Mt. Vernon Waterfront Revitalization Phase II
Located along the banks of the Skagit River, sixty miles north of Seattle, is the city of Mount Vernon, Washington.
This community, which is known for its annual Tulip Festival Street Fair and was once deemed the “#1 Best Small City in America,” has been plagued by immense flooding. The devastating effects of this flooding have limited the city’s ability to promote its unique tourist opportunities.
In order to alleviate the flooding issue, the city developed a multi-year plan. The plan included the purchase of a mobile flood wall that could be installed during events.
This was utilized as a stop-gap measure while designers worked on developing a long-term solution. The long-term solution decided upon was the $27.3 million Private-Public Partnership Waterfront Revitalization Plan, which was broken down into multiple phases.
Phase I was completed in October 2010, and included a permanent floodwall fron Division Street Bridge to Lions Park. This phase provided the necessary protection for the downtown districts but did not address the city’s revitalization needs.
In 2013, Phase II brought Mount Vernon a 1,650-foot riverwalk, a trail to connect all existing trail systems, and a 30,000 square foot public riverfront park. Designed to be a focal point of the revitalization efforts, this park includes gathering areas, an open area for the town farmer’s market, and a beautiful overlook of the river.
Shade trees were also to be incorporated in the park, so designers planned to utilize a subsurface plastic support system. This system was designed to support the weight of the surface and any loads applied to the surface, while providing void space filled with uncompacted soil. This soil promotes root growth and tree health.
When the specified product proved to be costly and caused for a lengthening of the project timeline, the project contractor reached out to Brentwood.
Installed in the summer of 2014, Brentwood’s StormTank® Module Urban Root System met all of the contractor’s requests, while also meeting the design requirements of the project engineer. The StormTank system supports surface loads while creating a void space for uncompacted soil, allowing for unobstructed development and improved tree health. With the help of this system, the park will allow Mount Vernon to get back to its roots and reintroduce itself as a tourist hub.
