FEMA P-348 - Protecting Building Utility Systems from Flood Damage, 2nd Edition (2/17)
The overall objective of this publication is to assist in the construction of buildings with building utility systems that are designed and built so that the buildings can be re-occupied and fully operational as soon as electricity and sewer and water are restored to the neighborhood.
TB1-Openings in Foundations Walls and walls of Enclosures
Provides guidance on the NFIP regulations concerning the requirement for openings in below-Base Flood Elevation foundation walls and walls of enclosures for buildings located in Zones A, AE, A1-A30, AR, AO, and AH.
Provides guidance on the NFIP regulations concerning the required use of flood-damage resistant construction materials for building components located below the Base Flood Elevation in Special Flood Hazard Areas (both A and V zones).
Provides guidance on the NFIP regulations concerning watertight construction and the required certification for floodproofed non-residential buildings in Zones A, AE, A1-A30, AR, AO, and AH whose lowest floors are below the Base Flood Elevation.
Provides guidance on the NFIP regulations concerning obstructions to flood waters below elevated buildings and on building sites in Coastal High Hazard Areas (Zones V, VE, and V1-V30).
TB7-Wet Floodproofing Requirements
Provides guidance on the NFIP regulations concerning wet floodproofing of certain types of structures located in Zones A, AE, A1-A30, AR, AO, and AH.
TB10-Structures Built on Fill near SFHA are safe from flooding
This technical bulletin discusses building techniques, including the use of fill, that can be used to ensure structures are reasonably safe from flooding.
TB11-Crawlspace Construction in SFHA
Provides interim guidance on minimum NFIP requirements as well as best practices for crawlspace construction in the Special Flood Hazard Area.
FEMA P-347 - Above the Flood: Elevationg your Floodprone House
This publication shows how floodprone houses in south Florida were elevated above the 100-year flood level following Hurricane Andrew. Alternative elevation techniques are also demonstrated.
Answers to Questions about the National Flood Insurance Program
This booklet is intended to acquaint the public with the National Flood Insurance Program (NFIP). Despite the highly technical nature of the Program, there has been a deliberate effort to minimize the use of technical terms. This publication is designed for readers who do not need a detailed history or refined technical or legal explanations, but do need a basic understanding of the program and the answers to some frequently asked questions. Readers who need legal definitions should refer to the Standard Flood Insurance Policy and to NFIP and related regulations.
FEMA 54, Elevated Residential Structures
Flooding in residential areas is bound to happen in flood-prone areas resulting in property damage. This manual is for designers, developers, builders, and others who wish to build elevated residential structures in flood-prone areas.
FEMA P-85, Protecting Manufactured Homes from Floods and Other Hazards
FEMA P-85 has been updated to reflect the requirements of the most current codes and standards and to provide a best practices approach in reducing damages from natural hazards. While the original version of FEMA 85 concentrated on flood and wind events, this version also addresses seismic hazards and recommends several multi-hazard resistant foundation designs. Designs are included for wood-framed foundations, conventional concrete and masonry pier foundations, and ground anchors. The ground anchor foundations are based on results from a series of first-of-its-kind saturated and dry soil anchor tests.
Protecting Floodplain Resources - A Guidebook for Communities
This guidebook has been written to introduce officials and citizens at the local level to a basic understanding of natural resources in floodplains and to offer suggestions for creating strategies for wisely managing these important areas. As scientific understanding of ecosystems grows, the importance of conserving and restoring the natural resources and functions of floodplains is increasingly recognized. Historically effective floodplain management was recognized as a necessary task to reduce the loss of life and property. However, floodplain areas are now also recognized as having an intrinsic value of their own as a part of the interconnected ecosystem and an influential role in increasing a community's quality of life
Reducing Damage from Localized Flooding: A Guide for Communities
This guide is intended to help local offices in cities, towns, villages, and counties in the United States understand what they can do to reduce the damage, disruption, and public and private costs that result from the shallow, localized flooding that occurs within their jurisdictions. This is flooding that all too often escapes the attention received by larger floods or those that are clearly mapped and subject to floodplain development regulations.
This time saving, user friendly web-based application will provide licensed land surveyors and professional engineers (Licensed Professionals) with a system to submit simple Letter of Map Amendment (LOMA) requests to FEMA. This tool is designed to make a determination based on the information submitted by the Licensed Professional and allow them to generate a determination from FEMA in minutes, provided all pertinent data is on file and the request is not audited.
NFIP Elevation Certificate
The National Flood Insurance Program (NFIP) Elevation Certificate (EC) (FEMA form 086-0-33) is an administrative tool of the NFIP which is to be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to determine the proper insurance premium rate, or support a request for a Letter of Map Amendment (LOMA) or a Letter of Map Amendment based on fill (LOMR-F).
FEMA P-1037 - Reducing Flood Risk to Residential Buildings that cannot be elevated
This publication presents a range of flood protection measures available as alternatives to traditional structural elevation for homeowners whose residences meet both of the following conditions:
- The residences are existing buildings. This publication is not intended to address construction of new buildings in floodprone areas as these structures should be sufficiently elevated and built in conformance with NFIP and local floodplain management regulations.
- The residences are not Substantially Damaged or Substantially Improved, meaning that the buildings have not sustained damage or undergone improvement (i.e., reconstruction, rehabilitation, addition) where the cost of the damage or improvement exceeds 50 percent of the market value of the building before the damage occurred or improvement began. As with new construction, Substantially Damaged or Substantially Improved structures must be re-built in conformance with NFIP and local floodplain management regulations.
Flood Recovery - Restoring Water Wells
After flooding, private well owners should take actions to ensure their private water supply is safe for consumption. There are five action steps needed to get a flooded well back into service safely: Assessment… Repair… Flushing… Disinfection… Sampling.
First Aid for a Flooded Septic System
Suggestions for preventing damage before, during and after a storm.

Cover Crops for Soil Health
Paul Jasa, Extension Engineer, University of Nebraska–Lincoln. As the Missouri River’s water recedes from fields, producers may need to do some field repairs, dealing with sedimentation, eroded or scoured areas, deposited debris, and still standing water. As harvest of their remaining 2011 crop nears, this work may not seem pressing. However, establishing a cover crop as soon as possible on these fields will aid in recovering and rebuilding the soil.
Cover Crops for Storm-Damaged Fields
Fields that were hailed, flooded, wind-blown, or where planting was prevented this season need cover crops for all of these reasons since a growing crop isn't achieving these purposes now.

Repairing Flood-Damaged Farm Fields
Shawn Shouse, Agricultural Engineer, Iowa State University Extension. Farm fields that have been covered with flood waters may need structural (physical) repair before returning to full production. Flood debris, sand, silt, erosion, and loss of soil structure may all result as residual effects of flooding.

Animas River in NM Live Guage Feed
Treefall Causes Danger
Fast moving water eroding river bank areas and saturating ground led to large trees falling into the river. This caused dangerous conditions in the water and diverted flow over the bank to threaten homes.
2019 Spring Run-Off
It takes a village! Neighbors and SJC employees work to push back flood waters from the Animas River. Sandbags were deployed to keep the homes from being overtaken by the high water.
