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.
* 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.
Funding
available from the EPA Clean Lakes Program has been underutilized in Florida in past
years, and current funding cuts now threaten the viability of the entire program.
Political support of the Clean Lakes Program by Pinellas County is recommended.
Federal grants
under the EPA 319 program could be used to fund the proposed stormwater rehabilitation
projects. In addition, funds made available under Section 319(C) of the program could also
potentially be used to connect those residences currently using OWTS to a central sewage
collection and treatment system. Pinellas County and the City of Tarpon Springs should
further pursue this grant program.
Cooperative
funding from the Pinellas-Anclote River Basin Board should continue to be sought to the
greatest extent feasible. This funding source, being generated by ad valorem taxes,
represents perhaps the single most stable and predictable funding source for water
resource and lake management initiatives in Pinellas County.
Currently, the
funding of District SWIM programs is dependent upon a yearly appropriation from the
Florida Legislature. Funds generated by FDOT contributions to the Ecosystem Management
Trust Fund for mitigation purposes are being evaluated as a potential long-term funding
source for the District SWIM programs. Such funds are to be used for aquatic weed control
programs, habitat restoration planting programs, and other remediative programs associated
with eutrophication. Pinellas County should continue to closely track the rulemaking for
this legislation to determine if such funds will be available through District cooperative
funding programs in the future.
Pinellas County
should consider the creation of a stormwater utility to provide a long-term, stable
funding source for drainage and water quality improvement projects. In addition to the
"Penny for Pinellas" sales tax, a stormwater utility could provide the County
with a long-term and stable source of needed funding for continuing the watershed
management initiatives already underway.
Pinellas County
should undertake a survey of lakefront and watershed property owners to determine if a
Municipal Service Taxing Unit (MSTU) would be supported. If initial support is indicated,
Pinellas County should give strong consideration to this management option in lieu of
general revenues or a stormwater utility.
A local boat
registration fee is considered to be the most cost-effective and equitable approach to
collecting user fees; however additional manpower will be needed to administer and enforce
such a program.
Table 7-2 below
provides a summary of the various components of the Plan and potential funding sources for
each.
