Zoning
MP
Mountain Preservation District
The Township of Green Brook includes a portion of the Watchung Ridge, parts of which contains slopes exceeding 20 percent grade. Such area, designated in this ordinance as the MP Mountain Preservation District, has physical conditions which preclude development, and the stripping of such woodlands, and development thereof would constitute dangers and hazards to life and public and private property and facilities, and the great increase in flooding of low-lying areas. Accordingly, if such area is to be developed at all, or changed in any manner from its existing natural wooded state, such development or changes must be strictly limited and carefully planned so as not to aggravate the serious water problems now coming from said area, and so as not to destroy the purposes served by such areas in maintaining the environment and preventing erosion, flooding, and other hazards.
