Drainage Solutions for Washington Homes
Drainage trouble in the District usually starts with the lot, not the weather alone. Rowhouse yards on Capitol Hill, in Eckington and in Petworth are boxed in by walls and paving, with English basement areaways that collect water at the lowest point. Detached homes in Woodridge, Brookland and Cleveland Park often sit on slopes where runoff from the street or a neighbor crosses the yard. Compacted fill, downspouts dumping at the foundation and paving pitched the wrong way are the most common causes.
Fixes match the problem. French drains collect groundwater and surface runoff in a gravel trench with perforated pipe and carry it to a safe outlet. Regrading pitches soil away from the house. Downspout extensions or buried lines move roof water away from basement walls, sometimes into a dry well or rain garden. Permeable pavers and rain gardens let water soak in on site, and some of this work may qualify for DOEE RiverSmart help or stormwater fee discounts, so check current rules.
Soil varies across the city. Northwest lots near Rock Creek have silty, rocky ground, while the east side has sand, gravel and clay layers that can drain slowly. Many older neighborhoods are on a combined sewer system, so keeping roof water on site helps. Trenching waits until utilities are marked through 811. Call to have a pro walk your yard during or after a storm.

Washington Notes
English basement areaways in rowhouses collect water fast, so their drains need to be clear and well connected. Shared walls and alleys mean water from one yard can affect the next. Summer thunderstorms and remnant tropical storms drop heavy rain fast across DC. Compacted fill and paved yards leave water nowhere to go.
Typical Timeline
Downspout lines often take a day. French drains and regrading on a city lot usually take two to five days.

Drainage Solutions FAQs
Why does water pool in my rowhouse yard?
Walls, paving and compacted fill trap water with no place to go, so it needs a drain or regrading.
Will a French drain fix a wet basement?
It helps when water comes from the yard. Downspouts and grading often need attention too.
Where can drained water go?
To a dry well, a rain garden, a lower part of the yard or another suitable outlet, depending on the lot.
Can a rain garden help?
Yes. A rain garden near a downspout soaks up roof water on site.
When should drainage be fixed?
Soon after you notice problems, since water damage to foundations gets worse over time.
