We’re talking about the long-debated Harrisburg rail line extension, for which three residents of the East End took to the Chron op-ed pages to make their case for their preferred solution.
East End residents worked for years with Metro to work out a solution for the light rail to cross the “east belt” heavy-rail trunk line near Hughes Street. Two and a half years ago an underpass was deemed the best option to cross the railroad tracks because it would preserve the urban character of Harrisburg Boulevard, the commercial and cultural spine of the East End.
Metro now says an overpass is the only option. Metro tells us they have found an underground plume or accumulation of gasoline in shallow groundwater that might pose a liability if it moves under adjacent properties due to the construction of the underpass. There is no danger. It is strictly an issue of liability, based on perception alone.
The contaminated plume in question occurs only in the eastern half of the underpass excavation zone, and at most is only 2 feet thick. Contaminated soil thus makes up only about 10 percent of the total volume of the area to be excavated. This amount is not a deal-breaker for the excavation. Procedures are in place to deal with this kind of contamination during construction, and Metro was fully prepared to deal with this until it started worrying about the lateral underground migration of the plume.
These kinds of contaminated water bodies occur all over Houston. So much so that the city, in conjunction with the Texas Commission on Environmental Quality, has a procedure that allows contaminated zones of groundwater that pose no human risk to be left in place with limited or no liability on the part of landowners who had nothing to do with the original contamination. This is exactly the situation of the Harrisburg Boulevard plume.
There are relatively few viable businesses today along the underpass construction zone on Harrisburg, which is exactly how it will stay if an overpass is built there. Let’s not make decisions based on the used-car lots and pawn shops that are there today. Let’s make those decisions based on what is coming if we do the right thing. This is a generational decision.
See here and here for the background. It seems to me that the real issue here, going back to the bad old days of David Wolff and Frank Wilson, is that it costs more to build an underpass than an overpass, and Metro – which is paying for the Harrisburg line with strictly local funds – has been reluctant to spend the extra money. I can understand that, but at some point you have to recognize reality and try to accommodate a community that has been strongly pro-rail and strongly anti-overpass. Before the discovery of these underground plumes, the New Metro agreed to build an underpass with some financial help from the city. If the price of the underpass is now higher because of this discovery, Metro and the city owe it to the East End residents to try to figure out a way to absorb this extra cost, or to find some other source of funds to help cover it. Surely there must be some way to do this.
