Grand Avenue Widening Project Environmental Impact Report Section 2.0 The widening of the project segment of Grand Avenue is anticipated to result in increased numbers of vehicles on Grand Avenue which would result in small increases in vehicle related pollutants. During rainstorms, these pollutants may be washed off the road surface and into area storm drains, resulting in a very small incremental degradation of surface water quality. However, small increases in vehicle related pollutants are likely to occur on other streets in the area if the project is not implemented because traffic demand is anticipated to increase with approved development in the area. Therefore, the proposed project will not result in a significant impact related to the quality of surface waters. No mitigation is required. Because there are no fresh or marine water bodies on or adjacent to the project segment of Grand Avenue, the proposed project will not result in changes to river or stream channels or impact currents. Because the proposed project will not result in substantial increases in storm water flows, it will not result in adverse impacts related to surface water bodies. No mitigation is required. Grading activities during construction of the project segment of Grand Avenue will not extend to the depth of groundwater. Construction of the project will not result in any cuts or excavations which would extend to aquifers or the groundwater table. The project area does not currently provide substantial groundwater recharge capability. Therefore, the proposed project will not result in adverse impacts. on the flow or direction of groundwater, impact the quality and quantity of groundwater, or impact groundwater recharge. No mitigation is required. The proposed project will require the use of small amounts of water in the short and long term. Construction related activities will occur over a short period of time, and will require relatively small amounts of water for dust control and other construction activities. Water resources will be required for landscape irrigation in the long term. However, this will not require substantial amounts of water because the majority of the landscaping is expected to be drought tolerant. Therefore, the proposed project will not result in adverse impacts related to groundwater supplies for public water uses. No mitigation is required. 2.6 AIR QUALITY IMPACTS FOUND NOT TO BE SIGNIFICANT The proposed widening project is in an area that is predominantly flat with no substantial topographic or man made features which could alter air movements, moisture or temperature in the area. The widened segment of Grand Avenue will be at grade and well below the height of existing structures in the area. Therefore, this widening project will not alter air movements, moisture or temperature or cause any change in the climate of the area. No mitigation is required. The use of asphalt during construction will generate odors in the short tern, which would dissipate quickly in the air. The proposed project will not result in the creation of objectionable odors because these odors would only occur for a short period of time. No mitigation is required. The widening of Grand Avenue will improve traffic flows, which would reduce vehicle idling and, thereby, decrease odor creating exhaust emissions. As a result, the proposed project will not result in the creation of objectionable.odors in the long term. No mitigation is required. r: L1KUJ-CNVIGrand eirWew Text- GrandlSection 2.0-new.doc page 2-4
