First part of this series covers different design ideas for handling urban runoff on single family, multi-family and commercial developments. This is part 2.
Continuing from the Santa Monica Urban Runoff Management Program, this section covers their worksheet for a variety of construction activity or for voluntary participation.
Check with your local city to determine their stormwater treatment requirements on new or redeveloped construction. In some cases, changing 2,500 sq ft of pervious ground to 2,500 sq ft of impervious ground can trigger the need for stormwater treatment construction at the job site. The Federal Clean Water Act, enforced by the State Regional Water Boards mandates this requirement. In many cases, a regional “Municipal Regional Permit” will hold the design requirements for following through.
