FAQ
From USDA soil survey data, the most common across the state: no hazard rates high in most counties. A parcel can differ from its county, so read the survey for your exact site.
From the Commerce Department's Regional Price Parities, on the same Richmond Metro = 1.00 scale as Virginia. Across 29 reviewed regions that method missed by about 0.03 on average. They have not been checked against executed bids in District of Columbia, so use them for planning, not a final bid.
They are screening ratings from federal soil and geology data, not a local estimator's review and not a geotechnical report. Tested against 511 reviewed counties, they land within one level most of the time, and exact matches are less common. Get borings before you price a real site.
