Redford Conservancy Map of Warehouse Growth Puts a New Lens on the Inland Empire

Estimated Warehouse Distribution in San Bernardino and Riverside Counties
Based on County data and includes areas of the county not pictured above. All numbers should be considered an estimate. Map by Graham Brady ’21. With thanks to Lani Fox. The first published iteration of this analysis used warehouse as the sole keyword with which to subselect the polygons. Future versions will use revised keywords that more aptly select known warehouses from the datasets. This analysis is ongoing and relies on dynamic data that are updated periodically. We recognize how publishing workflows improves transparency in methods. Revisions to this workflow to increase accuracy and robustness of the analysis are welcomed. Some of our goals include an interactive widget to view warehouse parcels alongside satellite imagery and through time; we will update this page as necessary.

As featured in the Los Angeles Times, the Redford Conservancy has released an animated map of warehouse growth in San Bernardino and Riverside Counties from 1975-2021.

For years, scholars, activists, and advocates have referenced the now infamous cluster of warehouses in the Inland Empire as having square footage in the millions. Over a year in the making, the new map released by the Redford Conservancy demonstrates an alarming new high: Warehouses now total over a billion square feet. And counting. How did we get our data? Click here.

The first published iteration of our analysis used “warehouse” as the sole keyword with which to search for warehouses. Our most current version of the 2021 map of Riverside County will use revised keywords that more aptly select known warehouses from the datasets. Counties sometimes list warehouse parcels as “industrial,” which makes data analysis regarding the number and square footage of warehouses challenging. Ground truthing has revealed a problem that’s even more massive in scope and our new maps will include select industrial parcel data to reflect an even more accurate and saturated warehouse landscape in the Inland Empire. Stay tuned!!

We are working with Radical Research to create an interactive map that is designed for community members and municipalities to use for information gathering and advocacy. Stay tuned!

One billion square feet is over 37 miles of pure warehouse–concrete, steel, rooftop, and pavement. The Inland region has the worst air quality in the United States as a result of diesel truck and train traffic. Residents who live near warehouses face chronic health problems, such as intergenerational asthma, reproductive issues, and cancer. The industry is also heavily reliant on temporary labor models rife with health and safety issues and wage theft. Numerous reports demonstrate how the presence of warehouses in communities cements poverty. The scope of warehouse construction also has crippling consequences for biodiversity, greenhouse gas emissions, and water filtration. This is what is called the “Diesel Death Zone.”

Our map is a tool for organizers, planners, and elected officials to aid in land use decision-making. If you would like data on warehouse growth associated with your city or neighborhood, or for more information about our method of obtaining and analyzing warehouse data, please contact us.
