"Chip" Vincent, Administrator January 9, 2019 Hans Korve Planning Manager, DMP 726 Auburn Way N Auburn, WA 98002 VIA Email: hans@dmp-inc.us RE: Wilson Park II Mr. Korve, Thank you for sending over the revised construction drawings for Wilson Park II. Based on the our very preliminary review of the adjusted plan set you will need to submit a formal revision to your previously approved plan set, construction plans for Safe Route to school, as well as a Final PUD submittal. Reviews of the Final PUD and the Civil Construction Revisions will be concurrent. Please set up an intake appointment for the Civil Construction Revisions with Justin Johnson (425-902-7102) and for the Final PUD with Vanessa Dolbee (vdolbee@rentonwa.gov). We reviewed the materials that you provided at a very preliminary level and noted the following corrections and/or missing information that need to be addressed prior to acceptance of your revised construction plan submittal. Our preliminary comments and required items are noted below: 1. The construction plans shall be revised to provide shared driveways for all but two lots to reduce the number of curb cuts in the project. Lots with shared driveways shall be accessed from the rear (off of the proposed shared driveways). Easements for each of the driveways will need to be recorded on the plat. 2. The City will accept a hammerhead turn around within lots 6 and 7 as long as it meets the requirements of Renton Fire Authority for turn arounds. 3. Underground utilities (proposed water line) are permitted within the Urban Separator provided they are located underground and the surface is revegetated and pervious. Revise the construction plans accordingly. 4. Disturbance to the Urban Separator should be reduced to the maximum extent possible. As such only the water line necessary for Wilson Park II will be allowed to be constructed, and water lines should cross perpendicular to reduce the linear footage of impact. Revise the construction plans accordingly. 5. No development is permitted on Protected Slopes (slopes 40% or greater), this includes any new water lines and/or grading for the road or lots. Please identify areas of Protected Slopes to ensure the off -site site work will not be located within a Protected Slope. 6. The creation of Protected Slopes is not permitted, no grades shall be created that exceed 39.9%. Construction plans shall be evaluated and show that protected slopes are not being created. 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov Mr. Hans Korve January 9, 2019 page 2 A fence detail is required to be provided and is not in the plan set. In addition the fence shown on the plan set is not in the correct location. Revise location of split rail fence on the construction plans to be located along the edge of the Protected Slope. It is unclear where the Protected Slopes are located on the site on sheet 3 of the plan set (Offe Grading/Erosion Control Plan). This should be added to the plan set to ensure the retaining walls and trail are located in the right location and do not encroach into the Protected Slopes. Lighting is required along the pedestrian path and at the pergola. This lighting plan was to be included with the construction permit and was not included in the material submitted. This is required as part of the revision submittal. 10. The Community Space is required to add a recreational amenity. The staff report suggested elements such as a BBQ area, fire pit, or community garden. Only a pergola is proposed in the provided plan set which is insufficient as a Community Space. Amendments to the plans shall show compliance with this requirement. Furthermore, it appears a portion of the Community Space is located within the Protected Slope, this should be redesigned to not encroach into the Protected Slope. 11. The plans call for the Safe Route to School along South 55th Street to Talbot, with a reference to a separate civil construction permit (Condition of Approval #8). Construction plans for this walkway shall be submitted with the revision submittal. 12. A Final PUD is required to be submitted with the revision submittal and needs to be processed and approved prior to Civil Construction Permit Issuance. Please note that the Final Plat and PUD will expire if construction is not completed and the Final Plat recorded by July 5, 2019. Once the project is completed you will need to submit a clean set of final record drawings (as-builts) which would only include the information of what was constructed in the field. Thank you, —6 Jennifer Henning, AICP Planning Director 1055 South Grady Way, Renton, WA 98057 • rentonwa.gov
