The Sublimity Fire District provided extensive comments about water supply and water supply requirements. The full comments are available in the file. Applicants are advised to contact the Fire Department directly: ahume@sublimityfire.com or 503-769-3282. Regarding water supply, this property is located in our rural area and has no existing water supply that the district is aware of. The placement of an additional dwelling would cause the property and existing dwelling to potentially need to update to meet current water supply requirements. Following is the standard for rural water supply. Required Water Supply: An approved water supply capable of supplying the required fire flow for fire protection shall be provided to premises on which facilities, buildings or portions of buildings are hereafter constructed or moved into or with the jurisdiction. See Appendix D108, “Uniform Alternate Construction Standard for One- and Two-family Dwellings.” Fire-Flow Calculation Area: The fire-flow calculation area shall be the total floor area of all floor levels within the exterior walls, and under the horizontal projections of the roof of a building, except as modified by area separations (OFC B104.2) and Type IA and IB Construction (OFC B104.3). (OFC B104.1). Type of Water Supply: A water supply shall consist of reservoirs, pressure tanks, elevated tanks, water mains or other fixed systems capable of providing the required fire flow. Fire-Flow Requirements for Buildings in Protected Areas without Adequate and Reliable Water Systems: The provisions of Section B107 are intended for use by the fire code official in protected areas in which adequate and reliable water supply systems do not exist. In determining the fire flow for buildings, the fire code official is authorized to utilize the following nationally recognized standards: NFPA 1142 the International Wildland-Urban Interface Code or the ISO Guide for Determining Needed Fire Flow. (OFC B107) Modifications: Decrease – the fire code official is authorized to reduce the fire flow where the development of full fire floor requirements is impractical based on, but not limited to, the following: type of occupancy, type of construction, location on property, floor area, height and number of stories, yards as defined by the International Building Code, fire walls and the fire-fighting capabilities of the jurisdiction. (OFC B103.1). Increase – the fire code official is authorized to increase the fire -flow requirements where conditions indicate an unusual susceptibility to group fire or conflagrations. An increase shall be not more than twice that required for the building under consideration. (OFC B103.2) Fire Service Features and Timing of Installation: Where fire apparatus access roads or a water supply for fire protection are required to be installed, such protection shall be installed and made serviceable prior to and during the time of construction except where approved alternative methods of protection are provided. (OFC 501.4) We require that the engineer/builder for the property owner do an assessment for water supply and provide us with the results and plan for meeting the requirement. The engineer/builder and property owner may also meet with me to discuss water supply requirements and alternatives to meet these requirements. All other contacted agencies either stated no objection to the proposal or failed to comment. 6.
