19-40: Pleasure Creek Iron Enhanced Sand Filter/Biochar

Project Description

Pleasure Creek Iron Enhanced Sand Filter/Biochar (IESF/B) project on the south side of Pleasure Creek park at 10002 Pleasure Creek Parkway East is underway. A message center has been installed onsite with project details and contact information.

What is an IESF/B?

An IESF/B is a filtration practice that incorporates filtration media mixed with iron and bio-char. The iron removes phosphorus which is the chemical that supports rapid algal growth and reproduction. The bio-char removed E.coli which is bacteria found in animal waste. Both phosphorus and E.coli have been identified as water quality problems in the Pleasure Creek watershed. 

What will generally be done on the project?

  • Trail closure signs will be installed at the site.
  • Erosion control devices will be installed around the perimeter of the project.
  • The upper one foot of existing soil (and all topsoil) will be removed.

Tree Removals and Vegetation Plan

The project will necessitate removal of three trees with the city property to allow for construction of the project. No trees on private property will be removed. Once the project is completed, a variety of native grasses and shrubs will be planted around the perimeter of the filter.

Funding Source

This project is being funded through a grant from the Minnesota Clean Water Fund Watershed Based Funding, the Coon Creek Watershed District, and the City of Blaine stormwater utility fees.

Project Schedule

The bid award took place on September 23, 2019, at the Coon Creek Watershed District Board meeting. The contractor began construction on September 30 and the project will be completed by March 2020. Please note that this schedule is tentative and could vary slightly depending on weather or other scheduling delays.
