City of Corvallis police officers and firefighters have ratified new contracts with the city. The contracts were approved unanimously by the City Council at Monday night’s meeting at the downtown fire station. Firefighters represented by the Corvallis unit of the International Association of Firefighters had a clause in their six-year deal that allowed them to re-open wage negotiations after three years. Members will receive 4 percent raises in June 2018, with lieutenants, fire prevention officers and fire engineers receiving an additional 2 percent. In December, all unit members will receive 2 percent increases.
