What are the results of the noise study? <br />The results of the noise study are shown on Tables 27 and 28. Information in the tables show <br />receptor locations (location for where the noise is reported as shown on Figure 22), existing <br />noise levels, future noise levels without the project (No -Build Noise Levels) and future noise <br />levels with the project (Post - Development Noise Levels). <br />For example, if you live at Receptor #1: <br />• The existing noise level is 69.7 dBA. <br />• If the roadway is not expanded, future noise levels will be 70.7 dBA in 2030 (the No- <br />Build Noise Level column), an increase of 1 dBA over the current level. <br />• If the roadway is expanded, the noise level is expected to increase to 72.0 dBA, a 2.3 <br />dBA increase over current levels. <br />• In all cases, the noise levels at Receptor #1 exceed the federal criteria for noise <br />abatement (shaded areas on the table). <br />• Because the noise at Receptor #1 exceeds the federal criteria, noise mitigation options <br />(walls or berms) must be analyzed. <br />Table 27 - CSAH 116 Reconstruction Project <br />Dnvtime - Mndeled Prnieet Tmnacts - Residential Reeentors <br />a Reeeptora,� <br />'����Existing`` � <br />,�I�Io Build <br />No $u�ld� >s <br />yxSy�� � 3 � , , t <br />Z beve <br />��`1?ost � } >` <br />< <br />`Ioise Levels <br />Noise Levels <br />Increase Over <br />Deve ol�p eu <br />t <br />Dvelopmen <br />N <br />(io dBA « <br />dBA <br />Extshn n <br />1 <br />otse evels <br />crease Over . <br />� <br />2 <br />;- <br />Noise I,eveCs � <br />u <br />pg <br />R1 <br />69.7 <br />70.7 <br />1.0 <br />72.0 <br />2.3 <br />R3 <br />69.7 <br />70.6 <br />0.9 <br />1 72.0 <br />2.3 <br />R5 <br />69.9 <br />70.7 <br />0.8 <br />72.2 <br />2.3 <br />R7 <br />70.1 <br />70.8 <br />0.7 <br />72.3 <br />2.2 <br />R9 <br />69.6 <br />70.3 <br />0.7 <br />71.6 <br />2.0 <br />R11 <br />68.0 <br />68.7 <br />0.7 <br />69J <br />1.7 <br />R13 <br />61.7 <br />62.6 <br />0.9 <br />63.2 <br />1.5 <br />R15 <br />62.0 <br />62.9 <br />0.9 <br />63.5 <br />1.5 <br />R17 <br />62.0 <br />63.1 <br />1.1 <br />63.7 <br />1.7 <br />R19 <br />62.0 <br />63.2 <br />1.2 <br />63.8 <br />1.8 <br />R21 <br />62.4 <br />63.8 <br />1.4 <br />64.3 <br />1.9 <br />R23 <br />62.7 <br />64.4 <br />1.7 <br />64.9 <br />2.2 <br />R25 <br />68.3 <br />71.4 <br />3.1 <br />72.2 <br />3.9 <br />R27 <br />68.6 <br />72.0 <br />3.4 <br />72.7 <br />3.8 <br />R29 <br />67.4 <br />70.7 <br />3.3 <br />- 71.2 <br />3.8 <br />R31 <br />61.6 <br />64.3 <br />2.7 <br />64.6 <br />3.0 <br />R33 <br />67.4 <br />70.7; <br />3.3 <br />J11 _ <br />3.8 <br />
