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.
