2.6  Control of Construction Runoff

Return to Phase II Storm Water Management Plan

Under the Phase II regulation, this measure applies to construction sites greater than 1~acre and less than 5~acres since the Phase I regulations covered construction sites greater than 5~acres.  As with Phase I, the main aim of this measure is to control erosion from and sediment in construction runoff.

In many cases, the small municipalities covered by Phase II will need to enact new ordinances, or modify existing ones to require control of construction runoff as a condition of project or site approval.  The measures could include preconstruction review of site plans for storm water runoff controls, regular inspections and public access to the construction runoff control plans.  The runoff control measures could include the use of silt fences, temporary detention ponds, hay bales and concrete truck washout areas/devices.
