Among the devastating cuts being proposed in Mayor Bloomberg’s budget, two Lower East Side senior centers have been slated for closure. This morning at 11, there will be a march down Avenue D to protest the decision, which would shutter the the Lillian Wald and Jacob Riis senior centers. The march is being organized by Charlotte Miles, tenant association president at the Wald Houses. The march begins at East 10th Street and Avenue D and will proceed down to Houston.
