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.

Are the inlets located per the approved plans? Are the outlet structures located per the approved plans? Comment: The site has recently finished construction and the outlet structure needs to be converted from the sediment basin design to the wet detention basin design with the small diameter orifice with trash gaurds. Also need to check the vegetated shelf and wetland planting plans and make sure the appropriate types and number of wetland plants have been or will be planted around the pond.

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).
