Once destabilized, these invaluable coastal resources can be lost. Adoption of a CCCL establishes an area of jurisdiction in which special site and design criteria are applied for construction and related activities. Due to the severity of coastal storms, these standards are oftentimes more stringent in beach zones, as opposed to protected coastal property farther inland. The Coastal Construction Control Line (CCCL) Program regulates structures and activities which can cause beach erosion, destabilize dunes, damage upland properties, or interfere with public access. CCCL permits also protect sea turtles and dune plants. The Coastal Construction Control Line (CCCL) Program is an essential element of Florida's coastal management program, protecting Florida's beaches and dunes while ensuring reasonable use of private property. CCCL Locator The CCCL locator is provided online by the Florida Department of Environmental Protection. The link as of 2022 is: https://ca.dep.state.fl.us/mapdirect/?webmap=a8c9e92fbad5446d987a8dd4ee5 dc5cc (ECL) EROSION CONTROL LINE Erosion Control Line: The Erosion Control Line establishes the boundary of upland ownership by the state when a beach restoration project is constructed. Courts have ruled sand added to the beach seaward of the ECL is owned by the state and held in trust for the public. It was established based on the location of the Mean High Water Line, or MHWL, at the time of construction. However, landowners retain the right to have access to the water, the right to reasonable use of the water, the right to accretion and reliction, and the right to the unobstructed view of the water. In other words, the ECL is the fixed property line between private and public lands. A landowner does not own this part of the beach in front of the property and the land seaward of this line does not convey with a sale of the adjacent upland parcel. Statement of Purpose for a Dune Masterplan: Dunes are part of Florida's coastal ecosystems, providing economic, environmental and recreational benefits to the local community. Our beaches contribute greatly to the economy and employment within the City of Sunny Isles Beach, attracting roughly a million visitors annually and contributing billions to the local economy each year. A healthy dune system is an invaluable asset -to coastal communities like Sunny Isles Beach. Coastal dunes are also habitat for wildlife and support a high biodiversity of flora and fauna. Sunny Isles beaches provide nesting grounds for threatened and endangered 'sea turtles, and serve as an important habitat for shorebirds and other wildlife. Functional dune systems keep beaches healthy by accreting sand and minimizing beach erosion rates. Established dunes also protect coastal infrastructure and upland properties from storm damage by blocking storm surge and absorbing wave energy, thereby protecting property values. Obiectives: The Dune Masterplan (the Plan) is intended to outline a management approach that addresses improvements to both existing dune features and new dunes and protects existing dunes. The entire beach has been evaluated, and the dunes categorized by physical/geographic characteristics and existing conditions. The Plan should focus on fostering projects that can have both immediate and long- term benefits, while also developing a feasible program in terms of design, permitting and maintenance by: • Restoring and expanding the existing dune system. • Preventing dune loss and beach erosion. • Creating a long-term maintenance plan for the dune system. • Engaging coastal property owners to improve their privately managed dune system. • Increasing public education and awareness of the importance of dune restoration and maintenance. • Creating or modifying existing and new dune access points at 45 -degree angles to minimize storm surge damage. • Identifying funding for dune restoration projects. • Planning for the impacts of sea level rise. • Restoring existing dunes to their original boundaries. • Creating a maintenance standard and schedule for all dunes. • Prioritizing new dune locations for storm protection, enhancing ecology/aesthetics and increasing property values. • Providing typical topographic design profiles for new dunes. • Establishing a native salt tolerant vegetation palette. • Mandating future beach construction to follow the guidelines stipulated in this plan. The Plan should be used as a guide in the City's efforts in managing the urban, man-made dune system as close to a natural system as possible, with the intent of ensuring the dunes provide storm protection, erosion control, and a biologically -rich habitat for local species. The City Manager (or designee) should assign the inspections of the dunes to o specific City department. Background The City of Sunny Isles Beach marine shoreline and beach is located within Miami -Dade County, which is bordered by Golden Beach to the North and Haulover Beach to the South. Below is a detailed map of the city jurisdiction. I , e I Dune Cross Section DUNE CROSS SECTION Coastal Strand Pioneer Wrack Florida Hammock Zone Zone Zane lino Roof Tract Present Ecoloeical Condition The City of Sunny Isles Beach has a narrow and fragmented dune system with varying levels of functionality. The entire dune system is held in trust by the State of Florida. However, the City manages the dunes at Samson Beachfront Park and Pier Park. All other dunes have been managed by adjacent private property owners. (Committee input needed) Future Conditions Locally, the Southeast Florida Regional Climate Change Compact (SFRCCC) has adopted, and routinely updates, a unified sea level rise projection for the Southeast Florida region that includes Miami -Dade County. The unified sea level rise projections are as follows: • Short term: 10 to 21 inches of sea level rise by 2040 • Mid-term: 21 to 54 inches of sea level rise by 2070 • Long-term: 40 to 136 inches of sea level rise by 2120. 2019 Sea level rise projections are shown below: 175 NOAA Extreme 1:6 NOAA High ' 92 NOAA i' Intermediate High u Z v 40 Observed Unified Sea Level Rise Projection 200 (Southeast Florida Regional Climate Change Compact, 2019)' 17 lPCC NOAA Intermediate NOAA High 06180 Year Median _ 0 — LL o (Inches) ( High (inches) N 2090 2100 2110 2120 Inches 1 w 160 CLIMATE CHANGE - 3 2040 10 17 21 > 140 x2070 21 4054 120 ...- L a M w N v1 2120 40 92 136 a100 - - - ------- —--- --------- - ---- u 50 Year Planning Horizon w J o 80 6 rn .�— 60 a � 175 NOAA Extreme 1:6 NOAA High ' 92 NOAA i' Intermediate High u Z v 40 Observed 40 40 IPCC Median or V 5 -Year Average 17 �- 20 Mean Sea Level O I 21 _ 0 — 10 1990 2000 2010 2020 2030 2040 2050 2060 2070 2080 2090 2100 2110 2120 Year CLIMATE CHANGE - Future changes in sea level rise will also affect the intensity and scale of storm surges from tropical storms and hurricanes. Higher sea levels can cause storm surges to travel farther inland than in the past, causing damage to shorelines and increasing coastal erosion. The combined impacts of these events in the Southeast U.S. region have the potential to cost up to $60 billion per year by 2050. Design and Maintenance of the Dune System To create this plan, the existing beach/dune conditions were evaluated utilizing information obtained from onsite reconnaissance and aerial photography to review. The varying conditions of the existing dune were considered to establish different categories. These categories are based on the presence/health of dune vegetation, continuous dune formation, width of the vegetated dune, and overall beach management goal of establishing a consistent City dune system for storm protection value, habitat health, resilience, and aesthetic value. These categories (as shown on the following aerials) and their associated conditions are the basis for the differing recommendations for the long-term management. The categories have been broken down as follows: • Properties with NO Dunes • Properties with Dunes that Need to be Restored or Reconfigured • Properties with a Functioning Dune with Minimal Exotic Infestation • City Properties With or Without Functioning Dune • Properties with Chronic Erosion or Dune Installation not Feasible (No picture available) Pictured below is an infographic detailing the properties along the City coastline, complete with corresponding dune classifications based on the dune criteria. kiry p \SLE It-Al;c City of Sunny Isles Beach Beach Corridor - Regalia, Ocean One, Ramada Plaza Marco Polo, & Ocean Two Legend City Limits - Construcdon Con act Line Erosion Control Lire Dune Classification No Dune ._i Duna needs b be restored or rswn fgured Dune that is functional or nor functional on cityproparty {t Functionaldune•withminimal exotioinfeatation Chroniooreporadio erosion orduna installation not waabN 0 37.5 75 150 Feet Date 09.1-2022 Map: A0029 \5LEJ N to. - City of Sunny Isles Beach Beach Conidor- Ocean Two, Miami Beach Club, Residences by Armani Casa & Ocean Three Legend City Limits — Construction Control Line Erosion Control Line Dune Classification No Dune Cune n= -ads tDb=_ restore -d or r=Donfgured Dun=_ that is functional or non-functional on cityproparty Funotionaldunewithminimal axotioinfestalion i Chronioorsporadioerosion ordune installation not _asibla 0 37.5 75 i50 Feet Date 09.1-2022 Map: AD02D --\\ WY .0 City of Sunny Isles Beach Beach Corridor - St. Regis Residences (vacant) Marenas Beach, Millennium, Porsche Design, Turnberry Ocean Club, & Days Hotel Legend City Limits - Conatruelion ConbolLira Erosion Control Line Dune Classification No Dune i Dune nada o be rastorad or r-_oonigured Dune that is functional or non-functional on cityproperty Funotionaldunewithminimal exotioinistalon -�� Chroniooraporadioerosionordunainsmilstron nottssibN 0 37.5 75 150 iiiiM�iFeet Date: 09.1-2022 r•,lap: AD029 to-' +:• Z City of Sunny Isles Beach Beach Conidor- Sahara Beach Club, Dezer Property, Trump Royale, Trump Palace, & Trump International Legend City Limits - Con;truodon Convol Line Erosion Control Line Dune Classtrtcation No Duns Dune needs to be restored or recon igured ..

Overall, a 2:1 (beach to dune) ratio is recommended for the functionality of dune protection and habitat services. Properties with NO Dunes Management Recommendations • Plant sea oats and or other pioneer zone species in designated area. • Plant species should be selected from the Recommended Palette provided. • The planting area should be a minimum of 20 feet from the exiting seawall. • Dunes should be planted at grade. • Prune or limb -up tree species as necessary to provide window -pane views. • All access points should be at a 45* angle towards the ocean. • Access points should be a minimum of 6 feet wide. • Given an average width of the beach and the dune system of 120 feet, at 2:1 ratio (beach: dune) is recommended, with a dune width of 40 feet (to be reduced as required), providing a recreational beach width of +/- 80 feet, which allows for utilization by a variety of plants. • Planting areas larger than 100 square feet should utilize a minimum of three plant species. • Planting areas larger than 1000 square feet should utilize a minimum of eight plants species. • No more than 20% of each species will populate dune planting areas (with the exception of sea oats). • Where the dune is wide enough and where property owners allow, Pioneer Zones, Strand Zones and Coastal Hammock Zones should be planted by utilizing species from the Recommended Palette and placement in appropriate zone. • Seaward edge planting should be largely in line with existing stable vegetation. • Large scale projects that require heavy machinery should be conducted outside of marine turtle nesting season. • Annual inspection events should be conducted thereafter with maintenance activities provided on an as -needed basis. Properties with Dunes that need to be Restored or Reconfigured Management Recommendations • Remove non-native plant species. Large barren areas after removal should be replanted with species selected from the Recommended Palette provided to prevent erosion or recolonization by non-native plant species • Plant sea oats or other pioneer zone species in areas not yet colonized by dune species to reduce patchiness • Prune or limb -up tree species as necessary to provide window -pane views • Modify or retrofit access points to a 451 angle. • Large scale maintenance events should be conducted between November 1st and March 1st (outside of marine turtle nesting season), as heavy equipment will likely be required. It is preferred that the activities be conducted in February, close to the beginning of Florida's wet season. • Annual inspection events should be conducted thereafter with maintenance activities provided on an as -needed basis. Properties with a Functioning Dune with Minimal Exotic Infestation Management Recommendations • Non-native species should be identified and removed. • Infill any barren areas with species selected from the Recommended Palette provided. • Prune or limb -up tree species as necessary to provide window -pane views. • Modify or retrofit access points to a 45* angle if needed. • In areas where the vegetation has overgrown the existing beach access points, trim back the vegetation to provide approximately 6 feet of clearance. • Annual inspection events should be conducted thereafter with maintenance activities provided on an as -needed basis. City Properties With or Without Functioning Dune Management Recommendations • Remove non-native plant species. Large barren areas after removal should be replanted with species selected from the Recommended Palette provided to prevent erosion or recolonization by non-native plant species. • Plant sea oats or other pioneer zone species in areas not yet colonized by dune species to reduce patchiness. • Prune or limb -up tree species as necessary to provide window -pane views. • Modify or retrofit access points to a 45* angle. • In areas where the vegetation has overgrown the existing beach access points, trim back the vegetation to provide approximately 6 feet of clearance. • Large scale maintenance events should be conducted between April 1st to October 31st (outside of marine turtle nesting season). • Annual inspection events should be conducted thereafter with maintenance activities provided on an as -needed basis. • If possible, create a coastal hammock, strand and pioneer zones. Properties where Chronic or Sporadic Erosion or Dune Installation is NOT Feasible Management Recommendations Reevaluate status after future renourishment Recommended Dune Vegetation and Planting Guidelines Dune vegetation should be selected based on appropriateness for the proposed location, both within the State of Florida and within the cross-section of the dune. The Recommended Plant Palette for each cross-section of the dune system includes species native to the region which are salt -tolerant, drought tolerant, and are naturally found in coastal dune habitats. Please note that the recommended species do not preclude other native salt tolerant species from being proposed or allowed to grow within the dune. For instance, sea purslane (Halimoine portlacoides) may seed itself in a functional dune despite being unavailable from nurseries. For privately maintained dunes, a planting plan should be submitted for review/approval by City staff and FDEP under the Coastal Construction Control Line permitting program. The City's beaches and dune systems currently contain coconut palms, a Category II invasive species. They should be permitted to remain in the existing dunes. If a Coconut Palm is diseased or damaged or otherwise removed, it should be replaced with native palm such as a Sabal Palm or similar. All other Category I and II invasive plant species, as classified by the Florida Exotic Pest Plant Council, are not permitted within the dune system and should be removed. Plant Palette City of Sunny Isles Beach Plant Palette Irrigation Irrigation should be included only for those areas where new vegetation is proposed. Existing, established dunes should not be irrigated. If they have existing irrigation systems, it is recommended that they be removed. Irrigation should be provided until new vegetation is established, which is typically 60-90 days. Irrigation frequency is recommended daily for the first 2 weeks, every other day for the following 2 months, then weekly until established. Irrigation can be provided by the following two methods: • Temporary Irrigation System: An on -grade temporary irrigation system may be proposed for large areas of dune planting. As noted, a temporary irrigation system is located on grade, typically of a low-cost PVC pipe system, which can be removed once vegetation growth is established; or • Manual Irrigation: For discrete areas of planting, manual irrigation utilizing a water truck is recommended. Non -Native Species Non-native, or invasive/exotic plant species have an adverse effect on native plant communities, including loss of native plants due to non-native plant infestations and alteration of endangered species habitat. Non-native plant species can destabilize a dune community, resulting in reduced storm resilience. Non-native species should be removed and disposed of off-site when observed in the dunes. No on-site shredding or chipping will be allowed. Mechanized equipment may be used for removal when it is possible to gain access without impacting the existing dune. Post and rope barriers may be temporarily removed for mechanical invasive removal, but the post and rope must be replaced upon completion of each section. Non-native species observed in Sunny Iles Beach dunes include: • Scaevola taccadal (Hawaiian half -flower or beach naupaka) • Sphagneticola trilobata (wedelia or creeping oxeye daisy) • Crotalaria pallida (Shake shake) Other non-native species commonly found within South Florida's dune system include: • Casuarina equisetifolia (Australian pine) • Schinus terebinthifolius (Brazilian pepper) All invasive removal should be done manually either by hand or by machine. The use of herbicides is not recommended. .s_ �'\_ \ � (\ '� ' � +�� I [ ; t / 1` f'I��r� ` t •�, NSM ,'3 .I.,.' t . �1 Al �•'. l� �� .V 1 7F � . � V � � 1j f � ' I � �i�{5�--'j>✓ t; if r, f /'.� \\•�( �\r it rl� , � i I ,• 1, _� i Ati. r, r v � ;� '` —' � � � � �,, � � � t A ... � [ f r /s�4 a ..v.

Removal should include the root system to avoid regrowth; • Remove trash and man-made debris from dune areas; and • A Post -Storm Action Plan (assessment/maintenance to remove broken or dead tree limbs, removal of storm debris, repair damage to rope and post border, etc.). Timing Large scale projects that will require heavy equipment should be conducted between April 1st to October 31st, outside of marine turtle nesting season and prior to hurricane season. It is recommended that projects be implemented close to March 1st to take advantage of South Florida's wet season, which will help establish the plants, thus reducing watering needs. Semi-annual inspection events of all dune areas should be conducted thereafter with maintenance activities provided on an as -needed basis. It is recommended that the results of the initial (3-4) inspection events be tracked closely, and inspection frequency re-evaluated based on those results. Inspection of the dunes should also be conducted immediately after a storm event to address any repair or restoration as needed Dune & Beach Profile • A dune crest width of —10 feet • A dune crest maximum height of +11.0 feet NAVD • Dune side slope of 2:1 • A beach slope of 20:1 Beach Access Both public and private beach access points exist throughout the City's beach and dune system. The conditions of the access points vary greatly, depending on the location and current state of the adjacent dune. These access points may range from narrow, overgrown vegetated corridors to wide sand expanses, which cause windblown or over -washed sand to be deposited onto the landward sidewalk. Guidelines for Beach Access: • Unnecessary footpaths should be closed with vegetation planting to minimize the potential for storm -related breaches of the protective dune feature; • All new access points should be installed at an angle in order to prevent windblown sand and dune breaches. These access points should be installed at an oblique angle from southeast to northwest or northeast to southeast, depending on prevailing wind conditions; • Existing beach access paths should be augmented with an independent vegetation buffer at the seaward endpoint; • Public access point widths should be maintained at 6 feet; • Emergency vehicular access points, as designated by the City, should be maintained at a minimum of 10 ft width; and • Access points narrowed by overgrowth should be cut back and trees limbed up when possible. Impacts of Wildlife In South Florida, many threatened, endangered, and endemic species depend on a healthy beach and dune system. The Southeast Beach Mouse (Peromyscus polionotus niveiventris), the Piping Plover (Charadrium melodus), the Least Tern (Sternula antillarum), the Rim Rock Crowned Snake (Tantilla oolitica), Loggerhead Turtle (Caretta caretta), Green Sea Turtle (Chelonia mydas mydas), and Leatherback Turtle (Dermochelys coriacea) are examples of State and/or. Federally listed threatened or endangered animal species which depend on our beach and/or dune habitat. Likewise, Sea Lavender (Tournefortia gnapholodes), one of the plants listed in the Recommended Palette, is an endangered plant species native to the dunes. In addition to those threatened or endangered species, many other species depend on the beach environment, especially the Strand and Coastal Hammock Zones for food, cover, nectar, and/or larval resources. Many species in the Recommended Palette provide significant food and cover resources for wildlife including: Saw Palmettos, Cocoplum, Cabbage Palm, White Stopper, Marlberry, Blolly, Wild Coffee, & White Indigo Berry. Other species in the Recommended Palette provide moderate amounts of food and cover resources for wildlife including: Sea Grape & Gumbo Limbo. Many of the species in the Recommended Palette are either larval or nectar sources for moths and butterflies including: Saw Palmettos, Sea Lavender, Sea Grape, Cabbage Palm, White Stopper, Wild Coffee, White Indigo Berry, and Buttonwood. Those moths and butterflies, which could be brought to Sunny Isles Beach's dunes by following this Plan, are pictured in Figure 10. By selecting native plants which also provide habitat value, critical habitat which had largely been destroyed and/or displaced by development can be reestablished. Implementation Plan & Budget Phase 1: Pilot Project City Owned Property and Private Landowners with Matching Funds To restore and maintain Sunny Isles Beach's dune system, coordination will be needed with all private property owners. Those dunes which the City owns and maintains, Samson Beachfront Park and Pier Park, will be prioritized to complete restoration first, including the installation of a Strand Zone and Coastal Hammock Zone. Upon completion of this Plan's dune restoration efforts, regular operations and maintenance should be followed accordingly in order to prevent future large scale restoration efforts from disrupting native habitat and natural infrastructure.

The FDEP may issue Field Permits for the construction of limited minor structures (such as a wood gazebo), improvements, or activities, including the placement of beach -compatible sand fill up to 200 cubic yards; • Activities that are not exempt from FDEP CCCL permitting criteria and do not qualify for authorization under a Field Permit are required to obtain a formal FDEP administrative permit. One form of CCCL permit is the Area Wide Permit. This may be granted to local municipalities for special classes of activities in areas under their general jurisdiction or responsibility, provided that these activities do not cause a measurable interference with the natural functioning of the beach - dune system or with marine turtle nesting sites. Such activities include dune restoration and access for enhancing accessibility. An FDEP Area Wide Permit can be sought for beach planting and removal, and potentially other dune maintenance activities.

Changing conditions such as level rise, may require future adaptation scenarios. Based on the current predictions of sea level rise, the Dune Master Plan should be evaluated every 5 years to assure it provides the maximum protection from storm surge and beach erosion. MEMORANDUM TO: Honorable Mayor and City Commissioners FROM: Environment Sustainability Advisory Committee DATE: August 17, 2023 RE: Adoption of the Dune Master Plan RECOMMENDATION: The Environment Sustainability Advisory Committee ("ESAC" or "Committee") recommends adoptioi of this Resolution. REASONS: On January 20, 2022, via Ordinance 2022-576, the City created the ESAC for the purpose of providing guidance and advice regarding the City's efforts to provide and promote general environmental improvement trends, such as "green initiatives" and "sustainable development". Pursuant to the ESAC's powers and duties, the Committee made an advisory recommendation that the City develop and adopt a Dune Master Plan ("DMP"). Dunes are an important part of the City' coastal ecosystems that provides a habitat to a distinctive subset of regional biota, including the City's sea turtles. They also provide storm protection by maintaining and supplying sand to the City's beaches, protecting inland coastal areas from storm damage and flooding by coastal waves and elevated sea levels through the elevation and stored sand volume.
