Coyote Creek Watershed Reassessment 2020: 10-Year Reassessment of the Ecological Condition of Streams Applying the California Rapid Assessment Method, Santa Clara County, California. SFEI Contribution No. 1043. San Francisco Estuary Institute: Richmond. CA. p 131.2021.
This report describes the amount and distribution of aquatic resources in the Coyote Creek watershed, Santa Clara County, California, and presents the first reassessment of stream ecosystem conditions using a watershed approach and the California Rapid Assessment Method (CRAM). Field work was conducted in 2020, ten years after the baseline watershed assessment completed in 2010.
Towards a Coarse Sediment Strategy for the Bay Area. SFEI Contribution No. 1032. San Francisco Estuary Institute: Richmond, CA.2021.
Historic and current regional management of watersheds and channels for water supply and flood control across the San Francisco Bay Area has cut off much of the coarse sediment that was historically delivered to the Bay. Here we define coarse sediment as having grain sizes larger than 0.0625 mm, which includes sand, gravel and even cobble, as opposed to fine sediment that includes clay, mud and silt. Future projections indicate that sediment supply will not meet the demand from extant and restored tidal marshes to keep up with sea level rise.
The US EPA Water Quality Improvement Fund Preparing for the Storm grant has funded the Zone 7 Water Agency, the San Francisco Estuary Institute and the San Francisco Bay Joint Venture to support the future development of a successful regional coarse sediment reuse strategy. Development of such a strategy requires an understanding of logistical and regulatory hurdles and identification of key strategies for breaking down barriers. One potential solution for meeting the sediment demand along the Bay margin is to utilize coarse sediment that is removed from flood control channels by public agencies. To-date, very little of this sediment that is removed is beneficially reused for restoration along the Bay shoreline. The current economic and regulatory framework around sediment removal presents many challenges, barriers and lack of incentives for agencies to reuse their sediment.
This document represents a step forward towards beneficially reusing coarse flood control channel sediment by outlining reuse challenges, and identifying incentives for participation and potential solutions.

Santa Clara County Five Watersheds Assessment: A Synthesis of Ecological Data Collection and Analysis Conducted by Valley Water. . SFEI Contribution No. 963. San Francisco Estuary Institute: Richmond. CA. p 71.2020.
This report synthesizes the baseline assessments for Santa Clara County’s five watersheds to present similarities, differences, and compare ecological condition in streams across watersheds and their subregions, San Francisco Bay-Delta ecoregion, and statewide based on CRAM. It also interprets the assessment results and comparisons to identify risks to stream conditions, and opportunities for stream stewardship. Project D5’s baseline assessments establish a monitoring and assessment framework for evaluating the performance of Valley Water’s programs, projects, maintenance activities, and on-the-ground stewardship actions.
Summary of Water Year 2017 precipitation, discharge, and sediment conditions at selected locations in Arroyo de la Laguna watershed, with a focus on Arroyo Mocho. SFEI Contribution No. 912. San Francisco Estuary Institute: Richmond, CA.2020.
This report summarizes the precipitation, discharge, and sediment conditions observed from October 1, 2016 to September 30th, 2017 (Water Year (WY) 2017) in the Arroyo de la Laguna watershed, with a focus on the Arroyo Mocho watershed. This information was collected by the Zone 7 Water Agency to support operation and maintenance of their flood control facilities. Additionally, this and similar information collected in WY 2018 and 2019 will be utilized to update the Arroyo Mocho watershed sediment budget (Pearce et al, 2020).
Wildlife Habitat and Water Quality Enhancement Opportunities at Castlewood Country Club. SFEI Contribution No. 1003. San Francisco Estuary Institute: Richmond, CA.2020.
Meeting human and ecological needs within San Francisco Bay’s watersheds is increasingly challenged by flooding, water quality degradation, and habitat loss, exacerbated by intensified urbanization and climate change. Addressing these challenges requires implementing multi-benefit strategies through new partnerships and increased coordination across the region’s diverse landscapes. Actions to improve water quality and enhance habitat for biodiversity in our highly developed and managed landscapes can help the region as a whole to build resilience to withstand current pressures and future change. The EPA-funded project, “Preparing for the Storm,” aims to address these challenges at the site- and landscape-scale through studies and implementation projects in the Livermore-Amador Valley. As part of this larger project, this technical report presents a synthesis of water quality and habitat improvement opportunities for a golf course of Castlewood Country Club.

Changing Channels: Regional Information for Developing Multi-benefit Flood Control Channels at the Bay Interface. Flood Control 2.0. SFEI Contribution No. 801. San Francisco Estuary Institute: Richmond, CA.2017.
Over the past 200 years, many of the channels that drain to San Francisco Bay have been modified for land reclamation and flood management. The local agencies that oversee these channels are seeking new management approaches that provide multiple benefits and promote landscape resilience. This includes channel redesign to improve natural sediment transport to downstream bayland habitats and beneficial re-use of dredged sediment for building and sustaining baylands as sea level continues to rise under a changing climate. Flood Control 2.0 is a regional project that was created to help develop innovative approaches for integrating habitat improvement and resilience into flood risk management at the Bay interface. Through a series of technical, economic, and regulatory analyses, the project addresses some of the major elements associated with multi-benefit channel design and management at the Bay interface and provides critical information that can be used by the management and restoration communities to develop long-term solutions that benefit people and wildlife.
This Flood Control 2.0 report provides a regional analysis of morphologic change and sediment dynamics in flood control channels at the Bay interface, and multi-benefit management concepts aimed at bringing habitat restoration into flood risk management. The findings presented here are built on a synthesis of historical and contemporary data that included input from Flood Control 2.0 project scientists, project partners, and science advisors. The results and recommendations, summarized below, will help operationalize many of the recommendations put forth in the Baylands Ecosystem Habitat Goals Science Update (Goals Project 2015) and support better alignment of management and restoration communities on multi-benefit bayland management approaches.
Demonstration of a Watershed Approach to Wetland Restoration Planning for Load Reductions: A Pilot Demonstration Project Using GreenPlan-IT in the Santa Rosa Plain, Sonoma County, California. SFEI Contribution No. 996. San Francisco Estuary Institute: Richmond. CA.. 2017.
This summary memorandum presents technical recommendations to the 401 Certification and Waste Discharge Program (401 Program) of the State Water Resources Control Board (State Board) for a coherent, scientifically sound, repeatable, watershed approach to wetland restoration site evaluation, compliance monitoring and assessment, and Tracking. The recommendations are drawn from the previous four memoranda produced for the Pilot Demonstration Project (Project) that address the following subjects: project work plan and information flow diagram; scientific literature review; landscape scenario planning (to map and prioritize restoration opportunities); and a framework for a watershed-approach to evaluate and report the capacity of a wetland restoration site to protect wetland beneficial uses.
This Project focused on a sub-watershed of the Santa Rosa Plain, in Sonoma County, California. The area was chosen for the Project for three reasons: (1) it is integral to an existing nutrient TMDL and therefore is supported relatively well with hydrological and nutrient data; (2) the historical and existing wetlands and streams of the area were mapped recently in sufficient detail to inform landscape planning; and (3) implementation of the TMDL will involve wetland restoration to reduce downstream nutrient loads, and therefore the Project may help implement the TMDL.
The primary overall purpose of this Project was to explore how numerical simulation and statistical modeling could be combined with existing wetland assessment and reporting tools to create a coherent, watershed-based approach to wetland beneficial use protection. Any relevance to the existing nutrient TMDL for the demonstration area is an intentional, but secondary benefit of this Project.
