All horizontal distances for yard widths and lot and building
dimensions shall be measured along a horizontal plane from the appropriate
property line, edge of building, structure, storage area, parking
area, or other object. These distances shall not be measured by following
the topography of the land.
A.
Interior Height
Floor-to-ceiling height shall be measured from the top of the
floor finish to the bottom of the ceiling joists or, where there is
no ceiling, to the bottom of the roof rafters.
B.
Exterior Height of Primary Structures
The height of a primary structure building is the vertical distance
from the base point described in Subsection 19.202.2.B.1, below, to
the top of a building described in Subsection 19.202.2.B.2, below.
1.
Base Point
The base point used for building height measurement shall be
the base point that yields the greater building height. See Figure
19.202.2.B.1.
a.
Base point 1 is the elevation of the highest adjoining sidewalk
or ground surface within a 5-ft horizontal distance from the exterior
wall of the Building, when such sidewalk or ground surface is not
more than 10 ft above lowest grade.
b.
Base point 2 is 10 ft above lowest grade, when the sidewalk
or ground surface described for base point 1 is more than 10 ft above
lowest grade.

2.
Top of Building
The top of building shall be determined based on the specific
roof types listed below. See Figure 19.202.2.B.2.
a.
Flat roof: Measure to the top of the parapet or, if there is
no parapet, to the highest point of the roof. If a roof includes multiple
flat roofs at different elevations, measure to the top of the highest
parapet or highest point of the highest roof.
b.
Mansard roof: Measure to the deck line.
c.
Pitched, hipped, or gambrel roof where roof pitch is 12/12 or
less: Measure to the average height of the highest gable.
d.
Pitched or hipped roof with a pitch steeper than 12/12: Measure
to the highest point.
e.
Gambrel roof where both pitches are steeper than 12/12: Measure
to the highest point.
f.
Other roof shape, such as domed, vaulted, or pyramidal: Measure
to the highest point.
g.
Stepped or terraced building: Measure to the highest point of
any segment of the building.

C.
Exterior Height of Accessory Structures
The exterior height of an accessory structure is the vertical
distance above the average of the highest and lowest points of finished
grade, within a 10-ft horizontal Distance from the base of the building,
and the top of a building described in SubSection 19.202.B.2.
A.
Existing Trees
Existing trees are measured at a height 4.5 ft above the mean
ground level at the base of the tree, also sometimes referred to as
"diameter at breast height." Trees on slopes are measured from the
ground level on the lower side of the tree. If a tree splits into
multiple trunks below 4.5 ft above ground level, the diameter is measured
at its most narrow point below the split.
B.
New Trees
New trees are measured in caliper inches, which is the diameter
of the trunk 6 in above the mean ground level at the base of the tree.
Minimum required and maximum allowed dwelling unit density will
be calculated as described below, except that residential cluster
development on lands containing natural resource areas are subject
to the density calculations in Subsection 19.402.14.C. The purpose
of these calculations is to ensure that properties develop at densities
consistent with the densities in the Comprehensive Plan. The area
deductions for minimum required density allow properties to utilize
land that can be built upon. The area deductions for maximum allowed
density include sensitive lands where development should be avoided.
A.
Gross Area
The gross area of a lot is measured in sq ft and is determined
by a registered professional land surveyor or with data from the Clackamas
County Assessor's Office.
B.
Rounding
The results for minimum required and maximum allowed dwelling
unit density are rounded based on a fraction that is truncated to
2 numbers past the decimal point. For example, 3.4289 is truncated
to 3.42. Where a minimum density calculation results in a fraction
that is 0.50 or above, the fraction is rounded up to the next whole
number. Where a minimum density calculation results in a fraction
that is less than 0.50, the fraction is rounded down to the preceding
whole number. Where a maximum density calculation results in a fraction
that is less than 0.75, the fraction is rounded down to the preceding
whole number.
C.
Discrepancy between Minimum Required and Maximum Allowed Density
If the calculation results are that minimum density is equal
to maximum density, then the minimum required density is reduced by
one. If the calculation results are that minimum density is larger
than maximum density, then the minimum required density is reduced
to one less than the maximum. If the calculation results are that
the maximum density calculation is equal to zero, then the minimum
density is one.

Deductions to Calculate Net Area
The following areas, measured in sq ft, are subtracted from
the gross area to determine the net area. The net area calculation
is rounded to the nearest whole number.
a.
Floodways, as determined by Federal Emergency Management Agency
flood maps.
b.
Right-of-way dedications for new right-of-way or expansion of existing rights-of-way, as required in Chapter 19.700.
c.
Open space or parkland that will be publically owned or open
space owned in common by owners within the residential development.

Maximum Density

Deductions to Calculate Net Area
The following areas, measured in sq ft, are subtracted from
the gross area to determine the net area. The net area calculation
is rounded to the nearest whole number.
a.
1% Annual Chance Flood areas (also called the 100-Year Floodplain),
as determined by Federal Emergency Management Agency flood maps.
b.
Right-of-way dedications for new right-of-way or expansion of existing rights-of-way, as required in Chapter 19.700.
c.
Open space or parkland that will be publicly-owned or open space
owned in common by owners within the residential development.
d.
Naturally occurring slopes in excess of 25%.
e.
Man-made slopes (grades that are the result of human activity
rather than natural causes) in excess of 25% with both a horizontal
measure over 40 ft and an elevation change more than 10 ft over that
horizontal distance.
The area of a building façade is the sum of all wall
areas above grade that are visible on one side of a building. The
following areas are excluded: roof areas; the wall area of a horizontal
or vertical offset that is perpendicular to the primary orientation
of the façade; and gable ends below the ridge of the roof and
above the eave line. The wall area of a dormer is not exempt.
