This Chapter expands upon the zoning district development standards of Article 2 by addressing additional details of site planning, project design, and the operation of land uses. The intent of these standards is to ensure that proposed development is compatible with existing and future development on neighboring properties, and produces an environment of stable and desirable character, consistent with the General Plan and any applicable specific plan.
(Ord. 930, § 2, passed 06-12-2017)
18.30.020 - Applicability
The requirements of this Chapter shall apply to all proposed development and new land uses, except as specified in Chapter 18.90 (Nonconforming Uses, Structures, and Parcels), and shall be considered in combination with the standards for the applicable zoning district in Article 2 (Zoning Districts and Allowable Land Uses) and those in Article 4 (Standards for Specific Land Uses). If there is a conflict, the standards in Article 4 shall control.
(Ord. 930, § 2, passed 06-12-2017)
18.30.050 - Fences, Walls, and Screening
A. Applicability. The requirements of this Section apply to all fences and walls unless otherwise stated.
1. Fences or walls in flood hazard area. A fence or wall in an area subject to flooding identified on a Federal Flood Insurance Rate Map (FIRM) on file in the Department shall require a Building Permit, and shall comply with all requirements of the Director of Public Works in addition to the requirements of this Section.
2. Exemptions. These regulations do not apply to fences or walls required by regulations of a State or Federal agency, or by the City for reasons of public safety.
B. Height limits.
1. General height limit. Each fence, wall, and hedge shall comply with the height limits shown in Table 3-1.
|
Location |
Maximum Height |
|---|---|

Within front or street side setback |
Open fence: 6 ft (open fencing must be of a minimum 4-inch wire mesh or equivalent). View-obscuring fence: 42 inches (3 1/2 ft) within a traffic safety visibility area (see § 18.30.060(E)), 6 ft elsewhere. Trellises, arbors and similar entry features are not permitted within a traffic safety visibility area, but are allowed up to 8 ft elsewhere (a height greater than 6 ft requires a Building Permit). |
|
Within interior side or rear setback |
8 ft with Minor Use Permit approval; 6 ft otherwise. |
|
Outside of required setbacks |
8 ft (a height greater than 6 ft requires a Building Permit). |
2. Requirements for increased height. Where Table 3-1 allows increased fence height with Minor Use Permit approval, the approval shall be subject to the following requirements:
a. Each fence shall comply with the traffic safety visibility area requirements in § 18.30.060(E) (Height limits and exceptions - Height limit at street corners).
b. The review authority may require conditions to address aesthetic issues and neighborhood concerns.

18.30.100 - Setback Requirements and Exceptions
A. Purpose. This Section provides standards for the location, required size, and allowable uses of front, side, and rear setbacks. Setback standards provide open areas around structures for: visibility and traffic safety; access to and around structures; access to natural light, ventilation and direct sunlight; separation between potentially conflicting activities; and space for privacy, landscaping and recreation.
B. Setback requirements.
1. Minimum setbacks for all structures. Each structure shall comply with the front, interior side, street side, and rear setback requirements of the applicable zoning district, except:
a. Where a different setback requirement is established for a specific land use by Article 4 (Standards for Specific Land Uses);
b. Where a different setback requirement is established by Article 5 (Resource Protection); and
c. As otherwise provided by this Section.
No portion of any structure, including eaves or roof overhangs, shall extend beyond a property line, or into an access easement or street right-of-way, except as provided by this Section.
2. Exemptions from setback requirements. The minimum setback requirements of this Development Code do not apply to the following (please see Table 3-2 for additional details):
a. A projection into a required setback allowed by Subsection (E) of this Section;
b. A fence or wall 6 feet or less in height, when located within a front or street side setback;
c. A fence or wall 42 inches in height or less within a front or street side setback when located in the traffic visibility area required by § 18.30.060(E) (Height limit at street corners);
d. A deck, earthwork, step, terrace, and other site design element that is placed directly upon grade and does not exceed a height of 30 inches above the surrounding grade at any point;
e. A sign in compliance with Chapter 18.38 (Signs);
f. A retaining wall less than 30 inches in height above finished grade. Any embankment to be retained that is over 48 inches in height shall be benched so that no individual retaining wall exceeds a height of 36 inches, and each bench is a minimum width of 36 inches; and
g. An arbor or trellis (i.e., gateway) 8 feet or less in height.
C. Measurement of setbacks. Setbacks shall be measured and applied as follows, except that the Director may require different setback measurement methods where the Director determines that unusual parcel configuration makes the following infeasible or ineffective. See Figure 3-4.
Figure 3-4 - Location and Measurement of Setbacks
1. Front setback. A front setback shall be measured at right angles from the nearest point on the front property line of the parcel (or edge of access easement on a private street) to the nearest point of the wall of the structure, except as provided in following Subsections (C)(1)(a) through (e) of this Section. The front property line is the narrowest dimension of a lot adjacent to a street.
a. Averaging. In a residential zone where 50% or more of the parcels on the same block and on the same side of the street are developed with buildings, the front setback required for the applicable zoning may be reduced to the average depth of the front setbacks of the developed parcels.
b. Mapped street with future improvements. If the City has established a plan that identifies a right-of-way for the future construction of a new street or the widening of an existing street, a required front or street side setback shall be measured from the plan line.
c. Infill development within previously approved project. Where the City has established specific setback requirements for individual vacant parcels through the approval of a specific plan, subdivision map, or other entitlement, those setbacks shall apply to continuing development within the approved project instead of the setbacks required by this Development Code.
d. Flag lot. For a parcel with a fee ownership strip extending from a street or right-of-way to the building area of the parcel, the front setback shall be measured from the nearest point of the wall of the structure to the point where the access strip meets the bulk of the parcel; establishing a setback line parallel to the lot line nearest to the public street or right-of-way.
e. Corner lot. The front setback shall be measured from the nearest point of the wall of the structure to the nearest point of the most narrow street frontage property line. If the property lines on both street frontages are of the same length, the property line to be used for the front setback measurement shall be determined by the Director.
2. Side setback. The side setback shall be measured at right angles from the nearest point on the side property line of the parcel to the nearest point of the wall of the structure; establishing a setback line parallel to the side property line, which extends between the front and rear setbacks.
3. Street side setback. The side setback on the street side of a corner parcel shall be measured from the nearest point on the side property line bounding the street, or the edge of an easement for a private road, or the inside edge of the sidewalk whichever results in the greatest setback from the existing or future roadway.
4. Rear setback. The rear setback shall be measured at right angles from the nearest point on the rear property line to the nearest line of the structure, establishing a setback line parallel to the rear property line.
a. The Director shall determine the location of the required rear setback on a double-frontage parcel.
b. Where a parcel has no rear lot line because its side lot lines converge to a point, an assumed line 5 feet long within the parcel, parallel to, and at a maximum distance from the front lot line, shall be deemed to be the rear lot line for the purpose of determining the depth of the required rear setback.
D. Limitations on the use of setbacks.
1. Structures. A required setback area shall not be occupied by a structure other than those identified by Subsection (B)(2) of this Section as being exempt from the setback requirements of this Chapter.
2. Storage. No front or street side setback shall be used for the accumulation, placement or storage of vehicles, large motor vehicles, nonmotorized vehicles (as defined in § 10.02.010), building materials, scrap, junk or machinery except for the following:
a. Vehicles, not in excess of 1-ton capacity, regularly in use, that are parked within a designated driveway;
b. Building materials and construction trailers required for construction on the parcel, immediately before and during a construction project which has a valid Building Permit in force; and/or
c. Trailers, large motor vehicles and nonmotorized vehicles stored or parked in a front or street side setback area in any nonresidential zoning district where authorized through Minor Use Permit approval (§ 18.71.060).
3. Parking. See § 18.36.090(A). (Parking Design and Development Standards - Location of parking).
4. Mechanical and utility equipment. See Subsection (F)(5) of this Section (Setback requirements for specific structures - Mechanical equipment).
5. Exceptions to setback requirements. See Subsection (B)(2) of this Section for structures that are exempt from setback requirements.
E. Allowed projections into setbacks. An architectural feature attached to a primary structure may extend beyond the wall of the structure and into a required front, side, or rear setback in compliance with Table 3-2. See also Subsection (B)(2) of this Section and Figure 3-5.
