Signal Creek

Thornton's second master-planned community and one of its first upscale neighborhoods, modern Traditional, Craftsman, Colonial, and Tudor-revival homes built throughout the 1990s with walkable, tree-lined streets and well-maintained green spaces. The Olympic-size pool and low $42/month HOA dues make it an enduring favorite. Homes don't stay on market long.
