This project will reduce nutrient loadings to Sand Creek from the neighborhoods which are the greatest contributors. Project activities include the installation of a new stormwater pond and a network of 10 strategically-placed curb-cut rain gardens.
Varney Lake is owned and maintained by the City of white Bear Lake as part of its stormwater collection system. The City will excavate approximately 10,000 cubic yards of polycyclic aromatic hydrocarbons (PAH) contaminated sediment from Varney Lake (which is located in a residential portion of the City) and manage the sediments on site by encapsulating the sediment in a berm covered with clean top soil. The encapsulated sediment will be managed as a solid waste in what the MPCA refers to as a limited use solid waste landfill (Facility).
This project will remove accumulated sediment from two Stormwater Treatment Ponds in Circle Pines that were constructed in the 1970’s. Recent testing of the sediments indicates that Tier 2 and 3 PAH compounds were found in the sediment. The most recent estimate for the volume of material that will be removed is 2,400 Cubic Yards.
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
