The following sections set forth standards for uses or structures applicable in all zoning districts.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-301. - One principal building per lot.

Every building erected after the adoption of this chapter from which this chapter is derived shall be located on a lot, as defined herein and in no case shall there be more than one principal building on any one lot, except as may otherwise be provided herein.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-302. - Structures on outlots.

No structures shall be constructed or erected on an outlot other than signs or fences.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-303. - Easements.

No private buildings (principal or accessory), temporary or permanent structures, or uses may be located in, on, or over any public drainage and/or utility easements, except fences, driveways, parking lots, or easily-movable structures that do not impede the flow of water and do not have permanent foundations as described elsewhere in this chapter and as determined by the city engineer; and public or quasi-public utilities or facilities regulated by city franchise or other provisions of the City Code. The items constructed within an easement are subject to removal at the property owner's expense in the event work on the utilities in the easement is needed.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-304. - Adequate public infrastructure.

All developments must provide adequate infrastructure suitable for the anticipated traffic, pedestrian circulation, and utility needs of the use. The city is authorized to require any necessary upgrades of adjacent and area public roadways and utilities directly related and proportional to a proposed development. Examples of such improvements are, but not limited to, construction or striping of turn lanes, installing or upgrading utilities, installing sidewalks, and/or installing street lights. All such expenses are the responsibility of the property owner of the proposed development.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-305. - Sanitary sewer and water connections.

(a)

All new principal structures within the Metropolitan Urban Services Area (MUSA) as designated on the current comprehensive plan must be connected to municipal sanitary sewer and water.

(b)

For an undeveloped parcel within an urbanized zoning district that is not directly serviced by municipal sanitary sewer and water, reasonable efforts must be made to extend sanitary sewer and/or water mains to the site prior to constructing a principal structure. This may be accomplished by developer utility construction or by an assessment agreement. If it is not reasonably feasible to extend sanitary sewer and/or water mains, a building permit may be issued with private systems.

(c)

In areas of the city outside of the current Metropolitan Urban Services Area (MUSA) where municipal water mains are located, the owner of a property directly adjacent may petition the city council for a water connection in the event an existing well becomes inoperable or contaminated. In no case shall the property be considered for rezoning to an urbanized district.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-306. - Small utility services.

All buildings constructed after the adoption date of this chapter shall be served by undergrounded utilities (natural gas, electric, cable, telephone, etc.) extending from the public right-of-way to the building.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-307. - Construction trailer/field office.

Construction trailers and field offices may only be placed and used in conjunction with an active building, utility, or grading permit onsite.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-310. - Lighting.

The purpose of this section is to provide regulations to balance lighting needs for visibility and personal and property safety with the negative impacts of off-site light spill-over.

(1)

Wall lighting may be used to illuminate the pedestrian walkways, entrance areas, loading docks, and yard areas within 20 feet of the building. No wall lighting may be used exclusively to illuminate areas for motor vehicle parking or access.

(2)

Architectural lighting, including LED or neon banding, must be mounted on the building or canopy. Architectural lighting directed upward onto the building façade is permitted provided no glare or light pollution are produced. LED banding must use colored tube shielding for a continuous appearance.

(3)

Free-standing and wall-mounted luminaire regulations:

a.

Height maximums, including the base and support structure, are limited as follows:

1.

Farther than 200 feet from any residential use or mixed-use property containing residential uses: 30 feet.

2.

Within 200 feet of any residential use or mixed-use property containing residential uses: 20 feet.

b.

Cut-off angles must be equal to or less than 90 degrees.

c.

Ballfield, stadium, or outdoor recreation lighting is exempt from the height and cut-off angle requirements in this section though the design shall constitute the absolute minimum height necessary to light the area and must provide shielding to reduce off-field light spill.

(4)

Lighting intensity must adhere to the following table:

Required Minimum and Maximum Light Intensities
(as measured in foot candles at the ground level)
Use Minimum
Intensity
Maximum
Intensity
Maximum
Intensity at
Property Line*
Parking areas for non-residential uses 1 15 0.5

Non-specified uses - For uses not specifically listed above, light requirements may be computed by the zoning administrator.

 

* Except along a common property line in areas where a shared parking agreement is in place.

(5)

Exterior lighting must be operational when a business is open or employees are on site.

(6)

Glare. All lighting must be arranged so as not to produce glare. All properties must be in compliance with the following:

a.

All light sources must be controlled and equipped with lenses, louvers, shields, or prismatic control devices designed to prevent off-site views of the light source.

b.

No flickering or flashing lights except those associated with public safety activities may be permitted.

c.

(7)

Compliance. Any new lighting installed after the effective date of this chapter must be in compliance with the requirements of this chapter. Any lighting in existence before the effective date of this chapter that does not comply with its requirements may be considered legally nonconforming and may be allowed to continue in compliance with section 106-140. Lighting may be required to be upgraded, wholly or in part, due to a request for a site plan review, conditional use permit, interim use permit, variance, or plat.

(8)

Seasonal decorative lighting and landscape lighting are not regulated by this section.

(Ord. No. 23-14, § 3, 11-14-2023; Ord. No. 24-10, § 2, 7-23-2024)

Sec. 106-320. - Driveways and curb cuts.

The owners of a corner lot may elect to access the principal building on either street that the lot abuts. In cases of lots with more than one street frontage, the city shall determine which street the building fronts and accesses. In cases where one of the streets is a county, state or MSA street, the lot shall access on the other street. Where any such election is manifestly contrary to the established character or welfare of the neighborhood, the request shall be referred to the city council for approval or disapproval.

(Ord. No. 23-14, § 3, 11-14-2023)

Sec. 106-322. - Vision clearance triangle.

A vision clearance triangle shall be established at each intersection corner in order to provide adequate site distance. The vision triangle shall be formed by creating a third leg that connects the ends of two legs that are in line with the face of the existing curbs. On streets which have a stop condition the length of the leg shall be 25 feet from the nearest face of the curb on the cross street being approached and shall be 50 feet for streets without stop conditions. The vision triangle shall also apply at alleys and at commercial driveways with the leg distance of 25 feet. The vision triangle shall be three dimensional and shall extend from 30 inches to nine feet above the top of curb. Where the wording herein refers to horizontal measurement from the face of curb and no curb exists, the edge of pavement shall be used instead. Where the wording herein refers to vertical measurement from top of curb and no curb exists, the measurement shall begin six inches above the pavement. The vision clearance triangle shall contain no fence, structure, earth bank hedge, planting, wall or other sight obstruction. The following are exempted: Utility poles, fire hydrants, traffic signals and signs, trees trimmed to the trunk, and plant species of open growth habit that are not planted in the form of a hedge and which are planted and trimmed as to leave an unobstructed view in all seasons. There shall be no parking allowed along the curbs within the vision triangle. Construction of new buildings or new additions to existing buildings that extend into the vision triangle shall not be permitted. Existing buildings shall not be considered an obstruction under the terms of this division. The city engineer may waive this provision where the natural contour of the ground is such that there can be no cross visibility at the intersection. Landscaping with the vision clearance triangle that is in existence prior to the date of adoption of the ordinance from which this division is derived shall be viewed on a case-by-case basis to determine whether these landscaping elements are in compliance with this division. The public works committee shall render the final decision on such determinations.

Sec. 106-351. - Tree preservation purpose and intent.

(a)

Purpose. The city council finds it is in the best interest of the city to protect, preserve, and enhance the natural environment by encouraging a resourceful and prudent approach to development and alteration of wooded areas. The city council also recognizes that some amount of tree loss is an inevitable consequence of the development process. The tree preservation regulations herein attempt to maintain a balance between one's rights to develop property with the needs and desires of the community to protect the natural environment.

(b)

Intent and objectives. The intent of this section is to support the preservation and protection of significant trees, or stands of trees, to promote the orderly development of such areas and minimize public and private losses. The following regulations address the removal of trees associated with new development. The city council finds that the following objectives are important to achieve the purpose and intent of this division:

(1)

To continue to seek recognition as a Tree City U.S.A. and to take all reasonable steps to promote planting and conservation of trees throughout the city;

(2)

To maintain and preserve the many benefits that trees provide including, but not limited to, the following:

a.

Character and aesthetics.

1.

Trees help buffer different or conflicting land uses by establishing visual screening and buffering noise, glare and heat abatement;

2.

Trees conserve and enhance the city's quality of life and ecological and aesthetic environment, especially its valuable and rural atmosphere; and

3.

Trees provide important psychological benefits to the people within the city and neighborhoods.

b.

Wildlife habitat. Trees are essential to maintain wildlife habitat within the city.

c.

Energy conservation. Trees assist in the moderation of climate by providing shade, windbreaks, and the cooling of air; thereby reducing the requirements for air conditioning and heating and the subsequent utilization of energy resources.

d.

Improved air and water quality.

1.

Trees aid in the filtering of stormwater as it passes through the soil to the groundwater;

2.

Trees maintain permeable land areas essential to surface water management and aquifer recharge; and

3.

Trees aid in the purification of the air through the removal of carbon dioxide, the generation of oxygen, and the precipitation of dust and other airborne pollutants.

e.

Socioeconomic.

1.

Trees enhance property values; and

2.

Trees protect and preserve the unique identity and environment of the city and aid in the development of the economic base attracted to the city by such factors.

f.

Erosion and flood control.

1.

Trees aid in the stabilization of soil by the prevention of erosion and sedimentation; and

2.

Trees reduce stormwater runoff and the costs associated therewith and aid in the replenishment of groundwater supplies.

g.

Privacy and buffering. Preservation of existing trees helps maintain privacy and establishes a buffer between conflicting uses or varying residential densities.

(c)

Administration.

(1)

The city shall administer and enforce the provisions of this division. The city is authorized to cause inspections on a scheduled basis when reason exists to believe that a violation of this division has been or is being committed.

(2)

Sec. 106-370. - Communications towers.

(a)

Purpose. In order to accommodate the communication needs of residents and business while protecting the public health, safety, and general welfare of the community, the council finds that these regulations are necessary in order to:

(1)

Facilitate the provision of wireless telecommunication services to the residents and businesses of the city;

(2)

Minimize adverse visual effects of towers through careful design and siting standards;

(3)

Avoid potential damage to adjacent properties from tower failure through structural standards and setback requirements; and

(4)

Maximize the use of existing and approved towers and buildings to accommodate new wireless telecommunication antennas in order to reduce the number of towers needed to serve the community.

(b)

Towers in residential zoning districts. Construction of towers to support commercial antennas that conform to all applicable provisions of this Code may be allowed only the following locations:

(1)

Parcels within the Tower Overlay District as shown on the official zoning map.

(2)

All religious institution, government, school, utility, and institutional sites.

(3)

If the proposed tower is to be located within a residential district, documentation must be included in the application that demonstrates that the tower cannot be reasonably located within a commercial, industrial, or public/quasi-public zoning district.

(c)

Towers in COR and Mississippi River Corridor Critical Area Overlay Zoning Districts. Construction of towers to support commercial antennas shall not be allowed in Town Center and Critical River Overlay Zoning Districts, except that antennas may be attached to existing structures provided the antenna does not extend more than 20 feet above the highest point of the structure or tower.

(d)

Collocation requirements. All commercial wireless telecommunication towers erected, constructed, or located within the city shall comply with the following requirements:

(1)

A proposal for a new commercial wireless telecommunication service tower shall not be approved unless the city council finds that the telecommunications equipment planned for the proposed tower cannot be accommodated on an existing or approved tower or building within a one-mile search radius of the proposed tower due to one or more of the following reasons:

a.

The planned equipment would exceed the structural capacity of the existing or approved tower or building, as documented by a qualified and licensed professional engineer, and the existing or approved tower cannot be reinforced, modified, or replaced to accommodate planned or equivalent equipment at a reasonable cost.

b.

The planned equipment would cause interference materially impacting the usability of other existing or planned equipment at the tower or building as documented by a qualified professional and the interference cannot be prevented at a reasonable cost.

c.

Existing or approved towers and buildings within the search radius cannot accommodate the planned equipment at a height necessary to function reasonably as documented by a professional engineer.

d.

In spite of its best efforts, within 60 days, the applicant was unable to obtain approval to collocate on an existing or approved tower or building.

e.

Other reasons that make it impractical to locate the planned telecommunications equipment upon an existing or approved tower or building.

(2)

Shared use of existing communications towers shall be preferred to the construction of a new tower. Any proposed commercial wireless telecommunication service tower shall be designed structurally, electrically, and in all respects, to accommodate both the applicant's antennas and comparable antennas for at least two additional users.

(e)

Tower construction requirements. All towers erected, constructed, or located within the city, and all wiring therefor, shall comply with the requirements set forth in chapter 105.

(f)

Tower and antenna design requirements. Proposed or modified towers and antennas shall meet the following design requirements:

(1)

Towers and antennas shall be designed to blend into the surrounding environment through the use of color and design, except in instances where the color is dictated by federal or state authorities such as the Federal Aviation Administration. Tower architectural standards are subject to final city council approval.

(2)

Commercial wireless telecommunication service towers shall be of a monopole design unless the city council determines that an alternative design is preferred in cases where structural or design considerations, neighborhood compatibility, location availability, or the number of potential collocations warrants this consideration.

(3)

All towers must be designed so that the tower site and setbacks will contain guyed wires, debris, and the tower in the event of a collapse, except towers of monopole design.

(g)

Tower bulk standards. Towers shall conform with each of the following requirements:

(1)

No part of any communication antenna or tower, equipment, guyed wires, or braces shall at any time extend across or over any part of the public right-of-way, public street, highway, sidewalk, or recreation trail.

(2)

In business and industrial zoning districts, towers shall meet the setbacks of the underlying zoning district with the exception of industrial zoning districts, where towers may encroach into the side or rear setback area, provided that the side or rear property line abuts another nonresidential zoned property and the tower does not encroach upon any easements. When adjacent to a residential district, the tower must meet the setback equal to the height of the tower plus ten feet or the setbacks of the underlying zoning district, whichever is greater.

(3)

Towers constructed within the Tower Overlay and Public/Quasi-Public Zoning Districts shall maintain a minimum setback equal to the height of the tower plus ten feet from any lot line.

(4)

Towers shall not be located between a principal structure and a public street, with the following exceptions:

a.

In business zoning district, towers may be placed within a side yard abutting right-of way.

b.

On sites adjacent to public streets on all sides, towers may be placed within a side yard abutting a local street.

(5)

The setback shall be measured between the base of the tower located nearest the property line and the actual property line.

(6)

A tower's setback may be reduced or its location in relation to a public street varied, at the sole discretion of the city council, to allow the integration of a tower into an existing or proposed structure such as a church steeple, light standard, power line support device, or similar structure.

(7)

The height of a communication tower shall not exceed:

a.

One hundred feet in residential districts.

b.

One hundred ninety-nine feet in business districts, with no additional height allowances granted.

(8)

Multi-user towers may exceed the height requirements as stated in this section by up to an additional 20 feet provided that two additional users, as stated in subsection (7) of this section, have collocated their antennas on the monopole structure.

(9)

The city council may increase the height of a tower if the applicant is able to demonstrate to the satisfaction of the city council that the surrounding topography, structures, vegetation, and other factors make the height limit for a complying tower impractical.

(h)

Tower lighting. Towers shall not be illuminated by artificial means and shall not display strobe lights unless such lighting is specifically required by the Federal Aviation Administration or other federal or state authority for a particular tower, or if required by the city council for safety reasons. When incorporated into the approved design of the tower, light fixtures used to illuminate ball fields, parking lots, or similar areas may be attached to the tower.

(i)

Signs and advertising. The use of any portion of a tower for signs other than warning or equipment information signs is prohibited.

(j)

Accessory utility buildings. All utility buildings and structures accessory to a tower shall be architecturally designed to blend in with the surrounding environment and shall meet the minimum setback requirements of the underlying zoning district. Ground-mounted equipment shall be screened from view by suitable vegetation, except where a design of non-vegetative screening better reflects and complements the architectural character of the surrounding neighborhood, as determined by the city council.

(k)

Abandoned or unused towers or portions of towers. Abandoned or unused towers or portions of towers shall be removed as follows:

(1)

All abandoned or unused towers and associated facilities shall be removed within 12 months of the cessation of operations at the site unless a time extension is approved by the city council. A copy of the relevant portions of a signed lease which requires the applicant to remove the tower and associated facilities upon cessation of operations at the site shall be submitted at the time of application.

(2)

Unused portions of towers above a manufactured connection shall be removed within 12 months of the time of antenna relocation. The replacement of portions of a tower previously removed requires the issuance of a new conditional use permit.
