In 2006, Mountlake Terrace, Shoreline and Edmonds combined resources to hire Clear Creek Solutions to complete a Lake Level Analysis (PDF) project that includes computer models for storm water flow.

Joint Watershed Basin Action Plan

In December 2007, 6 jurisdictions in the Lake Ballinger/McAleer Watershed began discussions related to support of a joint Watershed Basin Action Plan. Discussions were also held with State Senators and Representatives and with our Federal Congressional delegation. After adoption of resolutions by each of the 5 cities in the Watershed along with Snohomish County, an interlocal agreement was drafted and adopted by the 6 agencies to develop a Strategic Action Plan to outline specific goals to protect the Watershed. The Action Plan was developed with the help of a $200,000 appropriation through the Department of Ecology from the State Legislature. The Action Plan was completed in June 2009.

Interlocal Agreement of Jurisdictions

In 2008, all 6 local jurisdictions within the Lake Ballinger/McAleer Creek watershed (Lake Ballinger/McAleer Creek map (PDF)) joined together through an interlocal agreement (PDF) to prepare a strategic action plan that addresses issues related to water quantity and water quality within the drainage basin. The cities of Edmonds, Lake Forest Park, Lynnwood, Mountlake Terrace and Shoreline along with Snohomish County agreed to language in an interlocal agreement that forms the Lake Ballinger/McAleer Creek Watershed Forum.

Strategic Action Plan

The Strategic Action Plan primarily addresses stormwater and surface water flow issues related to the level of Lake Ballinger. Flow issues for the lake related to Hall Creek and McAleer Creek are also included. Secondary objectives include water quality, aquatic habitat and lake and streamside enhancement opportunities. The Strategic Action Plan was funded by a Washington State Department of Ecology appropriation (PDF) allocated by the state legislature to study surface water and groundwater issues that affect Lake Ballinger and McAleer Creek. The Strategic Action Plan was completed in June 2009, and approved by member jurisdictions.


The Watershed Basin and Action Plan promote regional efforts to address stewardship as among the highest environmental priorities in the area. The Mountlake Terrace City Council has directed city staff to continue to collaborate with other cities, Snohomish County, and the State of Washington and the federal government to implement the action plan addressing stewardship issues of Lake Ballinger, McAleer Creek and the streams and lakes that are contained within the greater watershed.
