The CCRCD has created a blog page to share latest projects, news, insights, and other informative and interesting facts and events concerning the conservation of resources in Contra Costa County. Click here to see more about our Watersheds.
"The Alhambra Creek Watershed covers approximately 16.5 square miles in north central Contra Costa County in Northern California and encompasses a portion of the City of Martinez. Its upper portions are wooded/grassy ridges and slopes, which collect runoff for three main stem streams. The combined branches flow through valleys containing open space, wildlife habitat, residential and commercial areas, through downtown Martinez and then discharge into the Carquinez Straits through a tidal wetland." (Alhambra Creek Watershed Management Plan, Alhambra Creek Watershed Planning Group, April 2001, p. 24).
The Alhambra Creek Watershed Planning Group has evolved into the Alhambra Watershed Council of today.
Marsh Creek watershed is the second largest watershed in Contra Costa County. It originates on the eastern slope of Mt. Diablo and flows 30 miles through the rapidly growing communities of Brentwood, Oakley, and Antioch in eastern Contra Costa County and into the Sacramento-San Joaquin Delta.
The Rodeo Creek Watershed is located in Western Contra Costa County. Interstate 80 and Highway 4 pass through the watershed. The Cities of Hercules and Pinole are directly to the south and the community of Crockett is to the north.
The Walnut Creek Watershed is the largest watershed in Contra Costa County totaling 146 square miles, or 96,000 acres, in size. The Walnut Creek Watershed has 309 miles of creek channels accounting for almost a quarter of all mapped creek channels in Contra Costa County. The watershed extends from San Ramon to the south, Martinez to the north, Moraga and Orinda to the west, and Concord to the east.

Heidi Petty has been with the CCRCD since 2007. Her current position is Watershed Program Manager and Fundraising Coordinator, focusing on the Contra Costa side of the Carquinez Strait shoreline. In 1999, Heidi started a small bonsai and custom saltwater reef tank business named ‘Through the Looking Glass: A Living Art Studio’ in Crockett, CA, where she got an in-depth understanding of saltwater filtration and hydrology. Heidi has held numerous community leadership positions in the Crockett, Port Costa, and Rodeo area, including President of the local Chamber of Commerce and Board Member on the Crockett Community Services District. Her entrepreneurialism and government service background makes her a valuable asset to the RCD as a special government district.
She now lives on the river in Oakley, CA, and owns a marina and small urban farm as well as a 28-acre Highlander Cattle Ranch in the SF Delta. She is excited to expand her work by partnering with the technology industry to create innovative ways to help the environment through long-term partnerships and connecting tech to her restoration work.

Fun Fact: Enjoys collecting more plants than he can fit in his yard, loves learning about restoration projects around the world for inspiration.
Evan developed a love of nature as a kid catching lizards and building forts in the canyons of suburban San Diego. This deep interest in the natural world evolved into a focus on the human relationship with nature. Following this interest, he studied Environmental Science at UC Berkeley and Environmental Horticulture at Merritt College in Oakland. He spent several years working in retail plant nurseries before obtaining a master’s degree in Regenerative Studies (environmental sustainability by another name) at Cal Poly Pomona. This led to an extremely rewarding position as a garden educator at an elementary school in an underserved community in Pomona, CA, growing his love for environmental education work.
Working as a California native plant horticulturist at California Botanic Garden in Claremont, CA, then caused Evan’s interest in ecological restoration to blossom. He considers restoration to be a crucial pursuit for preserving biodiversity, mitigating climate change, and fulfilling people’s desire to heal the natural world. He worked several years as a restoration technician on projects throughout the Bay Area and is excited to be involved in community-focused watershed conservation with CCRCD.
Skills: Environmental education, community engagement, research processes, insect identification, report writing.
Fun Fact: Victoria competes in triathlons and will hike or bike up any hill/mountain she can get her feet or wheels on. She summited Haleakalā in Maui, HI on bike in the summer of 2021. Her next challenge is pending. Victoria also loves to cook and create random dishes from available seasonal produce.
Victoria (she/her) is from Orange County, CA. She graduated in 2021 from University of California, Davis with a BS in Environmental Science and Management with an emphasis in Natural Resource Management and a minor in Insect Biology. She participated in a research lab at UC Davis exploring the impacts of human development on insect/plant relationships over time. Following this, she worked as an environmental consultant to identify and resolve soil and/or groundwater contamination to protect water resources throughout the Bay Area.
Victoria grew up helping her dad weed and tend to his extensive vegetable and fruit tree garden and spent many family vacations camping in various national parks. Victoria considers herself very lucky to have grown up with access and connections to the outdoors and wildlife. She understands the importance of access to healthy, natural places for individual and community wellbeing. Victoria is excited to work with CCRCD and partners to help achieve more safe, accessible, sustainable, and functional natural areas regardless of community wealth, race, or composition.
