November 9, 2010 Page 3 through the SCAG Demonstration project and conduct peak period traffic counts to establish the existing conditions at designated study intersections. It is-assumed that the City of Santa Ana will also be able to provide transportation analysis zone (TAZ) level data on existing land uses within the study area for use in understanding existing uses and developing future land use values for trip generation. Based on information being gathered for the SCAG Demonstration project, the traffic report will include an evaluation of existing traffic and circulation conditions at the project study intersections, including: 1) Intersection operating conditions for typical weekday AM/PM peak hour conditions 2) Descriptions of geometric roadway conditions 3) Description of existing transit services in the vicinity of the project site Peak-period traffic counts will be conducted to establish the existing condition at the study intersections. Existing intersection operating conditions (in terms of volume/capacity ratios and level of service) will be quantified using the ICU analysis methodology as adopted by the City of Santa Ana. The budget for the traffic analysis assumes analysis of up to 19 intersections and collection of traffic counts for these locations. Future Conditions. IBI will forecast and analyze future traffic conditions for the "no project" condition and for the "with project" condition for the designated horizon year for the Vision Plan. It is assumed that the future conditions traffic analysis will be focused on the buildout year for the project, and analysis of interim years would not be required. IBI will work with the City of Santa Ana to develop an appropriate forecast of future traffic conditions for the area. It is anticipated that an annual traffic growth factor will be applied to the existing traffic counts to obtain future traffic volumes. Cumulative trips from nearby developments would be added to the base traffic volumes. Graphics and tables will be used to illustrate the future traffic analysis results and to summarize the performance of the study intersections following the implementation of the Vision Plan. Following review and comment by the City of Santa Ana, IBI will prepare responses to comments for one screencheck traffic study and revise the report as appropriate for inclusion into the Draft PER Up to two meetings with the City of Santa Ana and two hearings (Planning Commission and City Council) would be attended by IBI staff.. Task 1.2 Infrastructure Analysis IBI Group will prepare an infrastructure analysis for the EIR that documents the potential impacts and measures to ensure the infrastructure needs are provided for. IBI Group will coordinate with The Planning Center staff, affected public service agencies, and utility purveyors to assess potential impacts of the Vision Plan. The following services, facilities, and utility systems will be considered as part of this evaluation: domestic water service; sanitary sewer service, and stormwater drainage. This work effort will build on the preliminary infrastructure analysis completed as part of SCAG's Demonstration Project. The evaluation will be limited to the Harbor Boulevard corridor only, consistent with the anticipated land use proposals to be developed as part of the Vision Plan. It is assumed that the analysis will address one land use scenario for the Harbor Corridor Plan (alternative development scenarios are not included in the project budget). Up to two meetings with the City of Santa Ana Municipal Services Division, the Orange County Sanitation District, and/or the Orange County Flood Control District and two hearings (Planning Commission and City Council) would be attended by IBI staff. Water Service Analysis IBi will evaluate existing water service capacity and capabilities for the "no project" and "with project" condition for the Harbor Boulevard Corridor Vision Plan. If deficiencies in infrastructure are present, IBI group will identify
