City of Santa Ana Environmental Checklist conditions), and projected operating traffic conditions with Phase I and Phase II of the project. The TIA also evaluates operating conditions with the project in the near -term for Phase 1(2013), the near -term for Phase 11(2019), and the long -term (2035). Year 2013, 2019, and 2035 traffic impacts are discussed in the cumulative impact analysis in Section XVII, "Mandatory Findings of Significance" and assume annual growth rate factors in the near -term and forecasted traffic conditions from the Orange County Transportation Analysis Model (OCTAM) in the long -term. A description of impacts related to project construction, operation, and parking is provided below. Construction impacts Construction activities are expected to occur within both phases of the project. Construction activities in Phase I would occur for 13 months and for 12 months in Phase 11. Both Phases are expected to generate a short -term, temporary increase in construction related traffic. The estimated number of daily truck trips and number of construction workers needed for construction of the project is provided in Table 2 -3. However, Mitigation Measure AQ -1 limits the number of truck trips per day to 90 trips during the 4 -day excavation and export of soils effort. While specific impacts are not quantified for the project, the number of ADT and peak hour trips associated with project construction would be less than the estimated 463 ADT from operation of Phase I. However, potential morning and afternoon traffic delays related to construction vehicles and could create a temporary /short -term impact to roadways adjacent to the project site. As such, implementation of a construction management plan as described in Mitigation Measure TR -1 would be required to reduce short -term construction traffic impacts to a less - than - significant level. Mitigation Measure TR -1: Prior to issuance of construction permits, the project applicant will develop a Construction Management Plan to be approved by the City of Santa Ana Traffic Engineering Division that will include the following measures: • Designate traffic control for any street closure, detour, or other disruption to traffic circulation. • Identify the routes that construction vehicles will utilize for the delivery of construction materials (i.e., lumber, tiles, piping, windows), site access, traffic controls and detours, and proposed construction phasing plan for the project. • Specify the hours during which transport activities can occur and methods to mitigate construction- related impacts to adjacent streets. • Require the contractor to keep all haul routes clean and free of debris including, but not limited to, gravel and dirt as a result of its operations. The applicant will clean adjacent streets, as directed by the City Traffic Engineering Division, of any material which may have been spilled, tracked, or blown onto adjacent sheets or areas. • Allow hauling or transport of oversize loads between the hours of 9:00 a.m. and 3:00 p.m., only, Monday through Friday, unless approved otherwise by the City Traffic Engineering Division. No hauling or transport will be allowed during nighttime hours, weekends, or federal holidays. Operational Impacts The TIA evaluated the operational impacts for each of the project's two phases and compared the increase to existing baseline conditions as they occurred in January 2012. As such, project traffic generation was developed for each phase, with the second phase including traffic generated by the first phase. The project trip generation was estimated using ITE Land Use 530: High School trip rates and land Use 221: Low -Rise Apartment trip rates, which provides a generation factor of 1.71 and The Academy Charter High School 12 Initial Study /Mitigated Negative Declaration 3-91 June 20 iCF 009202 J
