would change the character of the noise generated on the <br />site and, therefore, the noise levels surrounding the site <br />as construction progresses. Despite the variety in the <br />type and size of construction equipment, similarities in <br />the dominant noise sources and patterns of operation allow <br />construction -related noise ranges to be categorized by work <br />phase. Table N-4 identifies estimated noise levels for the <br />various construction phases of the project. The nearest <br />noise sensitive uses within the project area are the <br />existing single family land uses that abut the project <br />site. <br />Table N-4 <br />Typical Noise Level at Construction Sites <br />Construction Phase <br />Minimum Required <br />Equipment in Use <br />All Applicable <br />equipment In Use <br />Excavation <br />79 <br />89 <br />Foundation <br />Construction <br />78 <br />78 <br />Building Construction <br />76 <br />85 <br />Finishing/Site <br />cleanup <br />76 <br />89 <br />Construction of the proposed project would not involve the <br />use of large quantities of construction equipment. Grading <br />for the site would be minimal because of the flat condition <br />of the project site. Using a worst case distance of 50 -feet <br />from the property lines of the nearest noise sensitive uses <br />to the center of construction activities, and not <br />accounting for the 6 foot perimeter wall around the <br />northern boundary of the project site, noise levels could <br />intermittently range from 78-89 dBA Leq at the nearest <br />noise sensitive land uses. <br />The Municipal Code Noise Ordinance recognizes that some <br />forms of noise are required for urban development and <br />maintenance and are difficult to control. Section 18-314(e) <br />exempts noise sources associated with construction, repair, <br />remodeling, or grading of any real property, provided said <br />activities take place between the hours of 7:00 a.m. to <br />8:00 p.m. Monday through Saturday with no construction <br />activity permitted Sundays or federal holidays. While <br />adverse, construction, when performed in compliance with <br />the requirements of the Municipal Code is considered to be <br />less than significant. While construction related noise <br />impacts are exempt under the Municipal Code Noise <br />27 <br />
