The Carroll ISD board of trustees approved $232,754 to purchase security glass and other safety components Jan. 14. The glass will be installed at Carroll High School and Carroll Senior High School. This purchase comes as part of ongoing safety improvements throughout the district, Assistant Superintendent for Administrative Services Matt Miller said. The city of Southlake and the school district entered into an agreement last year to earmark more than $500,000 for school safety and security needs at CISD campuses. In December trustees decided to put $244,446 of that money towards the school resource officer program. The remaining money is to be spent on other safety and security areas the district and the city desires. The total cost of the glass is $465,288, according to district documents. The city will reimburse the district $232,534 for the protective glass project. To pay for the remaining cost, the district will use interest that has been earned on the proceeds from the 2017 CISD bond funds. "We are so grateful for the city," CISD trustee David Almand said.
