The East Bay Regional Park District is gathering public input via an online survey regarding future improvements at Contra Loma Regional Park. The district aims to determine the future of aquatic features following the lagoon's closure.
Why it matters
The survey follows the closure and subsequent draining of the Contra Loma Swim Lagoon due to maintenance and engineering challenges. Officials are evaluating options for the site after the water district constructed the original facility in 2003.
Repair cost estimates for the swim lagoon range between $10.6 million and $14.51 million. A potential reopening of the facility is projected to take approximately 3 to 4 years.

The details
While the swim lagoon remains closed following its 2022 shutdown and 2025 draining, the park district has already introduced new fishing docks, a boat launch, and ADA-accessible picnic sites. The current survey process is open to residents to help guide the site's long-term development.
