Y (Yes) Land Use and related structures compatible without restrictions.
N (No) Land Use and related structures are not compatible and should be prohibited.
NLR Noise Level Reduction (outdoor-to-indoor) to be achieved through incorporation
of noise attenuation into the design and construction of the structure.
25, 30, 35 Land Use and related structures generally compatible; measures to achieve NLR
of 25, 30, or 35 dB must be incorporated into design and construction of structure.
N OTES
1 Where the community determines that residential or school uses must be allowed, measures to
achieve outdoor-to-indoor Noise Level Reduction (NLR) of at least 25 dB and 30 dB, respectively,
should be incorporated into building codes and be considered in individual approvals. Normal
residential construction can be expected to provide an NLR of 20 dB; thus, the reduction
requirements are often stated as 5, 10, or 15 dB over standard construction and normally assume
mechanical ventilation and closed windows year round. However, the use of NLR criteria will not
eliminate outdoor noise problems.
2 Measures to achieve NLR of 25 dB must be incorporated into the design and construction of
portions of these buildings where the public is received, office areas, noise-sensitive areas, or
where the normal noise level is low.
3 Measures to achieve NLR of 30 dB must be incorporated into the design and construction of
portions of these buildings where the public is received, office areas, noise-sensitive areas, or
where the normal noise level is low.
4 Measures to achieve NLR of 35 dB must be incorporated into the design and construction of
portions of these buildings where the public is received, office areas, noise-sensitive areas, or
where the normal noise level is low.
5 Land use compatible provided special sound reinforcement systems are installed.
6 Residential buildings require an NLR of 25.
7 Residential buildings require an NLR of 30.
8 Residential buildings not permitted.
