§ 150.11 GENERAL PERFORMANCE STANDARDS FOR ALL PROPERTIES.
   (A)   Intent. It is the intent of this section to guide development so as to create a compatible relationship of land uses by maintaining certain standards. Within the various districts, the permitted uses, conditional uses, and accessory uses shall conform to these standards. Standards listed herein shall be construed as minimum standards and the City Council may require adherence to approved or suggested State of Minnesota standards.
   (B)   Compliance. In order to ensure compliance with the performance standards set forth herein, the Planning Commission may require the owner or operator of any facility to have made the investigations and tests as may be required to show adherence to the performance standards. The investigation and tests as are required to be made shall be carried out by an independent testing organization as may be selected by the city, at the applicant’s expense.
   (C)   Landscaping. All required yards shall either be landscaped or be left in a natural state. Any area left in a natural state shall be property maintained in a sightly and well-kept condition. Businesses in the highway business district and industrial district adjoining any residential structures shall be landscaped with either a fence or buffer planting screens at least 5 feet in height. Plans of the screens shall be submitted for approval as a part of the site plan and installed prior to the commencement of operation.

Noise shall be muffled so as not to become objectionable due to intermittence, beat frequency, shrillness or intensity, except for noise from agricultural sources in the A-1 Agriculture District generated by agricultural use shall be exempt.
   (E)   Odors. Any use established, enlarged, or remodeled shall be so operated as to prevent the emission of odorous matter of the quantity as to be readily detectable at any point beyond the lot line of the site on which the use is located. Detailed plans for the prevention of odors crossing property lines may be required before the issuance of a zoning permit, except odors from agricultural sources.
   (F)   Glare. Glare, whether direct or reflected, such as from floodlights or high temperature processes, and as differentiated from general illumination, shall be directed at or illuminate adjacent properties.

   (I)   Smoke and particle matter. Any use established, enlarged, or remodeled after the effective date of this chapter shall be so operated to meet the minimum requirements of the Minnesota Pollution Control Agency for the emission of smoke or other particulate matter.
   (J)   Dust. Solid or liquid particles shall not be emitted at any point in concentrations exceeding standards set forth by the Minnesota Pollution Control Agency, Department of Health, or other federal or state agency.
   (K)   Toxic or noxious matter. Any use established shall be so operated as not to discharge across the boundaries of the lot or through percolation into the subsoil beyond the boundaries of the lot wherein the use is located, toxic or noxious matter in the concentration as to be detrimental to or endanger the public health, safety, comfort, or welfare, or cause injury or damage to property or business.

   (R)   Fences.
      (1)   All boundary line fences shall be entirely located upon the private property of the persons, firm, or corporation constructing, or causing the construction of the fence. All fences shall be set back at least 1 foot from all property division lines and those fences exceeding 3 feet in height shall maintain a 3-foot setback from a lot line unless:

      (4)   No fences shall be constructed within utility easements.
      (5)   All boundary line fences shall be constructed of decorative wood, decorative metal, decorative vinyl, or PVC or chain link fencing. Boundary line fences shall contain an adequate number of upright supports properly installed and the fence will be securely fastened to the supports to ensure that the fence shall remain in an upright position and not sag. Any type of fencing erected shall not be attached to trees. Snow fencing, barbed wire (unless used on the top of a fence otherwise constructed of chain link material and then only on a fence erected in a business or industrial district), woven wire, electric fence and other similar types of fencing are not permitted to be used as boundary line fences. Property owners shall maintain both sides of fences located on their property in reasonable repair and shall not be allow them to become and/or remain in a condition of disrepair or danger, or constitute a public or private nuisance. Fences shall be constructed with a finished side facing outward.
      (6)   Temporary fencing that meets a limited time use such as a seasonal fence to protect gardens from wandering animals, for crowd control or around a construction or demolition area or where a possibly hazardous condition may occur is permitted; however, these types of fences must be taken down as soon as the use is completed.
      (7)   Fencing to control the blowing of snow is also permitted; however, the fencing may only be erected between the dates of November 1 and April 1, or as soon after that date as the snow melts sufficiently to allow the fence to be taken down. Snow fencing shall meet the same height and setback requirements as those of boundary line fences.
      (8)   Hedges consisting of shrubs and other plantings in the front yard shall be no higher than 3 feet. On corner lots, no hedge or fence shall be erected, placed, planted, or allowed to grow in such a manner as would impede vision, obscure the view, or cause danger to traffic on a street, alley, or public road. All hedges shall be planted to meet the setback requirements from property lines that are required of fences when the hedges are mature. Hedges shall be maintained by the property owner upon which they are located so they do not constitute a nuisance to neighboring property owners or a danger to public health safety or welfare.
(Am. Ord. passed 12-7-1998)
   (S)   Lot survey requirements. In the cases where fences are being erected on property lines or structures are being enlarged within questionable distances of the applicable setbacks in districts, the Amboy Planning Commission will require the applicant (at the applicant’s expense) to have the lot surveyed and staked in order to insure compliance with those regulations established by the city.
   (T)   Limits on a request for a variance, conditional use permit, or amendment. A request for a variance, conditional use, or amendment which has been denied may not be requested again until a period of 6 months has passed unless the applicant can show to the satisfaction of the Planning Commission or Board of Adjustment that the conditions which were present under the earlier request filed have changed or that the request is substantially different.
