City Project No. 16007
The City of Plymouth, in cooperation with the Bassett Creek Watershed Management Commission (BCWMC) has been investigating ways to reduce phosphorus and total suspended solids (TSS) levels in Plymouth Creek and ultimately Medicine Lake. Based on water quality monitoring data, Plymouth Creek is impaired for chloride and Escherichia coli and approximately 1500 pounds of phosphorus are in Plymouth Creek as it travels through the Plymouth Creek Playfields contributing to water quality impairments downstream.
A Feasibility Report was completed in 2016 by the BCWMC to analyze and advise on the most cost effective project to repair erosion and improve water quality in Plymouth Creek from Plymouth Creek Park to Annapolis Lane and to begin the process of meeting State mandates associated with current and future TMDLs. The project is expected to include restoration of a vegetative buffer in appropriate areas, root wads, stone toe protection, rip rap, and tree removals.
Development of the Feasibility Report and plans and specifications for the Plymouth Creek Stream Restoration Project included staff from the Parks and Recreation Department as there may be impacts to park users.
Construction on this project began in December 2017 and is anticipated to be substantially complete by July 2018. Tree removals are complete throughout the project. Restoration components including final hydromulch (green) with seed is underway on Reach 3 (see below). Upon completion of restoration in Reach 3, the contractor will move to Reaches 1 and 2 in the park to complete restoration.
