reclaimed and replaced due to the condition of the roadway. 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 (MSA) funds. After receiving bids for these projects, we will request that the City Council award the bid to the lowest responsible bidder. 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. These repairs and replacements will be funded from the water and/or sanitary sewer utility funds. Reconstruction: No roads are proposed to be reconstructed in 2016. Seal Coat: As in 2015, the City will not be doing a seal coat program due to pavement delamination issues. The budget for seal coating will be used to mill and overlay additional roads as part of the PMP project. 2. Pathways: Staff is working with Ramsey County and Community Development to develop a sidewalk on the north side of Larpenteur Ave from Mackubin St to Galtier St. This would connect to sidewalk or pathway on either end of the project and connect a missing gap. County State Aid funding and Community Development Block Grant (CDBG) funding is the proposed funding source for a portion of the sidewalk improvements on Larpenteur Avenue. The attached project map also shows several segments of existing trail or sidewalk that will be repaved/replaced in 2016. 3. Utilitv Infrastructure: Sanitary Sewer Lining: The majority of the city's sanitary sewer mains were constructed in the late 1950's and early 1960's, utilizing clay tile pipe and reinforced concrete pipe. Over time the joint materials have failed allowing root intrusion. The pipe is also susceptible to cracking and construction damage. The 2016 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 this type of renovation 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 reduces infiltration of groundwater into the system and can be credited toward current and future inflow/ infiltration surcharges which are mandated by the Metropolitan Council. In 2016 approximately 4.7 miles of sanitary pipe are schedule to be lined. The location of this work varies and is spread throughout the City based on system priority. Pipe Replacements/Repairs: We are also evaluating sanitary and water main replacement needs in our pavement replacement areas as well as utility infrastructure needs in County and
