Coverage analysis
What 30 minutes covers in Erie.
Lake Erie lakefront city where the shoreline eliminates all northward reach and Peach Street south toward Millcreek defines the entire commercial isochrone.
At 30 minutes, the Erie isochrone captures the regional catchment — a zone where trips are planned but customers are willing to cross neighborhood boundaries. Unlike a 100–350 km² circle, the real road-network polygon follows Erie's actual highway corridors, accounts for bridge and interchange chokepoints, and respects the natural and built barriers that force drivers to detour.
Best-fit categories at 30 minutes: Big-box, regional dining, car dealership, furniture, healthcare anchor, sporting goods. The 30-minute isochrone is the standard input for cannibalization studies and multi-unit expansion modeling.
The city-level population of 93,795 and a median household income of $41,300 give a sense of Erie's economic density, but the figure that matters for site selection is the population inside the polygon — not the city as a whole. That number shifts dramatically depending on whether you're drawing from a high-density urban core or a lower-density suburban corridor. Use the tool above to set your actual candidate location, then generate the isochrone to see the real catchment.
