Announcements

For SOIL TESTING to determine an area's suitability for a subsurface wastewater disposal system, AMY JONES, LSE, CSS, can provide both preliminary and final designs to comply with the Department of Health and Human Services, Division of Environmental Health codes.


Very poorly drained soils (left image) and poorly drained soils (middle image) define the HYDRIC SOIL classification. HYDRIC SOILS generally indicate land areas defined as WETLANDS (right image) and unsuitable for development. High intensity mapping of HYDRIC SOILS is a key component of land use planning for cluster and conservation land development projects.


We provide wetland delineation, vernal pool identification, and soil survey services for projects in both MDEP and LUPC jurisdictions. Associated permit applications are prepared following regulatory agency, town, or city statutes and land use ordinances.


Hydrologic Soil Group (HSG) is determined for each soil map unit by excavator-dug soil pits. Factors determining HSG are 1) depth to water impermeable layer, 2) depth to seasonal high water table (SHWT), 3) the least transmissive layer above the water impermeable layer, and, 4) the saturated hydraulic conductivity of the identified least transmissive layer


Our office is located in center of Portland.

Projects have ranged from a homeowner requesting a Tier I permit application to large commercial projects. A client list is available upon request.
