Our biology and construction teams planned, designed, and implemented revegetation along South Fork Battle Creek in Tehama County, where Pacific Gas and Electric Company removed the Inskip Dam last summer. The dam was installed in 1910 to provide hydroelectric power to the region. PG&E removed the dam and non-functioning fish ladder as part of a larger effort to improve salmonid habitat in this important watershed. The dam required numerous repairs and improvements in recent years due to damage from storms, and it was forecasted to require long-term structural improvements. PG&E removed the dam rather than implement continued repairs.
As a contractor to PG&E, PCI’s role in the project began with refining existing revegetation plans in 2022. In October-December 2025, once PG&E completed dam removal and adjacent grading, PCI installed over 600 native trees and shrubs, ranging from riparian species like western spicebush and willow to upland trees and shrubs such as valley oak, interior live oak, western redbud, ceanothus, and Oregon grape. The plantings are designed to restore diverse habitat along the banks of South Battle Creek, an important salmon-bearing stream, protect against excessive erosion, provide habitat for many bird and wildlife species, and eventually as the vegetation grows, providing beneficial habitat along the stream edge for fish and other aquatic species.
Our team also oversaw hydroseeding with native grasses and worked hard to install about 10,000 square feet of biodegradable coir blanket to protect the streambank until plant cover gets established. Our crew also installed drip irrigation to support upland plants through the challenging first years of establishment.
PCI will maintain and monitor the new plantings during their establishment period, watching for concerns like drought stress or herbivory and adapting our stewardship as needed to make sure this reach of stream is well on its way to supporting the native oak woodland and riparian forest of the region. We are grateful for the opportunity to collaborate with PG&E and other partners to restore native habitat here and throughout northern California.

PCI’s project on the Ten Mile River was highlighted in this Mendocino Voice article, shedding light on the recent successes in coho recovery and restoration in Mendocino County watersheds. Our partners at The Nature Conservatory shared their inspiring perspective and experiences in coho restoration, helping to explain the need for this type of work and the means by which it can be achieved. PCI has had the privilege of supporting The Nature Conservancy, Trout Unlimited, the Mendocino County RCD, NOAA, and CDFW on coho recovery projects. We take great pride in designing and building projects that will benefit fish, wildlife and local communities for generations to
come.

Conservationists say rebuilt floodplains, wetlands and river habitats are allowing endangered coho to survive — and thrive — once again.

Congratulations to Cesar on Conservation Corps North Bay Corps Member of the Year! Cesar joined PCI last summer and has been an incredible addition to the team!

From student to professional! 🌿 Cesar V., the CCNorthBay Marin Corpsmember of the Year, turned a year of opportunity into a transformative career launchpad. While at CCNorthBay, Cesar didn't just earn his high school diploma; he built a critical foundation for his future by earning industry-recognized certifications like OSHA-10, HAZWOPER 40, and Forklift Operation. Today, he’s a Landscape Restoration Technician at Prunuske Chatham. This is the power of the Local Corps model: academic success combined with hands-on training builds a stronger California.

The final stage of the Colgan Creek restoration project in southwest Santa Rosa was constructed this past summer. This one has been great to watch, PCI Ecological helped the city envision the concept plans for the entire reach in 2001/ 2002 with input from Elsie Allen High School students. PCI developed 100% construction plans with the city for the final Phase 3 design and provided construction oversight support to wrap up the project in 2025. We look forward to seeing the project mature overtime with Laguna Foundation riparian plantings being installed this winter.

The project, in the works for years and envisioned more than two decades ago, adds open space for an underserved part of the city and improves habitat on what was a degraded section of waterway.

Happy Holidays and Happy New Year!!🥳 We hope you're enjoying the holidays as much as we are! Thank you to our team here ...

’Twas the Night Before Restoration

’Twas the night before winter, all through Scott Valley wide,
Not a channel was dry, not a floodplain denied.
The data loggers were hung by the riffles with care,
In hopes that high flows soon would be there.

The salmon lay tucked in the gravels below,
While beavers dreamed big where the slow waters go.
And staff in their Carhartts, boots muddy and worn,
Had just wrapped a day that began before morn.

When out on the river there arose such a sound,
I sprang from my desk to look all around.
Away to the window I hurried with haste,
Past maps, grants, and plans that were spread and displaced.

The moon on the meadow, the snow on the hill,
Lit BDAs holding the valley so still.
When what to my wondering eyes should appear,
But a watershed healing, year after year.

With crews so dedicated, adaptive, and keen,
I knew in a moment—it must be SRWC’s team.
More rapid than runoff their projects they came,
And they called out the creeks as they spoke them by name:

“Now Sugar! Now French Creek! Patterson, too!
East Fork and Noyes—there’s more work to do!
Reconnect those floodplains! Let groundwater rise!
Build habitat strong for the young salmon fry!”

Like leaves that before a good prescribed burn fly,
They planned with intention and science held high.
So up through the watershed their efforts they threw,
From forests to meadows to tailings once blue.

And then, in a moment, I heard by the door,
The boots of collaboration and partners galore.
As I turned from my thoughts and was spinning around,
In walked community, science, and boots on the ground.

They spoke not a word, but went straight to their work,
Monitoring flows and adapting each quirk.
And filling the valley with hope, not just charts,
They showed how restoration begins in our hearts.

Then I heard them exclaim, as they headed from sight,
“Healthy rivers for all—and to all a good night!”

PCI’s design team created this Story Map to present the Habitat Enhancement Plan for the Gualala River Estuary Habitat Enhancement Project. The project is part of a habitat restoration planning and design project managed by Redwood Coast Land Conservancy (RCLC) in partnership with Sonoma County Regional Parks (SCRP), with funding by the California Department of Fish and Wildlife Fisheries Restoration Grant Program (FRGP). Using Esri's ArcGIS Online Story Map tool, our team designed this comprehensive review of how salmon utilize estuaries, the historic use and impacts in the Gualala River Estuary, current conditions, and actions that can be taken to restore critical habitats and facilitate salmon recovery. This document will serve as a guide to project stakeholders and provide transparency to the public by describing overall restoration methods and typical approaches as well as project specific goals and objectives. Click the link to explore videos, maps, graphics, designs, and aerial photographs (created by PCI) alongside historic photographs (provided by Historical Society of Mendocino County) and satellite imagery that tell the story of the estuary through time. From the historic logging and milling to the salmon life cycle and relationship to hydrological conditions, and the function of engineering restoration methods, this map employs unique visualization techniques to present complex findings in a simple, digestible format.
