About TCA


Thornton Creek Alliance (TCA) is an all-volunteer grassroots, nonprofit organization dedicated to preserving and restoring an ecological balance throughout the Thornton Creek watershed. Our goal is to benefit the watershed by encouraging individuals, groups, schools, businesses, and government to work together in addressing the environmental restoration of the creek system including:  water quality, stabilization of water flow, flood prevention, and habitat improvement through education, collaboration, and community involvement.
