Lawrence joined SFEI in 2015 as a Geospatial Software Engineer for the Environmental Informatics team. He received his Bachelor's at UC Santa Barbara and master’s at Oregon State University, both in geography with emphases in geographic information systems (GIS) and remote sensing. Previously he worked on deepwater and offshore oil spill modeling for the US Department of Energy. He has experience in spatial analysis, numerical modeling, web-GIS and web-mapping, web and graphic design, remote sensing, cartography, GIS-programming, and data visualization.

At SFEI, Lawrence provides expertise in geospatial applications, both for GIS and web-application development. He has served as technical lead for a number of web applications and GIS tools for a variety of applications including fish contaminant data, satellite detection of harmful algal blooms, and microplastic pollution.

Big updates from Hidden Nature SF, including new interactive content! (News)

Hidden Nature SF seeks to uncover the natural history of San Francisco’s past landscape. At the heart of the project is the field of historical ecology, which uses interdisciplinary science and visualization techniques to synthesize historical archival data into a completely new perspective on the familiar city. Drawing on hundreds of old maps, photographs, and textual documents, we are reconstructing and mapping the ecosystems and waterways that existed in San Francisco prior to Spanish colonization.

Santa Clara Valley Water District Priority D5 Project's Watershed Condition Assessments (2010 to present) (Project)

https://www.valleywater.org/project-updates/2012-d5-ecological-data-collection-and-analysisSFEI and the Santa Clara Valley Water District's (Valley Water) Priority D-5 Project have been conducting baseline ecological condition assessments in Santa Clara County, CA to characterize the distribution and abundance of stream and wetlands in five major watersheds, and to assess the overall ecological conditions of streams in the watersheds based on the California Rapic Assessment Method for streams (CRAM).  The surveys employ the state's recommended Wetland and Riparian Area Monitoring Plan's watershed aproach that includes the use of GIS-base maps of aquatice resources (BAARI), and spatially-balanced ambient stream condition surveys using CRAM.

GreenPlan-IT Phase II nears completion (News)

SFEI has completed development of Phase II of our GreenPlan-IT application -- a toolset to empower municipalities to plan, assess, track, and report their green infrastructure investments. This helps restore the water cycle and improve filtration of water quality contaminants. In the latest round of implementation work, we collaborated with the cities of Richmond, Oakland, Sunnyvale, and the county of Contra Costa to meet their green infrastructure planning and reporting needs, while also providing needed enhancements to the toolset in response to user feedback.

Next Generation Urban Greening (Project)

SFEI is working with partners across the Bay Area to design tools to help cities achieve biodiversity, stormwater, and climate benefits through multifunctional green infrastructure.

EcoAtlas (Project)

EcoAtlas is a set of tools for generating, assembling, storing, visualizing, sharing, and reporting environmental data and information.

Coastal Wetlands, Beaches and Watersheds Inventory (Project)

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 toward multiple OPC strategic targets, and to more generally summarize information about the current distribution, abundance, diversity, and condition of sur

Coordinated Mapping: How various efforts can work together (News)

SFEI is coordinating the mapping for two inventories of surface waters, wetlands and other aquatic resources in the Sacramento-San Joaquin Delta and along California’s coast. Both efforts will apply the California Aquatic Resource Inventory (CARI) standardized mapping methods and the final map will be integrated into EcoAtlas and made publicly available.

Coyote Creek Native Ecosystem Enhancement Tool (Project)

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.

RipZET: A GIS-based Tool for Estimating Riparian Zones (Project)

The Riparian Zone Estimator Tool (RipZET) is a decision support tool developed by the San Francisco Estuary Institute and Aquatic Science Center for the California Riparian Habitat Joint Venture and the California Water Resources Control Board to assist in the visualization and characterization of riparian areas in the watershed context.

Visualizing and Sharing Intensive Data Assessments (Project)

With California's drought rapidly changing the outlook for natural resources, decision-makers must be equipped with information and tools that facilitate clear and rapid decisions. The proposed grant would fund the standardization, visualization, and sharing of Level 3 data. 

Adapting to Rising Tides: East Contra Costa Shoreline Flood Explorer (Project)

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.

 

Adapting to Rising Tides: Bay Shoreline Flood Explorer (Project)

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.

New Interactive Map Helps Delta Governments and Communities Plan for Adaptation by Understanding Flood Risks from Rising Sea Level and Storms (News)

The Adapting to Rising Tides program of the SF Bay Conservation & Development Commission (ART BCDC), Delta Stewardship Council (DSC) and the San Francisco Estuary Institute / Aquatic Science Center (SFEI) are unveiling the East Contra Costa Shoreline Flood Explorer. SFEI developed the new explorer as a complementary tool to the Bay Shoreline Flood Explorer to allow government organizations and communities in East Contra Costa County to access interactive online maps of local flood risks due to rising sea levels and storm events. These tools help to both highlight what our region could look like without intervention, and to encourage local and regional adaptive plans to minimize flood risks.

Safe to Eat Portal (Project)

Fish and shellfish are nutritious and good for you to eat. But some fish and shellfish may take in toxic chemicals from the water they live in and the food they eat. Some of these chemicals build up in the fish and shellfish - and in the humans that eat fish and shellfish - over time. Although the chemical levels are usually low, it is a good idea to learn about advisories and monitoring in water bodies where you fish, and for fish or shellfish you eat.

Project Tracker assists with regional reporting (News)

More and more groups rely on Project Tracker to assist with their reporting. Why? Because Project Tracker standardizes project data across programs so it is easier to summarize information for reporting purposes. Especially in the Bay Area, it is the most comprehensive regional dataset for project information.
