Why
Timeline of Events
2005:
• Florida Legislature Revised Ch. 373 F.S.; required
Regional Water Supply Plans
LAW / CODE
Section 373.0361(1), Florida Statutes (F.S.) provides:
The governing board of each water management district
shall conduct water supply planning for any water supply
planning region within the district identified in the appropriate
district water supply plan under Section 373.036, where it
determines that existing sources of water are not adequate to
supply water for all existing and future reasonable-beneficial
uses and to sustain the water resources and related natural
systems for the planning period.
2007:
• SFWMD Adopted Lower East Coast (LEC) Water
Supply Plan Update and the Water Availability
Rule
– Allocation limited to 2006 usage (8.53 MGD) - base
allocation
– Shortfall of 1.87 MGD within the planning period
(Year 2025)
– Implement LEC Water Supply Project (RO System @
$17M)
2007 Continued:
– Confirm within one year other Alternative
Water Supply (AWS) projects as substitute
for RO
– Annual Progress Reports
– 10-year Water Supply Facilities Work Plan
with the AWS Project
– Update City’s Comprehensive Plan
3. Your water supply entity must notify the District if it proposes to develop
other water supply development projects {Subsection 373.0361(7)(b), Florida
Statutes).
If your water supply entity does not intend to develop one or more of
the water supply development projects identified in Appendix A for your
water supply entity, it must:
• Propose to the District, within one year after receiving this notification,
other alternative water supply development projects sufficient to
address the projected water supply needs for your water supply
entity, as presented in the 2005-2006 Lower East Coast Water Supply
Plan Update.
• Provide an estimate of the quantity of water to be produced by the
project and the project's expected start and completion dates.
• Describe the status of the project's implementation, including:
o Financial planning.
o Facilities master planning.
o Permitting.
o Activities/efforts in coordinating or participating in
multijurisdictional projects, if applicable.
2007 - 2008:
• Completed AWS Alternatives Evaluation;
alternatives considered:
AWS Alternatives
Floridan RO
Recharge Via Canal Discharge
Recharge Via GW Injection
Reuse Plant @ WWTP/Irrigation
Reuse Plant @ Remote
Location/Irrigation
Cost
$19.0 million
$16.5 million
$17.5 million
$9.3 million
$14.3 million
2007 – 2008 Continued:
• Completed 10-Yr Water Supply Facilities Work
Plan
• Completed Rate Study with 10-Yr Financial
Forecast, as required, and incorporated into the
10-Yr Work Plan
• Adopted and implemented rate increase
(FY 2009-2012)
2007 – 2008 Continued:
• Amended the Comprehensive Plan to
incorporate the Work Plan
• Notified SFWMD of the City’s intent to develop
Reuse Plant
2009 - 2010:
• Project planning/design/negotiations with large
users (golf courses)
Project Status
Design complete for the Reuse Plant
• Received approvals from permitting agencies
• Confirmed (by e-mail) credit towards allocation
from SFWMD….awaiting written confirmation
• Bidding and construction permits….pending
60% Design complete for the piping to golf
courses
Agreements with three (3) golf courses in place
Project funding….budgeted in FY 13 (Source:

Staff Recommendations
• Reuse Project – Put on hold
• Prioritize Option 2 and 3
– Complete WWTP piping modifications +
aggressively implement Conservation Program
• Monitor Population Projections Closely
– Update and implement Reuse Project, if/when
needed
City Commission
• Consensus vote on staff recommendations
