You can find the Economic Case for Coastal Resilience here. With NFIP's pricing approach, Risk Rating 2.0, FEMA addresses rating disparities by incorporating more flood risk variables like flood frequency, multiple flood types river overflow, storm surge, coastal erosion, and heavy rainfall and distance to a water source, as well as property characteristics such as elevation and the cost to rebuild. They are available as PDFs and JPGs for your use. The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. The guide also contains two infographics that you can use in explaining coastal risks and resilience options. It gives background on coastal natural disasters and their effect on communities nationwide-including yours. It can also protect them from disasters for decades to come.įEMA developed the Economic Case for Coastal Resilience guide for communities thinking about how to reduce their risks from coastal hazards. Building resilience against natural disasters can improve residents’ quality of life today. But communities can take action to reduce their losses, speed up recovery and build a stronger future for all residents. Investing in Coastal Resilience Is Worth the CostsĬoastal disasters are dangerous and expensive. If there is a Risk MAP project underway in your community, updated maps and/or other products about flood risk are in the process of being developed which can easily be incorporated into your own local plans, mapping systems and outreach materials. This report adds to a series of publications that include Guidance for Accelerated Building Reoccupancy Programs (FEMA P-2055-1) and Post-disaster Building Safety Evaluation Guidance, Report on the Current State of Practice including Recommendations Related to Structural and Nonstructural Safety and Habitability.Looking for info about hazards other than floods? Visit the Risk Management page. Additionally, FEMA P-2055-2 provides Authorities Having Jurisdiction (AHJ) and local building departments key considerations for customizing their emergency management practices and procedures for large scale cordon area management gleaned from two damaging earthquakes. The report includes damage photos of the various potential collapse modes, and a collapse shadow cordon area is prescribed in accordance with the potential collapse mode in a graphical table. Zones B, X, and C are at the lowest risk, while high-risk zones start with either an A or a V (V zones are coastal areas) on the map. The National Flood Insurance program provided by the Federal Emergency Management Administration (FEMA) makes flood insurance available to everyone in the City. Simply enter a property’s address on the FEMA Flood Map Service Center website, and a map showing its flood zone hazard will pop up. This guide relates the observed damage to a building of a given structure type to a potential collapse mode. The best place to start is FEMA’s Map Service Center. No change to the FEMA P-807 methodology is deemed necessary based on the work of FEMA P-807-1.įEMA P-2055-2 Recommendations for Cordoning Earthquake-Damaged Buildings This guideline introduced a methodology to focus the retrofit on the first story to protect the building from collapse without transmitting excessive additional seismic forces into the upper stories. The intended audience for this publication includes building officials, practicing civil and structural engineers, and government officials interested in developing mandatory or voluntary seismic retrofit programs for SWOF buildings.įEMA originally addressed the risk from SWOF buildings by developing and, in May 2012, publishing Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings with Weak First Stories (FEMA P-807). But according to First Street, almost 13 percent of city properties face that risk. The report is intended to be used by jurisdictions and their consultants to inform decisions regarding ordinance scope and retrofit methods to address this risk from the known earthquake resistance deficiencies in these types of buildings in order to provide additional collapse prevention. FEMA’s maps show just 0.3 percent of Chicago’s more than 600,000 properties inside the 100-year flood zone. (FEMA) FEMA has a little over a dozen flood zone classifications based on the estimated frequency of storms that could cause flooding in an area. It also presents retrofit design examples. This new report provides technical information about the expected seismic collapse performance of common SWOF building configurations, both in their unretrofitted (or original) and retrofitted conditions. The purpose of Guidance and Recommendations for the Seismic Evaluation and Retrofit of Multi-Unit Wood-Frame Buildings with Weak First Stories (FEMA P-807-1) is to advance the understanding of the behavior of older, multi-unit wood-frame buildings with brittle, weak, and torsionally irregular stories, often designated as soft, weak, or open-front (SWOF) buildings and to encourage improved practice in the design of retrofits.
