Land Surveying questions, answered by experts

You can’t build on undeveloped land without preparing it for construction, which involves running utilities to the site or accounting for private utilities like wells and septic systems and grading and compacting the soil for safe construction. Once you prepare the land, you can build on it as long as the project abides by local zoning regulations.

Professionals who complete perc tests can usually do them in a single day. Including excavating to expose the test site, filling the hole with water, and monitoring it while it drains, you can expect the test to take between four and eight hours total. It’s possible that you’ll get the results the same day, but some companies may take a few days to get official results.

Costs vary, but you can expect to spend between $1,000 and $4,000 to prepare land for a mobile home or before you build a house. You’ll need to clear enough land for the foundation, which may require leveling or grading, as well as removing trees, stumps, and plants. Don’t forget to plan for permits and fees and the installation of a gas line, water line, and sewer main.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.

Before property transactions or major improvements to ensure accuracy.
