24. Public Involvement Steps with Lee County Obtain Park Usage Information Met with Park and County Officials Solicited Input on Color, Texture and Landscaping

25. Public Involvement Results The barrier was favored by Lee County The color selected was Dark Beige The texture selected was Ashlar Stone with smooth horizontal band and smooth posts Landscaping was encouraged, to include Creeping Fig

26. Barrier Aesthetics Selected

27. Conclusions A wide array of receiver points are required Single-use facilities rarely qualify for abatement Usage data can be difficult to obtain The methodology is relatively simple to apply

28. Any Questions? When’s the break? When’s lunch?? Are you done yet???
