Show frontage improvements along the property frontage on 9th Avenue South and South 344th Street. These streets are improved with vertical curb gutter, sidewalks, streetlights, etc., but the improvements do not meet the current street standards. The applicant may submit a written request to the Public Works Director to modify, defer, or waive the required street improvements (FWRC 19.135.070). Unles s the Public Works Director approved or modified the required improvement, the applicant would be expected to construct street improvements consistent with the planned roadway cross-sections as shown in Map III-4 in Chapter III of the Federal Way Comprehensive Plan (FWCP) and Capital Improvement Program (CIP) shown as Table III-10 (FWRC 19.135.040). Becky Chaplin Senior Planner City of Federal Way Community Development Department -9- November 24, 2021 • 9th Avenue South Principal Collector planned as a Type “K ” street, consisting of 44’ street with bike lane, 6’ planter strips with street trees, 8’ sidewalks, and street lights in a 78’ right- of-way (ROW). Assuming a symmetrical cross section, half street improvements are required as measured from the street centerline. It appears the existing 39’ right-of- way would be adequate to accommodate planned improvement. • South 344th Street is a Principal Collector planned as a Type “R” street, consisting of 40’ street with curb and gutter, 4’ planter strips with street trees, 6’ sidewalks, and street lights in a 66’ right-of-way (ROW). Assuming a symmetrical cross section, half street improvements are required as measured from the street centerline Response: See Modification Request to Public Works Development Standards for Frontage Improvements for the formal request to exclude frontage improvements from the project requirements. 2. At a minimum, two curb ramps at 9th Avenue South/ South 344th Street intersection would need to be upgraded to meet ADA. Additional mid-block curb ramps at the easterly property would be expected to be installed as part of this project to meet ADA. Response: Two curb ramps are proposed at the northeast and southeast corners at the intersection of 9th Ave. S. and S. 344th St. The upgrade of the curb ramp at the southeast corner eliminates the need of any mid-block ramps to the east as the sidewalk ends near the eastern boundary of the project site. 3. The driveway width on South 344th Street is wider than the 30’ maximum allowable for a two- lane driveway. Driveway widths may be increased in order to provide adequate width for vehicles that may be reasonably expected to use the driveway, as determined by the Public Works Director. However, a modification must be submitted to the Pub lic Works Director for consideration. Response: See Modification Request to Public Works Development Standards for Driveway Width for the formal request to increase standard driveway width for truck access. 4. Adequate driveway throat length should be provided for safe and efficient traffic circulation. A 40’ throat length is recommended as measured from the face of curb (or edge of traveled way if no curb exists) on the public str eet to the first conflicting drive aisle or parking movements that would conflict with entering and exiting traffic. Response: A 40-foot throat length has been provided. 5. Label dimension of driveway on the plan set. Response: Driveways have been labelled accordingly. 6. Update sheet C1 of 10 to reflect the correct existing r ight-of-way width on 9th Avenue South. The existing half street right-of-way is 39’ as measured from street center and not 30’ as shown on the plan. Becky Chaplin Senior Planner City of Federal Way Community Development Department -10- November 24, 2021 Response: The existing right-of-way has been revised and shown correctly throughout the plan set. 7. The truck circulation site plan depicted trucks traffic will not utilize 9th Avenue South or South 344th Street west of the driveway. Give that the development is consistent with the surrounding businesses, pavement evaluation is not necessary. Response: Acknowledged, no further action required. 8. The truck circulation site plans (turning diagram) should be in the Civil Plans and not in the architectural Plans. Response: The truck circulation site plan has been moved to the Civil Plan set. 9. It appears the turning truck will mount the driveway curb within the internal site drive aisle; consider modifying the driveway to accommodate the turning truck. Response: The access has been modified to accommodate truck turning without mounting the curb. SEPA Checklist: 10. Transportation - 14.a: Update this section to specify truck traffic will utilize the driveway on South 344th Street as the primary access to Pacific Highway South (SR 99). Response: This section has been updated accordingly. 11. Transportation – 14.d: Half-street improvements to 9th Avenue South and S 344th Street are required per code. However, the applicant may submit a modification request to modify or waive these improvements. This section will nee d to be update to reflect the Public Works Director’s decision if a modification request is submitted. Response: See Modification Request to Public Works Development Standards for Frontage Improvements for the formal request to exclude frontage improvements from requirements. PUBLIC WORKS – DEVELOPMENT SERVICES DIVISION Kevin Peterson, 253-835-2734, kevin.peterson@cityoffederalway.com 1. The applicant shall provide additional details for their Solid Waste and Recycling (SWR) facilities, including storm water management, per FWRC Section 19.125.150; Response: SWR facilities to be fully enclosed and sealed within container. Additional details added to Architectural Site Plan and sheet C6 of the civil plan set. 2. According to the geotechnical report, groundwater was noted at 8.5 feet below finish grade (TP #5 – page 7 of the pdf file), and it was concluded that this should be used in design considerations. With the bottom of the infiltration trench designed at 6-feet below existing grade (2.5 feet above the ‘design’ groundwater elevation), and per the requirements of the Becky Chaplin Senior Planner City of Federal Way Community Development Department -11- November 24, 2021 2016 King County Surface Water Design Manual (KCSWDM), Section 5.2.1, a groundwater mounding analysis shall be performed to ensure the infiltration facility will perform as designed; Response: To clarify, groundwater monitoring indicates that the seasonal high-water table is approximately 8.5 feet below the existing grade (elevation 248). The bottom of the infiltration trench (see Sheet C8 for more details) is located approximately 6-feet below the proposed finished grade (elevation 253). The geotechnical report created by Terra Associates, Inc. reiterates the separation being at least 5-feet in section 4.7 Infiltration Feasibility of the before mentioned report. A mounding analysis is currently being completed and will be submitted under a separate cover. 3. A revised Technical Information Report is required that addresses the facility sizing for the detention and water quality facilities, due to the added parking area (not included in original submittal) along 9th Ave S. Response: The revised Technical Information Report has been included as part of this submittal. LAKEHAVEN WATER AND SEWER DISTRICT Brian Asbury, 253-946-5407, BAsbury@lakehaven.org 1. Regarding the city’s completeness review for the subject application/project, the applicant has completed and submitted to Lakehaven an application for Certificates of Availability, and Lakehaven issued these Certificates on May 24, 2021. However, no other application has been submitted to Lakehaven that is necessary to be able to determine the applicant’s specific requirements for connection to Lakehaven’s water and/or sewer systems to serve the subject property. As previously noted, applicant will need to submit an application for either Developer Pre-Design Meeting or Developer Extension Agreement for Lakehaven to formally commence the water (and sewer) plan review process. Lakehaven encourages owners/developers/applicants to apply for Lakehaven processes separately to Lakehaven, and sufficiently early in the pre-design/planning phase to avoid delays in overall project development. Response: A draft Developer Extension Agreement has been submitted to LWSD for review. SOUTH KING FIRE AND RESCUE Sean Nichols, 253-946-7242, sean.nichols@southkingfire.org 1. The hydrant nearest the FDC, needs to be moved across the drive aisle so Fire doesn’t block the road with hose if they needed to connect to the yard FDC. Response: The proposed fire hydrant has been moved to within the planter across the drive aisle. Becky Chaplin Senior Planner City of Federal Way Community Development Department -12- November 24, 2021 2. A wall mounted FDC is acceptable if desired.
