City of Santa Ana Chapter 3. Environmental Impact Analysis for export of soil /excavation material be reduced to a maximum of 60 trips per day, thereby reducing the daily intensity and NOx emissions of Phase 1. Mitigation Measure AQ -2: The City of Santa Ana Planning and. Building Agency will require by contract specifications that construction- related equipment, including heavy -duty equipment, motor vehicles; and portable equipment, will be turned off when not in use for more than 5 minutes. Contract specification language will be reviewed prior to issuance of a grading permit, 3.2.2 Biological Resources The Met IS /MND found that the previous project would result in less- than - significant impacts after implementation of mitigation related to habitat modifications, riparian habitat, federally protected wetlands, and wildlife corridors. No impacts were found to occur related to local policies or ordinances protecting biological resources or habitat conservation plans. The project site consists of an undeveloped but disturbed parcel that appears to have been graded . and routinely mowed. The project site is mostly composed of ruderal (weedy) vegetation consisting of normative grasses and ornamental trees and shrubs. However, during investigations performed as part of the Biological Resources and jurisdictional Delineation Report (1CF' International 2011) for the previous project, approximately 16 individuals of southern tarplant were observed and mapped within the central portion of the project situp The California Native Plant Society designates southern tarplant as a t,ist 18.1 plant, indicating that the plant is considered to be "rare throughout their range and seriously threatened in California (over 80 percent of occurrences being threatened or in high degree and immediacy of threat)" (CNPS 2011). Furthermore, vernal barley is known to occur in mesic grasslands, vernal pools, and alkali flats or depressions, While not observed on the project site, because, of relatively moist conditions, vernal barley is considered to have a moderate potential to occur, Additionally, vernal barley is also known to co -occur with southern tarplant; which was observed on site. The site visits were conducted outside of the known blooming period for vernal barley, which is from March through )une, As such, If this plant occurs on site, it would not have been detectable during the site visits, Vernal barley is classified as sensitive plant species (CNPS 12). In addition, two small wetland areas totaling 0.021 acre (832 feet) were Identified and delineated in the western portion of the project site and are considered to have the ability to support riparian vegetation. However, because the wetlands are so small and not adjacent to one another, they provide limited benefits and potential riparian habitat areas. Furthermore, although the Biological Resources Report determined that no special- status wildlife occurs on the site, the trees within the project site provide potentially suitable nesting habitat forvarioius bird species. Potential impacts on nesting birds may occur if removal ofthe existing ornamental trees occurs during the breeding season (February 15 through September 31). The proposed project would not result in new or additional impacts beyond those previously analyzed in The Met 1S /MND. The locations of biological resources discussed above were within the footprint of the previous project; therefore, even with the increase in development area, impacts are not expected to be greater than those originally analyzed for the previous project. Furthermore, the proposed project would be required to implement at] mitigation measures as proposed in The Met IS /MND, which are listed below. No additional or new significant impacts that were not previously addressed in The Met IS /MND have been identified, and the proposed project would not represent a substantial change from the previous conclusions in The Met IS /MND.
