City of Emeryville 40th Street Multimodal Project
Team Members: Diablo: Jennifer Harmon (Project Manager), Garrett Gritz (QA/QC)
Subconsultants: Kimley-Horn (grant support), Fehr & Peers (traffic/signals), Community Design + Architecture (landscape/wayfinding), NCE (Environmental, Geotechnical & Hazardous Materials), and MNS (Surveys/Mapping/Design Support)
Services: Bicycle Cycletrack, Traffic Analysis, Pedestrian Lighting and Signal Modifications, ADA On-street Parking Analysis, C.3 Landscaping, Pedestrian Improvements, Pavement Design and Bus Only Lane
Project Objective:
This is a transformative project that aims to dramatically enhance active transportation and transit use within Emeryville by creating safer and faster routes for residents – as pedestrians, bicyclists and transit riders – to access essential community resources, including the Bay Trail, the proposed 40th Street & San Pablo Bus Hub, MacArthur BART station, and the Bay Bridge Bike Trail. The project will create bus only lanes and a two-way separated Class IV Bikeway with protected intersections along 40th Street and Shellmound Street that will greatly enhance safety and comfort for cyclists.
Project Description:
On 40th Street and Shellmound Street, from Christie Avenue (middle of Emeryville’s commercial core) to Adeline Street (at the Emeryville-Oakland border), the project will improve access to community members. Diablo Engineering Group lead the Team who prepared the environmental assessment, C.3 assessment, landscaping, wayfinding, traffic signal and lighting upgrades, final Plans, Specifications, and Estimates (PS&E). The project required approval from AC Transit, City of Oakland and Alameda CTC. Alameda CTC has a project on San Pablo Avenue that crosses the project. As San Pablo Avenue is Caltrans right of way, the project requires an encroachment permit.
The project provides transit improvements in the form of transit-only lanes, signal priority, and transit islands with shelters to improve bus service reliability and accessibility. Numerous pedestrian improvements are also proposed, including intersection bulb outs and shortened crossing distances, increased sidewalk width, benches, greenery, pedestrian-scaled streetlights, and daylighting, which will increase pedestrian comfort and safety. Bicycle, transit, and pedestrian infrastructure improvements will work in tandem to establish a secure route for all modes of transportation in accessing Emeryville’s essential resources, transit hubs, and the Bay Trail. In providing this secure route for non-vehicular use, the project is transformative in influencing regional travel patterns by promoting healthier and more sustainable modes of travel.
