Conversely, a nuisance should be deemed permanent if it is sufficiently constant or regular (no matter how long between occurrences) that future impact can be reasonably evaluated.Schneider, 147 S.W.3d at 280-81; see also Mitchell v. Timmerman, No. 03-08-00320-CV, 2008 WL 5423268, at *6 (Tex. App.-Austin Dec. 31, 2008, no pet.) (mem. op.) (holding that flooding from every significant rain is permanent nuisance); Pope v. John Kiella Homes, No. 07-06-0146-CV, 2008 WL 1903332, at *3-4 (Tex.App.-Amarillo Apr. 30, 2008, no pet.) (mem. op.) (finding that flooding following heavy rains is a permanent nuisance). In addition, the structure creating the runoff, Mousa's shopping center, is a permanent structure, and such a permanent source is presumed to result in a permanent nuisance.
