City of Santa Ana <br />Environmental Checklist <br />During special events, it is anticipated that the proposed project would need an additional 126 <br />parking spaces to accommodate additional visitors. The Wintersburg Presbyterian Church is located <br />across the street from the project site, and as a church and school the two uses have complimentary <br />use patterns that provide for a reciprocal parking arrangement where each site could make use of parking <br />spaces on the other during peak periods of parking demand. Currently, the Wintersburg Presbyterian <br />Church and the Orangewood Foundation are working together to finalize a parking agreement. However, <br />to ensure that impacts related to event parking are less than significant, implementation of an Event <br />Parking agreement is required by Mitigation Measure TR -2. Implementation of Mitigation Measure <br />TR -2 will reduce impacts related to special event parking to a less - than - significant level. <br />Mitigation Measure TR -2: Prior to issuance of occupancy permits, the project applicant will <br />develop and enter into an Event Parking Management Plan that integrates available off - street <br />parking spaces from other available nearby land uses, providing an additional 126 parking spaces. <br />These spaces would be secured for as- needed use by the Academy per agreement between the <br />Academy and parties of the Event Parking Management Plan. Under this plan, Academy special <br />events would be strategically scheduled in order to coincide with periods of low- parking demand <br />for those able to provide additional off - street parking, thus integrating local, underutilized parking <br />spaces into Academy event parking.. <br />b. Conflict with an applicable congestion rrranagernent program, including, but not limited to level <br />ofservice standards and travel demand measures, or other standards established by the county <br />congestion management agency for designated roads or highways? <br />No Impact. The Orange County Transportation Authority (OCTA) is the Congestion Management <br />Agency (CMA) responsible for the creation and implementation of the Orange County Congestion <br />Management Program (CMP), which was last updated in 2011. The CMP establishes a Highway <br />System, which includes a series of intersections and highways throughout Orange County, also <br />known as OCTA's Smart Street network, and establishes minimum performance thresholds for these <br />CMP facilities. The nearest CMP Highway System is located about 1.5 miles northwest of the project <br />site at SR -22 WB Ramps /Harbor Boulevard in the neighboring City of Garden Grove. Other CMP <br />facilities near the proposed project include Harbor Boulevard /1st Street and i -5 SB Ramps /1st <br />Street Projects must demonstrate consistency with the OCTA's performance thresholds on the <br />Highway System if the project is estimated to either generate 2,400 or more ADT or contribute <br />1,600 or more ADT directly onto the Highway System. <br />As shown above under response a., the proposed project would generate a total of 686 ADT during <br />project operations of Phase i1, which is less than the minimum CMP threshold of 2,400 ADT. <br />Additionally, the project site is located approximately 1.5 miles from the CMP Highway System and <br />would not contribute 1,600 or more ADT directly onto the Highway System. As such, the proposed <br />project would not trigger a CMP analysis, and no impact would occur. <br />c. Result in a change in air traffic patterns, including either an increase in traffic levels or a <br />change in location that results in substantial safety risks? <br />No Impact. John Wayne Airport is located about 8 miles to the southeast of the project site, and the <br />Fullerton Municipal Airport is located approximately 11 miles to the northwest (Google Earth 2012). <br />The project is not located within any of the Airport Impact Zones or AELUPs for either airport. <br />Furthermore, the proposed project would develop three -story structures, which would not extend <br />into airspace or be tall enough to result in a change in air traffic patterns or a change in location. <br />The Academy Charter High School 3 99 June 2012 <br />Initial Study /Mitigated Negative Declaration iCF 00914.11 <br />�1 <br />J <br />
