Site Evaluations
A Site Evaluation means evaluating soil and site conditions for the purpose of locating areas suitable for individual sewage disposal systems as well as building and well locations for septic system design and subdivision applications. This is usually recommended if purchasing a piece of property to determine if it is a “building lot”.
Site Assessments
Please refer to NHDES Fact Sheet Transfers of Waterfront Properties with Individual Sewage Disposal Systems in the Protected Shoreland.
Plot Plans
Plot Plans may be required by the local governing body or municipality prior to going before the Planning Board, Board of Adjustment, and/or Conservation Commission.
Soil Analysis
Test Pits are dug to at least 4’ to determine soil characteristics and profile description to include Color notations based on the Munsell Soil Color Charts, Soil Structure, Soil Texture, Soil Consistency, Redoximorphic Features, and depth range for each soil horizon. Test Pits are required for Subdivisions and Individual Sewage Disposal Systems.
Wetland Delineation
Wetlands are defined in RSA 482-A:2, X, namely an area that is inundated or saturated by surface water or ground water at a frequency and duration sufficient to support, and that under normal conditions does support, a prevalence of vegetation typically adapted for life in saturated soil conditions.
A wetland delineation is required for subdivisions and most plot plans.
Septic Design
A Septic Design consists of a Site Evaluation, measuring using survey equipment to map out the topography and site conditions, deed research for the most environmental and economical approach. We can design a variety of systems to include but not limited to Stone and Pipe, Trench, Chambers, Enviro-Septic, Advanced Enviro-Septic, Eljen, and Wastewater Alternatives (Clean Solution – ATU Aerobic Treatment System). We also design serial, parallel, and sloping systems to best fit the characteristics of your property.
A Septic Design is not required for replacing a septic tank per Env-Wq 1010.14 (NHDES Subsurface Rule), replacing a pump or distribution box, or adding or replacing a vent, when no work is done on the effluent disposal area.
Subdivisions
Subdivision rules are to assure to the greatest extent possible that each lot in a subdivision or the property which a condominium is proposed can sustain on-site sewage disposal indefinitely for smart growth.
A subdivision is almost always required for local approval (town/municipality) and required for State approval if the lots are less than 5 acres or within the Protected Shoreland for water bodies located on the “Consolidated List of Water Bodies subject to the Shoreland Water Quality Protection Act”.
Shoreland Permits
A Shoreland Permit is required when new construction or construction that modifies the footprint of an existing impervious surfaces, using mechanized equipment to either excavate, remove or form a cavity within the ground and filling any areas with rock, soil, gravel or sand within 250’ landward (horizontal surveyors line) from the reference line of protected water bodies. All lakes, ponds and impoundments greater than 10 acres, all 4th order and greater streams and rivers, all designated rivers and river segments under RSA 483 (The Rivers Management & Protection Act) and all waters subject to the ebb and flow of the tide (including tidal marshes, rivers and estuaries). All water bodies protected under the Shoreland Water Quality Protection Act are located on the “Consolidated List of Water Bodies subject to the Shoreland Water Quality Protection Act”.
A Shoreland Permit consists of measuring using survey equipment to map out the topography and site conditions, deed research, a pre construction plan, post construction plan and necessary paperwork for the submission.
