Grand Avenue Widening Project Environmental Impact Report Section 3.0 Impacts of Alternative 2 Related to Cultural Resources Impacts of Alternative 2 Related to Archeological Resources There are no documented archeological resources in the Grand Avenue project limits under Alternative 2. Therefore, Alternative 2 will not result in adverse impacts on any documented archeological resources. No mitigation is required. The construction of Alternative 2 could result in adverse impacts on previously unknown buried archeological resources. These impacts will be mitigated to below a level of significance based on implementation of measures CR -1 to CR -6, described later in this section. Impacts of Alternative 2 Related to Historic Resources As discussed earlier, there are no important significant historic resources as defined under the thresholds of significance within or adjacent to the project limits for Alternative 2. Therefore, Alternative 2 will not result in adverse impacts on historic resources as defined under the thresholds. However, as discussed earlier, the updated analyses conducted in December 2001 indicate that the residences at 702 and 714 North Grand Avenue appear to be eligible for listing in the Santa Ana Register of Historical Property. Although not defined as such in the thresholds provided earlier, properties on and eligible for listing on the Santa Ana Register are considered significant and important resources in the City. Therefore, the removal of these structures as a result of Alternative 2 would be a significant adverse impact of the proposed Grand Avenue widening. Mitigation measure CR -7 is provided later to address the impact of Alternative 2 on these structures. The construction of Alternative 2 could result in adverse impacts on previously unknown buried historical resources. These impacts will be mitigated to below a level of significance based on implementation of measures CR -1 to CR -6, described later in this section. 3.7.5 MITIGATION RELATED TO CULTURAL RESOURCES The following mitigation measures are recommended during construction of the proposed Grand Avenue widening, under Alternatives 1 and 2, to reduce potential impacts on cultural resources: CR -1 The project specifications shall require the project contractor to have an Orange County Certified Archaeologist present at the pre -grading meeting to discuss cultural resources monitoring, artifact collecting and safety procedures. At that meeting, the archaeologist will review the construction plans and schedule. CR -2 The project specifications shall require the project contractor to retain an Orange County Certified Archaeologist to conduct part-time monitoring during grading activities to observe and retrieve any buried artifacts that may be uncovered.
