Flood Risk Analysis And Mapping Policy - FEMA

Transcription

Flood Risk Analysis and Mapping (Rev. 11)FEMA Policy #204-078-1BACKGROUNDThis policy is applicable to Federal Emergency Management Agency (FEMA) staff delivering Risk Analysis andMapping (Risk MAP), all mapping partners (contractors, cooperating technical partners, and other federalagencies) who perform flood risk projects on behalf of FEMA, and the National Flood Insurance Program(NFIP). Additionally, this policy may be pertinent to states, tribes, territories, local communities, homeownersand their consultants who are interested in the Flood Insurance Rate Map (FIRM) process.This policy updates and supersedes the Standards for Flood Risk Analysis and Mapping – FP 204-078-1(Rev 10) approved on Dec. 11, 2019.The changes with this revision are:Table 1: 2020 Maintenance Cycle: Standard UpdatesStandard Identification Number (SIDs)Standards Change DescriptionSIDs 66, 69, 73, 75, 77, 78, 79, 128, 248, 335Updating to include edits and refinements associatedwith the 2D Floodway Significant Update.SIDs 89, 96Updating to clarify the use of regulatory products andthe applicability of this standard.SID 99Rescinding standard in association with edits andrefinements associated with the 2D FloodwaySignificant Update.SIDs 101, 103, 229, 232, 256, 265, 274, 507Updating to clarify standard and align to currentstandard operating procedures.SID 230Rescinding standard because this is covered by otherstandards and guidance.SID 235Updating to comply with current style guidespecifications.SIDs 264, 272, 279, 280Updating to incorporate clarifications or corrections inthe wording of the standard.SID 415Updated to removed confusing language andemphasize the focus on quality.Page 1

Standard Identification Number (SIDs)Standards Change DescriptionSID 417Align the Standard to current standard operatingprocedures regarding automated creation of ChangesSince Last Firm (CSLF).SID 424Rescinding standard because the tiling structure is nolonger applicable.SID 443Updating to direct information on National FloodInsurance Program policy and claims information toOpenFEMA.SID 628Updating to reflect the automated creation of ChangesSince Last Firm (CSLF) through Customer and DataServices (CDS) tools and removes it from the list ofproducts required to align with model information.SID 630Updating to establish understanding that AutomatedMap Production (AMP) output products will lookdifferent than current requirements, but that is ok.Quality control (QC) will still be required for theengineering and flood hazard information.SID 640To keep Risk MAP IT systems secure and appropriatelyprotect the privacy of individuals who are referenced inRisk MAP data, a User Account Management Plan isbeing established so that all Risk MAP Providersunderstand the protocols that must be followed andmanaged.SID 641Updating as expired Provisionally Accredited Levee(PALs) are emerging issues and HQ requires moreoversight on the use of an expired PAL on an updatedregulatory product.SID 642Updating because seclusion should no longer be usedfor a Risk MAP study unless a specific case or set ofcircumstances dictates its use.SID 643New standard developed to address Coastal ZoneManagement Act (CZMA) consistency determinationrequirementsPURPOSEThe purpose of this policy is to enable consistent performance by identifying the standards that must befollowed in the delivery of the Risk Mapping, Assessment, and Planning (Risk MAP) program. Thesestandards govern the performance of flood risk projects, processing of letters of map change and relatedRisk MAP activities.Page 2

PRINCIPLES1.Ensure consistency in the deliverables of all flood risk projects so that they can support the NFIP and allits stakeholders.2. Ensure a standard level of quality is met for all deliverables of a flood risk project.3. Provide appropriate flexibility to FEMA Regional Offices and mapping partners to accommodate regionaland local variability across the country.4. Enhance the credibility of the NFIP and all flood risk mapping efforts.REQUIREMENTSFlood risk projects, regulatory NFIP map changes and other Risk MAP activities shall be performed in aconsistent manner resulting in quality data and deliverables. The attached set of standards shall be followedin the delivery of Risk MAP.Standards must be implemented based on the effective date and implementation description. Theimplementation description is chosen to avoid cost or scope impacts on existing task orders, cooperativeagreements, or interagency agreements. If the implementation of a new standard as mandated by this policyrequires a change to an existing agreement, coordinate with FEMA to modify the existing agreement asnecessary. New standards may be implemented sooner in coordination with the FEMA Project Officer andContracting Officer’s Representative.FEMA publishes substantial additional guidance to support implementation of and compliance with thesestandards. Users of these standards should also reference this guidance published on FEMA’s web site emas-risk-mapping-assessment-and-planning.This page was digitally signed by Nicholas Shufroon 2020.12.22.Nick ShufroActing Assistant AdministratorRisk Management Directorate, ResilienceDatePage 3

ADDITIONAL INFORMATIONReview CycleFEMA POLICY Standards for Flood Risk Analysis and Mapping #FP 204-078-1 (Rev. 11) will be reviewed, reissued,revised, or rescinded annually.AuthoritiesThe mapping program for the NFIP, implemented through Risk MAP, is established through the National FloodInsurance Act of 1968, as amended and the Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12), asamended (42 U.S.C. 4001 et seq.). The mapping program is governed by the implementing regulations at Code ofFederal Regulations - Title 44 (44 CFR) parts 59-72. The statutes and regulations establish the core requirementsfor the mapping program.This policy represents FEMA’s interpretation of these statutory and regulatory requirements and/or sets forthstandard operating procedures. The policy itself does not impose legally enforceable rights and obligations but setsforth a standard operating procedure or agency practice that FEMA employees and contractors follow to beconsistent, fair, and equitable in the implementation of the agency’s authorities.These standards are to be applied in addition to the legal requirements set out in the applicable statutes andregulations. For the most part, the applicable statutory and regulatory requirements are not repeated in this policy.Readers must refer to the statutes and regulations in addition to these standards.DefinitionsFlood risk projects are projects implemented under the Risk MAP program to engage with communities and provideflood risk information.Guidance is a recommended method to meet the standard. Guidance assumes a working knowledge of commonindustry terminology and methodologies. Accepted approaches are not limited to this recommended approach;mapping partners may use other methods to meet or exceed the standard.Guidelines and Standards Steering Committee is comprised of FEMA headquarters and regional employees andcontractors responsible for maintenance and coordination of Risk MAP standards and guidance.Mapping Partners are FEMA Production and Technical Services Contractors, Cooperating Technical Partners, andOther Federal Agencies (OFA) performing tasks on a flood risk project.Program standards are a required element that supports the vision, goals and objectives of the program. Exceptionsmust be obtained through coordination with FEMA headquarters Risk Analysis Division leadership.Page 4

Risk MAP is the FEMA program that maintains flood maps for the NFIP and works with local governments to increaseawareness of flood risk and provide flood risk information that leads to actions to reduce risk.Standards exceptions are project-specific variances to Risk MAP standards, approved by appropriate Risk MAPofficials.Working standards are required elements of a project that are typically applied by specialists (such as engineers,planners, GIS specialists, etc.).Monitoring and EvaluationCompliance will be monitored through the Risk MAP Quality Assurance Management Plan.QuestionsDirect questions by email to the shared FEMA RMD Guidance & Standards inbox.Page 5
