Irvine Company proposes to remove on slip finger and two piles from Bayside Marina where the dock layout bends with the bulkhead. The slip finger limits the effective, economic use of the water surface which can only accommodate dingy size boats at this location. Removal of the slip finger will allow use by larger boats and therefore enable a more cost effective use of the water space.
Removal of the slip finger will create 212 sq. ft. of open water and increase soft bottom area by 1.57 sq. ft. with removal of the two support piles. Bottom sediment surrounding the base of the support piles will be excavated below the mudline and stockpiled temporarily while the piles are cut two feet below the mudline and then returned and the space refilled on the pile cutoff is complete. Best management practices will be employed to ensure construction debris or other contaminants will not enter the bay waters. Any debris entering the bay will be retrieved and disposed of within 72 hours of occurrence. No access to the marina will be impeded by this project.
Categorical Exemption Class 1, Existing Facilities, consists of the operation, repair, maintenance, permitting, leasing, licensing or minor alteration of existing public or private structures, facilities, mechanical equipment or topographical features involving negligible or no expansion of use beyond that existing at the time of the lead agency's determination. Section (l)4() allows the demolition and removal of accessory (appurtenant) structures including garages, carports, patios, swimming pools and fences. The types of facilities listed are not intended to be all-inclusive of the type of project which might fall within Class 1. The removal of one slip finger and two supporting piles will not involve expansion of an existing use and, therefore, will not result in environmental impacts. Rather, the Project will create an opportunity for useable water space to accommodate larger boat sizes than is currently possible due to the existing slip finger configuration. City standard conditions of approval and the provision of best management practices during project demolition will further ensure that the project does not impact the environment.
