Agenda 2/14/2023 Item #11D (Approve Change Order for Tigertail Lagoon/Sand Dollar Island Ecosystem Project)02/ 14/2023 EXECUTIVE SUMMARY Recommendation to approve a one-time expenditure of Tourist Development Tax Fund 195 funding in the amount of $921,400 for 85,000 cubic yards of dredged sand itemized in Change Orders #1 and Change Order #2 to the City of Marco Island's contract with Ahtna Marine & Construction for the 2022 Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project, authorize the Chair to execute a Tourist Development Tax Funding Agreement, authorize the necessary budget amendment and make a finding that this expenditure promotes tourism. OBJECTIVE: To approve the City of Marco Island's request for funding. CONSIDERATIONS: The City of Marco Island is requesting $921,400 in Tourist Development Tax funds from Collier County for the Tigertail Lagoon/Sand Dollar Island Project that is currently under construction. The purpose of the project is to restore impacts from Hurricane Irma, and improve coastal resiliency, water quality, stability and improvement of Tigertail Lagoon and Sand Dollar Island. This is a FDEP permitted and awarded City project that is currently under construction and due to the impacts of Hurricane Ian additional funds are required to complete the restoration project as designed. The following information was provided by the City of Marco Island and prepared by engineer Mohamed Dabees, P.E.. The project was permitted by the Florida Department of Environmental Protection and the US Army Corps of Engineers in February and July of 2022, respectively. The project construction contract was funded by the City's Hideaway Beach Tax District and awarded to Ahtna Marine & Construction Company in September 2022 for $3.3M. The Tigertail Lagoon/Sand Dollar Island Ecosystem Restoration project is a City of Marco Island project designed to restore and protect valuable ecosystem, recreational assets and tourist attractions. The project in its entirety is located on public beach and wetland areas designated as Critical Wildlife Area by the State of Florida and can only be accessed by land through Collier County Tigertail Beach Park at the south part of the system. The project is in the public interest providing environmental, social, and economic benefits and storm protection. The Tigertail Lagoon and Sand Dollar Island ecosystem is a protected natural preserve and a critical wildlife area that provides valuable habitat for a variety of birds, sea turtles, manatees, and seagrasses. Tigertail Lagoon and Sand Dollar Island are also valuable Collier County recreational resources for residents and tourists for birding, fishing, kayaking, paddle boarding, kitesurfing, walking, shelling and, on the northern half, boating. The ecosystem is accessed by the public via Collier County's Tigertail Beach Park at the southern end of the lagoon and via boat at the northern end of the lagoon. Tigertail Beach is one of 510 points on the Great Florida Birding and Wildlife Trail and is considered one of the best all-around birding spots in southwest Florida. The County Park is one of only three public beach access points on Marco Island and receives over 200,000 visitors annually. It has a large public parking area, playground, food concession, and watercraft rentals. A shuttle bus runs from some hotels to the park. An increasing number of private, rental, and commercial tourist boats access the lagoon from its northern entrance. The Tigertail Lagoon and Sand Dollar Island system was impacted by Hurricane Irma in 2017 and was evolving toward closure when it was further impacted by Hurricane Ian in September 2022. Hurricane Ian impacted the project area by reducing the sand available in the permitted dredge template and increasing the sand required to build the protective berm on Sand Dollar Island. The City of Marco Island initially funded an additional 25,000 cubic yards of dredging from a combination of contingency allowance and Change Order No. 1. Funding for an additional 60,000 cubic yards was requested from the use of Tourist Development Tax fund 195. The Tourist Development Council recommended and approved Packet Pg. 520 02/ 14/2023 the funding of the additional 60,000 cubic yards as well as the reimbursement to the City for the initial 25,000 cubic yards of dredging. The total amount for the expenditure associated with this item is $921,400 for the dredging and placement of 85,000 cubic yards on Sand Dollar Island at $10.84/cu yd. This sand will address Hurricane Ian's impact on the project area and allow completion of the beach berm on Sand Dollar Island as designed. The beach berm will provide storm protection for the newly reopened lagoon flow channel connecting the southern lagoon by the County's Tigertail Beach Park with the northern lagoon/Gulf entrance that enhances tidal flow and water quality and lagoon recreation for the public. It also protects the FWC Critical Wildlife Area that is one of the main attractions of the County Park. In addition, this beach berm restores a section of Sand Dollar Island shoreline within the County Park providing dry recreational beach for the public and maintaining public access to the 2-mile-long Sand Dollar Island. A Tourist Development Tax Funding Agreement between the County and the City of Marco Island will be necessary to allow the County to reimburse the City of Marco for eligible project expenditures. GROWTH MANAGEMENT IMPACT: There is no impact to the Growth Management Plan related to this action. ADVISORY COMMITTEE RECOMMENDATIONS: Coastal Advisory Committee (CAC) recommended approval of this expenditure 8-0 on January 12, 2023; however, the CAC did not agree to limit the funding to a one- time request. The Tourist Development Council (TDC) recommended approval of this expenditure 7-0 on January 23, 2023, and also recommended approval of the reimbursement to the Hideaway Taxing District of the additional 25,000 yards in relation to Change Order #1 for a total of 85,000 cubic yards of sand. LEGAL CONSIDERATIONS: Pursuant to Section 125.0104, Fla. Stat., Lagoon improvement is an authorized use of tourist development tax revenue with a recommended finding that the item promotes tourism. Section 125.0104(5)(a)5, provides in relevant part: To finance beach park facilities, or beach, channel, estuary, or lagoon improvement, maintenance, renourishment, restoration, and erosion control, including construction of beach groins and shoreline protection, enhancement, cleanup, or restoration of inland lakes and rivers to which there is public access as those uses relate to the physical preservation of the beach, shoreline, channel, estuary, lagoon, or inland lake or river. This item is approved as to form and legality and requires majority vote for approval. - CMG STAFF RECOMMENDATION: Collier County's Coastal Zone staff has reviewed and supports the request as it pertains to the Tigertail Lagoon as a one-time contribution to the Project in the total amount requested by the City of Marco Island of $921,400 (85,000 cubic yards of sand at $10.84 per cubic yard) FISCAL IMPACT: A budget amendment is required in the amount of $921,400 to reallocate funding within the TDC Beach Renourishment Fund (195) from reserves to Tigertail Lagoon Project (90007) for a one-time remittance to the City of Marco Island. The source of funding is the Tourist Development Tax. RECOMMENDATION: To approve a one-time expenditure of Tourist Development Tax Fund 195 funding in the amount of $921,400 for 85,000 cubic yards of dredged sand itemized in Change Orders #1 and Change Order #2 to the City of Marco Island's contract with Ahtna Marine & Construction for the 2022 Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project, authorize the Chair to execute a Tourist Development Tax Funding Agreement, authorize the necessary budget amendment and make a finding that this expenditure promotes tourism.

City of ` Marco Island January 3, 2022 Andrew Miller, P.E. Coastal Zone Manager Collier County 2685 South Horseshoe Drive Unit 103 Naples, FL 34104 Dear Mr. Miller, As a follow up to the City of Marco Island's presentation at the December 8, 2022 Coastal Advisory Committee meeting, this letter and attachment provide the City's request for supplemental funding for the Tigertail Lagoon/Sand Dollar Island Ecosystem Restoration Project at the January 12, 2023 CAC meeting. Please include this letter and the attached documentation with the CAC agenda item. Although the City was able to fully fund the $3,306,187.50 project at the time, the impacts from Hurricane Ian resulted in additional costs for which the City is requesting supplemental funding assistance from the County in the amount of $921,400. The supplemental funding will be used to fund a change order for 85,000 cubic yards of sand from the permitted offshore borrow area at a cost of $10.84/cu yd and to place this sand on Sand Dollar Island. This sand will address Hurricane Ian's impact on the project area and allow completion of the berm on Sand Dollar Island as designed. The berm will provide storm protection for the newly reopened waterway connecting the southern lagoon by the County Park with the northern lagoon/gulf entrance that enhances tidal flow and water quality and lagoon recreation for the public. It also protects the Critical Wildlife Area that is one of the main attractions of the County Park. Finally, this berm also restores a section of Sand Dollar Island shoreline within the County Park with dry recreational beach for the public and maintains public access to Sand Dollar Island. This request for supplemental funding enables the City to complete this project. After Hurricane Ian, it would be extremely unfortunate not to do this when the resources could be made available, a contractor is on site, and a very favorable rate has been extended. Failure to act now will require future remedial action much more quickly than projected and at a far higher future cost. The only other alternative is to let Tigertail Lagoon at the County Park become a stagnant pond which no one should be advocating. We hope that you and the CAC will provide a positive recommendation for the requested funding. Sincerely, 10� 4M�� GJustin Martin, P.E.

Coastal Zone Manager Collier County 2685 South Horseshoe Drive Unit 103 Naples, FL 34104 Dear Mr. Miller, As a follow up to the City of Marco Island's presentation at the December 8, 2022 Coastal Advisory Committee meeting, this letter and attachment provide the City's request for supplemental funding for the Tigertail Lagoon/Sand Dollar Island Ecosystem Restoration Project at the January 12, 2023 CAC meeting. Please include this letter and the attached documentation with the CAC agenda item. Although the City was able to fully fund the $3,306,187.50 project at the time, the impacts from Hurricane Ian resulted in additional costs for which the City is requesting supplemental funding assistance from the County in the amount of $921,400. The supplemental funding will be used to fund a change order for 85,000 cubic yards of sand from the permitted offshore borrow area at a cost of $10.84/cu yd and to place this sand on Sand Dollar Island. This sand will address Hurricane Ian's impact on the project area and allow completion of the berm on Sand Dollar Island as designed. The berm will provide storm protection for the newly reopened waterway connecting the southern lagoon by the County Park with the northern lagoon/gulf entrance that enhances tidal flow and water quality and lagoon recreation for the public. It also protects the Critical Wildlife Area that is one of the main attractions of the County Park. Finally, this berm also restores a section of Sand Dollar Island shoreline within the County Park with dry recreational beach for the public and maintains public access to Sand Dollar Island. This request for supplemental funding enables the City to complete this project. After Hurricane Ian, it would be extremely unfortunate not to do this when the resources could be made available, a contractor is on site, and a very favorable rate has been extended. Failure to act now will require future remedial action much more quickly than projected and at a far higher future cost. The only other alternative is to let Tigertail Lagoon at the County Park become a stagnant pond which no one should be advocating. We hope that you and the CAC will provide a positive recommendation for the requested funding. Sincerely, CJustin Martin, P.E.

This report is provided as a follow up to the informational meeting and materials presented at the December 2022 Collier County Coastal Advisory Committee meeting. The project which aims to restore impacts from Hurricane Irma, and improve coastal resiliency, water quality and stability of Tigertail Lagoon and Sand Dollar Island is in public interest while providing environmental and recreational benefits. This is a permitted and awarded city project that is currently under construction, and due to the impacts of Hurricane Ian supplemental funds are required to complete the restoration project. The project TDC funding request is for assistance relating to increased project costs due to impacts from Hurricane Ian. The information herein is provided for additional clarity on the benefits of the project as support to local tourism and continued public use of the county park and areas enhanced by this project. II. Project Overview The Tigertail Lagoon/Sand Dollar Island Restoration on Marco Island is designed to maintain and enhance an existing coastal barrier system consisting of a 2-mile-long sand spit and tidal lagoon ecosystem along the northwest shoreline of Marco Island. The Tigertail Lagoon and Sand Dollar Island ecosystem is a protected natural preserve and a critical wildlife area that provides valuable habitat for a variety of birds, sea turtles, manatees, and seagrasses. The Tigertail Lagoon and Sand Dollar Island system was impacted by Hurricane Irma in 2017 and was evolving toward closure when it was further impacted by Hurricane Ian in late September this year. The project is part of a nature -based adaptive management plan to restore and stabilize the sandspit and tidal lagoon through cyclic use of sediment within the system. It is funded by the City of Marco Island through the Hideaway Beach Tax District. The project aims to restore and enhance the barrier sandspit degraded by a sequence of storms since Hurricane Irma and re-establish the continuous lagoon flow channel thereby enhancing tidal exchange and water quality. Total wetland area will be increased by relocating a portion of the sand spit seaward of its present location to where it was located in approximately 2017. Figure 1 illustrates the project elements and main features including the protective beach berm, sand trap and flow channel. • Protective beach berm: The constructed beach berm will provide enhanced resiliency to high frequency weather events protecting the lagoon, the critical wildlife area and maintain public access to the pristine beach and wildlife of this unique environmental and recreational tourist attraction. • Sand Trap: the sand trap at the north end of Sand Dollar Island is the main source of sediment that will also maintain the northern lagoon entrance open to the gulf, while providing beneficial re -use for excess sediment that continues to accumulate at the end of the spit. • Flow Channel: the project includes establishing a flow channel that connects the south part of the lagoon at Tigertail Beach Park to the north part of the lagoon to maintain tidal flow and improve water quality and public safety. 2 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island Offshore Borrow Area Navigation Channel A %r+MMa4K 4 Collier County Tigertail Beach Park %-4 r. Figure 1. Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration project features 3 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island • Regional sand management: the project also provides improved and sustainable regional sand management for adjacent inlets at the north part of Marco Island. The sand trap is designed to reduce shoaling rates at the entrance to lagoon and may also reduce shoaling rates at the entrance to Collier Creek. The Sand Dollar Island beach berm will also provide a sustainable disposal area for maintenance dredging of the entrance Collier Creek in lieu of the offshore borrow area which has limited capacity and intersects with the Capri Pass Navigation Channel (Figure 1). III. Public interest and recreational benefits Tigertail Lagoon and Sand Dollar Island are valuable Marco Island and Collier County recreational resources for residents and tourists for birding, fishing, kayaking, paddle boarding, kitesurfing, and boating. A. Access The project in its entirety is located on public beach and wetland areas designated as Critical Wildlife Area by the State of Florida and can only be accessed by land through the Collier County Tigertail Beach Park at the south part of the system. Tigertail Beach Park is one of 510 points on the Great Florida Birding and Wildlife Trail and is considered one of the best all-around birding spots in southwest Florida. The County Park is one of only three public beach access points on Marco Island and receives over 200,000 visitors annually. It has a large public parking area, playground, food concession, and watercraft rentals. A shuttle bus runs from some hotels to the park. In addition, an increasing number of private, rental, and commercial tourist boats access the lagoon from its northern entrance. Figure 2. Tigertail Beach Park access to the Critical Wildlife Area 4 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island B. Tigertail Beach Park: Project development and benefits The Tigertail Lagoon portion within the County Park constitutes approximately 30 % of the total lagoon area. Figure 2 shows a map of Tigertail Lagoon /Sand Dollar Island Critical Wildlife Area and the Park as part of this system. Figure 3 shows the features and attractions of the County Park as listed on the park entrance sign including shore bird watching, lagoon and beach recreational activities. These recreational features are threatened due to the system degradation since Hurricane Irma in 2017 and near collapse following Hurricane Ian in 2022. The system degradation and concerns of the park visitors were echoed by the actions of the Friends of Tigertail (FOT), a 501-C3 entity with a mission to preserve and protect the Tigertail Beach area of Collier County. FOT reached out to Collier County, City of Marco and others raising concerns about the park conditions and requesting attention and assistance to restore the lagoon post Hurricane Irma. Several public meetings with all stakeholders including Collier County were led by FOT and held in 2019 and 2020. The City of Marco Island through funding from Hideaway Beach Tax district initiated the project permitting later in 2020. A pre -application meeting with permitting agencies and all stakeholders was held in January 2021 including representatives from various departments and management of Collier County. The City of Marco Island filed permit applications in April 2021. The project was permitted by the Florida Department of Environmental Protection and the US Army Corps of Engineers in February and July of 2022, respectively. A detailed timeline of the project is enclosed, Appendix A. Figure 3 also illustrates the park access and pathways to the gulf shoreline of Sand Dollar Island fronting the park area. The figure also shows the severe erosion along the park gulf shoreline which was further impacted by Hurricane Ian in September of 2022. The Tigertail Beach Park will benefit from the lagoon's significantly improved tidal flow and the stabilization of wetland and beach areas that are susceptible to over wash and onshore collapse. The top panel of Figure 4 shows the post Hurricane Ian conditions showing the severe erosion of the gulf shore of the northern part of the park, the shoaling and collapse of the middle part of sand dollar island, and the loss of flow connectivity to the norther part of the lagoon. All threatening to diminish the value of the main features of the park. The bottom panel of Figure 4 shows the project benefits including reestablishing tidal flow to the lagoon through the flow channel and establishing a protective beach berm that not only will maintain beach access to park visitors but also protect the flow channel from frequent shoaling and closure. The project design includes approximately 100,000 CY over approximately % mile at the Gulf shoreline of the park. The project benefits also include environmental and water quality monitoring including installation of a tidal flow and water quality monitoring station in the park lagoon. 5 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island Tigertail beach Park sign illustrating the Park features and tourist attractions Public access pathways to gulf beach where the shoreline has retreated significantly and undermined dune Park shoreline where the eroding beach is further impacted by Hurricane Ian Figure 3.

State determination on project's public interest and recreational benefits As part of the State Department of Environmental Protection (DEP) review and processing of state JCP permit 0401778-001-JC, the technical environmental and coastal engineering staff and the program administrative staff have determined that the project is in the public interest and maintain access to environmental and recreational benefits to the public. The following points provide summary findings from documentation and statements from Intent to Issue by DEP. • The overwash and shoaling along the middle section of Sand Dollar Island and Tigertail Lagoon is causing loss of lagoon habitat. • The proposed project may reduce potential for adverse impacts to public health, safety and welfare should the lagoon become stagnant. • The proposed project will allow for continued use of the area by the public for wildlife observation and other recreation uses. • The project will have a net positive benefit to the coastal system. • The project is in the public interest providing environmental, social and economic benefits and provide more storm protection. • The project is expected to maintain this area as an environmental and recreational resource to the public. • The project meets the Department criteria for public interest determination. Figure 5 provides excerpts from DEP Intent to issue document establishing those findings. The complete document is enclosed in Attachment B 8 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island Florida Department of Environmental Protection December 21, 2021 Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Notice of Intent to Issue Joint Coastal Permit and Authorization to use Sovereign Submerged Lands Background (bottom of pg 3): Storm events leading to overwash of the central segment of Sand Dollar Island and shoaling of the mid -section of Tigertail Lagoon is causing loss of lagoon habitat. (Top paragraph pg 4) The proposed project will result in restoring and enhancing aquatic and upland habitats within the coastal ecosystem of the Tigertail Lagoon / Sand Dollar Island (TLSDI) system that have deteriorated over time. (Public Health, Safety or Welfare middle of pg 8) The proposed ecosystem restoration project may reduce the potential for adverse impacts to public health, safety or welfare to occur, should the lagoon become stagnant. (Recreational benefits bottom of page 8) The restoration and maintenance of the TLSDI will allow continued use by the public for observation of wildlife, sunbathing, swimming, surfing, recreational fishing and related activities. Florida Administrative Code (Rule) requirement (pg 11) Rule 62B-41.005(2), F.A.C. coastal construction authorized by the Department shall have a net positive benefit to the coastal system. Sovereign Lands Requirements (pg 12) Pursuant to Rule 18-21.003(53), F.A.C., The proposed project would be in the public interest because the activity provides demonstrable environmental, social, and economic benefits, by maintaining a navigable waterway, and providing more storm protection, without causing any significant environmental harm. (and top of pg 13) The proposed project is expected to maintain this environmental and recreational resource so that the public may continue to enjoy traditional uses of the TLSDI system, including but not limited to, boating, fishing, and swimming. Removing the overwashed sand from the lagoon will restore natural habitat and return the biological and recreational value of the area. Public Interest (top of pg 15) After weighing the effects of the project for each of the public interest criteria specified in Section 373.414(1), F.S., and the Environmental Resource Permit Application Handbook, Volume 1, 10.2.3., and based on reasonable assurance provided by the Applicant, the Department has determined that the proposed activity is clearly in the public interest.

Hurricane Ian Impact The City of Marco Island awarded the project to Ahtna Marine & Construction Company in September 2022 for a total of $3.3 million prior to Hurricane Ian. Hurricane Ian impacted Collier County and the project area on September 28, 2022, resulting in additional onshore migration and overwash of the sand spit protecting the lagoon. Preconstruction surveys in October 2022 documented conditions post Hurricane Ian and were used to produce updated construction plans. Hurricane Ian caused a reduction in available sediment and an increase in required sediment to construct the beach berm. Sediment from an existing offshore borrow area authorized within the project permit as a contingency sand source will need to be utilized to supplement the project construction and achieve the designed beach berm. V. Project Construction Costs and County Funding Request The City of Marco Island awarded the project to the contractor Ahtna Marine & Construction Company in September 2022 for a total of $3.3 million. Ahtna Marine & Construction Company prepared a proposal to the city for change order consideration to obtain the additional 85,000 cubic yards (CY) from the offshore borrow area which is authorized by the project permit. The availability of the contractor on site and the need for the additional volume of sand presents an opportunity to construct the protective beach berm to its design template in a cost-effective manner including addressing impacts of Hurricane Ian. The contractor's proposal is included with the draft Change Order from the City of Marco Island enclosed as Attachment C. Available funds including project contingencies could only cover the mobilization to the offshore borrow area and dredging a base amount of 25,000 cubic yards for placement on Sand Dollar Island. The City of Marco Island is requesting $650,400 to obtain the remaining 60,000 cubic yards of sand from the permitted offshore borrow area at a cost of $10.84/CY and placement on Sand Dollar Island. The unit cost of $10.84 /CY as proposed by the contractor is lower than the cost of past hydraulic dredging in Collier County or the region for similar type work. This sand will be used to complete constructing the protective berm on Sand Dollar Island as designed and address the impact of Hurricane Ian. The constructed berm will provide storm protection for the newly reopened flow channel connecting the southern lagoon at the County Park with the northern lagoon/gulf entrance, the associated Critical Wildlife Area, and the upland development. Constructing the Sand Dollar Island protective berm with significantly less volume than the design volume puts the system at higher risk for storm impacts and need for future maintenance sooner than planned. In addition, the cost of a near future maintenance project would be expected to be much higher than the cost proposed at this time with a contractor already on site. VI. Monitoring and Mitigation The City of Marco Island and Hideaway Beach Tax District are the project owner and plan to conduct monitoring required for the project. The project design did not require any mitigation. This request does not include funds for monitoring or mitigation. VII. Project Plans, Permits, etc. Project permit plans and listing of permits are enclosed as Attachment D 10 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island VIII. Summary The Tigertail Lagoon/Sand Dollar Island Ecosystem Restoration project is a City of Marco Island project designed to restore and protect a valuable ecosystem, recreational assets, and tourist attractions. The project incorporates improvements to aquatic and upland habitat while preserving and enhancing the resiliency of the natural system. The Florida Department of Environmental Protection in their permit review process determined that the project is in the public interest providing environmental, social and economic benefits and added storm protection. The project directly benefits Collier County Tigertail Beach Park in 4 main areas 1- Direct access to the gulf shoreline. Tigertail Beach Park represents one of the main public beach access points in Collier County and Marco Island in particular. At present the direct gulf shoreline at the north part of the Park has severely retreated in past few years with significant impacts post Hurricane Ian. Present conditions post Ian left no dry beach between the gulf and dune vegetation. This part of the Park gulf shoreline will be restored providing dry recreational beach and continuous access to the pristine shoreline of Sand Dollar Island which represents one of the main tourist attractions to this Park. 2- Water recreational activities. By restoring the 2-mile-long tidal lagoon, over water activities along the lagoon including kayaking, paddleboarding and other water recreational activities can resume. 3- Bird watching. One of the main attractions at the Park is bird watching. Restoring the ecosystem will maintain that function and prevent degradation of this attraction into the future. 4- Water quality and public safety. Restoring the tidal flushing of the lagoon at the park will help improve water quality and reduce public safety hazards. The Tigertail Lagoon/Sand Dollar Island Ecosystem Restoration Project design, permitting and construction window immediately post Hurricane Ian provided a timely opportunity to restore a system that otherwise was in rapid collapse. The additional funds requested from Collier County will provide direct public benefits that clearly encourage tourism within Collier County. 11 Humiston & Moore Engineers Tigertail Lagoon/ Sand Dollar Island Ecosystem Restoration Marco Island IX. Attachment A. Project Timeline Humiston & Moore Engineers Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Timeline • The project started with a feasibility study initiated by the City of Marco Island's Hideaway Beach Tax District in 2017 and completed in 2018. This study documented the impacts of Hurricane Irma and provided recommendations to engage all stakeholders to discuss system degradation and evaluate restoration alternatives. At the time, the Tax District thought that such a regional project to address the entire system was beyond its capabilities to permit, fund, and execute alone. They were also told by County staff that successful permitting would be very unlikely as the work was in the Big Marco Pass Critical Wildlife Area. • As a result, in 2019 Friends of Tigertail initiated and organized follow up discussions and public meetings with stakeholders and they included City of Marco Island, Collier County, FWC, and Audubon. • In July 2020 Friends of Tigertail made a presentation to inform the CAC on the deteriorating conditions and need for a restoration project. • In the Fall of 2020 as the system continued to deteriorate, Hideaway Beach re-engaged HM to develop a restoration plan and coordinate with stakeholders and agencies including the city, county, DEP, FWC, USACE, NOAA NMFS, FWS, Rockery Bay, and Audubon. • In January of 2021 Marco Island City Council unanimously supported pursuing permits to restore the system of Sand Dollar Island and Tigertail Lagoon. • Pre application meetings and coordination with all stakeholders, including Collier County, including Parks and Recreation, Coastal Zone Management, and administration in January 2021 • Permit applications on behalf of the City of Marco Island were submitted in April of 2021. • Commissioner LoCastro organized two Action Committee meetings of all stakeholders in mid- 2021 and early 2022 to get feedback on what should be done to address the conditions in the lagoon. • Permits by FDEP, USACE and FWC were issued between February 2022 and July 2022. • Marco Island City Council unanimously supported project construction and awarded the project to the selected contractor in September 2022. Project funding was provided by the City of Marco Island's Hideaway Beach Tax District. • In late September 2022 Hurricane Ian impacted the region and the project area. • Project construction started in November 2022 and Commissioner LoCastro organized another County and stakeholder meeting to review the project timeline. • Post Ian physical surveys were completed and, in December 2022, the City requested County funding support to supplement project construction because of Hurricane Ian impacts and additional sand volume needed to build the protective berm to design standards and to source that sand from off -shore.

Issuance of the joint coastal permit (JCP) would constitute a finding of consistency with Florida's Coastal Zone Management Program, as required by Section 307 of the Coastal Zone Management Act. Issuance of the JCP would also constitute certification of compliance with state water quality standards pursuant to Section 401 of the Clean Water Act, 33 United States Code (U.S.C.) 1341 I. PROPOSED ACTIVITY A. Project Description The proposed project is to establish a flow channel within the overwashed and shoaled areas of the Tigertail Lagoon and to restore the gulf -fronting shoreline of Sand Dollar Island using sediment hydraulically dredged from the flow channel and a sand trap at the north end of the island.. Additional sediment for berm placement may be sourced from the Hideaway Beach Nearshore and Offshore Borrow Areas. The proposed flow channel will have maximum allowable depth of -8.5 feet NAVD (in the north) and -5.5 feet NAVD (in the middle) and will not directly impact submerged aquatic vegetation (SAV). The proposed Sand Trap will have a maximum allowable depth of -9.0 feet NAVD. The proposed design berm will be approximately 150 feet wide with a 1H:15V (horizontal:vertical) sloped beach face and a submerged berm near Mean Lower Low Water (MLLW). The southern portion of the proposed flow channel, also called the distribution channel, is not authorized and will require a permit modification because its final dimension or configuration will be dependent upon conditions at the time of construction. The activity includes consideration of an application for a 15-year sovereign submerged lands easement (No. 42667) containing 26.13 acres, more or less, for the proposed sand trap. The activity will also require an Incidental Take Authorization from Florida Fish and Wildlife Conservation Commission for its potential impact to state listed bird species. B.

III. BACKGROUND/BASIS FOR ISSUANCE A. Background Information Sand Dollar Island is a narrow low lying semi -enclosed peninsular, which was formed as result of the long term migration of the Big Marco Pass ebb shoal east towards the mainland and eventually attaching to Marco Island at its southern end. The Tigertail Lagoon /Sand Dollar Island system (TLSDI) consists of a tidal lagoon that was formed behind the peninsular at the south end (Tigertail Lagoon) with the mouth of the system at Hideaway Beach and Big Marco Pass at the north end. The lagoon is connected to the Gulf of Mexico by a narrow flow channel that runs between Marco Island and Sand Dollar Island. Over time the spit has been reshaped by storm events and general wave hydrodynamics resulting in frequent overwash of the central segment, landward migration of the mouth and shoaling of Tigertail Lagoon. These events have led to the systematic reduction of the width of the mid -section of the lagoon, causing severe restrictions to tidal flow, which is causing loss of lagoon habitat. Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 4 of 20 To prevent the attachment of Sand Dollar Island to the mainland, which could result in a stagnant lagoon system, the entrance to the TLSDI system at Big Marco Pass, is periodically dredged under Permit No. 0309260-010-JM (the Hideaway Beach Nearshore Borrow Area). This proposed project will further enhance the flushing of the lagoon by establishing the flow channel; minimizing overwash and shoaling by restoring and maintaining the berm at a pre -Irma configuration; and further minimize the rate of landward migration of the spit by creating and maintaining the sand trap. Thus, restoring and enhancing aquatic and upland habitats within the coastal ecosystem of TLSDI that have deteriorated overtime. B. Habitats Hardbottom/Coral Reef Surveys conducted in 2018 and 2020 for the Hideaway Beach Nourishment and Groins project (File No. 0309260-010-JM) documented small sponges and octocorals growing on shell hash substrate adjacent to the proposed sand trap (i.e., adjacent to the nearshore borrow area between H-6 and H-7, and near H-12,). The project is not expected to directly impact hardbottom resources and secondary impacts are not predicted to occur. Submerged Aquatic Vegetation Surveys in 2017, 2018, and 2020, showed that submerged aquatic vegetation (SAV) in the project area consists mostly of Halodule wrightii, with some Halophila decipiens. Several genera of macroalgae (e.g., Caulerpa spp. and Penicillus spp.) were observed as well. SAV in the northern portion of the project has been monitored previously for the Hideaway Beach Nourishment and Groins project (File No. 0309260-010-JM). Recent SAV surveys conducted in 2020 and 2021 included the SAV habitat along the interior of Sand Dollar Island from the mouth of the system at Hideaway Beach (H-12) to the southern end of Tigertail Lagoon (R-135). In 2020, the SAV bed between H-4 and H-7 was predominately composed of H. wrightii and H. decipiens. Historically, SAV has been documented in the proposed flow channel dredge area between H-1 and H-4; however, surveys conducted in 2020 and 2021 did not find any benthic resources within this portion of the dredge template. In 2021, sparse coverage (0-15%) of SAV was present east of the proposed flow channel dredge template between R-128 and R-130. Between R-129.5 and R-131.5, the areal extent of SAV has been receding over recent years as the Sand Dollar Island migrates landward. Moderate to dense coverage (25-100%) of SAV was observed between R-131 and R-133. In southern Tigertail Lagoon, SAV beds were present in 2018, 2020, and 2021 surveys along the shallow perimeter of the lagoon; in 2021, these beds ranged in coverage from sparse (0-24%) to dense (50-85%). Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 5 of 20 Realigning the barrier island to 2017 conditions and further opening the waterway behind the Sand Dollar Island is proposed to increase flushing and prevent Tigertail Lagoon from being closed off from the surface waters of the Gulf via the northern lagoon. Dredging of the flow channel restoration area will be limited to the over -washed area to avoid SAV resources. Furthermore, the narrow distribution channel proposed from R-131.5 to R-133 would be hand dug/dredged to ensure SAV resources in this area are avoided to the maximum extent practicable. Though the project is not expected to directly impact SAV and secondary impacts are not predicted to occur, the proximity of SAV habitat to the proposed flow channel dredge template indicates these resources are within areas potentially under the influence of the project. As such, the permit will require SAV to be monitored to provide the Department with reasonable assurance that any unpermitted project -related impacts to resources will be documented if they occur. Pre -construction monitoring will be required to document current distribution of benthic resources within the influence of the project, and the dredge contractor will be required to use resource maps from the pre -construction survey to avoid resources. The biological monitoring section (Section K) expands on the details of the monitoring that will be required by the permit. Additionally, a Biological Monitoring Plan has been approved by the Department and will be attached to the permit. The Plan, which will be a binding part of the permit, specifies monitoring procedures for SAV. Should unpermitted project -related impacts to SAV resources occur, mitigation will be required. Mangrove and Marsh Vegetation Mangroves and marsh vegetation are present along the fringe of the lagoon shoreline. In the northern portion of project, salt marsh habitat is present on the landward side of Sand Dollar Island. Mangroves line much of the eastern portion of the waterway from R-128 to R-131.5. Current trends of beach migration shoreward suggest that without intervention the beach may fuse to the inland shoreline in this area. The proposed project will widen the waterway adjacent to mangroves, thereby maintaining hydrological connection to this habitat. South of R-131.5, mangroves are present on both sides of the waterway. Mature mangroves line a large portion of the Tigertail Lagoon. The mangrove community includes red (Rhizophora mangle), white (Laguncularia racemose), and black (Avicennia germinans) mangroves. Monitoring will be required to ensure the proposed project does not impact mangrove or marsh habitats. Beach The beach, swash zone and surf zone of the project area is comprised of soft sandy bottom. The sandy substrate in the subtidal, intertidal and supratidal portions of the beach is an important habitat for invertebrates living on (epibenthos) or within (infauna) the sediment. This invertebrate community can include crabs, polycheates, gastropods, and bivalves. The infaunal organisms are important food items for shorebirds and fish. Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 6 of 20 The infauna inhabiting the beach placement area will be buried by the project. This burial will temporarily eliminate the infaunal population within the placement area, but recolonization from adjacent beaches is expected to begin immediately. Studies have shown that beach, swash zone and surf zone populations of infauna will rebound to pre -nourishment levels within a year of construction if the fill material is similar to the existing beach sand. Sand Dunes Dune vegetation in the proposed beach restoration area has sparse coverage which is suitable for nesting shorebirds. To maintain the low cover of vegetation, monitoring will be required to estimate percent cover of dune vegetation for adaptative management purposes. If the percent cover exceeds 10% total cover or if sandbur (Cenchrus spp.).) recruitment is noted, then the regulatory agencies will be notified immediately for adaptive management. C. Protected Fish & Wildlife Pursuant to the Environmental Resource Permit Applicant's Handbook, Volume I, 10.2.7(b), in evaluating whether the proposed activity will adversely impact the ecological value of uplands to aquatic or wetland dependent listed species that nest in upland, such as marine turtle and shorebirds, and to maintain consistency with the authority of the Florida Fish and Wildlife Conservation Commission (FWC) under Florida's Coastal Zone Management Program, the Department considered comments received from the FWC and the U.S. Fish and Wildlife Service (FWS). Pursuant to the Environmental Resource Permit Applicant's Handbook, Volume I, 10.3.1.5, mitigation can include the implementation of management plans, or other measures, such as the Terms and Conditions and the Reasonable and Prudent Measures from the FWS Biological Opinion, as well as the recommended conditions from the FWC. These requirements will be incorporated into the permit. Turtles The beaches in Collier County provide potential nesting habitat for threatened loggerhead (Caretta caretta) and green (Chelonia mydas) marine turtles. Placement of sand on a marine turtle nesting beach can impact nesting females, their nests, and hatchlings due to modifications of the profile and incubation substrate relative to the native beach. Nesting females may respond to these changes by an increase in non -nesting emergences (false crawls), a decrease in the number of nests deposited, or a shift in nest site selection across the profile. Altering the incubation substrate can also affect the female's decision to nest, as well as the hatch and emergence success for the nest In accordance with 161.041(5), F.S., no construction that could result in take of threatened and endangered marine turtles and shorebirds shall begin until the required federal incidental take authorizations are issued in accordance with the federal Endangered Species Act. In the event that additional or different requirements from the permit conditions are specified in Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 7 of 20 the U.S. Fish and Wildlife Service (FWS) Incidental Take Authorization and Biological Opinion, additional marine turtle protection conditions shall be incorporated into the permit through a modification Additionally, no relocation of marine turtle nests shall occur unless specifically authorized by the FWC in a permit issued pursuant to Florida Statute 379.2431(1) and Rule 68E- 1, F.A.C. Therefore, in accordance with Florida Statute 379.2431 (1), FWC has included marine turtle protection conditions in the draft permit. Birds The project is located within the Big Marco Pass Critical Wildlife Area (CWA). First established in 1988, this CWA provides protection for nesting and foraging seabirds, shorebirds, and wading birds. The CWA consists of the emergent island, mudflats, and lagoon along the northwestern edge of Marco Island. This CWA has historically supported large colonies of nesting black skimmers and least terns, along with solitary nesting pairs of Wilson's plovers and killdeer. Nesting occurs along the northern half of the CWA, comprised of a mosaic of open sandy beach and sparse dune vegetation. Resident and migratory seabirds, shorebirds, and wading birds rely on the area for roosting and foraging along the shoreline and flats of the lagoon. Portions of the CWA are posted closed each year under state rule (68A-19.005 F.A.C.) to prevent disturbance to nesting and foraging birds. Entry into any CWA posted areas would require additional authorizations from the FWC. Portions of the proposed project site are located within an area that supports beach - nesting birds, including black skimmers and least terns which are both state listed as Threatened. The excavation of 130,000 cubic yards of sediment for construction of the sand trap at the north point of Sand Dollar Island is likely to result in take via significant habitat modification for these species. Construction in proximity to breeding sites can also cause take by interfering with nesting success, including mortality of eggs, chicks, and fledglings due to disturbance from heavy equipment and construction. The project area is also within the FWC-designated Reddish Egret Core Foraging Area. Loss or degradation of suitable foraging habitat within Core Foraging Areas can result in take via significant habitat modification because suitable foraging habitat is limited for this species. The proposed flow channel on the back side of Sand Dollar Island has the potential to result in take via significant habitat modification for this species. The FWC has determined that the proposed project will result in Take of State -Listed Threatened species as defined by Chapter 68A-27.001, F.A.C, and that an FWC Incidental Take Permit (ITP), as defined by Chapter 68A-27.007, F.A.C., will be required. The Florida Fish and Wildlife Commission has additional authority under Chapter 379, F.S. to protect upland habitat used by shorebirds. Manatees Florida manatees (Trichechus manatus latirostris) inhabits the waters of Collier County year round. Use of this area is documented by aerial, telemetry, and mortality data. Manatee Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 8 of 20 aerial survey data indicate that manatee distribution in this county is widespread, and they exhibit an array of activities in the county including traveling, resting, feeding, and cavorting (mating). Tigertail Lagoon /Sand Dollar Island system is located in an area designated as Important Manatee Area (IMAs) per the Effect Determination Key for the Manatee in Florida. As a protective measure, the draft permit will require that the FWC Standard Manatee Conditions for In -Water Work be followed during construction in all project areas. Additionally, since the proposed project falls within an IMA, the draft permit will require dedicated protected species observers and limit nighttime clamshell dredging. D. Other Criteria Public Health, Safety or Welfare The proposed restoration project will help to improve water flow within the lagoon, reduce the potential for overwashing and subsequent shoaling within the lagoon, which may reduce the potential for adverse impacts to public health, safety or welfare to occur, should the lagoon become stagnant. Property of Others The proposed project is expected to maintain the functionality of the existing mangrove shoreline and related habitats adjacent to the overwashed areas; thus naturally reducing the potential future vulnerability of upland property. The proposed project is not expected to adversely affect the property of others., Additionally, it is not expected to unreasonably infringe upon the traditional, common law riparian rights, of upland property owners adjacent to sovereignty submerged lands. Navigation The project is expected to remediate harmful shoaling within the lagoon. Other than any possible restrictions to navigational access on a temporary basis during dredging, the proposed project is not expected to adversely affect navigation. Recreation The restoration and maintenance of the TLSDI will allow continued use by the public for observation of wildlife, picnicking, sunbathing, swimming, surfing, recreational fishing, and related activities. Historical and Archaeological Resources Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 9 of 20 In their letter dated April 21, 2021 (DHR Project File No. 2021-2317), the Florida Division of Historical Resources (DHR) presented the findings of their Due Diligence review for the proposed project. They determined that the proposed activities are unlikely to affect historic properties. Nevertheless, General Condition 10, included in the draft permit, establishes a protocol in the case of unexpected fortuitous find. E. Water Quality The proposed project includes the dredging of the flow channel and the sand trap, with placement of sediment on the gulf -fronting Sand Dollar Island. Additionally, sediment may be dredged from the previously authorized Hideaway Nearshore and Offshore Borrow Areas. The proposed flow channel dredge area lies within Class III waters of the Tigertail Lagoon. Mangroves and SAV are located in the vicinity of the proposed flow channel dredge area. All dredging will avoid direct impacts to mangroves and SAV in the area. Additionally, because of the presence of SAV resources adjacent to the dredge/excavation area, the mixing zone within this dredge area will be truncated at the edge of the adjacent resources. Therefore, during dredging of the flow channel, turbidity will be monitored at the edge of the 150-meter mixing zone or nearest downdrift SAV edge to ensure compliance with the State Water quality standard (29 NTUs above background). The majority of the proposed sand trap is located within an accretional area of the Rookery Bay Aquatic Preserve and is subject to the antidegradation requirements of Rule 62- 4.242, F.A.C. This Rule 62-4.242(2)(b)2., F.A.C., allows for some deviations from background to account for natural fluctuations in turbidity levels at the site. By measuring the natural background variability of turbidity over one tidal cycle, adjacent projects have demonstrated that background turbidity levels naturally fluctuate by at least 3 Nephelometric Turbidity Units (NTUs) in the vicinity of the proposed project in the Rookery Bay Aquatic Preserve. Therefore, during dredging of the sand trap, turbidity will be monitored at the edge of the 150-meter mixing zone to ensure compliance with the antidegradation threshold (3 NTUs above background). The proposed Sand Dollar Island Restoration Area lies along Class III waters of the Gulf of Mexico. The proposed sediment disposal work will be accomplished in a manner that minimizes the potential for elevated turbidity. Pursuant to Rule 62-4.244(5)(d), F.A.C., best management practices will be implemented to minimize the magnitude and duration of turbidity to the maximum extent practicable. Therefore, during sediment disposal, turbidity will be monitored at the edge of the mixing zone polygon (150 meters offshore by 1000 meters down current) to ensure compliance with the State Water quality standard (29 NTUs above background). Pursuant to Rule 62-4.242 (2)(a)2.b. F.A.C., the Applicant has requested an extension of the thirty -day time period in which elevated turbidity levels may occur within a mixing zone that Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 10 of 20 is located in an OFW. Since the Applicant has demonstrated that the work cannot be completed in 30 days, and that no adverse impacts are expected to occur as a result of the requested time extension, the Department intends to grant the extension The proposed project may result in improved water quality within the Tigertail Lagoon system. Water quality monitoring of additional parameters (other than turbidity) will be required to document changes to water quality within the influence of the project. The protocols for the additional water quality assessment will include data collected at quarterly discrete sampling stations and also by continuous sampling using a datasonde. The draft permit will outline the water quality monitoring protocol required to provide reasonable assurance that project activities do not violate the State's water quality standard, the antidegradation allowance nor adversely impact the adjacent SAV or mangrove communities. F. Sand Quality Pursuant to Rule 6213-41.007(2)(j), F.A.C., to protect the environmental functions of Florida's beaches only beach compatible fill shall be placed on the beach or in any associated dune system. Beach compatible fill is material that maintains the general character and functionality of the material occurring on the beach and in the adjacent dune and coastal system. A sediment quality assurance /quality control (QA/QC) plan that provides reasonable assurance that the sediment from the borrow areas will meet the standard in Rule 6213- 41.007(2)0), F.A.C., was submitted with the application The sediment compliance values are included in the Sediment QA/QC Plan (dated September 21, 2021), which will be incorporated into the final permit by reference. The Department requires compliance with this plan. G. Coastal Engineering Pursuant to Rule 62B-41.005(3), F.A.C., the Department has received adequate engineering data concerning the existing coastal system and the design features that is sufficient for an evaluation of the proposed activities. The department received the Engineering Management Plan, prepared by Humiston & Moore Engineers, dated April 5, 2021. Pursuant to Rule 62B-41.007(2), F.A.C., the proposed project is designed in accordance with generally accepted coastal engineering standards and practice. In accordance with the definition provided in Rule 62B-36.002(4), F.A.C, or the provisions of sub -section 161.101(3), F.S., the project area is not designated as critically eroded beach. The activity as proposed is not beach restoration defined as the placement of sand on an Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 11 of 20 eroded beach for the purposes of restoring it as a recreational beach and providing storm protection for upland properties, pursuant to subsection 161.021(4), F.S. The proposed addition of the gulf -front segment of Sand Dollar Island as a placement site for the dredged material from the inlet -fronting segment of Sand Dollar Island is not expected to have an adverse impact to the Big Marco — Capri Pass Complex, and is consistent with Section 161.142(1), F.S. The project monitoring data has not indicated adverse effects from dredging the permitted nearshore borrow area. The proposed northeastward extension of the borrow area will be leeward of the ebb shoals of the Big Marco and Capri Pass Complex where it will be aligned with the tidal currents and further sheltered from ocean waves. Consequently, the borrow area extension is not expected to result in adverse effects to inlet tidal hydraulics or increase erosion of Hideaway Beach. The project monitoring demonstrates migration and accretion of beach -compatible sand into the proposed borrow area extension; hence, detailed information concerning the material to be excavated and analysis of the compatibility of the material with the respective placement sites is not required from the applicant. Furthermore, a sediment quality assurance/quality control plan is not required as a specific condition for approval of the permit. Pursuant to Rule 62B-41.005(2), F.A.C., coastal construction authorized by the Department shall have a net positive benefit to the coastal system resulting from the project's effects, as demonstrated by the Applicant, taking into account the considerations and requirements of Section 161.041, F.S. The removal of sand from the borrow area will likely reduce sediment transport toward the Collier Creek entrance, and thereby, minimize shoaling and maintenance of the navigation channel. The transfer of sand from the borrow area to the gulf - front segment of Sand Dollar will supply sand to the Marco Island as waves and tides transport the sand to the downdrift beaches. H. Impact Minimization The Applicant has provided reasonable assurance that measures will be taken to minimize any potential adverse impacts to the maximum extent practicable. During the permit application process, the proposed sand trap acreage was reduced to reduce the potential impact on shorebird nesting habitat. Additionally, the project design and the size of the mixing zone were adjusted to avoid impacts to SAV. During sediment disposal, the Applicant will employ best management practices (BMPs) to minimize turbidity and will monitor in accordance with FWC recommendations and the sediment QA/QC plan to minimize potential impacts to marine turtles and shorebirds. A turbidity allowance of 3 NTUs above a corresponding background sample will be used for work within the OFW pursuant to the antidegradation rule. The dredge/excavation sediment has a similar grain size as the existing beach and is expected to maintain the general Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 12 of 20 environmental character and functionality of the material on the native beach. This will be conducive for marine turtle nesting and promote rapid recovery of the infauna community. No impacts to SAV, hardbottom, or mangroves / marsh will be authorized by the permit; therefore, avoidance and minimization measures will be required to be implemented during construction to minimize potential unauthorized impacts to natural resources. These measures include restricting the mixing zone to the edge of the nearest SAV bed, prohibiting anchoring or storage of equipment within SAV beds, establishing a no -work zone (10-meter buffer) around SAV resources, and requiring all work near (within 30-meters of) resources to be reported. SAV monitoring will also be required to document any unauthorized proj ect-related impacts, if they occur. Pre -construction mapping and monitoring will be required to provide the contractor with maps of benthic resources, and the Applicant will be required to instruct their contractor to use these maps to avoid resources. Additionally, a portion of the proposed dredged channel (i.e., the distribution channel) will be hand dug to reduce the potential for impacts to adjacent SAV resources. The narrow distribution channel will not be excavated until the Permittee has provided updated drawings and current SAV survey information to the Department for approval through a permit modification. I. Sovereign Submerged Lands A letter of consent will be required for the dredging of the flow channel and the distribution channel as well as the disposal of sediment on sovereign submerged lands. A public easement will be required for the creation and subsequent dredging of the sand trap. An erosion control line will not be established at the sediment disposal site on the gulf -front segment of Sand Dollar Island area because the area is not contiguous with upland property, the uplands areas of Sand Dollar Island are State owned and the site is not on a critically eroded beach. Pursuant to Rule 18-21.004(3)(a), F.A.C., the proposed project is not expected to unreasonably infringe upon the traditional, common law riparian rights, as defined in Section 253.141, F.S., of upland property owners adjacent to sovereignty submerged lands; because the activity will not impede access to, or view of the water. Additionally, pursuant to Rule 18- 21.003(53), F.A.C., the proposed project would be in the public interest because the activity provides demonstrable environmental, social, and economic benefits, by maintaining a navigable waterway, and providing more storm protection, without causing any significant environmental harm. Pursuant to Rule 18-21.004(3)(b), F.A.C., satisfactory evidence of sufficient upland interest is not required for activities on sovereignty submerged lands that are not riparian to uplands, or when a governmental entity conducts restoration and enhancement activities, provided that such activities do not unreasonably infringe on riparian rights. In this case, the sand placement site on the gulf -front segment of Sand Dollar Island area is not contiguous with upland property and the uplands areas of Sand Dollar Island are State owned, so sufficient upland interest is not required Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 13 of 20 The proposed project is expected to maintain this environmental and recreational resource so that the public may continue to enjoy traditional uses of the TLSDI system, including but not limited to, boating, fishing and swimming. Removing the overwashed sand from the lagoon will restore natural habitat and return the biological and recreational value of the area. The disposal of sediment on the berm will also restore and maintain nesting habitat for marine turtles and shorebirds. The proposed project is not expected to impact SAV resources or generate a significant amount of turbidity, so it will not interfere with the propagation of fish and wildlife. Additionally, the Florida Department of State's Division of Historical Resources evaluated this project and determined that no cultural resources will be affected by this project. After considering all the factors listed above, the Department has determined that the project is expected to meet the Sovereign Submerged Lands criteria in Rule 18-21.004(2), F.A.C. J. Mitigation The draft permit does not authorize direct or secondary impacts to benthic resources. Mitigation will only be required if adverse, unauthorized, project -related impacts occur. The proposed project may result in improved water quality and subsequent expansion of SAV in Tigertail Lagoon. Water quality monitoring will be required to document changes to water quality. If improvements in water quality and/or SAV expansion are demonstrated, the Department may evaluate these improvements for lift (pursuant to Rule 62-345, Uniform Mitigation Assessment Method) as potential compensatory mitigation if needed. The FWC has determined that the proposed project will result in Take of State -Listed Threatened species as defined by Chapter 68A-27.001, F.A.C, and that an FWC Incidental Take Permit (ITP), as defined by Chapter 68A-27.007, F.A.C., will be required. The ITP will include mitigation measure to offset take incurred by the proposed project. K. Monitoring Biological monitoring will be required to document any potential unauthorized impacts to natural resources. The Applicant will be required to provide the construction contractor with an accurate map of benthic resources in the project area prior to commencement of construction so that impacts can be minimized to the greatest extent practicable. Monitoring will include the in - situ delineation of the edge of benthic resources, as well as qualitative and quantitative measurements of SAV and mangrove resources pre and post construction. Dune vegetation monitoring will be conducted to inform adaptive management plans. If the coverage of dune vegetation exceeds 10% total cover or sandburs are documented, adaptive management will be employed which may include the removal of dune vegetation. Water quality monitoring for turbidity will be conducted during construction to ensure that water quality standards are being met. The turbidity monitoring contractor will be Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 14 of 20 independent of both the design contractor and the construction contractor. Additional water quality monitoring will be conducted to document potential water quality improvements in Tigertail Lagoon due to increased flushing that may result from the proposed project. All biological monitoring will be conducted according to the Department -approved Biological Monitoring Plan (Approved December 20, 2021), which details the monitoring parameters, methods, schedules, and reporting requirements for the project. The approved Biological Monitoring Plan will be a binding part of the permit. See the approved Biological Monitoring Plan and the draft permit for specific information on monitoring of SAV, mangroves and marsh, dune vegetation, and water quality (except turbidity), and deliverable submittal requirements. Sediment quality at the nourished beach will be monitored in accordance with the approved sediment QA/QC plan. Per FWC guidelines, the draft permit will include pre, during, and post construction monitoring for marine turtles and shorebirds. No physical monitoring plan is being required on the proposed project. However, as built bathymetric surveys of the dredge locations will be required post construction to verify avoidance of SAV impacts. L. Public Interest Regulatory As discussed in the sections above, the Department has considered the effects of this project according to the public interest criteria that are specified in Section 373.414(1), F.S., and the Environmental Resource Permit Applicant's Handbook, Volume I, 10.2.3. The following is brief summary of that evaluation for each of the public interest criteria: • The activity will have a positive effect on public safety and public welfare, and is not expected adversely affect the property of others; • The activity is not anticipated to adversely affect the conservation of fish and wildlife, including endangered or threatened species, or their habitats; • The activity is intended to offset harmful shoaling and erosion; • The activity is not anticipated to adversely affect the fishing or recreational values or marine productivity in the vicinity of the activity; • The proposed construction activity will be of a temporary nature; • The activity will not adversely affect significant historical and archaeological resources under the provisions of s. 267.061; and Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 15 of 20 • The current condition and relative value of functions being performed by areas affected by the proposed activity in whole will generally be improved by the project. After weighing the effects of the project for each of these criteria, and based on reasonable assurance provide by the Applicant, the Department has determined that the proposed activity is clearly in the public interest. Proprietary The proposed project will reduce the potential for overwash, relieve the shoaling within the lagoon, thereby improving flushing within the lagoon maintaining the aquatic and upland habitats within the TLSDI system. Therefore, pursuant to Section 161.088, F.S., the proprietary authorization for this project is in the public interest. The project will not adversely affect fish and wildlife habitat or other natural or cultural resources and will not interfere with traditional recreational uses such as fishing, boating, and swimming. Pursuant to Rule 18-21.003(54), F.A.C., the demonstrable environmental, social, and economic benefits which would accrue to the public at large as a result of this activity would exceed all demonstrable environmental, social, and economic costs of the proposed action. Therefore, pursuant to Rule 18-21.004(1)(a), F.A.C., the Department has determined that this project is in the public interest. M. Specific Regulatory Basis for Issuance The Applicant has provided affirmative reasonable assurance that the construction of the activity will comply with the provisions of Part IV of Chapter 373, F.S., and the rules adopted thereunder. The Department has considered the direct, secondary and cumulative impacts of the project, as well as the general and specific conditions to the attached draft permit, in making this determination. Specifically, construction of the activity will not result in violations of water quality standards, nor will the construction activities degrade ambient water quality in Outstanding Florida Waters pursuant to Rule 62-4.242, F.A.C., other than turbidity within the approved mixing zone, pursuant to Section 373.414(1), F.S., and set forth in Chapters 62-4 and 62- 302, F.A.C.. The Applicant also has demonstrated that the construction of the activity is clearly in the public interest, pursuant to Paragraph 373.414(1), F.S. Also, pursuant to Rule 62-4.242 (2)(a)2.b., F.A.C., the Applicant requested an extension of the thirty -day time period for water quality degradation in an OFW. Although the rule limits water quality degradation within an OFW to a period of thirty days, it also offers the Department some discretion. The Department may allow an extension of time, in which construction -caused degradation may occur within a defined mixing zone, if the Applicant can demonstrate that the extension is unavoidable, and that suitable management practices and technology will be employed to minimize any degradation. Given the nature and scale of this beach restoration project, it would be impossible to complete the work within thirty days. Also, the Applicant proposes to use best management practices for controlling turbidity at the dredge site. Therefore, Consolidated Notice of Intent to Issue File No. 0401778-001-JC Tigertail Lagoon / Sand Dollar Island Ecosystem Restoration Project Page 16 of 20 pursuant to Rule 62-4.242(2)(a)2.b. F.A.C., the Department intends to allow for a temporary elevation of turbidity, within the mixing zone, for a period not to exceed 120 days. The Applicant has also provided adequate engineering data to evaluate the design features of the project and any potential effects to the coastal system. Pursuant to Chapter 161, F.S., the Department finds that the proposed activities: • will not result in any significant adverse impacts to the sandy beaches of the state; • are not expected to adversely impact nesting marine turtles, their hatchlings or their habitat; • will not interfere, except during construction, with the use by the public of any area of the beach seaward of mean high water; and • are appropriately designed in accordance with Rule 6213-41, F.A.C. N. Specific Proprietary Basis for Issuance The Applicant has met all applicable requirements for proprietary authorizations to use sovereign submerged lands. That includes the requirements of Article X, Section 11 of the Florida Constitution, Chapters 253 and 258, F.S., associated Rules 18-21 and 18-20, F.A.C., and the policies of the Board of Trustees. Therefore, the Applicant has provided reasonable assurance that the proposed activity would: • be in the public interest; • maintain essentially natural conditions; • not cause adverse impacts to fish and wildlife resources or public recreation or navigation; and • not interfere with the riparian rights of adjacent property owners. IV. PUBLICATION OF NOTICE The Department has determined that the proposed activity, because of its size, potential effect on the environment or the public, controversial nature, or location, is likely to have a heightened public concern or likelihood of request for administrative proceedings.
