All "contaminated" runoff from the site <br />is routed into either the East or West ponds. Runoff is routed along the outside of the site via <br />channels. <br />The "rill" erosion throughout the site as a result of the fall storms appears to have been <br />repaired. Snowfall accumulation made a complete inspection impossible but the areas where <br />the ground was exposed appeared to be repaired. The channel along the east side of the <br />property had some sections that were repaired, though the very southern portion appeared to <br />be in need of additional work (see Pic. 1). <br />The north runoff /drain filter located along the west side of the main drive experienced <br />additional erosion along the north bank and needs to be repaired (see Pic. 2). The feature may <br />need to be modified due to the reoccurrence rate at this locale. The collected sediment in both <br />the north and south structures should be removed. <br />P.O.
