CATEGORY III – BRIDGE IMPROVEMENTS:
The development of the Bridge Improvement component of the Capital Improvement Program is based on the goals and objectives set forth in the Comprehensive Plan and the specific recommendations or action strategies set forth in the City’s Bridge Plan.
Comprehensive Plan Goal: “TO PROVIDE AND ENCOURAGE A MULTIMODAL TRANSPORTATION SYSTEM THAT MEETS THE CIRCULATION NEEDS OF MARCO ISLAND IN A SAFE AND EFFICIENT MANNER BUT DOES NOT ADVERSELY IMPACT THE QUALITY OF LIFE OF THE RESIDENTS.”
Comprehensive Plan Information – The City’s Comprehensive Plan is divided into two sections: Part 1 – Goals, Objectives and Policies; and Part 2 – Data and Analysis. Part 1 identifies the goal of the Transportation Element as listed above. The applicable Comprehensive Plan Objectives from Part 1 are:
· Incorporation of recommended improvements contained in the Bridge Plan that will enhance bridge safety and capacity into future capital improvement budgets
· The City will aggressively seek grants, and other funding sources to augment and expand the financial resources available for capital improvement projects.
Part 2 of the Comprehensive Plan discusses bridges as a component of the transportation network and references the Bridge Plan, from which the City will implement a capital improvement program to replace and/or renovate deficient bridges.
The State of Florida Department of Transportation (FDOT) is required by federal law to administer annual inspections of bridges statewide. Through contracted consulting services, FDOT conducts annual inspections of the City’s fourteen bridges for operational safety and structural integrity. One bridge (low vertical clearance) on Collier Boulevard at Amazon Court has not been inspected by FDOT. An evaluation rating system is employed consisting of four performance factors: (1) structural adequacy and safety; (2) serviceability and functional obsolescence; (3) essentiality for public use; and, (4) special features.
Right-of-Way Master Plan Recommendations: The Right-of-Way Master Plan (2000) discussed the need for special bridge design treatments, and included an overview of traffic concerns, pedestrian facilities, and aesthetic concerns. A total of ten bridges, including Smokehouse Bay Bridge, were identified in the Right-of-Way Master Plan as candidates for enhancements consistent with the design concepts advanced.
Consistency With Adopted Schedule of Capital Improvements: Based on the Adopted Schedule of Capital Improvements contained in the amended Comprehensive Plan, $6,800,000 as allocated to bridge improvement projects for the prior Five-Year CIP for FY06-FY10. Due to the costs associated with the reconstruction of North and South Collier Boulevard some capital expenditures, including bridge projects, have been deferred to future years or scaled back. Per the City’s adopted Comprehensive Plan, bridge improvements are not subject to Level of Service (LOS) standards. The Five-Year CIP for fiscal years 2007-2011 allocates $7,007,000 for bridge repairs.

Project #7: Smokehouse Bay Bridge Enhancements
Project Goal: “To perform aesthetic improvements and associated minor repairs to the Smokehouse Bay Bridge.”
Project Objectives:
1. To complete enhancement and associated minor repair work for the Smokehouse Bay Bridge in FY07 concurrently with or separate from the North Collier Boulevard improvement project.
Project’s Relationship to Comprehensive Plan:
· “Incorporation of recommended improvements contained in the bridge analysis study will enhance bridge safety and capacity into future capital improvement budgets.” (Section II, Objective 1.6)
· “The City will aggressively seek grants, and other funding sources to augment and expand the financial resources available for capital improvement projects.” (Section VIII, Objective 1.3)
Project’s Relationship to the Right-of-Way Master Plan:
· This bridge enhancement project is consistent with recommendations set forth in the Right-of-Way Master Plan, and is comprised of streetscape and sidewalk improvements that will result in substantial aesthetic improvements for this unique area of the City. Although the scope of work for this project does not explicitly include widening work or structural related repairs to the existing bridge, minor repairs and maintenance activities will be necessary and are considered to be inherent to accomplishing the beautification / enhancement work.
Success Measurement: Completion of design and construction stages in FY07 within the allocated budget.
Project Narrative: It is expected that initial planning efforts for this project will involve development of alternative aesthetic concepts to complement and maximize architectural benefits anticipated from the current Esplanade mixed use development project. In particular, the sidewalk component of the Smokehouse Bay Bridge enhancements will be designed to functionally and aesthetically integrate with waterfront pedestrian uses by the Esplanade developer. This FY08 project will be funded by previously awarded grants from FDOT. The total grant of $256,000 consists of a $100,000 appropriation for landscaping, and $156,000 for sidewalk construction. In FY09, it is anticipated that the southbound bridge will be redesigned. The new bridge profile will be increased to allow an
increase of three to four feet of additional waterway clearance as well as incorporating access under the bridge for pedestrians to allow for a boardwalk connection between the Esplanade and the Winn-Dixie property.
