Straight to the permits this Thursday morning.
                
2501 First St. NW: The District will raze a "disused" brick and concrete water filtration plant. This is the McMillan property, but it's unclear from the permit what specific building will be demolished, or for that matter, whether the raze is part of the McMillan redevelopment or the Bloomingdale flood control efforts. I'd bet the latter.
