Summary

These county ordinances apply to unincorporated areas of Blue Earth County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Full Breakdown

Sec. 18-154 of the Blue Earth County Highway Access Management Ordinance requires a written access permit, issued by the county engineer, before construction, alteration, or change of use of any access, whether a driveway or a field entrance, within a county right-of-way. The section lists examples triggering the requirement: a new access onto a county road or county state aid highway, a revised use of or improvement to an existing access, and a development proposal or plat adjacent to an existing or proposed county road or state aid highway; a note under (a) clarifies that splitting a property does not automatically create a right to a new access for contiguous parcels.

Sec. 18-155 requires the written application to be reviewed against the county Transportation Plan, lets the county engineer require a bond to secure compliance, and lets the county remove noncompliant work and require a second permit application, plus removal costs, if built access does not match the permit. Sec. 18-156 allows variances from spacing criteria, with variances under 20 percent of the minimum decided by the county engineer and variances of 20 percent or more requiring county board approval. Sec. 18-153 places administration and enforcement with the county engineer, authorizes removal of any unpermitted access from county right-of-way at the engineer's discretion, doubles the normal application fee for a permit sought after construction has already started, and makes any violation a misdemeanor punishable to the maximum extent allowed by law, with each day of continuing violation a separate offense; the county attorney may also bring civil court action after board authorization.

Violations & Fines

Building, altering, or changing the use of a driveway or field entrance onto a county road without a permit violates Sec. 18-154 and is a misdemeanor under Sec. 18-153(c), punishable to the maximum extent allowed by law with each day of the violation a separate offense. The county engineer may remove an unpermitted access at the county's discretion, and Sec. 18-153(d) doubles the access permit fee for anyone who applies after construction has already begun.

Frequently Asked Questions

Do I need a permit to build a new driveway onto a county road in Blue Earth County?
Yes. Sec. 18-154 requires a written access permit from the county engineer before constructing, altering, or changing the use of any driveway or field entrance within a county right-of-way, including a new access onto a county road or county state aid highway.
What happens if I build my driveway before getting the permit?
Sec. 18-153(d) doubles the normal access permit application fee if the permit is issued after construction has already started. The county engineer can also remove noncompliant or unpermitted work under Sec. 18-153(b), and you would need to reapply and pay removal costs.
Can I get a variance if my driveway doesn't meet the county's spacing rules?
Yes. Sec. 18-156 allows variances from spacing criteria and other standards. The county engineer can grant variances of less than 20 percent of the minimum spacing on a case-by-case basis, while variances of 20 percent or more must be approved by the county board.
