patterns. There are no surface waters to which drainage might be discharged into. Project drainage would go through the existing storm drain system. No groundwater would be affected by development of the project, nor is the project site within an identified flood zone. FINDING: No impacts to water resources are anticipated. 5) BIOTIC RESOURCES EFFECT: Due to the existing developed'state of the project site, no significant, rare or endangered plant or animal species currently exist. Therefore, redevelopment of the site with residential uses would not result in a potentially significant impact. FINDING: No impacts to plant or animal species are anticipated. 6) CONSTRUCTION NOISE EFFECT: A noise analysis was performed by Robert Shaw in conjunction with an application for HUD/FHA funding for the project. This report concluded that the project site has an overall day-night average noise level of 78.5 DNL, as a result of fronting on E. 14t'' Street, a major roadway. The San Leandro General Plan contains guidelines for determining the compatibility of various land uses with different noise environments. For residential land uses, the General Plan notes that a noise environment of 55 Ldn or less is "clearly acceptable" while a noise environment between 55 and 65 Ld„ is "conditionally acceptable." Noise levels in excess of 65 Ld„ are "normally unacceptable" for residential uses. Noise is also regulated in San Leandro through the noise ordinance, which can consider the level, intensity, character, and duration of the noise as well as the time and place of the noise in determining whether the ordinance has been violated. Construction activities would intermittently and temporarily generate noise levels above existing ambient levels in the project vicinity. This would mostly affect the residents to the east and businesses in the immediate vicinity. This is a potentially significant impact. MITIGATION: To reduce the construction noise effects, the City will require construction contractors to limit noisy construction activities to the least noise-sensitive times of the day and week (e.g., 7:00 a.m. to 6:00 p.m., Monday through Friday). FINDING: This change has been required in, or incorporated into the Project and will avoid potentially significant environmental impacts as identified in the Initial Study. 7) OPERATIONAL NOISE EFFECT: Stationary mechanical equipment associated with the new apartment building could increase noise levels in the project vicinity. Specifically, this could affect existing residents to the east and proposed on-site residents. Stationary mechanical equipment would include such items as heating/ventilation and air conditioning (HVAC) equipment. This could be a substantial source of noise depending on distance and inclusion ofnoise-reducing features. This is a potentially significant impact. 3
