AGENDA APPROVAL Mr. Cravens motioned,Mr. Levy seconded to approve the agenda as amended.[Add item 13. Foundation's involvement in dredging; transpose items 4 and 5; and allow Ms. Johnson to address some issues when she arrived]. The agenda was approved as amended unanimously. AUDIENCE COMMENTS Discussion was briefly held with a member of the audience regarding the BCC's comments on the plan at their last meeting regarding the permit application and the Management Plan, and their interdependency, if any. Ms. O'Brien indicated that this had been done. Ms. Kathy Worley and Ms. Linda Roth expressed their desire to provide input for the Plan as well. Ms. Mary Johnson noted that the Foundation had expressed their support for the Management Plan that had previously been submitted, and expressed her concern with the subsequent, significant revisions to the Plan, noting that the Conservancy cannot support them. Ms. Marcia Cravens stated that the County Commission had expressed the fact that the updated Management Plan would be the guiding document and would be essential to include in permit applications. She also expressed her concerns with the Plan as it presently stands. Mr. Ken Dawson felt that the BCC Board was happy with the Plan that was presented, and was simply looking for some adjustments to it. Mr. Henry Bachman and Mr. Charles Bodo from the Foundation agreed with Ms. Johnson's comments about the changes that have been made, and asked that her opinions be honored. SUGGESTED EDITS FOR THE CLAM BAY NRPA MANAGEMENT PLAN Ms. O'Brien opened this discussion with one of the two issues the BCC had asked the Committee to concentrate on,that being the ecological considerations. She noted that Appendix 5 was authored by Dr. Dabees, and should have his name on it,printed as provided in his PDF file. The correct language regarding the ecological conditions was discussed, and it was suggested that a separate section be wordsmithed in the dredging chapter dealing with them to highlight their importance. Clam Bay Committee—Minutes October 28, 2014 Page 3 Mr. Tim Hall suggested that there are areas that need to be rewritten that would allow some slight impacts for the overall health of the system. Ms. Worley felt that the Plan should be about monitoring the entire system,rather than focusing on dredging. Mr. Hall felt that the ecological criteria should be determining the types of activities to be undertaken and their scope. Dr. Dabees added that the criteria that is now available allows action to be taken proactively as opposed to retroactively. After further discussion on these ideas and how to balance all of these important issues in the Plan,the Commission agreed that Mr. Hall and Ms. Worley would meet within the next week to reach an agreement on the specific wording to be used to cover both fresh water and ecological considerations, taking the suggestions of the Stakeholders into consideration as well. The Committee will meet the following week to go over the new wording. The objectives will remain the same as opposed to a few word changes, but the flow charts will be eliminated. UPDATE ON 10-YEAR DREDGING PERMIT APPLICATION All the data has been gathered for this, and the construction drawings are the final thing needed. Dr. Dabees will provide them to Mr. Dorrill in the near future, and they will be shared with the Foundation engineer prior to the scheduled November 6 meeting. It is anticipated that the Application will be completed for submission before the Thanksgiving holiday. APPROVAL OF MARCH 18,APRIL 8,APRIL 24, MAY 14 AND JUNE 11 MINUTES The minutes of March 18, April 8,April 24 and May 14 were approved at the September meeting after changes were made. A MOTION was made by Mr. Cravens to approve the above mentioned minutes as amended. After a brief discussion, it was agreed that the Committee would wait until the complete amended minutes were provided to them before they voted on their final approval. Mr. Cravens motioned,Mr. Levy seconded to approve the June 11 meeting minutes as amended.[Change Mr. Cravens to Dr. Trecker as distributing handouts;change$7,000 to $70,0001. The June 11 minutes were approved as amended unanimously. WATER QUALITY DATA IN STORET WATER QUALITY MONITORING UPDATE Mr. Hall advised those present that the DEP was satisfied with all the submitted information and is currently writing the amendments to the program, which should take another month to six weeks. Mr. Hall will input the present data into STORET. Clam Bay Committee—Minutes October 28, 2014 Page 4 NEW SAMPLING SITES STARTING IN JANUARY The new site sampling program is set to move forward as scheduled in January. The data backup for previously completed sampling will be provided to the DEP as requested. Two new reporting stations along the berm were briefly discussed and what the costs would be for the collections. Mr. Levy motioned,Mr. Cravens seconded to recommend to the full Board that two new sites for water collection be added along the berm at Stations 6 and 8, effective in January. The motion carried unanimously. ALTERNATIVE LAB FOR COPPER Mr. Hall will explore some alternative labs for copper testing and their costs and advise the Committee. CLAM BAY MONITORING SERVICES Handouts were provided to the Committee on the monitoring being done by Turrell,Hall and other Clam Bay related expenditures. This contract expires April. Ms. O'Brien asked for feedback on the Conflict of Interest Provision, and felt that a procedure should be in place to advise the Board of any other work Mr. Hall may be doing for any other entity as they go through the RFP process. Mr. Dorrill will check with the purchasing director to see if there is already a policy in place that addresses this issue, and will advise the Committee. CLAM BAY TIDAL RANGE DATA FROM MAY 2013 TO PRESENT This information continues to be collected on a regular basis, and Ms. O'Brien asked Mr. Dorrill if those numbers could be provided to them on a quarterly or monthly basis. Mr. Dorrill will see that this is done along with the water quality information that is being provided. Dr. Trecker motioned,Dr. Chicurel seconded to adjourn. The motion carried unanimously and meeting adjourned at 3:26 p.m. Susan O'Brien, Chairman 1/20/2015 9:57:19 AM CLAM BAY COMMITTEE THURSDAY,NOVEMBER 6,2014 The Clam Bay Committee of the Pelican Bay Services Division met Thursday,November 6 at 9:00 AM at the Pelican Bay Services Division office, located in the SunTrust Building, Suite 302, at 801 Laurel Oak Drive,Naples, Florida, 34108.

Clam Bay Committee-Minutes November 6, 2014 Page 2 AUDIENCE COMMENTS There were no comments received from the audience. REVIEW EDITS FOR CLAM BAY NRPA MANAGEMENT PLAN Ms. O'Brien thanked Ms. Kathy Worley, Ms. Mary Johnson and Mr. Tim Hall for all their efforts in making the Management Plan read as clearly and correctly as possible. The Committee went through the entire Plan,page-by-page, beginning with the Executive Summary,pointing out the previously submitted edits and the most recent edits. Some changes were made on these edits to clarify certain issues,to correct spellings and grammar,to insure compliance with the various requirements, to add references and subtract others where needed, and to substitute certain words for others when a particular meaning or intent could be made clearer. The Committee was mindful of redundancy as well as the need for consistency in certain instances when describing the different habitats throughout the Plan. The Committee discussed the wording"when necessary", "as necessary" and like phrases,which implied a decision by some entity when action is needed. It was agreed that wording would be added to the effect that the PBSD Board would be the entity to determine when necessary action is required as funds are available. The language concerning fresh water input into the Bay and the many considerations associated with it was discussed at length, and the Committee agreed on a few changes in the wording to clarify how and when any action would be taken. The language concerning a Pass closure due to a weather driven event was also discussed at length, and words to the effect that the inlet should be dredged"as soon as possible"were added. The dredging parameters were looked at again, and Ms. Worley,Mr. Hall and Dr. Dabees will confer via telephone on certain, more specific language related to this issue for insertion into the Plan. The Committee also inserted language indicating that after the Plan was approved by the PBSD and the BCC, it will become an integral part of future dredging and other relevant permit applications. The Committee went over the appendices as well, and some minor wording changes were made. Mr. Cravens motioned,Dr. Trecker seconded to approve the amended Plan. The motion I carried unanimously.

December 2014 Introduction The Clam Bay estuarine system is a 560-acre area of sandy beaches,shallow bays,seagrass beds and mangrove forests on the coast of Collier County in southwest Florida. The community of Pelican Bay abuts the northern and eastern edges of the system,while the Seagate and Naples Cay communities abut the southern portion of the system. The Clam Bay estuarine system is an important natural and recreational resource for local residents and visitors. Clam Bay was designated a Natural Resource Protection Area by the Board of County Commissioners of Collier County in 1994 (Collier County, 1994) and consists of approximately 360 acres of mangroves and some 130 acres of shallow,open water bays,as well as a 35 acre beachfront parcel(Clam Pass Beach Park).The system consists of three primary bays;Outer Clam Bay(southernmost),Inner Clam Bay(central),and Upper Clam Bay (northernmost), connected by a series of tidal creeks. 44-*..i'" ! le 2,f s • 0 . „nfti , _ t.,.....1.07*-. ,�,! �` � .q , ° + ti:♦ ',, t.mo t. a. � .

F ° i- A ..IL 0 ,(r_tft . r; ; { / N C A , The entire system receives runoff from adjacent upland and wetland areas. Upper Clam Bay is connected to Inner Clam Bay by a winding narrow creek.Inner Clam Bay is connected to Clam Pass through another narrow creek. Outer Clam Bay is connected to the Gulf of Mexico by a wider creek through Clam Pass. Some water also flows south to Doctor's pass through the culverts under Seagate Drive. Clam Pass is a small,marginally stable inlet that has migrated north and south along the shore over the years. Prior to dredging,average water depths were-1.0'to-2.5'with a width of 30-50' (Collier County, 1994).The Pass remains the primary source of tidal exchange for the Clam Bay system, but it is restricted by sediment deposits just inside the pass and in the long meandering tidal creeks surrounded by mangrove forests. The smaller embayments located primarily to the north of the pass are not subject to normal tidal exchange except during exceptionally high tides. Tidal range is restricted throughout the Clam Bay system (Turrell 1995; Tackney 1996). 1 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. December 2014 The system is bounded on the north by Vanderbilt Beach Road,to the south by Seagate Drive,to the east by the Pelican Bay development and to the west by the Gulf of Mexico. Pelican Bay is predominately a residential community of private single-family homes,as well as both high and low-rise condominium units. The community also includes a golf course,common areas with meeting rooms, tennis courts, beach park facilities, emergency services facilities, and commercial areas with shopping and hotels. The 2,104-acre Planned Unit Development (PUD) was approved in 1977 as a partnership between Collier Enterprises and Westinghouse Communities. It was one of the first developments in Florida required to save fragile coastal wetlands and associated ecosystems (Urban Land Institute, 1981). The development of Pelican Bay had a limited impact on the wetlands themselves(approximately 94 acres in total with about 78 of those acres located in the northwestern corner of the property)leaving the mangrove forest intact and preserved around the bays. In 1992 a small area of dead black mangroves was first observed in the northern part of the system. In 1995 a significant area (approximately 50 acres) of dead and dying mangroves was reported(Turrell, 1996). Following the die-off,restorative dredging was proposed to increase tidal flushing by opening up the pass and widening several tidal creeks within the system. The Florida Department of Environmental Protection(permit#0128463-001-JC)and the United States Army Corps of Engineers(permit#199602789(IP-CC)),authorized restoration activities in the Clam Bay system,in an effort to restore the mangrove communities that had died off. The restoration activities permitted by state and federal agency permits required a suite of monitoring activities to assess effects of the work efforts. Those permits expired in 2009 however, the Pelican Bay Services Division (PBSD), in an effort to remain informed of the condition of the system, and vigilant in their protection of it,pursued new permits in order to continue the maintenance of the flushing channels within the forest areas. Permits were granted by DEP(permit #11-0128463-005)and ACOE(permit#1996-02789)authorizing this activity. Maintenance of the main channel and Clam Pass have been undertaken through a separate permitting process. Like the previous permits,the new permits require annual monitoring of mangrove and other components within the system. This document presents a summary of the mangrove and seagrass monitoring which has taken place within this past year. It also summarizes tidal and water quality data collection that has occurred within this past year. Mangrove Monitoring Methodology The mangrove monitoring undertaken this year was a continuation of monitoring which was initiated under the old permits. The eleven existing Turrell,Hall monitoring plots and eight of the original Lewis mangrove plots were observed again this year. The previously established monitoring procedures were conducted. These included documenting the number and species of trees within the plot, as well as their approximate height. Each monitoring plot is a measured 10m x 10m square staked at each corner and marked in the center with a labeled PVC pipe. Monitoring activities included enumeration and mapping of living and dead trees with diameters at breast height(DBH)recorded for all living trees with a DBH greater than 2.5cm. Seedlings were identified by species and numbers were estimated by count or percent cover (where high numbers make individual enumeration difficult). In 2003, each measured tree was tagged and identified with a plot specific 2 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. December 2014 number to allow for easier tracking of individual trees as well as to allow easier comparisons over time. Any saplings that grow to sufficient size(>2.5cm DBH)between monitoring events are added to the tree counts and receive tags and numbers as well. Photographs are taken and any additional observations,including standing water,wildlife or signs of stress are noted. Time,tide, and prevailing weather conditions were also noted for each survey. Meandering transects were walked throughout the system to inspect stressed areas or to observe areas of concern related by residents of the community or identified through examination of aerial photographs.These surveys are conducted throughout the year as needed.Observations made during these pedestrian transects are noted in the general biological discussion of this report. A photographic timeline was completed again this past year. Concerns expressed by residents led to the establishment of photo points on the roofs of two condominium buildings adjacent to the mangrove area. Quarterly photos are taken from fixed positions on the roof of the Montenero and the Grovesnor condominium buildings. Over time, comparisons can be made of the photographs to determine if any additional die-off or gradual changes are occurring. In years past, scale rectified aerial photographs have been taken of the Clam Bay System by Aerial Cartographics of America. The aerials are produced at 200-scale in both color and infrared versions. Due to personnel changes and inconsistent communication,these photographs were not taken this year. Instead,scale rectified Collier County aerial photography from the property appraiser's office were used in conjunction with oblique photographs taken throughout the year to compare recovery and die-off areas for this annual report. Mangrove Monitoring Results A summary of the 19 monitoring plots have been included on the following pages. Plot discussions, comparative photographs, and tree compositions have been included on each individual plot page. 3 d n Number of live trees o o cn o 01 0 � 0 CD < - " '. .„ ‘ e...:-.- ,''''-A z-°\ - - 1,-.)

January 2014 • Grosvenor Roof November 2014 Grosvenor Roof December 2013 24 vow Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. January 2014 As a result of an observation of boring beetles attacking stressed trees in the early months of 2011 we began to capture photographs of Clam Bay from the rooftops of the Montenero and the Grosvenor. These panoramic pictures of the mangrove system are taken quarterly for comparison purposes. In addition to the annual mangrove monitoring these photos allow us to more frequently assess the overall health of the system and better identify and address any potential problem areas. Seagrass Monitoring Methodology Seagrasses are a valuable biotic indicator of environmental health and the PBSD has recognized the value in maintaining viable conditions for seagrass growth. The original permitted dredging design entailed impacts to seagrasses within the channel between Outer Clam Bay and Clam Pass. Monitoring over the life of the permit was designed to allow documentation of the regeneration or loss of seagrasses within the system and follow the effect of increased tidal flushing on seagrass aerial coverage and density within the potentially affected beds. These monitoring practices have continued in order to further document the overall health of the Clam Bay system. Monitoring methods include examination of aerial photographs and ground truthing by in-water and wading surveys. Accurate estimation of seagrass coverage is primarily hampered by visibility. The type of seagrass and limited visibility make estimation through examination of aerial photographs almost impossible. The most effective survey technique has been diving and wading transects and the most effective time has been at low tides when shallow water and substrate exposure make coverage estimation easier. Best effort was made to overcome the visibility obstacles in those areas that were deeper. Due to the ephemeral nature of the grasses being monitored,the survey methodology has been slightly modified from what was originally permitted in the 1998 permits. It was noted early on that the seagrasses shifted in location from year to year and that fixed quadrats in the same location year after year did not accurately depict seagrass coverage or presence within the Bay. More general observations of the presence of grasses along these transects have been used to locate the grass beds with the quadrat measurements used to quantify coverage within those areas where grasses are found. Grass beds in or adjacent to these transects are then mapped with a handheld GPS unit(Garmin Monterra) and transferred to an aerial exhibit. 25 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. January 2014 Seagrass Results Outer Clam Bay:Transect 1 Transect 1 was surveyed with snorkeling gear in water depths from 2 to 4 ft. Visibility was approximately 4 to 10 inches and again was easily reduced if sediments from the bottom were stirred up. Shoal grass (Halodule beaudettei) was found within quadrats 2, 4, 5, and 6 along this transect. The general area of grasses along this transect remained consistent with the last couple of years and has expanded slightly from the original pre-dredge monitoring. Densities of grasses remain consistent throughout with some minor losses but additional gains when compared to last year's monitoring period. In addition to the grasses, numerous southern hard clams (Mercenaria campechiensis), oysters (Crassostrea virginica) were also observed closer to the mangrove fringe line. Oyster clumps(approximately 6 inches by 6 inches),upside- down jellyfish (Cassiopeia xamachana), lightning whelks(Busycon contrarium),Florida fighting conchs (Strombus alatus),shell debris,and red,green and brown algae(Rhodophyta,Chlorophyta,and Phaeophyta) were also observed along Transect 1.

January 2014 Outer Clam Bay:Transect 2 Transect 2 was also surveyed via snorkeling gear. Water depths ranged from 1" to 3 ft. with visibility approximately 2 to 6 inches and again like Transect 1 this was easily reduced if sediments from the bottom were stirred up. No seagrasses were observed along half of this transect but shoal grass (Halodule beaudettei)was found on the other half. This is an improvement when compared to last year's monitoring period and reflects percentages that have been documented in past years. These grasses are ephemeral in nature and slight changes in water clarity and temperature have considerable effects on these grasses causing them to be present one year and not the next. There were also some southern hard clams (Mercenaria campechiensis), oysters (Crassostrea virginica), and lightning whelks (Busycon contrarium) that were observed along this transect.

January 2014 Outer Clam Bay: southwest sector, Transect 3 Transect 3 was surveyed with mask and snorkel gear. Water depths ranged from approximately 2 to 6 feet. Visibility varied between 12 to 24 inches. The patch of turtle grass(Thalassia testudinum)was observed along the western mangrove fringe line as it has in years past. This patch has been observed in the same location for the past several years and this year has slightly decreased in it overall density but still remains in good condition. The patch would still be considered small however hasn't grown in density and the blades remain approximately 4 to 12 inches long. In addition to the grass, both blue-green and red algae were present within the shallows.There was also a lot of Caulerpa present in and around this transect area. Other observations made along this transect included the Florida fighting conch(Strombus alatus),upside-down jellyfish(Cassiopeia xamachana)and a few scattered oysters(Crassostrea virginica)right along the fringe line of the mangroves.

Water depths ranged from 6 inches to 5 ft. with visibility of approximately 12 to 24 inches. The survey was conducted during an incoming tide. Again large patches of shoal grass(Halodule beaudettei)were observed along the western mangrove fringe line,and throughout most of this transect. Oysters were once again observed along the mangrove fringes on both east and west sides of the channel. Blue crabs(Callinectes sapidus),southern hard clams (Mercenaria campechiensis), and lightning whelks (Busycon contrarium) were observed scattered throughout this transect. Several fish species such as mangrove snapper(Lutjanus griseus),mullet (Mugil cephalus),and sheepshead(Archosargus probatocephalus)were also observed.

January 2014 Eastern side of waterway between pass and bay, Transect 5 Transect 5 was surveyed by both wading and snorkeling due to the same varying water depths as transect 4 has.Depths ranged from exposed substrate to 6 feet. In the original monitoring efforts,both shoal grass and paddle grass had been observed along this transect. As the tidal prism changed with the dredging activities, areas where grass had been present became subject to longer periods of exposure and some of the grasses died out. Shoal grass (Halodule beaudettei) was observed along this transect,however compared to last year's density and overall coverage there has been a slight decrease,however we feel this is just due to the ephemeral nature these seagrasses have. Shoal grass covers the majority of the mud flat along the eastern shoreline indicating the surrounding bay area could be fully recovered from the historic dredging impacts. Mud snails were observed throughout as well as Florida fighting conchs(Strombus alatus)were also seen scattered throughout the entire transects. Further continued monitoring will indicate if the return is permanent or not.

January 2014 Inner Pass, shoal area east of Clam Pass,Transect 6 Transect 6 is oriented north to south and covers a large portion of the shoal area just east of the Pass.This transect was surveyed by wading on account of the very shallow water depths which ranged from exposed substrate to approximately 4-6 inches. Visibility was not impaired. Large amounts of shoal grass(Halodule beaudettei)were observed scattered throughout the entire southern end of the flat,around quadrats 1,2,3,4, 5,and 6. Compared to last year the size and density of this large bed has remained about the same with the overall footprint changing slightly. The main change in coverage on this transect from past monitoring periods is that the grasses seem to have shifted more towards the southern half of this transect. Densities seem to have stayed about the same indicating a healthy thriving bed. Remaining portions of this transect consist of a sandy sediment with green mat algae, mud snails, and Florida fighting conchs(Strombus alatus).

Visibility was not impaired. Large amounts of shoal grass(Halodule beaudettei)were observed in the vicinity of the mangrove island,around quadrats 3 through 5.

The survey of this transect was conducted by both wading and snorkeling the survey line.Water depths ranged from exposed substrate to 4-5 feet with a visibility approximately 2 to 3 feet in the deeper portion of the channel. Shoal grass (Halodule beaudettei) was observed on the east side of the channel in the shallower water depths,in the same areas as previous monitoring periods. This seagrass bed has changed shape and density since the original monitoring efforts.The small patch of shoal grass observed two years ago on the west side of the channel was observed again this year,most likely due to sand build-up causing this area to just about dry up during low tides. Large groups of mud snails,a few Florida fighting conchs(Strombus alatus),and small patches of algae were also observed.

January 2014 Seagrass Summary Seagrass coverage overall totaled approximately 2.85 acres along the monitored transects within the Clam Bay system. What has been shown by the past thirteen years monitoring is that there was a decrease in the monitored seagrass beds immediately following the initial(1999)dredging activities.This decrease appears to have stabilized around 2004 or 2005 and has reversed in the past few years to where the grass beds are re- establishing previous areas and new areas appropriate for the grasses (in terms of water depths and light penetration) are being colonized. Future monitoring of the seagrasses will be conducted to see if this trend continues. Water Loggers Three continuous water level monitoring loggers were deployed in the system this year. These instruments help us to see how water levels within the mangrove forest react to tides and storm events. The graph below shows the water levels within the forest in comparison to the rainfall recorded within Pelican Bay during the same time period. 2013-2014 Rainfall Data 20 18 1 16 1 14 . 12 10 1. •1 1. 8 6 4 4.14 . 2.63._ 2,65 2. 2 ._. `1.04 —1.3 1. 1.= ,- '. 0 0.25 �`� e �+ met 7)013 2014 36 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

This is an indication that the water flow and flushing capacity of the system is still functional. Tide Gauges The tidal data and flushing analysis for the bays and main waterways within the system is presented under separate cover in a report from Humiston and Moore Engineers. Water Quality Testing Water quality sampling is conducted within the Clam Bay system on a monthly basis. Occasionally certain stations do not have enough water to sample,so those dates will not reference data for the various parameters. Three (3) stations: F. St. Lucia(berm), W-7 (north boardwalk),and PB-13 (north berm),were blocked in the fall of 2014 by construction. Water quality samples are collected by PBSD staff and transported to the Collier County Pollution Control laboratory for processing. All of the sampling data are not included in this report due to volume of pages making up this information.Sampling information is available for review and inspection at the PBSD offices. Field notes,chain of custody records,and laboratory reports are included in this data set.Of the parameters sampled and collected, dissolved oxygen(DO), Total Nitrogen(TN), Total Phosphorus (TP), copper (Cu), arsenic (As), cadmium (Cd), calcium (Ca), Lead (Pb), Magnesium (Mg), and Zinc (Zn) are 38 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. January 2014 discussed below. Discussion on these parameters is provided because they are the most indicative of nutrient loading and other potential water quality problems. The enclosed graphs show monthly measurements in the discussed parameters over the last year. Total Nitrogen (TN) Parameter Label Maximum Contaminant Maximum Contaminant (Name) Units Level(MCL) Level(MCL) Purpose of Sample Class II waters(saline) Class Ill waters(fresh) Measures the sum of Nitrate,Nitrite and Total Kjeldahl TN Nitrogen for a more complete picture of Nitrogen in a Total Nitrogen mg/L N/A N/A water system. High levels indicate the potential for algal bloom. Total Nitrogen is the sum of Nitrate, Nitrite and Total Kjeldahl Nitrogen measurements used for a more complete picture of the nitrogen stressors in an aquatic system. Nitrogen in a water or soil system can influence the system in both positive and negative ways. Nitrogen is important to both natural bacterial and plant growth. In larger quantities, nitrogen can also stimulate significant algal or plankton blooms, which can reduce the amount of oxygenated water and potentially cause blood diseases in fish and humans. Nitrate Nitrate (NO3) is highly soluble in water, relatively stable, and feeds the microscopic organisms that fish consume. It is the most oxidized and abundant form of inorganic nitrogen in water and the most concerning for health reasons. It can be dangerous in high concentrations, because it can cause blood oxygen deficiencies when it is converted internally to nitrite. While nitrate is much less toxic than ammonia or nitrite,high levels can inhibit growth,impair the immune system and cause stress in some aquatic species.In most cases of excess nitrate concentrations, the principle pathway of entering aquatic systems is through surface runoff from agricultural or landscaped areas which have received excess nitrate fertilizer. These levels of nitrate can also lead to algae blooms, and when nutrients become limiting (such as potassium, phosphate or nitrate) then eutrophication can occur. As well as leading to water anoxia(lack of oxygen),these blooms may cause other changes to ecosystem function, favoring some groups of organisms over others. Natural levels of nitrate in freshwater seldom exceed 0.1 mg/L, but waters influenced by human activity normally contain up to 5 mg/L as N with levels over 5 mg/L as N indicating pollution by animal or human waste or fertilizer runoff. All marine nitrate measurements were all below 0.1 mg/L and approximately 50%of the freshwater samples below 0.1 mg/L at the various berm stations. The highest reading was 0.71 mg/L at F. St. Lucia in July 2014. Nitrite Nitrite(NO2)is a less stable form of inorganic nitrogen,which quickly is converted to nitrate by bacteria. When oxygen levels in water get low,nitrate can be turned back to nitrite. Plants convert nitrate to nitrite and then to nitrogen gas ultimately in the Nitrogen cycle. Nitrite is a concern for drinking water because it has the ability to change the oxygen carrying hemoglobin to methemoglobin, which does not carry oxygen and can cause Blue Baby Syndrome in infants who lack the enzymes adults carry to convert it back to hemoglobin. EPA has established a regulatory limit of 1 mg/L of Nitrite in drinking water, but there is not a limit in water bodies. 39 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. January 2014 All Nitrite measurements taken were well below the regulatory limit for drinking water (1 mg/L), with the highest spikes reaching 0.018 mg/L for both marine and freshwater stations and the averages far below 0.018 mg/L. Total Kjeldahl Nitrogen Total Kjeldahl Nitrogen (TKN) is the measurement of organically bound nitrogen, ammonia (NO3) and ammonium(NO4+). TKN is typically the parameter used for measuring nitrogen levels in wastewater;however it is also used in soil and water analysis. The National Estuarine Eutrophication Survey classifies water samples containing greater than 1 mg/L TKN as high,samples containing between 0.1 and 1 mg/l as moderate and those containing less than 0.1 mg/1 as low in TKN. Of the measurements taken since October 2013,4%fell into what is considered a low TKN range,72%were in the moderate range and 24%were in the high range. Marine Samples-TN: Upper Clam Bay appears to consistently have the highest nitrogen accumulations of the marine sampling stations,which is to be expected since it is at the terminal end of the system and flushes the least. Levels in Upper Clam Bay are frequently twice that of other stations and remain higher throughout the year with or without heavy rainfall to frequently drive the levels. There was one(1)higher spike at W-1 (South Clam Bay) in March,which could possibly be influenced by particularly heavy February rains. 40 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

Total Phosphorus mg, cause an imbalance in cause an imbalance in High levels indicate potential for algal natural populations natural populations bloom. The total phosphorus test measures all the forms of phosphorus in a sample (orthophosphate, condensed phosphate,and organic phosphate).This is accomplished by first"digesting"(heating and acidifying)the sample to convert all the other forms to orthophosphate before measuring. An acceptable range for Total Phosphorus in water bodies is between 0.01 mg/L and 0.04 mg/L. There are no official standards for phosphorus, but the USEPA suggests a 0.1 mg/L maximum to prevent accelerated eutrophication.The National Estuarine Eutrophication Survey classifies samples with over 0.1 mg/L phosphorus as high,and samples with 0.01 to 0.1 mg/L as moderate in phosphorus content.Those samples under 0.01 mg/L are classified as low in phosphorus content. Natural concentrations of phosphorus in surface waters usually range from 0.005 to 0.020 mg/L,but phosphorus is normally found at concentrations less than 0.01 mg/L in high quality surface waters. 42 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc. January 2014 Total Phosphorus only occurred within the 0.01 to 0.04 mg/L range 14% of the time from October 2013 to November 2014, but within 0.01 to 0.1 mg/L 61% of the time. The highest reading was 0.98 mg/L at F. St. Lucia(November 2013). Upper Clam Bay had the highest total phosphorus levels of any measured marine locations consistently,with one exception during the October 2014 sampling event where W-1 depicted a spike significantly above its average. Upper Clam Bay also had an unusually high spike in April 2014, where no great changes can be detected in water temperature or salinity that might indicate an unexpected input.

Low levels indicate potential for algal Oxygen than 4.0 bloom. Dissolved oxygen (DO) is a measurement of the available oxygen in the water for aerobic organisms to use. Oxygen enters the water from the atmosphere and as a by-product of photosynthesis taking place under the water. Oxygen is removed from the water by respiration processes and decomposition of organic material. Typically, DO levels are directly related to a host of environmental factors. If there are too many primary producing organisms,plants,fish,or too much decomposition,then the oxygen demand increases greatly and thus the available oxygen decreases. Temperature is also one of the major influences of DO measurements. As the temperature increases, the photosynthetic activity taking place increases, using available oxygen. As a result, colder months typically have higher DO levels than summer months. Increased nutrient loading in water bodies can also lead to an increase in the oxygen demand, and thus a decrease in the overall health of the system. Both DEP and EPA recommend Dissolved Oxygen levels not fall below 5.0 mg/L for the health of aquatic 44 Clam Bay Annual Monitoring Turrell,Hall& Associates,Inc. January 2014 species in fresh water and for salt water not average less than 5.0 mg/L in a 24-hour period or fall below 4.0 mg/L. The levels of DO measured for this reporting event only provide a snapshot of the daily DO cycle. Dissolved Oxygen can fluctuate considerably throughout the day and thus a 24-hour diel study would be required to ascertain a true measurement of Dissolved Oxygen at each well station. Marine Samples-DO: W-6,nearest Clam Pass tends to have the highest Dissolved Oxygen levels of any sampling locations,followed closely by W-1,near the parking lot canoe launch,and North Seagate.

Copper (Cu) is naturally occuring in small quantities, but primarily enters waterbodies from wastewater discharge, herbicides and fungicides. Copper is measured in Pelican Bay primarily due to the use of Copper Sulfates in lakes to eradicate or control alge and aquatic weeds. Past stormwater lake testing has shown high to extremely high copper levels are present frequently,so downstream sampling in the surface water management system and in the estuary are important in gauging the future health of the system. Oddly,W-6,which is nearest the pass and has the best seawater exchange of any station,has the highest spike of marine-measured copper at a hundred times the limit. Upper Clam Bay measured the second highest spike. Remaining samples were closer to the limit of 3.7 µg/L, but were still frequently found at twice that level. 47 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

Arsenic(As)occurs naturally in our environment,but can be released further from man-made disturbances. It is also found in paints, dyes, soaps, fertilizers, drugs and metals. Higher arsenic levels tend to be found in groundwater as opposed to surface water. Arsenic can cause a wide array of severe health issues in humans and animals so a water quality standard was implemented for both Class II saline and Class III non-saline surface waters of < 50 .tg/L. A 10 µg/L arsenic limit was also established for drinking water. As can be seen below the vast majority of arsenic readings were below the lowest detectable limit the lab can analyze(4.0µg/L). There were a few detectable spikes at Wells 1,6 and 7 and North Seagate,but they were still more than five (5) times lower than the limit. The highest reading (7.78 .ig/L) was taken at W-6 (middle boardwalk) in June 2014. None of the berm readings were above the lab detectable limit so that table was not included for reference since there would be no graph. 51 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

Cadminum(Cd)is a minor natural constituent of surface and groundwater,but typically enters the water colum from a point source or non-point source discharge;typically sludges and fertilizers. Cadmium can typically be found varying from 0.005 to 0.11 gg/L naturally in seawater, with higher levels in certain coastal areas, according to the World Health Organization(WHO). Cadmium(Cd)has a limit in both fresh and saline environments of 9.3 gg/L.,while the drinking water limit of Cadmium is 5 gg/L. The Collier County Lab cannot detect Cadmium below 2.0 gg/L and none of the samples for any station, marine or freshwater, were within a measurable range. 52 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

Calcium (Ca) is found typically in levels of 400 mg/L in seawater, with a wider range of 1 to 100 mg/L in freshwater. Primarily Calcium is introduced as the base rock dissolves,but it is also released from fertilizers. Calcium is an important determinant of water hardness and it functions as a pH stablizer. It is also important for bone and teeth growth. Water hardness influences aquatic organisms concerning metal toxicity.In softer water membrane permeability in the gills is increased. Calcium also competes with other ions for binding spots in the gills. Consequently, hard water better protects fishes from direct metal uptake. In saline samples,Calcium was typically around the expected quantity of 400 mg/L except in a few samples. It was also slightly below typical for freshwater in all but three(3)samples at PB-13 (north berm),which is also the station which shows evidence of freshwater and saltwater mixing. 53 Clam Bay Annual Monitoring Turrell,Hall&Associates,Inc.

Magnesium(Mn)naturally occrs in the soil and rock substrate and can be released into the water column from breakdown of those;however it also can be introduced through fertilizer application. Mangesium,plays a role in water hardness and is required for plant and human tissue function. Magnesium in typical marine waters is 1,300 mg/L, while freshwater streams and rivers typically have approximately 3.99 mg/L of Mg present. Marine samples in Pelican Bay were on the lower side of typical marine Mg values, while freshwater samples were on the high side. PB-13 (north berm) samples were extremely high for freshwater,but low for saline environments. PB-13 has shown other relationships in terms of water quality to a more saline system, so some level of mixing must be occuring at this station. 55 Clam Bay Annual Monitoring Turrell,Hall& Associates,Inc.

For verifying natural background the movement of stormwater or intrusion of saltwater in the system. Since open marine water body salinity runs in the lower to mid-30s(parts per thousand),examination of salinity levels throughout the Clam Bay system will verify whether freshwater inputs are able to flush quickly enough to prevent mangrove decline. It also serves to verify that saltwater is not intruding into the interior lakes and water management systems to any concerning degree. Overall salinity levels dropped by nearly half during the rainy season,with the exception of Upper Clam Bay which remains a little lower and plumets during the rainy season. A notable observation is the salinity levels at PB-13 (north berm). All other berm and condominium sampling station had very low salinity levels typical of freshwater systems. Based on the data, PB-13 must receive some level of flushing.

January 2014 Summary Since the issuance of the permits(DEP permit#11-0128463-005 and ACOE permit#1996-02789)authorizing the maintenance activities in 2009 the restoration successes realized within the mangrove forest of Clam Bay have been continued. The majority of the monitoring plots show continued increases in mangrove numbers and sizes though many of them are starting to level off. Two plots(Plots 4 and 9)have been consistently hampered by exotic vegetation and dense ground cover growth. Ongoing exotic eradication activities will allow for the eventual re-establishment of natural native vegetative community within these areas. Another plot(#11)has started to transition from a white mangrove dominated area to a more open black and red mangrove area. As a result, many of the sapling white mangroves have died off in the preceding few years. This is a natural progression and we expect to see everything level off in the next couple of years. Quarterly panoramic photograph now being incorporated into our monitoring of the Clam Bay System are shot from the rooftops of the Montenero and the Grosvenor high-rises. The elevated vantage point allows for a more frequent, broad assessment of the mangrove area and allows us to better assess resident's concerns regarding mangrove health when they are raised. The photographic comparisons from this year to years past show little observable changes though the white mangroves that had been killed by the boring beetles a few years ago are still visible. Water quality monitoring conducted this year will be the final effort utilizing the past parameters and monitoring locations. Based on the updated management plan that has been under review,an increased number of locations within the bays will be sampled and a slightly modified suite of parameters will be sampled. Please see the Clam Bay NRPA Management Plan for the new locations and additional details on the future monitoring efforts. Over time the hope is to document improvements within the Clam Bay waters associated with water quality improvement activities being undertaken within the development. Annual inspection of the flushing cuts throughout the system will be continued. These cuts are vital to the continued health of the system and must be maintained so that the water flows and flushing capabilities within the mangrove forest is protected. All canoe trail markers were replaced this year due to extensive damage of the previous marker's piles by marine borers. The new markers were installed with different pilings and those pilings were wrapped with PVC in an effort to extend their lifespan by offering additional protection from the marine borers. Periodic inspections will be undertaken to make sure the poles remain viable. Catastrophic failure of several of the tidal data loggers this year has led to an effort to replace the outdated equipment with updated,real time data sensors. These new loggers are expected to be in place during the first quarter of 2015 and will provide the data needed to monitor the Pass and interior Bay and Creek connections to insure tidal flushing remains sufficient to maintain the health of the system. This year's monitoring has shown that the system continues to recover and both mangrove and seagrass recruitment have been documented though continued vigilance is called for to maintain a viable functioning ecosystem at Clam Bay. The upcoming year is expected to be a busy one due to implementation of the new Clam Bay NRPA Management Plan, installation of new tidal data loggers, implementation of a new water _ quality monitoring program,and application for new long term permits for maintenance dredging of Clam Pass. - 63 a it IP -' zL ar' w..,.., S E ,i1. 1 'W^ 0 t.,. �� "-- rS ' 9 .

There are several current County positions that may be similar to what PBSD may determine it needs. These positions provide information on both how the County outlines job expectations and compensation levels. These positions include Environmental Specialist,Principal,a grade 21 position, and Environmental Specialist,Senior a grade 18 position. Attached is information about 2015 salary ranges for various grades in the County. Ms. Lyberg said using+35% is a good way to calculate the estimated cost of the County's benefit package. Also attached is the County's job description for the Environmental Specialist, Principal that could possibly be used to develop a job description for a PBSD-based scientist position. Mr. Lorenz said his department is in the process of hiring an environmental specialist, and he seemed pleased with the quality of the applicants and quantity (about 20) of the applications. He stated that the County's pay scale is slightly higher than the State of Florida's so some of the applicants were current State employees with very good and relevant experience. Ms. Lyberg said that the County is currently updating its comparative salary study so that County salaries remain competitive in the region. Mr. Lorenz also said that the PBSD may be able to use County employees who work is his department to collect monthly water samples. At some point the cost of this option could be compared to the costs of having PBSD-based employees and CH2MHil1-provided workers doing this work. Should the PBSD Board ultimately decide to proceed with hiring a scientist, Ms. Lyberg said the process would begin by requesting approval for a position from the BCC.

Lisa Original Message From:david trecker = = c n Sent:Wednesday,January 14,2015 1:48 PM To:ResnickLisa Subject:Water Quality Guru Lisa-Please forward the following as a one-way message to the directors and Neil.Thanks,Dave The board has expressed interest in locating an expert to oversee/coordinate water-quality programs in the upland lakes and Clam Bay.The rationale is that the programs are complex,interrelated and would benefit at this time from management by a true expert.Among the issues are copper monitoring and,perhaps,remediation;water quality in Clam Bay vs FDEP guidelines;non-copper-based algae/duckweed control in the lakes.I have been involved in these programs for some time and,along with others,have interacted with a number of possible candidates for such a job.I recently spoke by phone with three of them. Dr.David Tomasko(ESA/Water)has consulted extensively with Collier County and the PB Foundation and was instrumental in drafting FDEP nutrient standards for Clam Bay.He is will known and respected and has broad knowledge about Clam Bay and its water-quality status.He is very well plugged into the FDEP.He would be interested in a management/oversight role. Jim Bays(CH2M Hill)has an M.S.in Environmental Engineering and has consulted with us on a number of occasions.He is an expert on both freshwater lakes and brackish-water estuaries and knows our issues well. He too would be interested in such a consulting position. Steve Gong(retired,formerly with CH2M Hill)has an M.S. in Marine Ecology.He previously coordinated our lake sampling,analysis and reporting and,as such,knows our situation well. He has had extensive experience dealing with the FDEP_He indicated he might be interested in a management/oversight role. Dr.Serge Thomas(FGCU)is the fourth candidate. He is a true expert on water-quality problems in lakes and estuaries.I have not spoken with him because of his constraints as an academic. I have some idea of costs and can review these with the WM and CB Committees. The take-home message is that there are people out there who could coordinate and manage our water-quality programs. Dave Under Florida Law,e-mail addresses are public records. If you do not want your e-mail address released in response to a public records request,do not send electronic mail to this entity. Instead,contact this office by telephone or in writing.
