After Long Islanders saw homes flood, cliffs give way and small dams break this week after Sunday's storm, one Stony Brook professor said it may happen again and again.

And part of the reason behind it is the Island's old and outdated infrastructure.

"The state of the infrastructure, they're falling apart, there is a lack of maintenance and repair," said Ali Farhadzadeh, associate professor at Stony Brook University's Department of Civil Engineering.

Neighbors on Woolsey Avenue in Glen Cove say they have infrastructure concerns after they say Sunday's storm didn't just flood their street, they say some backyards were under several inches of water.

After the flood waters cleared, neighbors tell News 12 they peered down into the storm drains and they found debris and possibly a collapsed pipe.

"The reality is we've noticed some of the pipes aren't connected, we've noticed some of them are clogged, I mean you've seen the picture of the one that's completely clogged," said Sonna Allen.

On Tuesday, Glen Cove Mayor Pamela Panzenbeck told News 12 about the photo of the suspected blocked pipe that DPW will be there tomorrow to assess where that concrete is coming from and remove it.

As News 12 has reported, Panzenbeck also says the city is looking to bring new storm drains to the area to ease what's become regular flooding.

The mayor also says that a plan to possibly bring new storm drains to the area around Woolsey Avenue is moving forward and an official proposal is now in the works.

"That's what we've wanted, you know we want, we want more drains on Poplar and Chestnut because their water comes here and that's the issue," said Linda Melbinger

Farhadzadeh said Long Island's infrastructure is outdated and some of it is crumbling.

He says it also wasn't built to withstand the frequent storms and heavy rain we've experienced.

"These are not an isolated event, things like this could happen again and again and do whatever it takes to be prepared," said Farhadzadeh.

The professor also says now is the time for communities to upgrade their systems and not to wait for the next big weather event to happen.

He says that could end up costing us more in the long run.

"We have to really go back and revise those maintenance guidelines, maybe we have to maintain more frequently, we have to probably allocate more budget for that kind of maintenance activities," said Farhadzadeh.
