Agenda Item No. 5.1
DATE: April 28, 2026
TO: Honorable Mayor and Members of the City Council
FROM: Joan Malloy, City Manager
SUBJECT: Adopt a Resolution Approving the First Addendum to the Certified East West Connector Final Environmental Impact Report for the Quarry Lakes Parkway Project, Phases (Segments) 1-4, City Project No. 18-04
EXECUTIVE SUMMARY
Staff recommends that the City Council adopt a resolution approving the First Addendum to the East-West Connector Project Final Environmental Impact Report – April 2026, for the Quarry Lakes Parkway, Phases (Segments) 1-4, City Project No. 18-04.
This addendum applies to the Environmental Impact Report (“EIR”) that was prepared in 2009 by the Alameda County Transportation Authority and adopted by Union City that same year as a Responsible Agency. In 2018, Union City became the Project Sponsor for the parkway. As Union City prepares to implement Quarry Lakes Parkway Phases 1- 4, an Addendum has been prepared to identify minor modifications or additions that do not alter the EIR's core findings.
STRATEGIC PLAN ALIGNMENT
This agenda item is aligned with the following:
Goal C, Strategy 2: Economic, Community Development and Public Safety – Facilitate the build-out of the greater Station District Area through the construction of the Quarry Lakes Parkway, completion of the pedestrian rail crossing, and implementation of the recommendations of the Southern Alameda County Regional Rail Integration Study to make the Station District a passenger rail hub served by ACE.
BACKGROUND
The Alameda County Transportation Authority (“ACTA”), in cooperation with the cities of Fremont and Union City, proposed a 3.0-mile transportation corridor that would provide east-west access between I-880 and Mission Boulevard (“SR 238”) in southern Alameda County. The “East West Connector” (“EWC”) project would widen existing roads (1.7 miles along Decoto Road and Paseo Padre Parkway in Fremont) and construct a new Agenda Item No. 5.1

roadway (1.3 miles from Paseo Padre Parkway in Fremont to Mission Boulevard in Union City) parallel to Decoto Road, and, upon completion, would provide a continuous bike and pedestrian corridor from I-880 to Mission Boulevard.
ACTA, as the Lead Agency under the California Environmental Quality Act (“CEQA”) and the State CEQA Guideline, prepared the Final Environmental Impact Report (“2009 Final EIR”) for the East West Connector Project (State Clearinghouse No. 200710278) in compliance with CEQA, to assess the potential environmental impacts, describe the alternatives, and the potential mitigation measures. On May 28, 2009, the ACTA Board certified the 2009 Final EIR, dated April 2009, for the East West Connector Project, which is located at: https://www.alamedactc.org/wp-content/uploads/2018/12/00703- 07_RevisedFEIR_V1_2009_Web.pdf.
On June 25, 2009, the ACTA Board considered related Board reports, documents presented by ACTA staff and the ACTA’s environmental consultants, including a Finding of Facts and the Statement of Overriding Considerations for the East West Connector Project, prepared in accordance with the CEQA and State CEQA Guidelines and adopted Resolution No. 2009-004 (“ACTA Resolution”).
In accordance with the CEQA Guidelines Sections 15091 and 15096(h), the City of Union City is a Responsible Agency for the East West Connector Project. On July 14, 2009, the City Council adopted Resolution No. 3838-09, finding that the City is a Responsible Agency pursuant to the California Environmental Quality Act for the East West Connector Project (Route 84, Option 2), and approving the project.
In July 2010, the Alameda County Transportation Commission (“Alameda CTC”) was created by the merger of the Alameda County Congestion Management Agency (“ACCMA”) and the Alameda County Transportation Improvement Authority (“ACTIA”), formerly ACTA, to streamline operations, eliminate redundancies, and save taxpayers’ dollars. As a result of the merger, Alameda CTC can implement more cost-effective planning, funding, and delivery methods for programs and projects that benefit Alameda County residents and businesses.
On March 22, 2018, the Alameda CTC approved the City of Union City's request to serve as the Project Sponsor for the remaining phases of the I-880 to Mission Boulevard/East West Connector Project and to update the project description eligible for the remaining commitment from the 1986 Measure B Transportation Expenditure Plan.
On September 14, 2018, the City of Union City received from Alameda CTC the executed I-880 to SR 238 (Mission Boulevard) East-West Connector Project Funding Agreement (“PFA”) No. A18-0046, in the amount of $2,500,000, identifying Union City to be the Project Sponsor for the Final Design and Construction, and Lead Agency for CEQA documentation, which included revising the design to include transit, bikes, and pedestrian improvements, evaluating the need for a traffic study update, and determining if the 2009 Final EIR was sufficient for project revisions.
On February 12, 2019, the City Council adopted Resolution No. 5444-19, which authorized renaming the I-880 to Mission Boulevard/East West Connector Project to the Quarry Lakes Parkway Project. To better manage the project, the City divided the project Agenda Item No. 5.1

into usable segments or phases that included Phase (Segment) 1: 7th Street Connection (7th Street to Mission Boulevard), Phase (Segment) 2: Gateway Connection (Old Alameda Creek to Alvarado-Niles Road), Phase (Segment) 3: 11th Street Connection (11th Street to 7th Street), Phase (Segment) 4: Alvarado-Niles Connection & Grade Separations (BART and Oakland Subdivision) and Phase (Segment) 5: Paseo Padre Parkway & Bike Trail Connection (Paseo Padre Parkway in Fremont to Old Alameda Creek in Union City).
The Quarry Lakes Parkway, City Project No. 18-04, is funded with 1986 Measure B funds, 2014 Measure BB funds, and other transportation funds administered by Alameda CTC and Regional Measure 3 (“RM3”) Dumbarton Corridor Improvement Program funds administered by the Metropolitan Transportation Commission (“MTC”).
Mark Thomas and Company, Inc., the Engineering Design Consultant, has completed sufficient engineering design for Quarry Lakes Parkway, Phase 1 (95% Plans, see Attachment 1 for Title Sheet) the Quarry Lakes Parkway, Phase 2 (65% Plans, see Attachment 2 for Title Sheet), the Quarry Lakes Parkway, Phase 3 (35% Plans, see Attachment 3 for Title Sheet) and Quary Lakes Parkway, Phase 4 (35% Plans, see Attachment 3 for Title Sheet), which were used to determine the areas of environmental impacts to wetlands, riparian, specifies and waters.
ICF, the Environmental Consultant for the past several years, has prepared the required technical studies and coordinated with the regulatory agencies for the permits from the Regional Water Quality Control Board (“RWQCB”) for water quality certification for wetlands and discharge into Old Alameda Creek, US Army Corps of Engineers for wetlands, U.S. Fish and Wildlife Services for biological resources impacts, California Department of Fish and Wildlife for stream alteration impacts to Line M Channel and Old Alameda Creek/other biological resources impact, and the State Historic Preservation Office for cultural resources impacts.
DISCUSSION
The Environmental Consultant has prepared the First Addendum to the certified East West Connector Project 2009 Final EIR for the Quarry Lakes Parkway, Phases (Segments) 1-4 in Union City, dated April 2026 (see Exhibit A). The First Addendum describes and analyzes the environmental impacts of the proposed changes to Phases 1-4 of Quarry Lake Parkway as compared to the project and impacts analyzed in the 2009 Final EIR to determine if future environmental review was required under the CEQA subsequent review standards outlined in Public Resources Code section 21166 and CEQA Guidelines section 15162.
Section 3.3, Design Changes Since the EWC EIR (referred to herein as the 2009 Final EIR) in the First Addendum, identifies the project changes in detail; below is a summary of these changes. The complete description in the First Addendum of all the proposed changes to the project analyzed in the 2009 Final EIR is incorporated herein by reference. 1) Roadway Changes
The roadway changes have been made to improve bicycle and pedestrian access and include the modification of the Quarry Lakes Drive alignment, the removal of the short street connection from Osprey Drive to Quarry Lakes Agenda Item No. 5.1
City Council Staff Report Page 4 of 5 April 28, 2026
Parkway, modifications to the Alvarado-Niles Road/Lotus Pond Common intersection, and new multi-use trails along 7th Street and Mission Boulevard. 2) Drainage Infrastructure Changes
The proposed water-quality stormwater treatment basin is located adjacent to Quarry Lakes Drive and Old Alameda Creek, and the proposed hydromodification basin is utilizing Old Alameda Creek, which is underutilized.
These stormwater basins were not identified in the EWC EIR. In addition, the planned 84-inch bypass pipeline from the Line M Flood Control Channel to Old Alameda Creek, as described in the EWC EIR, has been redesigned as a smaller 60-inch overflow pipeline.
3) Mitigation for Waters/Wetlands/Riparian Effects
The mitigation area originally identified in the EWC EIR was located within the project limits as onsite mitigation in the Old Alameda Creek area, adjacent to Quarry Lakes Drive. After further design development and cost analysis, it was determined that onsite mitigation was infeasible, so offsite mitigation options were evaluated at the Eagle Ridge East and Manning Ranch properties in Livermore, as outlined in the Habitat Mitigation & Monitoring Plan (HMMP) dated April 2026. These off-site mitigation locations have received conditional approval from the regulatory agencies.
The roadway design changes in the First Addendum to improve bicycle, pedestrian, and transit access and connections have been presented to the Bicycle and Pedestrian Advisory Committee (“BPAC”) since 2019 for comments and discussion with the BPAC members, bike advocates, and the general public (see Exhibit B for List of BPAC Meetings). Project changes in the First Addendum described above have been presented to the City Council for comments and discussion, including with the general public (see Exhibit C for the List of City Council Meetings). The City Council is considering the Addendum in connection with the proposed approval of work related to new off-site mitigation for biological impacts under an agreement with Rocky Ridge, LLC.
FISCAL IMPACT
There is no Fiscal Impact for this action.
