Agenda 02/26/2013 Item #16F52/26/2013 16.F.5.
EXECUTIVE SUMMARY
Recommendation to approve Collier County Guiding Principles that apply to RESTORE
Act funding and direct staff to coordinate a Selection Committee to review proposed
projects.
OBJECTIVE: Collier County has been identified as one of 23 Gulf coastal counties to be
impacted by the Deepwater Horizon oil spill of April 2010 and eligible for funding through the
RESTORE Act, federal legislation passed last summer mandating states and counties be
compensated for resulting damages. The amount of funding will be based upon criteria
established in the Clean Water Act and depends on civil penalties yet to be settled with parties
determined responsible for the accident. Counties are preparing project lists in advance of receipt
of funds. Because Collier is one of the impacted Gulf coastal counties, the Board of County
Commissioners (BCC) and the County Manager's Agency staff have been monitoring the
RESTORE Act process since August 2012.
In pursuing RESTORE Act funds, the Board of County Commissioners (BCC) is being asked
today to adopt the Collier County - specific Guiding Principles below. These local Guiding
Principles will need to be applied to project proposals, along with Allowable Uses developed in
the bill. The BCC is being asked also to direct staff to coordinate a Selection Committee
comprised of external stakeholders and county staff which will review projects and present to the
BCC a vetted list of final candidates in June 2013.
CONSIDERATION:
County Commissioners and staff from Monroe to Escambia counties began attending monthly
meetings held to address the RESTORE Act, which was co- sponsored by Senators Bill Nelson
and Marco Rubio, and passed as an amendment in the federal Transportation Bill that was
approved by the U.S. Congress in June and signed by President Barack Obama in July 2012.
Passage of the RESTORE Act — which means Resources and Ecosystems Sustainability, Tourist
Opportunities, and Revived Economies of the Gulf Coast States Act of 2012 — may translate into
millions of dollars for Gulf counties impacted by the oil spill tragedy and its repercussions.
The legislation holds the parties responsible for the Gulf oil disaster accountable for restoring the
Gulf. By investing fines owed by British Petroleum (BP) and the other parties responsible for the
Gulf oil spill into the Gulf region, the RESTORE Act will provide significant resources to
Collier County.
In January the BCC approved Collier County joining the Consortium which is administering one
of three funding opportunity "pots" containing dollars from civil penalty settlements according to
the Clean Water Act. (See Ocean Conservancy diagram attached.)
Staff requests the BCC adopt the following GuidinLy Principles relating to project proposals:
Packet Page -2059-
2/26/2013 16. F.5.
1. Projects provide positive environmental and economic benefits, including job creation.
2. Projects are consistent with local government comprehensive plans and community priorities.
3. Projects incorporate other funding partners to fully leverage grant resources.
4. Projects meet the funding criteria set forth in the RESTORE Act.
5. Projects selected will be diverse and address all our community's eligible needs, including
coastal and ecosystem restoration and development, flood protection, and tourism promotion.
The recommendation is also that the BCC direct county staff to communicate and coordinate a
Selection Committee which will include the following stakeholder representatives: City of
Naples, City of Marco Island and Everglades City; Conservancy of Southwest Florida, Rookery
Bay National Estuarine Research Reserve, Big Cypress Basin, Tourism Development Council
and Collier County Marine Industries Association.
The eight (8) external committee members will join the following (internal) county staff:
William Lorenz, Natural Resources Director; Gary McAlpin, Coastal Zone Programs Manager;
Jerry Kurtz, Surface Water and Environmental Planning Manager; Jack Wert, Tourism Director;
and Debbie Wight, Legislative Affairs Coordinator.
The 13- member Selection Committee will receive proposed projects from all interested parties,
review and evaluate, and present to the BCC a prioritized list of projects to evaluate and consider
for funding. Process updates will be posted on the county's RESTORE Act website:
http://www.colliergov.net/index.aspx?pave=7066
The Guiding Principles are intended to localize the criteria as well as supplement the following
Allowable Uses that are required for RESTORE Act funding:
• Restoration and protection of the natural resources, ecosystems, fisheries, marine and
wildlife
habitats, beaches, and coastal wetlands of the Gulf Coast region
• Mitigation of damage to fish, wildlife, and natural resources
• Implementation of a federally approved marine, coastal, or comprehensive conservation
management plan, including fisheries monitoring
• Workforce development and job creation
• Improvements to or on State parks located in coastal areas affected by the Deepwater
Horizon oil spill
• Infrastructure projects benefitting the economy or ecological resources, including port
infrastructure
• Coastal flood protection and related infrastructure
• Activities to promote tourism and seafood in the Gulf coast region
The three (3) available funding pots, from left to right on the attached diagram, are defined
below:
2
Packet Page -2060-
2/26/2013 16.F.5.
Opportunity "pot" 1 — Thirty-five (35) percent to be divided equally among the five Gulf of
Mexico states, or up to nearly $1.5 billion for each state. A 2011 Florida law says 75 percent of
the state's share of this pot, up to $1.1 billion, must go to the eight hardest hit Gulf counties in
Northwest Florida, and 25 percent, which could amount to $367 million, will be divided among
the 15 non - disproportionately impacted counties, including Collier County. The 15 non-
disproportionately impacted counties will receive funding based on a formula that considers the
weighted average of the population of the county, the weighted average of the county per capita
sales tax collections estimated for fiscal year 2012, and the weighted average distance from the
Deepwater Horizon oil rig to each of the nearest and farthest points of the shoreline. Assuming
that Collier County is average in its qualification based on the formula, Collier County could
receive between $6 and $24 million. The County Commission will have responsibility for
approving Collier's spending plan for this pot.
The Secretary of the Treasury is collecting data and establishing the formula distribution of the
funds, which will occur at any time. The County Commission is responsible for approving
Collier's final local projects and spending plan. These formula funds are definite. There is no
immediate deadline for these projects. The recommendation is to have a project list prepared
when Clean Water Act civil penalties are settled.
At today's Feb. 26 meeting, the BCC and county staff invite public agencies, external
organizations and private individuals as well as any other interested stakeholders to submit
their project proposals for consideration. Attached are a RESTORE Act info sheet and a
RESTORE Act interest form which will assist you in submitting projects based on the Guiding
Principles and Allowable Uses. The deadline for submissions is April 9.
Opportunity "pot" 2 — Thirty (30) percent, up to $6.3 billion, to be distributed by a federal -state
Gulf Coast Ecosystem Restoration Council to carry out the comprehensive restoration plan.
Collier County staff completed project proposal forms, one for each of the top four ranked
structural initiatives from the BCC - approved Watershed Management Plan.
The project proposal was created by the three Southwest Florida National Estuary Programs
(NEP's). The Charlotte Harbor, Sarasota Bay, and Tampa Bay National Estuary Programs are
assisting with coordination of a Southwest Florida Regional Ecosystem Restoration Plan.
The Regional Estuary Plan will develop a prioritized list of environmental projects that would
restore and protect the natural resources, ecosystems, water quality and coastal wetlands of
Southwest Florida, consistent with the federally- approved actions in the NEP's Comprehensive
Conservation and Management Plans (CCMP's). These four proposed Collier County projects
are consistent with the goals of the NEP CCMP's.
Staff forwarded this information on to the NEP's on Nov. 5, 2012. The four (4) Collier County
initiatives have been included in a list of projects based on the NEP's regional approach planned
for seeking RESTORE Act funds. The federal Council will be determining which projects will
receive funding by July 2013.
Packet Page -2061-
2/26/2013 16. F. 5.
Florida's Governor's office will be leading the development of proposals for funding that will be
transmitted to the Gulf Coast Ecosystem Restoration Council for review and approval. This is
the only opportunity that includes time constraints. The federal Council has 180 days — by
July 2013 — to decide on a project list. As of last month, 250 projects had been submitted.
Opportunity "pot" 3 — Thirty (30) percent, up to $6.3 billion, to pay for state proposals for
environmental restoration and economic recovery work. These plans must be approved by the
federal Council and will allow states to undertake projects and programs to restore /protect
natural resources, ecosystems, fisheries, marine and wildlife habitats, beaches, coastal wetlands,
and the economy of the Gulf Coast. Coordinated by FAC, creation of the Consortium
representing 23 affected Gulf coastal counties, was included in the RESTORE Act legislation for
the State of Florida, an action that protects home rule authority of local governments rather than
turning all funds over to state government for disbursement.
The Governor's office is partnering with the Consortium to determine the process for inclusion
of projects in these state proposals for environmental restoration and economic recovery work.
Everglades infrastructure may be a focus of proposals that will be advanced by the State, as
using oil spill money in the western Everglades might allow more federal and state restoration
funding to be devoted to the central and eastern Everglades. Governor Scott has included $60
million for Everglades restoration programs in his State Fiscal Year 2014 budget.
This funding will be allocated to the five (5) Gulf states based on an allocation formula that
includes number of miles of oiled shoreline per state compared to total miles of oiled shoreline;
average distance of oiled shoreline to BP Deepwater Horizon oil rig of each state; and the
average population of coastal counties based on 2010 Census. There is no deadline for these
projects at this point. Staff and other parties continue to develop this list internally.
The link below provided by the Florida Department of Environmental Protection (FDEP) shows
the beginning of the partnership with Governor Scott and his State agencies. Consortium
leadership believes this vehicle for submitting projects is the best opportunity for Florida to
maximize resources for restoration:
hM: / /www dep state fl us /deepwaterhorizon /,projects restore act htm
The FDEP site reads:
In order to provide an opportunity for the public to suggest potential projects for the Council
Comprehensive Plan, the DEP has created an online project submittal form. Project submittals
will be evaluated carefully by DEP in consultation with the Florida Fish and Wildlife
Conservation Commission, and selected projects will ultimately be submitted to the Council by
the Governor for consideration for inclusion in the Comprehensive Plan.
The Selection Committee invite letters to external stakeholders will be sent, along with Info Page
and Interest Form, immediately following the Feb. 26 BCC meeting. Natural Resources will
receive proposed projects from internal and external parties Feb. 26 through April 9. The
Selection Committee will hold review meetings April 10 through May 21 to evaluate,

categorize and prioritize projects. The Selection Committee will determine the optimum funding
pot for each proposed project. The County Manager will review the final list from May 22
through June 11. The BCC will be presented with a final prioritized list of projects by the
Selection Committee /CM on June 25, 2013.
FISCAL IMPACT: There is no fiscal impact associated with this executive summary.
GROWTH MANAGEMENT IMPACT: There is no growth management impact associated
with this executive summary.
LEGAL CONSIDERATIONS: There are no legal considerations associated with this

RESTORE ACI
Following the Deepwater Horizon Oil Spill of April 2010 in which 11 workers lost their lives in
the explosion and 200 million gallons of oil gushed unabated into the Gulf of Mexico for three
months, the Florida Association of Counties (FAC) and a group of lobbyists advocated at the
onset to assist the eight (8) most impacted "disproportionate" counties. As lobbying efforts in
Washington, D.C. increased, FAC had included 15 "non- disproportionately," or less affected,
Gulf counties. Collier County is one of those 15.
Since July 2012, County Commissioners and staff of Gulf coastal counties from Monroe to
Escambia have been meeting monthly to address the RESTORE Act, which was sponsored by
Senators Bill Nelson and Marco Rubio, and passed as an amendment in the federal
Transportation Bill that was approved by the U.S. Congress, then signed by President Barack
Obama in July 2012.
Passage of the RESTORE Act - which means Resources and Ecosystems Sustainability, Tourist
Opportunities, and Revived Economies of the Gulf Coast States Act of 2012 - may translate
into millions of dollars for Gulf counties impacted by the oil tragedy and its repercussions.
FAC officials have no expectations when the proceeds from the Clean Water Act penalties will
benefit the Gulf Coast Restoration Trust Fund which then will be allocated to the following:
• From the 3 5 percent "county" pot, funds will be split equally among Alabama, Florida,
Louisiana, Mississippi and Texas. The funding could be anywhere from about $5
million to more than $20 million for Collier County. Local projects will be submitted
and the County Commission will approve projects for allocations.
• Re the 30 percent pot of money, the "federal" allocation, the Gulf Coast Ecosystem
Restoration Council will implement a recovery plan.
• The Consortium comprised of Commissioners directs the "state" pot of funding which
is also 30 percent distribution. These funds are competitive and go to each of the 23
Gulf Coast counties based on projects reviewed by federal -state Council.
Collier County joined the Consortium when it approved the Interlocal Agreement at the Jan. 8
Board of County Commissioners (BCC) meeting. Commission Vice Chair Tom Henning is BCC
Consortium Representative and Commissioner Donna Fiala is the Alternate.

RESTORE Act Ecosystem Restoration Project Proposals
for consideration in the Gulf Coast Ecosystem Restoration Council's Comprehensive Plan
2012
Contact Information: Jerry Kurtz, P.E., Principal Project Manager
Date of Submittal:
November 5, 2012
Name of Project: North Golden Gate Estates (NGGE) Flowway
Org and Rank: Collier
Restoration Project
County, Florida
Project Description:
The NGGE Flowway Restoration Project will address long- standing water resource issues that
affect not only the human populations and natural areas of NGGE (approximately 34 square
miles), but also those of downstream systems and communities. The project proposes to install
ditch blocks and equalizing culverts (Attachment 1) in order to reconnect historic flowways in the
project area (Attachment 2). A hydrologic model of the study area has been created to determine
the appropriate location of ditch blocks and culverts. The project may include the purchase of
residential lots for additional water storage and treatment and will allow for improved timing of
freshwater discharges into the Golden Gate Main Canal and therefore Naples Bay.
This project will be designed to maximize benefits to natural systems, including hydrologic and
habitat enhancement and connectivity within NGGE, hydrologic benefits to downstream natural
systems and waterbodies, and provide increased flood protection for residents.
Project Location: Collier County
An area in North Golden Gate Estates, covering approximately 34 square miles, encompassing all

Quantify Environmental Results and How to Measure Them:
Results will be measured in improved hydrology to wetlands in the NGGE Flowway and
increased Flood lain Levels of Services.
Packet Page -2068-
2/26/2013 16. F.5.
Economic Benefits (including ecosystem services): This project will result in improvements to
the hydrology of wetland areas and to the timing of freshwater discharges in the Golden Gate
Main Canal. Based on the ecosystem service values derived in Costanza et. Al. (1996), this
project will benefit areas with combined ecosystem services values currently over $81,000,000
per year. The installation of ditch blocks and culverts throughout the project area will produce
area hydrology and groundwater recharge rates more similar to pre- development conditions and
therefore increase the ecosystem services values within the project area.
Estimated number of Jobs Created or Preserved: 52 (Estimate based on 1 job per $100,000)
How much Habitat will be restored and conserved ?:
The entire project area will experience restored wetland hydrology and improved aquifer
recharge. Final design may require the purchase of some residential parcels for additional water
storage. The project area is approximately 34 square miles.
Quantify pollutant reductions:
A preliminary estimate of pollutant reduction was done by WBID for the NGGE flowway project
as part of the Collier Watershed Assessment. The calculations assume that 1 inch of runoff is
treated from WIBID 32785 — North Golden Gate and WBID 3278H — Faka Union North
Segment, approximately 20 square miles the total area. It also assumes that much of the pollutant
loading is from Low Density Urban land uses. The calculations are:

What living coastal /marine resources will be improved and by how much ?:
The project will result in water quality treatment and improvements throughout the watershed and
freshwater discharges to Naples Bay will be restored to a more natural timing. Aquifer recharge
will be improved through increased water storage in the project area.
How will community resilience be enhanced?
The NGGE Flowway Restoration Project will improve flood protection to residents within the
project area. Use of low lying areas to attenuate peak runoff flow currently directed to the canal
system could result in a reduction in frequency of which canal capacity limits are exceeded.
Naples Bay will experience reduced input frequency of excess total volume of surface water flow
with improvement in the timing of freshwater inputs /discharges.
The project area also contains two important public water supply wellfields (Collier County
Utilities and City of Naples Water Utility) which are recharged by surface water. Proper
management of surface water is critical in sustaining the long -term drinking water yield from
these two wellfields.
Additional Justification:
Historically, the area that is now North Golden Gate Estates (NGGE) consisted of a mosaic of
wetland and upland habitats, including upland pine and hammock communities interspersed with
cypress and hardwood forests and herbaceous marshes and wet prairies. During the wet season,
Packet Page -2069-
2/26/2013 16. F.5.
water flowed across the landscape in a generally south - southwesterly direction, eventually making
its way into areas of Picayune Strand, Belle Meade, and Henderson Creek. The development of
NGGE was completed in the late 1960's as part of what was to be the largest subdivision in the
world. Large drainage canals were constructed and a network of roads was built. The canals
successfully drained much of the surface water and shallow groundwater in the area, making the
land available for human settlement. Many of the wetlands near the canals have transitioned to
disturbed upland communities, and the hydroperiods of remaining wetlands have been severely
altered by the drainage from the canals as well as roads that have created impediments to
sheetflow.
The project area includes land that currently drains into the Golden Gate Canal which flows to the
west and eventually into Naples Bay; and the Miller and Faka Union canals which flow south to
the Ten Thousand Islands estuary through the Picayune Strand State Forest. The flow from the
Golden Gate Canal into the Naples Bay through the Gordon River causes rapid and severe
fluctuations in salinity, which continues to cause significant harm to the Bay. The Miller and
Faka Union canals extend into the Picayune Strand Restoration Project, which will be plugging
these canals south of NGGE to restore overland sheetflow and wetland habitat. Presently there is
a very limited effective stormwater management/treatment system within NGGE. Stormwater
runoff is conveyed by inconsistent roadside swales and driveway culverts to the three primary
canals. The conveyance capacity of the Miller, Faka Union and Golden Gate canals are limited to
less than 10 -year peak flow rates. Localized flooding occurs in many areas as a result of high
rainfall events. Some of the deepest wetlands within NGGE have remained undeveloped, namely
Winchester Head and Horsepen Strand, although their hydrologic functions have been altered.
Current NGGE Flowway Restoration efforts include the January 2013 scheduled completion of
phase 2 of the study which began in 2006 as part of the Horsepen Strand Conservation Area
(HSCA) Feasibility Study. Work includes refinement of the original database and hydrologic -
hydraulic analyses of the NGGE watershed and canal system originally created by the SFWMD
Big Cypress Basin, subsequently refined and updated by the recently completed Collier County
Watershed Management Plan. Phase 2 study deliverables include preliminary engineering
alternatives for use in a stakeholder input and consideration processer with subsequent selection
of the most appropriate project. This will be followed by commencement of design, permitting,
approval, land acquisition and construction.
Though Collier County is outside the study area of the CHNEP CCMP, this project would support
several of the quantifiable objectives and priority actions identified in the plan (pg 86), including:
• HA -2... [to] restore, enhance and improve where practical historic watershed boundaries
and natural hydrologies...
• HA -G: Reestablish hydrologic watersheds to contribute flows to their historic receiving
water bodies.
• HA -J: Build and restore water conveyances to have shallow, broad, vegetated and
serpentine components that also restore floodplains.

Contact Information: Jerry Kurtz, P.E., Principal Project
Date of Submittal:
Manager
November 5, 2012
Name of Project: North Belle Meade Spreader Swale
Org and Rank: Collier
County, Florida
Project Description:
This project includes planning, design and construction of appropriate infrastructure to divert up
to 1,000 cubic feet per second (cfs) of surface water flow from the Golden Gate Main canal south
into the Northern Belle Meade area. (Attachment 1 - project graphic incorrectly indicates a
100 cfs diversion.) Different flow diversion amounts will be considered and could be phased in
over time. This facility would be used primarily during the rainy season to reduce flow in the
Golden Gate Main Canal currently going west to the Gordon River and Naples Bay. Diverted
surface water would flow south through the Northern Belle Meade area toward South Belle
Meade and Rookery Bay. Project considerations are still being conceptually evaluated. Possible
scenarios to be considered include a pump station to assist the diversion, a spreader swale, an
overland flowway, and conveyance through existing and future quarry mining lakes.
The project is predicted to reduce the volume of discharge to Naples Bay by 10 percent and will
provide treatment of the diverted water in the wetland systems. The project is also predicted to
increase freshwater discharge to Rookery Bay by 19 percent. Full design would need to consider
the conveyance capability of the culverts under I -75 and the affect of the existing borrow
excavation areas on the north and south side of I -75.

Quantify Environmental Results and How to Measure Them: Environmental benefits will be
measured in freshwater discharge reduction to Naples Bay and improvements to the
h dro eriods of wetlands in North and South Belle Meade.
Economic Benefits (including ecosystem services):
The project will improve water quantity conditions to both the Naples Bay and Rookery Bay.
While the value of the seasonal changes in discharge rates is difficult to quantify, the ecosystem
service value can be estimated of the areas to experience improvements. Based on the ecosystem
Packet Page -2076-
2/26/2013 16. F.5.
service values derived in Costanza et. Al. (1996), this project will benefit areas with combined
ecosystem services values of approximately $19,000,000 per year (Attachment 3). This figure
represents the value of services provided according to the surface area of the estuaries which will
receive a benefit as a result of the diversion. Additional economic benefits will be realized as a
result of the future seagrass restoration projects which will only be possible once freshwater
discharge imbalances have been improved.
Estimated number of Jobs Created or Preserved: 70 (estimate based on 1 job per $100,000)
How much Habitat will be restored and conserved ?:
Flowway easements for the discharge area may be preserved, but the exact size and location is
subject to final design considerations. Both Naples Bay (1066 surface acres) and Rookery Bay
(1034 surface acres) will experience hydrologic restoration in the form of freshwater discharges.
Wildlife habitat will be improved as the North and South Belle Meade Areas include wildlife
habitat for animals like the Florida black bear and the Florida panther. Acreage of wildlife
habitat to be preserved will depend on the land acquisition scenario utilized to create the
discharge flowwa .
Quantify pollutant reductions:
Preliminary calculations have been completed based on two different scenarios show below. The
first (Water Quality Losses Portion) assumes diversion directly into a spreader swale system,
based on a 200 cfs diversion. This indicates a large reduction to Naples Bay pollutant loading.
The second (Water Quality Wetland Treatment Portion) estimates the load removed by the flow
through the North Belle Meade Area.

What living coastal /marine resources will be improved and by how much ?:
In Naples Bay, the reduction in freshwater flow will improve habitat for seagrasses, improve
salinity and reduce nutrient levels in the freshwater flowing from the Golden Gate Canal. These
improvements will be enhanced in proportion to the freshwater flow reduction of 10 percent.
Rookery Bay has experienced similar impacts to natural resources resulting in this case from the
dry- season deficit of freshwater discharge. This diversion project will result in similar
improvements to coastal/marine resources resulting from the increase of freshwater flow by
about 19 percent. Furthermore, as estuaries and seagrass beds provide habitat for a variety of
fish and invertebrate species, the diversion of freshwater discharge will in turn result in marine
life habitat improvements in both bay systems.
How will community resilience be enhanced?
Improving the seasonal excess freshwater flow to Naples Bay and the deficiency in Rookery Bay
will improve the resilience of these two important estuary systems in Collier County, both of
Packet Page -2077-
2/26/2013 16.F.5.
which are currently threatened by seasonal variability in freshwater discharges.
Over the past 50 years, Naples Bay has experienced significant development which has altered
not only the direct shorelines and natural resources within the bay, but also the entire watershed
through dredge -and -fill operations and channelization projects. These projects have expanded the
watershed of Naples Bay from what was once about 10 square miles to about 120 square miles
today. The 10 percent reduction of freshwater flows anticipated by this project will improve
freshwater discharges and therefore also the salinity and nutrient load ultimately allowing for
further restoration of natural resources in Naples Bay. This diversion will improve seasonal
freshwater shortages to the Rookery Bay Estuary by 19 percent.
As described here, the diversion of freshwater discharge from Naples Bay to Rookery Bay will
result in regained and repaired habitat, improved salinity levels and will improve the health,
balance and resilience of the estuaries.
Additional Justification:
Construction of the Golden Gate Main Canal significantly increased the size of the watershed
draining to Naples Bay and reduced the size of the watershed flowing to Rookery Bay. As a
result, Naples Bay receives significantly too much water and Rookery Bay receives too little
water, thus negatively affecting both receiving estuary systems. Additionally, the reduction of
stormwater runoff to the south has decreased wetland hydroperiods in areas where sheetflow
used to occur. This project is part of a larger program to restore the hydrology of the entire Belle
Meade Flowway which extends from the Golden Gate Main Canal north of I -75 in the north,
U.S. 41 and the Ten Thousand Islands in the south, and reaching from the Picayune Strand
CERP Restoration Project to the east and urban development and C.R. 951 to the west. The
entire Belle Meade Flowway encompasses several thousand acres of wildlife habitat and
wetlands that have been severely altered by development, as well as a canal system sending
water west to Naples Bay (Attachment 4).
There are several conceptual plans for this project which provide for alternative development
scenarios. The construction of the planned Wilson Blvd Extension could provide for alternative
land acquisition scenarios in which the diversion canal could be located along Wilson Blvd and
funded through the road construction. Another alternative scenario includes dedicating the
flowway through the development process in the lands south of the spreader swale. This would
subject the dedication of the flowway to sporadic or delayed development of the area. The
proposed project includes increased land acquisition budgeting to account for a scenario in which
acquisition is required for flowway easements in addition to the diversion canal and spreader
swale however, conditions and permitting may require a combination of project scenarios.
Though Collier County is outside the study area of the CHNEP CCMP, this project would
support several of the quantifiable objectives and priority actions identified in the plan (pg 86),
including:
• HA -2... [to] restore, enhance and improve where practical historic watershed boundaries

• HA -G: Reestablish hydrologic watersheds to contribute flows to their historic receiving

Name of Project: Henderson Creek Diversion Pump Station
Org and Rank: Collier
County, Florida
Project Description: This project would utilize a 100 cfs pump station constructed near the new
GG -3 structure to divert water from the Golden Gate Main Canal to the Henderson Creek Canal.
Diverted water will move south through a new 5200 LF dredged canal, 30' wide and 10' deep
and water will flow into Henderson Creek through an existing box culvert under I -75. The
project is predicted to reduce the volume of discharge to Naples Bay by about 10 percent. The
project will also increase the volume of water entering Rookery Bay by about 33 percent.

Quantify Environmental Results and How to Measure Them: Results will be measured by
volume of freshwater diverted from Golden Gate Main Canal to the Henderson Creek Canal.
Economic Benefits (including ecosystem services):
The project will improve water quantity conditions to both the Naples Bay and Rookery Bay.
While the value of the seasonal changes in discharge rates is difficult to quantify, the ecosystem
service value can be estimated of the areas which will experience improvements. Based on the
ecosystem service values derived in Costanza et. Al. (1997), this project will benefit areas with
combined ecosystem services values of approximately $19,000,000 per year (Attachment 3).
This figure represents the value of services provided by the surface area of the estuaries which
will receive a benefit as a result of the diversion. Additional economic benefits will be realized
as a result of the future seagrass restoration projects which will only be possible once freshwater
discharge imbalances have been improved.
Estimated number of Jobs Created or Preserved: 57 (Estimate based on 1 job per $100,000)
How much Habitat will be restored and conserved ?:
Freshwater flow will be improved in both Naples Bay and Rookery Bay as a result of this
project. Naples Bay has a surface area of about 1066 -acres and Rookery Bay encompasses a
surface area of about 1,034- acres.
Since the 1950's, Naples Bay has seen a reduction in seagrass bed acreage from about 68 -acres
to about 4 -acres today. These remaining seagrass beds will experience restored water quantity
and quality through restored freshwater discharge rates to Naples Bay which will allow for
Packet Page -2083-
2/26/2013 161 .5.
significant increases in seagrass bed acreage through future restoration projects anticipated by
the City of Naples and the South Florida Water Management District.
Quantify pollutant reductions:
This project is primarily designed for water quantity benefits. Pollutant loads from Golden Gate
Canal into Naples Bay will be reduced insomuch as freshwater flows are reduced. However,
increased freshwater discharges may increase pollutant load to Rookery Bay.

What living coastal/marine resources will be improved and by how much ?:
In Naples Bay, the reduction in freshwater flow will improve habitat for seagrasses, improve
salinity and reduce nutrient levels in the freshwater flowing from the Golden Gate Canal. These
improvements will be enhanced in proportion to the freshwater flow reduction of 10 percent.
Rookery Bay has experienced similar impacts to natural resources resulting from dry- season
freshwater discharge deficits. This diversion project will result in similar improvements to
coastal /marine resources resulting from the increase of freshwater flow by about 33 percent.
Furthermore, as estuaries and seagrass beds provide habitat for a variety of fish and invertebrate
species, the diversion of freshwater discharge will in turn result in marine life habitat
improvements in both bay systems.
How will community resilience be enhanced
Improving the seasonal excess freshwater flow to Naples Bay and the deficiency in Rookery Bay
will improve the resilience of these two important estuary systems in Collier County, both of
which are currently threatened by seasonal variability in freshwater discharges.
Over the past 50 years, Naples Bay has experienced significant development which has altered
not only the direct shorelines and natural resources within the bay, but also the entire watershed
through dredge -and -fill operations and channelization projects. These projects have expanded the
watershed of Naples Bay from what was once about 10 square miles to about 120 square miles
today. The 10 percent reduction of freshwater flows anticipated by this project will improve
freshwater discharges, and therefore also the salinity and nutrient load. This will ultimately
allow for further restoration of natural resources in Naples Bay. This diversion will improve
seasonal freshwater shortages to the Rookery Bay Estuary by 33 percent. Furthermore, this
project provides additional water to Henderson Creek which may be available to augment future
water supply needs for the Marco Island Water Treatment Plant.
As described here, the diversion of freshwater discharge from Naples Bay to Rookery Bay will
result in regained and repaired habitat, improved salinity levels, and will improve the health,
balance and resilience of the estuaries.
Additional Justification:
Packet Page -2084-
2/26/2013 16.F.5.
Construction of the Golden Gate Main Canal significantly increased the size of the watershed
draining to Naples Bay and reduced the size of the watershed draining to Rookery Bay. As a
result, Naples Bay receives significantly too much freshwater and the Henderson Creek
Watershed and the Rookery Bay estuary are starved of freshwater; these negative affects to both
receiving water estuary systems will likely only worsen as Collier County continues to grow.
This project would improve the freshwater discharges to both Naples Bay and Rookery Bay.
One of the ecosystems most severely impacted by the freshwater flowing into Naples Bay
includes oysters and seagrasses. Most of the seagrasses that once existed in Naples Bay are now
gone. While there are in fact some areas of Naples Bay where seagrasses can be found, the
seasonal pattern of excessive freshwater flows to Naples Bay has hindered the expansion and
restoration of seagrass beds as natural salinity patterns are critical to restoring estuarine habitat.
Reducing those freshwater flows to the Bay will improve conditions which will allow seagrasses
to recover and also allow for supplemental plantings to be attempted.
Though Collier County is outside the study area of the CHNEP CCMP, this project would
support several of the quantifiable objectives and priority actions identified in the plan (pg 86),
including:
• HA -2... [to] restore, enhance and improve where practical historic watershed boundaries
and natural hydrologies...
• HA -G: Reestablish hydrologic watersheds to contribute flows to their historic receiving
water bodies.
• HA -J: Build and restore water conveyances to have shallow, broad, vegetated and
serpentine components that also restore floodplains.

RESTORE Act Ecosystem Restoration Project Proposals
for consideration in the Gulf Coast Ecosystem Restoration Council's Comprehensive Plan
2012
Contact Information: Jerry Kurtz, P.E., Principal Project
Date of Submittal: November
Manager
5, 2012
Name of Project: South I -75 Canal Spreader Swale
Org and Rank: Collier
County, lorida
Project Description: This project would include the design and construction of a 50 cfs pump
station to pump water from the interconnected I -75 canal network into a feeder channel.
Subsequently, a spreader swale would be constructed to facilitate movement of water out of the
canals that parallel I -75 and direct the water south via overland flow. This project focuses on
rehydration of wetland areas in the Rookery Bay Watershed, the Southern Belle Meade area, and
northern portion of the Picayune Strand State Forest.
Project Location: Collier County (Attachment 1).
Responsible Party: Collier
Partners: Collier County, SFWMD, USACE
County Natural Resources
Department

Quantify Environmental Results and How to Measure Them:
Results will be measured in increased freshwater discharge into Rookery Bay.
Economic Benefits (including ecosystem services):
This project will result in increases in the hydrology of wetland areas in the Rookery Bay
Watershed including the Southern Belle Meade area and northern portions of the Picayune
Strand State Forest. Based on the ecosystem service values derived in Costanza et. Al. (1996),
this project will benefit areas with combined ecosystem services values of over $100,000,000 per
year (Attachment 3).
Estimated number of Jobs Created or Preserved: 31 (estimate based on 1 job per $100,000)
How much Habitat will be restored and conserved?
The project will restore wetlands in the South Belle Meade Area and northern portion of the
Picayune Strand State Forest within the Rookery Bay watershed, approximately 27,000 acres.
The project will also restore timing and discharge rates of freshwater flows into Rookery Bay
which has a surface area of 1034- acres.
Quantify pollutant reductions:
The project provides water quality treatment to the flows diverted from the I -75 canal to the
spreader swale. The first calculation below assumes some limited amount of treatment occurs
during the diversion process due to filtering. Some water is assumed to be lost due to

infiltration/ET. The second calculation estimates treatment as the additional water moves
through the system.

What living coastal/marine resources will be improved and by how much ?:
The construction of the canals changed the pattern of discharge to the estuary through a dry
season deficit and wet season surplus, resulting in excessive fresh water discharge and thus
ultimately affecting the salinity of the Naples Bay estuaries. This project will improve wetland
hydrology and restore through slow release diverting water to the Picayune Strand State Forest.
The project would result in improvements in water quality, wetland hydrology/habitat and timing
of discharges to the Rookery Bay estuary.
How will community resilience be enhanced?
Improving the timing and duration of freshwater discharges to Rookery Bay will enhance the
resilience of the Bay which is currently threatened by seasonal variability in freshwater
discharges, namely freshwater deficits during the dry season.
Additional Justification:
The Rookery Bay watershed has decreased by about 100 sq. mi. due to construction of canals. As
a result, the hydrology of remaining wetlands has changed by shorter hydro -period and less
water stored, negatively affecting native wildlife and fauna. This project would redistribute and
alter the timing of freshwater discharges.
This project is part of a larger program to restore the hydrology of the entire Belle Meade
Flowway which extends from the Golden Gate Main Canal north of I -75 in the north, U.S. 41
and the Ten Thousand Islands in the south, and reaching from the Picayune Strand CERP
Restoration Project to the east and urban development and C.R. 951 to the west. The entire Belle
Meade Flowway encompasses several thousand acres of wildlife habitat and wetlands that have
been severely altered by development, as well as a canal system sending water west to Naples
Bay (Attachment 5).
Though Collier County is outside the study area of the CHNEP CCMP, this project would
support several of the quantifiable objectives and priority actions identified in the plan (pg 86),
including:
• HA -2... [to] restore, enhance and improve where practical historic watershed boundaries
and natural hydrologies...
HA -G: Reestablish hydrologic watersheds to contribute flows to their historic receivi

water bodies.
• HA -J: Build and restore water conveyances to have shallow, broad, vegetated and
serpentine components that also restore floodplains.
