The chief of the fire department or the chief’s designee shall determine and specify, after giving notice by mailing to persons whose names appear on the property tax rolls maintained in the Snohomish County assessor’s office in connection with said property, and to the current occupier(s) and by posting a copy of said determination upon the premises in a conspicuous place, access roadways of not less than twenty feet of unobstructed width for fire department apparatus and other emergency equipment and personnel. Said lanes are authorized on streets or ways open to the public or where, because of the congregating of people or the stopping, standing or parking of vehicles, there exists an especially hazardous condition in case of fire or other disaster. Provided, building sites which contain more than one hundred parking spaces shall be designed with access lanes and fire lanes not less than twenty feet in width, forming a continuous route or loop connecting at both ends with public streets. In parking lots containing less than one hundred parking spaces emergency access shall be provided subject to approval of the fire chief or the chief’s designee. Emergency access shall be provided to within fifty feet of any multiple-family building. Provided further that if any of these requirements are impractical due to the peculiarities of the site and/or existing buildings, other provisions for emergency access may be approved by the fire chief or the chief’s designee.
