Extracted standards
5 individual requirements pulled out of this section’s prose, each with the sentence it came from.
Floodplain
- Anchoring
New construction and substantial improvements shall be according to the VA USBC, and anchored to prevent flotation, collapse or lateral movement of the structure.

The bottom of all required openings shall be no higher than one foot above the adjacent grade.
- Floodproofing for non-residential
New construction or substantial improvement of any commercial, industrial, or non-residential building... may be flood-proofed in lieu of being elevated provided that all areas of the building components below the elevation corresponding to the BFE plus one foot are water tight...
- Lowest floor elevation
New construction or substantial improvement of any residential structure... shall have the lowest floor, including basement, elevated to or above the base flood level.
- No encroachment without analysis
No encroachments, including fill, new construction, substantial improvements or other development, shall be permitted unless it has been demonstrated through hydrologic and hydraulic analyses... that the proposed encroachment would not result in any increase in the 100-year flood elevation.
