26 The Mill and Overlay projects are proposed to be financed through our street infrastructure 27 funds and MSA funds. After receiving bids for these projects, we will request that the City 28 Council award the bid to the lowest responsible bidder. 2s 30 Reconstruction: We do not anticipate any total reconstruction projects for 2014. 31 32 Sanitary Sewer lining and replacement, watermain replacement: The majority of the 33 city's sanitary sewer mains were constructed in the late 1950's and early 1960's, utilizing 34 clay the pipe. Overtime the joint materials have failed allowing root intrusion. The pipe is 35 also susceptible to cracking and construction damage. The 2013 Capital Improvement Plan 36 recommends funding for a sanitary sewer main lining program to extend the life of our 37 sanitary sewers by 50 years or more. This technology essentially installs a new resin pipe 38 inside the old clay tile sewer main without digging up city streets, which results in minimal 39 disruption to residents during construction. The liner pipe is inserted into the main through 40 existing manholes and cured in place with a heat process. Any given segment is usually 41 completed in one working day. Service line connections are reopened using a robotic cutter 42 and remote cameras. During the process, existing flows are bypassed using pumps. This 43 technology has been proven over the past 20 years, and costs have become competitive with 44 open cut replacement. The City started doing this type of renovation on and annual basis in 45 2006 and will have an annual project for the foreseeable future to replace our aging sewer 46 infrastructure. This technology also prevents infiltration of groundwater into the system and 47 can be credited toward current and future inflow/ infiltration surcharge. The location of this 48 work varies and is spread throughout the City based on system priority. 49 We are also evaluating sanitary and storm sewer replacement needs in our pavement 50 replacement areas as well as utility infrastructure needs in County and State project areas. 51 Those replacements are being identified from recent utility inspections and adjustments to 52 the plan will be communicated to the Council at a later date. 53 2. Storm Sewer system improvements: Another extreme rain event occurred this summer on 54 June 21, 2013, that caused localized flooding again in several areas of the City. Staff 55 continues to to analyze the existing drainage systems and localized flooding issues and is 56 identifying mitigation projects. Staff is now working on developing a 2014 drainage 57 improvement project to alleviate some of these flooding concerns. 58 3. Seal Coat: Pavement maintenance policies support an annual seal coat program of 59 approximately 14 -15 miles of city streets each year. This consists of applying athin film of 60 bituminous oil and covering it with fine aggregate. These treatments have proven to add a 61 minimum of 10 years to the life of the pavement. The 2014 program is constrained due to 62 budget limitations. 63 4. Pathways : Staff is developing the plans for the sidewalk project on County Road B -2 64 from Lexington Ave. to Rice St. and adjacent legs on Victoria St. This project will be funded 65 by the Park Renewal Bonds and stormwater funds for the drainage improvements. Staff is 66 working closely with the Park Renewal Project Team on this project. We are also proposing 67 to replace the pavements on pathway segments in Langton Lake Park and Central Park. 68 Parking lots at the Dale Street Soccer fields, Oasis Park, and Autumn Grove Park will be 69 replaced or rehabilitated as part of this program or the Park Renewal Program. These projects 70 will be completed in summer 2014. Page 2 of 3
