Ash Fork, Arizona, located on Historic Route 66 is an historic community of approximately 500 residents, which has an aging drainage infrastructure system. It became the “Flagstone Capital of the World” as officially bestowed upon the town in 2014 by the Arizona House of Representative via passage of HR 2001. The first post office was established in 1883. The Town economy is typically based on flagstone quarries, the BNSF Railroad, tourism, School District and government employment. Most of the drainage infrastructure is antiquated and unmaintained and the community has little or no documentation on the facilities.
The objective of this study is to identify the existing infrastructure system, determine the condition and operating characteristics of the system, identify the existing drainage tributaries, and provide a program for drainage improvement projects including estimated funding requirements. The primary deliverable of the study is the Ash Fork Area Drainage Master Study (AFADMS) report to be used as a regulatory tool and for future drainage improvement planning. While the Flood Control District has been working with the Public Works Department to clean and maintain some of the drainage infrastructure that is currently present in this area, a formal Area Drainage Master Study (ADMS) will help to provide guidance in budgeting for other potential drainage solutions in future years. The development of an ADMS is a typical solution to determine an approach for resolving area-wide drainage issues and upgrades for a neighborhood or community.
The Yavapai County Flood Control District (YCFCD) has entered into a contract with the Prescott firm Shephard Wesnitzer, Inc. to develop such a study. This contract includes a formal assessment of the area’s hydrology, significant drainage infrastructure, and to develop priority ranking and conceptual design solutions of several identified improvements to address known and discovered problem areas.
