tAmy Gartin 11 October 2011 Page 3 Noise levels shall be measured at the property line of the nearest site which is occupied by,zoned for, and/or designated on the City's General Plan Diagram to allow the development of,noise-sensitive land uses. b. Maximum Sound Level. i. Commercial. (A) The maximum sound level(Lmax)produced by commercial land uses or by other permitted noise-generating activities on any retail commercial zoning district(i.e., CO, CN, CG, CD, CL, or CA districts) shall not exceed 75 dB; and (B) The hourly equivalent sound level (L�q)from these land uses shall not exceed 65 dB during daytime or nighttime hours as measured at the property line of any other adjoining retail commercial zoning district(CO, CN, CG, CD, CL,or CA districts). TABLE 3-7 PART II-NOISE STANDARDS FOR OUTDOOR ACTIVITY AREAS Noise Level Descriptor Day(7:00 a.m.to 10:00 p.m.) Night(10:00 p.m.to 7:00 a.m.) Hourly Equivalent Sound Level(L,),dB 55 45 Maximum Sound Level(Lmax),dB 75 65 Based on the October 2011 site plan, it appears that the nearest residential receiver(along E p 9 Pp ( g Myrtle Street)will be located approximately 200-feet south of the project entrance/exit, and the nearest commercial receiver will be the convenience store located at the southwest corner of Weber Avenue and N Filbert Street. Therefore,based on our interpretation of the City's Development Code Noise Standards,the following noise levels cannot be exceeded: TABLE 2:PROJECT RECEIVER NOISE STANDARDS BASED ON CITY OF STOCKTON DEVELOPMENT CODE Daytime Nighttime Lmax Location Le.(dBA) Le (dBA) (dBA E Myrtle Street Residences 55 45 65 Convenience Store(Weber and Filbert) 65 65 75 *Daytime and Nighttime L_are the same. SECTION 2: EXISTING NOISE ENVIRONMENT To quantify the existing noise environment at the project site,we conducted five continuous 24-hour noise measurements from 12 to 13 September and 19 to 22 September 2011. The dominant noise source is local traffic on N Filbert Street and Weber Avenue. CA-4 also contributes to the noise environment but to a lesser degree.Table 3 and Figure 1 show a summary of the measured data.
