and fallen trees (see site pictures at end of memorandum). asea on this determination,the lateral
<br /> recession to was estimated to be 0.3 Styr,which is on the low and of the'severe' range(0.3- 0.5
<br /> Styr). Assuming sandy soils, the estimated soil loss from this 350' stretch of bank with an average 2'
<br /> eroding face is approximately 11.6 tons per year. This results in an estimated 9.82 pounds of total
<br /> phosphorus contributed to Centerville Lake and downstream waterbodles,annually. Stabilization of the
<br /> bank will result in 100 percent reductions in these estimated pollutant leads.

<br /> STAFF NOTES
<br /> While the grant request amount exceeds the standard maximum funding forte GOING Water Quality
<br /> Grant Program, this project spans 350 linear feet, which represents approximately 3.5 standard
<br /> properties(100 linear feet).
<br /> The alternative of using fieldstone (river rock) is more expensive than trap rock, but it still be more
<br /> natural looking along the shoreline, Therefore, it is recommended.
<br /> The City of Centerville is excited and highly motivated to complete this project. They are proactive and
<br /> eager to improve water quality and stabilize the bank.
<br /> RECOMMENDATION
<br /> Approve Water Quality Grant Program application for cost-share up to$11,210.00.
