Virginia Stormwater Facility Inspection and Maintenance Requirements

If you own or manage a commercial property or a multi-family community in Virginia, there is a good chance a stormwater pond, underground detention system or other permanent stormwater facility sits on the site. These facilities are stormwater BMPs (best management practices), and notices from the Virginia Department of Environmental Quality (DEQ) call them BMPs. The state's stormwater regulation expects someone to own their long-term care. In most cases that duty is written into a document recorded with the property's land records. It covers maintenance, access for inspections, and reports back to your local stormwater program. Your local stormwater program also has to inspect each facility at least once every five years.

This guide explains what the regulation says and cites each rule by section number so you can read it yourself. It is general information, not legal advice. The document recorded against your property and your local stormwater program have the details for your site.

Who is responsible for maintaining a stormwater facility in Virginia?

Long-term responsibility has to be assigned, and it has to be written down. The regulation states that "the provision of long-term responsibility for and maintenance of stormwater management facilities ... is required," and that these requirements "shall be set forth in an instrument recorded in the local land records" (9VAC25-875-130 B).

In practice, the answer to "who is responsible for maintaining this retention pond?" is in that recorded instrument. It is commonly a recorded maintenance agreement, declaration or covenant. Whoever it names carries the duty. That is usually the property owner (Virginia DEQ Stormwater Handbook, section 10.2.1). A lease can hand maintenance work to a tenant, but it doesn't change the recorded instrument, which runs with the land (130 B2).

What the recorded maintenance document has to include

Under 9VAC25-875-130 B, the recorded instrument must, at a minimum:

Be reviewed and approved by your local stormwater program before the stormwater management plan is approved (130 B1).
"Be stated to run with the land" (130 B2). The duty stays with the property, not with a particular owner.
"Provide for all necessary access to the property for purposes of maintenance and regulatory inspections" (130 B3).
"Provide for inspections and maintenance and the submission of inspection and maintenance reports" to your local stormwater program (130 B4).
"Be enforceable by all appropriate governmental parties" (130 B5).

That fourth item matters because the regulation doesn't only expect the facility to be maintained. It expects the recorded document to provide for inspection and maintenance reports being sent in.

Your local stormwater program reviews and approves this document before it approves the site's stormwater management plan (130 B1), and it is recorded in the local land records (130 B). Some localities require it to be recorded before the plan is approved (Arlington County Code § 60-15 B). Once recorded, it stays in force, so today's owner is bound by it. The key point for owners and managers: inspection reports have to be submitted to your local stormwater program (DEQ, where DEQ runs the program). A completed inspection that never gets filed still leaves the property out of compliance. Exact Stormwater handles the inspection, files the report with your local stormwater program and makes any repairs the inspection turns up.

The Virginia DEQ Stormwater Handbook (section 10.2.6) explains what happens when maintenance falls behind. Enforcement may start with a notice of violation and can move to civil and even criminal penalties in serious cases. In most maintenance agreements, your local stormwater program may also enter the property, make repairs and bill the owner for the cost. Design details for each type of facility are on the Virginia Stormwater BMP Clearinghouse, which lists BMP design specifications.

How often does a stormwater facility have to be inspected in Virginia?

The regulation sets a statewide floor for your local stormwater program. Its inspection program must "ensure that each stormwater management facility is inspected ... at least once every five years" (9VAC25-875-140 C2). The program's inspections must also "be documented by records" (140 C3).

The purpose of that inspection program is stated plainly. It ensures "that permanent stormwater management facilities are being adequately maintained as designed after completion of land-disturbing activities" (140 C). So the standard is the facility as it was designed, not just whether it looks acceptable.

Five years is the minimum for the program's own inspections. Your recorded instrument must also "provide for inspections" and maintenance reports (130 B4). Check it for any schedule it sets for your site, in addition to the program's own inspection at least once every five years (140 C2).

The five-year inspection is the minimum, not the goal (Virginia DEQ Stormwater Handbook, section 10.3.4.2). Yearly inspections catch small problems early, such as a clogged outlet or built-up sediment. That keeps the property in compliance and helps avoid large repair bills nobody budgeted for.

Local rules can also be stricter than the state's. Under the federal Clean Water Act, the state requires many cities and counties to run a municipal separate storm sewer system (MS4) program to keep polluted runoff out of local waters. These local MS4 programs often set stricter rules than the state. In Arlington County, for example, commercial properties, multifamily buildings and homeowner associations must submit inspection reports every year.

Can the owner do the BMP inspection?

Not by default. The five-year inspection is done by your local stormwater program or its designee, "not to include the owner, except as provided in subsections D and E of this section" (9VAC25-875-140 C2).

Subsection D is the main exception. Your local stormwater program "may utilize the inspection reports of the owner" as part of its inspection program, if the inspection is conducted by one of these:

a person "licensed as a professional engineer, architect, landscape architect, or land surveyor"
"a person who works under the direction and oversight of" one of those licensed professionals
"a person who holds an appropriate certificate of competence" issued by the state (140 D)

Note the word "may." Subsection D allows a local program to rely on an owner's report. It doesn't require the program to accept it, and it doesn't stop the program from inspecting on its own.

Subsection E covers a narrower case, described in the next section.

Single-lot residential facilities: a different path

Some small facilities treat runoff "primarily from an individual residential lot on which such facilities are located." For these, your local stormwater program has discretion. It may decide a recorded instrument isn't needed, "provided it is demonstrated" to the program's satisfaction "that future maintenance of such facilities will be addressed through an enforceable mechanism" (9VAC25-875-130 C).

Where no recorded instrument is required, the local program must "develop a strategy for addressing maintenance" of those single-lot facilities. That strategy "may include periodic inspections, homeowner outreach and education, or other method," and "such facilities shall not be subject to the requirement for an inspection to be conducted by" the local program (140 E).

This exception covers facilities on an individual residential lot. A pond or underground system serving a subdivision, a shopping center or a business park generally falls under the recorded instrument and the five-year inspection rule above.

What this means for owners

Find your recorded instrument. It sets who is responsible, the access the property must allow, and the inspections, maintenance and reports you are expected to provide for (130 B, B3, B4). If it isn't in your files, it was recorded "in the local land records" (130 B).
Plan for an inspection at least every five years, and expect it to compare the facility against its design (140 C, C2).
Expect access to be required. The instrument must provide "all necessary access to the property for purposes of maintenance and regulatory inspections" (130 B3), so keep gates, keys and routes to the facility workable.
If you want your own report counted, have the inspection done by someone who fits 140 D, and keep in mind that your local stormwater program "may" use it. It doesn't have to.
Buying or selling property? The maintenance requirements are "stated to run with the land" (130 B2), so the duty moves with the property. Review the instrument during due diligence.
Keep your own records. Your recorded instrument must provide for "the submission of inspection and maintenance reports" (130 B4). Keeping dated copies of what you submit means you can produce them when asked.

Frequently asked questions

How often are stormwater facilities inspected in Virginia?

At least once every five years under the local stormwater program's inspection program (9VAC25-875-140 C2). Your recorded maintenance instrument may provide for inspections and reports on its own schedule (130 B4).

Who is responsible for maintaining a retention pond in Virginia?

Whoever the recorded instrument for the property names. The regulation requires long-term responsibility to be "set forth in an instrument recorded in the local land records" (130 B).

Does the maintenance obligation transfer when a property is sold?

Yes. The recorded instrument must "be stated to run with the land" (130 B2).

Can a property owner inspect their own stormwater facility?

The five-year inspection is done by the local program or its designee, "not to include the owner, except as provided in subsections D and E" (140 C2). Under D, the local program may use an owner's report when a licensed professional engineer, architect, landscape architect or land surveyor, someone working under their direction, or a holder of an appropriate state certificate of competence does the inspection (140 D).

Do I have to send inspection reports to anyone?

Your recorded instrument must provide for "the submission of inspection and maintenance reports" to your local stormwater program (130 B4). Check the instrument for what to send and when.

Do stormwater facilities on a single residential lot follow the same rules?

Not necessarily. For facilities treating runoff "primarily from an individual residential lot," the local program may waive the recorded instrument if future maintenance is addressed through another enforceable mechanism (130 C). If the program waives the recorded instrument, those facilities aren't subject to the program's inspection requirement and are handled through the program's single-lot strategy instead (140 E).

What standard is a facility inspected against?

Whether it is "being adequately maintained as designed" (140 C).
