Sediment Basin / Trap

Using permanent Stormwater facilities as sed traps is a common component of the E&S plan provided appropriate measure are taken to preserve the infiltration capacity of the sub grade soils. Proper sequencing and construction practices should be followed to ensure that the pond will function in the permanent condition as intended. If this is outside your LEED boundary, is this basin already serving a Stormwater function for a built condition? If that is the case, then this approach may not be acceptable, but you should verify with your local agency that has jurisdiction over Stormwater discharges.
