Mixed-Use District

The MU zoning district is designed to accommodate a wide variety of commercial and retail activities that will result in the most efficient and attractive use of the City's historic business district and the US 1 corridor, in an effort to recognize the role of US1 as the City of Marathon's Main Street. Specifically, this district provides for land uses that have a strong pedestrian-oriented character, with a mixture and concentration of specialty shopping, transient lodging, retail, personal service, restaurant, cultural, fishing industry, affordable housing and entertainment uses in the Old Town area. The MU district also provides for large-scale retail and commercial business opportunities in other areas, including larger shopping centers, specialty shopping centers, individual multi-tenant commercial buildings, automobile services and sales, fast food restaurants, affordable housing residential uses, transient lodging and other retail establishments that serve the community at large. The MU district is designated within the Mixed-use Commercial (MUC) future land use category on the Future Land Use Map FLUM.
