In the aftermath of Friday's Texas school shooting that left 10 people dead, school districts in the Bay area are making security adjustments as the school year nears end. 

Another school attack just three months after the Parkland school tragedy that left 17 dead in South Florida has parents and students feeling uneasy again. 

Bay area school districts are beefing up security with additional uniformed officers are all levels of schools - from elementary to high schools. 

In St. Petersburg, uniformed officers will be parked in vehicles outside all elementary schools and will continually check school perimeters. 

The Citrus County Sheriff's Office was the first in the state to react following Parkland by placing additional officers at all schools. And in Pasco County, Sheriff Chris Nocco said there will be a heavy law enforcement presence at all schools. 

The same goes for Polk County, where Sheriff Grady Judd has laid out a safety plan for the remainder of the year. 

He said there will be an armed law enforcement officer on every Polk County public school campus for the rest of the school year. In addition, book bags won't be allowed in schools for the rest of the year.

"I never went to school without a backpack, so it's kind of hard to grasp the idea for my kid to have no backpack," said parent Alexis Wilkins.

At Polk County's public high schools, students often see an officer on campuses. However, they are not used to leaving their backpacks at home. 

"Everyone without a book bag, it's kind of eerie almost," said high schooler Matthew Gutierrez.

Some high schoolers forgot to leave their bags at home. Those book bags were taken away for the day. 

Hillsborough County Sheriff Chad Chronister said talks are already underway to add additional security cameras at schools, upgrade fencing and reduce the number of entrances and exits. 

Also, starting Monday, there will be a uniformed deputy at all Hillsborough County elementary, middle and high schools through the end of the school year.

"I, along with Hillsborough Schools Superintendent Jeff Eakins, believe this plan will provide some peace of mind for parents and caregivers and teachers and staff," Chronister said. "We must always be ready to react and adapt when something horrific confronts us without notice."

Bay area law enforcement agencies and school districts said there are no imminent threats but officials are simply taking security steps in an abundance of caution for parents and students.
