CITY PROPOSAL:

 

The city of Duluth does ordain:

                     Section 1. That Section 50-26 of the Duluth City Code, 1959, as amended, be amended as follows:

50-26                     Screening, walls and fences.

50-26.1                     Screening of mechanical equipment.

A.                     Applicability.

The standards of this Section shall apply to all of the following uses that contain a primary structure in all zones, except I-G and I-W: a multi-family, mixed use, commercial, institutional, industrial, or parking principle use, when any of the following conditions occur:

1.                     A new primary structure is constructed;

2.                     The floor area in an existing primary structure(s), taken collectively, is increased by more than 25 percent;

3.                     An existing primary structure is relocated on the lot or parcel;

4.                     The primary structure is renovated or redeveloped (including but not limited to reconstruction after fire, flood or other damage), and the value of that renovation or redevelopment, as indicated by building permits, is 25 percent or more of the pre-application assessor's market value of the primary structure, as shown in the records of the city assessor.

The standards of this Section shall not apply if the only feasible location for mechanical screening would impede the functioning of solar, wind or geothermal energy equipment or systems if such systems are otherwise in compliance with applicable building codes and zoning requirements;

B.                     Screening standards.

                     The following exterior mechanical features shall be screened:  (i) electrical and gas-powered mechanical equipment and power systems equipment; (ii) heating, ventilating and air conditioning equipment ductwork, and lines;  and (iii) power systems equipment. Roof or wall-mounted antennas and vent openings shall not be considered mechanical equipment for purposes of these screening standards.

 

1.                     Roof-mounted mechanical equipment.

Roof- mounted mechanical equipment shall be screened by a parapet wall or similar feature that is an integral part of the building’s architectural design.  The parapet wall or similar feature shall be sufficient to screen the mechanical equipment from ground view of a person on the other side of the public right-of-way on which the structure fronts, as illustrated in Figure 50-26.1-A;

2.                     Ground-mounted mechanical equipment.

Ground-mounted mechanical equipment shall be screened from view from ground view of adjoining properties and public right-of-way by landscaping or by a decorative wall that incorporates at least one of the primary materials and colors of the nearest wall of the primary structure.  The wall shall be of a height equal to or greater than the height of the mechanical equipment being screened.  If landscaping is used for screening, the screening material shall be designed to provide 75 percent opacity one year after planting along the full required height and length of the screening buffer.  (Ord. No. 10044, 8-16-2010, § 6; Ord. No. 10096, 7-18-2011, § 36; Ord. No. 10153, 5-14-2012, § 9.)

The maximum height of a fence or wall within required side and rear yard area is eight feet.  The maximum height for fences and walls for entry gates at the residential subdivision entrance shall be eight feet;

4.                     Mixed use and special purpose zone districts.

The maximum height of a fence or wall within required side and rear yard area is eight feet, but the land use supervisor may approve a fence or wall up to 12 feet in height where additional height is needed to provide adequate security because of topography or the nature of the material or equipment stored in the area;

5.                     Form districts.

The maximum height of a fence or wall within required side and rear yard area is eight feet, but the land use supervisor may approve a fence or wall up to 12 feet in height where additional height is to provide adequate security because of topography or the nature of the material or equipment stored in the area.  Fences and walls are not permitted in required front yard areas, except for wrought iron fences used to enclose outdoor patio or dining areas, in which case the maximum height of the fence shall be three feet;

6.                     Vacant property.

As an exception to other fence height limits, vacant property may be fenced with chain-link fencing not to exceed six feet in height when the purpose of such fencing is to prevent unauthorized dumping or soil disturbance that results in fugitive dust or nuisance conditions.  Such fencing of vacant property shall not be construed to allow use of the property for outdoor storage;

7.                     Permit required.

No fence shall be constructed in dedicated rights of way without a concurrent use permit. Any fence that exceeds seven four feet in height is required to have an approved zoning permit prior to construction.

Statement of Purpose

STATEMENT OF PURPOSE:  This ordinance implements three minor text amendment to chapter 50 of the City Code, known as the Unified Development Chapter (UDC).

 

The first minor change is the applicability standards for screening of mechanical equipment,  No additional standards are applied; the langue is simply edited to be clearer.  The second change is to allow vinyl-coated chain link fences, no more than four feet tall in height, in the front yard.  The final change is to require a zoning permit for all fences four feet and greater.  The zoning permit will be issued administratively, and will require an accurate site plan in order to ensure that fences are not constructed over property lines, in public right of ways, or blocking trail or pedestrian easements.  As per the state building code, only fences above seven feet in height require a building permit. 

 

The planning commission held a public hearing and considered the changes at their January 9 and February 13, 2018, regular planning commission meetings.  At their special annual meeting on March 6, 2018, they voted 9-0 to recommend that the city council approve this ordinance change.
