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. Sewer TC \l1 " The proposed site is currently located in the City of Yelm’s STEP sewer system service area. There is an existing 3” sewer main located in Burnett Road and a 2” sewer line in the dead end road on the south property line. This project will be required to connect to this sewer main and extend it across your projects frontage. This project will also be required to install sewer mains along all new proposed roadways within the subdivision. The sewer main sizes will be reviewed on the preliminary plat application. Each lot will be required to have a step connection box and step sewer service. The proposed development falls in the Killion North LID District and has been assessed a total of 4 ERU’s. The hook up fee of $2,694.00 per an ERU (fee subject to change) is payable at time of building permit issuance. This fee is in addition to the LID assessment of $1,823.15/ERU, which is being paid on an annual basis for 15 years.

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. Fire All projects need to have fire protection for the buildings. To meet this requirement the building must have coverage by fire hydrants. All parts of the buildings must be within 300’ of a fire hydrant. Another means of meeting fire code may be by installing a fire sprinkler system. 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 stormwater facilities will be located in a separate tract that is owned by the homeowner’s association. Street Improvements TC \l1 " Frontage improvements shall be consistent with Yelm’s Development Guidelines. These improvements may consist of asphalt widening, curb and gutter, landscape planter, street trees, sidewalk and street lighting. Burnett Road is classified as a “Neighborhood Collector.” This roadway requires a 16’ paved asphalt section, concrete curb and gutter, planter island, 5’ sidewalk and street lighting. This street classification also does not allow on street parking. Internal plat roads will be classified as a “Local Access Residential.” This roadway requires paved traffic lanes, paved parking lanes, concrete curb and gutter, planter islands, 5’ sidewalk and street lighting. This street classification allows on street parking. The required right of way to be dedicated for the local access roadways is 56’. 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 and architectural plans. Additional Site Planning Notes: The accesses from the neighborhood collector must be designed per the City of Yelm detail 4-8B. The length of the local access roadway will require some type of traffic calming device to help control the speed of the traffic. An example may be a mid block detail similar to the design of detail 4-8B.
