County survey crew working in Number 1 Canyon drainage

Wenatchee’s Number 1 Canyon can be characterized as having a steep channel throughout its 6.8-square-mile basin, allowing for mud, rock and other debris to flow down through the channel during heavy rains or flood waters that occur on the order of 10-year and greater recurrence intervals.  When this happens, flooding of private and public property occurs, leaving costly cleanup to homeowners, Chelan County and the City of Wenatchee.

In June, Northwest Hydraulic Consultants of Seattle, or NHC, was hired by the Chelan County Flood Control Zone District (FCZD) to complete a needs analysis of Number 1 Canyon. The $114,500 project is being paid for by the FCZD.

The needs analysis, sometimes called a gap analysis, will analyze the basin’s conveyance as a whole and determine where and what is needed to minimize the damage experienced from this type of flooding event. It will be a tool in guiding future capital projects that protect property and the public’s health and safety from flooding.

Chelan County’s survey crew is playing an important part in this process, as the crew is gathering the necessary data for the needs analysis. The crew is recording the natural and artificial physical features of Number 1 Canyon, both in the city and county limits. The county’s survey crew uses clearly marked vehicles. It does not do work on private property.

If you have a question about the project, please contact Chelan County Public Works directly at 667-6415. Or email us at fczd@co.chelan.wa.us.
