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
