Until a complete application is made, the Community Development Department can only attempt to inform the applicant of general requirements as they appear in the form presented by the applicant at the time of pre-submission. Proponent: Mike McKinnon Project: Multi unit Commercial Project Location: 106 Plaza Dr Yelm, WA 98597 Street Improvements  TC \l1 " No Street Improvements will be required to Plaza Dr. The interior drive aisles and parking shall be consistent with the city’s parking details and the development guidelines. Street improvements may not be limited to above references. The required TIA may also outline additional improvements to the adjacent roadways and intersections. Sewer The proposed site will be required to connect to the City's sewer system. There are existing services extended to this lot from Plaza Drive. The building(s) will be required to install a step sewer tank, pumps etc. A civil engineer licensed in the state of Washington shall submit this design. The STEP system shall be designed and installed per the City of Yelm Development Guidelines. Commercial sewer connections are based on a consumption rate of 900 cubic feet a month and are charged at a rate of $5,417 per a residential connection (fee subject to change) inside city limits. Each residential unit would be charged for one connection. An inspection fee of $145.00 per a STEP sewer system will also be required. These fees are payable a building permit issuance. This property is not included in the City of Yelm Sewer Local Improvement District (LID). Stormwater TC \l1 " Developments with over 5,000 square feet of impervious surface are required to provide stormwater facilities pursuant to the 1992 DOE Stormwater Manual. If stormwater mitigation is required the types of stormwater mitigation may be wet ponds, bioswales and filter strips. The stormwater disposal is 100% infiltration. There are 2 ways to accomplish this: open ponds and underground galleries. The open ponds are depressions that store stormwater and allow it to perk back into the underground aquifer. All building roofs will be directed to underground galleries that are separate from the stormwater treatment system. The Plaza Road detention center was only designed for Plaza Road and Lot 1. All storm water facilities shall be located outside the right of way in a separate tract to be maintained by the homeowners association. At this time sand filters and “alternate technologies” are not permitted as stormwater mitigation. Water The proposed site would need to connect to the City's water system. There is an existing 6” water line located on Plaza Dr. This lot has the services already installed. This project will need to purchase water meter(s) to serve this property. This lot also has a 6” fire line installed to the property line for use as fire hydrant supply and /or fire sprinkler system. Commercial water connections are based on a consumption rate of 900 cubic feet a month and are charged at a rate of $1,500 per a residential connection (fee subject to change) inside city limits. The project engineer shall submit water use calculations to determine the water use this project may consume. This fee is payable at building permit issuance. Irrigation Meter: An irrigation meter shall be installed for the purpose of irrigation. An approved backflow prevention device will be required for all landscape irrigation connections. Cross Connection Control: Washington State Department of Health, in WAC 246-290-490 states that all group A water systems with 1000 or more connections are required by the department of health to develop and implement a cross control connection program. This program requires all commercial buildings and irrigation systems to have a back flow prevention device installed on the water services. A list of approved devices can be located at the above referenced Washington Administrative Code. ADA Requirements The American Disabilities Act required that facilities are ADA accessible. Facility improvements will have to meet current code. Review of these improvements will be determined upon further review of the civil plans.
