Renton Municipal Code 4-9-030 Conditional Use Permits
D. Decision Criteria: The following provides detailed information as justification for the approval of
the Conditional Use Permit (CUP).
1. Consistency with Plans and Regulations: The proposed use shall be compatible with the general
goals, objectives, policies and standards of the Comprehensive Plan, the zoning regulations and any
other plans, programs, maps or ordinances of the City of Renton.
The proposed school use is consistent and compatible with the comprehensive plan. The policies
listed below outline consistency with some of the most pertinent policies in the plan. There are
additional details and policies referenced within the SEPA Environmental Checklist.
Land Use Element
Policy L-31: Protect buffers along wetlands and surface waters to facilitate infiltration and maintain
stable water temperatures, provide for biological diversity, reduce amount and velocity of run-off,
and provide for wildlife habitat.
Policy L-34: Ensure buildings, roads, and other built features are located on less sensitive portions of
a site when sensitive areas are present.
Housing and Human Services Element
Policy HHS-17: Build on collaborative relationships; partner with local agencies and school districts
to increase affordability and availability of early childhood education, after-school youth
engagement opportunities, and preparation for college/career.
Policy HHS-23: Support the link between land development and physical activity by increasing
options for transit use, walking, and bicycling, such as providing physical connections between
residential areas and schools and/or commercial development.
Utilities Element
Policy U-29: Control runoff from new development, redevelopment, and construction sites through
the implementation of development design standards and construction techniques that promote the
use of best management practices to maintain and improve storm water quality and manage
stormwater flow.
Capital Facilities Element
Policy CF-5: Individually adopt by reference the most current Capital Facilities Plans for the Kent
School District #415, the Issaquah School District #411, and the Renton School District #403, and

adopt an implementing ordinance establishing a school impact fees consistent with each District’s
adopted Capital Facilities Plan, if the Plan demonstrates that the facilities are needed to
accommodate projected growth.
School uses are allowed through the Conditional Use process and requirements for that approval
have been included. The project design meets the requirements of the zoning code for setbacks,
height, landscaping, drainage, wetland and transportation. The school use is also consistent with,
and discussed in, the District’s Capital Facilities Plan that is adopted by the City.
2. Appropriate Location: The proposed location shall not result in the detrimental overconcentration
of a particular use within the City or within the immediate area of the proposed use. The proposed
location shall be suited for the proposed use.
There is a need for an elementary school within this vicinity of the school district boundary. The
proposed Elementary School #16 is part of the 2019 School Construction Bond, which raised
nearly $250 million. Population growth in the Renton Highlands area has led the District to need
additional classroom capacity for elementary school students. The site is well served by utilities
and a transportation network that can meet the needs of a school site. While Hazen High School
is located across Duvall Ave NE, the development of the site for an elementary school provides
that resource to the surrounding residential community.
3. Effect on Adjacent Properties: The proposed use at the proposed location shall not result in
substantial or undue adverse effects on adjacent property.
Consideration of adjacent uses was implemented in the design layout and visual considerations.
The placement of the school building internally and adjacent to parking and bus drop -off has
reduced impacts of the uses and structure to the adjacent community. The preservation of Wetland
C would continue to provide an environmental asset to the community and buffer from adjacent
residential uses. Numerous existing trees would be preserved, and landscaping and perimeter
setbacks would meet code requirements. There would be increased traffic on Chelan Ave NE, but
this would be mainly limited to AM arrivals and PM end of school. Noise levels generated by the
school use are within code limits.
4. Compatibility: The proposed use shall be compatible with the scale and character of the
neighborhood.
In order to reduce the overall ‘bulk’ of the building, the façade has been carefully subdivided to
assist the transition to the surrounding residential uses. The classroom wings are broken into
sections, providing articulation of the façade every 1-2 classrooms. These sections are further
subdivided by use of materials and color to again subdivide the mass into smaller sections. Along
Duvall Ave NE the building uses roof lines and materials to reduce the scale of the building.
The main visitor and staff parking lot is located to the south of the proposed school, and is screened
from surrounding streets by landscaping and buildings. Driveways and curb cuts have been
minimized.

The proposed design incorporates prominent architectural features and varying rooflines to divide
the building façade into smaller increments. Variations in materials and material application have
been utilized to create a visually attractive, durable design. The project would incorporate site
lighting at a level necessary to ensure the safety and security of all visitors while not impacted
adjacent residential uses. The District has been in contact with the Renton Jehovah’s Witnesses
Church and the school development would not impact the church use or operation.
5. Parking: Adequate parking is, or will be made, available.
The proposal includes on-site parking for a total of 82 automobiles (79 in the main staff/visitor lot
and 3 in the bus load/unload area). The school-bus load/unload area has room for 8 full-size
(typically 40 feet long) school buses and two special education (SPED) buses (typically 25 feet
long); although current planning indicates the school would be served by eight or fewer buses.
During evening and/or weekend events, the school-bus load area could be used for automobile
parking, which is estimated to accommodate about 20 vehicles.
City of Renton Municipal Code section 4-4-080.F.10.d outlines the parking requirements for a
variety of land uses. For elementary schools, the City requires a minimum and maximum of 1
parking space per employee. The proposed school is expected to have 60 employees when
enrolled at its planned capacity of 650 students. Based on these values, the City would require a
minimum and maximum of 60 parking spaces. The proposed parking supply would exceed City
code requirements. As a result, the District is requesting a modification to exceed the number of
parking spaces on-site.
6. Traffic: The use shall ensure safe movement for vehicles and pedestrians and shall mitigate potential
effects on the surrounding area.
The school site design has provided for the safe movement of vehicles to the site and for queuing
on-site. Vehicular safety during construction was also considered during the planning. Parking
layouts are designed to allow for parent queuing during drop off an d pick up. Bus parking has
been provided along the bus drop off located off of Duvall Ave NE. The District would require
the selected contractor to develop a construction management plan (CMP) that addresses traffic
and pedestrian control during school construction. It should define truck routes, lane closures,
walkway closures, and on-street parking disruptions, as necessary. To the extent possible, the
CMP should direct trucks to arterials and away from residential streets to avoid unnecessary
conflicts with resident and pedestrian activity. The CMP should identify parking locations for the
construction staff; to the extent possible, construction employee parking should be contained on -
site.
Other transportation mitigation includes:
The City collects transportation impact fees and has outlined fee rates for a variety of uses. The
transportation impact fee for the elementary school project is calculated to be $356,377.
The project would dedicate right-of-way along the street frontages of Duvall Ave NE and Chelan
Ave NE. The dedication along Duvall Ave NE would be about 887 linear feet along the length of
CUP Attachment (Justification) – Elementary School #16 Page 4
BRENT PLANNING SOLUTIONS, LLC FOR RENTON SCHOOL DIST. NO. 403 (3-2021)
the property line and could vary between 7.5 and 12 feet in width. The total area of the dedication
could range from about 8,220 SF (if the dedication varies between 7.5 and 12 feet) and about
10,646 SF (if a straight-line dedication is required). The six-inch dedication along Chelan Ave
NE would be about 272 linear feet long with a total area of about 136 SF.
Frontage improvements would be made along Duvall Ave NE and Chelan Ave NE. The District
would coordinate with the City to integrate the dedication areas and frontage improvements with
the City’s planned roadway improvement in that segment.
To mitigate school-related traffic impacts, the project would install a traffic signal (replacing the
existing HAWK beacon signal) at the NE 10th Street / Duvall Ave NE intersection. Installation of
the new traffic signal would include pedestrian actuated signals and crosswalks on all four legs.
In addition to these measures the District would communicate with staff, students and the
community information on proper access to the school and parking for school and event days.
7. Noise, Light and Glare: Potential noise, light and glare impacts from the proposed use shall be
evaluated and mitigated.
A noise study was conducted for the project. Model-calculated sound levels of on-site traffic and
chiller (equipment) operations during peak morning arrival indicate compliance with the
applicable noise limits during daytime hours. Model-calculated sound levels of chiller operations
simultaneously with generator maintenance indicates this activity would comply with the daytime
noise limits at all receptor locations. Consideration of potential increases in noise due to morning
arrival traffic and chiller operation results in estimated increases of 0 to 2 dBA at all residences
near the site. Such increases in an active, outdoor environment would be difficult to discern, and
the project is not expected to result in substantial noise impacts.
A lighting plan is included with the CUP submittal. All exterior building lighting would be
directed downward and shielded to minimize glare on the nearest properties. Every fixture on the
exterior would be provided with a motion sensor.
8. Landscaping: Landscaping shall be provided in all areas not occupied by buildings, paving, or
critical areas. Additional landscaping may be required to buffer adjacent properties from potentially
adverse effects of the proposed use.
The Landscape Plan for the site was designed to utilize native and drought tolerant plant materials
to reduce the need for long-term use of supplemental irrigation. The landscape design avoids the
use of any plants that require intensive hand pruning or weed ing. Portions of the development
area not covered by structures or other paved areas, would be landscaped with native, drought -
resistant vegetative cover. Irrigation would be provided to enhance plant establishment. The City
requires the following landscaping be provided, which has been incorporated into the site design:
1. A landscape strip 10 feet in width along all public street frontages (private side) and would
include trees, shrubs, and groundcover.
2. Planting in the right-of-way planter strip between the curb and sidewalk with trees and
groundcover has been shown on the plans.

3. Nonresidential development in a residential zone requires a 15-foot wide partially sight-
obscuring landscaped visual barrier or a 10-foot wide fully sight-obscuring landscaped visual
barrier along common property lines, which is included.
4. Interior parking lot landscaping areas would be sized to dimensions of at least eight feet (8')
by twelve feet (12').
5. A 15-foot perimeter landscaping screen (located outside of any required fencing) is required
around storm drainage facilities and has been shown on the plans.
In addition to the landscaped areas, there would be seeded turf, synthetic turf and wood chip
surfaces.
