This just in from a BHB reader:
New signage was put up along Columbia Heights from Cranberry down past the playground and dog run, changing no parking T 8:30- 11:00 to no parking 11:30-1:00. Traffic enforcement agents were out in force ticketing those who did not notice the change. Also, a no standing area was put up at the cut where formerly Middagh St. ran which now is a walkway. An unsuspecting man waiting at that spot was warned by a passerby.. I am not aware of any announcement of these rule changes, although of course I might have missed it.
