Robin hits on what is likely the key point in TX, extensive development that did not take into account where the water would go. Up here, all large development has to dial in where the water will go that pavement and roofs displace from ground absorption. Retention ponds are a standard design component for housing subdivisions and large commercial development. Its been this way for at least 30 years. My last home in MA was in a 10 lot subdivision started in the mid-80’s and we owned a couple acres in common for a retention pond. Our homes were up high and not subject to flooding with the retention pond being there to ensure building our street and homes didn’t cause flooding downstream. Newer subdivisions have much more efficient retention pond designs that might just displace one house lot. Ours was definitely over-engineeered.
