UP!dating with a bold new vision!

Rising construction costs—driven by recent LA-area wildfires, global tariffs, and inflation—pushed the professional cost estimate for our original expansion vision to $20 – 22 million, well above our original $15 million target. At the same time, a shifting political landscape has put key sources of public funding on pause, making bold creativity essential.

Rather than stall progress, we’re forging ahead with a powerful, phased approach. Phase I launches an exciting new chapter: a 7,400-square-foot building that more than doubles the Museum’s current footprint, bringing us dramatically closer to unlocking the full potential of the Children’s Museum. It’s an ambitious move, and the momentum is real with 94% now raised towards our new $8M goal.

Our new vision for the expansion features a new 7,400 sf2 two-story building that includes:

  • An immersive ocean-themed environment  
  • Hands-on STEM exhibits  
  • A maker space where kids can creatively use real tools to build whatever they can imagine  
  • A large-scale physics ball-and-ramp maze 
  • Two dedicated learning lab flex spaces to support field trips, camps & programming workshops
  • Outdoor entryway courtyard 

In addition, the expansion will triple the number of interior restrooms (from 2 to 6) and provide better support for team members and space to store and prep supplies for programs and exhibits. More space will expand experiences that engage children ages 8-12 and offer much-needed relief from overcrowding.

Fundraising Progress: $7.5M Raised

$10.1M$8.6M$7.1M$5.6M$4.1M$2.6M$1.1M

We have been thrilled to receive several generous commitments over the past few months from community leaders, including Connie Codding, Herb Dwight, the Donald & Maureen Green Foundation, Vic Trione, Jennifer & John Webley, and Andy & Sam Werback. In addition, the Mendocino Lumber Company has pledged to donate all the lumber needed to build the expansion.

The Saba Foundation has also stepped forward with a transformational challenge, pledging to match all donations to the Unlock Potential! campaign received by June 30, 2026, up to a total of $620,000.

We are deeply grateful for their investment in Unlock Potential! Campaign and invite you to join them.

Project Progress

  • Site plans are in progress and will be submitted to the City of Santa Rosa by September 2025.
  • The Museum anticipates that the project will break ground on construction by the end of 2026 and be completed in early 2028.

Exhibit Sneak Peek: Explora

Alongside the immersive Aquatica ocean-themed exhibit and the Hammer & Saw Shed maker space, Explora offers children the opportunity to engage deeply with complex science concepts in a hands-on, interactive environment.

In Explora, children dive into hands-on experiments that bring science to life. At the Revolving Circles exhibit, they explore centripetal force, while the Bernoulli Blower invites them to experiment with air pressure and lift. Kids experience the dynamics of air pressure and wind currents at a Tornado Maker, while at the Plane Launch exhibit, kids discover how gravity influences flight and trajectory. A Pin Wall invites children to press their entire bodies into the exhibit, creating 3D impressions while exploring textures, pressure, and spatial awareness.
