The petition for review contests the City of Bainbridge Island's new Shoreline Master Program (SMP), asserting it violates Washington state law and the Shoreline Management Act (SMA) by improperly managing single-family residential use and lacking compliance with public participation requirements. The petitioners argue that the SMP's implementation process was flawed, leading to regulatory inconsistencies and infringements on property rights. Additionally, they raise concerns about the city's failure to adequately use scientific data in the development of the SMP, which they claim disproportionately impacts residential properties.
