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: Bev Malan Project: 40 Lot Subdivision Project Location: Longmire St (T/P 21724340000) Yelm, WA 98597 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. Durant Road is classified as a “Neighborhood Collector.” This roadway would be required to have 2 – 12 foot drive lanes and 2 foot paved shoulders for access to this site. This improvement will be required to satisfy the code for the requirement of 2 accesses to the subdivision. Longmire St. is classified as a “Neighborhood Collector.” This project will be required to construction half street improvement along the frontage of Longmire St. Your improvements will be measured from the centerline of the right of way. If this project does not leave at least 14’ of pavement in the drive area opposite your half street improvements, you will have to widen the roadway to meet these requirements. 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’. Sewer The proposed site is currently located in the City of Yelm’s sewer system service area but is not connected to the sewer system. An existing 4” sewer main is located approx. 60’ west of the intersection of Longmire St SE and Berry Valley Dr.  TC \l1 "This project will be required to connect to this sewer main and extend it up to and across this project’s 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 city is reviewing another sewer tank concept that may be a requirement at the time of this application. This concept is meant to connect 5 houses to one step tank instead of each house having one tank. Residential sewer connections are based on a consumption rate of 900 cubic feet a month and are charged at a rate of $5,269 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, bioswale 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 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 is currently located in the City of Yelm’s water system service area but is not connected to the water system. This project will be required to connect and to extend the water main across its frontage. This project will also be required to install water main, fire hydrants, and water meters along all new proposed roadways within the subdivision. The minimum size water main is 8” in diameter within the project limits. The 6” existing water main is located in Longmire St. The location is approximately 200 feet west of the intersection of Berry Valley Road and Longmire St. This water main will have to be extended to serve this project. The water main extension will be 8’ in size. The project engineer will have to provide fire flow calculations demonstrating the ability to serve this project. Residential 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. Each residential unit would be charged for one connection. 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.
