This project will be eligible for construction cost reimbursement through the <br />Metropolitan Council's Inflow & Infiltration (I & I) grant program. The City has traditionally <br />planned CIPP lining projects on a 2-year cycle or adjusted them to align with the Met Council I <br />& I program. <br />Through the Public Works' sanitary sewer maintenance program, inspections identified the <br />proposed segments of sewer needing repairs due to significant cracks or voids, root intrusion and <br />also aging clay pipe (VCP) that indicated a need for rehabilitation. Through the CIPP process, I <br />& I is eliminated at the joints and cracks of the existing pipe and the new lining is known to <br />extend the life of the pipe by at least 50-years. The location of the project area is within the Glen <br />Arden neighborhood and is identified on the map within Attachment B. <br />City staff has contacted engineering consultant, TKDA, to provide professional services to <br />administer this project through design, specifications development, bidding and construction <br />administration. TKDA has recently completed projects for the City including the 2024 CIPP <br />Lining Project, Arden Oaks Street Improvements Project, the Trunk Watermain Assessment <br />Page 1 of 2 <br />
