The Maryland Stormwater Management Act requires environmental site design to the maximum extent practicable on Harford County development. New construction needs an approved stormwater management plan that maintains predevelopment runoff before any grading permit issues.
Md. Code, Environment §4-201 et seq. governs stormwater across Harford County, from Bel Air and Abingdon on the piedmont to the coastal plain around Edgewood and Joppatowne. The state program's primary goal is to hold post-development runoff as close as possible to predevelopment conditions. Every development must use environmental site design (ESD), meaning small-scale practices like bioretention, rain gardens, and permeable surfaces, to the maximum extent practicable, with structural ponds allowed only where absolutely necessary. The Maryland Department of the Environment sets the standards, and Harford County reviews and approves the stormwater management plan before construction, tightening treatment for runoff draining toward the Bush and Gunpowder Rivers and the Chesapeake Bay.
Grading or building without an approved stormwater management plan violates the Stormwater Management Act and the county code, drawing stop-work orders, MDE enforcement, penalties, and orders to retrofit the drainage system.
