There are three aspects to our flood mitigation efforts: local, regulatory and regional. While, as the name implies, our ongoing Regional Drainage Improvement Program fits squarely within that third category, one of the deliverables in the first phase scope of work is very much regulatory in nature. Over the past several months the Program engineering team has assisted staff and our citizen Building and Standards Commission in proposing revisions to our drainage design and flood damage prevention regulations, which have now been adopted by Council.
It was, candidly, a tedious and highly technical (some would say boring) deliberation, which made it easy to lose sight of what these amendments are all about. The major takeaways are that (1) based on best available science (i.e., the most updated floodplain maps), new homes will generally have to be built one foot higher than the minimum required currently; and (2) we’ve now formally incorporated the commercial drainage standards, borrowed from the City of Houston, that we’ve historically utilized but not previously codified, to go along with our existing residential drainage standards.
