Nothing ever remains static on the Rockaway peninsula. There are constant changes to the landscape, particularly in this day of revitalization and growth. Some changes, however, might be considered negative rather than positive. Witness the coming auction at The Ocean Grande, the luxury condominium building at the southern end of Beach 116 Street. When the building was first constructed two years ago, there were many who predicted that expensive apartments would not sell on the shopping street and they are now pointing to the auction of 21 units as proof that they were right. The auction will be held on May 19 and there may be bargains there for condo-seekers.
