As detailed in the Amended Domestic Water Technical Report for MacArthur Place the Doubletree hotel had a demand coefficient of 180 g/d/rm. This same demand coefficient was used to calculate the proposed hotel's water demand, as detailed in the table below. Water Demand of Proposed Hotel Demand Demand Land Use Rooms Coefficient (gallonslday) Proposed Hotel 185 180 gld/rm 33,300 Updated Water Demand Increase in Water Demand from the Proposed Project Water Demand Gallons per Day (gallons per day) Previous water demand (per EIR) 354,535 Reduction in water demand from -7,779 380,056 removed project components -354.535 Additional water demand from +33,300 25,521 185-room hotel Total updated water demand 380,056 As detailed in the table above, the reduction in water demand from the removed project components plus the additional water demand from the proposed hotel result in an updated water demand of 380,056 gallons per day. The proposed project will increase the water demand by 25,521 gallons per day compared to the previous project. The updated water demand of 380,056 gallons per day converts to 426 acre feet per year, which is an increase of 29 acre feet per year compared to the previous project. As detailed in correspondence with the City of Santa Ana Planning Division and Public Works Agency, more than adequate water and sewer infrastructures, and services and laterals, have been constructed at the proposed hotel project frontage that can meet the project's water and sewer needs. A Sewer Study will not be necessary. Four 1-inch water meters, one 2-inch water meter, and a 6-inch sewer lateral are available at the project's frontage in MacArthur Boulevard. A 6-inch water vault and meter and an 8-inch fire service are also available. Additionally, as detailed in the EIR, at 2020, the City's overall water production would be 55,370 acre feet per year. Between 2010 and 2020 the City's water production would increase by 2,410 acre-feet per year. The increased amount of water production between 2006 and 2020 would accommodate the increased water demand generated by the Resolution No. 2009-025 MacMl~leb®~outh EIR Addendum 50
