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. Water 1. Water service will be provided by the City of Renton. There is a 6-inch cast iron water main in NE 25th Place. Available fire flow from the 6-inch water main is 1000 gpm. The project is in the 565 water pressure zone. 2. 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 all structures. There is a fire hydrant in the vicinity that may be counted towards the fire protection of this project, but is subject to verification for being within 300 feet of the nearest corner of all buildings. Location will require fire department approval. 3. Existing hydrant(s) counted as fire protection will be required to be retrofitted with a 5” quick disconnect storz fitting if not already in place. 4. 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. Fee for a 1-inch meter is $5,589.00. Credit will be given to the existing home. 5. Fee for a ¾-inch meter installed by the City is $2,260.00. Fee for a 1-inch meter installed by the City is $2,430.00. 6. If the applicant proposes to keep the existing home and create a two-lot short plat, a new hydrant may be required and a new water meter may be installed at the street for the new lot to the rear. If the applicant proposes to remove the existing home and create a 3-lot short plat, then a minimum of a 4-inch water main, and up to an 8-inch water main, will be required to be extended onsite. Sanitary Sewer 1. Sewer service will be provided by the City of Renton. There is an 8-inch sewer main in NE 25th Place. 2. System development fees for sewer are based on the size of the new domestic waters to serve the new homes on the new lots. Sewer fee for a ¾- inch water meter install is $1,591.00. Fee for a 1-inch meter is $3,977.00. Credit will be given for the existing home if it is connected to sewer. Payment of these fees will be required prior to issuance of the utility construction permit. 3. If the applicant proposes to keep the existing home and create a two-lot short plat, a new sewer stub in NE 25th Place, extended within six feet of the property line of the new lot, will be required. If the applicant proposes to remove the existing home and create a 3-lot short plat, separate side sewer stubs may be provided to each lot. Storm Drainage 1. There is a 12-inch storm drainage conveyance system in NE 25th Place. 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, Chapters 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 Standard, Forested Conditions. The drainage report will need to follow the area specific flow control requirements under Core Requirement #3. This project may be subject to Appendix C, Small Project Drainage Requirement only. 3. 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. 4. A Construction Stormwater Permit from the Department of Ecology is required if clearing and grading of the site exceeds one acre. 5. Surface Water System Development fees are $1,012 per each new lot. Credit will be given for the existing home. This is payable prior to issuance of the construction permit. Transportation/Street 1. There are no existing street improvements fronting the site in NE 25th Place. Existing right-of-way width in NE 25th Place 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 a pavement width of 26 feet, an 8-foot planter strip, 5-foot sidewalk, curb, and gutter. 2. Street lighting is not required. 3. Private access roadway shown under the 3-lot short plat proposal shall be a minimum roadway width of 26 feet, and 20 feet of paving. 3. Current traffic mitigation fees are $717.75 per new single-family lot. Credit will be given to the existing home. These fees are payable prior to recording of the plat. A fee increase is anticipated in 2014. 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. When the utility plans are complete, please submit three (3) copies of the drawings, two (2) copies of the drainage report, permit application and an itemized cost of construction estimate and application fee at the counter on the sixth floor. All subdivisions shall provide water, sewer and storm stubs to each new lot prior to recording of the plat.
