The original developer walked <br />away from RTC 9 th Addition before it was complete. CentraHomes is in the process of completing construction of <br />this private residential development. <br />Based on current stormwater management and wellhead protection standards, infiltration of stormwater is <br />prohibited in Wellhead Protection Areas, which encompasses all of RTC 9th Addition, including the two <br />stormwater ponds. Staff proposes to install a geosynthetic clay liner within both ponds to prevent infiltration and <br />protect the source aquifer for the City's municipal water supply system. <br />While CentraHomes was developing their plans, Staff asked what their costs would be to line the ponds in hopes of <br />executing a reimbursement agreement with CentraHomes to complete all work at the same time. In order for <br />CentraHomes to obtain quotes, they needed plans for the pond lining improvements. City Staff developed plans and <br />provided them to CentraHomes. Unfortunately, their quotes were significantly higher than the engineer's estimate <br />based on the plans prepared in-house. Attached is a copy of the plans prepared by City Staff. <br />On September 24th, the City Council approved the plans prepared by City Staff and authorized advertising for bids <br />to construct the project. <br />Notification: <br />Bids were advertised in the Anoka Union Herald and in Finance and Commerce on October 4, 2019. Bids were also <br />advertised using QuestCDN via the City's website. <br />Observations/Alternatives: <br />
