Engineering & Natural Resources

The Engineering and Natural Resources Department has responsibility for the survey, design, engineering, planning and management of the County's floodplains, transportation and drainage systems and natural resources. This includes the review of civil site plans for construction, permits and inspection for right-of-way improvements, encroachment, and floodplain use permits.

Cochise County Floodplain Regulations

Staff requests amendments to the “Cochise County Floodplain Regulations” (initially adopted in 1984 and revised several times since then). The proposed amendments encompass several changes to comply with Arizona Department of Water Resources Model Ordinance, including updated definitions, a requirement that all habitable structures be elevated one foot above grade, and the addition of Section 5.9 Standards for Agriculture Structures and Agriculture Accessory Structures. These regulations apply to the unincorporated areas of the County and the Cities of Benson, Bisbee, Huachuca City, and Tombstone. All other cities in the County have opted to manage their own floodplain requirements.

Interested parties are encouraged to review the entire draft.

Flood Control District

The Flood Control District, a division of this Department, serves as a steward of the County's natural resources to guide residents about flooding and erosion with education on flood hazards, building requirements and information about the National Flood Insurance Program, in order to reduce flood damage and maintain the environmental benefits provided by floodplains.

Floodplain Use Permit

Floodplain Use Permits are issued by the Flood Control District of Cochise County for development in a floodplain, including extraction of sand and gravel or other material. Even if you may not need a building permit for your project, if you are doing work within a designated floodplain, you may be required to obtain a Floodplain Use Permit before you build, grade, fill, install any type of wall or fencing, or perform any other man-made change to the property. Please note, Agricultural Properties are not exempt from Floodplain requirements. Visit the Citizenserve Online Portal to apply for permits.
