The older Williamson Valley Road-area subdivisions of Ho Kay Gan Village and Tonkawa were mostly platted and developed during the 1960s and 1970s and were never subject to formal drainage planning in the past. Significant monsoon-type storms in 2013, 2014, and 2015 have further revealed that a comprehensive drainage study of the more significant drainage paths and watercourses in the area to review existing hydrology and drainage facilities would be helpful in planning and prioritizing future improvements. 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) and Civiltec Engineering have completed an Area Drainage Master Study for the Ho Kay Gan Subdivision and drainage areas. Taken into account were drainage issues identified by the County, the residents, and surveying and hydraulic modeling by Civiltec.
Potential projects to help resolve drainage issues in the project area have been identified and prioritized. Residents in the area are invited to a public meeting for a short presentation and to review the potential projects and see what benefits they may provide.
