VALUE OF FLORIDAS BEACHES

• First line of defense against storms
  
• Economic (2003 FAU Report)
• Protect more than 150 billion in taxable
  property
• 37.9 billion from tourism
• 800,000 jobs and
• over 500 million in sales and use tax revenues
• Environmental - provide habitat for threatened
  and endangered flora and fauna
• Recreation

5
Beach/Dune System
A VALUABLE RESOURCE

• Sand Source Protective Barrier
• Public Recreation Tourist Revenue
• Wildlife Habitat

6
VALUE OF FLORIDAS BEACHES
The Legislature finds and declares that the
beaches in this state and the coastal barrier
dunes adjacent to such beaches, by their nature,
are subject to frequent and severe fluctuations
and represent one of the most valuable natural
resources of Florida and that it is in the public
interest to preserve and protect them from
imprudent construction which can jeopardize the
stability of the beach-dune system, accelerate
erosion, provide inadequate protection to upland
structures, endanger adjacent properties, or
interfere with public beach access.

Regulatory History

• 1970 Fifty-foot Setback from MHWL
• 1971 Coastal Construction Setback Line
• 1981 Legislation to Reestablish CCCL
• 1985 30 Year Erosion Projection
• 2002 Florida Building Code

• 1978 Coastal Construction Control Line
  (Replaces Setback Line)

8
Coastal Construction Control Line Program (CCCL)

• 161.053(1)(a).coastal construction control
  linessandy beaches fronting the Atlantic, Gulf
  of Mexico or Straits of Florida... to be
  established to define that portion of the
  beach-dune system subject to severe fluctuations
  based on a 100 year storm surge, storm waves, or
  other predictable weather conditions

9
Coastal Construction Control Line Program
The purpose of regulation is to prevent imprudent
construction which can.

• provide inadequate protection to upland
  structures
• endanger adjacent properties
• accelerate erosion
• Interfere with lateral public beach access
• jeopardize the stability of the beach and dune
  system.

10
Dog Island, Franklin County Chronology

• 1981 Legislative mandate to reestablish any CCCL
  not updated since June 1980
• April 30, 1984 CCCL Adopted
• 2006 Restudy of CCCL Initiated
• August 2007 Hold Public Adoption Hearing
• December 2007 Planned Adoption of Reestablished
  CCCL

11
Governors Coastal High Hazard Study Committee

• As a direct result of the severe hurricane
  activity during the 2004 and 2005 seasons the
  Coastal High Hazard Study Committees report
  (dated February 1, 2006) recommended that the DEP
  restudy the CCCLs along identified portions of
  the Florida Panhandle and reestablish the line(s)
  as necessary in order to protect life, property,
  and the beach and dune system.
• A comprehensive engineering study was conducted
  in Franklin County resulting in a recommendation
  for the re-location of the CCCL for Dog Island.

12
Coastal Construction Control Line Reestablishment
Process

• CCCLs are established on a county by county
  basis
• The study process results in three reports
• Storm Surge Model Study
• CCCL Study
• A Statement of Estimated Regulatory Cost (SERC)
  of the proposed movement of the CCCL.

13
Critically Eroded

• Segment of shoreline
• Natural processes or human activity
• Threatened or lost
• Upland development, recreational interests,
  wildlife habitat, or important cultural resources

Coastal Construction Control Line Regulatory
Program
The Coastal Construction Control Line (CCCL) is a
line of jurisdiction and not a setback line

Coastal Construction Control Line

• What is it?
• Line of jurisdiction for CCCL regulatory program
• Defines portion of beach-dune system subject to
  severe fluctuations associated with a 100-yr.
  storm surge
• Only on sandy beaches
• Established by Rule (Chapter 62B-26, F.A.C.)

21
What Counties Have a CCCL?
22
Franklin County, Dog IslandCCCL Facts

• Since 1984, 42 CCCL administrative permits and 90
  plus field permits issued.
• The proposed relocation of the CCCL affects
  approximately 21 existing residences on Dog
  Island.

23
Rule 62B-33, F.A.C.

• Regulates construction seaward of the CCCL
  requires siting and other design considerations
  that provide for
• Protection of the beach and dune system
• Protection of structures
• Protection of adjacent property
• Preservation of public beach access
• Protection of nesting sea turtles, hatchlings,
  and their habitat

24
Regulatory Principles

• Maintain adequate setback from beach and dune
• Elevate buildings atop pile foundations

25
Florida Building Code

• Effective March 1, 2002, local building
  departments enforce the building design standards
  of the CCCL program.
• Building design standards for habitable
  structures sited seaward of the CCCL are
  contained in Chapter 31 (Special Construction),
  s. 3109 of the code.
• DEP enforces the environmental provisions of the
  CCCL Program, therefore, a DEP environmental
  permit is required for proposed activities
  seaward of the CCCL.

26
Types of CCCL Permits Issued

• Administrative Permits
• Field Permits
• General Permits
• Areawide Permits
• Emergency Permits

27
Administrative Permits
Examples single and multifamily dwellings,
swimming pools, coastal armoring, etc.
28
Siting and Design Considerations

• Provide adequate setback between development and
  dune system
• Site major structures landward of the 30 year
  erosion projection
• Limit excavation and minimize removal of dune
  stabilizing vegetation
• Construction should not cause impacts to adjacent
  properties
• Avoid Take of Marine Turtle Nesting Habitat
• Minor Impacts - Minimize
• Adverse Impacts - Minimize and Mitigate
• Rebuilding - Seek Net Improvement
• Significant Adverse Impacts - Deny Application

Application Procedure for Administrative Permits
Allows for..

• 62B-33.008 Permit Application Requirements
• 30 days for completeness review in which DEP may
  request additional information
• 90 days after completeness date to issue a final
  order

31
Field Permits
Issued by the local field inspector for minor
activities within their delegation.
Examples dune walkovers, decks, storage sheds,
privacy walls, driveways, etc.
Field Representative for Franklin County is Bill
Fokes. 1-877-314-1329 Permit Manager for
Franklin County is Valerie Jones 1-850-921-7849
32
Exemptions are granted for...

• Grandfathering - Existing structures or
  structures under construction at the time of the
  CCCL reestablishment.
• Improvements to existing structures which remain
  with the existing foundation limits and do not
  include foundation work.
• Examples Second floor addition
• Roof replacement

33
Challenges

• Protect and enhance the beach and dune system.
• Make buildings more resistant to flooding and
  coastal storms.
• Manage the development and redevelopment of land
  in hazardous areas.

Future Sea Level Rise and Erosion

• Global sea level rose at 2 mm/yr in 20th
  century, ...
• 50 increase in rise rate since WWII.
• global sea level rise and erosion rates could go
  up 3 or 4 times in the 21st century!
