Lighting Regulations in Dundas, Minnesota: Balancing Historical Character with Modern Illumination Needs

Introduction

Nestled along the scenic Cannon River, Dundas, Minnesota has a rich history dating back to 1857 when the Archibald brothers established a flour mill that became central to the town's development. Today, this small city of just under 2 square miles continues to honor its milling heritage while carefully managing modern growth.
