Washington �COunty PUBLIC WORKS Wayne Sandberg, P.E., Director,County Engineer PUBLIC WORKS Frank D.Ticknor, P.E., Deputy Director April 23, 2024 Rachel Juba Community Development Director City of Hugo 14669 Fitzgerald Avenue North Hugo, MN 55038 Dear Rachel, Thank you for the opportunity to review and comment on the draft plan for Liberty Classical Academy, located at the intersection of County State Aid Highway (CSAH) No. 7 (122nd St. N) and County Road (CR) No. 57 (Keller Ave. N). Washington County's Department of Public Works have reviewed the draft plan and offers the following comments: CSAH 7 at this location is currently classified as an "A-Minor Arterial Connector" roadway, while CR 57 is classified as a "Minor Collector." The Washington County 2040 Comprehensive Plan contains access criteria for county roads related to spacing, sightlines, and availability of local road connections. The comprehensive plan requires preserving 75 feet of right-of-way from the centerline along CSAH 7, and 60 feet from centerline along CR 57. The current site plan indicates right-of-way dedications meeting the requirements which will need to be confirmed on final site plans. Access permits will be required for the construction of new driveway connections to county highways. The site plan proposes a new access onto CSAH 7, located approximately 950 feet east of the CSAH 9 (Keystone Ave) and CSAH 7 intersection and a new driveway onto CR 57, north of the existing school building. Washington County's access spacing guideline for Minor Arterials, as adopted through the comprehensive plan, is % mile (1,320 feet) and the CSAH 7 access as shown would fall well short of these guidelines. County staff have worked with the city and developer to maximize this spacing as it relates to the needed septic field, and we appreciate the effort in ensuring as much separation as possible. We also appreciate the important relocation of existing driveways from 122nd Street onto CR 57 with improved spacing from the existing intersection. Proper spacing of access is integral to highway safety and operation, especially where traffic peaks are particularly high. Washington County is amenable to both proposed access locations and strongly supports the relocation of the in-place driveways. Washington County typically requires construction of dedicated left and right turn lanes as a permit condition for streets and driveways projected to carry more than 100 trips per day. The proposed new (relocated) driveway on CR 57 would be anticipated to meet this threshold, however the county is agreeable to reducing this requirement to a right turn lane only at the
