Elsa is long gone, but she left a big mess in Greenburgh that people say could have been avoided.

Some residents say the storm damaged their basements, garages, even first stories. They allege a pair of pipes in Troublesome Brook are to blame.

Homeowners say engineers they've hired themselves found that one of the two pipes collapsed, blocking water from running through.

The problem goes back decades and even the mildest of thunderstorms wreak havoc on their homes, they say.

Greenburgh Town Supervisor Paul Feiner says he will investigate two options to help families -- fixing the large underground pipe out of Troublesome Brook, and raising the homes in the flood zone. Feiner says the latter would be more cost effective.

"This is a very major project. According to the commissioner of public works, just hiring a consultant to do paperwork without seeing any benefits would be over a million dollars," he said.

Back in the early 2000s, homes on Babbitt Court in Elmsford were lifted because of flooding issues - and one homeowner says it's helped prevent some damage inside but he must park his cars elsewhere. 

Feiner says he'll be reaching out to his county, state and federal partners and see what funding is available and weigh what is more cost effective - repairing the pipes or raising homes.
