Landscaping, Drainage & Hardscape in Severn, MD

Drainage and Stormwater Services in Severn

Severn sits in northwestern Anne Arundel County, where the non-tidal, nine-mile Severn Run begins — a headwater stream that feeds the Severn River system downstream. Residential drainage and hardscape runoff across Severn moves toward Severn Run rather than any tidal shoreline, which shapes how yard-drainage and stormwater work is planned here: the goal is carrying surface water off the property without eroding toward the Run and its tributaries.

French drain and yard drainage installations address the headwater drainage conditions of the Severn Run corridor — low spots that hold water after heavy rain, saturated lawns, and downspout discharge with nowhere to go. Because Severn's waters are non-tidal, it sits outside the tidal-shoreline constraints that govern the county's waterfront communities.

Retaining Walls, Patios, and Hardscape in Severn

With 57,118 residents, Severn is a large residential community in northwestern Anne Arundel County, and its neighborhoods carry the full range of hardscape needs. Retaining walls, patios, stone installations, concrete and masonry, driveways, and outdoor living spaces are the core hardscape scope for Severn homes. Severn's housing has expanded steadily — the community grew 22.6% between 2010 and 2020 — and homes across the community reach the point where drainage grading and hardscape need attention.

Because Severn is unincorporated, hardscape permitting runs entirely through the county: retaining walls over 24 inches require an Accessory Structure permit, with engineering drawings for walls over four feet, while patios and driveways need no building permit — though a Standard Grading Plan Application may apply depending on the disturbed area.

Permits and Stormwater Credits for Severn Homeowners

Severn is unincorporated — there is no city permit office. Every permit application goes to Anne Arundel County's Department of Inspections and Permits: 2664 Riva Road, Heritage Office Complex, Annapolis, MD 21401 · (410) 222-7730 · Monday–Friday 8:00 AM–3:45 PM.

Homeowners who install qualifying stormwater practices can offset two separate county charges. The Stormwater Management Property Tax Credit returns 10% of installation cost against the annual property tax bill, up to $10,000 over five years. The Watershed Protection and Restoration Fee Credit lowers the yearly WPRF charge by up to 50%. Both reduce bills the homeowner already owes rather than paying cash. Contact the county's Bureau of Watershed Protection and Restoration at aacounty.org for current qualifying practices.
