EXHIBIT 4 then hauling shall be restricted to no more than 684 miles per day. The demolition debris hauling phase shall not overlap with any other construction phases, including grading. These requirements shall be noted on all construction management plans and verified by the City of Santa. Ana during demolition and grading activities. Finding: Changes or alterations have been required in or incorporated into the project that avoid or substantially lessen the significant environmental effect identified in the Final EIR. These changes are identified in the form of a mitigation measure, presented above. Impact 5.1-4 would be less than significant with mitigation. The City of Santa Ana hereby finds that implementation of the mitigation measure is feasible, and it is therefore adopted. Cultural Resources Impact 5.2-2 Project -related earthwork may result in a substantial adverse change in the significance of an archaeological resource. Facts in Support of Finding: Support for this environmental impact conclusion is fully discussed starting on page 5.2-10 of Section 5.2, Cultural Resources, of the Draft EIR. The project would involve ground disturbance up to a depth of about 30 inches. The total area of disturbance for the road widening is estimated as 24.7 acres. Although, the project site is already disturbed and developed, because of the early development in this area, previously undiscovered archaeological resources could be damaged during construction. The possible destruction of archaeological resources is considered a significant impact. Mitigation Measures CUL-1 Prior to the initiation of project -related earthmoving activities, the City of Santa Ana project manager or their designee shall retain a county -certified qualified archaeologist. The archaeologist must have knowledge of both prehistoric and historical archaeology, and shall remain on call in the event of a discovery. CUL-2 Prior to the start of ground -disturbing activities on the project site, the City of Santa Ana project manager or their designee shall ensure that a qualified archaeologist or another mitigation program staff member has conducted cultural resources sensitivity training for all construction workers involved in moving soil or working near soil disturbance. • Construction personnel, including heavy -equipment operators, shall be briefed on procedures to be followed in the event that cultural remains are encountered by earthmoving activities. • Preconstruction training shall include: o Review the types of archaeological resources that might be found o Review of laws and applicable requirements concerning the protection of cultural resources o Prehistoric or historic cultural resource discovery procedures CEQA Findings of Fact - 7 - Warner Avenue Improvements & Widening from Main Street to Grand Avenue Aug 2015 75B-19
