BACKGROUND: On May 21, 2024, the City Council authorized the preparation of a feasibility report in response to a petition from the Stillwater Area School District, requesting the connection to City water and sanitary sewer to the Oak-Land Middle School, and connection to City sewer to the new Lake Elmo Elementary School.
