A-40h, Mater Dei High School Panting Structure and School Expansion Project Environmental Impact Report Construction of the parking structure would involve the voluntary acquisition of 19 existing single - fanuly residential units by the Project Applicant. These 19 residential units are located east of Baker Street and north of St. Andrew Place. Baker Street, between St. Andrew Place and Berkeley Street, would be vacated, providing access from St. Andrew Place to the parking structure and surface Parking lot to the north along a new Monarch Way extension. Additionally, a portion of Occidental Street and Berkeley Street (approximately 250 feet), between Baker Street and the proposed property line, would also be vacated. Occidental Street and Berkeley Street are proposed to terminate at the eastern boundary of the parking structure at a new public alley that would allow for adequate fire access and connectivity between the two roadways. The public alley, to the east of the parking structure would include Mater Dei- controlled gates at both the north end and south end. The proposed gates would have a I {nox Box installed in order to provide for City of Santa Ana Public Works and Orange County Fire Authority (OCFA) access to the site. The gates would also be set back in order to allow a harrunerhead arrangement for vehicles to pull in without blocking the alley. In addition, the proposed gate locations would provide total public access between Occidental Street and Berkeley Street for the City Public Works and Fire Department staff as well as the general public. In order to accommodate the public access portion of the proposed alley, the existing west property line would be modified to shift toward the west between Occidental Street and Berkeley Street. The alley would become City property with the landscape maintained by Mater Dei Iligh School. This public alley would also provide trash trucks access to Berkeley Street and Occidental Street on a weekly basis, and would elirnknate the need for trash trucks to back up. Fite lanes would be provided along the western, eastern, and northern boundaries of the parking structure with access from St. Andrew Place and extending to the west and to the north to the existing fire lanes within the campus. As part of the fire lane, a 30 -foot drainage and utility easement /public alley would be provided along the eastern property line. Six -inch sewer and water mains would be located within the easement /public alley. Existing utilities within Baker Street and the portions of Occidental and Berkeley Streets proposed to be vacated would be relocated. An eight -foot high masonry wall with greenscreening would be constructed along the northern and eastern property lines of the parking structure, adjacent to the existing residential uses. A six -foot wide walkway would be constructed along the northern and western sides of the parking structure. Fencing and landscaping would be provided on Mater Dei Fligh School property to the west of the parking structure driveway at St. Andrew Place, and landscaping would be provided around the perimeter of the packing structure. Travel patterns for students and parents would be altered with the addition of the parking structure. Parents /guardians dropping -off and picking -up students would have a one -way circulation system, similar to existing operations, entering from the north on Edinger Avenue and continuing south to exit onto the new Monarch Way extension at St. Andrew Place. Students parking in the main surface parking lot would have access from Edinger Avenue during the morning arrival only. Students parking in the proposed parking structure would have access only from St. Andrew Place fox entering and exiting. Students traveling eastbound on St. Andrew Place and northbound on Balser toward the school would access the parking structure through the main entrance on the new Monarch Way extension. Students traveling westbound on St, Andrew Place toward the school would have access to the structure via a right -turn only en ranee located at the new utility, drainage, Statement of Facts and Findings 3 June 2015
