Landscaping, Drainage & Hardscape in Fairmount Heights, MD

Sloped Heights Terrain and the Hillside-Basement Drainage Problem

Fairmount Heights earns its name honestly: the terrain in and around the town is sloped, and the earliest and most prominent dwellings were built on the highest points of land in the original 1900 subdivision southwest of Addison Road. That slope is not a scenic footnote — it shaped how the houses were built. Because of the grade, many of the town's older dwellings feature partially exposed basements, some subterranean on one side of the house and entirely exposed on the opposite side, cut directly into the hillside. A basement like that is a drainage system whether or not anyone designed it as one: water moving downhill collects against the buried wall, and where the grade turns the corner the exposed face invites it back in. On sloped lots like these, French drain systems and yard drainage corrections are the common interventions — routing subsurface flow and surface runoff away from a foundation that sits half in the hill, before it finds the exposed wall or the basement floor. Retaining walls sized for the lateral pressure that saturated uphill soil can generate hold the grade where a hillside lot needs to be terraced or a driveway cut into the slope, and grading work re-establishes the pitch that a century of settling and successive landscaping has flattened out. Confirm the specific requirements for a retaining wall or grading project with Prince George's County DPIE before work begins.

A Branch of Beaver Creek and the Low Ground "Down in the Bottom"

The same tiny town holds the opposite drainage problem a few hundred feet away. A branch of Beaver Creek and other small streams run through the historic district, and the low-lying Sylvan Vista section, platted in 1923 on the northeast side, sat on ground low enough that it tended to be wet and swampy — residents of Fairmount Heights once referred to living there as being "down in the bottom." Within one quarter-square-mile municipality, then, there are dry hilltops shedding water and soggy bottomland collecting it, drained by small non-tidal upland streams rather than any tidal water. (This branch of Beaver Creek, the local Beaver Dam Branch named in the town's historic record, is not the same as the county's Lower Beaverdam Creek, and the sloped town has no tidal frontage — so no Chesapeake Bay Critical Area review attaches to a Fairmount Heights parcel.) The town lies within the Anacostia River watershed of western Prince George's County, so runoff leaving a low-side lot travels the small-stream network toward the Anacostia, on to the Potomac, and into the Chesapeake Bay. On the low side of town, yard drainage and French drains address standing water and a high water table where the ground itself sits in the bottom; installing an approved practice can also help reduce a homeowner's annual Clean Water Act Fee.

Permits in Fairmount Heights: a Town Code Layer Over County DPIE

Fairmount Heights is an incorporated town with a mayor-council government and its own Code of Ordinances, all within roughly a quarter square mile. That incorporation adds a town code layer: the Town's own code requires a permit before erecting or repairing a building in the Town, and the Town office sits at 6100 Jost Street. What it does not do is replace the county. Building and construction permits for a drainage system, retaining wall, patio, or grading job still run through Prince George's County DPIE — DPIE is the office a homeowner actually deals with for the construction permit, with the Town's code requirement sitting alongside it. Applications can also be filed through the county's online permitting portal. For a wall, patio, or grading job, plan on the county permit, and confirm with the Town whether its building-permit step applies to the project at hand: Department of Permitting, Inspections and Enforcement (DPIE) · 9400 Peppercorn Place, First Floor, Largo, MD 20774 · (301) 636-2050 · Monday, Tuesday, Thursday, and Friday 8:30 a.m. to 3 p.m.; Wednesday 9 a.m. to 3 p.m. Fairmount Heights properties are eligible for Prince George's County's Rain Check Rebate, administered by the Chesapeake Bay Trust — up to a $6,000 lifetime maximum per residential property for qualifying stormwater practices. See the Prince George's County page for current rates and eligibility.

Patios, Walls, Drainage, and Landscaping on Fairmount Heights' Older Lots

Patio construction, driveway installation, stone walkways, and outdoor living spaces are the big-ticket hardscape builds Actaeon takes on across Fairmount Heights' older residential lots, in concrete, natural stone, pavers, and block, with retaining walls, landscaping, sod installation, and concrete and masonry work filling out the residential scope. On the town's early-twentieth-century housing stock — much of it built between 1900 and 1960 on deep, narrow lots — a patio, driveway, or wall added to a sloped parcel changes how the lot sheds water long before it changes how the yard looks.

Fairmount Heights is one of many Prince George's County communities Actaeon serves; see the Prince George's County hub for full county coverage.

On a Fairmount Heights hillside where the basement sits buried on one side and open to the air on the other, a retaining wall and a paver terrace have to hold the grade and route its water at once — the only way hardscape lasts on ground this steep.
