WSDOT needs permits to work in or over the water. The Department of Ecology and the Washington Department of Fish and Wildlife issue general permits for specific routine maintenance and preservation activities that have a low risk of impacting sensitive resources. A general permit covers the same type of work across the state and is good for five years. It streamlines the process and saves time and money by eliminating the need to apply for a new permit each time the work is performed.
