In 2015, the Florida Legislature passed Senate Bill 1094, titled “Peril of Flood”. The new law, which became effective July 1, 2015, specifies new requirements for the coastal management element of a local government’s comprehensive plan related to coastal flooding and the related impacts of sea level rise.

See the text of the law here.

Regional Peril of Flood Initiatives

To comply with the Peril of Flood requirements, local governments must address development and redevelopment strategies to reduce flood risk.

Presently, the Tampa Bay area has experienced what an acute amount of rainfall can do in terms of damage. For instance, in 2015 the area experienced 7-9 inches of rain. Hurricane Harvey also set a precedent by showing that a storm could stall and double or triple rainfall totals for an area. The likelihood of a repeat event is not that far on the horizon. Since 1946 the Tampa Bay Area has seen a mean sea level rise increase of 7.8 inches.

In 2018, the TBRPC received a grant from the Florida Resilient Coastlines Program in the Florida Coastal Office of DEP with funding from NOAA’s Florida Coastal Management Program. The TBRPC organized meetings with Community Redevelopment Agencies (CRAs) for Hillsborough County and Pinellas County to discuss resiliency for business districts and affordable housing.

A one-day workshop “Conducting Social Vulnerability Assessments” reviewed demographic factors that increase resilience vulnerability and reviewed the CDC Social Vunlerability Index tool and ESRI Community Analyst databases. Planning and housing experts from USF, UF and Manatee County presented new data and assessments of market risks and flood risks to affordable housing, and identified strategies for mapping specific aspects of community vulnerability.

Peril of Flood Products and Resources

Manatee County Climate Portal, Housing Stock Analysis and Housing Map

For the POF project, Manatee County Government GIS Analyst Lea Harper developed the Manatee Climate Portal with Sea Level Rise inundation as well as infrastructure maps. Manatee County Redevelopment Coordinator Jeffrey Ryan developed analysis of housing stock and social impacts. The new tools were presented at the Manatee County workshop in April and the TBRPC workshop in June [Download Presentation].

Mapping CRAs’ flooding and Inundation risks

The TBRPC staff mapped the location of CRAs in Hillsborough, Pinellas and Pasco counties, using modelling and data developed for the Federal Highway Administration Grant (2018-2020). The maps visualize the inundation under an integrated threat scenario. The project looked at storm surge from a Category 3 hurricane and NOAA High sea level rise projections for 2045. Additional data was developed for the Pinellas County meeting to show the current and future projected percent of wet acres in 2045.

Mapping Mobile Home Parks

Mobile homes are extremely vulnerable to winds and storm surge. TBRPC member elected officials met in April for a Round Table Discussion Hurricanes and impacts to affordable housing. TBRPC staff mapped the mobile park density in Citrus, Hernando, Hillsborough, Manatee, Pasco and Pinellas counties. The maps supported better discussion of hurricane risks, social impacts to families and land use planning and development issues.

Analysis of Affordable Housing Risks and Impacts

Bill O’Dell, Director of UF’s Shimberg Center for Housing Studies conducted an analysis of climate threats and vulnerability of affordable housing stock and prepared an extensive presentation for the workshop [Download Presentation].

Workshop: Conducting Community Vulnerability Assessments

The TBRPC held a Peril of Flood workshop on June 14, 2019 which focused on assessing community social vulnerability factors and housing stock risks and integrating into resilience assessments. The presenters included university faculty and local government staff that have conducted community vulnerability assessments for Peril of Flood projects. The workshop provided new information on social vulnerability, housing stock issues, discussed situation-specific assessment rationale and strategies, and reviewed GIS tools, maps and new visualization products.

Workshop #2 Updating Your Coastal Management Element — Nature-Based Tools for Flood Protection

Nature-based strategies can reduce flood risks to private and public property, support ecological systems, and identify additional opportunities for open space and recreation lands to address the anticipated changes in climate and sea-level rise over time.

On March 21, 2019, the TBBRP, in collaboration with grant partners Manatee County and the University of Florida Resilience Communities Initiative, held a workshop to support local governments. The workshop introduced key principles, requirements and strategies to successfully develop and/or update their Comprehensive Plan Coastal Elements.

Workshop Objectives:

  1. Understand how statutory Peril of Flood provisions relate to community planning for coastal areas;
  2. Understand how nature-based strategies can augment or replace conventional engineering approaches to surge mitigation and stormwater management;
  3. Develop a list of priority projects that consider climate change impacts (extreme weather, storm surge, sea level rise);
  4. Evaluate community risk reduction benefits and other ecosystem services benefits for specific projects;
  5. Identify local sites that are suitable for nature-based adaptation projects;
  6. Identify barriers in local government plans, policies and processes that need to be updated;
  7. Select different tools for different project phases or types.

March 21st- Tools for Nature-Based Protection Measures that Work

APA CMs were provided:

TBRPC conducted a series of four (4) workshops in 2017 to convene local government planners, building officials, and floodplain managers, along with stakeholders from other government agencies and the private sector. Workshop participants:

  • Discussed the requirements of the Peril of Flood legislation for local government comprehensive plans
  • Identified best practices to address coastal flooding and the related impacts of sea level rise
  • Participated in knowledge sharing about strategies, principles, site development techniques, and related engineering solutions that will inform the goals, objectives, and policies to be developed by the local government for its coastal management element

Peril of Flood Florida Statute SB 1094


“Each must contain a coastal redevelopment component that addresses how to eliminate inappropriate and unsafe development in the coastal areas when opportunities arise redevelopment component must now:

  1. “Include development and redevelopment principles, strategies, and engineering solutions that reduce flood risk in coastal areas which results from high-tide events, storm surge, flash floods, stormwater runoff, and the related impacts of sea-level rise.
  2. “Encourage the use of best practices development and redevelopment principles, strategies, and engineering solutions that will result in the removal of coastal real property from flood zone designations established by the Federal Emergency Management Agency.
  3. “Identify site development techniques and best practices that may reduce losses due to flooding and claims made under flood insurance policies issued in this state.
  4. “Be consistent with, or more stringent than, the flood-resistant construction requirements in the Florida Building Code and applicable flood plain management regulations set forth in 44 C.F.R. part 60.
  5. “Require that any construction activities seaward of the coastal construction control lines established pursuant to s. 161.053 be consistent with chapter 161.
  6. “Encourage local governments to participate in the National Flood Insurance Program Community Rating System administered by the Federal Emergency Management Agency to achieve flood insurance premium discounts for their residents.”
