• Obtain a master use permit for any use or change of use in the Shoreline District
• Use best management practices in the shoreline to minimize and mitigate impacts on the aquatic environment
• Obtain and display a City-issued identification number for a floating residence (learn about the Floating Residence verification and registration process)
