I heard of one family that escaped their 1,000 home subdivision in a kayak with nothing but their kids and the pets. Everything they own including cars is now completely submerged along with 1,000 other homes around them. The only way into the house at this point would be with a diving suit. Start doing the math. Would you even want to rebuild knowing you could lose it all again?
Beyond that what does this do to Houston from a business perspective? Will jobs relocate temporarily and if they do will they come back? Epic flooding, total losses, water filled with gators, snakes, and islands of fire ants floating around you, I can imagine a lot of people will leave, the question is where will they go? Dallas is already at capacity and we don't really have the ability to build faster, especially if a ton or resources go into rebuilding Houston.

They'll be fine.
"Unfortunately, the number of displaced residents could be far larger than current media reports indicate," CoStar Group Founder and Chief Executive Officer Andrew Florance said in a new report. "Our property by property review of the apartment buildings in the floodplain reveals an outsized share are low to moderate income households, including those in Southwest Houston where the bayous have overflowed."

Houston’s record rainfall and flooding triggered by Hurricane Harvey will likely make Dallas-Fort Worth even more attractive to relocating and expanding companies, economists and site selectors say.
North Texas and Houston routinely compete when companies are looking to move or expand, including corporate headquarters and other high-profile, job-creating projects.
The havoc of Harvey highlights Houston's proximity to the coast and the risks that come with it, Bernard Weinstein, a Southern Methodist University economist, said in an interview with the Dallas Business Journal.

Both Class I and II permits have raised the minimum finished floor elevation required by the county. Class II permits will now require pier and beam foundations and additional wind design requirements. That means no more slab on grade construction, a standard in the industry. Mechanical and electrical units will have to be elevated to the first floor.
Requiring foundations to be constructed with pier and beam allows water to pass through and be detained beneath the foundation, instead of flowing over a concrete slab on the ground, Pickering said. Pier and beam foundation construction is a more complicated and costly method of construction.
Harris County's old criteria allowed for finished floor elevation to be at the 100-year level plus 18 inches. The new regulations require the lowest finished floor to be at the 500-year flood level plus 36 inches. That means in the floodway, new construction will have to be at least twice as high. The cumulative effect pushes projects up to eight feet higher than previously required.
Currently, homeowners in the 100-year floodplain are required to have flood insurance and build new homes 1 foot above the floodplain. Turner’s proposal will increase that to 2 feet and expand it to homes in the 500-year floodplain.
The drive to include the 500-year floodplain — where there is only supposed to be a 0.2 percent chance of flooding each year — came after homes in that floodplain flooded in three consecutive years. During Harvey, a third of homes in the 500-year floodplain were damaged by flooding and, according to a city study, 84 percent of the structures in the 100-year or 500-year floodplains that flooded during Harvey may have avoided damage if the proposed regulations had been in place.
