The Hogans greenway is, at this point, nothing more than a sidewalk and a few minor amenities(its a start, so Im not complaining).
The creek itself will eventually be worked on under the Army Core of Engineers Aquatic renourishment program (Congress will probably allocate about 200K to design work next fiscal year). Sadly, this also is not a full fix. This will certainly help beautify the creek, and make it a healthier creek (aquatic health), but the industrial contamination will remain and the architecture wont be addressed. There is not a total Hogans Creek plan yet on the table, Im guessing because of the huge cost that will likely be associated with it.
The best approach may be to go after a commercial redevelopment of the creek, downstream, THEN have money included for the rest of the creek, State St north as part of that project that will help with parks, remaining Klutho architecture, and creek contamination.
