The purpose of the Z6 Industrial District is to promote the management and preservation of existing industrial facilities within Mason City as well as the development and management of new ecologically responsible, sustainable employment centers. Building forms and functions within the Z6 District require varying degrees of separation from residential and commercial/service districts due to their potential for noise, bright lighting, traffic from heavy trucks and other large vehicles, rail traffic and round the clock activities associated with research and development, manufacturing, warehousing, freight terminals and agribusiness.

(Ord. 10-003, 1-19-2010, eff. 7-1-2010)

Permitted forms and functions, which are identified in section 12-8-3, table 2 of this title, are those that are allowed by right within Mason City. New development or redevelopment will require a site plan drawn to scale showing that all zoning standards in chapter 16 of this title have been met. (Ord. 10-003, 1-19-2010, eff. 7-1-2010; amd. 2017 Code)

Conditional forms and functions, which are identified in section 12-8-3, table 2 of this title, are those that must be reviewed and approved by the board for potential impact on neighboring properties. All conditional forms and functions shall conform to the standards set forth in section 12-5-5 of this title. New development or redevelopment shall be reviewed according to chapter 7 of this title to show compliance with all development standards identified herein. (Ord. 10-003, 1-19-2010, eff. 7-1-2010; amd. 2017 Code)

   A.   All buildings shall be considered principal buildings in this zoning district.

   B.   Structure standards for trash enclosures are defined in section 12-16-12 of this title. (Ord. 11-3, 2-15-2011)

Any development, lot of record or structure legally operated prior to July 1, 2010, shall be considered a permitted use and legally conforming within this zoning district. Any redevelopment or addition to a development, lot of record or structure shall be required to conform to the forms and functions and development standards found within this zoning district. Any change in form or function shall conform to permitted and conditional form and function standards as described in this zoning district. (Ord. 10-003, 1-19-2010, eff. 7-1-2010)

   A.   Forms and functions that create hazards, excessive noise, vibrations, smoke, dust, odors, glare or other objectionable influence beyond the property boundaries shall constitute an open industry designation and be subject to applicable standards.

   B.   Self Storage:

      1.   All access drives and parking areas adjacent to self storage buildings shall be paved with a hard and durable, dustless surface and shall provide for stormwater drainage according to city engineering standards. Paving shall extend at least eighteen feet (18') from any building wall containing storage unit access doors. Permeable non-aggregate surfaces are permitted. Areas dedicated to outdoor vehicle storage may utilize gravel or similar aggregate material.

      2.   Self storage units may be utilized only by the owner or lessee of the unit and may not be used for commercial purposes. A self storage unit may be used as a personal hobby building, if permitted by the owner. (Ord. 10-003, 1-19-2010, eff. 7-1-2010; amd. Ord. 20-10, 11-3-2020; Ord. 21-5, 6-1-2021)

Open industry development consists of large, relatively self- contained and isolated facilities whose potential nuisance or hazard generation from the processing, manufacturing, assembly, storage and distribution of materials and products is moderately high or higher. (Ord. 10-003, 1-19-2010, eff. 7-1-2010; amd. 2017 Code)

Functions that produce emissions of noise, vibration, smoke, dust or other particulate matter, toxic materials, odor or glare shall not exceed the standards set by the Iowa Department of Environmental Quality. Storage, distribution or sale of gas, fuel or oil shall comply with and be approved by the Fire Chief. (Ord. 10-003, 1-19-2010, eff. 7-1-2010)

   A.   Restricted industry development consists of facilities whose manufacturing, assembly, storage and distribution activities do not create appreciable nuisances or hazards, or that require a pleasant, hazard and nuisance free environment. It is intended that the permitted functions be compatible and not detrimental to adjacent properties.

   B.   Live/work building functions shall only be allowed as a conditional use in Z6 R Districts. (Ord. 11-10, 9-6-2011)

See section 12-8-3, "Zoning Form And Function Table", of this title. (Ord. 14-1, 1-7-2014)
