​Friends of Concord Creeks (FCC) is an all-volunteer group dedicated to stewarding waterways and natural spaces throughout the City of Concord, CA.
​
We aim to:

• keep our creeks free of trash,
• monitor the water quality in our creeks, and
• remove invasive species from streambanks and re-plant with native plants.
  ​

Please join us! For more info, please email [email protected].
​And, if you're on Facebook, please check out our FCC group here.

​Which Creeks Flow through Concord?

• Walnut Creek is the main stem of the Walnut Creek Watershed, bordering the Iron Horse Trail as it passes through the northwest corner of Concord before draining to Suisun Bay.
• Pine Creek is a major tributary of Walnut Creek, joining the main stem just north of the Six Flags Hurricane Harbor water park after passing by Meadow Homes Park and Lime Ridge Open Space on its way through the southwestern portion of Concord.
• Galindo Creek is another major tributary of Walnut Creek, joining with Pine Creek just north of Meadow Homes Park. Galindo Creek is a prominent channel passing through Markham Nature Park and Newhall Community Park as it traverses the south central part of Concord.
• Mount Diablo Creek is the main stem of the Mount Diablo Creek Watershed, passing through Brazil Quarry Park and Thurgood Marshall Regional Park (not yet open to the public) in the northeastern part of Concord.

Concord Creeks, as with most urban creeks, provide essential water, food, and shelter for many types of wildlife. Here are some of the species we've encountered in Concord.
