EXHIBIT 4 ■ This alternative would achieve all project objectives Finding: The City of Santa Ana finds, based on the Final FIR and the whole of the record, that the 120 South Alternative is less desirable than the proposed project. Specific economic, legal, social, technological, or other considerations, including considerations for the provision of employment opportunities for highly trained workers and the effects to the community, make this alternative less than desirable than the proposed project. Public Resources Code § 21081[a][3], Guidelines § 15091[a][3]). D. Revised Construction Alternative The operation of heavy earthmoving equipment would substantially elevate noise levels near residential areas and schools (considered sensitive noise receptors) over several months; therefore, construction noise is considered significant. This alternative would reduce the number of heavy earthmoving equipment and construction activities occurring daily and extend construction schedule as shown in the table below, and would reduce construction -related noise impacts. In most cases the pieces of equipment would be reduced by half and the duration of each phase of construction would be doubled. Revised Construction Alternative Right -of -Way Clearance Demolition of Existing Structures 2 backhoes and 1 front- 3 months' 1 backhoe and 1 front- 6 months' end loader end loader OHE Removal 2 cranes and 1 pole- 6 months' 1 crane and 1 pole- 12 months' pulling machine pulling machine 2.

' ROW clearance, demolition, and removal of buildings, pads, and poles would be done over 3 to 5 years as parcels are acqulred by the City. 2 Duration is for each side of the street required for widening in 0.25-mile segments. For example, laying pavement would take 17 days for a 0.25-mile section on the north side of Warner Avenue and another 17 days for a 0.25-mile section on the south side of Warner Avenue. Facts in Support of Finding: ■ Impacts related to construction transportation and traffic — one of the two significant and unavoidable impacts — would be greater than for the proposed project. All other environmental topics would be similar to the proposed project. Construction noise impacts would be reduced, but not to less than significant levels. Impacts would remain significant and unavoidable. ■ This alternative would achieve all project objectives CEQA Findings of Fact -16 - Warner Avenue Improvements & Widening from Main Street to Grand Avenue Aug 2015 75B-28
