Provide a note requiring that all temporary controls be removed within 30-days once no longer needed; trapped sediment must be removed and stabilized. Provide adequate protection from erosion and sediment deposition for downstream properties and waterways. Demonstrate that concentrated stormwater runoff leaving the site discharges directly into an adequate natural or manmade channel. Demonstrate that two (2)-year runoff from the site does not overtop banks of natural channels and does not cause erosion. Demonstrate that discharge into the previously constructed man-made channels are not overtopped by a ten (10)-year storm and the two (2)-year storm does not cause erosion Demonstrate that closed storm sewer systems contain the ten (10)-year storm. Provide calculations and show ten (10)-year HGL in the storm sewer profiles.

Provide energy dissipaters at the outfall of all detention facilities. Provide calculations demonstrating that onsite ditches are adequate. All sheet flow leaving the site shall be at or below pre-developed rates or it must be diverted to an adequate channel, pipe system or detention facility. All calculations and assumptions shall pertain to the entire development and its ultimate build-out. All measures utilized shall minimize the impact on waters of the State.
