Detailed mapping of elevation changes and natural features on the property.

Soil testers and licensed excavators are often the professionals you hire if you need a perc test. In some cases, structural engineers will also be able to conduct the test for you. In many municipalities, you’ll need your professional on-site to dig and fill the holes with water, as well as a representative from your local building department or health department. That representative is the individual who will determine whether your test passes or fails.

A few different types of land surveys can help determine certain features and boundaries of your property. These include:

• Boundary surveys describe the actual borders of a property. These are generally required when trying to get construction permits issued. 

• Location surveys provide much of the same information as a boundary survey but also include in-depth information about any improvements made to your property. 

• Mortgage location surveys are usually required by lenders and title companies before financing or offering an insurance policy. 

• Site-planning surveys are done before applying for building permits and can be issued before any major home improvements. 

• Topographic surveys provide a formal map of land elevations. It can also describe the location and size of natural features and any land improvements.

Building a road on a slope requires careful planning and will normally require a drainage system underneath to prevent flooding and damage to the road over time. Your professional may lengthen your road to create switchbacks if the slope directly to your home is too steep, as there are regulations for maximum road slope. The drainage system will help prevent runoff from the higher side of the slope from damaging the asphalt or concrete. Keep in mind that building a road on a slope isn’t a good DIY project, as a lot can go wrong.
