HOW THEY’RE AVOIDING FLOODING FAR UPSTREAM FROM DOWNTOWN HOUSTON How was developer Newland Communities able to lift the first cohort of 6,200 planned new homes out of the 100-year floodplain in Elyson, its Katy Prairie development just west of the Grand Pkwy. at FM 529? Easy: by raising the lots 1 ft. with dirt taken from other areas of the site. (An additional 12 to 15 in. of elevation came from the slab foundations on which the houses rest.) The fill allowed the company to obtain letters of map revision for more than 300 home lots in 2016 — and “to tell buyers, accurately, that their homes were not in the 100-year flood plain.” The results: “The company reported in September that Harvey had flooded streets in the development, but no water entered any of the 94 houses occupied at that time. The risk of flooding could increase, however, as more structures are built on the property.” [Houston Chronicle] Partial map of Elyson: Newland Communities
