Plate 12
PEDESTAL SIGNS

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.

Plate 13
MONUMENT SIGNS

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 13A
POLE SIGNS

HEIGHT OF SIGN SHALL NOT EXCEED 20 FEET ABOVE AVERAGE

COMPOSED OF TWO CHIEF ELEMENTS: THE SIGN FACE AND THE SIGN
POLE(S) OR PYLON(S) WHICH CONNECT(S) THE SIGN FACE TO THE GROUND.

WETLAND FIELD DATA FORM

WETLAND FIELD DATA FORM

BEGIN BY CHECKING ANY OF THE FOLLOWING (a. – e.) THAT APPLY:

a.  The wetland is contiguous to Lake Washington;

b.  The wetland contains at least 1/4 acre of organic soils, such as peat bogs or mucky soils;

c.  The wetland is equal to or greater than 10 acres in size and having three or more wetland classes, as defined by the U.S. Fish & Wildlife Service (Cowardin et al., 1979), one of which is open water;

d.  The wetland has significant habitat value to state or federally listed threatened or endangered wildlife species; or

e.  The wetland contains state or federally listed threatened or endangered plant species.

IF ANY OF THE CRITERIA LISTED ABOVE ARE MET, THEN THE WETLAND IS CONSIDERED TO BE TYPE 1. IF THAT IS THE CASE, PLEASE CONTINUE TO COMPLETE THE ENTIRE FORM, BUT DO NOT ASSIGN POINTS.

IF THE WETLAND DOES NOT MEET THE CRITERIA LISTED ABOVE FOR TYPE 1, COMPLETE THE ENTIRE FORM, USING THE ASSIGNED POINTS TO DETERMINE IF IT IS A TYPE 2 OR TYPE 3 WETLAND.

Type 2 wetlands typically have at least two wetland vegetation classes, are at least partially surrounded by buffers of native vegetation, connected by surface water flow (perennial or intermittent) to other wetlands or streams, and contain or are associated with forested habitat.

1.  Total wetland area

Estimate wetland area and score from choices Acres Point Value  Points   

      >20.00 = 6

      10-19.99 = 5

      5-9.99 = 4

      1-4.99 = 3

      0.1-0.99 = 2

      <0.1 = 1

2.  Wetland classes: Determine the number of wetland classes that qualify, and score according to the table.

Open Water: if the area of open water is >1/3 acre or >10% of the total wetland area

7

Forested: if the area of forested class is >1/2 acre or >10% of the total wetland area

5

=

10

3.  Plant species diversity.

      For all wetland classes which qualified in 2 above, count the number of different plant species and score according to the table below. You do not have to name them.

      e.g., if a wetland has an aquatic bed class with 3 species, and emergent class with 4 species and a scrub-shrub class with 2 species, you would circle 2, 2, and 1 in the second column (below).

Class # of Species Point Value Class # of Species Point Value

Aquatic Bed 1-2 = 1 Scrub-Shrub 1-2 = 1

      3 = 2 3-4 = 2

      >3 = 3 >4 = 3

Emergent 1-2 = 1 Forested 1-2 = 1

      3-4 = 2 3-4 = 2

      >4 = 3 >4 = 3

4.  Structural diversity.

      If the wetland has a forested class, add 1 point for each of the following attributes present:

      Trees >50' tall = 1

      Trees 20' to 49' tall = 1

      shrubs = 1

      Herbaceous ground cover = 1

5.  Interspection between wetland classes.

      Decide from the diagrams below whether interspection between wetland classes is high, moderate, low or none

      3 = High

      2 = Moderate

      1 = Low

      0 = None

6.  Habitat features

      Add points associated with each habitat feature listed:

Is there evidence of current use by beavers? = 3

Is a heron rookery located within 300'? = 2

Are raptor nest(s) located within 300'? = 1

Are there at least 2 standing dead trees (snags) per acre? = 1

Are there any other perches (wires, poles, or posts)? = 1

Are there at least 3 downed logs per acre? = 1

7.  Connection to streams

      Is the wetland connected at any time of the year via surface water? (score one answer only)

Is the wetland connected at any time of the year via surface water?

To a perennial stream or a seasonal stream with fish = 5

To a seasonal stream without fish = 3

Is not connected to any stream = 0

8.  Buffers

      Step 1: Estimate (to the nearest 5%) the percentage of each buffer or land-use type (below) that adjoins the wetland boundary. Then multiply these percentages by the factor(s) below and enter result in the column to the right.

      % of Buffer Step 1 Width Factor Step 2

Roads, buildings or parking lots    % X 0 =           =    

Lawn, grazed pasture, vineyards or annual crops    % X 1 =           =    

Ungrazed grassland or orchards    % X 2 =           =    

Open water or native grasslands    % X 3 =           =    

Forest or shrub    % X 4 =           =    

      Add buffer total      

      Step 2: Multiply result(s) of step 1:

      By 1 if buffer width is 25-50'

      By 2 if buffer width is 50-100'

      By 3 if buffer width is >100'

      Enter results and add subscores

      Step 3: Score points according to the following table:

      Buffer Total

      900-1200 = 4

      600-899 = 3

      300-599 = 2

      100-299 = 1

9.  Connection to other habitat areas:

Is there a riparian corridor to other wetlands within 0.25 of a mile, or a corridor >100' wide with
good forest or shrub cover to any other habitat area? = 5

Is there a narrow corridor <100' wide with good cover or a wide corridor >100' wide with low cover
to any other habitat area? = 3

Is there a narrow corridor <100' wide with low cover or a significant habitat area within 0.25 mile
but no corridor? = 1

Is the wetland and buffer completely isolated by development and/or cultivated agricultural land? = 0

10. Scoring

      Add the scores to get a total: ______

      Question: Is the total greater than or equal to 22 points?

      Answer:

      Yes = Type 2

      No = Type 3

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 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 (FAR), 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 90.135.
