Spot curb replacements are also done at this time but only where there are significant structural issues with the in-place curb or significant settling. The Mill and Overlay projects are proposed to be financed through our street infrastructure funds and Municipal State Aid funds. After receiving bids for these projects, we will request that the City Council award the bid to the lowest responsible bidder. The estimated cost of the Mill and Overlay portion of the PMP Project is $1.3 million. As part of the Pavement Management Program staff will evaluate the underlying water mains and sanitary sewer lines in the street right-of-way in these areas. We will take advantage of the repaving of the roadways to repair/replace these utilities and deemed appropriate. These repairs and replacements will be funded from the water and/or sanitary sewer utility funds. Reconstruction: We are proposing to reconstruct Victoria Ave from Larpenteur Ave to County Road B in 2015. Reconstruction of a roadway involves complete removal of the in place pavement, establishing a solid sub -base for the new pavement surface, and then repaving the roadway with a City standard section. The roadway section will also be evaluated for new curb and gutter where deemed necessary and storm water improvements. The estimated cost to reconstruct the roadway is approximately $1.5 million which includes storm water improvements. This will be funded with a mix of Municipal State Aid funds, special assessments to benefiting properties and storm water utility funds. We are also recommending the construction of a new pathway along Victoria Street from Larpenteur Ave to County Road B2. It is estimated the cost of the pathway will be approximately $400,000. The pathway segment within the reconstruct area will be funded with Municipal State Aid funds while the segment north of County Road B will be funded with Park Renewal funds. 2. Sanitary Sewer and Water Main Infrastructure: The majority of the city's sanitary sewer mains were constructed in the late 1950's and early 1960's, utilizing clay tile pipe. Over time the joint materials have failed allowing root intrusion. The pipe is also susceptible to cracking and construction damage. The 2015 Capital Improvement Plan recommends funding for a sanitary sewer main lining program to extend the life of our sanitary sewers by 50 years or more. This technology essentially installs a new resin pipe inside the old clay tile sewer main without digging up city streets, which results in minimal disruption to residents during construction. The liner pipe is inserted into the main through existing manholes and cured in place with a heat process. Any given segment is usually completed in one working day. Service line connections are reopened using a robotic cutter and remote cameras. During the process, existing flows are bypassed using pumps. This technology has been proven over the past 20 years, and costs have become competitive with open cut replacement. The City started doing sewer lining on an annual basis in 2006 and will have an annual project for the foreseeable future to replace our aging sewer infrastructure. This technology also prevents infiltration of groundwater into the system and can be credited toward current and future inflow/infiltration surcharges which are mandated by the Metropolitan Council. The location of this work varies and is spread throughout the City based on system priority. City staff is also planning on rehabilitating the Wagner sanitary sewer life station at a cost of about $130,000.
