The governing body of East Brunswick Township finds that riparian lands adjacent to streams, lakes, or other surface water bodies that are adequately vegetated provide an important environmental protection and water resource management benefit. It is necessary to protect and maintain the beneficial character of riparian areas by implementing specifications for the establishment, protection, and maintenance of vegetation along the surface water bodies within East Brunswick Township. consistent with the interest of landowners in making reasonable economic use of parcels of land that include such designated areas.
The specific purposes and intent of this Ordinance are to:
A. Restore and maintain the chemical, physical, and biological integrity of the Township's water resources;
B. Prevent excessive nutrients, sediment, and organic matter, as well as biocides and other pollutants, from reaching surface waters by optimizing opportunities for filtration, deposition, absorption, adsorption, plant uptake, biodegradation. and denitrification, which occur when stormwater runoff is conveyed through vegetated buffers as stable, distributed flow prior to reaching receiving waters;
C. Provide for shading of the aquatic environment so as to moderate temperatures, retain more dissolved oxygen, and support a healthy assemblage of aquatic flora and fauna:
D. Provide for the availability of natural organic matter (leaves and twigs) and lame woody debris (trees and limbs) that provide food and habitat for aquatic organisms (insects, amphibians, crustaceans, and small fish). which are essential to maintain the food chain;
E. Increase stream bank stability and maintain natural fluvial geomorphology of the stream system, thereby reducing stream bank erosion and sedimentation and protecting habitat for aquatic organisms;
F. Maintain base flows in streams and moisture in wetlands;
G. Control downstream flooding: and
H. Conserve the natural features important to land and water resources, e.g., headwater areas, ground water recharge zones, floodways, floodplains, springs, streams, wetlands. woodlands. and prime wildlife habitats
East Brunswick Township is empowered to regulate land uses under the provisions of the New Jersey Municipal Land Use Law, N.J.S.A 40:55D-1 et seq., which authorizes each municipality to Ian and re. ulate land use in order to rotect ublic health safe and welfare b rotectin and maintaining native vegetation in riparian areas. The Township is also empowered to adopt and implement this Ordinance under provisions provided by the following legislative authorities of the State of New Jersey:
