Miami Valley officials are only beginning to calculate the longterm impacts of the devastation from last week鈥檚 tornado outbreak. Key is an investigation by FEMA to determine whether Ohio is eligible for emergency aid.

Officials caution it鈥檚 a complicated process that will take time. To see it in action, WYSO鈥檚 April Laissle followed one FEMA team into a particularly hard-hit area of Trotwood.

At the Westbrook Village Apartment Complex, a group of FEMA investigators walk through muddy grass holding clipboards, taking stock of what鈥檚 left.

鈥淚t's hard to tell from down here, but you can see all the roof damage,鈥� says FEMA investigator Steve Cooper. 鈥淚t looks like they had a tarp here. I'm assuming a tree entered the roof or something.鈥�

Roof damage is just one of the problems here.

The building is missing almost all of its windows. Insulation and drywall sit in piles on the lawn.

This apartment complex originally had 312 units. Now, only 72 of them are habitable.

In just a few days, this FEMA team plans to assess these apartments, and survey the rest of the damage all over the county.

The Montgomery County Emergency Management Agency (EMA) estimates more than 2,500 properties suffered some kind of storm damage.

Jay Carey with the county EMA says investigators are trying to figure out what it鈥檒l take for the community to recover from the storm, not just by looking at the buildings, but by talking to residents.

鈥淲e鈥檙e trying to get an idea of the impact, not just in dollars,鈥� says Carey. 鈥淜eep in mind it's uninsured damage we're looking at as well.鈥�

Many of the people who lived in this complex didn鈥檛 have renter's insurance.

That鈥檒l factor in to FEMA鈥檚 overall damage assessment, Carey says.

The agency is expected to finish surveying the damage across Ohio this week.
