  • Wetlands Identification has been providing wetland consulting services in Eastern Massachusetts since 1996.

    We assist homeowners and others filing with Conservation Commissions and the Department of Environmental Protection. 

    We use vegetation, soils and other indicators to delineate and flag wetlands.  State and local regulations guide the methods we use to do this.  In most cases, we write reports for the Conservation Commission's review, describing the site and the delineation. 

    If requested, we will evaluate suitability of projects near wetlands, in terms of site hydrology, zoning requirements and wetland regulations.

    Wetlands Identification is experienced in guiding clients through the application and hearing process for an Order of Conditions (construction permit) from the Conservation Commission.  We can fully prepare applications and site plans for your submission, or assist homeowners, architects, engineers and developers as needed.

    We perform soil evaluations for septic systems and stormwater infiltration systems, providing a Professional Engineer with groundwater data necessary for design.   That data may include Estimated Seasonal High Groundwater and percolation rates. 

    In several cases we have reviewed abutting development projects for homeowners or others.

    We determine Mean High Water lines for rivers and streams,  perenniality of flow, and historic high and low tide lines.  Using remote mapping or on-the-ground surveys, we locate flood zones or Base Flood Elevations at a site.  

    In design or other stages of a project, we prepare topographic surveys showing wetland or property boundaries, with other existing or proposed features.

    Our staff is led by David A. Sperduto, a wetland delineator, botanist, wetland hydrologist, DEP-approved Soil Evaluator, and Professional Land Surveyor.  He has been working in each of these fields over 20 years or more.   He has been involved in a wide variety of projects adjacent to wetlands, streams and the ocean.  He has provided expert witness testimony in hearings and court cases involving wetlands, soils and hydrology.

    David has provided wetland delineation, soil interpretation, flood zone, and tideland services for Massachusetts homeowners and businesses in Lexington, Burlington, Billerica, Wellesley, Arlington, Hubbardston, Boston, Cambridge, Somerville, Concord, Winchester, Lynn, Groton, Belmont, Needham, Brookline, Dover, Sherbourne, and Haverhill, Massachusetts.
