Where the Northwest and Northeast branches meet
The town's own Port Towns page places Bladensburg at the junction of the Northwest and Northeast branches of the Anacostia River. A University of Maryland exhibit on the river says flooding has been a major part of the town's history since colonial times. For a homeowner this is practical: search your address at msc.fema.gov, the FEMA Map Service Center, and read the effective map panel.
Prince George's County's flood-reduction program lists a Northeast Branch project area at Bladensburg, ranked priority 3 and protecting 58 structures. That is a priority list and not a map of flooded streets, so it points to exposure and not to a particular block.
Four flood signals on record, and what each means indoors
| What the record says | Source type | Meaning for your property |
|---|---|---|
| The town sits where two Anacostia branches join | Town website | River water that enters a building is treated as grossly contaminated, so extraction is followed by removal of porous materials. |
| A county project area at Bladensburg protects 58 structures | County flood program | Nearby buildings have been counted as flood-exposed. Standard homeowners policies almost never cover flood, so ask about it separately. |
| A downpour in September 2020 raised water at the Old Port | Anacostia Watershed Society, a nonprofit | Short, hard storms can put water on low ground near the river without any river crest. |
| Much of the town was built before modern stormwater and floodplain rules | EPA case study on Bladensburg | Expect runoff to collect where pavement is heavy, and keep drains and window wells clear. |
None of these entries is a promise that your address will or will not flood. They are reasons to know your shutoff, your drain and your insurance before the storm.
When the river or a downpour puts water in your Bladensburg home
Move fast, but stay safe. Floodwater falls into the grossly contaminated category in the S500 water classes, so keep out of it, stay away from outlets and call (301) 936-0619, where dispatch answers all night. If you smell gas, leave the building and call 911 and the gas company from outside.
Crews start with extraction, then moisture mapping with meters and a thermal imaging camera. In a shared building, tell the property manager and the neighbors below you, because water travels along pipes, walls and ceilings.
Right now, before anything else
Shut off what feeds the water
Close the fixture shutoff or the main valve. If the source is a storm there is nothing to close, so move to the next step.
Cut power with caution
Turn off breakers for wet areas from a dry spot, and never touch a panel or cord while standing in water. A wet panel is a job for your electric utility or 911.
Raise what you can
Set furniture on blocks and carry files, chargers and small electronics upstairs. In a ground-floor unit, start with electronics and bedding.
Stay out of the water
Federal health guidance warns that floodwater can carry bacteria from overflowing sewage. Keep children and pets away and call (301) 936-0619.

Streets, landmarks and the one ZIP: 20710
Bladensburg has a single ZIP, 20710, which is also the code on Town Hall at 4229 Edmonston Road. Dispatch covers it around the clock from Hyattsville, about 1.4 miles away in a straight line.
Landmarks help a dispatcher place you. Waterfront Park at 4601 Annapolis Road is on the Anacostia, so tell the dispatcher if you are on that side of town. The Peace Cross at 4603 Bladensburg Road and Old Port Park at 4430 Baltimore Avenue also work as quick reference points.
The closest towns we also cover are Brentwood and Riverdale Park, each within roughly two miles of Bladensburg's center point.
Apartment living in a town where 82.7 percent rent
Census data republished by the Maryland Department of Planning show 82.7 percent of Bladensburg's occupied homes are rented, and 41.8 percent are in buildings of 20 or more units. In big buildings one leak often touches several households.
Bostwick, built in 1746 at 3901 48th Street, shows how old the port is. The town was chartered in 1742 and incorporated in 1854, yet only 11.3 percent of today's homes predate 1950, and 28.7 percent were built in the 1960s and 26.6 percent in the 1970s.
If you rent in a multi-unit building
- Photograph wet ceilings, floors and belongings before anything is moved, and write down the time.
- Tell the property manager in writing and ask which unit the water started in.
- Ask your insurer what your renters policy covers. It covers your belongings, not the building.
- Ask about shutoff valves and drain stacks in a building from the 1960s or 1970s, since those are the decades most of the stock comes from.
- Do not leave wet drywall alone for days. The EPA advises drying water-damaged areas within 24 to 48 hours to prevent mold growth.
Services in the order Bladensburg usually needs them
- 1
Flood damage restoration
River or storm intrusion calls for flood damage restoration: extraction, removal of materials that touched contaminated water, and drying to ANSI/IICRC S500.
- 2
Emergency water removal
Emergency water removal pulls standing water out of a lower level with extraction units before it wicks into walls.
- 3
Structural drying
Water mitigation places air movers and LGR dehumidifiers and tracks moisture meter readings until framing and drywall are dry.
- 4
Cleanup of what remains
Water damage cleanup removes wet drywall, carpet pad and ruined contents and sanitizes hard surfaces.
Town permits, utilities and mold questions
Who to ask before you rebuild
Town Code Enforcement issues building, sign and general permits, so call Town Hall before rebuilding walls, wiring or plumbing. Ask the town or Prince George's DPIE where county sign-off is needed.
WSSC Water serves Prince George's County, and its 24-hour line, 301-206-4002, takes sewer backups and main breaks. Ask the town to confirm WSSC serves your address.
Mold needs moisture, so fixing the water source comes first. Remediation and testing follow ANSI/IICRC S520, and health questions belong to a physician.
Frequently asked questions
Yes. Bladensburg has one ZIP, 20710, and it takes in Town Hall on Edmonston Road, Waterfront Park on Annapolis Road and the Peace Cross on Bladensburg Road. The 20781 code belongs to Hyattsville. If your mail shows a different ZIP, say so when you call and the dispatcher will confirm the address.
Yes. The line takes calls at any hour, including nights, weekends and storm days, and the dispatcher tells you whether same-day response is possible. Expect questions about what the water touched and where it started, followed by the plan and cost.
The nonprofit Anacostia Watershed Society wrote that a localized downpour in September 2020 pushed water levels higher at the Old Port, with debris cleared the next day. That points to rain on top of a river-side site. It is one account from a nonprofit, not a government record.
The Maryland Insurance Administration says most homeowners policies do not cover flooding. Separate flood coverage through the National Flood Insurance Program generally has a 30-day waiting period, so it must be in place before the storm. Check your policy or ask your insurer.
Tell the property manager first, because who pays turns on where the blockage is. WSSC says owners maintain the pipe between the property line and the house, and WSSC clears its own main. For the water already inside, call (301) 936-0619 and keep everyone out of it.
