Adopt Resolution #19-132  #19-165 Accepting Bids and Awarding Contract for Improvement Project #18-09, COR Infiltration Basin Improvements

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 CIty 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 April 9, 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.

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 fill will also be placed in the Municipal Plaza recreational area of The COR north of Sunwood Drive and west of Center Street.  Excess fill will be stockpiled north of the project on City owned land for use elswhere in the COR.

Alternatives:
Alternative #1 - Motion to adopt Resolution #19-132 #19-165 accepting bids and awarding contract for construction for Improvement Project # 18-09 COR Infiltration Basin Improvments to __________ in the amount of __________.

Alternative #2 - Motion to deny adoption of Resolution #19-132 at this time.

Project Costs
Construction and total project costs are based on the lowest responsible bid recieved for Northern Lines Contracting, Inc of Bloomington, Minnesota, are as follows:
 

	Total Bid
Construction Costs	$607,136.11
Project Costs	$767,777.42

Project costs include 23% indirect costs for administrative (6%), engineering (15%), finance (1%) and legal(1%) costs.

Attached is a proposal from Bolton & Menk, Inc. for construction staking services using 2019 hourly rates.  With the recent retirement of the senior engineering technician, Staff no longer has the ability to stake construction so consultants will need to provide this service on all future public improvement projects.  This cost is included under indirect costs for engineering.

Proect Funding
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.

Staff recomments Alternative #1. Construction of the project in 2019 will fullfill the City obligation to the LRRWMO for providing infiltration for projects in the COR.

Motion to adopt Resolution #19-132 #19-165 accepting bids and awarding a contract for construction of Improvement Project #18-09, COR Infiiltration Basin Improvements to _______ in the amount of  $____________.
