APPROVAL OF SUPPLEMENTAL AGREEMENT WITH ROSTI CONSTRUCTION FOR
THE EMBANKMENT REPAIR ALONG THE KENRICK AVENUE TRAIL
Proposed Action
Staff recommends adoption of the following motion: Move to approve a supplemental
agreement for the repair of the trail embankment along the Kenrick Avenue Trail.
Overview
At the September 15, 2014 City Council Work Session Don Sterna from WSB presented
options for the repair of the trail embankment north of Marek's Towing which eroded twice,
once following the record rainfalls in the spring after which it was reconstructed and again
following the heavy rains Father's Day weekend. It was originally estimated that the preferred
option, flattening of the slope to a 2:1 by construction of a Prefabricated Modular Block Wall,
seeding, blanketing and other erosion measures would cost $63,951. Based upon
negotiations with staff, the cost to perform the described work will be $53,200.
Primary Issues to Consider
Is the embankment repair necessary? Yes, continued erosion could affect the
integrity of the trail and Kenrick Ave.
