18.40.020 Purpose

These standards shall ensure that new and altered uses and development will produce an urban environment of stable, desirable character which is harmonious with existing development and consistent with the Comprehensive Plan.

(Ord. 5517 §1, 1995).

18.40.040 Applicability

All new construction, grading, and additions and all modifications to an existing structure in excess of twenty-five (25) percent of the structure floor area, shall be subject to the standards set forth in this Chapter. See Non-conforming, Chapter 18.37.) All continuing operations and uses shall be subject to and conform to the Protection Standards of this Chapter.

(Ord. 6562 §4, 2008; Ord. 5830 §45, 1998; Ord. 5517 §1, 1995).

18.40.060 General standards

These standards apply to more than one (1) land use district and are therefore combined in this Chapter. These standards are to be considered in addition to standards and design guidelines located in specific land use district chapters.

A. Required Building Site.

1. Building Site--Number of Buildings. Every main building hereafter erected shall be located on a legal lot of record as provided for in this title. There shall be no more than one (1) main building on any one (1) lot in the R-4, R 4-8, and R 6-12 use districts.

2. Lot or Building Site--Reduction. No lot or parcel of land now existing or hereafter established shall be so reduced or diminished that yards, open space, width or total lot area be made smaller than the minimum required by this title; nor shall any existing lot or parcel of land that is now smaller than the minimum required by this title be further reduced or diminished in any manner.

B. Clear Sight Triangle. (See Clear Sight Triangle definition.)

1. All corner building sites located in use districts that require a front and side yard shall maintain a clear sight triangle at the intersection of the street rights-of-way for the purpose of traffic safety. Such building, other structures, and landscaping shall conform to those standards set forth in the Public Works and Engineering Standards of the City. No building, structure, object or growth over two and one-half (2.5) to ten (10) feet in height, measured from the street centerlines of the intersecting streets, shall be allowed within this triangle.

2. Absent an Engineering Standard, one angle of this triangle shall be formed by the intersecting street rights-of-way and the sides of the triangle measured along the property lines from said angle shall be twenty (20) feet in length; the third side of such triangle shall be a straight line connecting the ends of the two (2) aforementioned lines.

3. The Public Works Director may alter the clear sight triangle. Such alteration is contingent on unusual site topography, proposed site design features, and other unique circumstances pertaining solely to the site and surrounding properties. The Public Works Director or designee shall make written findings that the alteration does not constitute a traffic or pedestrian safety hazard.

4. Street lights, power poles, traffic signs, or similar street fixtures less than one (1) foot wide or other objects above ten (10) feet in height above the adjacent street elevation shall be allowed in the clear sight triangle unless the Public Works Director determines that, individually or cumulatively, they would pose a public safety hazard. The Public Works Director may authorize other objects in the clear sight triangle which do not comply with this standard upon determining that they would not pose a risk to public safety.

FIGURE 40-1

C. Fences/Hedges, Walls and Site Perimeter Grading. It shall be the responsibility of property owners to ensure fences are within property lines. "Fences" as used in this section includes walls and similar above-grade unenclosed structures forming a continuous or nearly continuous line or row exceeding six feet in length. Also see definition, OMC 18.02.180.F. For this section only, any portion of a special purpose lot, tract or parcel, such as a stormwater or tree tract, which is within ten feet of any public street right-of-way shall be a "front yard," and all other yards shall be defined as if such tract were a buildable lot.

1. Fences, when located within a required yard, shall not exceed the following height limits:

a. Front yard = 48" (4’-0");

b. Side yards = 72" (6’-0");

c. Rear yards = 72" (6’-0");

d. Clear Sight Triangle = 30" (2’-6").

For purposes of this section, a front yard shall not exceed ten feet in depth, regardless of any other provision found in this Title.

2. Fence height is measured to the top of the fence, excluding posts. Point of ground measurement shall be the high point of the adjacent final grade.

3. Fences, walls, and hedges are permitted within all yard areas provided that regardless of yard requirements, no closed gate, garage door, bollard or other feature shall obstruct a driveway or other motor vehicle private ingress within twenty (20) feet of a street right-of-way nor obstruct automobile views exiting driveways and alleys (see clear vision triangle). This 20-foot requirement is not applicable within the downtown exempt parking area as illustrated at Figure 38-2. Additional exceptions may be granted in accordance with OMC 18.38.220(A)(2).

4. Front yard fences, of common areas, such as tree, open space, park, and stormwater tracts, must be a minimum of twenty-five (25) percent unobstructed, i.e., must provide for visibility through the fence.

5. Fence pillars, posts, and similar features may project a maximum of two (2) feet above maximum fence height.

6. Site Perimeter Grading. Within required yard areas, no single retaining wall (nor combination of walls within five horizontal feet) shall exceed a height of 30 inches as measured from the lowest adjacent grade, nor shall any modification of grades or combination of retaining walls result in grade changes exceeding 30 inches within five feet of a property line nor 60 inches within 10 feet of an existing or proposed property line.

7. An administrative exception may be approved by the Department to exceed maximum fence height and other provisions of these standards under where all of the following conditions exist.

a. Variation of existing grade on either side of the fence results in a fence lower than the maximum height as measured from the highest point of grade within five (5) feet of either side of the fence; or other special circumstances relating to the size, shape, topography, location, or surroundings of the subject property warrant an exception to permit a fence comparable with use rights and privileges permitted to other properties in the vicinity and in the zone in which the subject property is located;

b. The special conditions and circumstances do not result from the actions of the applicant;

c. Granting of the exception will not constitute a grant of special privilege inconsistent with the limitation upon uses of other properties in the vicinity and zone in which the property is located;

d. The granting of the exception will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and zone in which subject property is situated; and

e. The exception is the minimum necessary to provide the rights and privileges described above.

Applications for additional fence height or other exceptions shall include a letter or form explaining the exception sought and its purpose of; and fence illustrations and plan drawing that depicts proposed fence location and height, other structures, landscaping, and proposed grades in relation to existing grades.

[NOTE: A building permit is required for all fences exceeding six (6) feet in height. Fences and hedges may exceed maximum heights if located outside of required yards. But see Design Guidelines.]

8. Hedges. Hedges are allowed in all required yard areas subject to the following maximum height limits:

a. Front yard = 48" (4’0")

b. Side yard = Unlimited

c. Rear yard = Unlimited

[Note: Clear Sight Triangle = 30" (2’-6"), see Section 18.40.060.(C)]

9. Barbed and/or razor wire fences. No person or persons being the owner of or agent for or in possession and control of any property within the city limits shall construct or permit to exist any fence around or in front of such premises, consisting wholly or partially of barbed and/or razor wire, except to provide security at a government-owned property or privately owned utility where security for the property is mandated by law; provided that the provisions of this section shall only extend to fences that are within ten (10) feet of a street or alley or other public place within the City.

9. Electric fences. It is unlawful to erect or install or maintain any electric fence within the city limits. "Electric fence" means any fence with above-ground electric conductors carrying electric current supplied by batteries, commercial power or any other source of electricity, erected for the purpose of retaining or excluding any animals, livestock, or persons.

D. Lighting. All display and flood lighting shall be constructed and used so as not to unduly illuminate the surrounding properties and not to create a traffic hazard.

E. Outdoor Storage.

1. Except as provided in the underlying district, there shall be no outdoor storage of goods or materials, and there shall be no warehousing or indoor storage of goods or materials beyond that normally incidental to the uses permitted in each underlying district. Permitted outdoor storage must be screened from view of any public way.

2. Materials covered by buildings with roofs but without sides shall be considered outdoor storage and shall be subject to the screening provisions of this section. This provision shall not apply to display of new or used motor vehicles or watercraft where such activities are an integral part of an automobile or watercraft dealership. Refuse may be stored in cans outdoors, provided that they are enclosed in a screened enclosure area.

3. Storage in residential areas shall comply with the same requirements as those specified for business establishments and shall, in addition, comply with the following:

a. Motor vehicles, appliances, and any other mechanical equipment which is no longer operable or licensed shall not be stored outside for a period exceeding thirty (30) days;

b. Operable motor vehicles, boats, trailers, recreational vehicles and the like may be stored on the premises provided that they do not obstruct the use of public right-of-way or interfere with traffic visibility, especially the visibility of and at intersections of streets. Vehicles, boats, and the like, so stored shall not be used for living quarters. The storage of boats with a beam exceeding eight (8) feet may be permitted only if it is determined by the Hearing Examiner that such storage will not be detrimental to surrounding property or the neighborhood. In no event shall such vehicles, boats and the like be stored within less than five (5) feet of any side or rear property line without written approval of the occupant of the adjoining property.

4. Storage in or on the public right-of-way is prohibited. All vehicles, boats, trailers, recreational vehicles, household and business equipment, landscape material and any other personal items shall not be placed within a public right-of-way longer than twenty-four (24) hours. Stored item(s) shall be tagged by the police and a warning issued to remove within seventy-two (72) hours. Failure to do so will result in removal by the city at the owners expense. (Also see RCW 46.55.085.)

F. Pleasure Boat Storage.

1. Private pleasure boats shall be allowed to moor in any use district and such moorage, exclusive of yacht clubs, marinas and other commercial moorage facilities shall be subject to the following requirements:

2. The height of any covered boat house shall not exceed sixteen (16) feet above the ordinary water level.

3. In the absence of filed tariffs, rules or regulations, published policies or contractual agreement, the cost of constructing new facilities underground or relocating existing aerial facilities underground may be financed by any method authorized by state law.

H. Yards.

1. In addition to the following, yard regulations found in Section 18.04.060(B) (Accessory Structures) apply to all building sites in all use districts of the city.

2. Yards/Setbacks.

a. The required setback area shall be parallel to the structure requiring a setback. Setback width shall be measured from the outermost edge of the building foundation to the closest point of the parallel (or nearly parallel) adjoining lot line. In the event of a planned unit development or binding site plan, such development shall meet all Uniform Building Code separation requirements. (See Figure 40-4.)

b. A required yard area shall be kept free of any building or structure taller than thirty (30) inches, except that a building or projection shall be allowed as provided below:

i. Cornices, window sills, bay windows, flues and chimneys, planters, and eaves of roofs may project two (2) feet into the required yard area.

FIGURE 40-5

3. Use of Yard by Another Building. No yard or other open space required by this chapter for any building shall be considered as a yard or other open space for any other building; nor shall any yard or open space on one building site be considered as a yard or open space for a building on any other building site.

I. Minimum Street Frontage.

1. Each lot, other than in townhouse, cottage and co-housing projects, shall have a minimum of thirty (30) feet of frontage on a public or private street. With respect to binding site plans, this requirement shall apply to the entirety of the binding site plan and not to each individual site or lot. The Director may allow the street frontage to be reduced or eliminated to the minimum extent necessary to enable access to property where public street access is not feasible for such reasons, including but not limited to, physical site conditions or preexisting development or to protect environmentally Critical Areas.

FIGURE 4-2

2. Subdivisions, short subdivisions, binding site plans, and lot line adjustments creating flag lots (with street frontages of less than thirty (30) feet) are subject to the following conditions.

a. The project shall be designed to minimize the creation of flag lots.

b. Adjoining flag lots shall share a common driveway wherever possible.
