Ski Hill Basin
Project Update
In March 2023, a consultant team working with the Chelan County Flood Control Zone District released the Ski Hill Basin Report, which details the analysis of the basin and mitigation measures that would minimize the flood risks associated with rapid snow melt in the basin.
Project Description
Located just north of the city of Leavenworth, the Ski Hill Basin stretches from the Cascade Range to the Wenatchee River. It encompasses everything from looming mountain peaks, national forest lands and wetlands to a historic ski hill, residential neighborhoods and commercial properties. The Ski Hill Basin is typically covered with snow from December into March, but its summers are dry and hot. In most recent years, the area west of Titus Road has seen much development and growth.
During the winter of 1996, officials with Chelan County and the City of Leavenworth were alerted to increased volumes of runoff within the basin. Some homeowners reported water in their crawl spaces and water running down roadways. In subsequent years, the flooding has continued. It typically occurs during rapid snow melt in late winter/early spring, ultimately impacting both public and private property.
The 2017 Comprehensive Flood Hazard Management Plan, a project of the Chelan County Flood Control Zone District, identified Ski Hill as a top priority for flood mitigation efforts. The report called for an analysis of the basin to determine an action plan.
The FCZD is funding the analysis and hired a consultant team including Tetra Tech, Inc., Perteet, and Grette Associates to complete it.
The analysis is the basis for identifying flood risks and creates a framework for reducing flooding impacts to public and private property within Chelan County and the city limits of Leavenworth. It identifies current conditions and assets, system deficiencies that lead to flood risks, potential mitigation measures and strategies, estimated costs, and prioritization of proposed projects. The analysis is a tool in guiding future capital projects that protect property and the health and safety of the public from flooding.
Community Engagement
In February 2021, the community was asked to view and comment on a “StoryMap.” Using maps and descriptions, the StoryMap detailed the project and asked for the public’s input on six alternatives that will mitigate, to various degrees and costs, flooding in the Ski Hill Basin. The suggested improvements include the construction of enlarged drains and culverts, enlargement of existing flow retention facilities, and up-basin flow and sediment capture facilities.
Using feedback gathered via the StoryMap, the project team presented the top two alternatives to the county. Chelan County commissioners, who serve as the supervisors of the FCZD, chose to proceed with Alternative No. 4, which will look at improving storm water conveyance on Titus and Detillion roads. The consultant also will be looking at ditching and culverts and any opportunities for runoff relief near the Ski Hill Lodge area. A proposed plan, with a budget, is expected to be submitted to the district by early fall.
