Tewksbury Township ordinances require that all swimming pools be set back a minimum of 10 feet from both side and rear property lines. Additionally, the pool must be located behind the rearmost point of the dwelling and at least 10 feet away from any other building on the lot, such as a garage or cabana.
yes, typically. Improvements to legally existing single-family dwellings (in existence since August 10, 2004), including swimming pools and patios, are generally covered under Exemption #4 of the Highlands Act. We assist with the “Highlands Exemption” application to ensure your project stays compliant with NJDEP regulations.
In Tewksbury, the creation of new impervious surfaces (pool + patio) exceeding 1,000 square feet triggers a requirement for a stormwater management plan. We design custom drainage solutions, such as dry wells or seepage pits, to handle runoff and meet township engineering standards.
Tewksbury is known for its dense red shale and rocky geology. Our excavation teams use specialized heavy-duty machinery to break through this hard ground efficiently. We also engineer the pool sub-base to account for these specific soil conditions, preventing future settling or structural issues.
Since many Tewksbury homes rely on septic systems, we must ensure the pool is placed a safe distance from your tank and disposal field (typically 20 feet). We coordinate with the Hunterdon County Board of Health to verify your plot plan doesn’t interfere with your wastewater infrastructure.
If your construction project disturbs more than 5,000 square feet of land, you must obtain certification from the Hunterdon County Soil Conservation District. We manage this entire process, including the submission of an Erosion and Sediment Control plan, to keep your project moving legally.
