County Health and Human Services


After recent standards enacted by California Department of Health Care Services (DHCS) were announced in early 2018, VESTRA performed Network Adequacy Mapping services and provided training for a number of California counties. This required county health providers to demonstrate accessibility of services for mental health beneficiaries measured by time, distance, and timely access.

The projects involved licensing and installing ArcGIS Pro, Network Analyst extension, and Street Map Premium Extension when necessary. VESTRA then performed the mapping on-site for the counties.

Mapping involved geocoding beneficiary and provider locations, generating heat map views, and generating drive-time and distance buffers using the Network Analyst extension. The projects also included creating documentation and/or providing training for County staff to enable them to repeat the process for ongoing quarterly reporting.

City of Santa Maria, CA


The City of San Maria’s Department of Utilities Water Resources Operation and Maintenance Section was interested in improving their field crews efficiency by making information on disabling/enabling customers water service connections available online. 

Information on the status of the City’s water service connections were being maintained in a legacy system by the City’s Department of Administrative Services.  The City had the capability of querying this system every thirty minutes, extracting address information for needed turn offs/ons, and sending this information to a Microsoft SQL table. 

Per the City's requirements, VESTRA developed an application that geocodes the addresses within this Microsoft SQL table and presents the results in an ArcGIS Online feature service making it available online and via mobile devices. This has enabled field crews the ability to access and edit the information from their smart phones utilizing Esri’s Collector for ArcGIS application.

Livermore Valley Winegrowers Association


Livermore Valley Winegrowers Association (LVMA) contracted with VESTRA to provide services in creating climate maps from the Prism Climate Groups data to assist LVMA with their effort to assess vineyard suitability within the Livermore Valley American Viticulture Area (AVA). The project consisted of migrating 30 years’ worth of climate data from the Prism Climate Group’s website into ArcGIS Online as feature services. Using these services, VESTRA built maps in ArcGIS Online using Web AppBuilder for ArcGIS  to asses such things as annual average precipitation, average mean temperature per month, minimum/maximum temperature per month, and average growing degree days.

M.J. Bradley & Associates (MJB&A)


M.J. Bradley & Associates (MJB&A), an environmental consulting firm based in Washington DC, contracted with VESTRA for help in developing a web application that would show pollution sources and data in the Washington DC area for the Environmental Defense Fund (EDF).    The web application developed by VESTRA overlays a set of power plants and allows users to identify air quality grades and natural lands by visualizing multiple maps and layers within the single web application. 

Formation Environmental / Imperial Irrigation District


Salton Sea air quality program support

Challenge: The Salton Sea Air Quality Mitigation (SS AQM) Program was developed by the Imperial Irrigation District to provide a comprehensive, science-based, and adaptive approach to address air quality mitigation requirements associated with the transfer of conserved water under the Quantification Settlement Agreement. The transfer reduces the volume of agricultural return flow to the Salton Sea, thereby exposing the playa and increasing the potential for dust emissions that could affect nearby communities.

Solution:  VESTRA worked with Formation Environmental to develop an end-user web application that allows users to download GIS layers for comparison and visualization, which includes: Emissions Inventory and Monitoring Program, Dust Control Strategy and Planning, as well as Dust Control Implementation.

The Emissions Inventory and Monitoring Program will identify the playa surface characteristics and surface mineralogy dynamics that create salt crust conditions vulnerable to erosion. It will also measure the emissions potential of playa surfaces and identify dust source areas. These activities will provide a better understanding of salt crust formation and erosion at the Salton Sea, and ultimately inform dust control planning and implementation. The SS AQM Program will also assess dust emissions from adjacent desert areas to better understand the location and timing of off-sea emissions. Visualizations include: Playa Exposure, Playa Surface Characteristics, Playa Emissions Potential, and the Off-Sea Emissions Inventory.

The proactive dust control strategy is designed to prevent exposed playa from becoming a significant source of PM10 emissions, which will help protect the public health of the communities near and around the Salton Sea. A large part of this strategy is to identify and implement dust control measures (DCMs) on emissive playa surfaces before they reach thresholds that prompt regulatory orders for control studies.

Long-term dust control at the Salton Sea is anticipated to include a mosaic of dust control measures to effectively control dust, minimize water use and maximize habitat. Small-scale dust control pilot studies provide important data regarding the suitability of various measures for the playa. Field scale pilot studies provide experience scaling, adapting, and combining dust control measures at a larger scale. A series of field scale pilot studies will be implemented in early 2017 (see below). Planning is underway for several additional field scale pilot studies in 2017-2018.

Benefit: By having all of the data available within an interactive web application, the Imperial Irrigation District is able to visualize the effects of the playa over time and how this is affecting the air quality surrounding the Salton Sea.  The web application gives the ability for users to see the affects over time utilizing a time slider and create a scientific prediction for what could happen in the future.




VESTRA developed the Rural Opportunity Index (ROI) Data Analysis Viewer for the UC Davis CRC.  The purpose of this application was to aid in targeting resources and policies toward people with the greatest need in a community, and also help create communities of opportunity for all Californians.  This web application was based on Esri’s ArcGIS API for JavaScript and has similar functional requirements to the PYOM viewer.

State Water Resources Control Board (SWRCB)

Cannabis Identification and Prioritization System (CIPS)

PROBLEM: The cultivation of Cannabis in rural parts of California has been increasing which has resulted in significant environmental impacts in the watersheds of California; such as, increased pollution in the local, regional, and state water supplies, increased soil erosion, as well as increased nutrient and pesticide laden runoff. California’s extreme drought conditions have further magnified these impacts.

SOLUTION: The SWRCB and the California Department of Fish and Wildlife were tasked with trying to regulate this activity. As a part of this effort, they contracted with VESTRA to design a Cannabis Identification and Prioritization System (CIPS), which acts both as a repository of geospatial information on grow locations and a tool for helping the agencies prioritize their regulatory efforts based on the potential impact individual grows have on water resources, fish, and wildlife.

VESTRA, along with Formation Environmental, worked to capture grow locations and developed raster datasets which include percent slope, length of slope, evapotranspiration and proximity to surface water.  These raster datasets are used along with information on the proximity of threatened fish and wildlife to model the level of threat associated with each grow, allowing the agencies to establish priorities for action.

CIPS APPLICATION: VESTRA was responsible for the design and development of the system.  One of the project requirements was that the system leverages the SWRCB’s existing Esri Enterprise system.  The development effort includes a JavaScript web interface to be used by agency staff tasked with regulating Cannabis cultivation and geoprocessing services that are used to model the environmental threat based on the factors a user wants to consider in their analysis along with the weight they associate with each factor. 

The web interface includes an operations dashboard that summarizes the number of grows that have been identified in the state, whether they’re outdoor or greenhouse grows, the number in each SWRCB region, and the estimated amount of water consumed by each grow.  This dashboard is updated nightly as data becomes available.
