Conventional construction, but with closed windows and fresh air supply systems or air conditioning, will normally suffice. 3 Normally Unacceptable: New construction or development should be discouraged. If new construction of development does proceed, a detailed analysis of the noise reduction requirements must be made and needed noise-insulation features must be included in the design. 4 Clearly Unacceptable: New construction or development should generally not be undertaken. Local Although the Project would be located in San Joaquin County, there are also nearby noise-sensitive receptors in the City of Tracy. The applicable noise standards of both jurisdictions are provided below. San Joaquin County San Joaquin County General Plan Part 3.3, Public Health and Safety, of the San Joaquin County General Plan includes a noise section that addresses noise goals and policies. Table PHS-1, Non-Transportation Noise Level Performance Standards for Noise-Sensitive Uses at Outdoor Activity Areas, lists a daytime (7 a.m. to 10 p.m.) standard of 50 dBA Leq 1-hour and 70 dBA Lmax, and a nighttime standard of 45 dBA Leq 1-hour and 65 dBA Lmax. Noise from transportation sources is addressed in Table PHS-2, which lists a maximum allowable noise standard of 65 dBA Ldn for outdoor residential uses and 45 dBA Ldn for interior residential spaces. These standards are applicable to new or existing residential areas affected by new or existing sources. Additionally, Goal PHS-9.4, Acceptable Vibration Levels, requires that construction projects anticipated to generate a significant amount of vibration ensure acceptable interior vibration levels at nearby vibration-sensitive uses based on FTA criteria (County of San Joaquin 2016). San Joaquin County Municipal Code Title 9, Chapter 9-1025.9 of the County of San Joaquin (County) Municipal Code has noise performance standards for various land use types that are consistent with the County’s General Plan. The Municipal Code also specifies exemptions to the various standards, including for noise from construction activities, provided that such activities do not take place before 6 a.m. or after 9 p.m. on any day.
