Sign Area

To determine the proposed sign area, both sides/sign faces are to be included in the calculation. For example, if each side or sign face measures 4 sq. ft., the total sign area is 8 sq. ft.

Minor deviations from the dimensional standards for pedestal signs, except for maximum sign height, may be approved by the Planning Official if he/she concludes that the resulting sign has a clear and substantial visual linkage to the ground.

Design Criteria

SIGN BASE: The base of the sign must be done in landscape construction materials such as brick, stucco, stonework, textured wood, tile or textured concrete or materials that are harmonious with the character of the primary structures on the subject property and subject to Planning Official approval. No visible gap shall be allowed between the sign base and the finished grade.

SIGN FACE: The color, shape, material, lettering, and other architectural details of the sign face must be harmonious with the character of the primary structures.

Minor Deviations

Minor deviations from the dimensional standards for monument signs, except for maximum sign height, may be approved by the Planning Official if he/she concludes that the resulting sign does not significantly change the relative proportion of the sign base to the sign face.

Plate 32 Affordable Housing Incentives – Multifamily

112.20.2 Defined Affordable Housing Incentives – Density Bonus:

In use zones where the number of dwelling units allowed on the subject property is determined by dividing the lot size by the required minimum lot area per unit, two (2) bonus units may be constructed for each affordable housing unit provided (see Example 1). In areas where the density allowed on the subject property is expressed as a floor area ratio (F.A.R.), bonuses will be calculated as an equivalent FAR bonus (see Example 2). These examples are for properties that do not contain a wetland, stream, minor lake or their buffers. For properties that contain a wetland, stream, minor lake or their buffers, the base density allowed shall be established using the maximum development potential calculation in KZC 90.170. (Ord. 4551 § 4, 2017)

Example 1 – Density Bonus

Property Size (Net Acres)

3 Acres

Zoned Density

2,400 square feet of land area required per unit

Base Density Allowed

(3 Acres x 43,560 sq. ft. per acre)/2,400 sq. ft. per unit = 54.45 units

(Rounds to 54 units)

Proposed Number of Affordable Housing Units

5 Units

Proposed Bonus Units

5 Units x 2 = 10 Units

Total Units Allowed

54 Base Units + 10 Bonus Units = 64 Units (including 5 Affordable Housing Units)

Maximum Bonus Units (25% of Base Density)

54 Units x 0.25 = 13.5 Units (Rounds to 13)*

*Note: If seven affordable housing units were provided, only 13 bonus units (instead of 14 bonus units) could be achieved through the defined affordable housing incentives process due to the maximum bonus provision (KZC 112.20(2)(c)) An applicant may apply through the additional affordable housing incentives (non-defined) process (KZC 112.25) for a larger number of bonus units.

Example 2 – FAR Bonus

Property Size (Net Acres)

1 Acre

Zoned Density

2.5 maximum Floor Area Ratio (F.A.R.)

Base Density Allowed

(1 Acre x 43,560 sq. ft. per acre) x 2.5 F.A.R. = 108,900 square feet

Proposed Number and Size of Affordable Housing Units

6 Units each containing 1,200 square feet of gross floor area

Affordable Housing Floor Area

6 Units x 1,200 square feet per unit = 7,200 square feet

Proposed Bonus Floor Area

7,200 square feet x 2 = 14,400 square feet*

Total Square Footage Allowed

108,900 Base Square Feet + 14,400 Bonus Square Feet = 123,300 square feet (including 6 Affordable Housing Units)

Maximum Bonus Floor Area (25% of Base FAR)

108,900 square feet x 0.25 = 27,225 square feet

*Note: The 14,400 square feet of bonus floor area can be used on the subject property as the applicant feels best meets project needs.

Plate 47 Establishing Average Pier Length/Navigation Line

Plate 47 is intended to clarify how the average pier length of an adjacent shoreline parcel influences the length of a proposed pier. The plate illustrates the location of several single-family piers located along the shoreline of Lake Washington. The image identifies the maximum length of 150 feet allowed under KZC 83.270(4), and the average lakeward extent of the piers along this section of the shoreline. The established line of navigation runs along the waterward side of the piers. By determining the average length of the neighboring piers, a property can identify the length of a pier that may be proposed that will be consistent with the length standards of KZC 83.270 and Shoreline Area Policy SA-11.1 in the Comprehensive Plan.

(Ord. 4701 § 1, 2020)

Plate 48A How to Determine the Allowable Length of a Single-Family Pier (KZC 83.270(4))

Parcel “J” needs to establish the allowable length a pier may extend under the development regulations of KZC 83.270. Since the 150 foot measurement from the OHWM exceeds the average lakeward extent of the adjacent neighboring piers, the lesser applies. Parcel “J” may propose a pier length as shown, aligning with the average lakeward extent of the adjacent neighboring piers. The pier is subject to all other dimensional standards, including but not limited to width, area, and height.

A proposal beyond the average lakeward extent line would require the applicant identify the length will not have an adverse impact on navigation and the length is necessary due to inadequate water depth.

A proposed pier beyond the 150 foot measurement would be subject to a shoreline variance.

Plate 48B How to Determine the Maximum Length a Pier May Extend Beyond Existing Adjacent Piers (KZC 83.270(4))

An additional 10% of length on the subject property may be added based on the average lakeward extent of the existing adjacent neighboring piers. In this example, the average lakeward extent establishes an allowable length of 130 feet for the subject property. The parcel may propose up to 13.0 feet of additional length if necessary to achieve water depth
