Coverage analysis
What 5 minutes on foot covers in Salt Lake City.
North-south I-15 spine with a hard eastern mountain wall compresses isochrones into elongated north-south ovals unique among western metros.
At 5 minutes on foot, the Salt Lake City walk-time isochrone captures the immediate pedestrian footprint — the area where pedestrian customers make routine, repeat visits without any deliberate trip planning — the true walkshed of impulse and convenience. Unlike a simple ≈ 400 m radius circle, the real pedestrian-network polygon follows Salt Lake City's actual street grid, accounts for crossings, parks, and dedicated walk paths, and contracts sharply around freeways, rail corridors, and waterways that break pedestrian continuity.
Walk-shed area at 5 minutes: ≈ 0.2–0.4 km² in a standard urban grid. The 5-minute isochrone is the standard input for pedestrian trade-area analysis, walkability scoring, and proximity-retail siting.
The city-level population of 213,000 and a median household income of $68,000 give a sense of Salt Lake City's density, but the figure that matters for walkable-retail siting is the population inside the pedestrian polygon — not the city as a whole. That number shifts dramatically depending on whether you're anchored in a high-density urban core or a lower-density neighbourhood where blocks are long and crossings are scarce. Use the tool above to set your actual candidate address, then generate the isochrone to see the real walk shed.
