The primary purpose of the City of Santa Ana <br />Noise Element is to establish noise level guidelines that are <br />compatible with different types of land uses and to prevent <br />significant increases in noise levels in the community. These <br />guidelines for exterior noise levels as presented in Table N-1. <br />Table N-1 <br />Citv Of Santa Ana Land Uae Guidelines For Exterior Noise <br />Land Use Noise Level (dBA CNEL or Ldn) <br /> Desirable <br />Maximum Maximum Acceptable <br />Low Density <br />Residential 55 65 <br />Medium Density <br />Residential 60 65 <br />High Density <br />Residential 65 70 <br />Schools 60 70 <br />Commercial, Office 65 75 <br />Industrial 70 75 <br />Existing Noise Setting <br />The project site is located within an urban environment and is <br />primarily impacted with mobile source noise impacts from First <br />Street.
