Project Number: PL-7
In August 2019, the BCWMC approved a proposal by the Commission's Engineers to develop a feasibility study for this project in conjunction with the Mt. Olivet Stream Restoration Project, also in Plymouth. A public open house on both projects was held in February 2020 to answer questions and get feedback from residents and other stakeholders. The feasibility study was approved in May 2020 with intent to implement Alternatives 3 and 6. A public hearing was held September 17, 2020; there was no public input. The project was officially ordered by resolution on that date and an agreement with the city of Plymouth to design and construct the project was approved. Work is underway on the chloride reduction portion of the project through facilitated discussions and review of chloride data by a group of technical stakeholders. 60% project designs for the drainage improvement project will be presented to the Commission at their June 17, 2021 meeting.
The total cost of this project is estimated at $485,000 including feasibility study, design, construction, chloride reduction practices, and administration. CIP funds for projects like this are collected through an ad valorum tax levied by Hennepin County on all Bassett Creek Watershed residents.
This project will stabilize slopes and make other drainage and stormwater management improvements along an intermittent stream reach beginning at 18th Avenue North and continuing downstream 1,100 feet to just northwest of the intersection of County Road 6 and Niagara Lane North. Stabilizing banks will reduce sediment and nutrients reaching Parkers Lake and will improve habitat along the drainage way. Expected pollutant reduction to the lake is 20.1 pounds/year of total phosphorus.
Additionally, this project includes approximately $300,000 for chloride management and reduction practices or programs in the area north of the lake. Parkers Lake is considered impaired due to high chloride (salt) concentrations which is toxic to aquatic life and disrupts the natural lake processes. Water monitoring indicates that most of the chloride pollution is from winter deicers flowing from the area north of the lake. The BCWMC and the city of Plymouth will work with landowners and businesses in this area to implement winter maintenance practices and programs that use less salt.
A neighborhood meeting and public open house with a presentation of project design plans will be held Wednesday, June 16th starting at 5:00 p.m. via Zoom. Register at: https://us02web.zoom.us/meeting/register/tZUtceCor....
