C. Noise With the installatiou of solid walls along the boundaries of selected properties containing sensitive receptors, numerous outdoor residential and school activity areas will be provided with noise attenuation that will meet federal noise level standards. Approximately 9,000 feet of 6 -foot high walls, at an estimated cost of $675,000, would be required. Many homes that currently are subject to noise levels in excess of State and federal standards would be removed, eliminating this existing health hazard. D. Aesthetics By providing a uniform appearance to the public improvements in the project corridor, visual continuity will result, a quality that is lacking in the existing streetscape. Proposed improvements include a substantial amount of additional landscaping within the public right -of -way, which will help soften the harsh and utilitarian appearance of this urban arterial and provide an amenity for the street. The project would also provide an opportunity to place existing overhead utilities underground, thereby reducing the visual clutter of the streetscape. In addition, the smaller remnant parcels could be utilized as a landscaped extension of the public right -of -way, lending a more naturalistic effect to the streetscape. E. Transportation Completion of the proposed roadway improvements would implement both the Orange County Master Plan of Arterial Highways and the Circulation Element of the City of Santa Ana, as they pertain to Bristol Street. Provision of six travel lanes, along with the proposed intersection modifications, would significantly improve the vehicular traffic- carrying capacity and movement efficiency for this heavily travelled arterial. The added capacity which this fully improved six-lane divided roadway would provide would greatly aid traffic circulation by reducing congestion and delay and accommodating projected future traffic increases. Based on experience, a substantial reduction in accident frequency can be expected, due to the proposed extensive use of raised center medians. By reducing the number of locations from which movements can be made across the major through street, raised medians would also improve the flow and traffic - carrying capacity of the roadway. By prohibiting on- street parking throughout this segment of Bristol Street, as proposed, the street would operate more efficiently and with greater safety. This is due to the elimination of potential vehicular conflicts and through the retention of sight distance at intersections and driveways.
