Plano covers about 72 square miles of Collin County, and its parks and preserves, including 800-acre Oak Point and 200-acre Arbor Hills, run beside dense housing and office parks. Green corridors and warm summers give pests food, water and shelter close to doors.
Plano is the largest city in Collin County, with 285,494 residents at the 2020 census, and a small piece of it reaches into Denton County. It sits about 715 feet above sea level on roughly 72 square miles. The city draws its water from Lake Lavon through the North Texas Municipal Water District, and Rowlett Creek flows near Bob Woodruff Park on the east side.
Parks tie much of the city together: Bob Woodruff Park and Oak Point Park are linked by trails, and a tree in Bob Woodruff Park is estimated to be over 200 years old. Climate is humid subtropical, and May is the wettest month on average. Wet springs, parkland and 107,320 households give termites, roaches, wasps and mosquitoes a lot to work with.
