Stormwater facilities can become clogged by trash, debris, sediment and mud, or other stormwater pollutants. The facilities themselves can develop structural cracks and leaks over time. When this valuable infrastructure functions well, it:
The Stormwater Facility Maintenance Program has an Inspection section that inspects all stormwater facilities in the County every three years. The inspection is used to determine a facility's condition and to identify its need for maintenance. Without proper inspections and maintenance, we would not know when a facility has failed. Once a facility fails the cost of repairs are expensive and can result in property damage or other loss. Providing routine maintenance and inspections can keep the stormwater facilities working as intended, save money, property, and protect public safety.

The interactive map below shows all of the County's stormwater facilities. The colored dots represent different types of stormwater facilities. Clicking on a dot will reveal that particular facilities type. Read the next section, "How do stormwater facilities work?", to learn about what the different types of facilities do.
Residential stormwater facility Residential properties: DEP's Stormwater Facility Maintenance Program works with citizens to assume responsibility for structural maintenance for all new residential stormwater facilities and older residential facilities once the property owner has completed the maintenance transfer process. Once the facility has completed the transfer process, DEP will assume responsibility for the structural maintenance and the owner will continue to provide non-structural maintenance to their facility. The facility still is owned by the owner, DEP only assumes the structural maintenance responsibility. Nonstructural maintenance: For all facilities, nonstructural maintenance is the responsibility of the owner. This maintenance includes grass cutting, trash removal, and landscaping.
Nonresidential (e.g., commercial) stormwater facility Maintenance for most nonresidential facilities is the responsibility of the owner. This maintenance responsibility is defined for the owner in the "Designation of Authorized On-site Representative Form" and the signed form must be sent via e-mail to: mcstormwater@montgomerycountymd.gov. Nonstructural maintenance: For all facilities, nonstructural maintenance is the responsibility of the owner. This maintenance includes grass cutting, trash removal, and landscaping.
Local government stormwater facility Montgomery County assumes responsibility for both Structural and Non-Structural maintenance.
