a. Temporary construction or snow fencing.

b.

This should not be read to prohibit the use of these materials for fencing for the purpose of garden or animal enclosures interior to a property.

c. Bright or fluorescent colors.

d. Slats, strips or other materials intended to increase opacity attached to or weaved through openings within a fence material, with the exception of sun and/or wind screen material designed for and directly associated with a sports or recreation facility, subject to the provisions of 9-10-4 A.21.

7. Provisions for landscaping to soften the presence of the fence and provide additional buffering or screening may be required and will be reviewed on a case by case basis. Not applicable between individual single-family lots.

8. Any fence that does not conform to this section, but is considered by the Director of Development Services, or his/her designee, to satisfy the spirit and intent of the ordinance may be approved at their discretion.

B. Height and Setback Requirements:

1. For the purposes of determining height and setback allowances:

a. The front yard shall be considered that side of a lot that lies forward of the main plane of the structure towards the street.

b. The side yard shall be considered that portion of the lot beginning at the rear lot line extending to a point formed by a line projected along the same plane as the front plane of the structure to the nearest side lot line.

c. The street side yard shall be the same as a side yard except that the side borders a street instead of another private lot.

d. The rear yard shall be considered to be that lot boundary generally parallel to the rear plane of the structure.

2. Unless minimum setback requirements are otherwise specified herein, or specifically approved by the City Council, all fences may be located on the property line or ultimate street right-of-way line, whichever is more restrictive.

3. Measuring Fence Height:

a. The height of the fence shall be determined by a measurement from the ground beneath the fence as follows:

(1) On a street side yard, the total effective height above the finished grade shall be measured on the side nearest the street. If a property or premises is lower than an adjacent street, then the effective height of the fence shall be determined by a measurement from the street grade at a ninety-degree (90°) angle from the fence. Up to an additional two feet (2') of height may be allowed to achieve an effective height of six feet (6'); however, the total vertical measurement from the ground beneath the fence to the top of the fence shall not exceed eight feet (8'). (See figure #4 of this section.)

(2). In any other yard the allowable height shall be the vertical measurement from the ground beneath the fence to the top of the fence.

Figure 4:

b. The intentional implementation of earthen berming, retaining wall, or raised planter for the sole purpose of achieving a height above that provided herein shall not be allowed in Single Family Residential districts. Fences may be located on top of retaining walls or raised planters in Single Family Residential as long as the top of the fence as measured from the bottom of the retaining wall or planter does not exceed eight feet (8') in total allowable height in the Residential Estate district or six feet (6') in total allowable height in all other Single Family Residential zoning districts.

4. Fence Height and Required Setback:

a. Upon issuance of a building permit, lawfully established legal non-conforming fences along the street side yard which existed prior to 2000 (as determined by aerial photographs, permit records, etc.) may be reconstructed/replaced only once in its current location, except that modifications to provide visual clearance, if necessary, must be made. Any subsequent reconstruction/replacement at its current location shall be prohibited and must meet the current setback requirements.

(1) City staff shall record a copy of the building permit for the rebuild.

b. All Districts, except as otherwise provided below in this section:

(1) Visual clearance as provided and illustrated elsewhere in this chapter shall be maintained at intersection of two (2) streets and at intersections of a street and private driveway. Provision of visual clearance may require the fence to be angled, reduced in height or of a design that allows visibility through the fence at the corner.

(2) The placement of a fence along the street side yard or rear lot line adjacent to a street does not negate the property owner’s responsibility of maintenance of the right of way (area between the fence and curb) or snow removal from public sidewalk(s) adjacent to the property.

(3) A fence, up to but not exceeding four feet (4') in allowable height may be placed up to the property line in the front yard and a street side yard.

(4) Fences up to but not exceeding the zoning district allowed height are allowed up to the property line within the limits of side and rear yards not adjacent to a street.

(5) Except as provided in 9-14-11B.3.a.(1) herein, fences up to but not exceeding the zoning district allowed height may be placed along the lot boundary adjacent to a street (street side yard or rear yard) when the fence maintains a minimum setback from the ultimate right-of-way of no less than fifteen feet (15').

The owner/operator shall remove the abandoned system at their expense. Removal of the system includes the entire structure, collector panels and related equipment from the property excluding foundations. Should the owner/operator fail to remove the system, the SES will be considered a public nuisance and will be abated in accordance with title 4, chapter 4, "Nuisances", of this code.

19. Screening: SESs that are visible from the public thoroughfare or adjacent properties will require screening in accordance to regulations for screening of mechanical units noted in section 9-10-4, "Specific Use Regulations", and in chapter 10, "Performance Standards", of this title. The need for and type of screening to be used shall be identified as part of the building permit, major or minor modification to a site plan or site plan permit submittal.

20. Nonconforming Systems: An SES that has been installed on or before the effective date of this section and is in active use and does not comply with any or all of the provisions of this section shall be considered a legal nonconforming structure and will be regulated by the provisions noted in section 9-3-4, "Nonconforming Buildings, Structures, Uses, Uses Of Land, Or Uses Of Buildings Or Structures", of this title.
