City Council Regular
Consider JPA Amendment for Coon Creek Watershed District Woodcrest Creek Iron Enhanced Sand Filter Project
Sarah Greene, Administrative Assistant II
Council is asked to consider an amendment to the Joint Powers Agreement (JPA) with Coon Creek Watershed District (CCWD) for implementation of the Woodcrest Creek Iron Enhanced Sand Filter Project.
The CCWD and the City share a common interest in improving the treatment of stormwater within the Woodcrest Creek subwatershed. To improve the treatment of stormwater, the parties agree to design, construct, operate and maintain a stormwater pond containing an Iron Enhanced Sand Filter (IESF) on property owned by the City (Woodcrest Park).
The project JPA, originally approved at the February 19, 2019 Council meeting, outlines the scope of work and responsibilities to implement the project, as well as ongoing maintenance to be provided by the City upon completion of the project. The CCWD will be responsible for performance monitoring of the completed project.
While processing the Board of Water and Soil Resources (BWSR) grant work plans, the CCWD encountered reporting complexities due to having multiple grant funding sources. In order to simplify, the CCWD recommends offsetting the Watershed Based Funding grant money with District funds. This would maintain the same project budget without impacting the City's contribution, and would reduce the noncompliance liability. The only change needed to make this effective is to clarify the language in the JPA per the attached amendment.
The City's financial contribution to this project is $217,000, which was included in the 2019 stormwater drainage fund budget. The total cost of the project is estimated to be $889,000. Other funding for the project will be provided by the CCWD and Clean Water Funds. The Cities of Blaine and Fridley both have IESFs installed for water quality benefits as part of their stormwater drainage systems. Discussions with staff at the City of Blaine indicate maintenance costs for their IESF to be around $1,000 to $1,500 per year.
The project will take place adjacent to a portion of Woodcrest Creek that runs through Woodcrest Park. The project is within an existing City pond located on the west side of Woodcrest Drive. The goal of the project is to reduce total phosphorus and E. coli loading into Woodcrest Creek, which drains to Coon Creek (an MPCA impaired stream).
The CCWD and the City held a public open house on May 30, 2019 to notify nearby properties of the proposed work. The tentative construction timeline includes award of contract in September, with work to commence shortly thereafter. Staff will be kept apprised of the project status throughout construction, which is expected to be completed by March, 2020.
Staff recommends Council approve the Amendment to the Joint Powers Agreement with Coon Creek Watershed District for the implementation of the Woodcrest Creek Iron Enhanced Sand Filter Project.
Funding for the City's cost of this project is included in the 2019 Stormwater Utility Fund (640).
