All or some of the open space requirement may be satisfied by a fee -in -lieu payment at the discretion of the Parks Director. If open space is provided onsite, it shall be provided in its own tract. As with other tracts, an open space tract cannot count towards the minimum lot area of a lot/lots. • Public Works Development Services Division 1. The site is divided (topographically), by a north -south oriented ridge or high point. This ridge splits the site into 2 separate, distinct threshold discharge areas. The westerly discharge area is in a Conservation (Level 2) flow control area, while the easterly discharge area is in a Flood Problem (Level 3) flow control area. See additional comments below for additional details as to what this means in regard to storm drainage for the project. 2. The applicant is advised that the City expects to adopt a new stornwater manual in 2016. While it's not known at this time when adoption of a new manual is expected, we feel it's important to provide this information so that the owner/applicant is aware of this upcoming change. If the applicant submits a complete Preliminary Short Plat application after City adoption of a new manual, then the project will be subject to the stormwater regulations and requirements of that manual. If the applicant submits a complete Preliminary Short Plat application before adoption of the new manual, then the project is subject to the stormwater requirements of the current (2009) King County Surface Water Design Manual (KCSWDM), and City addendum to the manual. Public Works Traffic Division l . A Transportation Concurrency permit is required per FWRC Chapter 19.90. 2. Street frontage improvements and right-of-way dedication are required along the property frontage on SW 318"' St and 6"' P1 SW per FWRC 19.135.040. 3.

DEPARTMENT COMMENTS Outlined below are the comments made by the representatives of each department present at the preapplication conference. Each section should be read thoroughly. If you have questions, please contact the representative listed for that section. PLANNING DIVISION (Leila Willoughby -Oakes, 253-835-2644, Leila.Willoughby-Oakesna cityoffederalway.com) 1. Existing Site Conditions — The parcel (un-platted lot) is undeveloped, vegetated and contains several tree stands. A developed lot (single family home) with accessory buildings exists to the north and Fishers Pond (city -owned) to the east contains a Category I Wetland (bog). Properties zoned RS 7.2 exist to the west with SW 318°i Street terminating at the subject property's western property line. The 15-10583; -PC Doc ID 71478 December 17. 2015 Mr. Ideker Page 3 property contours are such that the middle of the site is flat and the sides slope downward both east and west. There are no sidewalks or street improvements along the 61h PI SW frontage. Short Plat Process — Pursuant to FWRC 18.30.010, short plat applications are administratively processed through the Department of Community Development. The administrative review process requires that the Director of Community Development issue a decision on the short subdivision request, confirming conformance with FWRC 18.30.1 10(2). After the permit center accepts an application, planning division staff will conduct a completeness review, issuing a letter of completeness or incompleteness requesting additional information within 28 days of receipt. Public notice of the complete short plat proposal is required per FWRC 18.30.080, and a 15-day public comment period is provided. However, no public hearing will be required unless an appeal is filed. A master land use application and short plat handout with submittal checklist are enclosed; relevant code sections are available at the city's website at www.cityoffederalway.com under Title 18- `Subdivision.' Short plats do not require a public mailing to adjoining landowners. 3. Critical Areas — According to city critical area mapping, the subject property is located in a critical aquifer recharge area — the 1- and 5-year wellhead protection zone. The site is a dual rated critical aquifer recharge area. A hazardous materials inventory statement must be submitted with the formal short plat application inventory. Per Project File Number (PFN) 15-105199-AD (administrative decision request), on October 16, 2015, the Planning Division granted a wetland buffer reduction 072104-9093. The buffer related to the Category 1 Wetland 50 feet southwest of the subject property was determined to be permanently altered, due to a right-of-way, 6`' PI SW— dissecting. Therefore, no onsite buffer mitigation will be required. A previous proposal included bio-swales along a private road as wetland buffer mitigation. Fishers Pond contains a Palustrine Aquatic Bed/Forested Wetland (bog), and accordingly, no contaminated or untreated stormwater should leave the site. Please see Kevin Peterson's, Development Services, comments for more stormwater drainage information. 4. Tacoma Smelter Plulne — The Department of Ecology's Facility/Site Atlas indicates the site is located within a soil safety program service area impacted by the Tacoma Smelter Plume. The site has sat undeveloped. The property contains an arsenic concentration of 40.0 ppm-100.0 ppm (arsenic concentrations 0-6" 90`h percentile). The city requests the applicant provide soil tests to the city during construction permits if necessary to obtain written approval of the site's clean-up from the Department of Ecology through their voluntary program. Options for clean-up includes disposing of contaminated topsoil on the site and sending them to a landfill or when arsenic and lead levels are fairly low, applicants may rnix soils with cleaner soils to dilute the contarnination (information enclosed). For.further information contact Eva Barber, Technical Assistance Coordinator at the Department of Ecology, Toxics Cleanup Program at (360) 407-7094 or Eva. Barbe►{aiecy.wa.gov. 5. State Environtnental Policy Act (SEPA) —Short plats are exempt from the requirements of SEPA review per Washington Administrative Code (WAC) 197-11-800, Categorical Exemptions. 6. General Zoning a. `Detached Dwelling Units' are a permitted use in the RS9.6 zoning district. b. Maximum height of structures-30 feet above average building elevation. 15-10.833-PC Doc ID 71478 December 17. 2015 Mr. ldeker Page 4 c. Maximum roof eave overhang within the required yard is 18 inches (1.5 feet). d. Lot Size —The zoning for the subject site is RS-9.6. The minimum lot size in this zone is 9,600 square feet. As depicted, the proposed Lots 1-4 meet the minimum lot size requirements. The proposed access easements serving Lots 1-4, and required open space tract will not be counted towards minimum lot sizes. e. Setbacks— Future residences must conform to the following building setback requirements of FWRC 19.200.010, "Detached Dwelling Units": front yard —twenty feet; side yard —five feet; and rear yard —five feet. All structure setbacks are measured from the access easement on this project. Rear -yards shown on plans are 10 feet whereas 5 feet is permitted. f. Driveway Standards (FWRC 19.130.240) — Residential driveways serving a two -car garage shall not exceed 20 feet in width. A driveway serving a three -car garage may exceed 20 feet in width if the subject property is at least 60 feet in width and the garage is located not more than 40 feet from the front property line. Driveways may not be closer than five feet from any side property line. Please refer to Traffic Division comments for public street standards. g. Parking— Two spaces per dwelling unit. h. Lot Coverage — Maximum permitted lot coverage is 60 percent of the total lot area. The following describes calculating lot coverage: "19.110.020 Calculating lot coverage. (1) General. Except as specified in subsection (2) of this section, the area of all structures, pavement and any other impervious surface on the subject property will be calculated as a percentage of total lot area, exclusive of the area of any recorded access easements, in detenmining compliance with maximum lot coverage required in this title. If the subject property contains more than one use, the maximum lot coverage requirements for the predominant use will apply to the entire development. "(2) Exceptions. The following shall be excepted from the provisions of this section: (a) A wood deck will not be considered as an impervious surface for maximum lot coverage proposed if the deck is constructed with gaps between the boards and if there is a pervious surface below the deck. (b) A vehicular access easement, private tract, or that portion of a private driveway located within the "flag pole" or "access panhandle" part of the lot will not be used or considered in determining compliance with the maximum lot coverage requirement of this title. (c) One-half of the area covered with grass grid pavers will be considered as impervious surface in determining compliance with the maximum lot coverage requirement of this title." 7. Subdivision Design Criteria — Short plats are subject to the subdivision design criteria of FWRC 18.55. • Land Division Design (Block Perimeter) — Please see Traffic Division comments on compliance issues (Contact Sarady Long, Senior Traffic Engineer). 15-10 833 -PC Doc ID 71478 December 17. 2015 Mr. Ideker Page 5 Open Space —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). 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 Category % of Gross Land Area Usable 10% minimum Conservation No maximum or minimum Buffer 29/o maximum Constrained 2% maximum Approximately 3,303 sq. ft. of open space is depicted on the conceptual plans submitted as Tract `C'; no development or accessory structure encroachments may occur in this area. Therefore, a fee in -lieu of open space payment of approximately 10% (based on this proposal) of the assessed land value shall be paid in addition to physical open space designated on site. Per FWRC 18.55.060.6, "Open space shall be owned in common undivided interest by all property owners within the land division as members...." stated as a plat restriction during recording. As with other tracts, an open space tract cannot count towards the minimum lot area of Lots 1-4. Meeting Follow -Up — Mr. Knowles asked if the proposed stormwater facilities (round -about) may be counted towards open space requirements. Open space may not be counted towards the residential open space requirements of FWRC 18.55.060. If open space on site cannot be provided, the remaining may be fulfilled via the fee -in -lieu of open space process. 9. Homeowners (HOA) —The applicant asked if an HOA would be required. A required HOA would be determined during the preliminary short plat review. All areas owned in common (stonnwater facilities/open space tracts) shall be in a separate tract and contain covenants/plat notes stating areas shall be equally owned and maintained by all owners in the subdivision. Follow -zip: An HOA established for the maintenance of shared facilities will be determined at the time of submission. Minimum requirements include covenants to this effect on the recorded short plat document. 10. Clearing and Grading — 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, if clearing and grading work is proposed. 11. Tree Density 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. In the case of Ii-105837 -PC Duc ID 71478 December 17, 2015 Mr. Ideker Page 6 the 1.51-acre site, approximately 38 tree units are required (25 x 1.51 acres = 37.75 tree units; fractions rounded up to the nearest whole number). Tree unit credits are found in Table 2 of FWRC 19.120.130- 2. Formal applications (preliminary short plat drawing) must indicate which trees will be removed, areas of non -disturbance, and tree protection measures for existing trees. A tree unit is a value assigned to existing trees retained on the property or replacement trees. The larger the tree, the 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 clearly show where the tree units are to be located. Per FWRC 19.120.130.3, the total number of tree units required to be provided by a regulated activity shall be calculated by multiplying gross site acreage, minus any proposed public or private streets and regulated critical areas (excluding buffers). 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. 12. School Impact Fees — School impact fees (currently $4,687.00 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. 13. Approval Duration — Short plat preliminary 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. 14. Fees — Development fees change annually. Contact the Permit Center at 253-835-2607, or periiiiteenter tr cityoffederal►vay.com. Please be aware that additional utility fees, school impact fees, fee -in -lieu of open space, concurrency, and engineering plan review fees may apply. Please note adoption of a new schedule is pending. 15. Recorcling—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. Please ensure all taxes/property liens are paid on the subject property prior to recording, to satisfy the Treasury Office. In addition, all other required improvements must be substantially completed as determined by the departments of Community Development and Public Works. PUBLIC WORKS DEVELOPMENT SERVICES DIVISION (Kevin Peterson, 253-835-2734, kevi n.peterson@cityoffederalway.com) Land Use Issues — Stormwater 1 _ Surface water runoff control and water quality treatment will be required per the 2009 King County Surface Water Design Manual (KCSWDM) and the City of Federal Way Addendum to the 2009 KCSWDM. This project meets the requirements for a Full Drainage Review. At the time of preliminary short plat submittal, a preliminary Technical Information Report (TIR), addressing the relevance of the project to the eight core and five special requirements of the KCSWDM will be required. A Level 1 downstream analysis shall also be provided in the preliminary TIR. The City has 1"= 100', five-foot contour planimetric maps that may be used for basin analysis. IS-10583i-PC Doc ID 71478 December 17. 2015 Mr. Ideker Page 7 2. As noted above, under the Major Issues section, the project site is separated into 2 distinct threshold discharge areas, with separate levels of flow control for each discharge area. The western portion of the site lies within a Conservation (Level 2) flow control area, while the eastern portion lies within a Flood Protection (Level 3) flow control area. Because the threshold discharge areas do not meet within '/4-mile from their points of discharge from the site (refer to the definition of Threshold discharge area in the KCSWDM), there must be 2 separate flow control facilities provided for each threshold discharge area. The applicant must design the flow control facilities to meet the performance criteria identified for each discharge area. In addition to flow control facilities, Best Management Practices (BMP's) are required as outlined in the KCSWDM. 3. The project also lies within an Enhanced Basic Water Quality Area (each threshold discharge area is in the Enhanced Basic Water Quality Area). Water Quality Treatment shall be designed to meet the treatment criteria of the Enhanced Basic Water Quality Menu. 4. The preliminary design drawings indicate the use of Best Management Practices (BMP's) (or Low Impact Design — LID - options) as a means of eliminating (or reducing the size of) detention facilities. While this is allowed and required under the KCSWDM, the use of LID will have to strictly adhere to all of the design criteria (including soils testing) of the KCSWDM. 5. If infiltration is proposed, soil logs prepared by a licensed geotechnical engineer must be provided to verify infiltration suitability. All soils logs and infiltration test methodology shall be per the criteria identified in the KCSWDM. 6. Detention and water quality facilities for short plats must be above ground (i.e. open pond), and shall be within a separate tract. 7. Show the proposed location and dimensions of the detention and water quality facilities on the preliminary plans. 8. If more than one acre will be disturbed during construction, a National Pollutant Discharge Elimination System (NPDES) construction storm water permit may be required. Information regarding this permit can be obtained from the Washington State Department of Ecology at http.//wNvw.ecy.wa gov/programs/wg/storm-vvate-/construction/index.html or by calling 360-407- 6048. Right -of -Way Improvements 1. See the Traffic Division comments from Sarady Long, Sr. Transportation Planning Engineer, 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 title prior to recording. 3. All stormwater treatment and detention requirements outlined above apply to any improvements within the public right-of-way. I5-10593i-PC Doc ID 71478 December 17. 2015 Mr. ideker Page 8 EN Permit Issues I . Engineered plans are required for clearing, grading, road construction, and utility work. Plans must be reviewed and approved by the City. Initial engineering review fees are $569.50 for short plat review, and $68.50 per hour for additional review time. A final TIR shall be prepared for the project and submitted with the engineering plans. Both the TIR and the plans will require the signature/seal of a professional engineer registered/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 on the building lots. Details and fees may be obtained from the Building Department. 3. The Federal Way Public Works Development Standards Manual (including standard detail drawings, standard notes, and engineering checklists) is available on the City's website at llittp://www.cifyoffederalway.com/iiidex.aspx?nid=171 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 with 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 detention and water quality facilities) and street systems during the two-year maintenance period. During 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 and drainage facilities, including short plats, remain the responsibility of the individual property 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, just 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.

Please note that supplemental transportation analysis and concurrency mitigation may be required if the proposed project creates an impact not anticipated in tile, six -year Transportation Improvement Plan (TIP). 2. Based on the submitted materials for a four -lot short plat, the Institute of Transportation Engineers (ITE) Trip Genercrfio►t - Wh Edition, land use code 210 (Single Family), the proposed project is estimated to generate approximately 6 new weekday PM peak hour trips. 3. The estimated 2015 fee for the concurrency permit application is S&LZ 00 (1-10 Trips). This fee is an estimate and may change afl:er December 31, 2015. The concurrency application fee must be paid in full at the time the concurrency pennit application is submitted witty land use application. The fee may change based on the new weekday PM peak hour trips as identified in the concurrency trip generation. The applicant has the option of having an independent traffic engineer prepare the concurrency analysis consistent with City procedures; however, the fee remains the same. Transportation Impact Fees (TIF) (FWRC 19.91) Based on the submitted materials for four (4) single family lots, the estimated traffic impact fee is 115,320. The actual fee will be calculated and paid at the time of plat recording. The applicant may defer pars or all of the impact fee payment amount to either building permit issuance; or to later than closing of the sale of the single family home. If this option is selected, covenants prepared by the City to enforce payment of the deferred fees will be recorded at the applicant's expense on each lot at the time of plat recording for residential land divisions.

All lots will be equal to or greater than 9,600 SF. The main project objective is to minimize the creation of impervious surface and maximize the retention of precipitation that falls on the development. Impervious surface minimization is to protect the two downstream stormwater receiving systems: • Fisher's Pond (to the east). r • Category 3 wetland (offsite to the southwest)'' Access will be handled by a private roadway off of 6th PI SW. Roadway will terminate in an emergency vehicle turnaround (currently a cul-de-sac is proposed). The roadway will be primarily composed of porous HMA so as to maximize retention of site runoff; porous surfacing also provides for water quality requirements. Preliminary indications reveal site soils are very conducive to stormwater treatment via filtration and infiltration, Onsite sidewalks will be constructed of pervious concrete. The sidewalk system will link 6th Place to SW 318th St. A planter strip with street trees will be constructed along the onsite roadway. Roof drainage will be handled by extensive rain garden systems in each of the rear yards. The proponents will request that 6th Place public street improvements be waived or deferred to minimize creation of impervious surface in the Fisher Pond Watershed. Tract A is 35' wide for access and utilities as well as future right-of-way dedication. Tract B is to accommodate private access and utilities associated with the portion of the turnaround outside Tract A. Tract C is open space; the proposed open space area is 0.076 acres (5 % of gross area). The proposal is to pay the "in -lieu -of' fee to mitigate for not meeting the 15% open space requirement. LakeHaven Utility District will provide public water and sewer service to the site.

The property is made up of a forested community that is dominated by red alder (Alnus rubra) and Douglas fir (Pseudotsuga menziesii). Beneath the forest canopy is a shrub layer that is dominated by salmonberry (Rubus spectabilis). No structures currently exist on the property. With the exception of the wetland buffer associated with Fisher's Pond, no other critical areas were identified on the property. 2.2 Proposed Actions The applicant proposes to construct a new two-story single family residence on the subject property (Figure 3). The location of the structure is proposed in the western portion of the property. In addition to the single-family residence, two attached garages and associated concrete parking will be constructed. Access to the residence will be from 6'h Place SW and will consist of a 15-foot wide asphalt driveway. Prior to the construction of these features, areas of the property will be cleared of vegetation and minor grading will occur. 2.3 Regulatory Summary Fisher's Pond is located approximately 50 feet southwest of the subject property and is classified as a Palustrine Aquatic Bed/Forested Wetland. Based on the Washington State Department of Ecology's (Ecology) Washington State Wetland Rating System for Western WA — Revised (Hruby 2006), and the City of Federal Way Revised Code (CFRC 19.175), Fisher Pond is a Category I .wetland and shall have a standard buffer width of 200 feet. Although the subject property does not contain any critical areas, Fisher's Pond is located within 200 feet of the subject property (Grette Associates 2012). Typically, only local jurisdictions regulate wetland buffer impacts. Soltys Wetland Buffer 2 October 2013 Mitigation Plan Grette Associates, LLC Figure 2.

As described above in Section 2.3, there are no critical areas within the subject property. However, southwest of the property, across 6'h Place SW, is a Category I wetland (Fisher's Pond) that is within 200 feet of the property. A portion of the 200- foot buffer for this wetland extends onto the subject property (Figure 3). Within the subject property there is approximately 17,976 square feet of wetland buffer area. No impacts to critical areas are proposed for this project. The affected critical area buffer is summarized below in Table 1. Table 1. Proposed Critical Area Impact Summary by Type. Impact Type Impact Area (sf) Duration Wetland Buffer 1,741 sf Permanent Total 1,741 sf 3.1 Wetland Impacts No wetland impacts will occur during the proposed project. 3.2 Wetland Buffer Impacts The proposed project will construct a new 15-foot wide asphalt driveway, extending approximately 226 linear feet from 6`h Place SW to the proposed location of the new single-family residence (Figure 3). The total length of the driveway that is proposed within the wetland buffer area is approximately 116 feet and will permanently remove approximately 1,741 square feet of wetland buffer area. In addition, during the construction of the proposed driveway there will likely be temporary wetland buffer impacts adjacent to the driveway footprint. These impacts will be associated with the grading and clearing of the driveway area and will occur over a 1 to 3 week period. 3.3 Affected Functions and Values The wetland buffer area that is within the subject property is forested with a dense shrub layer beneath. However, the existing wetland buffer west of 6`h Place SW is likely providing little wetland buffer function due to the disconnection from the wetland caused by the paved road. The presence of a Place SW provides a hydrological barrier for surface water that would otherwise flow into the wetland. Currently, the surface water that sheet flows toward the road from the wetland buffer is likely intercepted by the vegetated area adjacent to the paved edge of the road and conveyed to a stormwater catch basin. Although wetland buffer functions are likely limited west of 6`h Place SW, the buffer area does provides some wildlife habitat. The dense vegetation within the property likely provides large and small mammal foraging and cover, passerine, waterfowl, and raptor foraging and nesting, and amphibian foraging and refuge. Social values include aesthetic and ecological characteristics. Soltys Wetland Buffer 5 October 2013 Mitigation Plan Grette Associates, LLC The construction of the proposed asphalt driveway will result in the removal of vegetation that currently provides refuge for wildlife and will reduce stormwater infiltration due to the impervious surface of the driveway. Impervious surfaces do not allow stormwater to infiltrate, thus the water collected on these types of surfaces tend to create a surge of stormwater runoff during rain events. The stormwater will also likely collect sediments and pollutants from the impervious area as the water is conveyed off of its surface. 4 MITIGATION APPROACH The proposed project was designed and configured to avoid and then minimize impacts to the critical areas within the project area. Unavoidable impacts to the wetland buffer will be mitigated through the construction of vegetated bioswales that will be constructed parallel to the portion of the driveway that is within the wetland buffer (Attachment A, Sheet 1 & 2). These actions will be accompanied by revegetating any additional area that is disturbed during the construction of the driveway within the buffer area. 4.1 Mitigation Sequencing As required by the City of Federal Way, this section describes the efforts made by the project proponent to apply mitigation sequencing to the proposed project. Mitigation sequencing is a set of steps designed to prevent unavoidable impacts to the' environment, and then to rectify those impacts that cannot be avoided. The steps considered during the planning of this project are discussed below. 1. Avoidance The environmental impacts associated with the project are unavoidable. Based on the location of the subject property and adjacent properties, the only feasible road access to the property is off of 61h Place SW (Figure 3) and through the wetland buffer. In order to access the subject property a driveway must be constructed through the wetland buffer to connect 6th Place SW. 2. Reduction Relocating the driveway to avoid environmental impacts is not feasible. Based on the City of Federal Way code, CFRC 19.135.270, the maximum driveway width for a single family residence is 20 feet. The proposed driveway has been reduced to IS feet in width. 3. Restoration Due to the requirements needed to access the property, the restoration of the permanently affected area is not feasible. The construction process will require extending approximately 116 feet of asphalt driveway through the wetland buffer area, which will permanently remove 1,741 square feet of wetland buffer. Areas outside of the permanently lost buffer that are temporarily affected by Soltys Wetland Buffer 6 October 2013 Mitigation Plan Grette Associates, LLC construction of the driveway will be restored to pre -impact conditions as specified below in Section 5.2. 4. Compensation .The project proponent proposes to compensate for the affected functions within the wetland buffer area through the construction of vegetated bioswales and by restoring any portion of the wetland buffer that is disturbed during the construction. The proposed bioswale construction and buffer restoration will occur immediately adjacent to the driveway (Appendix A). 4.2 Goals and Objectives The overall goal of the Mitigation Plan is to compensate for lost of wetland buffer functions resulting from project construction. More specific mitigation goals include: • Providevater quality enhancement; ■ Provide enhanced hydrological wetland buffer function; ■ Restore upland vegetation diversity. Specific Functional objectives of the Plan include: 1. Create two 4 ft. x 70 ft. vegetated bioswales; 2. Restore upland vegetation in all disturbed areas. 5 COMPENSATORY MITIGATION PLAN Compensatory mitigation will occur on the subject property (Appendix A). Actions proposed at the site include constructing two vegetated bioswales and revegetating any additional area that is temporarily disturbed during the construction of the driveway within the buffer area or mitigation area. The proposed compensation for the project was determined based on the existing wetland buffer functions and conversations with the City of Federal Way planning department. Based on the existing health of the vegetation within the buffer area, enhancement of the wetland buffer (i.e. vegetation enhancement) will likely not increase the existing wetland buffer functions. Therefore, the proposed compensation is designed to provide water quality enhancement associated with stormwater runoff from the proposed driveway and adjacent upland area. The impact area, approximately 1,741 square feet, consists of an approximately 15-foot by 116-foot area where an asphalt driveway will be constructed. This area is currently a forested community dominated by red alder and Douglas fir with an understory of shrubs dominated by salmonberry. 5.1 Target Functions 5.1.1 Wetland Buffer Functions The target function proposed for improvement within the buffer area is water quality. Water quality within the buffer will be enhanced by collecting and treating stormwater Soltys Wetland Buffer 7 October 2013 Mitigation Plan Grette Associates, LLC runoff associated with the proposed driveway. Currently, the groundcover within the forested buffer is mostly bare and likely does not filter out large amounts of sediments and pollutants from surface water. Constructing two bioswales within the wetland buffer area (north and south sides of the driveway) will provide the opportunity to filter out sediments and pollutants from stormwater originating from the driveway. The wetland buffer areas adjacent to the proposed driveway and bioswales will also be planted with native shrubs and seeded with a native seed mix to reduce erosion and increase the native species diversity within the buffer. 5.2 Mitigation Design The intent of the compensatory mitigation actions at the subject property is to offset the permanent loss of function of wetland buffer area within the site. Mitigation actions include constructing two vegetated bioswales and restoration of the adjacent wetland buffer area using native plantings. 5.2.1 Grading Plan Initially, the extent of the proposed grading will be clearly marked, and silt fencing will be installed along the outer grading extents. All vegetation within the areas proposed for excavation and grading will be mechanically removed. Grading and clearing limits within the wetland buffer area will be limited to 10 feet on either side of the paved driveway edge. During excavation and grading, Best Management Practices (BMPs) will be employed to minimize erosion of disturbed surface soils and to prevent sediment -laden runoff from leaving the project site. BMPs to be employed during construction may include (but are not limited to) silt fencing and/or straw bales around the perimeter of the clearing and grading areas, mulching area immediately after completion of grading, and installation of plant material as soon as practical after grading. Once the vegetation is removed, grading will be conducted using bull dozers, excavators, dump trucks and other like equipment as needed to complete the work. Prior to the final grade and paving of the driveway, the two bioswale will be excavated and constructed to typical design standards presented in Attachment A, Sheets 1 and 2. Plantings within the bioswales and adjacent areas will be installed once the final grade and paving is achieved. 5.2.2 Planting Plan Planting installation will be performed in accordance with the specifications outlined in this plan. Any alterations to the planting plan due to site conditions will require approval from the project biologist and appropriate regulatory agencies prior to installation. The project proponent is only proposing planting within the designated mitigation area and bioswales (Appendix A, Sheet 3). The intent of vegetating the bioswales and adjacent areas is to create a vegetated area that will likely provide water quality and hydrological functions within the area proposed for impacts. The herbaceous species will be planted in clumps of four and each clump will be spaced on 2-foot centers and will include Dewey's sedge (Carex deweyana), Soltys Wetland Buffer 8 October 2013 Mitigation Plan Grette Associates, LLC northwest territory sedge (Carex utriculata), and Dagger leaf rush (Juncus ensifolius). Shrub species will be planted in clusters among the emergent vegetation on 4- to 6-foot centers and will include Nootka rose (Rosa nutkana), cluster rose (Rosa pisocarpa), Scouler's willow (Salix scouleriana), and Indian plum (Oemleria cerasiformis). The remaining bare areas within the mitigation site, including the bioswales, will be seeded with an approved native seed mix. 5.2.3 Planting Schedule The proposed planting schedule for the mitigation area is presented below in Table 2. The specific quantities of each species will be calculated during final design of the mitigation action. In order to reduce mortality, a late fall planting installation (October — November) schedule is preferred. Plants should not be installed during or immediately before freezing weather. Table 2.

Any alterations to the planting plan due to site conditions will require prior approval from the project biologist and/or City Planner. All plant materials to be used on the site will be native to Western Washington and will consist of nursery grown stock from a reputable, local dealer. Only native species specified in the approved plant schedule are to be used; no hybrids will be allowed. Plant substitutions must be approved by the project biologist if specified species are not commercially available. Plant material provided will be typical of their species or variety; they will exhibit normal, densely -developed branches and vigorous, fibrous root systems. Plants will be sound, healthy, vigorous plants free from defects and all forms of infestation. 5.2.4 Preparation and Installation of Planting Materials The landscape contractor shall verify the location of all elements of the landscape plan prior to installation. The project biologist may adjust the locations of landscape elements during the installation period as necessary. 1 Emergent species shall be planted with four (4) plugs per clump. _ Soltys Wetland Buffer 9 October 2013 Mitigation Plan Grette Associates, LLC Circular plant pits with vertical sides will be excavated for all container stock. The pits should be at least twice the diameter of the root system, and the depth of the pit should accommodate the entire root system. The bottom of each pit will be scarified to a depth of 4 inches, and the pit should be thoroughly wetted prior to plant insertion to prevent capillary stress. The planting hole shall be amended with a mixture of topsoil and organic material if necessary to provide appropriate rooting media. Broken roots should be pruned with a sharp instrument and rootballs should be thoroughly soaked prior to installation. Set plant material upright in the planting pit to proper grade 'and alignment. Water plants thoroughly midway through backfilling and add Agriform tablets. Water pits again upon completion of backfilling. No filling should occur around stems. Do not use frozen or muddy mixtures for backfilling. Form a ring of soil around the edge of each planting pit to retain water, and install a 2-1/2 inch layer of mulch around the base of each container plant. 5.2.5 Compliance Inspection A compliance inspection will consist of evaluating the plantings immediately after construction to confirm the plan was followed and were installed appropriately. The compliance inspection will also evaluate the construction of the two bioswales. A walk- through survey will be conducted to verify that installation conforms to the approved plan. Following the completion of the compliance inspection, a compliance memorandum will be prepared by a qualified biologist to document the construction and verify that all design features have been correctly implemented. Any changes to the planting plan will also be discussed in the compliance memorandum. Photographs will also be taken to document the completion of the mitigation area. The memorandum will be submitted to the appropriate regulatory staff within 60 days following completion of all compensatory mitigation actions. 5.2.6 Photographic Documentation As described above, photographs will be taken during the compliance inspection in order to obtain representative photographs of the mitigation site. Photographs will be taken at each end planted area to document the planting and the construction of the bioswales. 5.3 Performance Standards Performance standards provide a clear means of evaluating the success of a mitigation action. The following performance standards have been developed to reflect the goals and functional objectives detailed in Section 4.2 of this document. The performance standards specifically related to this project and presented below in Table 3. Soltys Wetland Buffer 10 October 2013 Mitigation Plan Grette Associates. LLC Table 3.

The contingency actions will vary depending on whether physical or biological processes are responsible for non-attairunent of performance standards, and the degree of shortfall. If the Project fails one or more performance standards, but the permitting agencies agree the shortfall is minor, then additional plantings, or like action, prior to undertaking more intense corrective actions may be proposed. 6.1 Contingency Actions This contingency plan identifies a planning process for selecting appropriate actions to address failure of specific performance standards. In order to maintain the flexibility needed to respond effectively and appropriately to biological and/or physical conditions, this plan does not present a specific list of actions that will be taken to remedy all specific types of failures at the site. Failure of biological components of the mitigation actions are more difficult to predict and specific responses are impossible to present in detail. However, the following general approach is anticipated: If the vegetation planted in the planted areas fails to meet the performance standards, additional planting of the same or alternate species may occur.
