<br />Euclid Street Zone Change/Subdivision ER 2005-138 <br /> <br />potential amount of vehicle trips that could occur along <br />Euclid Street, the proposed proj ect could be subj ect to <br />vehicle noise impacts that could potentially exceed the <br />City's interior noise standards. Because the exterior <br />Ii ving areas would be shield by the proposed homes, it <br />would be expected that the proposed project would meet the <br />City's exterior living noise standard. <br /> <br />To insure the proposed <br />interior noise standard, <br />shall be implemented. <br /> <br />proj ect complies with the City's <br />the following mitigation measure <br /> <br />Mitigation Measure <br /> <br />· Prior to issuance of Building Permits, the project <br />developer shall submit a Noise Study to the Planning <br />Department that identifies traffic related noise <br />levels and if needed design recommendations to insure <br />that the project complies with the City's interior <br />noise standard of 45 db CNEL. <br /> <br />C. A substantial permanent increase in ambient noise <br />levels in the project vicinity above levels existing <br />without the project. <br /> <br />Less than Significant Impact <br /> <br />The proposed project would generate a minimal amount of <br />additional traffic within the project area. No significant <br />increases in existing noise levels are expected to occur <br />from project related traffic. <br /> <br />B. Exposure of persons to or generation of excessive <br />groundborne vibration or groundborne noise levels. <br /> <br />Less Than Significant Impact <br /> <br />Vibration is a trembling, quivering, or oscillating motion <br />of the earth. Vibration can be either natural as in the <br />form of earthquakes, volcanic eruptions, sea waves, <br />landslides, etc. or man-made as from explosions, the action <br />of heavy machinery, or heavy vehicles such as trucks or <br />trains. Both natural and man-made vibration may be <br />continuous such as from operating machinery, or transient <br />as from an explosion. <br /> <br />20 <br /> <br />75A-39 <br />
