Ian,
I have run drawdown calculations for the wet detention pond and they are within the allowable range per the BMP
Manual.
Your site visit with Joe showed the maintenance on the pond to be satisfactory.
Therefore, I have no further engineering concerns with this project and I approve the engineering design.
Thanks,
Annette
