Landscaping, Drainage & Hardscaping in Anne Arundel County, Maryland

Drainage and Stormwater Services in Anne Arundel County

Most of Anne Arundel County's borders are defined by water. To the east lies the western shore of the Chesapeake Bay, and tidal tributaries indent the shoreline throughout the county. That geography shapes two distinct residential drainage contexts. Upland communities — Crofton, Odenton, and the inland residential areas — sit on the same clay-heavy Piedmont soils that drive drainage problems across the DC-Maryland region: low-permeability material that sheds water along the surface rather than absorbing it, producing saturated turf, pooling yards, and water at foundation walls after any significant storm. Near-Bay and waterfront properties carry additional considerations under the Chesapeake Bay Critical Area, which adds review requirements and restrictions to disturbance within 1,000 feet of tidal waters.

Actaeon installs French drain systems, catch basins, surface drainage inlets, and buried downspout extension runs to route water away from structures on upland properties. Where the underlying problem is a grade that no longer moves water — built up against foundations through successive landscaping projects or settled over decades — we regrade and install subsurface drainage to handle what the surface alone cannot move. For commercial and government clients, Actaeon provides BMP installation and maintenance for permitted stormwater facilities. As a Maryland Licensed Marine Contractor, we are qualified for construction and excavation work in and near tidal waters — relevant to the waterfront and near-water project scope the county regularly presents.

Retaining Walls, Patios, and Hardscaping

Anne Arundel County's permit rules for hardscape work differ from what many homeowners know from neighboring counties. Retaining walls over 24 inches in height require an Accessory Structure permit from the Department of Inspections and Permits; engineering drawings are required for walls over 4 feet. Patios and driveways, however, do not require a building permit — a Standard Grading Plan Application may be required depending on the project's size and area of disturbance, and driveways may require Right-of-Way approval from the Department of Public Works. That distinction matters: projects that require permits in Montgomery County may not require them here, and the county permit office can confirm thresholds for a specific project before design begins.

On waterfront and near-Bay lots, any hardscape work near tidal shorelines is subject to Critical Area restrictions on impervious surface coverage within the buffer zone — retaining walls, patios, or driveways within the 1,000-foot Critical Area buffer may face limits on total impervious area that affect scope. We account for those constraints before finalizing designs near tidal water. Stone installations, driveways, and concrete and masonry work are routine across the county's established residential areas regardless of Critical Area status.

Sod, Landscaping, and Bay-Watershed Plantings

Sod installation in Anne Arundel County follows the same clay-soil preparation protocol as the rest of the Maryland Piedmont: grade correction and soil amendment before sod is laid, because sod placed on compacted clay without adequate preparation cannot establish a root zone capable of surviving the first dry stretch after installation. We install sod for residential lawns, HOA common areas, and restoration projects where immediate ground cover is required for erosion control.

Landscaping and native planting work in the county benefits from Actaeon's Chesapeake Bay Landscape Professional (CBLP Level 1 and Level 2) certification, which covers native plant selection, Bay buffer management, and stormwater management in the Bay watershed. Properties within the Critical Area require particular attention to plant selection and site management during any disturbance or restoration work; CBLP certification is directly applicable to that context. Beyond the Critical Area, plants adapted to Maryland Piedmont conditions outperform ornamentals not suited to the local hydrology — an establishment advantage that carries through the county's clay-heavy upland residential areas as well as its waterfront neighborhoods.

Permits and Stormwater Credits in Anne Arundel County

Unlike neighboring counties with many incorporated municipalities — each running its own permit office — Anne Arundel County keeps it simple for most addresses. Only the City of Annapolis and the Town of Highland Beach have separate permit processes. Every other address in the county routes permits through one office:

Anne Arundel County 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

Permit thresholds: Retaining walls over 24 inches require an Accessory Structure permit. Driveways and patios do not require a building permit — a Standard Grading Plan Application may apply depending on the size and disturbed area, and driveways may require Right-of-Way approval from the Department of Public Works. Engineering drawings are required for retaining walls over 4 feet in height.

Stormwater credits — not rebates: Anne Arundel County offers two programs for property owners who install qualifying stormwater practices. The Stormwater Management Property Tax Credit reduces your annual property tax bill by 10% of qualifying installation costs, up to a total credit of $10,000 over five years — a credit against taxes owed, not a cash reimbursement. The Watershed Protection and Restoration Fee (WPRF) Credit reduces your annual WPRF fee by up to 50%. Neither program provides direct cash payment. Homeowners familiar with the Montgomery County RainScapes Rewards Rebate should note the difference: the AA programs reduce bills rather than reimburse costs. Contact the county's Bureau of Watershed Protection and Restoration at aacounty.org for current qualifying practices and application requirements.
