The City Council adopted the "General Engineering Standards", which include the Quad City "Standard Details", on June 7, 2016. The intent of the standards is to provide clear and concise direction regarding technical requirements, policies, and processes to facilitate the design and construction of City Capital Projects and private development projects that include public improvements, such as water main, sewer main, drainage, streets, etc, which will be given to the City for long-term operation and maintenance. The General Engineering Standards will be in effect beginning on July 6, 2016.

Comments or questions regarding the General Engineering Standards, please call 928-777-1130.


In April of 2015, the Federal Emergency Management Agency (FEMA) issued new preliminary Flood Insurance Rate Maps for the City of Prescott and portions of surrounding unincorporated areas of Yavapai County. FEMA initiated a 90-day comment/appeal period for the new maps in October by placing public announcements in the Prescott Courier newspaper. The City Public Works Department sent two postcard mailings to all residences impacted by the map changes, published 4 additional advertisements and held two public meetings to provide information and answer questions. The new floodplain maps are scheduled to become effective in the Summer of 2017.

The map changes will affect each property differently. Some homes that were previously mapped as being within the floodplain may now be shown as being outside the floodplain. Other homes that were outside the floodplain may now be mapped inside the floodplain boundary. Other homes that were in the floodplain and will remain within the floodplain may experience a higher or lower Base Flood Elevation that could affect your flood insurance premiums.

If you received notification from the City but were unable to attend the public meetings, you can obtain more information about the changes by using the map link below or contacting the City. Property owners affected by the change are encouraged to learn how the changes will affect them and to purchase flood insurance through the National Flood Insurance Program for any structures that are within or adjacent to a floodplain.

The new preliminary flood maps are available for viewing at the following websites:

Comments or questions regarding the proposed map changes can be forwarded to or by calling the office of the City Floodplain Administrator at 928-777-1130.
