Santa Ana — Garden Grove Fixed Guideway Project Findings and Facts in Support of Findings and Statement of Overriding Considerations • The proposed project would affect access to driveways of four businesses, which would not interfere with driveway capacity or impact business operations. Therefore, a less -than- significant impact related to driveway access would occur. • The Harbor Boulevard /1st Street intersection, which operates at LOS C in the AM and PM peak hour, is the one Congestion Management Program (CMP) intersection within the Study Area. The proposed project would not change the LOS at this intersection. Therefore, a less- than - significant impact related to the CMP would occur. • The proposed project would involve improvements to the surface transportation network. The proposed alignment would not connect to an airport or cause an increase in air traffic. Therefore, no impact related to air traffic patterns would occur. • The proposed project would maintain existing or equivalent emergency access routes and response times throughout the Study Area by retaining the existing street network and connections. The proposed alignment does not pass in front of a fire station, and station locations would not prohibit access to structures. Therefore, a less- than - significant impact related to emergency access would occur. • As a fixed guideway system, the proposed project would facilitate and encourage alternative forms of transportation, including increased use of the local bus system and other transit lines (e.g., Metrolink and Greyhound). Accordingly, the proposed project would promote rather than conflict with adopted policies, plans, or programs supporting alternative transportation and would have no impact on alternative transportation modes. Q. Utilities and Service Systems (page 3 -229 of the EA/DEIR) • The proposed project would not generate wastewater from activity along the alignment or at stations. Wastewater would be generated by the O & M Facility but would not put added strain on existing wastewater treatment capacity. Therefore, a less- than - significant impact related to wastewater treatment and facilities would occur. • The existing drainage pattern of the proposed alignment would not be substantially altered or impacted by the proposed project. Streetcar tracks would be constructed mostly at -grade with the existing street ROW and the PE ROW. The streetcar tracks do not have gutters like a traditional road, but water that falls onto impervious surfaces associated with the track system would be collected and conveyed into the storm drain system by inlets similar to roadway inlets. Stormwater from non - street portions of the alignment may be directed to vegetated swales for treatment before conveyance to the City storm drain. Therefore, a less- than - significant impact related to stormwater drainage facilities would occur. • The proposed project is a transportation facility and would not deplete water supplies. The O & M Facility would use water for maintenance activities (e.g., vehicle washing) and worker hygiene. Implementation of BMPs would ensure that water use would be minimal. Therefore, a less- than - significant impact to water supply would occur. • The proposed project would not generate solid waste from activity along the alignment although standard waste receptacles would be placed at stations. It is not anticipated that streetcar riders would generate new solid waste that would exceed existing planning 17 January 2015
