This course provides engineering and economic guidance to architects, engineers, and local code enforcement officials in retrofitting existing 1- to 4-family residential structures situated in flood-prone areas. The retrofitting measures presented are creative, practical, compliant with applicable floodplain regulations, and satisfactory to most homeowners.
- Identify basic retrofitting methods that are appropriate for residential structures in flood-prone areas.
- Identify National Flood Insurance Program (NFIP) policy, regulations, building codes, and standards that govern retrofitting projects.
- Evaluate the suitability of retrofitting measures for individual residential structures in terms of technical parameters; homeowner preferences; and Federal, state, and local regulations.
- Understand the analyses that are necessary to determine flood- and non-flood-related forces and other site-specific characteristics that control the design of retrofitting measures.
- Apply basic analysis and design methods to implement the following retrofitting techniques:
- Elevation of structures (buildings) on solid perimeter walls or open foundations such as posts, columns, piles, or piers
- Relocation of existing structures outside the floodplain
- Placement of small floodwalls, levees, or berms to protect individual structures (including the installation of temporary or permanent closures for openings)
- Strengthening of foundations, walls, and floors to make them resist flood and flood-related loads
- Installation of temporary or permanent shields or sealants over exterior elements to make structures watertight
- Making building components, including utilities, structural and non-structural components, and contents, water- and damage-resistant during periods of internal flooding of the structure
- Conduct a detailed Benefit-Cost Analysis (BCA) of retrofitting alternatives in order to select an alternative that is both cost-effective and technically feasible.
Program Area(s): Building Science; Floodplain Management; Planning
Selection Criteria: The primary audience for this course is engineers and architects. Floodplain managers and building code officials are also encouraged to attend. Hazard mitigation, planning, zoning, public works, and other building officials with building science knowledge and also those from the private sector, such as engineering firms, may also apply.
Recommended Prerequisites: Participants should complete IS-0279.a, Introduction to Retrofitting Flood-Prone Residential Buildings; and IS-0386.a, Introduction to Residential Coastal Construction. Taking these courses should also help potential participants establish whether they have the necessary level of building science knowledge to take the more advanced resident courses. Registration for recommended prerequisite FEMA IS courses can be found at https://training.fema.gov/is/
This course qualifies for 16 CECs available for CFMs.
