TITLE:
Recommendation to approve presenting to the U.S. Congress for consideration in the 2008 Water
Resources Development Act (WRDA) two proposed Collier County water quality projects,
including Clam Bay Estuary improvements, and a Naples Bay conservation initiative entailing a
system of 10 Aquifer Storage and Recovery (ASR) wells along Golden Gate Canal, and a City of
Marco Island project request for Hideaway Beach erosion control and beach renourishment.

EXECUTIVE SUMMARY
Recommendation to approve presenting to the U.S. Congress for consideration in
the 2008 Water Resources Development Act (WRDA) two proposed Collier County
water quality projects, including Clam Bay Estuary improvements, and a Naples
Bay conservation initiative entailing a system of 10 Aquifer Storage and Recovery
(ASR) wells along Golden Gate Canal, and a City of Marco Island project request
for Hideaway Beach erosion control and beach renourishment.
OBJECTIVE: For the Board of County Commissioners (BCC) to review and approve
the three projects presented by county staff and the City of Marco Island for
consideration by the U.S. Congress in the 2008 Water Resources Development Act
(WRDA). The two projects proposed by county staff include Clam Bay Estuary
improvements, and a Naples Bay conservation initiative that entails construction of a
system of 10 Aquifer Storage and Recovery (ASR) wells along Golden Gate Canal. The
City of Marco Island project is for erosion control structures and beach renourishment on
Hideaway Beach, specifically located at Royal Marco Point.
Once officially approved by the BCC on April 22, 2008, Collier County's BCC-approved
2008 WRDA project proposals will be communicated to the county's elected
representatives in the U.S. House of Representatives in a transmittal letter to be signed by
the BCC Chairman on behalf of the Board. In that correspondence, Congressmen Connie
Mack and Mario Diaz-Balart will be asked to pursue funding for the projects along with
the county's other previously-approved WRDA authorizations.
CONSIDERATION: Collier County staff was notified by our lobbyist the week of
April 10-16 to propose additional potential projects for consideration by Congress in the
2008 WRDA legislation. In a needs assessment, county staff identified and recommended
the Clam Bay Estuary and Naples Bay/Golden Gate Canal ASR wells projects.
Clam Bay Estuary Water Quality Improvements (Map Attached)
The Clam Bay Estuary is a significant mangrove forest preserve located adjacent to the
Gulf of Mexico within Collier County that has experienced alarming increases in nutrient
loadings over the past several years. This project would consist of professional
engineering studies to determine the source and scope of these non-point source
pollutants and appropriate solutions to mitigate them. Studies anticipated are pollution
loadings models, hydraulic modeling, mixing studies, and stormwater runoff control
modeling. This project will fund engineering studics to determine what water quality
improvements are required for the Clam Bay Estuary and any resulting construction
required. Studies are expected to be completed within a year and estimated to cost
$250,000. (Map Attached)

Naples Bay/Golden Gate Canal ASR's
The project will include 10 surface water Aquifer Storage and Recovery (ASR) wells
placed adjacent to and along the Golden Gate Canal to divert fresh canal water before
discharging into Naples Bay, a Significantly Impacted Bay as defined by the State of
Florida. The diverted water will be utilized for irrigation during the dry (winter) season to
lessen the burden on the Florida aquifer system, which is significantly stressed
statewide. Excessive amounts of fresh water from the Golden Gate Canal introduce
dissolved oxygen (DO) into Naples Bay which kills off estuarine organisms and impacts
fish and wildlife. The project will extract canal water via ASR wells and pumps and
inject it into the aquifer below the ground surface for storage during the wet (summer)
season, a season of low or no irrigation demand. The stored water will be recovered via
the same ASR wells and pumps and utilized for irrigation purposes. This conservation
alternative will offset precious potable water supplies used for irrigation by
supplementing our reclaimed (treated wastewater) irrigation quality water supply.
The project will consist of professional engineering design, hydro-geologic, well and
appurtenances construction, and construction inspection services. The engineering
design and hydro-geologic services will be comprised of the following elements: a
public involvement program, data collection, and determination of feasibility
of 10 surface water ASR's, hydraulic and hydro-geologic analysis, and cost analysis.
These elements will be individually documented in a technical report form. Final
engineering design, including plans and specifications for bidding and construction will
be prepared.
The construction will include 10 ASR wells, well pumps, valves, site/civil, electrical,
instrumentation and controls, mechanical, piping, chemical treatment for disinfection,
fencing, and emergency generator(s).
Design will be completed one year from Notice to Proceed. Bidding and award will be
completed four months after bid opening. Construction will be completed three
years after the construction awardINotice to Proceed. Costs are estimated to be $6.26
million for permitting and engineering, $32.2 million for construction and $250,000 for
easement acquisition.
In addition, with passage of the WRDA legislation last year, Collier County received an
authorization of $5 million for Gordon River water infrastructure to improve water
quality, and $20 million jointly with Charlotte and Lee counties for water supply
interconnectivity infrastructure. Also, money was authorized for studies for Collier
County beaches and Vanderbilt Beach Lagoon. Subsequent to those WRDA
authorizations, when the Board approved on February 12, 2008 the Collier County Fiscal
Year 2009 Federal Legislative Agenda, among its nine (9) projects is funding for Water
Interconnects with Bonita Springs for tri-county connectivity as well as a Vanderbilt
Lagoon reconnaissance study. Given that Naples beaches were recently renourished, the
county will also seek that WRDA-authorized funding in future years.

Hideaway Beach Erosion Control and Beach Renourishment (Map Attached)
The City of Marco Island request is for funding the project entitled North Marco Island
Erosion Control and Beach Renourishment. The project description is to add six
additional erosion control structures, and inlet dredging in two borrow areas outside of
the Rookery Bay National Estuarine Research Reserve boundary. The location is Royal
Marco Point. The purpose is erosion control protection of a conservation area; flood
protection from the only access road to 312 residential units; and aid to restore navigable
pass to Big Marco Pass. The non-federal sponsor of the project is the Hideaway Beach
District Board.
Marco Island Interim City Manager Dana Souza said the City anticipates a 50 percent
match from ad valorem tax within the dependent tax district. He wrote that justification
of use of federal taxpayers' dollars for the project is the protection of the beach from
further erosion landward of the erosion control line and now threatening the adjacent
conservation area.
In Fiscal Year 2009, Commissioners, the Congressional Delegation, county staff, the
county's lobbyists and the community are continuing to work together to address the
needs of the citizens of Collier County.
In conclusion, the Board is being asked to review and approve Collier County's three
additional proposed 2008 WRDA projects to be considered by Congress that will be
communicated in a transmittal letter to our Congressmen, as requested, to be signed by
Board Chairman Tom Henning.
