying methods.

Wetland categories and standard buffers. Structures, improvements and land surface modifications within regulated wetlands. Structures, improvements and land surface modification within regulated wetland buffers. 19.175.010 Determination of wetland and regulated wetland. (1) Generally. The March 1997 Washington State Wetlands Identification and Delineation Manual (Department of Ecology Publication No. 96-94) as set forth in WAC 173-22-080, as it exists as of November 1, 1999, or as subsequently amended, will be used for identification and delineation of wetlands within the city. Although a site -specific wetland may not meet the criteria described above, it will be considered a regulated wetland if it is functionally related to another wetland that meets the criteria. Where vegetation has been removed, a wetland may be determined by the presence of hydric soils, as well as other documentation of the previous existence of wetland vegetation such as aerial photographs. (2) Evaluation. If the city determines that a wetland may exist on or within 200 feet of the subject property, the director shall require the applicant to submit a wetland report, prepared by a qualified professional approved by the city, that includes the information set forth in subsections (2)(a) through (g) and (3) of this section. The director shall use the information required by subsections (2)(a) and (b) of this section to determine if the area is a regulated wetland and, if so, shall use the information required by subsections (2)(c) through (g) and (3) of this section to determine the category and the precise boundaries of that regulated wetland. (a) An evaluation of whether the area in question is a regulated wetland under this section, FWRC and the definition of "wetland" in FWRC (b) An overview of the methodology used to conduct the study. (c) A description of the wetland and plant communities found therein, a map delineating the edge of the wetland and location of plant communities, and a detailed description of the method used to identify the wetland edge. (d) The wetland classification, according to the U.S. Fish and Wildlife Service "Classification of Wetlands and Deep Water Habitats in the U.S." (a) A list of observed plant and wildlife species, using both scientific and common names, and a description of their relative abundance. (f) A list of potential plant or animal species based on signs or other observation. (g) An evaluation and assessment of the existing or potential functions and values of the wetland based on the following factors: surface water control; wildlife habitat; pollution and erosion control; groundwater exchange; open space and recreation; and educational and cultural opportunities. (3) Drainage facilities. Surface water ponds, drainage ditches, and other such facilities which were designed to impound or convey water for an engineered purpose are not considered regulated wetlands under this division provided they meet all of the following criteria (a) The drainage facility must have been intentionally human -created. This is to differentiate from those wetland sites that are accidental consequences of development actions, such as road construction or culvert placement. Such sites may be considered regulated wetlands by the director upon a review, under subsection (2)(9) of this section, of the ecological functions and values of the site. (b) The drainage facility must have been originally constructed on uplands (nonwetland areas). If the drainage facility is located within a straightened, channelized, or otherwise disturbed natural watercourse, it may be considered a regulated wetland by the director upon a review, under subsection (2)(g) of this section, of the ecological functions and values of the site. (c) The facility must be actively operated as a surface water drainage facility. Abandoned drainage facilities may be considered regulated wetlands by the director upon a review, under subsection (2)(g) of this section, of the ecological functions and values of the site. (d) Wetland conditions have not expanded beyond the originally constructed drainage facility boundary. In such a case, the expanded area may be considered a regulated wetland by the director upon review, under subsection (2)(g) of this section, of the ecological functions and values of the site. (e) The drainage facility was not designed or constructed as a requirement to mitigate previous wetland impacts. (f) The director finds that limited ecological functions and values do not warrant application of the city's wetland regulations. (Ord. No. 09-593, § 31, 14-09; Ord. No. 07-554, § 5(Exh.

(1) Regulated wetlands are classified into the following categories: (a) Category I wetlands meet one of the following criteria: (1) Contain the presence of species or documented habitat recognized by state or federal agencies as endangered, threatened or potentially extirpated plant, fish or animal species; or (ii) Contain the presence of plant associations of infrequent occurrence, irreplaceable ecological functions, or exceptional local significance including but not limited to estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange areas, significant habitat or unique educational sites; or (iii) Have three or more wetland classes, one of which is open water. (b) Category II wetlands are greater than 2,500 square feet in area, do not exhibit the characteristics of Category I wetlands, and meet one of the following criteria: (i) Are contiguous with water bodies or tributaries to water bodies which under normal circumstances contain or support a fish population, including streams where flow is intermittent; or (ii) Are greater than one acre in size in its entirety; or (iii) Are less than or equal to one acre in size in its entirety and have two or more wetland classes, with neither class dominated by nonnative invasive species. (c) Category III wetlands are greater than 2,500 square feet in area and do not exhibit those characteristics- of Category I or II wetlands. (2) Standard buffer widths for regulated wetlands are established as follows: (a) Category I wetlands shall have a standard buffer width of 200 feet. (b) Category 11 wetlands shall have a standard buffer width of 100 feet. (c) Category III wetlands shall have a standard buffer width of 50 feet for wetlands that are greater than 10,000 square feet in area, and shall have a standard buffer width of 25 feet for wetlands that are between 2,500 to 10,000 square feet in area.

(b) The stream setback area for a minor stream includes all areas within 50 feet outward from the ordinary high water mark of a minor stream. (2) The stream setback areas established by this section do not apply to any segment of a stream that is presently within a culvert, unless that stream will be taken out of the culvert as part of development of the subject property. (Ord. No. 1-1-705, § 5 (a—h. B), 11-1-11. ) (1) Relocation of a stream on the subject property is permitted subject to all of the conditions and restrictions of this section. (2) A proposal to relocate a stream will be reviewed and decided upon using Process IV per Chapter FWRC.

B), 11-I-1 i.j Article ill. Regulated Wetlands (1) Generally. The March 1997 Washington State Wetlands Identification and Delineation Manual (Department of Ecology Publication No. 96-94) as set forth in WAC 173-22-080. as it exists as of November 1, 1999, or as subsequently amended, will be used for identification and delineation of wetlands within thc: city. Although a site -specific wetland may riot meet the criteria described above, it will be considered a regulated wetland if it is functionally related to another welland that meets the criteria. Where vegetation has been removed, a wetland may be determined by the presence of hydric soils, as well as other documentation of the previous existence of wetland vegetation such as aerial photographs. (2) Evafuafion. If the city determines that a Weiland may exist on or within 200 feel of the subject property, the shoreline administrator shall require the applicant to submit a wetland report, prepared by a qualified professional approved by the city, that includes [lie information set forth in subsections (2)(a) through (g) and (3) of this section. The shoreline administrator shall use the information required by subsections (2)(a) and (b) of this section to determine if the area is a regulated wetland and, if so, shall use the information required by subsections (2)(c) through (g) and (3) of this section to determine the category and the precise boundaries of that regulated wetland. (a) An evaluation of whether the area in question is a regulated wetland based upon the definition of a wetland and the size thresholds outlined in FVVRC (b) An overview of the methodology used to conduct the study. (c) A description of the wetland and plant communities found therein, a map delineating the edge of the wetland and location of plant communities, and a detailed description of the method used to identify the welland edge. (d) The wetland classllication, according to tilt: U.S. Fish and Wildlife Service "Classification of Wetlands and Deep Water Habitats in tilt. U.S." (e) A list of observed plant and wildlife 5pCCi(- S, LlSlllg both scientific and common nE.mes, and a description of their relative abundance. (f) A list of potential plant or animal species based on signs or other observation- (g) An evaluation and assessment of the existing or potential functions and values of the vvetland based on the following factors. surface water control; wildlife habitat; pollLrliorr and erosion control; groundwater exchange; open space and recreation; and educational and cultural opportunities. (3) Drainage facilities. Surface b'Jalei' ponds, drainage ditches, and other such facilities w lik;h were designed to impound or convey water for an engineerLd purpose are: not considered regulated wetlands under this chapter, provided they meet all of the following crile0a: (a) The drainage facility must have been intentionally human created. This is to differentiate from those wetland sites that are accidental consequences of development actions, such as road construction or culvert placement. Such sites may be considered regulated wetlands by the director upon a review, under subsection (2)(g) of this section, of the ecological functions and values of the site. (b) The drainage facility 111LISI have been originally constructed on uplands (nonwedand areas). If the drainage facility is located within a straightened. c:hannelized, or othervvise disturbed natural watercourse, it may be considered a regulated wetland by the director upon a review, under subsection (2)(g) of Oils section, of the ecological functions and values of the site. (c) The facility must be actively operated as a surface water drainage facility. Abandoned drainage facilities may be considered regulated wellands by the director upon a review, under subsection (2)(g) of this section, of the ecological functions and values of the site. (d) Welland conditions have not e paraded beyond the originally constructed drainage facility boundary. In such a case, the expanded area nlay be considered a regulated wetland by the director upon review, under subsection (2)(g) of this section, of the ecological tunclions and values of the site. (e) The drainage facility %,vas not designed or constructed as a requirement to mitigate previous wetland impacts. (f) The director finds that limited ecological functions and values do not warrant application of the city's wetland regulations. (Ord No 11-705, § 5 (Exh. B), 11-1-11.) (-I) Wetlands are classified into the following categories: (a) Category I wetlands meet one of the following criteria: (i) Contain the presence of species or documented habitat recognized by state or federal agencies as endangered, threatened, or potentially extirpated plant. fish, or animal species; or (ii) Contain the presence of plant associations of infrequent occurrence, irreplzceable ecological functions, or exceptional local significance including but not limited to estuarine systems, peat bogs and fens, mature forested wetlands, groundwater exchange areas, significant habitat, or unique educational sites; or (iii) Have three or more wetland classes, one of which is open water. (b) Calegory Il wetlands are greater than 2,500 square feet in area, do not exhibit the characteristics of Category I wetlands, and meet one of the following criteria: (i) Are contiguous with water bodies or tributaries to water bodies which under normal circumstances contain or support a fish population, including streams where flow is intermittent; or (ii) Are greater than one acre in size in their entirety; or (iii) Are less than or equal to one acre in size in their emir ety and have two or more wetland classes, with neither class dominated by nonnative invasive species. (c) Category III wetlands are greater than 2,500 square feet in area and do not exhibit those characteristics of Category I or II wetlands. (2) Standard buffer widths for regulated wetlands are established as follows: (a) Category I wetlands shall have a standard buffer width of 200 feet. (b) Category II ,,Ajetlands shall have a standard buffer Widih of 100 feet. (c) Category III wellands shall IlitVe a SlRrldard bLI[1e1- a,rlclth of 50 feel fot wetlands that are greater than 10,000 square feet in area, and shall have r, standard buffer width of 25 feel for wetlands that are between 2,500 to 10,000 square feet in area. (Ord. Mo. 1-I-705, § 5 (Exhl 13), "I1-1-1-1.) ( I ) Generally. No clearing and grading may lake place and no structure or improvement muy be located in a regulated wetland except. as provided in this section. (2) ;'wblic park. The city may allow pedeshian access through a regulated Welland in conjunction with a public ljark. The access, if approved, must be designed to the maXinlUrn extent feasible to protect the welland from any adverse effects or impacts of the access and to limit the access to the defined access area. (3) Rehabilitation The shoreline administrator may permit or require an applicant to rehabilitate and maintain a regulated wetland by removing detrimental material such as debris and inappropriate vegetation and by requiring that native vegetation be planted.-ftrese actions may be required at any time that a condition detrimental to water quality or habitat exists. (.1) A4cidificaiion. Other than as specified in subsections (2) and (3) of this section, the city may approve any request to locate an iniprovenir:nt or engage in clearing and grading within a regulated vielland using Process lV per Chapter FVVRC. "file specific location and extent of the intrusion into [lie regulated wetland must constitute the minimum necessary encroachment. Approval of a request for improvements or clearing and grading within a regulated wetland through Process IV of FVVRC Title shall be based on the following criteria. (a) It will not adversely affect water quality. (b) It will not adversely affect the existing quality of the vielland's or buffer's wildlife habitat. (c) It will not adversely affeci drainage or stonlnvaler retention capabilities. (d) It will not lead to unstable earth conditions nor create erosion hazards. (e) It will not be materially detrimental to any other propel ty in the area of the subject property nor to the city as a whole, including the loss of open space. 9/16/2014 History: Weather Underground Sunday Monday 11 Tuesday Wednesday Thursday Friday Saturday I 2 3 4 5 7 Actual: 72151 Actual: 7., 52 Actual: 65152 Actual: 67150 Actual: 72150 Actual: 77 151 Actual: 76156 Precip: 0.00 Precip: 0.00 Precip: 0.00 Precip: 0.00 Precip: 0.00 Precip: 0.00 Precip: 0.00 Average-G-11 50 Average: 150 Average-6.9 150 Average;GEI 1 50 Average:68 1 51 AWerage:68 51 Average:613 1 51 Precip: 0.07 Precip: 0.06 Precip: 0.06 Precip: 0.07 Precip: 0.06 Precip: 0.06 Precip: 0.06 8 10 11 14 Actual: 74 1 54 Actual: 70 i 56 Actual: GS 154 Actual: 75 1 52 Actual: 71 1 54 Actual: 60 i 52 Actual: 64 153 Precip: 0.00 Precip: T Precip: 0.00 Precip: 0.00 Precip: 0.07 Precip: 0.25 Precip: 0.00 Aaerage:69151 Average:69151 Average:69151 Average:691 51 Average:69151 Auerage:,59 1 52 Average:70152 Precip: 0.07 Precip: 0.06 Precip: 0.06 Precip: 0.06 Precip: 0.06 Precip: 0.05 Precip: 0.06 I5 16 '17 18 19 20 21 Actual: ii., 1 50 Actual: 64 148 Actual: 64 1 50 Actual: 66 1 52 Actual: 78 i 53 Actual: 68 50 Actual: 72 1 51 Precip: 0.02 Precip: 0.14 Precip: 0.05 Precip: 0.00 Precip: 0.03 Precip: 0.01 Precip: 0.00 Average:70 1 52 Average:70 1 52 Average:70 152 Average:70 1 52 Average:70 1 52 Average:71 1 53 Average:71 i 53 Precip: 0.05 Precip: 0.06 Precip: 0.05 Precip: 0.05 Precip: 0.05 Precip: 0.05 Precip: 0.05 22 23 24 25 26 27 28 Actual: 77 1 52 Actual: 77 56 Actual: ?6 158 Actual: 79 1 57 Actual: 70 58 Actual: 70 57 Actual: 63 5G Precip: 0.00 Precip: T Precip: 0.00 Precip: 0.00 Precip: T Precip: 0.07 Precip: 0.09 Avorage:71 1 53 Average:71 53 Average:72 53 Average: 721 53 Ave rage:72 53 Aierage:72.1 53 Average:73 54 Precip: 0.04 Precip: 0.04 Precip: 0.05 Precip: 0.04 Precip: 0.03 11 Precip: 0.04 Precip: 0.04 29 3U Actual: 69 55 Actual: 78 55 Precip: T Precip: 0.00 Average-.73 54 Average:731 54 Precip: 0.03 Precip: 0.04 Mnnlh PrecIp!tatlan -Actual month total: 0.73Nam7a& mount Ialal: 1.57 Calendar Key Data Cat&aory Mostly TLCOndition Actual' a 7emmp p• Sunny Cloudy Mostly Sunny Cloudy Rain Snow PI'E?CI 4.�� Precip.

King County C King County 2014 Privacy Accessibility Terms of use Env(ronmental Corporation APPENDIX F TERMS & CONDITIONS EnCo Stormwater • Site Assessment • Wetland • Remediation • Habitat POB 1212 Puyallup WA 98371 Telephone: 253.841.9710 www.encGec.com Environmental Corporation TERMS AND CONDITIONS WETLAND, STREAM, WATER & PRIORITY HABITAT AND SPECIES The intent of the completed report was to address the requirement for a wetland delineation, category rating, stream type classification, wetland and stream standard buffer width determination, and a limited priority habitat and species assessment with recommended buffer width based on the described methods as defined in the attached report. The information presented in the report reflects the best professional opinion regarding the conditions studied and observed on the project site at the time and date the field work was performed. The work did not include determining detailed wetland function and values, completing permit applications, attending meetings with the client or regulatory officials (except for the client meeting when in the field and one meeting at the project engineer's office), preparing a wetland or wetland buffer mitigation plan, performing detailed habitat or biological analysis, significant tree surveys, endangered species studies, erosion and sedimentation assessments, engineering, pollutant impacts, stormwater drainage, and/or geotechnical or geologic hazards or impacts. The jurisdictional government agency has the final authority to approve or disapprove the identified critical area edges, standard buffer widths, wetland rating scores, wetland categories, stream classifications, modified buffer widths (if any), building setbacks, land use intensity, and exemptions. The regulations applicable to wetlands and streams are subject to varying interpretations and will change over time by municipalities, counties, or state government. The proposed change in land use will be reviewed at the time of plat submittal. A project may vest to the current code with site specific conditions that will need to be completed prior to obtaining plat approval. This report is intended to provide information deemed relevant in the applicant's attempt to comply with the critical area laws and regulations now in effect. It will be the responsibility of the project engineer or developer to determine the land use density / intensity prior to having EnCo determine the standard buffer widths. The work employed using professional and technical judgment in accordance with the degree of care and skill generally accepted in the nature of the work accomplished within the constraints of time, budget, and the defined SCOPE OF WORK. The priority habitat and priority species assessment was limited to a cursory field inspection in combination with interpretation of documents and maps available at WDFW and WDNR. Readily available public data and maps were reviewed "as -is" and "with all faults". EnCo disclaims any warranty of merchantability or warranty of fitness of the obtained data or map for any particular purpose, either expressed or implied. No representation or warranty is made concerning the accuracy, reliability or timeliness of the data or maps. Any user of the data or maps assumes all responsibility for use thereof, and further agrees to hold the government agency and EnCo harmless from and against any damage, loss or liability arising from any use of these data or maps. The work was performed based on the understanding and interpretation of the local, state, and federal regulations and site conditions at the time of the field work. The final wetland, stream, and other waterbody edges and buffer boundary determinations and classifications and/or categories must be verified and approved by the local jurisdiction prior to any disturbance and development. The information and conclusions presented in the report may need to be revised based on comments from the jurisdictional agencies or due to unforeseen changes in lot layout by the developer or engineer. Wetlands, streams, other waterbodies, habitats, and species use are considered dynamic communities and will change over time. Past and present conditions, which cannot be observed, were established on the basis of reviewing reasonably ascertainable records, maps, photographs, documents, and/or information provided by federal, state, and/or local agencies and contacted individuals. EnCo can not attest to the validity, completeness, or accuracy of these documents or personal accounts. Many of the maps and diagrams presented in this report are in color. Black and white copies made from these color maps and diagrams will remove the distinctions between certain boundaries. Items provided by the client included the right of entry (verbally or by a contract) onto the project site and in some cases on adjoining properties prior to conducting the work. The project site boundaries were clearly marked or determined by the client or landowner representative prior the fieldwork. A professional land survey of the delineated critical areas was performed by others. The EnCo report is for the exclusive use of our client and their assigns. Any other parties that would wish to use the report shall notify EnCo in writing and shall obtain a Reliance Letter. A separate fee will be charged for preparing a Reliance Letter.
