GIS POD Report

Los Angeles County Department of Public Health POD Project

The L.A. County DPH contracted Willdan to evaluate and plan more than 100 sites as Point of Dispensing facilities to mass-distribute vaccines and medications during a public health emergency. Willdan Engineering and Willdan Homeland Solutions teamed to provide the needed expertise in security, building inspection, analysis and mapping.

Willdan’s GIS team provided site plans, floor plans, parking capacity analysis, ingress and egress maps, and traffic control analysis and mapping. GIS was used to analyze access to public transit, map locations of interior and exterior security posts, locate secure facilities for storage of medical supplies, and to produce a variety of other planning resources for emergency responders.
