The District of Columbia neighborhood that lays claim to the Washington Convention Center and a flurry of new development also is overrun by vacant, dilapidated properties that stifle the community’s progress, a residents’ group said in a recent survey.

The Mount Vernon Square Neighborhood Association pinpointed 100 vacant properties in the area bounded by New York Avenue Northwest to the south and N Street Northwest to the north, between First and Seventh streets. Of those, 71 were vacant buildings and 29 were empty lots.
