1. The wet pond drawdown calculations use an incorrect flow rate, resulting in a drain time
greater than 5 days.
2. Please provide calculations showing that the inlet into the wet pond and the outlet from
the wet pond are designed to prevent erosion during peak flows from the 10-year storm.
3. Provide pdfs of all revisions, 2 hardcopies of revised plan sheets, and 1 hardcopy of other
documents. Pdfs must be uploaded using the form at:
