7A - ATTACHMENT NO.3 Saltworks Proposal- Water Group Summary Report (22 January 2010) Page 20 The water team carried out a demand projection based on the land uses, units and square footage values from the OMS Demand Report, but using a method based on the City's Attachment Q which is the standard method used by the City for new or redevelopment projects. This projection shows a potable demand of 1,815 AFY and a non-potable water demand of 1,825 AFY for a total demand of 3,640 AFY, which is approximately 31 percent higher than the OMS projections. The Attachment Q-based analysis performed by the water team is not the City's Attachment Q analysis for the project. It was carried out at this relatively early stage in the project to evaluate the proposed demands relative to the City's standard approach. The actual water demands for the project will be determined by the City as part of a WSA for the project should it move forward in the City's review process. Policy Issues Reaardina Demand · To sustain demand at the Saltworks project at the level of the OMS demand projections, significant and complex enforcement measures would be required. Pre-construction and pre-sale actions could include design guidelines, covenants, conditions and restrictions, resale requirements and City staff for inspection and enforcement. Post-sale tactics could include permits for any changed condition on site, assignment of site-specific water budgets and fines for exceeding these budgets, interface at time of sale, and ongoing City staff involvement. If the Attachment Q demand projections are used these enforcement measures would not be required. · Using recycled water for all planned uses, including school grounds, parks and athletic fields, would require modification of the City's past practice regarding irrigation with recycled water. 13
