DISCUSS POTENTIAL <br />IMP ACTS ON HUMAN HEALTH OR QUALITY OF LIFE. <br /> <br />AUAR: <br />Dust, odors, and construction noise need not be addressed in an A UAR, unless there is <br />some unusual reason to do so. The RGU might want to discuss as part of the mitigation <br />plan, however, and dust control or construction noise ordinances in effect. <br /> <br />If the area will include or adjoin major noise sources a noise analysis is needed to <br />determine if any noise levels in excess of standards would occur, and if so, to identifY <br />appropriate mitigation measures. With respect to traffic-generated noise, the noise <br />analysis should be based on the traffic analysis of item 21. <br /> <br />Odors & Dust Durin!! Construction <br /> <br />The proposed project will not generate any odors during construction. Dust normal to <br />construction will occur as a result of this projcct. Dust generated during construction will <br />be minimized through standard dust control measures such as watering. After construction <br />is complete, dust levels are anticipated to be minimal because all soil surfaces will be in <br />permanent cover (i.e., pavement or grassed areas). <br /> <br />Construction Noise <br /> <br />Typical construction noise will be generatcd during project construction. Noise impacts <br />caused by construction activities in the project area will vary depending on the type of <br />equipment in use, the location of equipment on the construction site, and the operating mode. <br />During a typical work cycle, construction equipment may be idling, preparing to perform a <br />task, or operating under a full load. It may be congregated in a specific area or spread out <br />over a larger area. For this reason, the total noise impact on a single receiver point resulting <br />from construction of the project will vary both day-to-day and hour-to-hour. <br /> <br />The range of average noise levels monitored at 50 feet from a variety of types of construction <br />equipment is shown in Table 2 l. These types of equipment are generally associated with site <br />grading and site preparation, generally the noisiest phases of construction. <br /> <br />Guidant Campus Master Plan <br />Final AUAR and Mitigation Plan <br /> <br />- 47- <br /> <br />January 2003 <br />
