Next meeting:

November 17, 2020 at 2 PM - Virtual Meeting (Zoom) due to COVID-19 Pandemic.

What is the purpose of the forum?

The cities of Edmonds, Lake Forest Park, Mountlake Terrace, and Snohomish County coordinate efforts under an interlocal agreement to address problems relating to water quality and storm water runoff that can contribute to flooding and property damage in the Lake Ballinger/McAleer Creek Watershed.

How can I be involved?

Residents are encouraged to join forum meetings that are held quarterly!  Residents can also get involved in a number of way by volunteering to remove invasive species, collect data, encourage behavior changes, and more.  The forum is excited to engage with anyone that would like to address issues in our watershed. 

When does the forum meet?

The forum meets quarterly, or once every three months.  The date, time, and location will be posted at the top of this page.  If you have questions or suggestions please reach out to Laura Reed

What has been accomplished so far?

In 2008, a Lake Ballinger lake level study was completed.  In 2009, a Strategic Action Plan was developed and approved by the forum's five local jurisdictions in the watershed. The Strategic Action Plan prompted the development of a Capital Improvement Program for the watershed in 2010.  In 2013 and 2014, the City of Mountlake Terrace replaced three culverts on McAleer Creek and one culvert on Hall Creek.  Lake Forest Park completed significant flood abatement projects between 2012 and 2017. Since 2017, aquatic invasive species surveys and management efforts have been conducted on Lake Ballinger with improvement observed in 2020. 

What are the forum's goals for the future?

The City of Edmonds will construct a regional stormwater infiltration facility in Mathay-Ballinger Park which will improve the water quality reaching Lake Ballinger from Edmonds.

The City of Mountlake Terrace will improve habitat quality for birds, reptiles, amphibians, and some mammals along Hall Creek through the Ballinger Park Hall Creek Restoration project.  This project will also develop a park space for passive enjoyment, increase stream channel capacity, improve water quality in Lake Ballinger, and provide educational signage for visitors. 

The Cities of Edmonds and Mountlake Terrace will continue improving habitat and water quality in Lake Ballinger by managing aquatic invasive plant species.  A herbicide treatment was carried out in 2019, volunteers have removed some invasive plants, and a bottom barrier installation is being completed in 2020.  There has already been a notable increase in native aquatic vegetation in 2020. 

The forum plans to conduct a habitat inventory in order to gain an understanding of baseline habitat and biological use of Hall Creek, Lake Ballinger, and McAleer Creek. 

The Cities of Mountlake Terrace and Edmonds plan to develop a calibrated hydraulic and hydrologic model for Lake Ballinger.  This model will determine flood impacts under various scenarios during large storm events.  This will give accurate guidance for development and redevelopment within the affected floodplain. 

The City of Lake Forest Park plans to enhance and replace a culvert at Perkins Way on McAleer Creek in order to reduce localized flooding. 

What is the history of the forum?

In 1972, 34 lakes in the region were sampled and Lake Ballinger was discovered to have the worst water quality of those selected.  Lake Ballinger flooded in 1997 and 2004, the latter of which prompted conversations between the Cities of Edmonds and Mountlake Terrace to develop and implement solutions. 

In 2006, the Cities of 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 stormwater flow.

In December 2007, the Cities of Edmonds, Lake Forest Park, Lynwood, Mountlake Terrace, and Shoreline along with Snohomish County began discussions related to support of a joint Watershed Basin Action Plan. After adoption of resolutions by each of the 5 cities and Snohomish County, an interlocal agreement was drafted and adopted by the 6 jurisdictions to develop a Strategic Action Plan to outline specific goals to protect the Watershed. The Action Plan was completed in June 2009.

The forum has continued to meet and address water quality and flooding in the watershed.
