What counts as a Drivable Zone▾

What counts as a DRIVABLE Zone (solid colored tiles) Minimum size: 100K single-family homes in Michigan and Northeast Illinois (Cook, DuPage, Kane, Kendall, Lake, McHenry, Will); 90K in Pennsylvania; 80K in Ohio and Maryland; 60K in the rest of Illinois, Virginia, Iowa and Delaware (Census-counted, dialable homes only). Drive time: measured between the two farthest-apart neighborhoods inside the zone (the red dots), not border to border. Goal 30–60 min. Once a zone meets its minimum it takes in every nearby dialable neighborhood it can, up to 60 min. A rural zone that needs more room to reach its minimum may run longer, but never over 80 min. One county per zone: a big county is split into zones of about equal size. A county too small for a zone of its own is pulled into a neighboring zone, or grouped with other small neighbors. Rare exception: a town cut off from its own county’s zones (e.g. Grosse Pointe, cut off by Detroit) joins the zone next to it. Shape: one connected piece, never overlapping another zone. Outlines follow real ZIP-code areas cut at county lines, smoothed; the line between two neighboring zones runs straight down the middle between their nearest ZIPs. City-owned (muni) utility areas are cut out. Energy communities Each zone card shows the share of its homes inside an IRA energy community (statistical-area counties per IRS Notice 2026-39; coal-closure tracts). It is shown for your planning; it does not move zone lines. Policy exclusions Excluded by GS policy even though the utility is eligible: Detroit, Highland Park and Hamtramck (their city limits) and Grosse Ile — credit fails. Neighbors like Grosse Pointe, Harper Woods, Ferndale, Hazel Park and Dearborn are IN. Excluded turf never enters a zone, a total, a dot or an export. Colors Every zone has its own vivid color; neighbors never share one. Amber counties are expansion candidates: at least the state’s zone minimum of dialable homes sits outside every zone there. Ranking (separate from the definition) My Recommendations orders zones by credit first (680 average required, median 700+ is a bonus; credit is metro-modeled), then a $75–125K Census median income sweet spot (≈ a $90–150K average), then pool size; preferred utilities rank first (Ohio: AEP Ohio and Ohio Edison).

Draw mode is ON — press and drag on the map to draw your zone in red. Release to close the shape and get its numbers. Export and Copy ZIP codes buttons then appear right below (same as a drivable zone). Tap the header to exit.

Add Dots to Zone◯▾

Step 1: tap Draw a loop, then press and drag on the map to circle the red dots you want. Every dot you circle goes to the zone you pick, even dots already in a zone.
