Odio 1, �� Assistant City Manager �1 July 21, 1983 Dinner Key Marina Renovation and Expansion (City Commission meeting agenda item - July 28, 1.983) Four The Dinner Key Redevelopment Design Project (Phase I) is completed. The design contract with the firm of Greenleaf and Telesca requires a presentation of conceptual design to the City Commission for re- view and approval. The State of Florida D.E.R. and the U.S. Army Crops of Engineers have issued environmental permits for this project. The proposed Master Plan, as outlined in the attached Executive•Summary, has been endorsed by -the Waterfront Board, the Marina Users, Marina Industrial and Commercial Organizations, as well as environmental groups. The preliminary construction cost estimate of $6.2 million is responsive to budgetary goals and the design maintains all essential operational features and requirements. The design memoranda on Phase I, enclosed, consist of: Memo 1 - A structural analysis of existing pier 2 & 5, concluding that there is no alternative other than replacement. Memo 2 - Fleet Determination - Including a Dinner Key Marina user survey, future fleet projection, analysis of operational needs and recommended amenity package. Memo 3 - Conceptual Master Plan - Including preliminary cost estimate and a construction phasing schedule. Two drawings of the proposed Master Plan of the marina and landside perimeter development are included. It is anticipated that, upon authorization to proceed, the work required leading to final design and construction documents can be completed without interruption and that this project can be ready for the advertising of construction bids at the end of the year. It is recommended that this item be scheduled for a brief presentation at the July 28, 1983 City Commission meeting, so as to be able to proceed with the design. MOTION 83--'715i After Phase I is approved by the City Commission, two additional chases provide for the completion of the project, as follows: Phase II consists of: 1) Completion of the Marina design; 2) An economic feasibility and market study to be made by an independent contractor.
