The purpose of this study is to identify the problem in Bolinas Lagoon, identify the opportunities for restoration and constraints to project development, develop planning objectives for the study, and develop a solution that addresses those planning objectives. The overall goal of the project is to find viable alternatives that provide long term benefits to the lagoon ecosystem while minimizing adverse, short term impacts. 2.0 Measures and Alternatives Considered Restoration measures considered in this study include wet sediment dredging and dry sediment excavation activities in the North Basin, Main Channel, Pine Gulch Creek Delta, Kent Island, Bolinas Channel, Highway One Fill Areas, South Lagoon Channel, Dipsea Road and Seadrift Lagoon.
