33 A new pathway, Marion Street Phase 2, will be constructed on the west side of Marion Street 34 from Larpenteur Avenue to the cul-de-sac. The new pathway will connect to the first phase, 35 which was completed this past fall, in conjunction with the Enclave development and make a 36 connection to Unity Park. This will complete the pathway envisioned in the Rice-Larpenteur 37 Visioning Plan. 38 Pathways in Central Park east of Victoria Street and on Larpenteur Avenue between Gaultier 39 Street and Rice Street will be resurfaced. 40 The parking lot at the Nature Center will be resurfaced. 41 Pedestrian Flashers: The existing pedestrian flasher at Lexington Avenue and Central 42 Park/Oakcrest Avenue will be upgraded to a rectangular rapid flashing beacon (RRFB) system as 43 part of the Lexington Avenue Resurfacing Project done by Ramsey County. A similar system 44 was installed last year at Victoria Street and Central Park. 45 Ramsey County will also be installing a RRFB system on Lexington Avenue near Josephine 46 Park/Dairy Queen as part of the Lexington Avenue Resurfacing Project. 47 3. Utility Infrastructure: 48 Sanitary Sewer Lining: The majority of the city’s sanitary sewer mains were constructed in the 49 late 1950’s and early 1960’s, utilizing clay tile pipe and reinforced concrete pipe. Over time, the 50 joint materials have failed allowing root intrusion. The pipe is also susceptible to cracking and 51 construction damage. The 2022 Capital Improvement Plan recommends funding for a sanitary 52 sewer main lining program to extend the life of our sanitary sewers by 50 years or more. This 53 technology essentially installs a new resin pipe inside the old clay tile sewer main without 54 digging up city streets, which results in minimal disruption to residents during construction. The 55 liner pipe is inserted into the main through existing manholes and cured in place with a heat 56 process. Any given segment is usually completed in one working day. Service line connections 57 are reopened using a robotic cutter and remote cameras. During the process, existing flows are 58 bypassed using pumps. This technology has been proven over the past 20 years, and costs have 59 become competitive with open cut replacement. The City started doing this type of renovation 60 on an annual basis in 2006 and will have an annual project for the foreseeable future to replace 61 our aging sewer infrastructure. This technology also reduces infiltration of groundwater into the 62 system and can be credited toward current and future inflow/infiltration surcharges which are 63 mandated by the Metropolitan Council. In 2022, approximately 5.6 miles of sanitary pipe are 64 scheduled to be lined. The location of this work varies and is spread throughout the city, based 65 on system priority. 66 Pipe Replacements/Repairs: Staff evaluates sanitary and water main replacement needs in our 67 pavement replacement areas as well as utility infrastructure needs in County and State project 68 areas. To date, City staff has identified sewer replacements in the following locations: 69 County Road B & 200 feet east of Dale Street 70 To date, City staff has identified improvements to the water distribution system in the following 71 locations: 72 Lexington Avenue, RR Tracks to Woodhill Avenue 73 o This section is proposed to be replaced due to a high water break history.
