Post-construction stormwater management for a project may be as simple as a few stormwater inlets, stormwater pipes or other methods of stormwater collection and conveyance. However, more complex stormwater drainage systems may have to include facilities to detain and slowly release stormwater as well as facilities to remove a certain amount of pollutants from stormwater before it is released back into the environment.
Land Disturbance less than one acre
For projects disturbing land areas that total less than one acre, all applicable stormwater management regulations apply with the exception of the water quality regulations.
Land Disturbance one acre or greater
