First Street Multimodal Boulevard Study February 17, 2026 Page 10 City rehabilitation project and Caltrans' Freeway Ramp Active Mobility Enhancement Study (FRAMES) concept. This configuration is consistent with the vision and design standards included in the Metro East Mixed-Use Overlay Zone. The Fact Sheet for the East Side Concept is provided in Exhibit 7.

Detailed traffic operational results are included in Exhibit 1. Key findings include: • All concepts generally operate at acceptable levels of service in the opening year with targeted intersection improvements; • Some intersections experience increased delay under lane-reduction scenarios, particularly near freeway ramps; • End-to-end travel times increase slightly under the five-lane concept and increase significantly under the four-lane concept; • East-side four-lane configuration operates acceptably in both opening and design years; • Long-term traffic patterns will be further evaluated in coordination with OCTA to account for potential traffic redistribution. EVALUATION OF CONCEPT BENEFITS Using the goals of this project, input and feedback from the community, and the technical analysis conducted to date, a comparison of the benefits for each concept was developed. The comparison ("Harvey Ball" rating) is based on how each concept improves conditions by mode compared to the existing conditions. The table below summarizes the results of this exercise (full shade = meets goal; not shaded = does not meet goal).
