tolerant landscaping, and would be constructed with the most up-to-date building code requirements for water efficient fixtures. Based on an average estimated daily water use of 276 gallons per day per residential unit the residential component of the project would generate a demand for 6,900 gallons per day. To estimate school-related water demand, staff evaluated 3- to 5-years of indoor and irrigation-related water use data provided by OSC for two local schools that would have similar operations to the proposed school: 1) Stratford School, an approximately 440- student private school located at 4756 Willow Road and 2) Alisal Elementary School, an approximately 551-student public school located at 1454 Santa Rita Road. Based on the available data, the schools generated a demand of between 20 and 22 gallons of water per day per student. Assuming a conservative per-student water demand rate of 22 gallons per student per day, the 294 students on the site would be expected to generate demand for 6,468 gallons of water per day. Thus the total water demand of the project would be approximately 13,368 gallons per day, a net increase of 5,660 gallons per day over existing conditions. A recommended condition of approval (included in Attachment 1) requires that the applicant receive verification from the Zone 7 water agency confirming that sufficient water is available for the project. Peak-Hour Vehicular Trips The proposed 25 single-family homes and private school would replace the approved church facility which, at build-out, would have a daycare/preschool with an enrollment of 200 children, a 900-seat sanctuary building, and a combined building area of approximately 81,410 square feet. The school is conditioned to retain its current State-licensed capacity of 120 students unless a transportation and circulation study is conducted that shows increased enrollment would not adversely affect local traffic conditions or result in a shortage of parking. Ultimately, the school desires to increase enrollment to 294 students. In order to better understand the traffic implications of the project, staff analyzed trip generation under three scenarios: 1. Existing Conditions: church and existing 120-student school 2. Approved: church site at its built-out condition under current approvals 3. Project, including: a. Proposed — 25 residential units and a private school with120 students b. Proposed Future — 25 residential units and a private school with 294 students Table 2 on the following page shows the AM peak period trip generation for each of these scenarios based on the 9th Edition of the Institute of Transportation Engineers Trip Generation Handbook (ITE). Scenarios 1, 2, and 3a are most relevant to the discussion at this time, since Scenario 3b would require additional traffic analysis by the private school operator, and a license modification from the State. Scenario 3a (proposed — 25 units and 120 student preschool) would result in 27 additional AM peak vehicle trips compared to Scenario 1 Page 9 of 12
