a) Would the project exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? (No Substantial Change from Previous Analysis) The addition of 24 residential units, for a net gain of 10 units from the approved 2005 project, is not anticipated to exceed wastewater treatment requirements. The City of Santa Ana confirmed that adequate infrastructure existed for the project, as modified by the 2009 Addendum. In addition, mitigation measures in the FEIR 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 FEIR. b) Would the project 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 --inch sewer main that was recently constructed in MacArthur Place. More than adequate water and sewer infrastructures have been constructed 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. Additionally, removal of the retail, restaurant, and commercial/residential components of the Cinema Lofts resulted in a reduction in demand for water and sewer usage. Sewer usage by the hotel approved in the 2009 Addendum has been adequately covered by the installation of a 12 -inch line along the hotel frontage. The project, as addended, would result in a sewer demand of 304,204 gallons per day, which is less than .0405 million gallons per day capacity. The project will have no new or more severe impacts beyond those addressed and mitigated in the FEIR. c) Would the project require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? (No Substantial Change from Previous Analysis) As detailed in the FEIR, the previous project was to be entirely developed with impermeable surfaces. The proposed project will also be entirely developed with impermeable surfaces. Therefore, no adverse impact on the existing storm water drainage facilities is anticipated, because the project, as proposed, is substantially the same in terms of runoff from the project analyzed in the FEIR. The project will have no new or more severe impacts beyond those addressed and mitigated in the FEIR, and the FEIR remains adequate and complete. d) Would the project have sufficient water supplies available to serve the project from existing entitlements and resources or are new or expanded entitlements needed? (No Substantial Change from Previous Analysis) As detailed in the FEIR, the City of Santa Ana Water Department provides water service to the MacArthur Place South project area. The data from the Walden and Associates Domestic Water Technical Report for MacArthur Place (Amendment No. 1 ) dated March 3, 2004 and Amended November 19, 2004 was utilized to calculate the originally proposed project impacts on water demand. 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. 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 MacArthur Place South EIR — 2011 Addendum 45
