A. The OTN is characterized by older building stock and a mix of densely developed commercial and residential structures built on small lots served by alleys. The OTN includes Dubuque's historic downtown core, the Central Avenue and Rhomberg Avenue business corridors, older neighborhood commercial nodes often located on corner lots and a mix of single- and multi-family housing located on separate lots or as upper story apartments.
B. The purpose and intent of the OTN is to conserve the character and integrity of historic building stock in areas of the city where strict application of site design standards for new commercial and multi-family residential development are difficult to apply due to the dense development patterns of these older areas. Often, application of such "suburban style" standards may lead to demolition of existing structures or may limit redevelopment of commercial and multi-family structures or properties in the OTN.
