m e m o r a n d u m DATE: January 24, 2025 TO: Mr. Ruben Castañeda, Senior Engineer, Public Works Agency – Traffic Engineering City of Santa Ana FROM: Deepali Chausalkar Sandipan Bhattacharjee, PE, TE, AICP, ENV SP SUBJECT: Footlab – Focused Traffic Analysis Translutions, Inc. (Translutions) is pleased to provide this focused traffic analysis discussing the trip generation and levels of service for the Footlab project to be located at 400 W. Warner Avenue in the City of Santa Ana. The site includes an existing building that is classified as a light industrial use. PROJECT DESCRIPTION The project is an atypical land use and the site includes an existing building that is classified as a light industrial use. The project is located at Southwest corner of W Warner Avenue and S Birch Street in the City of Santa Ana. The project includes the reuse of a existing 57,705 square foot industrial building on a 5.18-acre lot as a soccer training facility. Access to the project will be provided via three driveways with Driveway 1 and Drive 2 on W Warner Avenue and Driveway 3 on S Birch Street. All three driveways are unsignalized. Figure 1 illustrates the site plan. STUDY AREA Based on discussion with City staff, the following study area intersections were evaluated for levels of service: 1. Project Dwy 1/Warner Ave; 2. Project Dwy 2/Warner Ave; 3. Birch St/Warner Ave; 4. Project Dwy 3/Birch St; ANALYSIS SCENARIOS The following scenarios were included in the analysis: 1. Existing Conditions. 2. Existing With Project Conditions. PROJECT TRIP GENERATION Since the project is an atypical land use, based on discussion with the City, the trip generation for the proposed project was based on surveys conducted at three similar facilities – TOCA in Costa Mesa, Momentous in Irvine, and The Map in Garden Grove. The resulting trip generation rates were used to calculate the trip generation for the proposed project. The survey data is included in Appendix A. Table A shows the peak hour trip generation as well as the trip generation rate for the three survey sites. The trip generation rate across the three sites was averaged to calculate the trip generation rate for the proposed project.
