The report indicates that the location of the barrier "presents the only feasible option for adequately insuring protection" of the existing 170-acre development."
Alternative locations are mentioned in the staff report, but were dismissed for being too expensive or less feasible.
In its letter to the coastal commission, the land trust states that the barrier violates the local coastal program — the guidelines under which the coastal commission will consider the project.
The local coastal program prohibits the building of protective devices as part of new developments.
But the local coastal program also states in another passage that, "Drainage systems and other such facilities necessary to ensure public health or safety may be allowed provided that bluff alteration is restricted to the minimum necessary and is done in the least environmentally damaging feasible manner."
