The following outline provides each of your prescreen comments in italics exactly as written, along with a narrative response describing how each comment was addressed: Email from Jill Ding dated January 24, 2019 From Rohini Nair: 1. Our RMC 4-6-060 and RFA requires cul de sac for dead end access longer than 300 feet. The current plans show dead end access nearer to 430 feet. A modification to this requirement would be required as well as a variance request from the RFA. Response: A modification request is included. A Variance Request to Renton Fire has been added to the submittal package. 2. Also, Please ask for a Groundwater Mounding Analysis to be submitted for the infiltration. Per section 5.2.1 of 2017 RSWDM. Groundwater mounding analysis is generally required for infiltration facilities that serve 1 acre or more of tributary area and have less than 15 feet of separation to a restrictive layer or groundwater table. Response: A groundwater mounding analysis by Earth Solutions NW , LLC is enclosed. Planning Comments: 1. Please name the individual files in accordance with the City’s naming conventions as found in the electronic file standards. Response: File naming has been updated. Jill Ding, Senior Planner City of Renton Community and Economic Development -2- April 4, 2019 2. There were some blanks on the Master Application under row dedication, access easement (access tract) area, and density. Please complete. Response: The Master Application has been completed. 3. Sheet 1 on the short plat plan set had 0 SF listed as the easement area and no density, please update. Response: Sheet 1 has been corrected. 4. The landscape strip between the shared driveway and north property line is required to be 8 feet per RMC 4-6-060J.2, if there is not sufficient area to accommodate the 8-foot landscape strip, a modification to this requirement would be required. Response: A modification request is enclosed. 5. Maximum height of retaining walls shall not exceed 6 feet, north wall appears to have a max height of 11 feet. Response: All retaining walls are 6 feet or less. Additional detail is provided on the plans to demonstrate compliance. 6. Conceptual landscape plan is required, landscape plan shall show minimum 10 feet of onsite landscaping along all public street frontages, 2 trees within the front yards of all lots not abutting a public row, 8 foot landscape strip between the shared driveway and north property line, and 15 feet of landscaping around the perimeter of the stormwater facility within the stormwater tract. Response: Enclosed. 7. Affidavit of posting of public information sign. Response: Enclosed. 8. The retained trees on the southern portion of the project site are required to be placed within a tree retention tract, per 4-4-130H.2. However, there does not appear to be sufficient area to place the trees within the tract and maintain the required minimum lot size of 9,000 sq. ft. If the trees cannot be placed in a tract, due to lot size constraints, a modification to this requirement may be applied for in accordance with 4-4-130I. I would recommend modifying the requirement to place the trees within a tree protection easement instead of a tract, so that you do not have the area counted against the lot area. Response: A Modification Request is enclosed. Email from Rohini Nair dated January 25, 2019 • All portions of the sidewalk should be located in public ROW . Sidewalk should not be in an easement. ROW dedication should be provided accordingly.

Response: An easement and main extension have been added to the plan. o A public sewer easement (of minimum 15 feet width) is required for any public sewer main located outside public right-of-way. It is to be shown and labeled in the utility plan. Response: A 15-foot easement has been added to the plan for the sewer extension along the south property line at Lot 8. • In the drainage TIR – o the special requirement #6 should be mentioned . Currently only 5 special requirements are mentioned. 2017 RSWDM mentions 6 special requirements.
