I somewhat suspect that the new minimum elevation requirements are overkill. Since the completion of the bayou drainage project, it seems to me that significant rain events are drained much more quickly and the water level in the bayou doesn’t rise as much.

In the three years leading up to Harvey, I believe there were three incidents where waters overflowed the bayou, but none of the storms since then have done that (and there have been some significant ones). But it is of course entirely possible that there just hadn’t been the right pattern of rainfall since Harvey that marked the prior instances of flooding.
