The numbers are in for Valley Water’s Great Sign Hunt 2020!

Hundreds of Santa Clara County cyclists rode across miles of creek trails and bike paths earlier this year in search of adventure and Valley Water signs. These determined cyclists covered a lot of ground, tallying more than 1,700 bike rides and locating 4,318 Valley Water signs.

Valley Water and the Silicon Valley Bicycle Coalition (SVBC) hosted this outdoor scavenger hunt, dubbed the Great Sign Hunt 2020. The goal was to find Valley Water signs and report back on their location and condition.

The excitement for this collaborative effort began in July, when more than 350 Santa Clara County residents signed up. When the scavenger hunt ended on Oct. 29, cyclists found 4,318 unique Valley Water signs.

“I had a blast riding around finding the water signs,” said Roy D. “I easily went over 400 miles of riding. From Palo Alto to Gilroy, I went deep into the creek trails and bike paths. I got to see the beauty of our creek trails. Thanks for the fun times.”

Valley Water signage offers essential information about where to go, what to avoid, and often provide interesting facts about our creeks, waterways and environment. However, they’re only helpful if they’re in good condition. The goal of the outdoor scavenger hunt was to help inventory existing Valley Water signage. Through a handy mobile app, participants captured photos of Valley Water signs, noted the condition of the signs and submitted the information to Valley Water.

Throughout the Great Sign Hunt 2020, cyclists were enthusiastic and committed to finding local Valley Water signs; this dedication remained constant despite restrictions implemented under the current health orders, the fall season heatwave and wildfires. Valley Water will use the sign information gathered to improve public safety by prioritizing the replacement of damaged or outdated signs.

“Thanks to SVBC and Valley Water for teaming up for this fun distraction,” Michael G said. “With commuting gone, this has given my rides a purpose and has led me to explore some great new spots.”
