HEMPSTEAD - The wet weather caused a major mess for dozens of seniors in Hempstead. MacArthur Senior Village residents say employees from the Hempstead Housing Authority woke them up at 3 a.m. this morning, telling them to move their cars because the parking lot had flooded overnight. They say flooding is an ongoing problem at the residence. When it rains, the creek behind the building overflows into the parking lot, even seeping into the building and parking garage. Officials from the housing authority and the village say the creek is owned by Nassau County, and they say they've been asking the county to help fix the problem. Officials from the county did not return calls for comment.
