How Potrero ranks

Percentiles among 3,000 random land points in each region, scored the same way: land in general, not beekeepers' apiaries.

About 86% of the land here is scored with national averages for its vegetation type rather than measured plant cover, so the wild-plant part of this estimate is rougher than the crop part.

An estimate from public maps (USDA crop maps 2021–2025 averaged, LANDFIRE vegetation), not a survey of the ground. Maps can't see garden plantings, understory density, other beekeepers' hives, or this year's weather. The point is the Census Bureau's published center of Potrero (32.6131, -116.6068); a yard a mile or two away can differ, so check your own spot. The FEMA flood map was not checked for this page.
