INTRODUCTION The purpose of the Coastal Management Element is to provide a plan for the protection of human life and coastal resources and to limit public expenditures in areas that are subject to natural disaster. II. DATA AND ANALYSIS REQUIREMENTS The coastal zone within the City of Dania Beach (see Natural Resources Map) is considered to be that area east of U.S.1 area consisting of approximately 1,300 acres. This includes the small portion of the City on the beach approximately two (2) miles from the main portion of the City. The high hazard area is located east of Southeast 5th Avenue and includes Dania Beach. A. Coastal Zone Inventory Table I identifies the existing land uses within the coastal zone utilizing the same land use hierarchy identified in the Land Use Data Section of the Land Use Element. As noted, the land uses occurring within the coastal zone provide for a mix of uses including various intensities of residential, commercial, industrial, park and recreational, and community facilities types. In addition, approximately 136 acres are vacant. Table II identifies the vacant land within the coastal high hazard zone by future land use type utilizing the same hierarchy identified in the Future Land Use Element. This inventory reflects approximately fifty (50) acres as industrial uses, employment center and transportation and would represent the area east of the Fort Lauderdale/Hollywood International Airport with approximately twenty-four (24) commercial and twelve (12) acres for residential uses. However, eight (8) acres of the residential is deed restricted for conservation. At the present time there are no conflicts with shoreline uses as the beach front is public and maintained as a recreational facility for the residents of the community. It is also utilized by residents of the Broward County area. The Florida Atlantic University's Sea Tech Oceanographic Institute is being developed on a component of the City of Dania Beach beach-front under a lease agreement with the City of Page 2 Coastal Management Element City of Dania Beach Dania Beach. This will provide a water related independent research facility for students and faculty studying oceanographic matters. There are other water related independent activities occurring with the Dania Cut-Off Canal, particularly marine industry orientated facilities. Because of the growing marine industry within the general Broward County area and the lack of facilities with ready access to the Intracoastal and Atlantic Ocean, Dania Beach finds itself as a desirable location for this type of development. The Natural Resources Map identifies the existing facilities within the town and also potential sites for expansion of these facilities. The economic base of the coastal portion of Dania Beach as reflected in existing land use provides for a diverse array of both residential and commercial activities. Industrial activities within Port Everglades plus commercial activities along Dania Beach Boulevard, including Dania Jai-Alai, provide employment opportunities and tax revenue for the community. The natural resources occurring within the coastal zone have been identified on the Coastal Resource Map. This map indicates generalized wetlands with vegetative cover and areas subject to coastal flooding and wildlife and marine habitats. As previously noted in other portions of the Comprehensive Plan there are mangrove communities occurring within portions of the eastern segment of the community. Many of these mangrove areas are stressed but all will require dredge and fill Permitting by the Florida Department of Environmental Regulations, Army Corps of Engineers and Broward County Department of Planning and Environmental Protection. The portions of the coastal zone which contain natural resources include generally the area east of 5th Avenue and south of Dania Boulevard which is a mangrove habitat. This area has been acquired by Broward County as the Dania Salt Marsh. The proposed future land uses have no effect on coastal flooding within the area as that primarily is related to the beach front which is a public beach facility and will continue to be maintained as such by the City of Dania Beach. The historic resources have been identified on the coastal Page 3 Coastal Management Element City of Dania Beach resources map and there are no redevelopment efforts through this Land Use Plan which would have an impact on historic resources (there are no archeological sites) in the coastal area. The historic resources are on the western limits of the coastal zone boundary within the downtown urban core of the City of Dania Beach and no impacts to these facilities will occur. None of these resources are within the high hazard boundaries. The City of Dania Beach beach area is non-contiguous to the remainder of the City as indicated on the future land use maps. There is a relic dune system with sparse vegetative cover of sea oats and sea oxeye. Coastal flooding may occur in this area and is designated as high-hazard V-13 on the FEMA maps. B. Estuarine Conditions The Dania Beach area is essentially developed with recreational uses. Traffic circulation is not intended to change and the area is serviced by sanitary sewer and potable water. All stormwater drainage receives pre-treatment via swales and detention. The New River Sound which is located in the Dania Beach area and depicted on the Estuarine Map is located in an area which due to its proximity to the Port Everglades Inlet receives a substantial tidal flow and related flushing. Accordingly, the pollution within this area is very limited and the water quality which is designated as a Class III by the Florida Development of Environmental Protection is good. There are no point or non-point source pollution problems within the estuarine area. The eastern area of the estuary is bulkheaded and a part of a small boat marina docking facility. No development will be permitted within the estuary and accordingly no new pollution factors will be introduced. The regulatory programs which are in place to help protect this estuary are those of the Florida Department of Environmental Protection, the goals and policies and objectives of the South Florida Regional Planning Council Regional Policy Plan, the South Florida Water Management District’s criteria as it relates to stormwater runoff, and locally the Broward County Water Resources Management Division, the Broward County Department of Planning and Environmental Protection, and the City of Dania Beach maintain programs including stormwater runoff, wetlands protection among others which will maintain or Page 4 Coastal Management Element City of Dania Beach improve the estuarine and environmental quality. In addition, as noted earlier, the City of Dania Beach will not permit any additional development which will have a negative impact to the water quality of this estuary. The new marina facilities which are being expanded or added within the City of Dania Beach are sited approximately 1.5 miles west of this estuary and are situated along the Dania Cut-off Canal. In the permitting processes for these new facilities the City of Dania Beach requires stormwater management plans which will eliminate any non-point source pollution. Also, the Broward County Department of Planning and Environmental Protection regulates any storage tank requirements locally and the Florida Department of Protection has this responsibility on a regional level. Those agencies will require that all storage tank construction be in accordance with their standards and monitored in accordance with their regulations thereby eliminating any threat of contamination from these facilities. The beach area of the City of Dania Beach has existing infrastructure in place which will suffice for both existing and proposed land uses. The area is accessed by Dania Beach Boulevard (four lane divided) from the west and A1A (two lanes) from the south, both of which are part of the State primary road system, The intracoastal waterway is spanned by a four lane bascule type bridge. Both of these facilities operate at level of service D and are functioning adequately. Sanitary sewer and potable water systems are in place and are adequate to meet any existing or future demands. Drainage in this area is provided by natural percolation and there are no man-made drainage facilities. The existing percolation areas will service both the existing and future needs of the area. The area of the City east of U.S. 1 is essentially developed. The major east-west traffic facility is Dania Beach Boulevard which is six lane divided. The major north-south facility is S.E. Fifth Avenue which is two lane with intersection improvements. Both facilities are adequate to address build-out conditions. Sanitary sewer and potable water in the area is adequate for existing needs. The sanitary sewer is adequate for future build out and the potable water has recently been up to handle build out flows. The area north of the Dania Cut-Off Canal and east of U.S.1 is substantially developed. The area north of Northeast 10th Street Page 5 Coastal Management Element City of Dania Beach has been acquired by Broward County for an airport runway and de-annexed from the City. Water and sewer have been provided to the area that will adequately handle the intended future land uses. Drainage will be provided by on-site percolation as development occurs.

Like the lost treasures, these amazing reefs lie just a few hundred yards off the shores of Martin, Palm Beach, Broward and Miami-Dade Counties where more than one-third of Florida’s 19 million residents live. Fishing, diving, and boating help attract millions of visitors to southeast Florida each year (30 million in 2008/2009). Reef-related expen- ditures generate $5.7 billion annually in income and sales, and support more than 61,000 local jobs. Such immense recreational activity, coupled with the pressures of coastal development, inland agriculture, and robust cruise and commercial shipping industries, threaten the very survival of our reefs. With your help, reefs will be protected from local stresses and future generations will be able to enjoy their beauty and economic benefits. Coral reefs are highly diverse and productive, yet surprisingly fragile, ecosystems. They are built by living creatures that require clean, clear seawater to settle, mature and reproduce. Reefs provide safe havens for spectacular forms of marine life. Unfortunately, reefs are vulnerable to impacts on scales ranging from local and regional to global. Global threats to reefs have increased along with expanding ART SEITZ human populations and industrialization. Now, warming seawater temperatures and changing ocean chemistry from carbon dioxide emitted by the burning of fossil fuels and deforestation are also starting to imperil corals.

  • CITY of MIAMI BEACH DUNE MANAGEMENT PLAN January 2016
    CITY OF MIAMI BEACH DUNE MANAGEMENT PLAN January 2016 Prepared by: CITY OF MIAMI BEACH COASTAL MANAGEMENT 1700 Convention Center Drive AND CONSULTING Miami Beach, Florida 33139 7611 Lawrence Road Boynton Beach, Florida 33436 I. STATEMENT OF PURPOSE Coastal dunes are habitat for wildlife and support a high biodiversity of flora and fauna. They also keep beaches healthy by accreting sand and minimizing beach erosion rates. The dunes protect coastal infrastructure and upland properties from storm damage by blocking storm surge and absorbing wave energy. Therefore, a healthy dune system is an invaluable asset to coastal communities like Miami Beach. The purpose of the City of Miami Beach Dune Management Plan (“the Plan”) is to outline the framework and specifications that the City will use to foster and maintain a healthy, stable, and natural dune system that is appropriate for its location and reduces public safety and maintenance concerns. The Plan shall guide the City’s efforts in managing the urban, man-made dune as close to a natural system as possible and ensuring the dune provides storm protection, erosion control, and a biologically-rich habitat for local species. II. OBJECTIVES This plan was developed collaboratively with local government and community stakeholders, as well as local experts to meet the following primary objectives: 1. Reduce to the maximum extent possible the presence of invasive, non-native pest plant species within the dune system. Non-native species compete with and overwhelm more stable native dune plants, thereby threatening the stability and biodiversity of the dune system. Reducing the presence of aggressive, non-native vegetation preserves and promotes the structural integrity and biodiversity of the dune.

S017 1BJ. 8 9 * Sally Brown ([email protected], Telephone: +44(0)2380 594796). 10 11 Abstract: Building defences, such as groynes, on eroding soft cliff coastlines alters the 12 sediment budget, changing the shoreline configuration adjacent to defences. On the 13 down-drift side, the coastline is set-back. This is often believed to be caused by increased 14 erosion via the ‘terminal groyne effect’, resulting in rapid land loss. This paper examines 15 whether the terminal groyne effect always occurs down-drift post defence construction 16 (i.e. whether or not the retreat rate increases down-drift) through case study analysis. 17 18 Nine cases were analysed at Holderness and Christchurch Bay, England. Seven out of 19 nine sites experienced an increase in down-drift retreat rates. For the two remaining sites, 20 retreat rates remained constant after construction, probably as a sediment deficit already 21 existed prior to construction or as sediment movement was restricted further down-drift. 22 For these two sites, a set-back still evolved, leading to the erroneous perception that a 23 terminal groyne effect had developed. Additionally, seven of the nine sites developed a 24 set back up-drift of the initial groyne, leading to the defended sections of coast acting as 1 25 a hard headland, inhabiting long-shore drift.

  • Dynamics of Beach Sand Made Easy
    Dynamics of Beaches Made Easy Page 1 Dynamics Of Beaches Made Easy San Diego County Chapter of the Surfrider Foundation 1. Introduction Beaches are made up of more than just sand. In California beaches are generally formed by erosion of uplifted plates resulting in cliff backed beaches or in the delta areas of rivers or watersheds. Beach sand is an important element of beaches but not the only element. Wavecut platforms or tidal terraces are equally important in many areas of San Diego. The movement of beach sand is governed by many complex processes and variables. However, there are a few very basic elements that tend to control not only how much sand ends up on our beaches, but also how much sand exists near enough to the shore to be deposited on the beach under favorable conditions. The following is a brief description of the most important issues influencing the current condition of our local beaches with respect to sand. Dynamics of Beaches Made Easy Page 2 2. Geology The geology of San Diego County varies from sea cliffs to sandy beaches. Beaches are generally found at the mouths of lagoons or in the lagoon or river outfalls. Cliffs formed by tectonic activity and the erosion via marine forces deserve special mention. Much of San Diego’s coastline consists of a wavecut platform sometimes referred to as a tidal terrace. A wavecut platform is formed where a seacliff is eroded by marine action, meaning waves, resulting in the deposition of cliff material and formation of a bedrock area where erosion occurred.

The Florida Legislature has declared that the Department of Environmental Protection constitutes the beach and shore preservation authority for the state and has directed the Department to develop and maintain a comprehensive long-term management plan for the restoration and maintenance of the state’s critically eroded beaches fronting the Atlantic Ocean, Gulf of Mexico and the Straits of Florida. The Department has developed the SBMP, incorporating by reference adopted Inlet Management Implementation Plans (IMP’s), and held public meetings for the which the SBMP has been prepared, in accordance with Sections 161.091, 161.101, and 161.161, Florida Statutes. The Department initially adopted the SBMP in October 2000, and has subsequently updated the SBMP in May 2008, to reflect current conditions and management strategies. Public meetings were held on December 9th, 10th and 11th of 2014 for the updated SBMP, dated June 2015. Comments were received from the public during the meetings and also by way of e-mails after the public meetings. The public comments were reviewed and edits were made to the SBMP by the Department that were deemed necessary.
