Title:
Adopt Resolution #19-233 Approving Plans and Specifications and Authorizing Advertisements for Bids for Improvement Project #19-06, Ramsey Town Center 9th Addition Pond Lining Improvements
Purpose/Background:
Purpose:
The purpose of this case is to adopt Resolution #19-233 approving plans and specifications and authorizing advertisements for bids for Improvement Project #19-06, Ramsey Town Center 9th Addition Pond Lining Improvements.
Background:
Two un-lined stormwater ponds were constructed as part of the Ramsey Town Center (RTC) 9th Addition in the early 2000's, allowing infiltration of stormwater runoff into the underlying soils. The original developer walked away from RTC 9th Addition before it was complete. CentraHomes is now completing this private residential development.
Based on current stormwater management and wellhead protection standards, infiltration of stormwater is prohibited in Wellhead Protection Areas, which encompasses all of RTC 9th Addition, including the two ponds. Staff is therefore proposing to line the two ponds in RTC 9th Addition to prevent infiltration.
While CentraHomes was developing their plans, Staff asked what their costs would be to line the ponds in hopes of executing a reimbursement agreement with them to complete the work all at one time. In order for CentraHomes to obtain quotes, they needed plans for the pond lining improvements. City Staff developed plans and provided them to CentraHomes. Unfortunately, their quotes were significantly higher than the engineer’s estimate based on the plans prepared in-house. Attached is a copy of the plans prepared by City Staff.
Staff is requesting authorization to bid the project this fall/winter in anticipation of receiving good bids based on the time of year and on bidding more than one drainage improvement project at the same time.
