1. Collier Creek Modeling - Recommendations
Stephen Keehn, Tara Brenner and Joao Dobrochinski of APTIM presented a PowerPoint
“Navigation Optimization and Sediment Management at Collier Creek Fl.”
Mr. Brenner noted the work on the Creek began in 2015 when a feasibility study was developed
to address the sediment infill and navigation issues with the area. In 2017 the modeling study
began which led to the November 2018 draft plan.
Mr. Dobrochinski provided an overview of the modeling highlighting:
• The area is subject to a large volume of boat traffic with a series of accidents reported.
• The Creek was dredged in 2012, 2016 and 2018 and the area accretes new sand in a short
term after the work and the goal of the plan is to significantly lengthen the dredging cycle.
• Field measurements were utilized to develop the model which showed incoming tides
driving the conditions of the channel.
• Based on the model, numerous solutions were developed and tested to determine the most
beneficial long term solution to the problem.
• The most advantageous option is use of a combination of 2 structures of various locations
and length (“Alternative 13/14”) which would potentially lengthen the dredge cycle to 9.5
years.
Mr. Keehn reported:
• The alternatives propose construction of a groin 400 feet west of the existing jetty and a
100 foot long terminal jetty on the west side of the channel.
• Included in the proposal is dredging the channel to an additional width and moving it
easterly incorporating a new bend.
• The terminal jetty option is still under review however the following cost estimates have
been developed ($2,197,700 with the jetty and $2,057,300 without the jetty).

• The cost of the existing maintenance has been $670,000 every two years however the
alternatives under consideration would yield maintenance costs of $729,000 over 8 years.
• An assessment of a 16 year period yields a $2.8M cost to the County with the solutions in
place versus the $5.3M if the current activity continues.
• The estimated construction timeline is 150 – 180 days and there has been communications
with the Florida Department of Environmental Conservation who is amenable to the
concept but wants to ensure no “net sand loss” on State lands.
• The alternatives will continue to be refined including developing a sediment management
program.
Mr. McAlpin reported there will be dialogue with representatives of Hideaway Beach Taxing
District and the City of Marco Island on the plan and some existing permits may require
modification.
He requested the Committee endorse the conceptual plan so the work necessary to develop a
comprehensive plan may move forward. The work may potentially begin in one year.
Speaker
Ben Farnsworth, Villa DeMarco West supports the project, however noted consideration may
want to be given to minor modifications to the proposed channel such as limiting the bend.
Mr. McAlpin reported the current proposed locations is favored however he will continue to work
with Mr. Farnsworth in an attempt to address any issues.
Ms. Roddy moved for Staff to move forward with the plan as presented and work with the
various agencies, as necessary, to develop the solutions required to develop the final
management plan for the Creek. Second by Mr. James Burke. Carried unanimously 7 – 0.
Mr. McAlpin reported the Committee will be updated on the progress of the study.
Mr. McCann left the meeting at 2:10 pm
2. Marco Island Regrade – Update
Mr. McAlpin reported:
• The project to re-grade the Marco Island beaches to eliminate ponding of water was
approved by the Board of County Commissioners at the end of January and work is
underway.
• The work is divided into 4 areas of dredge and fill activities.
• Issues that arose with the Burrowing Owl and Gopher Tortoises in the area were addressed
and the project is anticipated to be completed by April 15th.
Speaker
Deborah Devries requested the County consider reinstalling the boulders that were displaced off
the jetty during Hurricane Irma.
Mr. McAlpin reported the boulders may be repositioned following completion of the re-grading
project and they aren’t causing any negative impacts to the area at this point in time.

subject Review of Collier County Water Quality Data
Introduction
Under a sub-consultant agreement with Taylor Engineering (Contract Number C2018-052), ESA was contracted in
support of evaluating the Florida Department of Environmental Protection’s (FDEP’s) latest – at the time of the
execution of the agreement - Comprehensive Verified List (November 2018) of water quality impairments for
waterbodies within Collier County. Within the Verified Impaired List, there are numerous WBID-impairment
combinations for water bodies, including impairments for dissolved oxygen, nutrients in terms of both Trophic
State Index (TSI), chlorophyll-a, and fecal coliform bacteria. Prior to commencing with further steps such as the
development of Total Maximum Daily Loads (TMDLs) and the development of Basin Management Action Plans
(BMAPs) Collier County wishes to review those WBID-impairment combinations that involve water bodies within
the County. In addition, there are a number of TMDLs for waterbodies in Collier County, some of which are based
on water quality criteria that are no longer used by FDEP to determine impairment. In addition to the concerns with
problematic impairment determinations, the load reductions called for in TMDLs can directly impact Collier
County’s budget for capital improvement projects, as TMDLs lead, by rule, to BMAPs, which are meant to be “self-
implementing” through the National Pollutant Discharge Elimination System (NPDES) permitting process, and the
need for the Collier County’s to update its NPDES permit with FDEP.
In October 2018, ESA submitted a draft technical memorandum which summarized the efforts completed for many
of the assigned tasks including:
•Review of the latest version (at that time) of the Comprehensive Verified Impaired list (November 2018)
produced by the Florida Department of Environmental Protection (FDEP).
•Review of the data sets used by FDEP to create its most recent (at that time) Comprehensive Verified
Impaired List
•A review of the data used by FDEP to create Numeric Nutrient Concentration (NNC) criteria for coastal
waterbodies in Collier County

Review of Collier County Water Quality Data

• A comparison of recent water quality data against the NNC criteria used for Collier County’s coastal
waterbodies
Subsequent to the draft memorandum, ESA presented the preliminary findings to a local peer review group as
selected by Collier County on November 29, 2018. ESA incorporated the technical comments and in
coordination with Collier County presented those findings related to the above-described review of impairment
determinations and TMDL assessments to senior-level FDEP staff on January 16, 2019. Efforts were made to
include participation by FDEP staff in management positions, as well as technical staff, so that any problematic
impairment determinations or concerns about NNC criteria or approved TMDLs would be discussed at a
management level that would allow FDEP to direct staff to appropriate respond to any legitimate concerns raised
by Collier County. This document updates the results and recommendations presented in the November 2018
draft technical memorandum, and also updates those findings through the incorporation of technical comments
and discussions with Collier County and FDEP staff. Additionally, this document summarizes the relevant
discussion items and recommendations which resulted from the January 2019 meeting with FDEP staff
specifically as it relates to recommendations to resolve identified issues that may interfere with the design and
permitting stages of the Collier County Watershed Improvement Project (CCWIP).
Special considerations
It is important to note that FDEP has modified their guidance criteria over time, and has also modified the
techniques used to group stations together into distinct geographic regions. In prior years, FDEP determined
marine waterbodies were impaired for levels of dissolved oxygen (DO) based on the standard that average values
had to exceed 5 mg / liter, and no value could fall below 4 mg / liter. This historic DO criteria, no longer used by
FDEP to determine impairment status, is the basis for the Total Maximum Daily Load (TMDL) for the Gordon
River Extension. More recently, FDEP’s criteria for DO (FAC 62-302.533) has been (for marine systems) that no
more than 10 percent of samples should have minimum DO levels below 42 percent saturation. This more recent
DO criteria is a more realistic standard for waterbodies located in areas where their watersheds have substantial
amounts of wetlands. Similarly, the criteria for pathogens had previously been based on the abundance of fecal
coliform bacteria. Currently, FDEP’s uses E. coli bacteria as the indicator of impairment in freshwater systems,
and enterococci bacteria for Class III marine waters. For Class II waters – those where the designated use is
shellfish harvesting – the indicators of impairment are now both fecal coliform bacteria and enterococci bacteria.
While surface water criteria updates in the past ten years have resulted in more appropriate measures to determine
a surface waterbody’s ability to meet its identified designated use, in many cases existing management action
plans are based on criteria that may reflect unrealistic expectations (e.g., 2008 TMDL for the Gordon River
Extension).
In addition to the issue of differences in impairment criteria, the geographic areas over which water quality are
collected and analyzed and compared to criteria has changed over time. Recently, FDEP has developed NNC
criteria for coastal waterbodies that were developed from data sets from larger areas termed Estuarine Nutrient
Regions (ENRs). For the central portion of Collier County’s coastline, there are five main ENRs: 1) ENRE1 for
the Tidal Cocohatchee River, 2) ENRE2 for Collier Inshore, 3) ENRE3 for Rookery Bay / Marco Island, 4)
ENRE4 for Naples Bay, and 5) ENRE8 for the Blackwater River (Figure 1).

Figure 1 – Geographic boundaries of Estuarine Nutrient Regions (ENRs) developed by FDEP.
In the northern portion of Collier County’s shoreline, the ENR for Little Hickory Bay (ENR11) extends from
Bonita Beach Road south to Wiggins Pass. The ENR for Water Turkey Bay (ENRD12) extends from Wiggins
Pass down to Vanderbilt Beach Road. The ENR for Clam Bay (ENRJ1) includes Upper, Inner and Outer Clam
Bay, and the ENR for Moorings Bay (ENRD13) extends from Vanderbilt Beach Road down to Banyan
Boulevard. Each of the individual ENRs has its own NNC criteria, developed for each system. The NNC criteria
for Clam Bay is the only one where nutrient concentrations take into account salinity, the NNC for the other
ENRs are single concentrations for TN, TP and chlorophyll-a.
One of the most notable discrepancies identified since the implementation of the ENR derived NNC, is that the
criteria are not always implemented over the same spatial area that was used to develop the criteria. For
example, the ENR for Rookery Bay / Marco Island contains three separate WBIDs: Marco Island, Marco Island
(South Segment) and Rookery Bay (Figure 2). The prior WBID for “Rookery Bay” extended farther to the east,
compared to the boundaries for the ENR for Rookery Bay and Marco Island. Also, the waters of Marco Island

and areas south of Marco Island (down to Cape Romano) are now grouped together with Rookery Bay as a single
ENR. This change means that water quality within the canal systems of Marco Island, which might be expected
to be influenced by stressors different than those from the more natural conditions of Rookery Bay, were grouped
together into one geographic region for the development of the NNC criteria. In essence, an individual WBID’s
water quality is compared to the water quality for a larger areas. This approach can result in a finding of
impairment for a waterbody, even if that waterbody’s water quality was not degrading over time.

Data sources and analyses conducted
Data sources were restricted, as much as possible, to those that would be used by FDEP in its efforts to determine
the impairment status of Collier County’s waterbodies. The boundaries of WBIDs and ENRs were retrieved from
FDEP as distinct GIS files, as were station locations and the water quality data analyzed in this draft technical
memorandum. Water quality data and station locations were retrieved from the Impaired Waters Rule (IWR) Run
55, which represented the most recent comprehensive collection of water quality FDEP had available at the time.
Surface water quality criteria were derived from Florida Administrative Code (FAC) 62-302, and the analyses
performed were conducted consistent with guidance included in both FAC 62-302 and 62-303 as well as direct
communication with FDEP.
FDEP’s NNC criteria are based on requirements that water samples are taken throughout the year, with a
requirement that samples include those from Southwest Florida’s typical wet season. The appropriate surface
water criteria were applied for individual WBIDs within an estuarine nutrient segment as indicated in 62-302.532
(FAC) as directed by FDEP staff in Tallahassee (Kevin O’Donnell, email communication). For the majority of
ENRs, compliance with NNC criteria is based on a determination of whether or not annual geometric means
(AGMs) exceed values for chlorophyll-a, Total Nitrogen (TN) and Total Phosphorus (TP). A waterbody is
deemed in violation of NNC criteria if it exceeds those guidance criteria more than once in a rolling three-year
period. Therefore, a waterbody that exceeds NNC criteria only once in a three-year period would not be
considered impaired. Nutrient impairments for both Clam Bay and Moorings Bay ENRs are determined based
upon whether more than ten percent of the samples in the most recent seven-year period exceed the NNC criteria.
It is important to note that for the coastal waters of Collier County, from Naples Bay to Rookery Bay and the Ten
Thousand Islands, FDEP (2011) concluded that “Due to the relatively low nutrient and chlorophyll a levels
observed, the lack of long-term increasing trends in nutrient and chlorophyll a concentrations, the lack of
widespread biological impacts associated with nutrients, and the large number of natural conservation lands in the
region, the proposed nutrient criteria were developed to maintain existing conditions, which are supportive of
healthy, well-balanced populations of flora and fauna.” In other words, FDEP concluded that water quality was
not a concern for these systems, based on data collected between 1999 and 2007. Therefore, the intent of the
NNC criteria is to determine if water quality conditions in recent years show evidence of degradation from the
1999 to 2007 conditions; they are, in effect, “hold the line” criteria.
Findings
On November 4, 2018, FDEP released a draft verified impaired list for Group 1, Cycle 4 which incorporated
recently adopted criteria (including DO, bacteria and NNC). Prior to the adoption by FDEP of revised criteria
(for marine waters) for DO and nutrients, waterbodies would be declared impaired based on the DO criteria of 4
mg / liter, and also on the application of screening-level criteria for chlorophyll-a of 11 µg / liter. This was the
first reporting which provided impairment designations using revised criteria. In its draft list of impaired
waterbodies from November 4, 2018, FDEP identified the following coastal and estuarine Collier County WBIDs
as impaired (Tables 1 and 2).

Of the impairments listed in Table 1, multiple waterbodies are impaired for bacteria related criteria (enterococci,
fecal coliform bacteria); including Gordon River (Marine Segment), Haldeman Creek (Lower) and Rock Creek
for the revised Enterococci criteria. The Cocohatchee River was identified as impaired for copper, whose criteria
has remained the same over time. However, the criteria for DO and nutrients have both changed over time. The
Cocohatchee River and Gordon River (Marine Segment) were both identified for depressed DO levels, using the
42 percent saturation criterion. In regards to nutrient impairments (Table 2), several waterbodies were identified
as impaired for other water quality parameters, including the Cocohatchee River, Gordon River (Marine
Segment), Moorings Bay, Gulf of Mexico (Collier County; Marco Island) and Naples Bay (Coastal Segment).
The implementation of revised criteria resulted in some important differences in regards to previously identified
impairments in the Collier County estuarine systems. Previously, Rookery Bay and Marco Island were identified
as impaired for nutrients. Under the revised criteria, neither system is listed as impaired. In contrast, the
Cocohatchee River, Naples Bay and Moorings have now been identified as having nutrient-related impairments.
It should be noted that the Gordon River Extension does not show up on FDEP’s November 2018 comprehensive
verified impaired list, because it has an adopted TMDL (FDEP 2008). However, that TMDL is based on the prior
criterion for DO, not the more recently adopted one.
Specific to the development of the revised NNC for the ENRs within the Tidal Caloosahatchee/ Ten Thousand
Island area, the water quality dataset used by FDEP was heavily reliant on an extensive water quality monitoring
programs conducted by Florida International University (FIU) which was supported by the South Florida Water

Management District (SFWMD; Figure 3). This large-scale sampling effort covered an area stretching from
Biscayne Bay down to Key West, across the open waters of Florida Bay, and up to the Caloosahatchee River.
The data collected and analyzed by FIU were then used to determine the water quality conditions during the
period of 1999 to 2007, after which the extensive monitoring program was reduced in both frequency and
geographic extent.
Figure 3 – FIU monitoring stations during 1999 to 2007 used for ENR NNC criteria development.
For Collier County’s estuaries, the FIU data was interpreted by FDEP as there was no need to reduce nutrient
loads and improve water quality. Instead, the water quality data set was used to derive – via NNC - a baseline
condition to maintain. As such, the NNC criteria were mostly set as the 80th percentile value for data collected by
FIU (FDEP 2011). While the criteria were developed for the ENR, the surface water criteria are applied to those
WBIDs contained within the ENR boundary as directed by FDEP (see Figure 2). Therefore, impairment would
occur if the annual geometric mean (AGM) for TN, TP or chlorophyll-a was to be higher than the 80th percentile
value from the 1999 to 2007 FIU data base for a given WBID within an ENR. If AGM values exceeded NNC
criteria more than once in a three-year period, the WBID would be considered to be in violation of NNC criteria
(FDEP 2011).
With this background, and using the data sources outlined above, ESA performed an independent analysis of the
impairment designation of the coastal/estuarine WBIDs in Collier County. Since the period of 1999 to 2007 was
viewed as the “reference “period for setting NNC criteria, only data collected after 2007 was used in the analysis
of NNC criteria developed for this report. Table 3 summarizes the determinations of impairment found by ESA

The Cocohatchee River waterbody (WBID 3259A) is comprised of three ENRs: Tidal Cocohatchee River
(ENRE1), Little Hickory Bay (ENRD11) and Water Turkey Bay (ENRD12; Figure 4). Therefore, water quality
impairment assessments are performed at the ENR level within the WBID. ESA’s independent analysis
concurred with FDEP that the Tidal Cocohatchee region was impaired for chlorophyll-a and total nitrogen and
Water Turkey Bay is impaired for chlorophyll-a (Figures 5 and 6). As of March 2019, a TMDL has not been
drafted or adopted for the Tidal Cocohatchee River, which has been identified as a “Medium” priority for TMDL
development.

assessments are performed at the ENR level within the WBID. ESAs independent analysis identified the
Blackwater River as impaired for TN, the Coastal Transition Zone as impaired for TP and the Gulf Islands as
impaired for TN and Chlorophyll-a (Figures 8 and 9). FDEP did not include the Ten Thousands Islands on the
November 2018 impairment list, perhaps due to the limited number of years with sufficient data for comparison
with the criteria. As of March 2019, a TMDL has not been drafted or adopted for the Ten Thousand Islands,
which has been identified as a “Medium” priority for TMDL development.

Naples Bay (WBID 3278R4)
The Naples Bay waterbody (WBID 3278R4) matches the spatial extent of the Naples Bay ENR (ENRE4; Figure
10). ESA’s independent analysis concurred with FDEP that Naples Bay was impaired for chlorophyll-a but not
for nutrients (Figure 11). Typically, elevated phytoplankton production (chlorophyll-a) is associated with
excessive nutrient loading. In this case, nutrients were not identified as problematic. This finding is problematic
in terms of management guidance, and suggests that either the chlorophyll-a criterion is too stringent, or the
nutrient criteria are too lenient. As of March 2019, a TMDL has not been drafted or adopted for Naples Bay,
which has been identified as a “Medium” priority for TMDL development. Prior to TMDL development, the
interaction between nutrients and chlorophyll-a should be investigated further. Additionally, an evaluation to
determine whether current chlorophyll-a concentrations are negatively impacting the ecological health of Naples
Bay should be completed. An assessment of nutrients, chlorophyll-a concentration, DO concentrations and water
clarity would assist in ascertaining whether the established TN and TP criteria are effectively protecting the water
resources.

Clam Bay (WBID 3278Q1)
The Clam Bay waterbody (WBID 3278Q1) corresponds with the Clam Bay (ENRJ1) ENR (Figure 12). Clam Bay
is unique among Collier County’s coastal waterbodies, as the nutrient criteria are normalized for salinity (FAC
62-302.532). This permits a range of acceptable nutrient concentrations based upon the salinity at the time of
sampling, as prior work conducted by both ESA and FDEP has found that higher salinities are typically
associated with lower nutrient concentrations while locations or times (or years) with a greater freshwater
influence typically have higher nutrient concentrations, even in “pristine” or reference WBIDs. ES’s independent

analysis identified Clam Bay as impaired for Total Phosphorus, while FDEP did not identify such an impairment
due to insufficient data. This would suggest that water quality data from Clam Bay are not being uploaded to
FDEP in their entirety.
Clam Bay data, as available within FDEP IWR Run 55, were compares to the salinity-normalized NNC criteria
for the period of January 1, 2009 to June 30, 2017 to be consistent with the time period examined for other
waterbodies. For Clam Bay, only two sampling events were included after January 2015, although earlier years
had sufficient data to determine compliance with NNC criteria. The results of the analysis indicate that Clam
Bay would be identified as “impaired” for total phosphorus, as 12 percent of the event samples exceeded the
criteria. For TN, only four percent of the event samples exceeded the criteria thus meeting the water quality
expectations. There are no criteria for chlorophyll-a in Clam Bay.

The Moorings Bay waterbody (WBID 3278P) corresponds with the Moorings Bay ENR (ENRD13; Figure 13).
The NNC for Moorings Bay is different from the other waterbodies, as chlorophyll-a is evaluated using AGM but
both TN and TP are assessed by whether more than 10 percent of samples exceed the numeric criteria (FAC 62-
302.532). ESA’s independent analysis was consistent with FDEPs determination that Moorings Bay as impaired
for TP but not TN or Chlorophyll-a (Figures 14 and 15). The results of the analysis identified 19 percent of the
event samples exceeded the TP criteria. For TN, only eight percent of the event samples exceeded the criteria
thus meeting the water quality expectations. As of March 2019, a TMDL has not been drafted or adopted for
Moorings Bay and has been identified as a “Medium” priority for TMDL development.

Rookery Bay/Marco Island
Collier County is proceeding with a large-scale hydrologic restoration project within the Rookery Bay watershed,
which has been extensively altered through complex canal networks including water control structures (Atkins
2011). As a result of these alterations, Rookery Bay’s historical watershed has been reduced by approximately 80
sq. miles (Interflow Engineering, Inc. and Taylor Engineering 2014). In contrast, the Naples Bay watershed has
been enlarged by approximately 90 sq. miles (Cardno 2015). These altered hydrologic conditions have negatively
impacted the ecology of both bays, as well as the watersheds of both systems (SWFWMD 2007, Atkins 2011).
Numerous studies have been completed to identify potential hydrologic restoration projects to restore the
hydrologic balance between the two watersheds. One of the most recent and comprehensive reports, the Collier
County Watershed Improvement Plan (CCWIP) includes project components designed to improve the water
quality of both Naples Bay and Rookery Bay, as well as to rehydrate the ditched and drained portions of the
Rookery Bay watershed known as the Belle Meade region. These proposed projects are consistent with
RESTORE and the County’s Comprehensive Management Plan.
The CCWIP restoration project is designed to redirect water from the Golden Gate Canal system into the Belle
Meade region, allowing for the reestablishment of some portion of the historical quantity and quality of
freshwater inflows into both Naples Bay and Rookery Bay.
In ESA’s experience, previously proposed hydrologic modification projects have been delayed or cancelled due
to water quality related concerns raised in response to the addition of freshwater inflows to an “impaired”
waterbody. As part of the permit process, the regulatory agency is responsible for reviewing the water quality
status of both the source and receiving water. For example, in the late 2000’s, FDEP developed a comprehensive
plan to remove the Rodman Dam on the Ocklawaha River. While this would restore an obvious hydrologic
alteration, regulatory and scientific staff with the St. Johns River Water Management District determined that
removal of the dam would eliminate the backwater effect (i.e., Rodman Reservoir) which would result in a loss of
Hydrilla in the areas upstream of the dam. This was determined to likely increase downstream loads of nitrate
from the nutrient-enriched waters of Silver Spring, and these increased nitrate loads would likely manifest
themselves as an increased nutrient load to the Lower St. Johns River. As the Lower St. Johns River had a
nutrient TMDL, regulatory staff with the St. Johns River Water Management District did not feel that they had
the regulatory flexibility to sign off on a permit for a project that would likely increase nutrient loads to a
waterbody with an existing nutrient TMDL.
In more recent years, it appears that FDEP and the various water management districts have established
mechanisms which allow for hydrologic restoration projects that would increase nutrient loads to nutrient-
impaired waterbodies (Drew Bartlett, personal communication). More recently, the Southwest Florida Water
Management District initially denied Sarasota County’s proposed Phase II efforts for the Dona Bay hydrologic
restoration project during the pre-application phase. The denial was due to concerns related to the likelihood of
increasing nutrient loads to a downstream nutrient-impaired waterbody, the tidal Myakka River. At the request of
Sarasota County, additional work was performed by ESA to clarify the impairment status of the Myakka River
WBID, and to quantify the expected changes in nutrient loads and nutrient concentrations likely to occur with
Phase II efforts. This information was presented to regulatory staff, and resulted in a change so that the project
received permits from the Southwest Florida Water Management District, as well as financial support via the
District’s Cooperative Funding Program. In light of the various challenges that have faced hydrologic restoration
projects, ESA completed a more extensive evaluation of the method used to develop the NNC criteria, the water

quality status and potential implications for the Belle Meade restoration project that could result in a potential
delay in the regulatory review of the proposed CCWIP.
Impairment Status
ESA performed an independent analysis of the impairment designation of the Rookery Bay/Marco Island ENR
which includes three WBIDs: Rookery Bay, Marco Island (South Segment) and Marco Island (Figure 18). The
Rookery Bay and Marco Island WBIDs had sufficient annual exceedances of TN to be impaired (Figures 19 to
21). Insufficient chlorophyll-a data were available to calculated AGM for Rookery Bay, however, subsequent
conversations with FDEP indicated that the next IWR Run (Run 56) will contain sufficient data. The Marco
Island (South Segment) WBID was not identified as impaired. FDEP did not classify any of the Rookery
Bay/Marco Island ENR WBIDs as impaired. Rookery Bay was placed on the Study List due to the impending
restoration project.
Staff from Collier County, Taylor Engineering and ESA met with senior FDEP staff in January 2019 to discuss
the implications of preliminary impairment results on the fate of the Belle Meade hydrologic restoration project.
Overall, FDEP staff were emphatic that a downstream impairment (Rookery Bay) declaration does not
categorically result in the termination of the proposed project. It was recommended that Collier County
incorporate FDEP staff in future meetings with SFWMD regulatory personnel to assist in providing sufficient
documentation during the permitting process. Additionally, FDEP proposed that in lieu of the traditional
assessment category which denotes the future development of a TMDL (Category 5), Rookery Bay could be
classified as assessment category 4e. A 4e plan is available to impaired WBIDs in which a planned or on-going
restoration activity is underway which is anticipated to impact water quality. Waterbodies classified for 4e
development require documentation which support the anticipated water quality response to the proposed project
and delays impairment assessment to the subsequent cycle. At this time, FDEP has developed 4e documentation
to support placing Rookery Bay in assessment category 4e, which should relieve Collier County – for now – of
any concerns about the impacts of regulatory water quality programs to delay the hydrologic restoration efforts
contained within the CCWIP.

Issues of Concern Related to NNC Criteria Development
As described above, the NNC criteria for Collier County ENRs were derived from the FIU ambient monitoring
program. A comparison of the existing monitoring efforts (2008-2018) as available in IWR Run 55 and the FIU
monitoring program (1997-2007) was completed to compare the spatial and temporal sampling efforts of both
efforts. For the Rookery Bay/Marco Island ENR, FIU established eleven water quality monitoring sites which
were used in the development of the NNC criteria (Figure 22). Over time, the FIU monitoring program changed,
reducing the spatial and temporal sampling effort. Currently, there are only four actively sampled locations that
are in the same locations as the FIU stations that were originally distributed throughout the Rookery Bay/Marco
Island ENR. Consequently, the existing monitoring programs, operated by FDEP, SFWMD and the City of
Marco Island, vary from the initial FIU monitoring program. There are presently four active monitoring stations
within the Rookery Bay WBID (3278U) two of which are consistent with the locations of stations in the initial
FIU monitoring program. However, as of 2015, chlorophyll data were not reported at any of those stations. In the
Marco Island WBID (3278O) the City of Marco Island implemented an extensive bimonthly monitoring effort
within the canal system, which had previously not been sampled by FIU. This program included the one FIU
station within this WBID, but only until February 2015. Further south, there were seven monitoring stations over
the 2008-2018 period; however, only four of the sites remain active collecting samples quarterly. One of the
active stations was part of the initial FIU sampling effort.

Interpretation of Results and Discussion
When using the newer NNC criteria, it was determined that a number of Collier County’s coastal waterbodies
would be determined to be impaired. While the November 2018 results were draft, not final, and the ESA
determinations are not enforceable, there is a clear indication that Collier County may benefit from independently
evaluating the criteria and potential causative factors influencing impaired water quality. In response to findings
of water quality impairments, FDEP can prioritize (or not) the development of TMDLs. After the development of
a TMDL, Basin Management Action Plans (BMAPs) are developed, which seek to allocate nutrient load
reductions to various stakeholders, including local governments. BMAPs are intended to be “self-implementing”
through the NPDES program’s MS4 permitting process. In this way, potentially problematic determinations of
impairment can impact a local government’s budget, by compelling them to design, permit and construct
stormwater retrofit projects (as an example). While such programs and projects could very well be an appropriate
course of action, they could also be based on impairment determinations that are themselves based on
inappropriate conclusions reached without first considering the impacts of changes in station locations, changes in
the grouping of locations, or changes in water quality criteria over time.

In the case of waterbodies and ENRs which share the same spatial footprint, Collier County can have more
confidence in the impairment results. However, for systems with a wide range of salinities as is typical in an
estuary, a fixed criterion could result in erroneous impairment results. Clam Bay is the only WBID which has
adopted salinity-normalized criteria for nutrients. For those WBIDs in which salinity and nutrients are strongly
correlated, salinity-normalized criteria may provide the most effective tool for determining impairment status.
As regards to Naples Bay, it was declared impaired for chlorophyll-a, but not for TN or TP. This is a problematic
conclusion; as nutrient load reductions are often the only management action capable of addressing a finding of
excessive phytoplankton. In this case, a re-evaluation of the criteria is recommended to ensure that the
chlorophyll-a criterion is not overly protective or the nutrient criteria under-protective.
Caution is recommended when reviewing the impairment results when the spatial footprint of the ENRs and
WBID boundaries vary. In the case of Rookery Bay/Marco Island, there are multiple WBIDs within a single
ENR. In contrast, there are three ENRs within the Ten Thousand Island and Tidal Cocohatchee River waterbody.
As such, in many areas there appears to be a spatial disconnect between the areas in which the criteria were
developed and the areas where compliance is assessed. This is particularly relevant to Collier County, as the
monitoring efforts in the Rookery Bay/Marco Island ENR have changed substantially over the past 20 years. The
lack of consistency between sites used to develop the criteria and the current active sites can confound assessment
of trends over time as well as the water quality status.
Recommendations
Based on the findings presented here, a number of recommendations are listed below:
1. FDEP should review the appropriateness of combining Rookery Bay and Marco Island into a single ENR,
based on differences that were detectable in the original data set used to develop NNC criteria in their
2011 report
2. FDEP should examine the basis for impairment for water bodies exceeding NNC criteria predicated upon
a “hold the line” approach to resource management that show no evidence of degrading water quality
over the past decade, such as Rookery Bay / Marco Island
3. At the earliest opportunity, FDEP should review the appropriateness of basing NNC criteria on a data set
collected and analyzed by FIU compared to data sets collected and analyzed by different entities, to
ensure that differences in water quality are not the result of changes in sample locations, sampling
protocols or laboratory techniques
4. A proposed modification of existing sampling programs should be initiated, so that efforts would more
likely be focused on visiting the same locations as were used by FIU to develop the NNC criteria for each
ENR. In this way, differences in water quality over time would not be confounded by potential
differences due to changes in sampling locations within a given ENR.
