State Standards
The Department’s State Standards Work Group was formed in 1990 to develop standards and provide technical assistance to promote consistent, responsible floodplain management and watercourse use on a statewide basis. These standards are mandated by state law, as declared in ARS § 48-3605(A), which states, “The director of water resources shall develop and adopt criteria for establishing the one-hundred year flood and delineating floodplains.”
To accomplish this goal, the State Standards Work Group develops technical materials and training resources by:
- Incorporating input and expertise from local, state, federal and private entities;
- Seeking necessary funding to implement our mission successfully; and
- Providing training opportunities on the proper use of State Standards and related issues in cooperation with the educational community.
Membership (membership )
The State Standards Work Group is composed of representatives from the following agencies and organizations. They donate their time and resources to support the goals of the Work Group:
- The Department’s Flood Mitigation Section;
- Two Urban Counties;
- Two Rural Counties; and
- Arizona Floodplain Management Association (AFMA) Technical Committee
Funding
The State Standards program is funded with donations from agencies and organizations that benefit from and use program materials.

State Standards Training
The State Standards Work Group continues to develop training programs on the proper use of the Standards. Training is provided at various locations around the state at no (or very low) cost. Additional materials are available here.
