Role of the Advisory Board

The advisory board of the BLMD determines which projects and programs consistent with the wording of the resolution will be most beneficial to the lake, based on current conditions and the overarching goals of the LMD. Once the work program is determined, the City of Sammamish, acting upon the advice of the LMD Board, contracts with public agencies or private contractors to complete the work. The city also manages the LMD budget.
