BACKGROUND, PROPOSAL DETAILS/ANALYSIS: As part of Washington County’s Capital Improvement Program, the County has reconstructed County State Aid Highway 13 (Olson Lake Trail/Ideal Avenue) in the Cities of Lake Elmo and Oakdale, with the construction completed in 2018. The improvements included the extension of sanitary sewer (system to be owned and maintained by the City of Oakdale), a bituminous trail along the west side of the roadway, and street and drainage improvements, including a storm water pond located within Lake Elmo City limits. The purpose for the Cooperative Maintenance Agreement is to outline the respective ownership and maintenance responsibilities for the new improvements between Washington County and the Cities of Lake Elmo and Oakdale. Key elements of the agreement are as follows: • The County shall own and maintain, without any expense to the City, all street, drainage and storm sewer improvements located within County right-of-way, including pavement maintenance, curb and gutter, cross walk and pavement markings, signage, retaining walls and fencing, and guardrails. • The County will mow the corridor boulevards a maximum of twice per year. • The City shall own and maintain, without any cost or expense to the County, the pavement, curb and gutter, pavement markings, and street signs located within City right-of-way and at all City street approaches to CSAH 13 (Olson Lake Trail/Ideal Avenue). • The County shall own and maintain the infiltration basin/pretreatment basin constructed for the project, however, the City agrees to participate in 3% of the cost incurred by the County to perform major maintenance for the infiltration basin/pretreatment basin. Major maintenance includes removal of sediment from the basin to restore the basin to its original volume, restoring the infiltration capacity of underlying soils and/or infiltration media, and stabilizing any surface and side slope disturbances, inlet and outlet pipe, structure, and apron repair and/or replacement. • The trail and pedestrian ramps located on the west side of CSAH 13 and within the County right- of-way will be maintained by the County and the City of Oakdale as outlined in Washington County Agreement No. 11537 with the City of Oakdale. • All maintenance required to be performed by this agreement by the Parties shall be performed in a manner which shall be at the sole discretion of the party so obligated. RECOMMENDATION: Staff is recommending that the City Council approve, as part of the Consent Agenda, the Cooperative Agreement with Washington County for the Maintenance of the CSAH13 (Olson Lake Trail/Ideal Avenue) Improvements. If removed from the Consent Agenda, the recommended motion for the action is as follows: “Move to approve Resolution No. 2018-106 approving Cooperative Maintenance Agreement 11536 for the CSAH13 (Olson Lake Trail/Ideal Avenue) Improvements.” ATTACHMENTS: 1.
