The Program for Public Information (PPI) was introduced by the Federal Emergency Management Agency (FEMA) as a new planning tool to provide a step-by-step coordinated approach to flood hazard outreach. Pinellas County followed this approach while developing the Pinellas County Program for Public Information (PPI). For all information about PPI, please visit Pinellas County’s website http://www.pinellascounty.org/flooding/ppi.htm Tarpon Springs is a proud partner of the PPI and will use this space to keep our citizens up to date with meeting information and documents.

What is an Elevation Certificate and why is it Required? An elevation certificate is a document that lists a building’s location, lowest point of elevation, flood zone and other characteristics, according to the Federal Emergency Management Agency (FEMA). It is used to enforce local building ordinances and to help determine flood insurance rates. A community’s permit file must have an official record that shows new buildings and substantial improvements in all identified Special Flood Hazard Areas (SFHAs)are properly elevated. This elevation information is needed to show compliance with the floodplain management ordinance. FEMA encourages communities to use the Elevation Certificate developed by FEMA to fulfill this requirement since it also can be used by the property owner to obtain flood insurance. Communities participating in the Community Rating System (CRS) are required to use the FEMA Online Elevation Certificate (FEMA 81-31).

The Homeowners Flood Insurance Affordability Act of 2014 repeals and modifies certain provisions of the Biggert-Waters Flood Insurance Reform Act, which was enacted in 2012, and makes additional program changes to other aspects of the program not covered by that Act. Many provisions of the Biggert-Waters Flood Insurance Reform Act remain and are still being implemented.

The Biggert-Waters Flood Insurance Reform Act of 2012 is a law passed by Congress and signed by the President in 2012 that extends the National Flood Insurance Program (NFIP) for five years, while requiring significant program reform. This document provides a timeline of significant changes to the program as well as who is affected by them, what will happen, and why it is changing.

The National Flood Insurance Program aims to reduce the impact of flooding on private and public structures. It does so by providing affordable insurance to property owners, renters, and businesses and by encouraging communities to adopt and enforce floodplain management regulations. These efforts help mitigate the effects of flooding on new and improved structures. Overall, the program reduces the socio-economic impact of disasters by promoting the purchase and retention of general risk insurance, but also of flood insurance, specifically.

Private Provider Notice

Private Provider Plan Compliance Affidavit

Private Provider in Special Flood Hazard Area (SFHA)

FEMA Memo on Affidavits

The DEM State Floodplain Management Office has received inquiries regarding use and acceptance of private providers for building in special flood hazard areas. The FBC, Building Chapter 1 specifically does not extend that authority to the flood load and flood resistant construction requirements in Sec. 105.14 exception, and Sec. 107.6.1. The above memorandum, co-signed by Jason Hunter, FEMA Region IV, explains the origin of those FBC provisions and FEMA’s expectations based on the NFIP regulations.

Despite the submission of an affidavit authorized by B107.6, the building official must review plans for compliance with the flood provisions and issue permits and perform inspections to ensure compliance with the flood provisions. Under the NFIP, the community is responsible for ensuring compliance. *The original proposal (SP5255) included both Section 107.6.1 and Section 117; the exception to Section 105.14 was added to proposal CA5082) by amendments for consistency. Please contact (850) 815-4556 or floods@em.myflorida.com if you have questions about the flood provisions in the FBC or FBC-coordinated floodplain management regulations.

What is substantial improvement?

Substantial improvement, as defined in 44 CFR § 59.1, means any reconstruction, rehabilitation, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the start of construction of the improvement. The term includes structures that have incurred “substantial damage,” regardless of the cause of damage and regardless of the cost of repair work actually performed. However, the term does not include: • Any project for improvement of a structure to correct existing violations of State or local health, sanitary, or safety code specifications that have been identified by the local code enforcement official, and that are the minimum necessary to ensure safe living conditions, or • Any alteration of a “historic structure,” provided that the alteration will not preclude the structure’s continued designation as a “historic structure.” Be sure to check the State and community’s floodplain management regulations and building codes to determine whether any local requirements are more restrictive than the NFIP minimum requirements. Some communities modify the substantial improvement requirements in one of two ways: adopting a lower threshold than 50 percent (such as 40 percent or 30 percent) or tracking costs of improvements and costs of repairs over a specific period, referred to as “cumulative substantial improvement.” Some communities adopt more restrictive requirements that affect the design of buildings, such as requiring elevation higher than the NFIP minimum elevation, which is the base flood elevation (BFE).

FEMA 50% Rule Actual Cash Value (ACV) Appraisal

  1. An ACV Appraisal is Defined as: (add the following to appear when clicking on the link) The cost to replace an insured item of property at the time of loss, less the value of physical depreciation. An ACV Appraisal is defined as: The cost to replace an insured item of property at the time of loss, less the value of physical depreciation. ”4.5.3 Actual Cash Value Actual cash value (ACV) is the cost to replace a building on the same parcel with a new building of like-kind and quality, minus depreciation due to age, use, and neglect. ACV does not consider loss in value simply due to outmoded design or location factors. The concept of ACV is used in both the insurance industry and the construction industry. In most situations, ACV is a reason-able approximation of market value. A number of commercial sources of construction cost information are available to support estimating the replacement cost of a building, including industry-accepted guides available from companies such as RSMeans (http://www.rsmeans.com) and the Craftsman Book Company (http://www.craftsman-book.com), among others. These sources allow computation of construction costs based on occupancy, square footage, quality, and regional cost variations. Depreciation accounts for the physical condition of a structure. Depreciation does not take into account functional obsolescence (e.g., outmoded design or construction that pre-dates current codes) or factors that are external to the structure (e.g., reputation of schools or distance to shopping and parks). Commercially available references provide tables and formulas to calculate physical depreciation. These tables and formulas are objective and are used by most professionals in the fields of property appraisal and building inspection. Local officials may consult with a qualified appraiser regarding depreciation, or additional guidance for applying depreciation rates over time is found in FEMA P-84 CD, Substantial Damage Estimator (Section .5).” FEMA P-758, p. 4-15
  2. The Building Department will only accept FEMA 50% Rule Actual Cash Value (ACV) Appraisals

What is a Coastal A-Zone? NFIP flood hazard mapping is generally divided into two categories, V Zone and A Zone. In coastal areas, the A Zone category could be subdivided into “Coastal A Zone” and “A Zone.” Base flood conditions in the Coastal A Zone will be similar to, but less severe than, those in the V Zone; base flood conditions in the A Zone will be similar to those in riverine or lake floodplains. The Coastal A Zone is not shown on the FIRM at present; therefore, communities, designers, and owners will have to determine whether a site lies within a Coastal A Zone. V Zone design and construction standards are recommended in Coastal A Zones subject to erosion, high velocity flow, and/or wave heights greater than 1.5 feet.

What is a LiMWA? The LiMWA is an informational line that can be found on flood maps for some coastal areas. On a flood map, it is shown as a black line with black arrows that point to areas where wave heights are between 1.5 and 3 feet. It also marks the inland limit of the Coastal A Zone.
