Frost line depth
Frost line depth
(OP)
Hello All,
How can I determine the frost line depth for a project in Virginia? All I can find in the code is in R301.2 which leaves in up to the locality. The online version of the code is blank in this section. Any help would be appreciated.

These typically show maximum frost depth in the ground and are not associated with buildings and building foundations.
The presence of a building affects the frost depth as there is some level of insulating/heating that occurs at the footing.
All that to say - do what birneys suggests...

Altitude will have an effect.
The county soil surveys by USDA may have information
Like OG, I would check with local building inspectors, house builders, etc for local practice.
