CC Regular Session Meeting Date: 06/11/2019 Submitted For: Len Linton, Engineering/Public Works By: Len Linton, Engineering/Public Works Information 7. 3. Title: Adopt Resolution 1119-132 #19-165 Accepting Bids and Awarding Contract for Improvement Project #18-09, COR Infiltration Basin Improvements Purpose/Background: Purpose The purpose of this case is to adopt Resolution #19-132 accepting bids and awarding a contract for construction of Improvement Project #18-09, COR Infiltration basin Improvements. Background Attached is a copy of the plans prepared by Clty Staff for Improvement Project #18-09 COR Infiltration Basin Improvments, which proposes to construct a Regional Infiltration basin in the northwest quadrant of Ramsey Boulevard and the BNSF Right of Way. The plans show the location and general scope of the work.. The City made the decision to place their municipal wells in the western part of the City where development was expected to happen in the mid 1990's. The area around the wells was selected as the site of Ramsey Town Center (RTC) in the early 2000's. The state required development of a wellhead protection plan for the wells in the mid 2000's. The City acquired the foreclosed RTC properties in 2009 and began marketing the properties as The COR. The City is part of the Lower Rum River Watershed Management Organization (LRRWMO), which is tasked with maintaining water quality through regulating stormwater discharges. The LRRWMO Third Generation Plan was adopted in 2012, and must be updated every 10 years just like the City Comprehensive Plan. The Third Generation plan required infiltration of the first one (1) inch of runoff from all impervious surfaces (roofs and paving) on new projects. The infiltration guidelines discourage or prohibit infiltration in wellhead protection areas. The Third Generation Plan has a provision that projects can pay into an infiltration mitigation fund if they cannot infiltrate on site. Most of The COR area to be developed is in the area where infiltration is not permitted. All projects developed in the COR since 2015 have paid into the infiltration mitigation fund. LRRWMO permits were approved for these projects with the condition that the City develop an infiltration basin in an area where infiltration is permitted. The City was first required to have the infiltration basin in place by July 1, 2018. The LRRWMO Board later extended this requirement to September 30, 2019. The City Council approved preparation of plans and specifications for the COR Infiltration Basin Improvements on April9, 2018. The City Council approved the plans and authorized advertisement for bids on May 14, 2019. Construction of the improvements is estimated to take 60 to 75 days, depending on weather.
