LSA was retained to prepare an air quality impact analysis and a noise study for the I-15 Base Line Road interchange project located in the Cities of Rancho Cucamonga and Fontana, California. Greenhouse gases and potential air quality impacts were analyzed in the air quality impact report along with the recommended mitigation measures. The noise study identified potential noise impacts and evaluated noise abatement measures. The City of Rancho Cucamonga, in cooperation with Caltrans, the Federal Highway Administration, and the City of Fontana, proposes to construct modifications to the existing Base Line Road and I-15 interchange. The project covers a distance of approximately 0.8 mile. Improvements to the I-15 mainline will extend approximately 2,400 feet south of the Base Line Road centerline and 1,800 feet north of the Base Line Road centerline; improvements to Base Line Road will extend approximately 1,800 feet west of and 1,500 feet east of the I-15 centerline at Base Line Road; and improvements on East Avenue will extend approximately 1,280 feet north and south of Base Line Road. East Avenue would be widened at the approaches to Base Line Road, and the existing I-15 ramps would be modified. Acceleration/deceleration lanes would be added to I-15 in the project area. The purpose of the project is to alleviate existing and future traffic congestion at the I-15/Base Line Road interchange ramps during peak hours to improve traffic flow through the interchange. The study evaluated three alternatives: a No Build Alternative and two Build Alternatives.
