District of Columbia Paving & Pavement Contractors

What makes pavement work different in District of Columbia?

In Washington, D.C. the hardest part of a pavement project is usually establishing which of three regulators has jurisdiction over which part of it.

• Work in public space — sidewalks, alleys, curb cuts, and areas beyond the property line — requires a DDOT public space permit, and the public space boundary is frequently not where owners assume it is.
• DOEE administers District stormwater regulations with retention volume requirements for qualifying projects, plus a stormwater retention credit trading program with no direct equivalent in the surrounding states.
• The District is not authorized to administer the federal NPDES program, so federal construction stormwater permit coverage comes from EPA rather than from a District agency.
• The Fall Line runs through the city, so northwest properties sit on Piedmont residual soils over crystalline rock while eastern and southern properties sit on softer Coastal Plain sediments.
• Much of the low-lying core is built on historic fill, which makes settlement over buried material and utilities a normal reconstruction risk rather than an unusual one.
