FIRST STREET PEDESTRIAN IMPROVEMENTS PS&E RFP NO.: 10-110 Understanding of Need The First Street Pedestrian Improvements Project, through the use of State and Federal grant funds administered by the California Department of Transportation (Caltrans) Active Transportation Program (ATP), proposes to widen the existing sidewalks along a 1.2-mile portion of First Street between Flower Street and Standard Avenue in the City of Santa Ana. The existing sidewalks within the corridor do not comply with the current Americans with Disabilities Act (ADA) requirements. Portions of the sidewalks are in need of repair, tree roots have lifted sidewalk panels, cross -slopes at driveway crossings exceed ADA maximums, portions of the sidewalks lack adequate clear widths between existing site features, curb ramps do not meet current ADA standards, utility boxes are located within the ramp area of curb ramps, damaged utility box lids create trip hazards, and other non ADA compliant barriers are located along the sidewalks. Exhibit 1 (page 18) documents key issues. The proposed project involves widening the existing sidewalk by three feet on each side of the roadway by reducing the width of the vehicle travel lanes. Improvements will include constructing new widened sidewalks, reconstructing curb ramps, constructing new curb and gutter, reconstructing bus stop pads, creating bulb -outs, reconstructing driveway approaches, resurfacing and/or reconstructing the asphalt pavement in the roadway travel lane adja- cent to the sidewalk widening, restriping travel lanes, installing high visibility marked crosswalks, relocating and/or adjusting existing utility features to grade, relocating street furniture, modifying the pedestrian push buttons and traffic signal loops at the existing signalized intersections, installing a new traffic signal at the intersection with Lacy street, and retrofitting and/or reconstructing drainage structures including catch basins and parkway drains. Along with the above improvements, the project will implement United States Environmental Protection Agency (USEPA) Green Streets standards to the maximum extent practicable. Green Street Best Management Practices (BPMs) are assumed to consist of proprietary biofiltration BMPs such as Modular Wetlands Systems by Bio Clean. APPROACH Project Management The successful delivery of this key project requires a team that is collectively committed to achieving total client satisfaction; provides an exceptional level of experience in roadway, bike/pedestrian pathways, active transportation, utilities, landscape and traffic design; has the depth of expertise and resources to be flexible and responsive; and recognizes the importance of schedule and budget constraints, as well as the requirements for quality. We believe Tetra Tech is offering that exact team for your consideration. Our approach includes assigning experienced and qualified staff to perform the required duties under the direction of our senior Project Manager, Nate Schreiner, PE, QSD.
