comments and In house Staff Review

CONDITIONS ASSOCIATED WITH
DEVELOPMENT STANDARDS TABLE FOR
SINGLE FAMILY RESIDENTIAL ZONING DESIGNATIONS
1. a. Phasing, shadow platting, or land
reserves may be used to satisfy the
minimum density requirements if the
applicant can demonstrate that the current
development would not preclude the
provision of adequate access and
infrastructure to future development and
would allow for the eventual satisfaction of
minimum density requirements through
future development.
b. In the event the applicant can show
that the minimum density cannot be
achieved due to lot configuration, lack of
access, environmental or physical
constraints, minimum density requirements
may be waived by the Reviewing Official.
2. Use -related provisions are not
variable. Use -related provisions that are
not eligible for a variance include:
building size, units per structure/lot, or
densities. Unless bonus size or density
provisions are specifically authorized,
the modification of building size, units
per structure, or densities requires a
legislative change in the code provisions
and/or a Comprehensive Plan
amendment/rezone.
3. Clustering is allowed to meet
objectives such as preserving significant
natural features, providing neighborhood
open space, or facilitating the provision of
sewer service. Within designated urban
separators clustering is required, consistent
with the provision of Section 4-3-110,
Urban Separator Overlay Re lations.
a. .
d. a. The maximum net density
requirement shall not be exceeded
except within Urban Separators a
density bonsus may be gg ted allowing
the total denser to achieve 1 dwelling
unitper oss acre for Rrojects that meet
the followingcriteria.
i. Provision of native vegetation cover
on 65% of the gross land area
including both the area within and
outside the open saace corridor with
either existing or new vegetative
cover, and at least one of the
following additional criteria.
1) Enhancement of wetlands is
provided at a ratio of one-half acre
enhanced for one acre delineated
within the Urban Separator pursuant
to Section 4-3-OSOM 12b.
Evaluation Criteria, and Section 4-3-
050M 12.c. Wetlands Chosen for
Enhancement. Enhancement
proposed for a density bonus may
not also be used for a mitigation for
other wetland alterations.
b) LegAl Non -conforming uses are
removed from the site and/or
brought into conformance with
Renton standards.
cc) Natural surface pedestrian and/or
equestrian trails, with public access,

are provided as part of an adopted
trail system or, where there is no
planned trail system, in a
configuration approved by the
Reviewing Official.
In the absence of either wetlands or
legal non -conforming uses on the site,
public access and trails shall be
required to the satisfaction of the
Reviewing Official.
b. The area of individual lots shall not be
less than 10,000 sq. ft.
d. Eaves: Eaves and cornices may
project up to 24" into any required
setback.
5. In order to be considered detached, a
structure must be sited a minimum of 6'
from any residential structure.
6. A front yard setback of less than 20' is
allowed if equal to or greater than the
average of the front yard setback of the
existing, abutting primary structures;
however, in no case shall a minimum
setback of less than 20' be allowed for
garages which access from the front yard
strect(s).
C.
7. For pre-existing legal lots having less
C than the minimum lot width required by this
Section, the following chart shall apply for
determining the required minimum side yard
width along a street:
4. Allowed Projections into Setbacks:
a. Fireplace Structures, Windows:
Fireplace structures, bay or garden
windows, enclosed stair landings,
and similar structures as Zoning
Administrator may project 24" into
any setback; provided, such
projections are:
i) Limited to 2 per fagade.
ii) Not wider than 10'.
b. Fences: See RMC 4-4-040.
c. Steps and Decks: Uncovered steps
and decks not exceeding 18" above
the finished grade may project to any
property line. Uncovered steps and
decks having no roof covering and
not exceeding 42" high may be built
within the front yard setback.

However, in no case shall a structure
over 42" in height intrude into the 20'
clear vision area defined in RMC 4-11-

8. 1n no case shall building height exceed
the maximum allowed by the Airport
Related Height and Use Restrictions, for
uses located within the Federal Aviation
Administration Airport Zones
designated under RMC 4-3-020.
9. "Public Suffix" (P) properties arc
allowed the following height bonus:
Publicly owned structures shall be
permitted an additional 15' in height
above that otherwise permitted in the
zone if "pitched roofs," as defined
herein, are used for at least 60% or more
of the roof surface of both primary and
accessory structures. In addition, the
height of a publicly owned structure
may be increased as follows, up to a
maximum height of 75' to the highest
point of the building:
a. When abutting a public street, I
additional foot of height for each
additional 1-112' of perimeter
building setback beyond the
minimum street setback required;
and/or
b. When abutting a common property
line, 1 additional foot of height for
each additional 2' of
perimeter building setback beyond
the minimum required along a
common property line.
10. In order to serve as a transition between
the lower density R4 zone and the
higher density .R -g zone "small lot
clusters" of up to a maximum of 50 lots
shall be allowed within 600 feet of an R-
S zone when at least 30% of the site is
permanently set aside as "significant
open space." Such open space shall be
situated to act as a visual buffer between
small lot clusters and other development
in the zone. The percentage of open
space required may be reduced by the
reviewing official to 20% of the site
when:
a) Public access is provided to open
space,
b) Soft surface trails are provided
within wetland buffers, and
c) Store water ponds are designed
to eliminate engineered slopes
requiring fencing and enhanced to
allow passive and/or active
recreation.
11. a) Lot size midth and depth may be
reduced by the reviewing official when,
due to lot configuration or access, 4 -
dwelling units per net acre cannot be
achieved. The reduction shall be the
minimum needed to allow 4 -dwelling
units per net acre and shall be limited to
the following minimum dimensions:
Lot size - 7,200 sq. ft
Lot depth — 70 feet
Lot width - 60 feet
12. When lot size is reduced for the purpose
of achieving maximum density, setbacks
may also be reduced. Setback reductions
shall be limited to the following:
Front — 20 feet.
Side yard along a street —15 feet
primary structure, 20 feet attached
garage with access from the side yard.
Minimum side yard combined setback —
15 feet.
Minimum for one yard — 5 feet.

the Mosier Il, Maplewood East and
Anthone, the following standards apply.
Vested plats must be developed within 5
years of preliminary plat approval and/or
annexation.
Maximum Density - 5 dwelling
units per net acre
Minimum Lot Size - 7,200 sq. R
Minimum Lot Width - 60 feet for
interior lots, 70 feet for corner lots
Minimum Lot Depth - 70 feet
Minimum Front Yard - 15 feet for the
primary structure, 20 feet for an
attached or detached garage. For a unit
with alley access garage, the front yard
setback for the primary structure may be .
reduced to 10 feet if all parking is
provided in the rear yard of the lot with
access from a public right of way or
alley.
