3.0 Environmental Impact Checklist d) Expose sensitive receptors to substantial pollutant concentrations? Less-than-Significant Impact with Mitigation Incorporated. Project construction would result in a temporary increase in localized emission of dust and diesel exhaust during construction, which is expected to last 16 months. Existing residential uses (sensitive receptors) surrounding the project site may be temporarily impacted.The closest sensitive receptor is a two-story apartment building located adjacent to the project site approximately 13 feet southeast from a proposed project structure.Other sensitive receptors also located in close proximity to the project site include: a two-story apartment building located adjacent to the project site approximately 35 feet northwest from a proposed project structure, and single-family residential homes across Kentfield Avenue approximately 50 feet from the project site. AIthough grading and construction activities would be temporary, they would have the potential to be a nuisance and cause health impacts. Particulate matter(PM1o)is the pollutant of greatest concern associated with dust from construction activities, and if uncontrolled,PMio levels downwind of actively disturbed areas could possibly be locally elevated,impacting the nearly sensitive receptors. Construction control measures identified in Mitigation Measure AIR-1 would minimize construction impacts on nearby sensitive receptors by reducing dust and exhaust emissions to less than significant levels. e) Create objectionable odors affecting a substantial number of people? Less-than-Significant Impact. Construction During construction and grading, diesel-powered vehicles and equipment used on-site could create localized odors. These odors would be temporary and would dissipate in the outdoor construction environment. Construction-period odor impacts would be less than significant. Operation According to the BAAQMD CEQA Guidelines, objectionable odors are typically emitted by industrial and commercial operations such as wastewater treatment plants, sanitary landfills, petroleum refineries, chemical factories, and pain and coating operations. Given the nature of the project as a residential development, operation impacts would not generate objectionable odors.
