Per City code 4-6-060 frontage improvements are required for new construction in excess of $150,000. a. The proposed project fronts NE 4th St along the north property line. NE 4th St is classified as a Principal Arterial street with an existing right-of-way (ROW) width of approximately 84 feet per the King County Assessors map.

Decision Criteria: Whenever there are practical difficulties involved in carrying out the provisions of this Title, the Department Administrator may grant modifications for individual cases provided he/she shall first find that a specific reason makes the strict letter of this Code impractical, that the intent and purpose of the governing land use designation of the Comprehensive Plan is met and that the modification is in conformity with the intent and purpose of this Code, and that such modification: a. Substantially implements the policy direction of the policies and objectives of the Comprehensive Plan Land Use Element and the Community Design Element and the proposed modification is the minimum adjustment necessary to implement these policies and objectives; Project conditions: The Fire Station is a necessary element for increased population growth and is consistent with the City of Renton 2024 Comprehensive Plan. b. Will meet the objectives and safety, function, appearance, environmental protection and maintainability intended by the Code requirements, based upon sound engineering judgment; Project conditions: Vehicles responding to emergencies require an exit route that is un-hindered to the extent possible. For safety, vehicles exiting in an emergency will utilize sirens and lights to warn pedestrians and vehicles. There is no known change to environmental protection and maintainability. c. Will not create substantial adverse impacts to other property(ies) in the vicinity; Project conditions: Adjacent parcel properties are not affected and the Right of way improvements are not adversely affected. d.

Can be shown to be justified and required for the use and situation intended; Justification The driveway width is necessary for the following reasons: RRFS #16 Modification Request Page 4 a. The new facility is required to provide adequate space (4’) between doors and door width (14’) to meet 3'-0" clearance between apparatus when apparatus doors are open. b. The apparatuses need to respond to emergencies while heading straight from the building: a. A wider exit driveway allows decreased vehicle turning which reduces strain on the undercarriage and tires of heavy emergency vehicles. This is of particular concern at FS #16 due to the turning side slope that is dictated by the longitudinal slope of NE 128th St. b. The emergency response time is decreased by a shorter turning requirements, due to a speed and efficient wait time for a traffic opening. c. The vehicle must proceed completely out of the bay until it turns, and the site is limited to a 70-foot driveway.
