Privately maintained stormwater management facilities are maintained by the facility owner.  The county does not have direct maintenance responsibility. 

However, Charles County is still responsible under state and federal stormwater permits for ensuring that the facilities remain in place, operate properly and are functional.  To this end the county has established an inspection schedule for all privately maintained facilities, together with reporting and enforcement procedures for communicating inspection results to facility owners and gaining maintenance compliance. 

Chapter 274-53 of The Code of Charles County, Maryland “Responsibility of owner or occupant”.

“The owner of any property containing a stormwater management system, or any other person or agent in control of such property, shall perform or cause to be performed preventive maintenance of all completed ESD treatment practices and structural stormwater management systems to ensure proper functioning.”
