Project overview

More reliable water storage is coming to the Forest Park neighborhood. The Water Bureau plans to build a new 175,000-gallon steel water tank to increase the amount of water available for firefighting and earthquake preparedness. This tank is an integral part of a larger effort to improve water supply  to the city’s west side. In addition to replacing the tank, which will keep people’s homes safer from fire, we’re dedicated to protecting the surrounding natural recreation area for the community.

We plan to replace the smaller of the site’s two existing water tanks with a larger tank. We will also remove an outbuilding known to some as the Willis Building. This building is not ADA accessible, does not have sanitary plumbing, and is unsafe. The new tank will be built in the area where the outbuilding has been removed.

Why

The tank we’re replacing is in poor condition. This tank scores lowest among all active tanks in the Water Bureau’s assessment system. The interior of the tank and the tank foundation are in very poor condition. The tank is not anchored to its foundation, which could make it susceptible to movement in an earthquake. Our engineers estimate that without significant work, the tank will fail in 10 years. The new tank will help the system serve the neighborhood for decades to come as our city’s population grows and climate change affects water demand.

Where

The Greenleaf site is at 360 NW Greenleaf Road, at the southern end of the Forest Park neighborhood.

When

The new tank is currently being designed. The design process will continue through 2023. We expect construction to start in 2024 and continue through 2025.
