The Municipal Plaza park site will be graded with a generally flat surface that will sheet -flow all stormwater runoff onto the adjacent streets. Stormwater runoff from site C will continue to pond in low lying areas on site C for short periods of time before infiltrating into the ground. A quote for the work contemplated with this case was requested this spring from the project contractor, Northern Lines Contracting. They responded that they were not interested in completing the work. Staff then obtained verbal quotes for this work from other contractors and those quotes generally ranged between $55,000 and $63,000. Following Council approval on July 14th, Staff submitted Requests for Quotes for this work to local contractors and received a total of five (5) quotes on August 5th. A summary of the 5 quotes received is included in the attached resolution. The four lowest quotes were competitive. The highest quote was an outlier at over 3 times higher than the lowest quote. Reshetar Systems of Anoka, Minnesota, submitted the lowest quote in the amount of $60,959.00 in accordance with the Request for Quotes, which falls in the middle of the range or verbal quotes previously received for this work. Notification: Notifications are not required. Observations/Alternatives: Observations: The 8,000 cubic yard sand stockpile is currently situated on the City -owned property north of the new infiltration basins, which is currently marketed for sale. Relocating the sand to the Municipal Plaza park site will allow for more timely development of the Municipal Plaza park, remove the stockpile from the City -owned property marketed for sale, and reduce the amount of fill ultimately needed to develop The COR. It is currently estimated that The COR will require over 300,000 cubic yards of clean fill to fully develop. Alternatives: Motion to adopt Resolution #20-170 accepting quotes and awarding a construction contract to Reshetar Systems in the amount of $60,959 for Municipal Plaza Park Fill, Improvement Project #20-10. Funding Source: As previously discussed, this work was originally proposed to be completed through the COR Infiltration Basin Improvements project, which is being funded by Stormwater funds. Since this work must now be completed outside of that contract, Staff proposes to use a combination of Stormwater funds and Park Dedication funds as identified below. Stormwater funds are proposed to pay for all work required to load and haul the sand to the Municipal Plaza park property (site B), and to establish new turf on the current stockpile site (site A). Park Dedication funds are proposed to pay for all work required to fill the Municipal Plaza park property (site B) including stripping and stockpiling topsoil; unloading, leveling and compacting the sand in one -foot layers; then re -spreading topsoil and establishing turf. NTI's testing services, which are estimated to cost $3,763 per the attached cost estimate, will also be funded from Park Dedication funds. Recommendation: Staff recommends Alternative #1 for reasons noted herein. On June 16, 2020, the Public Works Committee unanimously adopted a motion to recommend City Council approval to solicit quotes to relocate the sand stockpile from the COR Infiltration Basin site to Municipal Plaza park. A draft copy of the meetings are attached for reference. Though the Public Works Committee meeting minutes provide direction to complete the work after Happy Days events are over, based on recent discussions with Council it is Staffs understanding that the Municipal Plaza park
