What does the District of Columbia climate require?

Humid subtropical summers call for ACI 305 hot-weather practice, and winters cycle above and below freezing repeatedly while sidewalks, steps and bridges get heavy deicing salt.

Under ACI 318, District of Columbia falls in exposure classes F3, C2, S0. Air entrainment is required for exterior flatwork. Air entrainment is required for classes F1, F2 and F3.

How deep is the frost line in District of Columbia?

Compiled reference tables put District of Columbia at about 4 inches. That figure is orientation only. The footing depth you actually have to build to is determined by your local building department — IRC R403.1.4 requires footings to extend below the locally determined frost line, and there is no national number.

Soil concerns

Coastal plain sand and clay sit east of the Fall Line with harder Piedmont rock to the northwest, and reclaimed ground and historic fill near the waterfront need geotechnical review before slab work.

Seismic

Low seismic demand, though the 2011 Mineral, Virginia earthquake damaged masonry landmarks here. Standard detailing applies to flatwork.
