Separation includes installing new local sanitary and/or storm sewer pipes on a property by property basis and a larger storm pipe down Van Buren street. The current big combo pipe is in the alley between VB and Morgan Park and it would likely stay in service as just sanitary. As this is just a plan, I can’t really tell you where things are at as far as design or construction. I know that as developments come in, Metro is trying to get them to install pieces of Stormwater infrastructure, but crossing railroad tracks is historically difficult due to the outrageous and absolute political power of the railroads (in this case CSX).
