Lakeville Creek Restoration – Construction Phase Complete

A deeply incised, eroding channel on Sonoma Land Trust’s Sears Point Ranch Preserve and the adjacent Sonoma Raceway property has been restored, marking the completion of the earthwork phase of the innovative Lakeville Creek project, and setting the stage for the next step:  planting the site with over 30,000 native wetland and wet meadow plants.

A new video from SLT features PCI Civil Engineer Lucas Walton explaining part of the earthwork process for the project, which included moving roughly 9000 cubic yards (or about 900 dump truck loads) of soil. Watch the video below!

PCI has been working with Sonoma Land Trust (SLT) since 2020 to design and plan this restoration effort. The goal of the project is to restore a degraded coastal grassland valley and alluvial fan back to its historic wet meadow complex condition by filling the channel. The site is on the northwestern edge of San Pablo Bay, just above the historic bay margin, and extends 4,200 feet up from Lakeville Highway. This restoration approach – known as “Stage Zero” – has returned the valley to its original grade (or close to it), and provided the conditions for natural establishment of a branching network of shallow channels, wetlands, and wet meadow.

California Department of Fish and Wildlife (CDFW) provided funding for the design, planning and the construction efforts. During the planning phase of the project, PCI completed biological evaluations, developed the design, secured ecological permits from numerous agencies, and helped SLT apply for grant funding. Construction was provided by Dixon Marine Services. Sonoma County served as lead agency to complete a Statutory Exemption for Restoration Projects to comply with the California Environmental Quality Act. Many other partners have also contributed to this effort.
