6.0 CAPITAL IMPROVEMENT AND IMPLEMENTATION SCHEDULE

The recommended implementation schedule for each component of the Lake Tarpon Drainage Basin Management Plan is shown in Table 6-1. This table also lists the issues addressed and the responsible entities for each recommended component of the Plan.

Due to the documented concerns regarding the advancing trophic state of Lake Tarpon, it is recommended that most components of the Plan be initiated in some manner during 1999. For some Plan components, additional studies and monitoring are recommended prior to full implementation. These include: Structural Component 5 - Construct Pump Stations and Distribution Lines for the Storage and Beneficial Reuse of Lake Discharge Water, and Management Component 2 - Increase Lake Flushing and Dilution.

Due to their high capital costs, it is recommended that property acquisition and design activities for the major structural components of the Plan be intiated in 1999, but that construction be extended over a 10-year period. The major structural components of the Plan include: Structural Component 1 - Convert All On-site Wastewater Treatment Systems (Septic Tanks) in the Lake Tarpon Basin to Central Sewer Systems; and Structural Component 2 - Construct and Maintain Enhanced Stormwater Treatment Facilities in the Priority MHUs and Individual Sub-basins. For the latter management action, it is recommended that the land acquisition for all six facilities be completed by 2000, and that at least one facility be fully constructed and operational in 2002. Design and construction of the other five facilities should be staggered over a 10-year period based on available funding and trends in lake water quality. If warranted by continued poor water quality trends, it is recommended that the construction of all six facilities be completed by 2009.

7.0 FINANCING REQUIREMENTS AND OPTIONS

7.1 FUNDING REQUIREMENTS

An estimate of the total cost of financing the recommended Lake Tarpon Drainage Basin Management Plan is summarized in Table 7-1 below. The cost of implementing the Plan over a 10-year period has been estimated at $19,087,000. It should, however, be noted that design plans and specification have not been prepared for the major structural components of the Plan, and market-driven unit costs can vary significantly due to many factors. Nonetheless, the estimate of the total cost to implement the Plan was prepared with the best information available to date.

Table 7-1 Summary of costs for implementing the recommended Lake Tarpon Drainage Basin Management Plan.

Total Construction Cost

$12,887,000

Total Annual O&M Cost

Total Annual Administrative Cost

$292,000

Total Cost through Year 2008*

$19,087,000

* The total of construction costs plus five years of annual O&M and administrative costs.

In developing the cost estimates shown in Table 7-1, the total annual O&M and administrative costs represent estimates for annual recurring costs for these activities associated with the entire suite of projects and programs recommended in the Plan. Therefore, for the estimated total cost through year 2008, it was assumed that all recommended construction projects would be completed by the year end 2003, and that all facilities and recommended programs would be fully operational for a period of five years (from 2004 through 2008). It should, however, be noted that many matching fund grant programs, and other public funding sources, exist to defray the cost of Plan implementation. The various funding options for the Plan are briefly discussed below.

7.2 FUNDING OPTIONS

Based on the information obtained during this study, the following conclusions and recommendations can be made regarding funding options for the Plan.

Table 7-2 below provides a summary of the various components of the Plan and potential funding sources for each.
