below. Mitigation measures were designed to minimize potential impacts to utilities and service systems. The project will have no new or more severe impacts beyond those addressed and mitigated in the EIR. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? (No Substantial Change from Previous Analysis) Mitigation measures were designed to minimize potential impacts to utilities and service systems. As detailed in correspondence with the City of Santa Ana Planning Division and Public Works Agency, the proposed hotel project sewer discharge need will be addressed by a new 12" sewer main that was recently constructed in MacArthur Place. More than adequate water and sewer infrastructures have been constructed by the project applicant at the proposed hotel project frontage to meet the project's water and sewer needs. The data from the Walden and Associates Domestic Sewer Technical Report for MacArthur Place dated March 3, 2004 and revised January 14, 2005 was utilized to calculate the proposed project impacts on sewer demands. The following components will not be a part of the proposed project: retail, restaurant, and commercial/residential components of the Cinema Lofts. The sewer demand calculation for those uses is detailed below. The table illustrates that the land uses eliminated will result in a reduction in sewer demand of 6,154 gallons per day. Reduction in Sewer Demand Square Feet Demand Demand Land Use (SF)Nnits (du) Coefficient (gallonslday) Cinema Site Commercial 10,000 SF 50 g/ksf/d 500 (Cinema Lofts) Cinema Site Residential 15 DU 215 g/d/du 3,225 (Cinema Lofts) Restaurant 8,590 SF 175 g/ksf/d 1,503 Retail 5,291 SF 175 g/ksfld 926 Total - - 6,154 The project proposes to add a 185-room hotel. As detailed in the Domestic Sewer Technical Report for MacArthur Place, the Doubletree Hotel had a demand coefficient of 150 g/d/rm. This same demand coefficient was used to calculate the proposed hotel's sewer demand, as detailed in the table below.

The table below illustrates the increase in sewer demand for the proposed project. Resolution No. 2009-025 Macl~leb®`South EIR Addendum 48
