MCD retarding basins are designed to store a defined amount of water. For the flood protection system to work properly, MCD must maintain the storage capacity in the retarding basins. Certain activities and land uses require a permit. Prior approval is required.
MCD may issue a Retarding Basin Permit for temporary or permanent structures or uses within a retarding basin. The structure or use may not adversely affect the storage capacity of the retarding basin; or MCD’s ability to enter, inspect, or monitor the property.
MCD may issue a Recreational Vehicle Permit to allow the temporary placement of a travel trailer, truck camper, or motor home within a retarding basin. Recreational Vehicle permits are valid only between May 1st and November 1st.
