Collier County, Florida
Collier County is Florida's second-largest county by land area and one of its wealthiest, running from the luxury coastal market of Naples and Marco Island east across Golden Gate Estates to the agricultural community of Immokalee and the Everglades. Most of the county is conservation or rural land, so growth concentrates in a narrow coastal band and the eastern rural-lands villages — making boundary and land-use context essential.
