Frost depth data shown in this map is queried from the North Central River Forecast Center (NCRFC) database late morning each day. Frost depth reports here are commonly from frost tube instruments, visual reports from construction or cemetery sites, or other types of electronic probes.
The frost line is simply the deepest point in the ground to which ground water will freeze. It’s also referred to as the frost depth.. When water changes from liquid to solid, it expands 9% in volume.. This resulted frost heave can be detrimental to footings and foundations.
What Is the Frost Line Depth? The frost line depth varies by geographical location, but frost lines in the contiguous United States range from 6 inches to 6 feet. Local government building officials can provide the frost line depth in a specific location.
Aptos, CA, United States. What service or documentation resource can I use to determine what the frost-line is for my area? I'd be inclined to ask the county building/planning office but I suspect that they'll want to charge for answering a seemingly simple (and hopefully well documented) question.
The frost line—also known as frost depth or freezing depth—is most commonly the depth to which the groundwater in soil is expected to freeze. The frost depth depends on the climatic conditions of an area, the heat transfer properties of the soil and adjacent materials, and on nearby heat sources. For example, snow cover and asphalt insulate the ground and homes can heat the ground (see ...
In this article, we will cover the Frost Line Depth in North America. Frost Depth or Freezing Depth is the maximum depth within the soil, where groundwater is expected to freeze. The frost depth depends on outside temperature, the amount of insulating snow cover, the heat transfer properties of the ground material near the area in question, and any possible Continue Reading
Most winters in Seattle the ground does not freeze. Last winter we only had a dusting of snow. In 30 year only remember on year in which it stayed at 18 degrees for ten days. For building purposes for those few years when it does stay below freezi...
The frost line in upstate New York is greater than 48 inches in most areas and ranges from 32 to 48 inches in other parts of the Empire State, according to Adirondack Almanack writer Tom Kalinowski. The frost line is the maximum distance below ground that soil water freezes.
Frost Line Map for Deck Footing Depth When you excavate your footings you will need to dig below the frost line. This is the depth at which the moisture present in the soil is expected to freeze.
