PCI congratulates Lauren Hammack on winning Restorationist of the Year at the 40th Annual Salmonid Restoration Federation (SRF) Conference! SRF first presented the award in 1992 to Bill Eastwood, co-director of the Eel River Salmon Restoration Project, to honor grassroots salmonid habitat restorationists. Since 1998 SRF has honored a restorationist each year with a roast, a toast and a brass sculpture created by sculptor Dick Crane. The title reflects Lauren’s tireless work dedicated to the recovery of salmonid habitat, specifically her geomorphology design and construction work along the Ten Mile River and throughout the Garcia River estuary in recent years. Way to go Lauren! (Scroll to see more photos of Lauren’s award and other PCI shenanigans at the 2023 SRF conference. Note: All PCI-purchased swim noodles used for the skit pictured in the last photo were donated to the Sebastopol Ives Swim Pool Summer Learn-to-Swim program).

PCI Civil Engineer Jasper Rice-Herdt documenting bank erosion along Lakeville Creek on Sonoma Land Trust property, as part of restoration planning for the site. The Lakeville Creek Restoration Project is one of the first projects in the state to utilize the new Statutory Exemption for Restoration Projects (SERP).
Ecological restoration is an essential tool in addressing urgent concerns across California, including reducing carbon in the atmosphere and protecting residents from the impacts of climate change. But regulatory compliance requirements can be significant hurdles that slow the pace of restoration. The State of California has recognized this issue and is working to streamline the regulatory process for strategic, science-based restoration projects. Two projects on which PCI has collaborated are utilizing new regulatory compliance tools developed by the State’s Cutting the Green Tape Team. In fact, these two projects — The Nature Conservancy’s Garcia River Estuary Enhancement Project and the Sonoma Land Trust’s Lakeville Creek Restoration Project — are the first two Statutory Exemption for Restoration Projects (SERP) approvals in the State. Both projects are highlighted in a recent article from San Francisco Estuary Magazine and on the CDFW Statutory Exemption for Restoration Projects (SERP) website. Read the article here, and visit CDFW’s SERP informational page, here.
In September of 2021, Governor Newsom signed Senate Bill 155, which provided a new California Environmental Quality Act (CEQA) statutory exemption for restoration projects. PCI, along with partners at the Nature Conservancy (TNC) and the North Coast Regional Water Quality Control Board, was instrumental in working with CDFW’s Cutting the Green Tape Team to develop the first statewide habitat restoration statutory exemption for the Garcia River Project. That project will increase the extent and value of in-channel and floodplain habitat for salmonids within the Garcia River estuary in coastal Mendocino County.
The Lakeville project in southern Sonoma County, pictured above, will restore ecological form and function that was lost from an alluvial valley due to channel incision, wetland draining, and decades of intensive grazing. The overarching project goal is to create a functioning coastal alluvial fan ecosystem that more closely resembles historic conditions, is self-sustaining, and is more resilient to climate change. The project will provide more diverse plant and wildlife habitat, allow for greater infiltration and storage of water, and increase the likelihood of sustaining wetlands into the future.
Last month, the State Water Resources Control Board adopted a General Order and Programmatic Environmental Impact Report (PEIR) that will help PCI and our partners streamline permitting and implementation for important habitat restoration projects.
Salmonid habitat restoration projects similar to PCI’s work for the SF Zen Center, shown here, will be easier to implement with the new General Order.
The State Water Board adopted the General Order and certified the PEIR for Restoration Projects Statewide on August 16.
Previously, the State Water Board issued a general Water Quality Certification for small habitat restoration projects. Projects could only qualify if they did not exceed five acres or a cumulative total of 500 linear feet of stream bank or coastline. Larger restoration projects often had to obtain individual water quality certifications and/or waste discharge requirements, and securing individual authorization was time-consuming and increased the cost of regulatory compliance.
The adoption of the new General Order and accompanying PEIR was eagerly anticipated according to PCI Principal Environmental Planner/Project Manager Carrie Lukacic.
“The General Order not only makes it easier and less cumbersome to secure a permit from the Regional Water Board, it may provide CEQA compliance for restoration projects,” she says. “We are excited to work with our local folks at the Regional Water Board and look forward to introducing the use of available permitting efficiencies to others not as familiar with the use of the tools available for permitting restoration activities. We now have a method to permit both large- and small-scale restoration, which should help increase the pace and scale of critical habitat improvement needs.”
The General Order will provide coverage for the following kinds of restoration projects: -Improvements to Stream Crossings and Fish Passage -Removal of Small Dams, Tide Gates, Flood Gates, and Legacy Structures -Bioengineered Bank Stabilization -Restoration and Enhancement of Off-Channel and Side-Channel Habitat -Water Conservation Projects -Floodplain Restoration -Removal or Remediation of Pilings and Other In-Water Structures -Removal of Nonnative Terrestrial and Aquatic Invasive Species and Revegetation with Native Plants -Establishment, Restoration, and Enhancement of Tidal, Subtidal, and Freshwater Wetlands -Establishment, Restoration, and Enhancement of Stream and Riparian Habitat -Upslope Watershed Sites

Before/After is a series where we highlight the long-lasting impact of our restoration work.
Instream elements that PCI installed with Proven Management shortly after construction.
Vigorous willow growth and a notable uptick in wildlife recently covered by the Napa Valley Register are two indicators that Napa Creek – a project PCI worked on in 2013 – is becoming the revitalized, healthy waterway that project engineers envisioned two decades ago.
PCI was hired to work with Proven Management to assist with instream elements of the project, under Proven Management’s contract with the U.S. Army Corps of Engineers. PCI worked with Proven Management to install rock rootwad revetment structures, bank log pockets, log barbs and rock V-weirs throughout the creek in downtown Napa.
Construction underway after dewatering.

The City of Napa has historically been prone to destructive and deadly flooding events. According to FEMA, a total of 19 floods caused more than $542 million in residential property damage between 1961 and 1997; that total doesn’t include economic losses in the tourism industry, environmental damage, or loss of life. The Napa River/Napa Creek Flood Protection Project was voted into reality by the passage of Napa County Measure A in 1998. The half-cent local sales tax levy provided a funding mechanism for the local share of the project cost and funded flood protection, drainage improvements, dam safety, and watershed management projects, and helped to strengthen a partnership with the U.S. Army Corps of Engineers. Project engineers envisioned a healthy waterway as the centerpiece of Napa; PCI’s work in 2013 helped to make that vision a reality.
Fast-forward ten years, and the project area is thriving. PCI Principal Engineer Lucas Walton recently visited the site and observed that while the weirs haven’t changed, the rootwad revetment is no longer visible because the willows have grown so vigorously
“It is pretty amazing to see how the site has changed and how the local ecology is thriving as a result of the project,” he says.
See the before/after images, below.

Welcome to Before/After, a series where we showcase the long-lasting impact of our restoration work.
In 2017, the Sonoma County Agricultural Preservation and Open Space District (Ag + Open Space) proposed a riparian restoration project on its 76-acre Oken property. The property is located on Petaluma Hill Road, along the northeastern edge of Rohnert Park in Sonoma County. The grassland supports grazing and acts as a bowl for several drainages running down from the surrounding hills. Erosion wasn’t historically a problem, but housing development, the routing of a small stream through roadway culverts and open grazing of the tributaries in recent years had combined to channelize the waterways that cut across the property, creating several steep head cuts.
Before, with active headcuts and erosion
PCI’s biology, design, engineering and planning teams worked together to prepare a plan that would restore the waterways. Their collective vision involved bioengineered repairs, rock grade control, an arch culvert livestock crossing, wildlife firefly fencing and an abundance of willows.
Before urbanization, intermittent tributaries like the ones at Oken would have formed a series of distributary channels that would fan out as they exited the foothills, storing sediment and recharging groundwater. Despite the erosion, an alluvial fan still existed on the property, but it was incised with particularly prominent headcuts. Designers envisioned a willow “sausal” transition for this area (sausal means willow in Spanish, and refers to a thick willow grove). The eroding bank would be re-contoured with soil fill and the disturbed area would be covered with coir blanket and coir mat over native grass seed. A willow thicket would stabilize the slope and allow flows to continue fanning out through use of a bioengineering technique using living willow brush sills and wattles before draining into the main channel. Willow poles would be planted to create the thicket above the sills. At the toe of the slope, along the main channel, two brush sills would be placed with willow wattle anchors.
Willow sausal after construction
PCI’s design plans also called for the construction of three rock stabilization structures. A drop inlet at the downstream end of the swale in the southwestern corner of the property would be protected with a rock basin. Headcuts in the southern end of the property and in main channel toward the center of the property would be repaired. An incised channel segment upstream in the main drainage would be restored with soil fill to create a stable channel bed.
Willow sausal in May 2022
As part of the design process, PCI looked at potential opportunities for additional habitat enhancement, and provided recommendations for wildlife-friendly grazing infrastructure and management of invasive plant infestations.
Construction was completed in 2021; Hanford ARC was the contractor, and PCI’s planning team secured all necessary permits. About 1,000 plugs of native rush and sedge were planted along the newly fenced out creeks by Students and Teachers Restoring a Watershed (STRAW), a program of Point Blue Conservation Science that brings ecological education and opportunities to participate in restoration to local schools.
Willows planted as part of the sausal restoration will be assessed each year for five years after planting. In summer, survivorship and growth of willow plantings will be recorded and general observations of plant health noted. In May of 2022, the sausal area appeared lush and green, and the stabilized waterway showed no signs of erosion.
PCI’s construction crew continues to care for the property by removing invasive thistle, mowing firebreaks, and weedeating around the plantings. When crew members arrived on-site in May of this year, the property’s inhabitants — and original weedeaters — insisted on checking out their equipment.

We will be in good company this week at the 2022 Salmonid Restoration Conference in beautiful Santa Cruz.
PCI Principal Civil Engineer Luke Walton will be presenting Tuesday at a workshop on Restoration Approaches to Instream Large Wood Augmentation along with our colleagues at Trout Unlimited, Pacific Watershed Associates, the California Department of Fish and Wildlife, and others. Principal Hydrologist Christopher Woltemade will be presenting Friday at 10:30am on High-Resolution Water Budget Hydrology to Support Collaborative Water Management for Salmonid Recovery in the Mill Creek Watershed and Navarro River.
The theme of this year’s conference is Reconnecting with Resilience, and its central coast location is important to that theme.
“Santa Cruz is home to some of the southernmost populations of wild salmonids left in California,” the Agenda Packet states. “The conference will highlight lagoons, seascape ecology, ocean conditions, life history variation, and feature tracks on drought, climate, and hydrology; and another on physical habitat conditions and food webs.”
In September 2021, Governor Newsom signed Senate Bill 155 which provided a new California Environmental Quality Act (CEQA) statutory exemption for restoration projects. PCI, along with partners at the Nature Conservancy (TNC) and the North Coast Regional Water Quality Control Board, was instrumental in working with California Department of Fish and Wildlife’s Cutting the Green Tape Team to develop the first statewide habitat restoration statutory exemption–for the Lower Garcia River Estuary Salmonid Habitat Enhancement Project.
In the words of Peter van de Burgt, the North Coast Restoration Project Manager for TNC, and PCI alum: “This statutory exemption could not have come at a better time for the Garcia project, and it’s really exciting to have the opportunity to immediately put it into practice. I’m optimistic that the exemption will be an invaluable tool for implementing ambitious restoration projects in a more time- and cost-efficient manner than ever before, which is exactly what we need given the enormity of the challenges we face.”
The Lower Garcia River in coastal Mendocino County is important steelhead and coho salmon habitat. However, winter rearing and outmigration habitat in the estuary is limited due to a history of channelization and simplification for agricultural use, excessive sedimentation from upper watershed land use, and large woody debris clearing. The enhancement project is designed to increase in-channel and floodplain habitat through the middle estuary and expand access to the newly created habitat for salmonids during their most critical life stages. PCI has provided site assessment, design, planning, and regulatory compliance services to TNC for the project.
Our team worked hard to make this use of the new pathway possible, and we’re delighted to be part of the statewide effort to reduce hurdles for large-scale restoration work! PCI is proud to be part of a community that is committed to increasing the scale and pace of salmonid restoration across California.
