Codes, Standards, Recommendations for Veneer Wall Repair in Flood Zones
This page includes research, building codes, standards, and references for recommended construction methods to minimize flood damage to veneer-wall constructed buildings. We also cite experts who have provided technical review of this article series.
Some of these standards are best-applied to new construction while others provide detailed repair advice for buildings being repaired or re-constructed after suffering flood damage.
These references support the following masonry veneer wall structure repair articles:
Photo: at this building in Venice, Italy, we see both foundation flood vents used where the building structure includes open space below grade and elevated drain openings in the brick cavity wall.

Excerpt: This bulletin describes design, construction, and planning requirements for the floodproofing of non-residential buildings under the ‘National Flood Insurance Program (NFIP) regulations and how to correctly complete the NFIP’s Floodproofing Certificate for Non-Residential Structures form.
For the purposes of this bulletin, floodproofing means making a building watertight, substantially impermeable to floodwaters.

Comment:
I recently saw your article on remediating flooded brick walls, and wanted to share an approach that you may not have seen before. It maintains a drainage gap behind the masonry and installs closed cell spray foam in the stud cavity, resulting in a drainable, dryable, flood resistant wall. - Tyler Leclear Vachta - by private email to editor 2017/09/29
Pace, Carl E., FLOOD PROOFING TESTS, Tests of Materials and Systems for Flood Proofing Structures [PDF] (1988) AD-A209 380 U.S. Army Corps of Engineers, National Flood Proofing Committee
Excerpt: It was determined by model and prototype tests that brick-veneer and concrete block walls can withstand only approximately 3 ft of static water head without damage. If a building or home is loaded to excessive depths, it can fail instantaneously and possibly result in injury or death to occupants.

Excerpts: Regulation of the use of flood plain lands is a responsibility of State and local governments and can be accomplished by a variety of means, such as establishment of designated floodways and encroachment lines, zoning ordinances, subdivision regulations, and building codes.
These land use controls, most often known
as "Flood Plain Regulations," do not attempt to reduce or eliminate flooding but instead are intended to guide and regulate flood plain development to lessen the adverse effects of floods.
Flood prone communities in the United States participating in the National Flood Insurance Program (NFIP) are required to adopt and enforce
such flood plain regulations to qualify for the sale of federally-backed flood insurance to its residents.

Exterior walls are designed and constructed using barrier or cavity / rain screen wall principles. Exterior Insulation and Finish Systems (EIFS) are typically constructed as barrier walls; masonry is often constructed as a cavity wall. These wall systems are discussed along with common deficiencies that allow water intrusion to occur.
