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 proposal. The following comments are based on the pre-application submittal made to the City of Renton by the applicant. Water Water service is provided by the City of Renton. There is an existing 8-inch water main in NE 7th Street. The proposed project is located in the 565 water pressure zone and is outside the Aquifer Protection Zone. 2. Extension of an 8-inch water main and a minimum of one hydrant will be required on site. All new construction must have a fire hydrant capable of delivering a minimum of 1,000 GPM and must be located within 300 feet of the structures. 3. The system development fee for water is based on the size of the new domestic water meters that will serve the new homes on the new lots. Fee for ¾-inch water meter install is $2,236.00. Credit will be given for the water meter connected to the existing home. 4. Fee for a ¾-inch meter installed by the City is $2,260.00. Sanitary Sewer Sewer service is provided by the City of Renton. There is an 8-inch sewer main in NE 7th Street; however, it’s approximately 150 feet west of the site. Extension of the 8-inch main in NE 7th Street, as well as into the short plat, will be required. If the existing home is currently on a septic system, it will be required to be abandoned in accordance with King County Department of Health. The system development fee for sewer is based on the size of the new domestic water to serve the new home on the new lot. Sewer fee for a ¾- inch water meter install is $1,591.00. This parcel is subject to a Special Assessment District. The East Renton Interceptor fee is $316.80 per lot. Payment of these fees will be required prior to issuance of the utility construction permit. Storm Drainage 1. There is no formal storm conveyance system in NE 7th Street. 2. A drainage plan and drainage report will be required with the site plan application. The report shall comply with the 2009 King County Surface Water Manual and the 2009 City of Renton Amendments to the KCSWM, Chapter 1 and 2. All core and any special requirements shall be contained in the report. Based on the City’s flow control map, this site falls within the Flow Control Duration Forested Conditions. The drainage report will need to follow the area specific flow control requirements under Core Requirement #3. 3. A covenant for storm water drainage facilities will be required. 4. A geotechnical report for the site is required. Information on the water table and soil permeability with recommendations of appropriate flow control BMP options with typical designs for the site from the geotechnical engineer shall be submitted with the application. 5. A Construction Stormwater Permit from Department of Ecology is required if clearing and grading of the site exceeds one acre. 6. The surface water system development fee is currently $1,012.00 for each new lot. Credit will be given for the existing home. Transportation/Street 1. Existing right-of-way width in NE 7th Street is 60 feet. This street has been identified as a residential access street. To meet the City’s new complete street standards, street improvements fronting this site will include 26 feet of pavement, an 8-foot planter strip, 5-foot sidewalk, curb, and gutter. Since it appears there are no existing improvements in NE 7th Street, applicant may submit a request to waive the street improvements. The internal roadway cross-section will consist of a 26-foot utility and access roadway with 20 feet of paving. 2. The maximum width of a single loaded garage driveway shall not exceed nine feet (9'), and a double-loaded garage driveway shall not exceed sixteen feet (16'). 3. The current traffic mitigation fees are $717.75 per new single-family lot. Credit will be given for the existing home. These fees are payable prior to recording of the plat. A fee increase is under discussion with an unknown implementation date at this time. General Comments 1. All construction utility permits for drainage and street improvements will require separate plan submittals. All utility plans shall conform to the Renton Drafting Standards. Plans shall be prepared by a licensed Civil Engineer. Separate permit and fees will be required for the water meter installation, side sewer connection, and storm water connections. A cut and cap permit for the water service may be required. Water services, sewer stubs, and drainage flow control BMPs are required to be provided to each lot prior to recording of the short plat.
