Summary The City of Santa Ana (City), in conjunction with the California Department of Transportation (Caltrans), District 12, proposes to widen Fairview Street between 9th Street and 16th Street, including replacing the Fairview Street bridge crossing over the Santa Ana River (proposed Project) in Santa Ana, California. The purpose of the project is to reduce congestion and improve pedestrian and bicyclist safety on Fairview Street between 9th Street and 16th Street, consistent with the Orange County Master Plan of Arterial Highways and the City's General Plan Circulation Element. South of 9th Street, Fairview Street provides three lanes in each direction, which are reduced to two lanes in each direction north of 9th Street, across the existing four - lane bridge, to 16th Street. The Fairview Street segment between 9th Street and 16th Street is the only constraint for Fairview Street to be built out to its planned width of six lanes. This condition causes a traffic "bottleneck" during peak hours. In addition, there are no sidewalks, bikeways, or lighting on the existing bridge. Pedestrians and bicyclists currently use the roadway shoulder to cross the bridge. A Type 1 project, as defined by Title 23, Part 772, of the Code of Federal Regulations (23 CFR 772), is any proposed Federal or Federal -aid highway project for the construction of a highway on new location, the physical alteration of an existing highway where there is either substantial horizontal or vertical alignment alteration, or other activities listed as a Type 1 project. The proposed Project is considered a Type 1 project because one additional travel lane in each direction would be added on Fairview Street. A noise analysis is required for all Type 1 projects. Existing land uses in the project area include single-family and multifamily residences, a medical office, a park (Fairview Triangle Habitat Restoration Park), a multi -use trail, vacant land, and office, commercial, and light industrial uses. The primary source of noise in the project area is traffic on Fairview Street. The terrain in the project area can be separated into four areas: • Land uses east of Fairview Street and south of the Santa Ana River include single- family and multifamily residences, vacant land, and commercial uses that range from 3 feet (ft) higher to 7 ft lower in elevation than Fairview Street.
