[quote=Anonymous]The picture linked is at the end of King St (Union) where it meets the waterfront.

That area always floods because everything east of Lee St is actually part of the Potomac, which is why it was formerly known as Water St.

The other areas that have had notable flooding are also former streams and low lying areas. Basic maintenance and even attention has been lacking, compared to the amount of time the city and council spends on everything else, but there’s nothing magical about the flooding and no it’s not climate change (in an of itself). That’s pop culture science. Surprise you build over or in a river, which isn’t static, eventually it comes back.

NOAA updates it’s 30 year weather averages every decade, from which FEMA models flood zones, with community input (typically people try to remove themselves from flood zones because it obligates extra and special insurance). This primarily affects Arlandria and maybe the Waterfront.

Even with 2100 predictions, mean sea level rise is projected at “only 6 feet”. That’s bad, but that also isn’t water world. Not that your typical environmentalist can count or cite data.

Secondary impacts to the statistically probability of 1/100 year flood (1%) being 1/50 (2%) which then dictates storm water capacity.

The current storm water project, mandated by Democrats in Richmond (and Democrats in Alexandria tried to weasel out of), is for storm water quality, not expanded neighborhood capacity.

In other words the quarter billion the city is spending, doubling the storm water fee, doesn’t address increased rainfall.

Overall this is a disconnect in priorities, and too many BS positions, including outreach, instead of actually doing what they should already be doing. Cleaning the storm drains, expanding capacity, by which we’re talking about an 8” pipe.

Not wetlands, not some overgrown stream, not an infill housing site that won’t appreciable add to runoff in the area (and is the city’s responsibility and interest anyway). And certainly not the other stupid priorities of the city, from a bike lane no one uses (and I’m an avid cyclist), to hitting a useless racial equality officer.[/quote]
