Lot Si.Ze —The zoninR for the subject site is RS-35.0. Minimum lot size for each lot is 35,000 square feet. As depicted, the proposed lots meet the minimum lot size requirement. Property dedicated to the city for right-of-way frontage improvements may not be counted in lot areas (see the Traffic comments). Property set aside in tracts (access, critical -area, and/or open space) cannot count towards the minimum lot area per FWRC 19.05.120 "lot area" and 19.145.150.1. Also, all residential subdivisions are required to provide open space in the amount of 15 percent of the gross land area of the subdivision site per FWRC 18.55.060(2). If open space is provided onsite, it shall be provided in its own tract, see item #10, below. 8. Setbacks— Future residences must conform to the following structural setback requirements of FWRC 19.200.010, "Detached Dwelling Units": front yard — 20 feet; side yard — 10 feet; and rear yard — 10 feet. Existing structures to be retained must conform to the structural setback requirements from newly located property lines. 9. Mitrellaneous Sing le -Family y Residential Re ,gulations — a. Maximum height of structures — 30 feet above average building elevation. b. Maximum lot coverage — 50 percent. c. Required parking spaces — two per dwelling unit. 10. Open Space — YR residential subdivisions are required to provide -open space in the amount of 15 percent of the gross land area of the subdivision site per FWRC 18.55.060(2). All or some of the open space requirement may be satisfied by a fee -in -lieu payment at the discretion of the Parks Director, after consideration of the city's overall park plan, quality, location, and service area of the open space that would otherwise be provided with the project. Open space fees shall be paid prior to recording the short plat. If the applicant chooses to provide onsite open space, it shall be provided in its own tract and include a combination of the following types: Open Space Categoryx� % of Gross Land Area I — -- - ---------- . ..... — ------------- -- - - --------------- Conservation No maximum or minimurn - ----- - ---------------- Per FVVRC 18.55.060.5, "Open space shall be owned in common undivided interest by all property owners wid-iin the land division as members...." As with other tracts, an open space tract cannot count towards the minimum lot area of either lot. Another option related to providing the required open space on -site is to request a modification to die the Parks Director. For example, as part of the short plat an applicant could submit a request to modify the open space category requirements to: 1) not provide the minimum of 10% of "usable" open space; and -9) alloNv the designation of the entire required 15 percent as "conservation" open space to overlay all or a portion critical area as a tract in the short plat. Ffle#B-104380-00-PC D., M 70703 Mr. Evan Mann Page 5 September 28, 2015 11. Clearing, Grading, and Tree and Vegetation Retention — The short plat is subject to the provisions of FWRC 19.120, "Clearing, Grading, and Tree and Vegetation Retention." It is recommended that FWRC 19.120 be reviewed carefully in reference to the proposed short plat. A clearing and grading plan that meets FWRC 19.120.020 and FWRC 19.120.040 must be submitted with the formal short plat application, as clearing and grading work is proposed. 12. Tree Densily Requirements — The plat will be subject to tree density requirements of FWRC 19.120..130(1); note that 25 tree -units per acre are required for single-family zoned sites. A tree unit is a value assigned to existing trees retained on the property or replacement trees. The larger the treerthe greater value it is assigned. Required tree density can be composed of retained trees and replacement plantings per FWRC ,19.120.130. The tree and vegetation plan must dearly show where the tree units are to be located. The formal application must indicate what trees are to be removed. In the case of the 14.95-acre site, approximately 374 tree units are required (295 x 14.95 = 374). Tree unit credits are in Table 2 of F"RC 19.120.130-2. The required number of tree units would likely be less than 374, given 1 WRC.19.120,430.3. Under that code section, the total number of tree, units required to be provided is calculated by multiplying gross site acreage, minus any proposed public or private streets and regulated critical areas (excluding buffers). Despite this provision, trees located within critical area buffers shall be credited towards satisfying the tree units per acre requirement. If an applicant cannot provide for the minimum tree units per acre on site, off -site mitigation, or fee -in - lieu payment to the city's urban forestry account, may be approved by the director. See FWRC 19.120;140 for off -site mitigation and fee -in -lieu payment requirements. 13. 11yetlandr — Wetlands exist on and adjacent to the subject property. A report prepared in conformance with the Critical, Areas Ordinance contained in M)VRC 19.145.410 is required.11e, wedand and buffer must be delineated on the short plat drawing and placed in a tract in conformance with FWRC 19.145.150 and 19.145.420. Per FWRC 19.145.420.6, all lots approved in a recorded subdivision that contain wetlands and their associated buffer in a native growth protection casement or tract may be improved pursuant to easement or tract boundaries established in the plat, regardless of subsequent regulatory buffer increases or natural migration. New finpiov6nients shb*4 on the s4W Oat Orawirq�uithui wetl2nd buffers wowduot be approved "is part of the short plat. A separate Use Pi6ctssi 111 appli(atitifi� subtnittal And approval for w4and buffer alterations or reductions is required. The applications can be processed together. FWRC 19.145.440 addresses development within wetland buffers. The applicant must demonstrate the &-improvements to the existing driveway access off of 8th Avenue South (paving and widening to meet city code requirements) and work to upgrade the existing well as detailed in FWRC 19.145.440. The applicant must justify using the existing driveway for the access to the newly created lots rather than locating access in a different portion of the site outside the buffer. 14. r — A portion of the 1�6os is located on Aie subject pjoporty� 1his feature must be delineated on the diort Plat drawiftg and placed 'in a tract in conk6hitice with FWRC1 %145,150 afid 19.145260.

The pond on site is not exempt per C 19.145.110.3. 15. Geo*44g� Ha.Zardous Areas — The short plat drawing shows areas with existing slopes greater than 15%. A professionally prepared geotechnical report is required as part of the application submittal per F­\VRC 19.145.250. All development activities on or within 50 feet of a geologic ally hazardous area as defined in FWRC 19.05.070 are subject to the Critical A -teas Ordinance, see FWRC 19.145.220. All landslide hazard areas and buffers (if any) must be delineated on the short plat drawing and placed in a tract in conformance with F\VRC 19.145.150 and 19.145.230. 16. GificalAresA6" &Ope applicant is responsible for providing critical areas reports to the city and for covering the cost of the city's consultants who may review the reports. The city has a Critical Areas Review Optional Direct Services Program, which provides another option for obtaining the services of a qualified consultant (see enclosed handout). 17. School Impact Fees— School impact fees (currently $5,429.55 per single-family home) are due at the time of building permit application for new dwelling units. This fee amount is subject to change as determined annually by the Federal Way School District. 18. Senage Dis posal— The applicant must provide documentation that each lot in the subdivision will either connect to the sanitary sewer system or provide an on -site septic system. Wherever feasible, all lots in th(6 short plat shall be connected to sanitary sewer system; see comments from Lakehaven Utility District below. If connection to the sanitary sewer system is not feasible, on -site sewage disposal may be utilized. The city does not have any code provision requiring connection to the sanitary sewer system. The design and construction of the septic system must be approved by the Public HeaRli-Seattle & King County. Provide a copy of their Subdivision Pre -Application Report. If on -site septic systems are provided, prior to short plat recording, the applicant must obtain the Public Health -Seattle & King County signature on the short plat document and provide a copy of their signed Application for Final Subdivision. 19. Approval Duratiog — Short plat prelmainary approval expires five years from the date of approval - Engineering plans must be approved, improvements constructed, and the short plat must be recorded within the five-year time period. No less than 60 days prior to the lapse of approval, the applicant may request a two-year time extension for the short plat approval. 20. Recordin ,g — The city will record the short plat with the King County Division of Records and Elections subsequent to the Public Works Department approval of submitted as -built plans. Prior to recording the short plat, all surveying and monumentation, must be complete. In addition, all other required improvements must be substantially completed as determined by the departments of Community Development and Public Works.

At the time of land use site plan preliminary short plat submittal, a preliminary Technical Information Report (TIR), addressing the relevance, of die project to the eight core and five special requirements of the K_CSNVD1V1 will be required. A Level 1 downstream analysis shall also be provided in the preliminary TM. The city has 1" = 100', five-foot contour planimetric maps that may be used for basin analysis. 2. The project lies within a Conservation flow control area; thus, the applicant must design the flow control facility to meet these performance criteria. In addition to flow. control facilities, Best Management Practices (BMP's) are required as outlined in the KCSM. The project also lies within an Enhanced, Basic Water Quality Area. Water quality treatment shall be designed to meet the treatment criter ia.of the Enhanced Basic Water Quality Menu. 3. If infiltration is proposed, soil logs prepared by a licensed geotechnical engineer or septic de I sigtier=st be provided to verify infiltration suitability.- 4. Detention and water quality facilities for short plats must be above ground (i.e. open pond). Underground facilities are allowed only with approval from the Public Works Department: 5. Show the proposed location and dimensions of the detention and water quality facilities on the preliminary plans. 6. If more than one acre vill be disturbed during construction, a National Polhatant Discharge Elimination' System (NPDES) construction storm water permit may be required.

Seethe Traffic Division comments from Senior Transportation Planning Engineer Sarady Long for traffic related items. 2. If dedication of additional right-of-way is required to install street frontage improvements, the dedication shall be conveyed to the city through a statutory warranty deed. The dedicated area must have clear tide prior to recording. 3. All storinwater treatment and detention requirements outlined above may apply to any improvements thin the public right-of-way. 4. FVVRC 19.135.280 requires that driveways serving residential uses may not be located closer than 25 feet to any street intersection. Lots and intersections within new subdivisions or short plats must be designed to meet this standard. File 415-104380-00-PC D­ ID 70703 Mr. Evan TVann Page 8 September 28, 2015 1. Engineered plans are required for clearing, grading, road construction, and utility work. Plans must be reviewed and approved by the city. Engi incering review fees are $824.50 for the first 12 hours of review, and $68.00 per hour for additional review time. A final TIR shall be prepared for the project and submitted with the engineermiz plans. Both the TIR and the plans will re i the signature seal of a quire professional engineer registefed/licensed in the State of Washington. 2. In addition to engineering approval, short plats and subdivisions are required to obtain a separate permit for grading. Details and fees may be obtained from the Building Division. 3. The Federal Way Public Works Development Standards Manual (standard detail drawings, standard notes, and engineering checklists) is available on the city's website, to assist the applicant's engineer in preparing the plans and TIR. 4. Bonding is required for all street improvements and temporary erosion and sediment control measures associated -wit� the project. The bond amount shall be 120 percent of the estimated costs of the improvements. An administrative fee deposit will need to accompany the bond to cover. any possible legal fees in the event the bond must be called. Upon completion of the installation of the improvements, and final approval of the Public Works Inspector, the bond will be reduced to 30 percent of the original amount and held for a two-year maintenance period. The developer will be responsible for the maintenance of all storm drainage facilities (including the that time, the Public Works Inspector will make periodic visits to the site to ensure the developer's compliance with the maintenance requirements. Upon satisfactory completion of the two-year maintenance period, the remainder of the bond will be released. Maintenance for public roads and subdivision drainage facilities then become the responsibility of the city. Maintenance for private roads zed dra4age 9.cilities- including short Dlats- remain the resDonsibilitv of the individual t)rot)ertv owners. 6. When topographic survey information is shown on the plans, the vertical datum block shall include the phrase "DATUM: N.G.V.D.-29" or "DATUM: K.C.A.S.," on all sheets where vertical elevations are called out. 7. Drawings submitted for plan review shall be printed on 24" x 36" or 22" x 34" paper. Site plans shall be drawn at a scale of 1" = 20', or larger. Architectural scales are not permitted on engineering plans. 8. Provide cut and fill quantities on the clearing and grading plan. 9. Temporary Erosion and Sediment -control (TESL) measures, per Appendix D of the 2009 KCSWDM, must be shown on the engineering plans. 10. The site plan shall show the location of any existing and proposed utilities in the areas affected by construction. File # 15- 1 04380-00-PC Doc ID 70703 Mr. Evan Mann Page 10 September 28, 2015 Eighth Avenue South is planned as a Type "T" street, consisting of a 28-foot street with an 8-foot ditch, 5-foot sidewalks and street lights in a 60-foot right-of-way. Assuming a symmetrical cross section, half street n'nprovements are required as measured from the street centerline. At a minimum, the improvement shall include a 20-foot street with an 8- foot ditch, 5-foot sidewalk and street lights. It appears the existing right-of-way would be adequate to accommodate the adopted cross section. 2. The applicant may make a written request to the Public Works Director to modify, defer, or waive the required street improvements (FWRC 19.135.070). Information about a right-of-way modification requests are available through the Public Works Development Services Division. Please note that these modification requests have a nominal review fee currently at $105.90. 3. Tapers and transitions beyond the project frontage may be required as deemed necessary for safety purposes; taper rate shall be WS^2/60 or as directed by the Public Works Director. Access Management (FWRC 19.135) L WAC 468-52-040 limits access on state highways to access spacing of 250 feet with only one access per parcel. Pacific Highway South is access class "l" where left access maybe permi'tted every 330 feet and left -out access is only permitted at signalized intersections (F\VRC 19.135.280). Furthermore, residential lots should not have access onto arterial streets per FVvTRC 18.55.020. However, it appears that the applicant is not proposing to modify the existing driveway on SR 99, which is currently serving one lot. This is acceptable. 2. Please provide photo documentation within the appendix of the sight distance analysis. A minimum of one photo looking to the left and one looking to the right show the location of the viewer in accordance to AASHTO guidelines. The site plan with plan and profile sheets should also be incorporated into the report to provide the site distance documentation. Indicate if there are any street trees, landscaping req e ents, or any other objects existing or proposed to be within the sight distance triangle. State if the sight distance requirements are met or not and provide any traffic safety mitigation measures. Design Criteria (FWRC 18.55) 1. Block perimeters shall be no longer than 1,320 feet for non -motorized trips, and 2,640 feet for streets (F'WRC 18.55.010 ' and FWCP Policy TP21). Therefore, an east/west connection along the north side of the property and a north/south street connection along the west side (roadway cross sectionI) would be required. However, given that this is a rural development (RS 35,0) with topography constraints, it does not appear that the connections would be appropriate and feasible. Therefore, the applicant may request a modification toeliminate this requirement. 2. All lots shall be accessed by a public street right-of-way (FWRC 18.55.020). The applicant may create a flag lot or use the private driveway standard (Dwg. 3-2CC or 3-2DD) to meet this requirement. In certain cases, lots may be accessed by an ingress/egress and utilities easement or alley subject to the requirements established in the City of Federal Way Public Works Development Standards.

Please find our application, seven site plans, and an area detail map enclosed with this letter/project narrative. The proposal is to create a short plat in the south end of Federal Way along Highway 99. The site consists of parcel 292104-9044, totaling approximately 14.95 acres. The site address is: 36606 Pacific Hwy S, Federal Way. The subject property is zoned RS-35.0 per the Federal Way Revised Code. Property Information: The site slopes gently downward from the northern edge to the southern edge of the property, with a total of approximately 40' of relief across the site. The property contains a large single-family home, a pond and several accessory structures. The site is largely grass, though a significant wetland is located within and adjacent to the southern edge of the property. Surrounding uses are as follows: North: Horse Stables • South: Large Lot Single -Family Residential West: School/Large Lot Single -Family Residential • East: Undeveloped Roads and Access: Access to the proposed new lots is proposed to be provided via a private access easement off of 81h Ave S. The proposed access easement will follow the alignment of the existing driveway. It is anticipated that the existing home will continue to access Pacific Hwy S. The exact level of improvements required by the City for a private access easement serving large lots is not clearly defined in code and will be discussed at the pre - application meeting.

The exactly level of improvements required is not entirely clear. The City code calls for 6' of sidewalk in addition to a 4' landscaping strip, while simultaneously stating that the road should be designed to Cross Section T (attached), which is slightly different. This discrepancy will also be addressed during the pre -application process. The proposed project should not require frontage improvements along Pacific Highway South (SR-99). Utilities: Water service is located within S 373`d St, S 3591h St, and 8th Ave S (approximately 800' south of the property. Extending water from any of these locations would likely be cost prohibitive due to this distance. Extension via 8th Ave S is also encumbered by the presence wetlands and streams near the site. The most likely solution is an upgrade or expansion of the existing on -site exempt well to supply water to the proposed lots. This would require upgrading the existing well to a Group B Water System, which will require Seattle -King County Health Department approval. Sewer service is not presently available near the site. It is likely that any new lots would require the design and approval of individual septic systems through the Seattle -King County Health Department. Critical Areas: A wetland and stream (Hylebos Creek) are located on -site. Per the City of Federal Ways GIS data, the wetland was previously designated as a Category I wetland, requiring a 200' buffer. The City's Critical Areas Ordinance was recently updated, which changed the buffer requirements for Category I wetlands. Depending on the quality of habitat present on -site, the buffer width can vary from 75' to 225' wide. Based on our experience, we estimate that the required buffer width will be 190' or 225' in width. Both buffers are shown on the attached GIS exhibits for reference. The on -site stream is part of the West Hylebos Creek system. According to the City's GIS data, this watercourse has been designated as Type F under the new Critical Areas Ordinance, denoting that it supports or has the ability to support fish. Type F streams require a 100' buffer, but due to the relative locations of the stream and wetland, the required stream buffer is entirely enveloped by the wetland buffer. According to the City's GIS data, the pond located near the western edge of the site is shown as a stormwater detention pond; however, King County GIS data shows it to be a wetland. Since the pond is not delineated on the City's Critical Areas maps, it will likely be treated as a man-made feature and not a critical area. Evidence of its use as a stormwater facility may be necessary in the future. This can usually be provided in the form of as- builts or construction drawings, which can usually be found in the City's files. Site Plan: The attached site plan depicts a total of 4 lots, retaining the existing home, mother-in-law quarters and well site on an 8.3-acre lot. The remaining 3 lots vary in size; however, they all contain approximately 1-acre of upland area unencumbered by critical areas and their buffers. This lot size is important as the Seattle -King County Health Department usually requires a t1-acre minimum lot size for on -site individual septic systems. r (@7u A st 27, 2015 Page 3 We look forward to meeting with you to discuss the project in more detail.

Such regulations focus on the avoidance of adverse impacts to wetlands and the mitigation of such impacts that cannot be avoided. In addition, City of Federal Way has established criteria to categorize wetlands for purposes of regulation and requires a buffer along wetland and drainage corridor areas. As presently defined for the site the proposed action is to add an addition to the house. The addition will be added to the northeast, away from the critical areas. The on -site wetland will be protected by standard buffer and no encroachment is planned as part of development.

Mark Heckert BCES 4 18024 — Brambila House WetRept INTRODUCTION This report details the activities and onsite evaluations undertaken to complete a wetland and drainage corridor evaluation as an element of the planning and site development of the Brambila Residence Site. The Brambila Residence Project Site is an approx. 15- acre project area comprised of one parcel (#2921049044), located at 36606 Pacific Hwy. South, City of Federal Way, Washington. The evaluation and delineation of onsite and adjacent wetlands and drainage corridors is a vital element in the planning and selection of a site development action. The goal of this approach is to assure that planned site development does not result in adverse environmental impacts to regulated wetlands, streams, and their associated protective buffer areas. Wetlands are generally defined as "those areas that are inundated or saturated by surface water 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." (City of Federal Way Title 15). The purpose of this document is to present the results of an onsite assessment and evaluation of wetland areas within the Brambila Residence Project Site following the methods and procedures outlined in the Corps of Engineers (CoE) Wetland Delineation Manual - 2010 Western Mountains, Valleys, and Coast (WMVC) Regional Supplement and City of Federal Way Code 15 (Critical Areas), and categorized using the Revised Washington State Wetland Rating System (WSWRS). Drainage corridors were also assessed in accordance with the criteria established by City of Federal Way and the State of Washington Department of Natural Resources (WDNR) Forest Practice Rules (WAC 222-16-030). This study was designed to accommodate site planning and potential regulatory actions and is suitable for submittal to federal, state, and local authorities for wetland and stream boundary verification and permitting actions. The project area is generally rectangular, approximately 15 acres in size. The site contains a house, workshop, lake, and ornamental gardens. The northern portion of the site has been cleared of most woody vegetation, and is maintained as lawn. A created lake and stream occur in the southwest. 1 18024 — Brambila House WetRept -kxr-lweril M I&TA =1 I W-11 0 19 The National Wetland Inventory (NWI) mapping completed by the U.S. Fish and Wildlife Service was reviewed as a part of this assessment (fig. 2). This mapping resource identified a PFOC, PEM1A, PSSC, PUBH wetland through the south and western part of the parcel, and continuing significantly offsite to the northwest and south. CITY OF FEDERAL WAY WETLAND INVENTORY The City of Federal Way Wetland Inventory Mapping was reviewed as a part of this assessment (fig. 3). This mapping resource identified a Cat. 1 Wetland through the south and southwest corner of the site, and a major stream (West Hylebos Creek) in the southwest corner of the site, and a major stream (Hylebos Creek) in the southeast corner of the site. Wetland continues significantly offsite. G1111111 1 J 1111111 WDFW Priority Habitats and Species (PHS) data was reviewed as a part of this assessment (attached). This mapping resource identified "documented" anadromous fish habitat and resident migratory utilization in the two streams and a wetland complex in which the site is included. PFSTRRIZ�� Soil Resource Report by NRCS was reviewed as a part of this assessment (fig. 5). This mapping identified the following soils throughout the project site: Bh - Bellingham silt loam, No - Norma sandy loam, Tu - Tukwila muck. These soils are listed as "hydric". ONSITE ANALYSIS CRITERIA FOR WETLAND AND STREAM IDENTIFICATION Wetlands are transitional areas between aquatic and upland habitats. In general terms, wetlands are lands where the extent and duration of saturation with water is the primary factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface (Cowardin et al., 1979). Wetlands are generally defined within land use regulations as "areas that are inundated or saturated by surface or groundwater 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" (CoE Manual). 2 18024 — Brambila House WetRept Wetlands exhibit three (3) essential characteristics, all of which must be present for an area to meet the established criteria within the Wash. Manual and the CoE Manual. These essential characteristics are: 1. Hydrophytic Vegetation: A predominance of plants that are typically adapted for life in saturated soils. 2. Hydric Soil: A soil that is saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper horizons. 3. Wetland Hydrology: Permanent or periodic inundation, or soil saturation to the surface, at least seasonally. RVUNOIZ•r BCES Consulting completed a specific onsite evaluation of the project area on May 15, 2018. The objective of this evaluation was to define and delineate potential wetland and drainage corridor areas which may be present within and adjacent to the project area as defined by the three -parameter criteria test noted within the Wash. Manual and CoE Manual, and the water -typing criteria noted within the WDNR Forest Practice Rules (WAC 222-16-031). Boundaries between wetland and non -wetland areas were established by examining the transitional gradient between wetland and non -wetland characteristics criteria throughout the site. Delineation was performed using the routine methodology for areas greater -than than five acres as detailed in the CoE Manual. As defined by existing site conditions and aerial photos, the project site has experienced extensive use and development. The site was a large residential parcel, with the house in the center of the site, a workshop east, gazebo, and sheds east of the house. A constructed pond is situated in the southwestern boundary. A stream transects the site along the south boundary, and another in the southwest corner. The stream in the southwest corner appears to have been restored by rerouting the streambed and adding gravels, and enhanced with vegetative plantings. The majority of the project site was comprised of Norma sandy loam, a hydric soil. The soils through the southern and western majority of the site are dark gray to black silt loam and peat, with concretions and organic streaking. This area appears to remain saturated to the surface well into the growing season. The surface soil layer within the Wetlands A depression was generally silt loam. Soils in Wetland A meet the hydric soil criteria. 3 18024 — Brambila House WetRept MKM= Hydrology within the project area appeared to be the result of hydro support by the streams, and seasonal storm water runoff from onsite and adjacent properties; long and short-term seasonal ponding and soil characteristics. The constructed pond is supported by a spring at the north end of the feature. Stormwater surface runoff through the overall project area was directed by topography to the south into the wetland area. anu�� The primary plant community is the mixed forested portion of the property along the southern boundary dominated by trees: Fraxinus latifolia (Oregon ash), Anus rubra (Red alder), and a few Salix lasiandra (Pacific willow). This plant community was identified as hydrophytic in character (i.e. typical of wetlands) in the areas identified as wetlands in the west portion of the site. The plant community outside the wetland areas was identified as non-hydrophytic in character (i.e. not typical of wetlands). Wetland determination was based on sample plots which contained hydrophytic vegetation, hydric soils, and wetland hydrology in accordance with the CoE Manual and the Wash. Manual. Based on these methods one wetland was identified within the project area. Two areas were identified onsite to exhibit characteristics typical of a stream. One area was identified onsite to exhibit characteristics typical of a pond. WETLAND A SIZE CITY OF WA WETLA (sqft.)

Wetland size onsite — west & south boundary not defined, continues offsite Wetland A: This wetland is located throughout the south and western portions of the site, and continues substantially offsite to the north and south. Hydrology for this wetland was provided by primarily by overbank flooding from the streams, seasonal precipitation, and spring to the pond. Wetland A contains a created pond. This pond appears to have been created in wetland. 4 18024 — Brambila House WetRept The buffer for Wetland A has been cleared and landscaped to the wetland edge as part of previous development. A fence and paved driveway transect the buffer adjacent to the created pond. Since this wetland scored 25 Points by WSWRS, this wetland appeared to meet the criteria for designation as a City of Federal Way Category 1 Wetland. General buffer for a City of Federal Way Category 1 Wetland is 200 ft. Major Stream A: Major stream A is a stream which originates north of the project site and flows onsite in the southeast corner of the site. This stream provides habitat for both anadromous and resident fish species and has perennial flow. This stream meets the criteria for designation as a Major stream. Major streams require a 100 ft. buffer from the stream edge [Ordinary High -Water Mark]. Major Stream B: Major stream B is a stream which originates northwest of the project site and flows onsite through a culvert under Hwy. 99. This stream provides habitat for both anadromous and resident fish species and has perennial flow. This stream meets the criteria for designation as a Major stream. Major streams require a 100 ft. buffer from the stream edge [Ordinary High -Water Mark]. Offsite Wetlands: Wetland A continues substantially offsite to the north and south. WETLAND FUNCTION AND VALUE ASSESSMENT Wetlands are known to perform significant roles in the ecosystem, some of which are of immediate value to society. These roles vary greatly with the size, type, hydrology, vegetation, and location of wetland areas. Although the ecological functions performed by these wetlands are complex, interrelated, and difficult to assess and quantify, methods have been developed for the U.S. Army Corps of Engineers (FGDC, 2013). The functions provided by wetlands include hydrologic support, shoreline protection, stormwater and floodwater storage, water quality, groundwater recharge, and provision of wildlife habitat. CATEGORIZATION BASED ON FUNCTIONS The functions that a wetland performs are characterized by answering a series of questions that note the presence, or absence, of certain indicators. Indicators are easily observed characteristics that are correlated with quantitative or qualitative observations of a function (Hruby et al. 2000).

Total scores between 20-22 are Category 11; 16-19 are Category III, and less than 19 are Category IV, The wetland areas identified within the overall project area were evaluated following the functional value assessment process noted above. As identified in this assessment Wetland A would be considered to have the overall functional rating of Category 3. 0 Water Quality Functions — 8 points 0 Hydrologic Functions — 8 points 0 Habitat Functions — 9 points & TOTAL score for functions — 25 points The proposed alteration of lands defined by various federal, state, and local authority rules and regulations as "wetlands" raises environmental concerns that are generally addressed in the development review process. These concerns center on the development's potential adverse impacts to the structure, function, value, and size of these "wetland" areas. Such adverse impacts may include a reduction in wildlife habitats, reduced surface water quality, reduced water retention, a reduced ground water recharge 6 18024 — Brambila House WetRept rate, reduced plant species diversity, and the reduction in the function and value of other associated wetland and non -wetland characteristics. Section 404 of the Clean Water Act (33 U.S.C. 1344) prohibits the discharge of dredged or fill material into "Waters of the United States" without a permit from the Corps of Engineers (Corps). The Corps has jurisdiction over freshwater systems waterward from the ordinary high water line of a water body or waterward from the upland boundary of the adjacent wetland. The definition of fill materials includes the replacement of aquatic areas with dry land, grading which changes the surface contour of a wetland, and mechanized land clearing in wetlands. For the purposes of Section 404 permitting the Corps makes the final determination as to whether an area meets the wetland definition and would be subject to regulation under the Corps program. Currently the Corps has two specific types of permits which apply to wetland fill proposals. These two types are a series of specific Nationwide Permits and the Individual Permit. The Nationwide Permit process identifies specific categories of work that can be undertaken following a set of specific conditions applicable to each Nationwide Permit number. The Corps requires an Individual Permit where a proposed activity within an identified jurisdictional wetland area can not be authorized under one of the Nationwide Permits. Within the Individual Permit process the Corps undertakes a much more in-depth review of the proposed project and the proposed impacts. The Corps must evaluate whether the benefits derived from the project outweigh the foreseeable environmental impacts of the project's completion. All projects that proceed forward using either one of the Nationwide Permits or the Individual Permit process must also comply with the provisions of the Endangered Species Act. As defined by a recent U.S. Supreme Court decisions the Corps of Engineers does not typically regulated "isolated" wetlands pursuant to Section 404 of the Clean Water Act. Under this decision "isolated" wetlands do not exhibit a continuous surface water connection to other, downstream aquatic system. Proposed action undertaken through either of the Corps of Engineers processes (Nationwide or Individual) are also subject to the provisions of the Washington State Department of Ecology Section 401 Water Quality Certification Process. Projects that may be exempt from Corps of Engineers Section 404 jurisdiction may still require review by the Washington State Department of Ecology to ensure consistency with State water quality protection provisions. 7 18024 — Brambila House WetRept 15.10.270 Structures, improvements, and clearing and grading within regulated wetland buffers. (1) Generally. Except as allowed in this section, no clearing and grading may take place and no structure or improvement may be located within a regulated wetland buffer. (2) Wetland buffer averaging. Wetland buffers may be averaged only when the wetland or the buffer which is proposed to be reduced contains habitat types which have been so permanently impacted that reduced buffers do not pose a detriment to the existing or expected habitat functions. Through Process III per Chapter 19.65 FWRC, the applicant must demonstrate to the satisfaction of the shoreline administrator that the proposed buffer averaging will meet all of the following criteria: (a) Reduced buffers will not affect the water quality entering a wetland or stream; (b) Reduced buffers will not adversely affect the existing quality of wildlife habitat within the wetland or the buffer; (c) Reduced buffers will not result in unstable earth conditions nor create erosion hazards; and (d) Reduced buffers will not be detrimental to any other public or private properties, including the loss of open space. At no point shall the buffer width be reduced to less than 50 percent of the required standard buffer width, unless the buffer, in existing conditions, has already been permanently eliminated by previous, legally permitted actions. The total area contained within the buffer after averaging shall be equal to the area required for standard buffer dimensions. (3) Essential public facilities, public utilities, and other public improvements. The shoreline administrator may permit the placement of an essential public facility, public utility, or other public improvements in a regulated wetland buffer if he or she determines that the line or improvement must traverse the buffer because no feasible or alternative location exists based on an analysis of technology and system efficiency. The specific location and extent of the intrusion into the buffer must constitute the minimum necessary encroachment to meet the requirements of the public facility or utility. s 18024 — Brambila House WetRept As presently defined for the site the proposed action is to add an addition to the northeast side of the existing house.

Your wetland unit seems to be difficult to classify and probably contains severaldifferent H8K8classes. 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 the wetland unit being scored. 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 HGM 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. Ifyou are still unable to determine which of the above criteria apply to your wetland, or if you have more than HGM classes within a wetland boundary, classify the wetland as Depressional for the rating.

Bogs Does the wetland (or any part of the unit) meet both the criteria for soils and vegetation In bogs? Use the key below. If you answer YES you will still need to rate the wetland based on its functions. SC 3.1. Does an area within the wetland unit have organic soil horizons, either peats or mucks, that compose 16 in or more of the first 32 in of the soil profile? Yes - Go to SC 3.3, El_; NO - GO to SC 3.2' SC 3.2, Does an area within the wetland unit have organic soils, either peats or mucks, that are less than 16 in deep over bedrock, or an impermeable hardpan such as clay or volcanic ash, or that are floating on top Of a lake or pond? es - Go to SC 3.3 No = Is not a bog' SC 3.3. Does an area with peats or mucks have more than 70% cover of mosses at ground level, AND at least a 30% cover of plant species listed in Table 4? Yes = Is a Category I bog IE3 No - Go to SC 3.4' NOTE: If you are uncertain about the extent of mosses in the understory, you may substitute that criterion by measuring the pH of the water that seeps into a hole dug at least 16 in deep. If the pH is less than 5.0 and the plant species in Table 4 are present, the wetland is a bog. SC 3.4. Is an area with peats or mucks forested (> 30% cover) with Sitka spruce, subalpine fir, western red cedar, western hemlock, lodgepole pine, quaking aspen, Engelmann spruce, or western white pine, AND any of the species (or combination of species) listed in Table 4 provide more than 30% of the cover under the canopy?
