This project will generate approximately 35,000 cubic yards of soil that will need to be exported. Based on the need for fill within two other areas of The COR, the plans incorporate provisions for the Contractor to place the excess fill in those areas after installing erosion control measures (silt fence) and stripping the existing topsoil to expose the underlying granular material. This base material will be tested and compacted, and the imported fill will be placed in specified lifts that will be compacted and documented. The area south of Sunwood Drive and east of Zeolite Street was identified as one of the sites for the excess fill. This site will take approximately 6,000 cubic yards. Bringing this site to grade will accomplish two things. It will address a concern raised by the Minnesota Department of Health about the area around the municipal well being depressed and holding water. It will also make the site more marketable. The remainder of the fill will be placed in the Municipal Plaza recreational area of The COR north of Sunwood Drive and west of Center Street. Attached are sheets 11 to 14 of the draft plans. Staff will present the plans in more detail during the meeting. This case was reviewed by the Public Works Committee on April 16, 2019, at which time the Committee recommended CIty Council approval of plans and specifications and authorization to advertise for bids. Funding Source: The estimated cost for the improvements is $1,200,000. The City has collected infiltration mitigation funds from all developments that have occurred in The COR since 2015. These funds will pay approximately 1/4 of the cost of the project. The City will pay the remainder of the project now using stormwater utility funds. These costs will be reimbursed as future development occurs. Recommendation: Staff recommends the City Council adopt resolution 19-115 approving Plans and Specifications and authorizing Advertisements for Bids for The COR Infiltration Basin Improvements, Improvement Project #18-09. Action: Motion to adopt resolution #19-115 approving Plans and Specifications and authorizing Advertisements for Bids for The COR Infilrtration Basin Improvements, Improvement Project #18-09.
