Mitigation Practice

One of the most cost-effective ways to safeguard our communities against natural disasters is to adopt and follow hazard-resistant building codes. Not only are casualties reduced, but the cost of building damage is also reduced during a natural disaster. Building codes also help communities get back on their feet faster by minimizing indirect costs such as business interruptions and lost income.

NFIP News

Communities that participate in the National Flood Insurance Program (NFIP) adopt and enforce regulations and codes that apply to new development in the Special Flood Hazard Area (SFHA). To improve resiliency and reduce future flood damage, these development regulations and codes also apply to existing struc-tures in an SFHA with proposed “substantial improvements” or repair of  “substantial damage.” Any structure modified more than 50 percent may be de-termined to be substantially improved or substantially damaged (SI/SD). Local community officials (typically floodplain administrators) are responsible for SI/SD determinations.
Does your community have an established Substantial Improvement/Substantial Damage (SI/SD) process? Or has your community already imple-mented some of the essential components of the process: permitting, formal outreach, trained assessors? This Community Checklist will help you quickly de-termine which of these critical components your community has in place.

Answer the following questions pertaining to each of the major steps in the SI/ SD process to help determine if your community is ready for an in-depth review of your SI/SD procedures. If you answer “yes” to 10 or more questions, your community is ready to complete the Guided Community Self-Assessment. The Guided Community Self-Assessment will walk you through a more detailed eval-uation of your community’s existing resources and the current strategies in place for SI/SD implementation.

If you are unsure about the process, or if your community is unable to answer “yes” to 10 or more questions, please contact the state NFIP coordinator/state floodplain manager and/or FEMA for technical assistance on how your community can get essential SI/SD components in place.

Additional Resources:
Information on the NFIP regulations can be found online: http://www.fema.gov/national-flood-insurance-program/laws-and-regulations.

FEMA 758: Substantial Improvement / Substantial Damage desk reference is the principle source of guidance for how to define and regulate SI/SD and provides detailed information about the inspection and determination process.

FEMA 784 (The Substantial Damage Estimator Tool – 2017) provides a standardized approach to data collection management and the determi-nation of substantially damaged structures for local officials. This tool also includes template determination letters communities can utilize.

Utah Risk MAP Corner

We wanted to give you information on a great new Discussion Paper written and published by ASFPM Stormwater Management Committee. Here is the introduction from the paper and a link to the rest of the story.

Urban Flood Hazards: Challenges and Opportunities ASFPM Storm-water Management Committee.

INTRODUCTION: Urban flooding is a multifaceted hazard and has numerous causes. As defined in the recently published summary report of the 2019 Gilbert F. White National Flood Policy Forum published by the Association of State Floodplain Managers (ASFPM) Foundation, Urban Flooding, Moving Towards Resilience, urban flooding is defined as “flooding that occurs in a densely populated area. Whatever the specific cause(s) of inundation—cloudburst, hurricane, groundwater seepage, river overflow, infrastructure failure stormwater systems are overwhelmed, and water accumulates in the paved-over, built up urban environment with nowhere to go.” The impacts of urban flooding, both financial and social, pose significant challenges to local government leaders, managers, and the citizens who reside in these at-risk communities. This discussion paper, developed by ASFPM’s Stormwater Management Committee, focuses on one specific area of urban flooding, mainly areas outside of riverine and coastal flooding zones that are inundated due to surface runoff, i.e. areas where excess stormwater runoff exceeds the conveyance capacity of pipe and roadway systems, resulting in flooding that inundates structures and prevents safe access for emergency vehicles and personnel. Specifically, this paper seeks to provide a discussion of the associated challenges of urban flooding, concepts related to planning and mitigation to reduce future food losses, and recommendations at the local and national scale to address urban flooding in communities nationwide.

This paper provides background and discussion; however it does not represent a position or policy of the ASFPM, a non-profit organization dedicated to the No Adverse Impact approach to reducing flood losses and protecting floodplain functions and resources in the Unit-ed States. (floods.org)

Silver Jackets

USACE Silver Jackets at the Be Ready Utah Webinar

Its 2020, Need We Say More? Utah State’s official emergency preparedness campaign, Be Ready Utah, recently held a public virtual conference to discuss preparedness for different disasters that have impacted the state this year. The two-day conference (13 – 14 November) held four different sessions each day. Sessions covered: pandemic preparedness, earthquakes, flood after fire, surviving without power, water storage, disaster mental health, conversations on preparedness, and disaster myths. The initial in-person presentation was scheduled for 13– 14 March but was cancelled due to COVID-19. The rescheduled virtual event in November was full, with over 140 participants and included interested homeowners to emergency management experts from all levels of government.

The U.S. Army Corps of Engineers (USACE), Sacramento District’s Flood Risk Management (FRM) team members, Mr. Hunter Merritt, Ms. Elise Jarrett, and Ms. Danae Olsen collaborated with the Utah Division of Emergency Management’s Ms. Kathy Holder to discuss current flood after fire efforts and preparedness. The presentation gave a brief overview of the USACE’s role in preparing for post-wildfire flooding hazards, emergency preparedness, and flood risk preparedness.

The Silver Jackets motto “Many Partners, One Team” was highlighted when discussing current flood after fire support to the Utah communities of Mapleton and Saratoga Springs. Both communities have experienced wildfires this year and the FRM team discussed how bringing together emergency management officials at the city, county, state and federal level, will better inform both Mapleton and Saratoga Springs of their flood after fire risks and generate ideas to mitigate those risks. One of the risk-mitigating tools mentioned was the Flood After Fire Toolkit. This toolkit has been developed for California and is easily transferable to communities across the mountain west. The FRM team also shared an upcoming (17 November 2020) free online training from the Watershed University, Preparing for Floods after Fires: Tools and Teams with webinar attendees.

After introducing the USACE and Silver Jackets flood after fire support in Utah, the FRM team got into the bulk of their presentation and took participants on a journey through the hazards that can persist for weeks, months or even years following a wildfire. One of the main post-wildfire hazards covered in the presentation was debris flows. Post-wildfire debris flows occur when water runs downhill through burned areas creating major erosion and picking up large amounts of ash, sand, silt, rocks, boulders, and vegetation (trees, shrubs, plants). The anatomy of a debris flow was covered in detail with graphics that stressed how fast moving and highly destructive a debris flow can be. Throughout the presentation, the FRM team encouraged overall flood and debris flow preparedness and gave practical tips for community members such as “Do not walkthrough moving water or attempt to drive through flooded areas.”

During the question answer session, Ms. Jarrett responded to a question regarding how wildfires effect soil properties by explaining that “When the ground burns at a high intensity for a long enough duration the soil particles, which include water repellant compounds, begin to vaporize and condense. When this happens a water repellent soil layer is formed causing water that otherwise would absorb into the ground to now run off downhill, which can lead to flash flooding and debris flows.”

Overall, Ms. Olsen said, “the presentation went really well” and she and the whole FRM team are excited about continuing to build on the Be Ready Utah webinar momentum through future Utah flood risk education outreach and workshops.
