This website has been developed through a Cooperative Assistance Agreement under the US EPA Office of Water 104b(3) Program in order to provide a web-based clearinghouse that allows researchers, practitioners, and program managers to collaborate and efficiently disseminate and share information with local governments, states, builders, developers, stakeholders, and environmental groups. The administrative and technical information available through this clearinghouse will be useful to permit writers, local government officials, watershed managers, and stakeholders.
