The City has a deferral agreement with the State of Alaska which requires the City of Kenai to adopt and enforce code standards no less stringent than those enforced by the State. The State of Alaska adopted the 2009 International Mechanical Code in November of this year. I therefore recommend the adoption of the 2009 International Mechanical Code as amended by the State of Alaska in order to comply with our deferral agreement and to consistently enforce the code standards in effect throughout the State.
