A basin or pond constructed to handle excess runoff and
sediment from developed parcel.
Purpose:
Detain water and retain sediment that is associated with
runoff from developed parcel.
Criteria:
Must be sized to accommodate the sediment load and excess
runoff above natural predicted runoff. In addition, a primary
spillway and an emergency spillway must be installed to prevent
basin failure.
