The provisions in this article provide standard regulations for the location, design, and development of all properties in all base districts. The purposes of these standard regulations are:
A. 
To ensure that the development of property protects the public, health, safety and welfare of the community;
B. 
To protect property values and rights of all residents;
C. 
To protect and enhance the community's assets and natural resources; and
D. 
To establish minimum standards of property maintenance and aesthetics.
(Ord. 898-08, 9-8-2008)
The provisions apply to all new development and the substantial alteration of existing development in all base districts, unless a development is proposed within an overlay district, then the provisions of the overlay district may supplant these regulations.
(Ord. 898-08, 9-8-2008)
A. 
Applicability: All new fences and retaining walls shall be required to be in conformance with this section. Legal nonconforming fences and retaining walls may remain so as long as there are no significant improvements to the site or they are specifically conditioned in a conditional use permit.
B. 
Permit Required:
1. 
Anyone constructing a fence or wall over eight feet in height shall first obtain a design review approval and a building permit from the city prior to construction.
2. 
Any fence located in the floodway shall secure applicable permit(s) from the city and all agencies with jurisdiction prior to construction.
C. 
Height and Setback Requirements:
1. 
Fences along public street frontages or within front yard setbacks shall not exceed three and one-half feet in height. However, fences may be up to six feet in height if:
a. 
They are set back to be flush or behind a permanent building; or
b. 
In the absence of a building the fence shall be set back minimally 10 feet from the back of sidewalk, or in the absence of a sidewalk the fence shall be set back 10 feet from where a code compliant future sidewalk would be located, so as to allow for street trees and landscaping between the fence and the sidewalk system. The area between the fence and the sidewalk, or a future sidewalk, shall be maintained with Type A or Type B landscaping.
2. 
Fences and retaining walls are prohibited within five feet of the Greenbelt or Nature Path travel way.
3. 
Fences located within five to 15 feet of the Greenbelt or Nature Path travel way, or adjacent to a public park shall not exceed three and one-half feet in height, unless:
a. 
The fence is six feet in height or less and is concealed from view with Type A landscaping between the fence and the Greenbelt or Nature Pathway; or
b. 
The fence is six feet in height or less, is designed to be see-through or non-privacy (e.g., wrought iron), and is accompanied by Type B landscaping between the fence and the Greenbelt or Nature Pathway.
4. 
Fences located along a residential rear yard, or a side yard setback shall not exceed six feet in height.
5. 
Fences located within rear or interior side yards between residential and nonresidential uses, or between nonresidential uses shall not exceed eight feet in height.

8. 
Fence and retaining wall setbacks and height limitations cannot be amended by the Planned Unit Development process.
D. 
Design Standards:
1. 
Fences and retaining walls shall be designed and constructed of materials that do not pose a safety hazard to users of sidewalks, the Greenbelt, Nature Path, parks, or adjacent properties.
2. 
Fences and retaining walls shall not obstruct the clear vision triangle or access to required parking, public utility boxes, meters, or other infrastructure.
3. 
Retaining walls adjacent to the public realm shall provide at least three feet of landscape area, between the public space and the retaining wall.
4. 
If a fence or a retaining wall is placed on top of a retaining wall, the fence or retaining wall must be set back one inch for every one inch that the combined height exceeds the fence height limitations. Setback areas greater than one foot shall be a landscape area.
E. 
The use of barbed wire, razor wire, boxes, sheet metal, old or decayed wood, broken masonry blocks, chain link, chain link with slats, or other unsightly materials for fencing is prohibited unless a design review application is approved by the planning official, demonstrating:
1. 
The use of the materials is not in conflict with the comprehensive plan;
2. 
The fence is constructed of professional and durable materials and is not intended to be of a temporary nature; and
3. 
The fence provides significant creativity and uniqueness, and the intent is not to merely evade the provisions set forth in this section; or
4. 
The fence is an established icon that enhances the community’s assets more than a fence complying with the requirements set forth in this section.

A. 
Purpose: The provisions of this section are intended to improve water quality and provide a natural, effective form of flood and water pollution control through the integration of vegetated, well designed stormwater filtration swales into required landscape areas, where topography and hydrologic features allow.
B. 
Applicability: The standards for stormwater integration shall apply to all subdivisions, site improvements and ACHD stormwater facilities.
C. 
Standards:
1. 
Stormwater swales incorporated into required landscape areas shall be vegetated with grass or other appropriate plant materials. Such swales shall also be designed to accommodate the required number of trees as per subsection 8-4I-4A, "Landscaping For Single-Family Residential Units", of this chapter if located in a required landscape area.
2. 
A rock sump may be incorporated into a vegetated swale to facilitate drainage. The rock sump inlet may not exceed more than five feet (5') in any horizontal dimension. Grates for sand/grease interceptors may also be incorporated, but the inlet structures may not exceed two feet (2') in any horizontal dimension.
3. 
Gravel, rock, or cobble stormwater facilities are not permitted on the surface of required landscape areas, unless designed as a dry creek bed or other design feature.
4. 
Plant materials shall be a species that are able to withstand the anticipated changes in soil wetness and moisture levels.
5. 
Organic mulch shall not be used against drainage catch basins due to potential sediment clogging.
6. 
Slopes shall be less than three to one (3:1) (horizontal to vertical) for accessibility and maintenance.

a. 
The maintenance of the irrigation ditch, lateral, canal, or drain with any associated easement encumbers more than fifty percent (50%) of the property; or
b. 
The irrigation ditch, lateral, canal, or drain is located on the property in such a manner that a use of the property is infeasible; or
c. 
The irrigation ditch, lateral, canal, or drain is enclosed on both ends adjacent to the property, and the adjacent properties are fully developed in a manner that future opening of the enclosed irrigation ditch, lateral, canal, or drain is infeasible.
3. 
Irrigation ditches, laterals, canals, and drains do not require fencing. If fencing is installed, open fencing only is allowed, and privacy fencing is prohibited. All fencing shall be approved by the irrigation or drainage district.
4. 
For any irrigation or drainage ditch, piping or alteration of the ditch shall not impede the movement of the amount of water crossing the property prior to development or the amount of water delivered to downstream properties.
5. 
In no circumstances shall structures be built over irrigation ditches, laterals, canals and drains or within their dedicated easements.
