Peoria is an Illinois River city with a manufacturing heritage centred on Caterpillar, which maintains its world headquarters nearby. The city's bluffside topography along the Illinois River means that many Peoria residential properties are on hillsides — a characteristic shared with Charleston WV and giving some Peoria homes walk-out basement access that flat-terrain cities don't have. Ameren Illinois serves electricity; Nicor Gas serves natural gas independently. Illinois contractor licensing applies. The -4°F design temperature and 36-inch frost depth put Peoria solidly in cold-climate heat pump territory.
