well and allow the lakes to support the designated uses<br />
assigned to them. This project will serve as a city-led<br />
example of a stormwater retrofit for a 6.8 acre tributary<br />
area that can be replicated on a smaller scale by private<br />
property owners. Native plantings installed with the<br />
proposed BMP will facilitate bioretention and plant<br />
uptake. The filtration basin includes a drain-tile due to<br />
poorly draining soils. However, the proposed engineered<br />
mix of sand and compost within the basin will provide<br />
water quality treatment of the lawn and impervious<br />
runoff.<br />
Buffalo Creek – Marsh Water Project – 2014<br />
Sponsor: Buffalo Creek <strong>Watershed</strong> District<br />
Funding: Clean Water Partnership (Grant) $10,000 and<br />
Clean Water Partnership (Loan) $294,540<br />
Purpose: The Marsh Water Project includes the<br />
construction of a stormwater wetland BMP, placed<br />
in-line with the existing ditch, to treat stormwater from<br />
agricultural, industrial, and residential land uses. Since<br />
few (if any) vegetative buffers, ponds, or other BMPs<br />
exist along the drainage system, nutrient concentrations<br />
are relatively high at the proposed BMP site, enabling<br />
substantial reductions as a result of the BMP through<br />
both particle settlement and absorption from the<br />
wetland plantings. Total anticipated yearly pollutant<br />
removals for the stormwater wetland BMP is 23 tons of<br />
TSS and 67 pounds of TP.<br />
