To Whom It May Concern:
The Community Development Department has performed a preliminary review of your environmental checklist for the above referenced project and requires further information before we can
complete our environmental review.
We are requesting more information on the proposed stormwater plan. A Leaf Compost Filtration System is not an approved City of Yelm treatment device. To date, the City has only approved
Vorctechs and Aqua swirl emerging technologies that have received general approval by Department of Ecology. Please resubmit a stormwater plan that is approved by the City of Yelm stormwater
manual.
The proposed Geological/Geotechnical Assessment does not account for the varying groundwater conditions and soil moisture contents that result from changes in the season and precipitation
levels. Please provide a Hydrogeologic report that is prepared by a licensed Hydrologist illustrating that the bottom of the infiltration pond will be six feet above the currently existing
high groundwater levels resulting from the most recent period of prolonged precipitation.
In addition, please provide the associated fees for the Binding Site Plan application which were not originally collected at the time of submittal. The fee for a Binding Site Plan is
typically $350.00 + $50 per unit. You will be charged at 50 percent of the actual cost which is in the amount of $900.00. Please submit a check for this amount along with the required
information above to the Community Development Department.
If you have any questions, please contact me at (360) 458-8430.
Sincerely,
Nisha R. Box
Assistant Planner
