LINCOLN, Neb. (AP) — The public safety director for the city of Lincoln says the city needs to replace its old emergency radio system and should build four fire stations to improve firefighter response time.

Tom Casady, the city’s former police chief who became public safety director in 2011, has long pushed for a new radio system to replace the 21-year-old current system.

Casady also supports building four fire stations to help meet federal standards that say firefighters should respond to any address within four minutes. He says more than 9,700 addresses in the city fall outside that window.

Over the next three months, a committee appointed by Mayor Chris Beutler will examine ways to pay for the projects, expected to cost more than $34 million.
