Zoo Update—Work Comes to an End

On April 30, 2025, the Sacramento Zoological Society (Society) and the City of Elk Grove announced that planning for the Elk Grove-Sacramento Zoo is ending. The Society shared with the City of Elk Grove that they no longer see efforts to build a new zoo in Elk Grove as viable.

City officials appreciate and understand the concerns expressed by the Society and accept the decision to cease efforts on the project. The City of Elk Grove and the Society began their joint efforts in 2021 with the bold dream and vision of building a high-quality zoo in Northern California.

More information about the conclusion of this effort is available in the announcement and in the Q&A and video below.

Frequently Asked Questions

When did the project start and what has been accomplished to date?

The City and Sacramento Zoological Society (Society) have been working on building a new zoo since September 2021 when the organizations entered into an exclusive negotiating agreement to consider the project. The Elk Grove City Council approved the project in May 2024. A cost sharing agreement between the City and Society was executed in June 2024. Construction design for the on-site facilities and off-site infrastructure necessary to serve the Zoo has been in progress since summer 2024.

Why is the project being discontinued?

The Sacramento Zoological Society (Society) notified the City of Elk Grove that they no longer see efforts to build a new zoo in Elk Grove as viable and have reluctantly made the difficult decision to end work on the project. Factors outside of either organization’s control such as economic uncertainty and increased construction costs have created an unacceptable level of risk for the project. Other concerns expressed by the Society, which they believe jeopardize the project’s long-term success, include questions over future operating costs, scope and scale of phase 1, and the ability to fund future phases.

Did the size of the proposed zoo change?

The City approved the zoo project in May 2024 with a first phase of 28 acres and full buildout of approximately 65 acres of zoological park. This project, both the initial phase and ultimate buildout, was larger than the Society’s current Land Park footprint of about 14 acres. The number of species, exhibits, and features have not changed since then. The Society provided economic analysis in May 2024 that showed they were confident the proposed 28 acres of zoological park was feasible and affordable. No changes have been made in the subsequent design efforts to reduce or eliminate elements from the initial phase. The City and the Society worked hand-in-hand at all decision points.

How much money has already been spent on this project?

To date, approximately $4.5 million has been invested by the City in preliminary project work, including planning, feasibility studies, design and engineering work. 

This amount does not include the purchase price of the property. In 2022, the City purchased approximately 100 acres in south Elk Grove at the northwest intersection of Kammerer Road and Lotz Parkway for $9 million. The City is confident the value of the land has appreciated in value sufficient to offset the project planning and design costs to date. Elk Grove leaders will consider options for the 100-acre project site at a future date. These options could include the potential sale of the property to recoup the costs incurred for the project or other uses that could provide other benefits to the community.

Couldn’t the City have done more to move the project forward?

The City entered into this joint effort with the Sacramento Zoological Society (Society) in good faith with a bold and ambitious vision to relocate and expand the Sacramento Zoo in Elk Grove. The City completed a Financing Plan, Project Schedule and Cost Sharing Agreement that provided a detailed plan to move the project forward to construction. Additionally, a Feasibility Study, Business Plan and Operating Pro Forma were prepared to ensure the viability of the project through both construction and operations. A Cost Sharing Agreement was approved by both the City Council and the Society’s Board of Directors that required significant financial contributions from both the City and Society to make the project a reality. The City has fulfilled all of its obligations under the Agreement and its commitment to completing the project has not waivered. However, the City understands and respects the Society’s concerns regarding the viability of the project and the financial risk it poses.

Why did the City take on such an ambitious project, with all of the associated risks?

The City of Elk Grove is committed to making Elk Grove the best City possible. The City has visionary leadership that is willing to pursue community-changing projects to advance these goals and bring about positive change for the community, including taking calculated and measured risks to achieve its goals. Not all pursuits will come to fruition, but the City will not be deterred in its efforts and will continue to pursue transformational projects that will add to an already outstanding City.

Is there any chance this project could be revived in the future?

Revisiting the project as proposed is highly unlikely. The City and Society are taking steps to terminate their current Agreement.

If future plans are announced for the Sacramento Zoo, the Sacramento Zoological Society Board of Directors will inform the public. 

What happens to the Zoo if the new site is not built?

The Sacramento Zoological Society remains deeply committed to the Sacramento Zoo’s mission of inspiration, education, and conservation, and to planning for the zoo’s future in a way that meets the needs of the animals in their care and of this region. In the coming weeks, the Society will be sharing more information about the future of the Sacramento Zoo, including their plans for the Land Park site, as they navigate this change in course.

I made a financial commitment to the Elk Grove – Sacramento Zoo, what happens to my money or pledge?

The City of Elk Grove is returning all donated funds to the Society, which amounts to approximately $1.9 million. The Society has committed to contacting all donors in the near future to determine whether the donors would like to affirm their donation to the Society or have the funds returned.

How can the community support the current zoo?

The community can support the Sacramento Zoo by visiting, becoming a member, participating in programs, attending events, and donating. Every contribution helps them fulfill their mission of education and conservation and care for the zoo’s animals.

Is the zoo’s current Land Park location AZA accredited?

The Sacramento Zoo has been a member of the Association of Zoos and Aquariums (AZA) and continuously accredited since 1979. AZA accredits only those institutions that have achieved rigorous standards for animal care, education, wildlife conservation and science. Their most recent accreditation renewal was in 2024 and will last until 2029.

Environmental Review

Before approvals of the Zoo can be considered by the City, an Environmental Impact Report, or EIR, must be prepared. The EIR analyzes the potential environmental impacts of the construction and operation of the Zoo. Key steps or milestones in the EIR process include:

  • A Notice or Preparation, which informs the public and other public agencies that an EIR is being prepared for the project.  The City released the Notice of Preparation on November 18, 2022.
  • A Draft EIR, which is a complete document that includes all the analysis, identifies potentially significant effects of the project, and proposes mitigation measures to mitigate potential impacts.  The Draft EIR is made available to the public and other public agencies so that they may provide comments on the analysis.
  • A Final EIR, which incorporates the Draft EIR, includes all the comments received on the Draft EIR and responses from the City on those comments.  It also includes any corrections or revisions to the Draft EIR.  Together, the Draft and Final EIRs make up the whole of the EIR.

On January 5, 2024, the City released the Draft EIR for the New Zoo Project.  Comments on the Draft EIR were due by February 20, 2024.  Response to comments were prepared and are included in the Final EIR, which is available on this webpage.
