Stormwater Facility Maintenance & Inspection
The Stormwater Facility Maintenance Program is responsible for inspecting and ensuring maintenance of all public and private stormwater management facilities within Montgomery County. It is vital that the structures be maintained in working order so they function as intended, providing protection and stormwater management for our parks, schools, and businesses. The program is paid for by the Water Quality Protection Charge.
What are Stormwater Management Facilities?
Stormwater facilities have two functions:
Stormwater facilities help to slow the stormwater down and clean it before it is allowed to discharge into local streams, which helps to safeguard our waterways. They are vital infrastructure in the urban environment. The State of Maryland regulates the management of stormwater facilities to prevent stormwater pollution in our waterways.

Inspection and Maintenance
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 and need regular maintenance to prevent problems. When this valuable infrastructure functions well, stormwater management can:
The Stormwater Facility Maintenance Program inspects stormwater facilities at least every three years. There are more than 7,000 stormwater facilities in the County that require inspection.
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.
Who can Maintain Stormwater Facilities?
All stormwater facility maintenance contractors working in Montgomery County are required to have a Certificate of Attendance from the Department of Environmental Protection's Stormwater Facility Maintenance Contractor Training. Once contractors have been certified, they will be placed on a list of contractors approved by the County for maintenance of stormwater facilities.
Where are the County's Stormwater Facilities?
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. Look for your property on the map!

Environmental Site Design/ Low Impact Development (ESD/LID) practices are smaller practices meant to capture the stormwater runoff from roofs, driveways, and parking lots on the same property. Overall maintenance is routine landscaping and removing tree debris and trash. Some of these practices are RainScapes.
Stormwater Ponds can have both structural and non-structural maintenance. Learn more about stormwater ponds.
Belowground Stormwater Facilities
Belowground Stormwater Facility maintenance fact sheets describe typical structural maintenance, such as power-washing, removing sediment and debris, and replacing filters.
Easements and Maintenance Agreements
A property owner of any stormwater management system is required to have an easement and maintenance agreement with the County for the stormwater management systems.
The table below provides links to blank easement and covenant documents. Developers and property owners should use these documents when creating new easements and covenants for their stormwater facilities. The easement and covenant templates are used on all stormwater facilities throughout the County and should not be modified. There are specific documents for residential and non-residential properties.
Because stormwater easements and covenants are legally binding documents, all property owners of stormwater management systems should have a copy of the stormwater easement and covenant for their property. Developers should provide these documents to the property management company or HOA after transferring ownership.
If you need to obtain a copy of the recorded stormwater covenant or easement for your property, please visit the Montgomery County Circuit Court Land Records Department or search online at the Maryland Land Records.
Maintenance Transfer Program
If you own a stormwater facility and would like to transfer it into the County's Stormwater Facility Maintenance Program, use the guidance outlined here.
The transfer process has three stages:
Once you have completed these stages, the County becomes responsible for structural maintenance of the facility, such as leaks, stone replacement or replacing concrete and pipes. You (the property owner) however, remain the owner of the facility and continue to be responsible for non-structural maintenance around the facility, such as trash removal, grass cutting, and landscaping.
DEP highly recommends that you contact the Department before you submit your transfer paperwork to ensure that all the necessary documents have been prepared and to learn more about the transfer process. Residential and select non-residential facilities are eligible for transfer into the County's maintenance program.
NOTE: Although DEP encourages homeowners' associations to submit transfer documents as soon as possible, transfer documents will not be forwarded to the County Administrative Officer until the facility has an approved final inspection and the facility is in as-built condition. However, DEP review of the transfer documents can occur concurrently with repair work to bring the facility to as-built condition.
A variety of documentation is required for the transfer. This documentation helps to ensure that you are the verified owner and that the former owner (in many cases the developer) transferred the common area property, such as the stormwater facility, as required. The documents required include:
Use the following outline as a guide for gathering the appropriate information for the application:
Do You Need Help?
DEP is happy to assist you with this process. Please email us at email@example.com or call 311 and provide the location of the stormwater facility. DEP can provide the structure type, the facility number, and insight into what to expect during the transfer process.
Once most or all of the information described under Stage 1 has been collected, fill out the Stormwater Facility Maintenance Transfer Application form. Instructions for filling out the form are available. You must complete, sign, and notarize all the appropriate transaction documents, such as grants of easement, declaration of covenants, or covenant amendments. Submit the application form and supporting documents for legal review by DEP and the Montgomery County Office of the County Attorney.
After legal review and certification, the County Attorney returns the documents to DEP for submission to the County Administrative Officer. After the County Administrative Officer has signed the documents, DEP returns the fully executed documents to you so they can be recorded in the land records (see below).
Once DEP returns the fully executed documents to you, the transfer process is almost finished. All that remains is for the signed documents to be recorded at County Land Records. You must record the document with County Land Records and receive a certified copy. Be sure to record only documents that have been signed and approved by the County. You can obtain a certified copy of a recorded document by taking a document that has been numbered and indexed to Room 219 of the Judicial Center at 50 Maryland Avenue in Rockville, Maryland.
The official approval letter will not be sent out until you obtain a certified copy of the recorded documents from County Land Records and submit the copy to DEP. Once DEP receives the certified copy of the recorded documents, Montgomery County becomes the only entity responsible for structural maintenance of the stormwater facility.
The time needed to complete the full transfer process varies depending on:
Before submitting your application to DEP, contact us at firstname.lastname@example.org or call 311 to confirm that you have all the information you need to submit an application.

Stormwater facilities that are functioning as they were designed will not cause mosquito problems. Most facilities, except wet ponds, are designed to drain within 72 hours. DEP has developed a webpage and brochure with all the information you need to identify if mosquitoes are coming from a mal-functioning stormwater management facility and how to prevent these issues. The webpage also contains general information on mosquito biology and prevention.
