As municipalities and water-quality regulatory agencies have implemented programs and policies to improve management of the trash loading to storm drain conveyances, there has been increased interest in using a common set of methods to quantify the effectiveness of management actions. To create a foundation for developing a consistent, standardized approach to trash monitoring statewide, the project team performed a method comparison analysis, based on two seasons of fieldwork. This analysis facilitated the assessment of the accuracy, repeatability, and efficiency of some already developed trash monitoring methodologies already in use, as well as help to investigate a new, innovative method (cf. Fielding Testing Report on trashmonitoring.org). Methods developed by the Bay Area Stormwater Management Agencies Association (BASMAA) for use in the San Francisco Bay Area were compared to methods developed by the Southern California Stormwater Monitoring Coalition (SMC) for use in coastal southern California. One of the chief goals of these comparisons was to understand the similarities and differences between the already existing methods for detecting, quantifying, and characterizing trash in selected environments. Readers will find that the data bear out remarkable levels of accuracy and precision with quantitative metrics that help to align methods and management concerns. Furthermore, the degree of correlation among tested methods were especially high, offering greater opportunities for inter-method comparisons.
The findings of this project are intended for use by public agencies, non-profit organizations, private consultants, and all of their various partners in informing a statewide effort to adopt rigorous, standardized monitoring methods to support the State Water Board’s Trash Amendments. Over the next couple of decades, such public mandates will require all water bodies in California to achieve water quality objectives for trash.
The Ocean Protection Council (OPC) and SFEI will develop an inventory of the wetlands and other surface waters of all California’s coastal HUC-8 watersheds, including the inland Delta of the San Francisco Estuary, to help implement the OPC’s 2020-2025 Strategic Plan. The inventory will include a dashboard and other online tools that enable the OPC and the public to track progress towards multiple O
The Coyote Creek Native Ecosystem Enhancement Tool (CCNEET, neet. ecoatlas.org) is an online decision-support tool to identify opportunities to improve ecological conditions. CCNEET was inspired by the need for a watershed approach to environmental resource management. Available ecological and environmental information is synthesized by objectives, management questions, and enhancement actions to identify and justify potential habitat improvements along the creek corridor. The overarching goal of CCNEET is to help coordinate habitat conservation and enhancement along so that multiple projects and limited funding can result in meaningful ecological improvement.
Smoking has long been known to lead to tobacco-related diseases and harmful health outcomes, including heightened risk of cancer, stroke, and heart disease. Not only is tobacco harmful to individual health outcomes, but it also harmful to the environment. Cigarette butts are the most common form of litter and an estimated 4.5 trillion butts are improperly discarded every year worldwide. Cigarette butts contain at least 4,000 chemicals, and about 50 of these are carcinogenic.
The response of shallow groundwater to sea-level rise is a relatively new field of study. For low-lying coastal communities, sea-level rise adaptation efforts must consider the potential for groundwater rise to avoid maladaptation. The need to better understand this slow and chronic threat was identified as a critical data gap in the San Francisco Bay Area’s adaptation efforts during the Bay Area Groundwater and Sea-Level Rise Workshop in 2019.
SFEI’s Environmental Informatics team has designed and developed the Bay Area Flood Explorer for the Bay Conservation and Development Commission's (BCDC) Adapting to Rising Tides (ART) program. The project is designed to highlight threats posed by sea level rise. The map displays sea-level-rise data created by AECOM, which was developed with support from the Metropolitan Transportation Commission, the Bay Area Toll Authority, and the greenhouse gas reduction funds.
As a continuation of our collaboration with BCDC and the Adapting to Rising Tides (ART) team, the technical team at SFEI has developed a new version of the sea-level rise visualization tool which focuses on East Contra Costa and the Delta. The East Contra Costa Shoreline Flood Explorer incorporates regionally specific data that takes into account inundation and flooding information as a product of riverine flooding and sea-level rise. The map visualizes these data in conjunction with storm events and makes it available to the public, businesses, and policymakers so that they can assess and prepare for potential impacts to communities.
In a partnership with Kinetica, a data analytics start-up, and Oracle, SFEI and SCCWRP leveraged public funding from the California Ocean Protection Council to advance automated trash detection capabilities. The team deployed servers in the @Oracle Cloud to increase performance dynamically. Learn more about this project...
