Indicate the emergency overflow elevation and location of the existing wetlands and pond on the plan. As stated above, the emergency overflow has been established on Pheasant Run South and is shown on the revised plans.

Ensure that the low opening of existing homes and proposed lots adjacent to Pond 1P and the existing wetland upstream of the 3' x 6' box culvert are 1' above the emergency overflow elevation. Update the emergency overflow elevation at the low point of Pheasant Run South on the grading plan to the elevation of the top of curb or centerline of the road, whichever is greater. 7. Low floor elevations for lots located on Pheasant Run South are required to be a minimum of 2' above the 100 -year elevation of the existing wetland. The RCWD has indicated that the HWL in the wetland area of this project is 892.0. The low floor elevations of the lots in question are a minimum of 2' above that elevation.
