The Corps of Engineers studied shoreline erosion at Liza Jackson Park, a publically-owned park within the City of Fort Walton Beach. It was determined that the shoreline is receding at the long-term rate of about 1 foot per year. A plan was evolved which addresses the problems and met with the approval of the resource agencies and the public. The recommended plan provides for a beach about 450 feet long which, with periodic nourishment, would offset erosion and provide for water-oriented recreation benefits. Expansion of an existing salt marsh which presently occupies another 450 feet of shoreline would also control erosion while enhancing wildlife habitat. Erosion of the march would be prevented by a low rock stabilizing structure. Diversion and piping of an existing drainage ditch would help to nourish the marsh, to improve water quality, and to create safer, more esthetically pleasing, and more useful conditions in the park. The total first cost of the Selected Plan is estimated to be 236,000 and average annual equivalent benefits were estimeted to be 358,920 for a benefitcost ratio of 18 to 1.
