Mountain Dell Drainage Improvement Project Background

In 2016 the Coconino County Flood Control District (FCD) completed Initial Engineering Assessments (IEAs) in four areas of the County deemed "Special Flood Hazard Areas" by the Federal Emergency Management Agency (FEMA). An IEA is a tool that the FCD uses to better understand flood risks so that initial, conceptual flood mitigation alternatives can be identified and evaluated.

Based on this IEA information, the FCD Board of Directors approved preliminary engineering and feasibility studies for the conceptual Mountain Dell/Sinclair Wash Drainage Improvement Project.
