Review comments may also need to be revised based on site planning and other design changes required by City staff or made by the applicant. I have completed a preliminary review for the above-referenced 14-unit cottage PUD proposal, located on the east side of Nile Ave NE in the vicinity of NE 7th Pl, all in Sect. 11, Twp 23N Rng 5 E. The project site is located south of, but not adjacent to, Olympus Villa on NE 7th Pl. The following comments are based on the pre-application submittal made to the City of Renton by the applicant: WATER: This site is not located in the City of Renton water service boundary; it is located in the Water District 90 area. A Certificate of Water Availability is required and shall be submitted prior to formal application. This site is not located in the Aquifer Protection Zone. The project will need to provide domestic and fire service to serve the proposed development. Per the City Fire Marshal, the preliminary fire flow requirement for a single family home is 1,000 gpm minimum for dwellings up to 3,600 square feet (including garage and basements). If the dwelling exceeds 3,600 square feet, a minimum of 1,500 gpm fire flow would be required. A minimum of one fire hydrant is required within 300-feet of the proposed buildings and two hydrants if the fire flow goes up to 1,500 gpm. Lateral spacing of fire hydrants is predicated on hydrants being located at street intersections. All fire hydrants need to be brought up to current code if not existing. SANITARY SEWER: This site is located in the City of Renton sanitary sewer service boundary. There is an existing 8” sewer main in NE 6th Pl. See City of Renton sanitary sewer drawing #S-3187 for details. There is an existing 8” sewer main in the parcel south of and adjacent to this parcel. See City of Renton sanitary sewer drawing #S-3004 for details. Plans need to indicate how sanitary sewer will be provided to each unit with an individual sewer service line. Per code, sanitary sewer needs to extend along the full frontage of the parcel being developed. This proposal is located in the East Renton Special Assessment District (SAD 0002). These fees are $316.80 per connection and shall be paid at the time a construction permit is issued. Sanitary Sewer System Development Fees (SDC) are based on the size of the domestic water meters. These fees are collected at the time a construction permit is issued. STREET IMPROVEMENTS: The project shall be required to install curb, gutter, sidewalk, and street lighting on the full frontage of the parcel being developed. The proposed internal street does not meet current standards for either private or public streets. The project cannot be approved with the proposed configuration without access in compliance with City codes. All new electrical, phone, and cable services and lines must be underground. The construction of these franchise utilities must be inspected and approved by a City of Renton public works inspector prior to recording the plat. Traffic mitigation fees apply. STORM DRAINAGE: There are existing storm drainage facilities in Nile Ave NE. See City of Renton drawing # R3187. A conceptual drainage plan and report is required to be submitted with the formal application for the project. A drainage control plan designed per the King County Surface Water Manual 2009 is required. The conceptual storm drainage plan needs to address how the roof runoff from the new lots will be handled. The Surface Water SDC fees are $1,012 per lot if individually owned or $0.405 per square foot of new impervious area if lots are not individually owned. These fees are collected at the time a construction permit is issued. GENERAL:  All required utility, drainage, and street improvements will require separate plan submittals, prepared according to City of Renton drafting standards, by a licensed Civil Engineer.  All plans shall be tied to a minimum of two of the City of Renton Horizontal and vertical Control Network.  Permit application must include an itemized cost estimate for these improvements. Half of the fee must be paid upon application for building and construction permits, and the remainder when the permits are issued. There will be additional fees for water service related expenses. See Drafting Standards.
