Biohazard Cleanup Near Whitley Place Prosper, TX

Prosper is an affluent suburban town in the Dallas–Fort Worth metroplex that straddles Collin and Denton counties, growing out of rich black-prairie farmland north of Dallas.

The first settlers arrived in the Prosper area in 1846 to farm cotton in the fertile black prairie soil.

Prosper grew out of two rival settlements — Rock Hill, two miles south, and Richland, one mile north — which merged when the St. Louis & San Francisco Railroad arrived in March 1902, making Prosper the central rail stop between Dallas and Sherman.

Prosper got its optimistic name by accident: when residents applied for a post office under the name 'Richland,' they were told it was already taken, and J.C. Slaughter suggested 'Prosper' because that year's crops had been very prosperous.

The Town of Prosper was incorporated in 1914 with a population of about 500, and its first mayor, U.N. Clary, went on to serve in the job for 49 years.

Prosper's population has exploded with suburban growth, rising from 9,423 in the 2010 census to 30,174 in the 2020 census, with the Census Bureau estimating about 45,605 residents by July 1, 2025.

The town covers about 22.8 square miles and was named the 5th Best Suburb in the Dallas metropolitan area on D Magazine's 2010 Best Suburbs list.

Prosper is served by the Prosper Independent School District, and its flagship Prosper High School cost $113.5 million to build — a 590,000-square-foot campus with a medical tech lab, a broadcast studio, a greenhouse, and an indoor football practice facility.

Prosper ISD has expanded to four high schools — Prosper, Richland, Rock Hill, and Walnut Grove, which opened in the fall of 2023 — to keep pace with the town's growth.

Prosper's Windsong Ranch community is built around a man-made crystalline lagoon, one of the signature amenities of the town's master-planned subdivisions.
