COMMENT OF THE DAY: FURTHER READING INTO YOUR HOUSTON FLOOD AND FIRE CHANCES Jan 2017 FEMA Special Flood Hazard Zone classification changes“Every home is susceptible to flooding. There are not ANY non-flood areas. There are only homes that are more likely to flood and homes that are less likely to flood. The likelihood is expressed, on flood maps, by the single-year probability of being flooded (with some other factors). This does not properly describe the likelihood of being flooded during the course of a longer time period — of, say, a 30-year mortgage. Homes eligible for NFIP preferred flood rates can have up to just less than a 1 percent chance of flooding annually. These ‘preferred areas’ are what the public thinks of, euphemistically, as non-flood areas. Assuming a .009 probability (just less than 1 percent), a home has a 20 percent chance of flooding, at least once, over the course of a 30-year mortgage (look up binomial probability). An alternative way to think about it is that 1 in 5 homes, in preferred flood zones, will flood over the course of a 30-year mortgage. [In that case,] you are actually more likely to experience a flood than a house fire in a ‘preferred flood area.'” [Jardinero1, commenting on Where Houston Floods Outside the Flood ZonesImage of recent flood map revisions: FEMA RiskMap6

COMMENT OF THE DAY: THAT HIGH HORSE WON’T KEEP YOUR FLOORS DRY Flooding Coastal Homes“Wonder how many areas will sue to get out of the high risk zones, only to get flooded years later, have no insurance, and cry foul. Note to those who are able to sue or survey themselves out of a flood zone… buy the insurance anyway! If you are [put] in a high risk zone, right or wrong, you are close enough to warrant the protection.” [Rex, commenting on A Quick Tour of Spots Where FEMA Will Expand Its Flood Hazard Zone In JanuaryIllustration: Lulu

Jan 2017 FEMA Special Flood Hazard Zone classification changes

The areas in red above mark some of the new additions to the legally-gotta-buy-flood-insurance zones on FEMA’s recently revised flood maps. The agency’s interactive online viewer lets you mix-and-match a few data sets for Harris County (as well as Galveston, Fort Bend, and Wharton), compare the old mapped flood zone boundaries to proposed new ones, or look only at what would change — a FEMA spokesperson told Houston Public Media that about 8,000 properties have been added to the list in Harris County, while only about 400 were dropped.

Those acid-green highlights are areas that have been removed from the special flood hazard zone by the updated map (while blue shows areas that have just changed floodplain classification some other way. Bits of brown and yellow in other areas of the map show places added or removed (respectively) from the floodway. The updates above to the mandatory flood insurance zone (legally called the Special Flood Hazard Area) are set to go into effect in January, as shown above. Buffalo Bayou and its tributaries are pretty marked up:

A set of 4 new FEMA disaster recovery centers opened yesterday, sprinkled around the north and west sides of Houston hit hardest by the Tax Day flooding. The locations include a Greenspoint office building right across Greens Bayou from some of the apartment complexes evacuated during the flooding (including Arbor Court). The other centers opened Monday in Meyerland, Cypress, and Spring, and additional temporary help centers might get set up elsewhere around town.

As of yesterday night, FEMA had already received nearly 12,000 applications for post-flood assistance. Harris County reported last week that more than twice as many homes were damaged by the April floods as reported during last year’s Memorial Day flooding. Farmers Insurance agent Peter Zografos told the Houston Press last week that many of the same houses have filed claims a second time: “Some of these homeowners may have to be insured directly with the National Flood Insurance Program due to repetitive claims, [and] basically will be charged more for too many flood claims.”

COMMENT OF THE DAY: WHERE HOUSTON STAYED UNDERWATER AFTER THE MEMORIAL DAY FLOOD Flooded Home“Was there ever any kind of press writeup on why so many homes in Meyerland did not come back from this last flood? I’m saddened by all the vacant lots, and on some streets off Endicott, there are clusters of teardowns. Was insurance plus flood insurance essentially useless for all of those homeowners? Or was it the new city building requirements? Genuine questions, because I’ve been in the area 30 years and this [flooding] seems to have been so much more devastating than Allison (and Ike).” [Heather, commenting on Daily Demolition Report: As Is, Where Is] Illustration: Lulu
