The purpose of this Chapter is to establish rules and regulations
for setback measurement, yard areas, and encroachments. These provisions,
in conjunction with other applicable provisions of this Title, are
intended to ensure open areas around primary structures, maintain
clear visibility for traffic safety and pedestrian access, buffer
between property and land uses, and establish natural and visual light
and air space privacy, landscaping, and recreation.
(Ord. 1501 § 1, 2011)
Terms unique to this Chapter are listed in Section 17.100.060 (Universal Definitions).
(Ord. 1501 § 1, 2011)
The following are the types of lots found within the City of

ownership having frontage upon a street. See Figure 17.44.030-1 (Lot
Types and Yard Areas) for illustration of lot types.
A.
"Corner
lot" means a lot bounded by two or more abutting and intersecting
street lines.
B.
"Double
frontage lot" means an interior lot bounded by two or more abutting
street lines that do not intersect.
C.
"Flag
lot" means a lot connected to a street by an access corridor such
as an alley, narrow private drive, or access easement.
D.
"Interior
lot" means a lot which is not a corner lot and has only one street
frontage.
E.
"Key
lot" means the first interior lot to the rear of a reversed corner
lot.

"Reverse
corner lot" means a corner lot in which the rear property line abuts
the front yard area of an adjoining interior lot (as opposed to the
rear yard of another corner lot).
(Ord. 1501 § 1, 2011)
A.
A yard
is an area between a property line and a building or structure, unobstructed
and unoccupied from the ground upward. There are three general types
of yards as follows:
1.
Front
Yard. An area extending across the full width of the lot between the
front lot line and the required setback.
2.
Rear
Yard. An area extending the full width of the lot between a rear lot
line and the required setback.
3.
Side
Yard. An area extending from the front yard to the rear yard between
the nearest side lot line and the required setback.
B.
A required
yard area is the yard space between the property line and the minimum
setback as required by this Title.
C.
An
actual yard is the yard space between the property line and the nearest
structure located outside of the required setback area.

(Ord. 1501 § 1, 2011)
A.
Setback
distances shall be measured at right angles from the designated property
line (e.g., front, interior side, street-side, rear) and the setback
line shall be drawn parallel to the designated property line at the
required setback distance. Designated property lines are determined
as follows:
1.
Front
Property Line. The front property line shall be the narrowest property
line which abuts a public street (see Figure 17.44.050-1). For corner
lots, the front property line shall be the shortest street frontage,
regardless of where the front door is located. In the case of a flag
lot, it shall be the property line that abuts the access corridor
(see Figure 17.44.050-2).
2.
Rear
Property Line. The rear property shall be the property line which
is opposite and most distant from the front property line and most
parallel to the front property line. See Figures 17.44.050-1 and -2
for examples of a common rear property line.
3.
Side
Property Line. The side property line shall be those property lines
that are not the front or rear property lines.
4.
Street
Side Property Line. The street side property line shall be that which
abuts a public street.
