PLANNING DIVISION (Stacey Welsh, 253-835-2634, stace .welsh�]a ci offederalway.com 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 and confirm conformance with FWRC 18.30.110(2). 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 are enclosed; relevant code sections are available at the city's website at www.cityoffederalway.com. 2. State Environmental Policy Act (SETA) —This short plat application is exempt from the requirements of SEPA review. 3. Fees —As development fees change annually, please contact the Permit Center at 253-835-2607, or permitcenter@cityoffederalway.com, for an updated fee list prior to submitting your application. Additional utility fees, school impact fees, concurrency, and engineering plan review fees apply. 14-103690 Doc I,D 66327 Mr. & Mrs. Batson August 26, 2014 Page 3 4. Lot Size — The zoning for the subject site is RS-15.0. Minimum lot size for each lot is 15,000 square feet. As depicted, proposed lots 1 and 2 meet the minimum lot size requirement. Note that the off -site wetland's on -site buffer will need to be placed within a tract in the short plat (also see note #12, below). This tract area cannot count towards the lot area for the newly created lots. Additionally, property dedicated to the City for right-of-way frontage improvements may not be counted in lot areas either (see Traffic comments). 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. As with other tracts, an open space tract cannot count towards the minimum lot area of either lot (also see note #8, below). 5. Design Criteria — Short plats are subject to the subdivision design criteria of FWRC 18.55.020. 6. Setbacks — Existing and future residences must conform to the following structural setback requirements of FWRC 19.200.010, "Detached Dwelling Units": front yard —twenty feet; side yard — five feet; and rear yard —five feet. As information, for Lot 1 as it is shown on Sheet 2 of the submitted short plat site plan, the front lot line is off of I` Ave S., as that is where the existing driveway is. As a result, S. 358 h Street requires a side street setback of 10 feet for Lot 1. 7. Miscellaneous Single -Family Residential Regulations — 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. 8. 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, unless the applicant chooses to defer the payment via a covenant recorded against each newly created lot. 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 2% maximum Constrained 2% maximum 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..." As with other tracts, an open space tract cannot count towards the minimum lot area of either lot. 14-103690 Doc. LD. 66327 Mr. & Mrs. Batson August 26, 2014 Page 4 9. 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, if clearing and grading work is proposed. 10. Review FWRC 19.120.120 for minimum standards for rockeries and retaining walls. 11. 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 the 0.92-acre site, it appears that approximately 23 tree units are required (25 x .92 = 23). Tree unit credits are in Table 2 of FWRC 19.120.130-2. The formal application must indicate if any trees are to be removed. 12. Critical Areas — A portion of the property is located within the buffer of the West Hylebos wetland. According to city critical area maps it is a Category I wetland which requires a 200-foot buffer. Pursuant to FWRC 19.175.040, land surface modification is not permitted and no structure or improvement may be located within a regulated wetland buffer. A professionally prepared wetland report that identifies the location of the wetland buffer on the project site is required as part of the short plat submittal per FWRC Chapter 19.10.030 and 19.175.010.2. The applicant is responsible for providing the report to the City and for covering the cost of the City's consultant who may review the report. The City recently started a Critical Areas Review Optional Direct Services Program, which provides you with another option for obtaining the services of a qualified consultant (see enclosed handout). The short plat drawing must show the location of the buffer on the site and place it within a tract per FWRC 19.150.070. 13. 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. 14. 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. 15. Recording — The city will record the short plat with the King County Division of Records and Elections subsequent to 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. PUBLIC WORKS DEVELOPMENT SERVICES DIVISION (Ann Dower, 253-835-2732, ann.dower@cityoffederalway.com) Land Use Issues — Stormwater 1. Surface water runoff control and water quality treatment is regulated by the 2009 King County Surface Water Design Manual (KCSWDM)'and the City of Federal Way Addendum to the 2009 14-103690 Doc. 1.D. 66327 Mr. & Mrs. Batson August 26, 2014 Page 5 KCSWDM. This project meets the requirements for Small Project Drainage Review as outlined in the KCSWDM. 2. The project lies within a Conservation Flow Control Area; however, a flow control facility may not be necessary for this project. The project also lies within an Enhanced Basic Water Quality Area. However, since required street improvements are limited, water quality treatment may not be necessary for this project. 3. At the time of preliminary short plat submittal, a small project drainage plan shall be submitted. Flow Control Best Management Practices (BMP's) for the new single-family lot must be shown. If the lot layout and footprint of the proposed house is known, then a design must be provided showing that the new lot can accommodate the runoff from the new impervious surfaces. If the new home information is not available, then a theoretical BMP design must be provided, assuming a minimum of 4,000 square feet of new impervious surface on the new lot. New impervious area created by required frontage improvements must be calculated. If square footage thresholds for water quality or flow control are exceeded, the developer will need to provide detention and/or water quality facilities meeting the Conservation Flow Control and Enhanced Basic Water Quality standards. 4. Provide soil logs prepared by a licensed geotechnical engineer or septic designer to verify infiltration suitability. Also show the location of existing and proposed septic systems. Right -of -Way Improvements 1. See the Traffic Division comments from Senior Traffic Engineer Erik Preston for traffic related items. 2. Dedication of additional right-of-way will be required and shall be conveyed to the city through a statutory warranty deed. The dedicated area must have clear title prior to recording. 3. FWRC 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. Engineering (EN) Permit Issues 1. Engineered plans are required for clearing, grading, road construction, and utility work. Plans must be reviewed and approved by the city. Engineering review fees are $549.50 for the first 8 hours of review, and $68.50 per hour for additional review time. Engineering plans will require the signature/seal of a professional engineer registered/licensed in the State of Washington. 2. The Federal Way Development Standards Manual (including standard detail drawings, standard notes, and engineering checklists) is available on the city's website at www.ci offedera[wa .com, to assist the applicant's engineer in preparing the plans and drainage narrative. 3. 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 14-103690 Doc, LD. 66327 Mr. & Mrs. Batson August 26, 2014 Page 6 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. 4. The developer will be responsible for the maintenance of the street improvements 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 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. 5. 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 noted. 6. Drawings submitted for plan review shall be printed on 24" x 36" or 22" x 34" paper. All final approved drawings shall be drafted/plotted on 24" x 36" or 22" x 34" mylar sheet with permanent black ink. Site plans shall be drawn at a scale of 1" = 20', or larger. Architectural scales are not permitted on engineering plans. 7. Provide cut and fill quantities on the clearing and grading plan. Erosion control measures, per Appendix D, 2009 KCSWDM, must be shown on the engineering plans. 8. The site plan shall show the location of any existing and proposed utilities in the areas affected by construction. PUBLIC WORKS TRAFFIC DIVISION (Erik Preston, PE, 253-835-2744, erik. restonrer)citvoffederalway.com Transportation Concurrency Analysis (FWRC 19.90) 1. Based on the submitted materials for 1 additional single-family home, the Institute of Transportation Engineers (ITE) Trip Generation - 8th Edition, land use code 210 (Single -Family Detached Housing), the proposed project is estimated to generate approximately 1 new weekday PM peak hour trip. Alternatively, the applicant may submit a site specific trip generation study for the proposed development. 2. A concurrency permit is required for this development project. The PW Traffic Division will perform concurrency analysis to determine if adequate roadway capacity exists during the weekday PM peak period to accommodate the proposed development. Please note that supplemental transportation analysis and concurrency mitigation may be required if the proposed project creates an impact not anticipated in the six -year Transportation Improvement Plan (TIP). 3. The estimated fee for the concurrency permit application is $344.50 (1 - 10 Trips). This fee is an estimate and based on the materials submitted for the preapplication meeting. The concurrency application fee must be paid in full at the time the concurrency permit application is submitted with land use application. The fee may change based on the new weekday PM peak hour trips as identified 14-103690 Doe, ID 66327 Mr. & Mrs. Batson August 26, 2014 Page 7 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) Residential Land Divisions —Based on the submitted materials for 1 single family lot, the estimated traffic impact fee is $3,205.30. The actual fee will be calculated and paid at the time of plat recording. The applicant may defer part 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, a covenant 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. Street Frontage Improvements (FWRC 19.135) 1. The applicant/owner would be expected to construct street improvements consistent with the planned roadway cross -sections as shown in Map III-6 of the FWCP and Capital Improvement Program (CIP) shown as Table III-19 (FWRC 19.135.040). Based on the materials submitted, staff conducted a limited analysis to determine the required street improvements. The applicant would be expected to construct improvements on the following streets to the City's planned roadway cross -sections: ■ 1 st Avenue S is a Minor Arterial planned as a Type "O" street, consisting of a 34-foot street with curb and gutter, 6-foot planter strips with street trees and streetlights, and 8- foot sidewalks in a 68-foot right-of-way (ROW). Assuming a symmetrical cross section, 4-foot ROW dedication and half -street improvements are required as measured from the street centerline. S 358th Street is a Local Street planned as a Type "W" street, consisting of a 28-foot street with curb and gutter, 4-foot planter with street trees, 5-foot sidewalks with streetlights in a 52-foot ROW. Assuming a symmetrical cross section, 1-foot ROW dedication and half -street improvements are required as measured from the street centerline. 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. These modification requests have a nominal review fee currently at $105.50. Staff may support a modification request to waive the street frontage improvements for S 358th Street. Access Management (FWRC 19.135) 1. Access management standards are based on roadway safety and capacity requirements. FWRC 19.135.280 provides access standards for streets based on planned roadway cross -sections. Please note that access classifications are per Drawing 3-1A in the Public Works Development Standards. 2. Per FWRC 19.135.280, driveways that serve only residential use may not be located closer than 25 feet to any street intersection. The City may further limit or prohibit access to or from driveway on arterial streets as deemed appropriate for safety. 14-103690 Doc, LD, 66327 Mr. & Mrs. Batson August 26, 2014 Page 8 3. 1st Avenue S is Access Class "4", which permits full access as close as 150 feet to any other street intersection or driveway, whether on or off the subject property. The existing Lot 1 driveway does not meet access management standards and should be modified to access S 358th Street. 4. Lot 2 shall be accessed from -S 358th Street. Design Criteria (FWRC 18.55) All lots shall be accessed by a public street right-of-way (FWRC 18.55.020). 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. Residential lots should not have access onto arterial streets.

After a review of city critical areas maps within the City Of Federal Way I have found that the subject property, parcel # 292104-9042, is potentially l��hln the buffer of the West Hylebos Wetland. According to city critical area maps it is a Category I wetland which requires a 200-foot buffer width. Pursuant to the Federal Way Revised Code (FWRC) 19.175.040 land surface modification is not permitted and no structure or improvement may be located within a regulated wetland buffer. The enclosed map shows the approximate location of the category I wetland and associated buffer which affects this property. Critical areas maps produced by the City designate the general location of critical areas, and do not provide exact demarcation of the wetland and associated buffers. If more precise locational information is required it will be necessary to hire a wetland biologist and prepare a wetland delineation. If you have any further questions, feel free to contact me at 253-835-2622 or by email at alexa.heidrich ci offederalwa .coin Sincerely, X&ok Alexa Heidrich Planning Intern Enc: Wetlands and Associated Buffers, prepared by City of Federal Way GIS, June 17, 2011 cc: Email copy to H.
