Flood Risk in Atascocita & Summerwood

Hi everyone! My dad is considering moving to a suburb in northeastern Houston, and he has his sights on Summerwood and Atascocita (specifically Balmoral). How badly do these communities flood? Have they faced any significant flooding during the major weather events of this past decade (Harvey, Imelda, Beryl, etc)? I spent a fair amount of my childhood in Kingwood, so I'm aware that the region can flood, but I'm under the impression that Atascocita and Summerwood are not particularly flood-prone.
