At the new Lynnwood High School, there are some spots in which the radios of emergency responders won’t work. That will soon change.

Last week the Edmonds School District Board approved a project to improve radio reception at the building, which opened in 2009.

Fire District 1 and the Snohomish County Sherriff’s Office have reported some radio “dead zones,” most likely caused by the metal structure of the building. They requested that the school district fix the problem. Officials determined the most cost-effective solution is to install a series of transceivers connected to a rooftop antenna.

When the new Lynnwood High School was designed and permitted, it met all code requirements. Since that time, new fire and building codes have gone into effect stipulating that 95 percent of all areas must have signal levels meeting a specific standard.

The project is expected to cost $300,000, which will come out of the building’s original budget. The work is expected to be done this summer.
