§ 4.70 FENCES.
   Subd. 1.   Purpose. 
      A.   Standards governing fences are established to promote the public health, safety and welfare, encourage an aesthetic environment and allow for privacy, while maintaining access to light and air.
      B.   Fence. Any partition, structure or gate erected as a dividing marker, barrier or enclosure.
   Subd. 2.   Permit required. It is unlawful for any person to construct, erect or cause to be constructed or erected in the city any fence without first obtaining a permit from the city. Seasonally installed fences for snow and landscape protection may be installed temporarily (less than six mos.) without permit.
   Subd. 3.   Application and fee. Every person desiring to erect or construct a fence shall apply for a permit to the Planning, Zoning and Building Department. The application shall be accompanied by a fee fixed by resolution of the Council.
   Subd. 4.   Investigation of premises and issuance. In the event a fence is not permitted or is not in compliance with city ordinance, the Planning and Zoning Administrator shall report the matter to the Council for their consideration and the decision of the Council on the issuance of the permit or removal of the fence shall be conclusive. Any fence constructed in a utility easement shall be removed as necessary for utility maintenance and repair, at the owner's expense. Fences shall not be constructed in the public right-of-way.
   Subd. 5.   Construction requirements in residential and multiple dwelling area. It is unlawful for any person to construct, erect or cause to be constructed or erected in the city in any residential or multiple dwelling area, as defined in Chapter 11 , any fence, unless the fence shall, in its construction and location, conform to the following requirements:
      A.   A solid or opaque lot line fence constructed along or adjacent to a front yard or corner yard lot line shall not exceed 36 inches in height. A 15 foot sight triangle shall be maintained where a fence will interfere with traffic or pedestrian visibility across a driveway, street, alley or sidewalk. The sight triangle is measured along the curb for streets and the sidewalk/property line for driveways and alleys. The maximum fence height may be increased by 12 inches if constructed of open, decorative or ornamental fencing materials less than 50 percent opaque. Fences may not be modified so as to become solid or opaque fences except as otherwise allowed in this paragraph.

Installation of barbed wire may be considered by the Planning Commission and Council where special circumstances exist. Planning Commission shall recommend to approve or deny a request and the decision of Council shall be conclusive.

   Subd. 10.   Maintenance; declaration and abatement of nuisance.
