St. Barbara Catholic School Project No.: D-6289-01 California. More specifically, it is located at 5306 W. McFadden Aven Santa Ana, California. Site Geologic Conditions CITY OF SANTA ANA Planning and Building Agency may, lS. Approved FOR PERMIT ISSUANCE The Newport Beach Quadrangle lies within the broad southern margin of the Los Angeles Basin which culminates abruptly at the Newport -Inglewood Uplift. This uplift is locally characterized by broadly warped coastal mesas composed of late Pleistocene marine terrace deposits. The coastal mesas are deeply incised by antecedent drainages of the latest Pleistocene to earliest Holocene age associated with the regional river systems. Access to the coastal section of the quadrangle is provided by Pacific Coast Highway (State Highway 1). The San Diego Freeway (405) intersects the northeastern corner of the quadrangle and provides access to the inland sections along Bolsa Avenue, Bolsa Chica Street, Warner Avene, and Golden West Street. The project site is located within the State of California Seismic earthquake zone of required investigation. The site is located within the seismic liquefaction zone but does not lie within the landslide hazard zone. Also, the site is not located within Fault Rupture Hazard Zone (Hart, 1997). Surface Water and Site Surface Drainage Surface water on this site is the likely result of precipitation or surface run-off from surrounding sites. Overall site drainage is in a southwest direction to the street. Provisions for surface drainage will need to be accounted for by the project civil engineer. It should be noted that the soil is susceptible to excessive erosion if exposed to running water. We recommend that all surface runoffs should not be allowed to pond. Collected water should be conveyed via a non -erosive device to a suitable storm drain system. 2
