Duluth UDC § 501.03

a. A “major subdivision” is any subdivision that does not qualify as a “minor subdivision.” A major subdivision commonly involves the construction of a new street or widening or other improvement of an existing roadway, the provision of stormwater drainage facilities, or the construction or improvement of public utilities, or which has six or more lots (not in a large lot minor subdivision), building sites or other divisions. b. Major subdivisions fall into the following categories for the purpose of development regulation: 1. Conventional subdivisions, in which the minimum lot size allowed for the zoning district determines the maximum number of lots in the subdivision, and all of the lots meet the minimum lot size for the zoning district as shown in the Use of Land and Structures Article of this Development Code. Common open space outside of the lots may be created, but is not required, with the exception that conservation areas as defined by this Article are required to be protected (see Section 505). 2. Conservation subdivisions, in which the maximum number of lots that would be allowed in a traditional subdivision under the property’s zoning determines the maximum number of lots in the subdivision, but the minimum lot size may be reduced in response to a higher level of development standards and in order to create more conservation areas and recreational amenities for the residents. 147 | P a g e Article Five. Subdivisions and Planned Developments 3. Planned unit developments (PUDs), in which a mixture and/or increased density of land uses is allowed in response to a higher level of development standards and in order to efficiently use the land and organize uses. 4. Other planned developments, which include manufactured home parks, apartment buildings and complexes, condominiums, and commercial developments consisting of three or more businesses. For the purposes of this Article, planned developments other than PUDs are controlled by the provisions of their respective zoning districts. c. Permanent Protection Required. All conservation areas in a conventional subdivision, conservation subdivision or PUD that are required to be protected by the provisions of this Article, shall be permanently protected from further subdivision, development, and unauthorized use, by the method described in Section 505 of this Article. d. Summary Table. Table 5-A presents a summary of the requirements of this Article as they apply to each of the types of major subdivisions and developments.
