(24) Where warranted, an acoustical evaluation demonstrating future compliance with the regulations established by both the New Jersey Department of Environmental Protection (NJDEP) (N.J.A.C. 7:29 Noise Control) as may be amended and supplemented and the Township of West Windsor (Administrative Code Chapter
113) as may be amended and supplemented shall be completed and submitted by the applicant. At a minimum, such an evaluation shall identify the sources of expected sound to be generated by the proposed development to ensure that there will be no adverse impacts as related to noise. Those locations with a greater potential for exceedances shall provide anticipated noise levels generated by the proposed development. An acoustical analysis to estimate the anticipated sound levels shall be required and appropriate abatement/mitigation be designed, if necessary.
If requested by the Township of West Windsor, an acoustical evaluation shall be completed and submitted by the applicant that demonstrates the potential impacts of noise on the proposed development from surrounding sources. Those locations with a greater potential for impacts shall provide the anticipated noise levels of the sources of sound expected to impact the proposed development.
