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 for the Washington State Auto Dealers Headquarters at the southeast corner of the intersection of SW Grady Way and Raymond Ave SE in Section 19, Township 23N, Range 5E. The following comments are based on the pre-application submittal made to the City of Renton by the applicant. Water 1. This site is located in the City of Renton Water service area. 2. This project site is located in the 196 Water Pressure Zone. The static water pressure at the street level is about 75. 3. There is an existing 12” DI watermain located in Raymond Ave SW and in SW Grady Way. See City of Renton water drawing W1904 as-built for details. 4. The project will need to provide domestic service with a Reduced Pressure device in a Hot Box, irrigation service and fire service with a DDCVA. 5. Per the City Fire Marshal, the fire flow requirement is 1,500 gpm based on a fully fire sprinklered building. A minimum of two fire hydrants are required. One fire hydrant is required within 150-feet of the proposed building and one hydrant is required within 300-feet. This distance is measured along the travel route. Existing hydrants can be counted toward the requirement as long as they meet current code. The existing hydrants all need 5-inch storz fittings in order to meet code and they do not have them at present. It appears adequate fire flow exists in this area. One new hydrant will be required within 50-feet of the fire department connection. The number of additional hydrants required is dependent on the calculated fire flow. 6. The Water System Development Charges are based on the size of the (each and all) water meter(s). These fees are triggered by an additional water or upsizing an existing water meter. These fees are collected at the time a construction permit is issued, if there is no construction permit then prior to the issuance of the building permit. Sanitary Sewer 1. A commercial building permit will trigger a separate review. 2. There is an existing 12” sanitary sewer main in Raymond Ave SW and an existing 12” in the alley adjacent to the south property line. 3. The proposed project needs to show how they propose to serve the new development with sanitary sewer service for a commercial site (minimum 6” in diameter). 4. Any use in the building subject to oils or grease shall require the installation of a grease interceptor or oil/water separator as determined at the time of plan review. 5. The Sanitary Sewer System Development Charges are based on the size of any and all domestic water meter(s). These fees are collected at the time a construction permit is issued, if there is no construction permit then prior to the issuance of the building permit. Storm Drainage 1. A conceptual drainage plan and report is required to be submitted with the formal application for a commercial project. A drainage control plan designed per the 2009 King County Surface Water Manual is required. 2. The Surface Water SDC fees are $0.405 (but not less than $1,012) per square foot of new impervious area. These fees are collected at the time a construction permit is issued. Street Improvements 1. Construction of a commercial building will trigger a separate review. 2. Street improvements will be required to be installed across the full frontage of both SW Grady Way and Raymond Ave SW. 3. Staff would support a street modification request for a 5’ sidewalk and 8’ planter strip on SW Grady Way. 4. There is existing street lighting on SW Grady Way. 5. Additional right-of-way is not required on SW Grady Way. 6. There is no existing curb on Raymond Ave SW. The street section on Raymond Ave SW requires a curb set 18’ from centerline, a 7’ planter strip, and a 5’ sidewalk. General Comments 1. 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. 2. All plans shall be tied to a minimum of two of the City of Renton Horizontal and Vertical Control Network. 3. 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 permits are issued. There will be additional fees for water service related expenses.
