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 City to build an Aerospace Training Center at the old Renton Chamber of Commerce building site on the airport, located in Sect. 7 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 located in the City of Renton water service areas. The site is not located in the Aquifer Protection Zone. There is an existing 12” DI water main located on the Airport on West Perimeter road. See City of Renton drawing number W 858. This main can provide 2,000 GPM. There is an existing ¾” domestic water meter off of the main in West Perimeter Road. There is an existing 12” DI watermain in Rainier Ave S. See City of Renton water drawing #W0199 for details. This main can provide 2500 GPM. The site is located in the 196 water pressure zone. The static pressure is approximately 60 psi at the building pad level. Construction of a commercial building will trigger a separate review. The existing fire hydrants may need to be fitted with stortz fittings to bring them up to current City code. Per the City of Renton Fire Marshal the building may be required to be sprinklered if the center exceeds 5,000 square feet. The Water System Development Charges are based on the size of the (each and all) water meter(s). These fees are collected at the time a construction permit is issued then prior to the issuance of the building permit. Sanitary Sewer There is an existing 8”sanitary sewer main on the Airport site, on West Perimeter Rd. See City of Renton drawing S-1688. The existing building is connected to sewer with a side sewer coming out of the front of the building then to the north then down the hill (east) to the existing sewer main in West Perimeter Rd. The site is not located in any Special Assessment Districts or any Latecomers boundary. The Sanitary Sewer System Development Charges are based on the size of the domestic 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. Storm Drainage There are existing storm drainage conveyance pipes and facilities in Rainier Ave N. A storm drainage report may be required. All storm drainage shall be in compliance with the City of Renton amendments to the 2009 King County Surface Water Drainage Manual. Storm System Development Charges are $0.405 per square foot of new impervious surface area. These fees are collected at the time a construction permit is issued. Street Improvements Additional street improvements will not be required. Traffic Mitigation fees do not apply. A traffic study will not be required. General Comments 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 may be additional fees for water service related expenses. See Drafting Standards.
