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-lot plat proposal, located east of and adjacent to Vesta Ave NE (156th Ave SE), west of and adjacent to Yakima Ave NE (158th Ave SE), and on the NE 1st St grid line in Sect. 14, Twp 23N Rng 5 E. 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 and 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 Vesta Ave NE. See City of Renton sanitary sewer drawing #S-3338 for details. There is an existing 8” sewer main in Yakima Ave NE. See City of Renton sanitary sewer drawing #S-3148 for details. Project plans need to show how sanitary sewer will be provided to each unit with an individual sewer service line. Per code, the project needs to extend sanitary sewer along the full frontage of the parcel being developed. This proposal is located in the Central Plateau Interceptor Area Special Assessment District (SAD 0034). These fees are $351.95, plus interest, per unit and shall be paid at the time a construction permit is issued and prior to recording the plat. Sanitary Sewer system development (SDC) fees 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 frontages of the parcel being developed. The street improvements on Vesta Ave NE shall be a 5-foot bike lane, curb 17 feet from centerline of right-of-way, followed by an 8-foot planter strip, and a 5-foot sidewalk. Additional right-of-way not required for this. The street improvements on Yakima Ave NE shall be a 32-foot pavement to allow for parking on both sides, curb 16 feet from centerline of right-of-way, followed by an 8-foot planter strip and a 5-foot sidewalk. Additional right-of-way not required for this. The new internal street shall be extended the full width of the development connecting to both Vesta and Yakima Ave NE. The street shall have a 26-foot pavement section, allowing parking on one side, an 8-foot planter, and 5-foot sidewalk in a 52’ dedicated right-of-way. Street lighting shall be per current City of Renton standards and specifications. Residential style LED Luminaires spaced approximately 110’ is required internally to the proposed plat and on 158th; Cobra type or other arterial luminaires as approved by the City of Renton will be required on Vesta. See City of Renton details. Per City of Renton code, all lot corners at intersections of dedicated public rights-of-way shall have a minimum radius of fifteen feet (15’). All new electrical, phone, and cable services and lines must be undergrounded. 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; these fees are approximately $750 per lot at this time. A limited traffic study evaluating the 156th access intersection turning movements and sight distance is required. STORM DRAINAGE: There are existing storm drainage facilities in both Vesta and Yakima Ave NE. See drawing #S-4031. 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. This site is located in the Flow Control Duration Standard Forested Conditions. Surface Water SDC fees are $1,012 per lot if individually owned or $0.405 per square foot of new impervious area if not individually owned lots. 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.
