As development revived within Camp Verde, Arizona, Copper Canyon Fire and Medical Authority (CCFMA) was faced with contention over the requirement for new subdivisions to provide fire flow. The problem was CCFMA did not know if they were correctly interpreting and enforcing the 2012 International Fire Code (IFC) requirement for water supply for fire flow. The purpose of this research was to determine what the legal and appropriate interpretation and enforcement of the 2012 IFC requirement for water supply for fire flow are, as it applies to new residential subdivision development in rural areas.This applied research project utilized an evaluative research method to answer the following questions: (a) What Arizona State laws impact the requirement for water supply for fire flow? (b) How are other fire agencies within Arizona interpreting and enforcing the requirement for water supply for fire flow for new residential development? (c) How did CCFMA previously interpret and enforce the requirement for water supply for fire flow for new residential subdivision development?The researcher performed a literature review to identify previously published materials that address the topic of water supply for fire flow. Additionally, the researcher interviewed the Acting Arizona State Fire Marshal and the Deputy State Fire Marshal. Through the interviews, applicable state statutes were identified and it was ascertained that Copper Canyon Fire's application of the fire code is within state law. Also, a survey was conducted with members of the Arizona Fire Marshals' Association. Survey participants revealed that fire code officials are fairly consistent with the requirement for water supply; all require water supply provisions within new subdivisions; as prescribed by Appendix B in the IFC, NFPA 1142, or fire sprinkler systems. Lastly, a review was conducted of existing subdivision documents. The identified documents revealed the water supply requirement for new subdivisions was enforced by Copper Canyon Fire as early as 1994, and some form of water supply was required in all subdivisions that were reviewed by the fire district.Through the research, it was determined that Copper Canyon Fire's current interpretation and application of the IFC's requirement for water supply for fire flow is legal and appropriate. However, it is recommended that Copper Canyon Fire create a written policy delineating when water supply is required and under what conditions would alternative water supplies be acceptable. It was also recommended that dialogue occurs between fire code officials and elected officials and developers to assist with education and understanding of requirements.
