Borderstanians: Still cannot find out why there are “No Parking” signs and orange mesh fencing around the tree boxes on 15th Street NW between P and Corcoran Streets. But, if you’re parked there — both sides of 15th are marked — be sure to move your car before 7 a.m. between Monday, August 25 and Saturday, September 6. Looks like some extended work for almost two weeks. The parking ban is in effect until 4 p.m. for those dates. Saturday (tomorrow). There may be “No Parking” signs south of P Street NW as well — don’t know!
