DRAFT Special Occupancy TAC Proposed Research Project
“Research on Code Considerations for Public Restrooms Below BFE”
Background
Florida has 100 million annual tourists and over 30
million residents most of which participate in some form of outdoor recreation
activities at beaches, estuaries and lakes and rivers. Obviously, use of restrooms is a human need as
common as consuming food, obtaining protection from elements, and obtaining
rest in a safe and protected space. Yet, neither the Florida Building Codes nor
International Building Codes include a definition, or establish construction
standards, for public restrooms or recognize the unique, single-use purpose of
public restrooms in places where the public congregates to enjoy nature, participate
in recreational activities, or to relax in natural areas. Since Congress created the National Flood
Insurance Program in 1968, program administrators developed regulations
designed to minimize loss to structures by requiring that they be elevated
above a base flood elevation (BFE). And, not until 1990 did Congress adopt the
Americans with Disabilities Act which requires universal accessibility to
public and private facilities including public restrooms.
Florida communities struggle to meet the public need for
public restrooms, and all communities face challenges for constructing facilities
that comply with federal-imposed requirements for elevated, flood resistant and
accessible buildings as is required by Florida Building Code. Communities must
design and provide facilities that are flood resilient under the NFIP
requirements and simultaneously meet the ADA requirements. The obvious solution
is to determine whether it is feasible to design and construct public restroom
structures below BFE that may withstand the combination flood and wind loads associated
with the NFIP’s 1% annual base flood and that are more accessible as required
by the ADA.
Research Need and/or Technical Enrichment
For nearly 50 years, the NFIP considers public restrooms
as non-residential structures that must be constructed above the base flood
elevation in special flood hazard areas (SFHAs), including coastal high hazard
areas (Zone V). However, in Zones A,
they may be constructed below the BFE if dry flood-proofed. By their nature, public restrooms are typically
built with flood-damage resistant materials; ironically, the NFIP prohibits
them from being built below BFE unless constructed to prevent flood waters from
entering the structures.
According
to the Florida Floodplain Managers Association (FFMA) in its white paper DRAFT Policy and Design Options for Public Restrooms in Special Flood Hazard Areas
2014, 60 percent of communities responding to FFMA’s public restroom survey of
coastal communities reported having non-conforming or non-compliant public
restrooms built below the BFE, in conflict with NFIP regulations. Communities’
staff has expressed to FFMA in the survey and at two statewide conferences and
one national conference that the NFIP regulations are overly restrictive, lack
a definition of allowable uses of public restrooms below BFE, and due to
elevation requirements, are frequently too-costly to construct and maintain. Communities have stated that the regulations
cause the need for costly, extremely long ramps (up to 300-feet in length) that
are maintenance intensive and create additional obstructions to wave
loads. Additionally, the excessively
long ramps can be unsightly and create impediments for mobility-challenged
people (and children and the elderly) who the ramps are
intended to serve.
Communities are reluctant to engage design professionals
to develop plans and specifications for affordable, accessible, and attractive
public restrooms at or above grade, but below BFE, that can withstand the
combination wave and wind loads to meet the intent of the NFIP, if the federal
program finds such structures non-compliant because they are “below the BFE”.
The proposed study provides the following
three elements:
1) Analyze the quantitative extent of public restroom
compliance, document structural challenges, and assess the financial burden for
communities to meet the Florida Building Code (and ASCE 24-14) requirements for
construction of flood resilient and accessible public restroom facilities.
2) Develop example or prototypical design concepts and
schematics for three or more building structural approaches that meet or exceed
NFIP, ASCE and FBC flood and wind load requirements (with any exceptions noted)
to verify if public restrooms may be built below BFE in either Zone V or Zone A
flood zones and meet load requirements for the 1% annual base flood.
3) Conduct an analysis and listing of NFIP regulations,
International Codes and Florida Building Code requirements that must be amended
to enable the construction of flood resistant, accessible public restrooms
designed to withstand the 1% annual base flood elevation loads that may be
constructed below the base flood in Zones V and Zone A.
The research must specify the environmental and landscape
site conditions upon which the design considerations are based and which must
be representative of Florida’s coastal high hazard areas in V and Coastal A
zones and in a riverine floodplains. Such research must include, but is not
limited to, consideration of the following: the Florida Building Code, ASCE/SEI
24-14, FEMA’s Coastal Construction
Manual FEMA P-55 (August 2011), and FFMA’s DRAFT Policy and Design Options for Public Restrooms in Special Flood
Hazard Areas, March 26, 2014.
Urgency/Immediacy for Code Amendments
The Florida Division of Emergency Management (FDEM),
Florida’s agency designated and charged with preparing for, responding to,
recovering from, and mitigating against natural hazard threats, proposed an
amendment to address this matter in the 2015 I-Codes. The amendment recognized
public restrooms as a limited use, unique facilities for which design
professionals should be able to use performance-based codes to meet NFIP flood
resilience and accessibility requirements. Except for the elevation
requirement, the proposed amendment included design and construction requirements
consistent with other design standards for non-residential construction.
As an alternative to FDEM’s proposed I-Code amendment,
Staff of FEMA/FIMA asked FDEM to withdraw the proposed amendment and offered to
work with the State to collaborate through a cooperative agreement to resolve
the matter using a national-level Public Restroom Task Force. FDEM withdrew the proposed amendment favoring
to work with FEMA. Staff of FEMA later
refused to follow through on forming a cooperative agreement with FDEM, but did
facilitate four meetings of a loosely organized Task Force before abruptly
ending the endeavor without resolution.
FDEM has repeatedly asked FEMA to resume the Task Force during the past
two years to bring the matter to closure but FEMA has been unresponsive.
FDEM requests that the Florida Building Commission authorize
and fund research on this matter to ensure that design professionals may
develop reasonable and prudent design and construction requirements based on
performance codes. This may result in better on-site relief to Florida
residents and visitors, and afford communities alternatives to construct flood
resilient, accessible facilities that meet the public need. Once the research
is complete, a well-defined solution may be available that will result in potential
amendments to the Codes and NFIP technical building guidelines that will
benefit all communities in the nation with Special Flood Hazard Areas
delineated on Flood Insurance Rate Maps.
Funding Needed
Exact costs for funding the research are unknown at this
time, but the methods of procurement and availability of qualified
organizations that could conduct the research may be the greatest factor on
costs. FDEM recognizes that one of Florida’s major universities, the University
of Florida, may conduct such a study since the university has several colleges
or schools that have expertise considered useful for the study. These colleges or schools include expertise
and research capabilities in building sciences and construction, engineering,
planning, and recreation and tourism.
The anticipated cost for the research is unlikely to exceed $150,000.
