Statement of Problems, Opportunities, and Existing Conditions This project will extend clean drinking water to 62 homes located in and adjacent to the Parkview Estates, Cardinal Ridge, and Cardinal View subdivisions in the City of Lake Elmo by extending the municipal water system into the neighborhood prior to reconstructing the neighborhood streets as scheduled for improvement in 2022 in the City’s Capital Improvement Plan. The project extends an 8‐inch public watermain from Inwood Avenue into and throughout the Parkview Estates neighborhood along Ivory Avenue, Ivory Court and 16th Street. The watermain then extends into the Cardinal Ridge neighborhood along 16th Street and then along Ivy Avenue. A watermain is also extended along 15th Street , making a looped connection to the Inwood Avenue trunk watermain while also extending the public watermain to 15th Street Court to serve the properties within the Cardinal View neighborhood. An additional six properties along 15th Street would also be able to connect to City watermain. Individual water service stubs will be installed to the edge of right‐of‐way at each of the 62 residential properties. Following the installation of the public watermain improvements, the public streets, including Ivory Avenue, Ivory Court, 16th Street, Ivy Avenue, 15th Street and 15th Street Court will be improved. The properties reside in an area where per- and polyfluoroalkyl substances (PFAS) contamination exceeds Health Based Values (HBVs) and well advisories have been issued. The project is consistent with the long-term drinking water supply plan to address PFAS contamination to drinking water supplies in the East Metro area. Individual water services will be stubbed from the main line for each of the 62 residential properties. The project will include grant funding and administrative processes for ensuring each property completes the private service connection from the service stub to each home, including water meter installation, sealing of the private well including a well at Pebble Park, removal of any existing granular activated carbon (GAC) filters, and all permitting and connection fees. The City intends to directly implement the public improvement portion of the project for the water main components that will remain owned and operated by the City and will require property owners to contract directly for the work to be completed on their individual properties. The private property work will be funded on a reimbursement basis . The City will distribute materials, provided by the MPCA, regarding individual/residential water service connections and well sealing to all residents impacted by this project. In accordance with the City's standard Capital Improvement Program process, a feasibility study and project design will be completed to ready the project for 2022 construction. Bids will be received in early 2022 with construction to commence in May 2022. The water main will be tested, operational and ready for connection to the in dividual properties in late 2022. No environmental review is required to implement this project. The project will require the following permits:* • Minnesota Department of Health Watermain Extension Permit • Washington County Right-of-Way Permit • Valley Branch Watershed District Permit • MPCA National Pollutant Discharge Elimination System Construction Permit * The City will need to demonstrate expenses related to these items are attributable to actions necessary to address PFAS impacts. 3. Measurable Outcomes The City will report at least quarterly to the MPCA regarding progress of the project. The City will also report to the MPCA as part of the quarterly report the itemized costs incurred for that quarter for reimbursement by the MPCA. Monthly reimbursement requests can be provided as determined by the City. DocuSign Envelope ID: 3B0D0679-5F9B-4A3F-B21E-0CBD1954D6B1
