Arvada Fire and the Fairmount Fire Protection District are urging voters to support a merger of the departments.
Amber Oeltjenbruns with Fairmount Fire said district operations have become more difficult over the past several years.
"Everything changed, right? We know that in the last several years, everything's gone up. That's no exception for our fire service. Our apparatus is more expensive, our supplies are more expensive," said Oeltjenbruns.
Normally, it takes 17 firefighters to respond to a scene, according to the district. At any given time, Fairmount has seven and often has to rely on neighboring fire departments for help.
"We're only able to give our community 7 a.m. to 7 p.m. ambulance services," Oeltjenbruns said.
