An end to Lents flooding?

There are more than 700 households in Johnson Creek’s 100-year floodplain, an area subject to devastating floods predicted to occur once per century, or, put another way, with a 1 percent chance of happening in any given year. Most are in the Lents neighborhood, with a smattering in Powellhurst-Gilbert, two of Portland’s neighborhoods with the greatest concentration of affordable housing.
