Friends of Alhambra Creek

Alhambra Way Mural

This project was spearheaded by Jeff Sherwin, a Friends of Alhambra Creek member and Martinez resident. Jeff's vision and dedication transformed the blank, gray walls of the Highway 4 underpass on Alhambra Way into the current vibrant mural. The mural celebrates some of our remarkable local plants and animals.

Tim Hon, Steve Ha, Romali Licudan, and Eric Nodora make up the local art group, Illuminaries, who painted the mural, along with help from volunteers.

The mural was completed in January 2024.

What Are the Friends Up To?

Your place to find the latest information about the Friends' projects and events. Photos from these projects and events have been added to the Photo Gallery at the bottom of this page.

Sponsored by: City of Martinez, Martinez Refining Company, Kiwanis, Friends of Alhambra Creek, Republic Services, Martinez Chamber of Commerce.
The community cleanup of Hidden Lakes Park was a huge success. There were 42 volunteers who canvased the area and picked up 72# of trash. We had Boy Scouts, Girl Scouts, Kiwanians, Martinez Refinery Company employees, and many people from Martinez and neighboring Pleasant Hill and Concord. Martinez City Council member Satinder Mali led the charge, even taking one for the team as he stepped into the lake, unexpectedly, for a plastic drink cup!
The event follows a similar clean up in downtown Martinez on February 3rd. That clean up netted 57# of garbage. Clearly there is always a need for garbage pick up.
PLASTIC remains a problem! There were bags of plastic Easter grass and eggs along with pink foil pacifiers- perhaps from a gender reveal party.
PLEASE remember to pick up after your parties and try not to use plastic for your decorations. We all know how damaging it is for our environment and the critters who share our world.

On 10/1/2023, the Friends participated in the WARD STREET PARKLET CLEANUP: Thanks to our City of Martinez Mayor Brianne Zorn for spear heading our cleanup of the Ward Street Parklet. Lots of work was accomplished by our small but mighty group. District 1 Councilman Jay Howard was first into the creek. We removed tires, cushions, lots of buckets of garbage, ivy, blackberries and invasive weeds. Our dumpster was filled in three hours! To date the area remains a nice place to view the creek and has become less of a flooding hazard. Martinez city workers keep the waterway clear of downed trees. Photos are below at the end of the page in he photo gallery. Friends of Alhambra Creek out there making a difference!

On 01/21/23, the Friends participated in a CCC Flood Control District planting event called Giving Natives a Chance in Concord, CA.

On 11/19/22, the Friends added native pollinator plants to the Alhambra Native Plant Trail, provided by funding from the Kiwanis Club of Martinez.

On 09/25/22, the Friends partnered with Mt. View Sanitary District and CCRCD for Coastal Cleanup Day 2022 at McNabney Marsh

On 9/25/21, the Friends removed stinkwort and trash from McNabney Marsh in Martinez.

On 9/18/21, the Friends partnered with Green Team to remove stinkwort and trash from the parking lot near the Martinez Dog Park.

On 7/24/21, the Friends partnered with Green Team to remove stinkwort along the walking trail behind the NorCal Courts near the Martinez Shoreline.

Friends of Alhambra Creek was featured in the June 2021 Wildland Volunteer Network bulletin by the California Invasive Plant Council.

The Alhambra Native Plant Trail

Creekside Property Management

Having a creek or waterway flowing along or through your property can be a blessing, but it comes with various potential challenges. According to Contra Costa Public Works, "If your property has a creek or a waterway flowing through it, it is your responsibility to maintain it. Typically private property extends to the center of the creek and not just to the fence line. These privately owned creeks are an important part of our county’s drainage system and are regulated by County ordinance, but they are not maintained by the County." To read more about your responsibility as a private creek owner from the county, visit this Private Creek Maintenance page.  

Here is a list of resources that may be helpful to you as a creekside property owner:

Please note, any work to alter a creek (widening, filling, dredging, reinforcing banks, etc.) may require permits from the County, the Department of Fish and Wildlife, the State Regional Water Quality Control Board, and the US Army Corps of Engineers. Contact these regulatory agencies for more information.
