The existing boat ramp and pier at Lake Forest is one of few public use facilities of its kind around the lake. Due to its design and location it provides safe and convenient access to thousands of users every year. The rehabilitation project included replacement and widening of the boat ramp in accordance with the California Department of Boating and Waterways’ design standards, and dredging of lake access to the previous dredged elevation of 6219’ to enable boat operation at lower lake levels. AEC was retained for civil design, permitting, construction support, as well as topographic and bathymetric surveys for design and planning purposes.
