Over the last eight years, more than $2 million from grant funding has been used to improve the center.
The purpose of the tour was to show how Wake County is putting federal dollars to work inside the facility. There have been a lot of changes since 9/11.
Improving communication between different agencies has been a key focus. Implementing GPS technology is one of the upgrades the county made, and it helps speed response time when responding to emergencies.
"It brings law enforcement, fire and rescue -- all of us together where one time we couldn't talk to each other," Wake County Sheriff Donnie Harrison explained. "Now, we can. Whoever arrives at the scene can actually tell us what's going on, so it's a big plus to the public."
Representative Miller agreed saying, "When there is one big problem, they can all talk with each other."
Communicating during an event that is unfolding second-by-second is key in keeping the public safer. There are still challenges, including rapid growth of Wake County and the ever changing face of technology.
"There's always a lot of training ahead of the curve," Rep. Price added.
The representatives said they will take the information they gathered during Tuesday's tour back to Washington and use it to ask for more funding.
Additional funding will mean more improvements and technological upgrades for the center in the future.
