In recent years, great emphasis has been placed on controlling stormwater runoff and protecting waterways from the negative effects of earthmoving and construction activities. Regulations imposed by County Conservation Districts and the Department of Environmental Protection (DEP) are constantly evolving and have created a need for specialists in these areas. Lehigh Engineering’s Environmental Department is experienced in working with these governing organizations and has the ability to provide cost-effective designs that meet their requirements.
Our firm routinely prepares Erosion & Sedimentation Control Plans and Narratives for projects of all sizes, from individual lot grading plans to large scale subdivisions and land developments. We also have the capability to design Post Construction Stormwater Management Plans and handle all related permit applications necessary to obtain approval. Some examples of these permits include General and Individual National Pollutant Discharge Elimination System (NPDES) permits, Water Obstruction & Encroachment Permits, and Wetland Permits. In addition to these functions, our office performs Phase I Environmental Site Assessments, ASTM Standard 1527-05.
As part of our subdivision and land development plan process, Lehigh Engineering completes the designs for central sewage systems and on-lot septic systems. We also prepare stormwater management plans and reports, which encompass items such as the storm piping system, detention basins, swales, diversion berms, and infiltration systems.
