The outlet structure needs final work in converting it from the sediment basin design during the construction phase to the current wet detention basin design for post construction. The bare soil areas around the pond and swaie need to be vegetated within 7 -14 days. Top soil, sod and/or grass seed, stabilization matting and fertilizer will need to be added to these areas in order to get a good cover of grassed vegetation to keep the slopes stabilized.

After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).
