Sacramento sits only 26 feet above sea level on flat river land, with about 76 days a year at 90 degrees or hotter. Summer heat, irrigated yards and the rivers' moisture suit termites, mosquitoes and roaches.
As California's capital and the seat of Sacramento County, Sacramento had 524,943 residents in the 2020 census. Roughly 100 square miles of flat land stretch across the confluence of the Sacramento and American Rivers, and Mayor Hardin Bigelow oversaw its first levee after a flood in January 1850. Land to the west is reserved as the Yolo Bypass flood basin.
Known as the City of Trees, Sacramento has a dense canopy over many streets in Land Park, East Sacramento and Curtis Park. Summer afternoons are hot, but the delta breeze from San Francisco Bay cools nights, and about 18 inches of rain falls from November to April. Old trees, irrigated lawns and river water give pests a dependable supply of shelter and moisture through the dry months.
