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 steel water main in N. 24th Street. Available fire flow from the 6-inch water main is 750 gpm. 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 and capable of delivering 1,000 gpm. 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 fees for water will be based on the size of each new domestic water meter that will serve the new homes on each new lot. Since the new homes will be required to be sprinklered, a minimum of 1-inch water meter will be required for each home. Fees for a 1-inch meter $5,589.00. The existing home at 1415 – N. 24th Street is served by a ¾” water meter. Partial credit will be given for the existing home. 5. The fee for a 1-inch meter installed by the City is $2,430.00. Sanitary Sewer 1. Sewer service will be provided by the City of Renton. There is an 8-inch sewer main in N. 24th Street. 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 fees for a 1-inch water meter are $3,977.00. Partial credit will be given for the existing home. Payment of these fees will be required prior to issuance of the utility construction permit. Storm Drainage 1. There are no storm drainage improvements in the area. 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.

There are no existing street improvements fronting the site in N. 24th Street. Existing right-of-way width in N 24th is 30 feet. To meet the City’s minimum street standards, up to 7 feet will be required to be dedicated to the City for additional right of way along the project side. Street improvements fronting the site will include a minimum pavement width of 18 feet, an 8-foot planting strip, and 5-foot sidewalk. This will provide a road section of 31 feet. Internal roadway shall be a minimum pavement width of 20 feet. Final street improvements will be determined at preliminary approval. Since there are no street improvements in the area, an application requesting a waiver may be submitted to the City for consideration 2. Street lighting is not required. 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.
