Mountain Conservation District
The purpose of the Mountain Conservation District is to preserve and protect the fragile ecosystem and preserve the rural character of the Sourland Mountain. The district is designed to prevent the overuse of limited water resources and respect the ability of the soils and ground water to sustain on-lot disposal systems without degrading or impairing surface or ground water quality. Rugged terrain, rocky soils, extensive wetlands and mature forests typify this environment, which is poorly suited to accommodate residential or other development that will require reliable water supplies. Due to these natural limitations, it is important to limit impervious cover in order to foster maximum recharge and sustainable yields in the district and regional watersheds dependent on the limited groundwater supply. The Mountain Conservation District is also designed to preserve biological diversity and environmental integrity through the maintenance of large contiguous tracts of forest.
