Algae are aquatic, photosynthetic plant-like organisms and include calcareous macroalgae, fleshy macroalgae, turf algae, and crustose coralline algae. Anemones & zooanthids are cnidarians very similar to coral, but are not characteristic reef builders. Civil Engineering and Construction specializes in the design and construction of infrastructure, including buildings and homes, roads, utility lines, and ports. Coral is a colonial marine animal consisting of polyps. Cultural services are the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, recreational opportunities, aesthetic experiences, sense of place, and educational and research opportunities. Discharge limitations are responses to regulate and control the discharge of pollutants and the use of chemicals. Ecosystem monitoring and restoration refers to responses to directly alter the condition of the reef ecosystem through restoration or remediation activities, setting limits on degradation through biological criteria or water quality criteria, or improving knowledge through monitoring, mapping, and scientific research. Ecosystem services are the benefits people obtain from ecosystems . Fish are cold-blooded aquatic vertebrates that breathe through gills and usually have scales. An Invertebrate is any animal that lacks a backbone. Landscape Changes are alterations of the natural landscape through human activities, including coastal development, shoreline armoring, impervious surfaces, deforestation, or soil disturbance, which can alter water flow patterns and lead to pollutant runoff into coastal systems. Landuse management pertains to responses that determine the use of land for development and construction. Marine vertebrates are aquatic animals with a backbone, such as sea turtles, whales, dolphins and marine birds. Nutrients are essential elements needed by plants and animals for growth and primarily include nitrogen, phosphorous, and potassium, as well as minor nutrients such as calcium, magnesium, or zinc. The Reef Ecosystem includes a suite of abiotic variables that form the physical and chemical environment. Plankton are any plants or animals that are too small to actively move against ocean currents. Pressures are human activities that create stress on the environment. Provisioning services are the products or ecosystem goods obtained from ecosystems, including seafood, genetic and biochemical resources, pharmaceuticals, ornamental resources, and water resources. The state of the Reef Ecosystem is the condition, in terms of quantity and quality, of the abiotic and biotic components including physical, chemical, and biological variables. Reef Habitat is the abundance, distribution, and condition of the benthic components of the reef ecosystem. Reef Inhabitants are all of the motile components of the reef ecosystem, including fish, invertebrates, marine reptiles and mammals, and are quantified by their abundance, distribution, and condition. Reef Life is the abundance, distribution, and condition of the biological components of the coral reef ecosystem. Regulating Services are benefits obtained from ecosystem processes that regulate the environment, including erosion regulation, natural hazard regulation, and climate regulation. Responses are actions taken by groups or individuals in society and government to prevent, compensate, ameliorate or adapt to changes in Ecosystem Services or their perceived value. Sea temperature is a measure of the warmth of ocean waters, and depends on water depth, solar radiation, water circulation patterns, and atmospheric temperatures. Seawater flow reflects circulation patterns, currents, and wave action that move water throughout the ocean and towards the coastline. Sediment includes dirt, sand, silt, clay, and small rocks that form soil on land or soft substrate in marine habitats, and may be transported by water, wind, or human activities. Shoreline armoring is the construction of bulkheads, seawalls, riprap or any other structure used to harden a shoreline against erosion. Shoreline Protection is the attenuation of wave energy by reefs that protects coastal communities against shoreline erosion and flooding during storms, hurricanes, and tsunamis that can cause property damage and loss of life. Socio-Economic Drivers include the sectors that fulfill human needs for Food & Raw Materials, Water, Shelter, Health, Culture, and Security, and the Infrastructure that supports the sectors. Sponges are sessile colonial animals with soft porous bodies supported by a fibrous skeletal framework. Storms and hurricanes are periodic events of high precipitation, winds, wave action, and flooding that can potentially cause damage to reef habitat, property, or human lives. Supporting services are ecological processes that indirectly benefit humans by maintaining a functional ecosystem for the production of other ecosystem goods and services. Toxics are chemical pollutants that are poisonous, carcinogenic, or otherwise directly harmful to humans, plants, or animals. The Transportation Sector involves comprises all modes of transportation (Aviation, Maritime, Mass Transit, Highway, Freight Rail, and Pipeline) The Transportation Systems Sector is segmented into six key subsectors, or modes, which operate independently within both a regulated and non-regulated environment, yet are also highly interdependent. Tunicates, or Waterborne discharges include direct and indirect discharges of pollutants into the aquatic environment, including chemicals, nutrients, sediment, and pathogens. A wetland is an area of land whose soil is saturated with moisture either permanently or seasonally.

CMap Description

Human activities that alter the landscape, including shoreline armoring and impervious surfaces, can alter surface and groundwater flow, causing freshwater discharge into coastal waters, and altering patterns of seawater flow. Seawater flow and circulation patterns influence sea surface temperature levels and alter the concentration and distribution of contaminants. Seawater circulation also influences the transport and recruitment of passive larvae and mobile adults, and ultimately the connectivity among marine aquatic populations. Coral reefs and wetlands can also alter seawater flow through wave energy attenuation, providing calm waters that may enhance recruitment of larval fish and invertebrates, in additional to protecting coastal communities from flooding or erosion. Water flow patterns can be monitored and mapped to better understand connectivity among populations, or potential patterns of contaminant distribution. Landuse or hydrological management can be implemented to minimize alterations to water flow patterns. Many of the same socio-economic sectors, such as transportation, civil engineering, and construction that create pressures on the reef also benefit from reef goods and services, such as shoreline protection or recreational opportunities that contribute to the cultural identity of the local community.

Energy Policy & Development: Develop Offshore Wind and Hydrokinetic Alternative Energies Policies encouraging or authorizing construction of offshore facilities are evolving, and there are many sides to the issue of how to best manage them. Alternative energies are desirable and would reduce the dependence on fossil fuel resources. However, hydrokinetic technologies are just becoming viable, meaning long term impacts are still unknown. Facilitative policies reduce barriers for alternative energy development or increase barriers or costs for incumbent technologies. These include research and innovation policies, technology improvement subsidies, market based policies that internalize externalities, and regulatory changes that simplify the permitting process.

Waterway Management: Manage Canal Water Quality This management option addresses water quality issues that may arise from nearshore, confined areas, specifically dead-end canals. This management response does not focus on wastewater discharges into canals, but instead on the hydrologic structure and orientation of the canal itself. Physical problems with canal orientation can lead to such problems as low flushing and build-up of weed wrack. This is a problem because the build-up of weed wrack consumes oxygen and releases nutrients as it decays. When combined with low flushing and circulation, dead end canals have decreased oxygen concentrations, accelerated eutrophication, and accumulate organic materials, pollutants and sediment. To improve the current canal system, management can inventory and map canals to identify high risk hotspots and candidates for future canal restoration projects. Canals are typically constructed to best suit the water access needs of local homes and businesses. Preventing high risk canals from being constructed, or placing certain requirements on their construction through permitting is one way to reduce future problem spots. Some design strategies include: Construct non-linear canals without right-angles and flared inlets oriented to prevailing winds. Instead of dead-ends, canals should include a flow through water exchange system or install mechanical pumps. Canals should be as wide as possible in relation to depth and length. Canal depth should be uniform or progressively shallower away from the parent waterbody, with sloping banks (eliminate requirements for navigable depths to shoreline). Some canal improvement strategies include: Implement weed gates, air curtains, and aeration systems. Direct all stormwater and effluent away from canal systems. Reduce bulkheading and restore native vegetative buffers (#1). Promote diversity of substrates and habitats. NOAA Marine Sanctuary Program. 2007.

Rules and Procedures for Coastal Construction and Excavation, 62B-033 Florida Administrative Code (2008). (1) The beach and dune system is an integral part of the coastal system and represents one of the most valuable natural resources in Florida, providing protection to adjacent upland properties, recreational areas, and habitat for wildlife. A coastal construction control line (CCCL) is intended to define that portion of the beach and dune system which is subject to severe fluctuations caused by a 100-year storm surge, storm waves, or other forces such as wind, wave, or water level changes. These fluctuations are a necessary part of the natural functioning of the coastal system and are essential to post-storm recovery, long term stability, and the preservation of the beach and dune system. However, imprudent human activities can adversely interfere with these natural processes and alter the integrity and functioning of the beach and dune system. The control line and 50-foot setback call attention to the special hazards and impacts associated with the use of such property, but do not preclude all development or alteration of coastal property seaward of such lines. (2) In order to demonstrate that construction is eligible for a permit, the applicant shall provide the Department with sufficient information pertaining to the proposed project to show that adverse and other impacts associated with the construction have been minimized and that the construction will not result in a significant adverse impact. (3) After reviewing all information required pursuant to this rule chapter, the Department shall: (a) Deny any application for an activity which either individually or cumulatively would result in a significant adverse impact including potential cumulative effects. In assessing the cumulative effects of a proposed activity, the Department shall consider the short-term and long-term impacts and the direct and indirect impacts the activity would cause in combination with existing structures in the area and any other similar activities already permitted or for which a permit application is pending within the same fixed coastal cell. The impact assessment shall include the anticipated effects of the construction on the coastal system and marine turtles. Each application shall be evaluated on its own merits in making a permit decision; therefore, a decision by the Department to grant a permit shall not constitute a commitment to permit additional similar construction within the same fixed coastal cell. (b) Deny any application for an activity where the project has not met the Department�s siting and design criteria; has not minimized adverse and other impacts, including stormwater runoff; or has not provided mitigation of adverse impacts. (4) The Department shall issue a permit for construction which an applicant has shown to be clearly justified by demonstrating that all standards, guidelines, and other requirements set forth in the applicable provisions of Part I, Chapter 161, F.S., and this rule chapter are met, including the following: (a) The construction will not result in removal or destruction of native vegetation which will either destabilize a frontal, primary, or significant dune or cause a significant adverse impact to the beach and dune system due to increased erosion by wind or water; (b) The construction will not result in removal or disturbance of in situ sandy soils of the beach and dune system to such a degree that a significant adverse impact to the beach and dune system would result from either reducing the existing ability of the system to resist erosion during a storm or lowering existing levels of storm protection to upland properties and structures; (c) The construction will not direct discharges of water or other fluids in a seaward direction and in a manner that would result in significant adverse impacts. Forthe purposes of this rule section, construction shall be designed so as to minimize erosion induced surface water runoff within the beach and dune system and to prevent additional seaward or off-site discharges associated with a coastal storm event. (d) The construction will not result in the net excavation of the in situ sandy soils seaward of the control line or 50-foot setback; (e) The construction will not cause an increase in structure-induced scour of such magnitude during a storm that the structure-induced scour would result in a significant adverse impact; (f) The construction will minimize the potential for wind and waterborne missiles during a storm; (g) The activity will not interfere with public access, as defined in Section 161.021, F.S.; and (h) The construction will not cause a significant adverse impact to marine turtles, or the coastal system. (5) In order for a manmade frontal dune to be considered as a frontal dune defined under Section 161.053(6)(a)1., F.S., the manmade frontal dune shall be constructed to meet or exceed the protective value afforded by the natural frontal dune system in the immediate area of the subject shoreline. Prior to the issuance of a permit for a single-family dwelling meeting the criteria of Section 161.053(6)(c), F.S., the manmade frontal dune must be maintained for a minimum of 12 months and be demonstrated to be as stable and sustainable as the natural frontal dune system. (6) Sandy material excavated seaward of the control line or 50-foot setback shall be maintained on site seaward of the control line or 50-foot setback and be placed in the immediate area of construction unless otherwise specifically authorized by the Department. (7) Swimming pools, wading pools, waterfalls, spas, or similar type water structures are expendable structures and shall be sited so that their failure does not have adverse impact on the beach and dune system, any adjoining major structures, or any coastal protection structure. Pools sited within close proximity to a significant dune shall be elevated either partially or totally above the original grade to minimize excavation and shall not cause a net loss of material from the immediate area of the pool. All pools shall be designed to minimize any permanent excavation seaward of the CCCL. (8) Major structures shall be located a sufficient distance landward of the beach and frontal dune to permit natural shoreline fluctuations, to preserve and protect beach and dune system stability, and to allow natural recovery to occur following storm-induced erosion. Where a rigid coastal structure exists, proposed major structures shall be located a sufficient distance landward of the rigid coastal structure to allow for future maintenance or repair of the rigid coastal structure. Although fishing piers shall be exempt from this provision, their foundation piles shall be located so as to allow for the maintenance and repair of any rigid coastal structure that is located in close proximity to the pier.(9) If in the immediate area a number of existing major structures have established a reasonably continuous and uniform construction line and if the existing structures have not been unduly affected by erosion, except where not allowed by the requirements of Section 161.053(6), F.S., and this rule chapter, the Department shall issue a permit for the construction of a similar structure up to that line. (10) In considering applications for single-family dwellings proposed to be located seaward of the 30-year erosion projection pursuant to Section 161.053(6), F.S., the Department shall require structures to meet criteria in Section 161.053(6)(c), F.S., and all other siting and design criteria established in this rule chapter. (11) In considering project impacts to native salt-tolerant vegetation, the Department shall evaluate the type and extent of native salt-tolerant vegetation, the degree and extent of disturbance by invasive nuisance species and mechanical and other activities, the protective value to adjacent structures and natural plant communities, the protective value to the beach and dune system, and the impacts to marine turtle nesting and hatchlings. The Department shall restrict activities that lower the protective value of natural and intact beach and dune, coastal strand, and maritime hammock plant communities. Activities that result in the removal of protective root systems or reduce the vegetation�s sand trapping and stabilizing properties of salt tolerant vegetation are considered to lower its protective value. Construction shall be located, where practicable, in previously disturbed areas or areas with non-native vegetation in lieu of areas of native plant communities when the placement does not increase adverse impact to the beach and dune system. Planting of invasive nuisance plants, such as those listed in the Florida Exotic Pest Plant Council�s 2005 List of Invasive Species � Categories I and II, will not be authorized if the planting will result in removal or destruction of existing dune-stabilizing native vegetation or if the planting is to occur on or seaward of the dune system. A copy of this list is available on the Internet at www.fleppc.org; or can be obtained by writing to the Department of Environmental Protection, Bureau of Beaches and Coastal Systems, 3900 Commonwealth Boulevard, Mail Station 300, Tallahassee, Florida 32399-3000; or by telephoning (850) 488-7708. Special conditions relative to the nature, timing, and sequence of construction and the remediation of construction impacts shall be placed on permitted activities when necessary to protect native salt-tolerant vegetation and native plant communities. A construction fence, a designated location for construction access or storage of equipment and materials, and a restoration plan shall be required if necessary for protection of existing native salt-tolerant vegetation during construction. (12) Special conditions relative to the nature, timing, and sequence of construction shall be placed on permitted activities when necessary to protect marine turtles and their nests and nesting habitat. In marine turtle nesting areas, all forms of lighting shall be shielded or otherwise designed so as not to disturb marine turtles. Tinted glass or similar light control measures shall be used for windows and doors which are visible from the nesting areas of the beach. The Department shall suspend any permitted construction when the permittee has not provided the required protection for marine turtles and their nests and nesting habitat.

Application to Coral Reefs:Regulation of coastal construction through permit review and modification will protect coastal ecosystems from degradation and loss and in doing so protects other marine ecosystems including coral reefs.

Legislative Actions:Chapter 62B-33 Florida Administrative Code, provides the design and siting requirements that must be met to obtain a coastal construction control line permit.Approval or denial of a permit application is based upon a review of the potential impacts to the beach dune system, adjacentproperties, native salt resistant vegetation, and marine turtles.

Comments:The Coastal Construction Control Line (CCCL) is an essential element of Florida's coastal management program. It provides protection for Florida's beaches and dunes while assuring reasonable use of private property. Recognizing the value of the state's beaches, the Florida legislature initiated the Coastal Construction Contorl Line Program to protect the coastal system from improperly sited and designed structures which can destabilize or destroy the beach and dune system. Once destabilized, the valuable natural resources are lost, as are its important values for recreation, upland property protection and environmental habitat. Adoption of a coastal construction line establishes an area of jurisdiction in which special siting and design criteria are applied for construction and related activities.These standards may be more stringent than those already applied in the rest of the coastal building zone because of the greater forces expected to occur in the more seaward zone of the beach during a storm event.
