SUBJECT: Springbrook Apartments
17249 Benson Road South, Renton, WA
General: We have completed a preliminary review of the pre-application for the above-referenced
development proposal. The following comments on development and permitting issues are based on
the pre-application submittals made to the City of Renton by the applicant and the codes in effect on
the date of review. The applicant is cautioned that information contained in this summary may be
subject to modification and/or concurrence by official decision-makers (e.g., Hearing Examiner,
Community & Economic Development Administrator, Public Works Administrator, Planning Director,
Development Services Director, and City Council). Review comments may also need to be revised based
on site planning and other design changes required by City staff or made by the applicant. The applicant
is encouraged to review all applicable sections of the Renton Municipal Code. The Development
Regulations are available for purchase for $50.00 plus tax from the Finance Division on the first floor of
City Hall or online at www.rentonwa.gov.
Project Proposal: The subject property is located at 17249 Benson Road South at the northwesterly
corner of the intersection of Benson Drive South and Benson Road South. The site consists of two
parcels (APN 292305-9009 and 292305-9148) totaling 164,828 square feet (3.78 acres). The parcels have
a Residential High Density (RHD) land use designation and a Residential Multi-Family (RMF) zoning
classification. The project site is currently undeveloped with a ground cover of second growth conifer
and deciduous trees and brush.
The new 4-story, multi-family residential building on the north parcel will contain approximately 82
dwelling units. A 2-story building is proposed on the southern parcel near the intersection of SR 515 and
Benson Rd S containing 8 residential units. The proposal includes 122 surface parking stalls.
Primary vehicular access to the north apartments will be provided by a single curb cut along SE 172nd
Street to the onsite surface parking south of the residential building and crosses to the site, and a Class
NS stream, to serve the structure on the southern portion of the site. Secondary access is proposed via
two curb cuts along Benson Rd and a restricted right-turn in/out driveway, just south of the stream on
SR 515.
The applicant provided an alternative site plan which included the elimination of the structure on the
southern portion of the site. In its place the applicant has proposed and active and passive recreation
area. The alternative proposal would include a pedestrian crossing of the stream and the elimination of
a curb cut on Benson Rd S.
Current Use: Currently the site is vacant.
H:\CED\Planning\Current Planning\PREAPPS\14-000678
Development Standards: The project would be subject to RMC 4-2-110A, “Development Standards for
Residential Zoning Designations” effective at the time of complete application (noted as “RMF
standards” herein).
Zoning: Attached residential development is permitted within the RM-F zoning classification, provided
the proposal complies with the density range specified by the zone. The density range required in the
RM-F zone is a minimum of 10.0 to a maximum of 20.0 dwelling units per net acre (du/ac). There are
code provisions for a potential Density Bonus Review per RMC 4-9-065. However, the applicant should
note that the City is considering a docket item request in order to remove and/or amend the density
bonus allowances.
Up to a maximum of 5 additional dwelling units per net acre are allowed. To qualify for the density
bonus, the applicant shall first provide 1 affordable housing unit (per net acre), either for sale or rental.
Additional bonus units (per net acre) may be achieved on a 1:1 ratio for either:
(i) Affordable housing units, either for sale or rental, or
(ii) Units built to Built Green 3 Star (at minimum) building standards. Higher Built Green
standards are allowed and may receive a greater density bonus upon review and approval of the
Planning Director.
Combinations of the above are allowed; provided, that at least 1 unit of affordable housing (per
net acre) is provided. For example, 2 units of affordable housing and 2 units built to Built Green
3 Star standards would achieve a density bonus of 4 units.
Density bonus review shall occur concurrently with any other required land use permit that establishes
the permitted density and use of a site.
The area of public and private streets and critical areas would be deducted from the gross site area to
determine the “net” site area prior to calculating density. The pre-application packet did not indicate
the total square footage of the right-of-way that would be required to be dedicated; therefore the net
density could not be calculated. The gross density for the proposed 90 units is 23.8 du/ac. The
applicant would be required to demonstrate compliance with the density range of the RMF zone using
net density calculations.
A completed density worksheet is required with the formal land use submittal.
The property is also located within Urban Design District ‘B’, and therefore subject to additional
design elements. Proposals should have unique, identifiable design treatment in terms of landscaping,
building design, signage, and street furniture.
Minimum Lot Size, Width and Depth – There is no minimum lot size required for the RM-F zone. The
minimum lot width required is 50 feet and the minimum lot depth required is 65 feet. The applicant
would be requesting a lot consolidation as part of the Site Plan application. The proposed lot
consolidation would meet the development standards of the zone.
Building Standards – The RM-F zone restricts building height to 35 feet. An additional ten feet (10')
height for a residential dwelling structure may be obtained through the provision of additional amenities
such as pitched roofs, additional recreation facilities, underground parking, and additional landscaped
open space areas; as determined through the site development plan review process and depending on
the compatibility of the proposed buildings with adjacent or abutting existing residential development.
In no case shall the height of a residential structure exceed forty five feet (45').
Building lot coverage is limited to 35%. A maximum building coverage of 45% may be allowed through
the Hearing Examiner site development plan review process. Impervious surface coverage is limited to a
maximum of 75%. Lot coverage ratios were not provided with the pre-application packet; therefore
staff could not confirm compliance with the building standards for the RM-F zone. The applicant will be
required at the time of formal land use application to provide lot coverage and impervious surface
H:\CED\Planning\Current Planning\PREAPPS\14-000678
calculations. A maximum building coverage of 45% may be obtained through the Hearing Examiner
site development plan review process.
Setbacks – Setbacks are the minimum required distance between the building footprint and the
property line and any private access easement. The required setbacks in the RM -F zone are 20 feet in
the front, 15 feet in the rear, and 20 feet for side yards along-a-street, and 12 feet for the interior side
yard setback. The entire structure shall be set back an additional one foot (1') for each ten feet (10') of
height in excess of thirty five feet (35') to a maximum cumulative setback of twenty feet (20'). It appears
the proposal complies with the setbacks of the RMF zone.
Screening – Screening must be provided for all surface-mounted and roof top utility and mechanical
equipment. The site plan application will need to include elevations and details for screening.
Refuse and Recycling Areas – Refuse and recycling areas need to meet the requirements of RMC 4-4-
090, “Refuse and Recyclables Standards.” For multi-family development, a minimum of 1-½ square feet
per dwelling unit shall be provided for recyclable deposit areas, and a minimum of 3 square feet per
dwelling unit shall be provided for refuse deposit areas with a combined total minimum area of 80
square feet. The future site plan shall include locations for refuse and recycling collection points. There
shall be a minimum of one refuse and recyclable deposit area for each building and collection points
shall be located no more than two hundred feet (200') from a common entrance. The proposal would
be required to demonstrate compliance with the refuse and recycling standards of the code at the
time of Site Plan Review.
Landscaping – Except for critical areas, all portions of the development area not covered by structures,
required parking, access, circulation or service areas, must be landscaped with native, drought-resistant
vegetative cover. The development standards require that all pervious areas within the property
boundaries be landscaped. The minimum on-site landscape width required along street frontages is 10
feet, except where reduced through the site plan development review process. Parking is not permitted
within required landscape areas.
Please refer to landscape regulations (RMC 4-4-070) for additional general and specific landscape
requirements (enclosed). Please note all parking lots, with more than 100 stalls, are required to
provide 35 square feet of interior parking lot landscaping per parking space. A conceptual landscape
plan and landscape analysis meeting the requirements in RMC 4-8-120D.12 shall be submitted at the
time of application for Site Plan Review.
Tree Preservation - The site is forested and vacant, primarily vegetated with red alder, big leaf maple,
black cottonwood and Oregon ash with a salmonberry, sword fern, ocean spray and Himalayan
blackberry understory. The site contains a total of 440 trees of 6-inch caliper or larger; 40 are within the
proposed public right-of-way, and 94 are located in critical areas, with their buffers resulting in 306
protected trees on site. A tree inventory and a tree retention plan along with a tree retention
worksheet shall be provided with the formal land use application. The tree retention plan must show
preservation of at least 20 percent (20 %) of significant trees, and indicate how proposed building
footprints would be sited to accommodate preservation of significant trees that would be retained.
The Administrator may authorize the planting of replacement trees on the site if it can be demonstrated
to the Administrator's satisfaction that an insufficient number of trees can be retained. They may be
replaced with minimum 2 inch caliper trees at a rate of six to one.
Significant trees shall be retained in the following priority order:
Priority One: Landmark trees; significant trees that form a continuous canopy; significant trees
on slopes greater than 20%; significant trees adjacent to critical areas and their associated
buffers; and significant trees over 60’ in height or greater than 18” caliper.
Priority Two: Healthy tree groupings whose associated undergrowth can be preserved; other
significant native evergreen or deciduous trees; and other significant non-native trees.
Priority Three: Alders and cottonwoods shall be retained when all other trees have been
evaluated for retention and are not able to be retained, unless the alders and/ or cottonwoods
are used as part of an approved enhancement project within a critical area or its buffer.
H:\CED\Planning\Current Planning\PREAPPS\14-000678
A minimum tree density shall be maintained for multi-family development at a rate of 4 significant trees
for every 5,000 SF of land area. Tree density may consist of existing trees, replacement trees, trees
required pursuant to RMC 4-4-070F1, Street Frontage Landscaping Required, or a combination.
The Administrator may require an independent review of any land use application that involves tree
removal and land clearing at the City's discretion. A formal tree retention plan and arborist report
would be reviewed at the time of Site Plan Review application.
Fences – If the applicant intends to install any fences as part of this project, the location must be
designated on the landscape plan. A fence detail should also be included on the plan as well. Retaining
walls shall be composed of brick, rock, textured or patterned concrete, or other masonry product that
complements the proposed building and site development. Walls over 6-feet in height shall be terraced
pursuant to RMC 4-4-040. Additionally, there shall be a minimum three-foot (3') landscaped setback at
the base of retaining walls abutting public rights-of-way.
Parking – The following ratios would be applicable to the site:
Use Ratio
Attached Residential A minimum and maximum of 1.4 per 2 bedroom dwelling unit and 1.6
stalls per 3 bedroom unit
The applicant is proposing a total of 122 parking spaces. If the proposal provides more or less parking
than required by code, a request for a parking modification would need to be applied for and granted.
This detailed written request should be submitted by the applicant along with or prior to the land use
application process.
It should be noted that the parking regulations specify standard stall dimensions. Surface parking stalls
must be a minimum of 9 feet x 20 feet, compact dimensions of 8½ feet x 16 feet, and parallel stall
dimensions of 9 feet x 23 feet; compact surface parking spaces shall not account for more than 30
percent of the spaces in the surface parking lots.
ADA accessible stalls must be a minimum of 8 feet in width by 20 feet in length, with an adjacent access
aisle of 8 feet in width for van accessible spaces. The appropriate amount of ADA accessible stalls based
on the total number of spaces must be provided. Please refer to landscape regulations (RMC 4-4-070
and RMC 4-4-080F.7) for further general and specific landscape requirements (enclosed).
Additionally, the proposal would need to be revised in order to provide bicycle parking based on one -
half (0.5) bicycle parking space per one dwelling unit.
Bicycle parking shall be provided for secure extended use and shall protect the entire bicycle and its
components and accessories from theft and weather. Acceptable examples include bike lockers, bike
check-in systems, in-building parking, and limited access fenced areas with weather protection. Spaces
within the dwelling units or on balconies do not count toward the bicycle parking requirement.
However, designated bicycle parking spaces within individual garages can count toward the minimum
requirement.
Access –The applicant is proposing primary access to the site via 172nd St. The proposal also includes
two curb cuts on Benson Road South and an additional curb cut along Benson Drive S. The location of
ingress and egress driveways shall be subject to approval of the Department of Community and
Economic Development.
Pedestrian Access – Current pedestrian access is provided with existing concrete sidewalks along SR 515
and partial sidewalks on Benson Rd S. Half street frontage improvements along SE 172nd St. An existing
pedestrian connection from 172nd St to Benson Drive is proposed to be retained as part of the proposal.
Building Design Standards – Compliance with Urban Design Regulations, District ‘B’, is required. See
the attached checklist and Renton Municipal Code section 4-3-100. The following bullets are a few of
the standards outlined in the regulations.
H:\CED\Planning\Current Planning\PREAPPS\14-000678
Buildings shall be oriented to the street with clear connections to the sidewalk.
A primary entrance of each building shall be located on the facade facing a street, shall be
prominent, visible from the street, connected by a walkway to the public sidewalk, and include
human-scale elements.
The number of driveways and curb cuts shall be minimized, so that pedestrian circulation along
the sidewalk is minimally impeded.
All building facades shall include modulation or articulation at intervals of no more than twenty
feet (20').
Modulations shall be a minimum of two feet (2') deep, four feet (4') in height, and eight feet (8')
in width.
Architectural elements that incorporate plants, particularly at building entrances, in publicly
accessible spaces and at facades along streets, shall be provided.
All attached housing developments shall provide at least one hundred fifty (150) square feet of
private usable space per unit.
Any facade visible to the public shall be comprised of at least fifty percent (50%) transparent
windows and/or doors for at least the portion of the ground floor facade that is between four
feet (4') and eight feet (8') above ground (as measured on the true elevation).
Buildings shall use at least one of the following elements to create varied and interesting roof
profiles (see illustration, subsection RMC 4-3-100.I5f):
(a) Extended parapets;
(b) Feature elements projecting above parapets;
(c) Projected cornices;
(d) Pitched or sloped roofs.
Buildings shall employ material variations such as colors, brick or metal banding, patterns, or
textural changes.
Critical Areas – The subject site contains regulated slopes, unclassified coalmine hazards and an
unnamed Class 4 stream as identified in the “Wetland and Stream Delineations Study,” prepared by The
Watershed Company (dated January 25, 2008), and a “Supplemental Stream Study and Mitigation
Report,” prepared by The Watershed Company (dated February 11, 2009).
While the critical area information submitted with the pre-application materials indicates there will be
buffer reductions/averaging/and/or enhancement in order to accommodate the proposed building pad
it is unclear to the extent impacts are proposed. The applicant would be required to comply with RMC 4-
3-050. Please note City has passed a recent Critical Areas Ordinance. The following table represents the
current and proposed Critical Area Ordinance for buffers, setbacks, and allowed reductions:
Former New Former Former New Former New Former New
Class 4 Type Ns 35 feet 0 feet 15 feet 25 feet 40feet 25 feet 25 feet
Min Buffer
New
50 feet
Classification Standard Buffer Structure Setback Min Buffer
Proposed impacts are identified to the stream (i.e. the bridge/culvert crossing) as a result a
supplemental stream study would be required to be submitted with the formal land use application.
Construction of vehicular or non-vehicular transportation crossings may be permitted in accordance
with an approved stream/lake study subject to the following criteria:
i. The proposed route is determined to have the least impact on the environment, while meeting
City Comprehensive Plan Transportation Element requirements and standards in RMC 4-6-060;
and
ii. The crossing minimizes interruption of downstream movement of wood and gravel; and
iii. Transportation facilities in buffer areas shall not run parallel to the water body; and
iv. Crossings occur as near to perpendicular with the water body as possible; and
H:\CED\Planning\Current Planning\PREAPPS\14-000678
v. Crossings are designed according to the Washington Department of Fish and Wildlife Fish
Water Crossing Design Guidelines, 2013, and the National Marine Fisheries Service Guidelines for
Salmonid Passage at Stream Crossings, 2000, as may be updated, or equivalent manuals as
determined by the Administrator; and
vi. Seasonal work windows are determined and made a condition of approval; and
vii. Mitigation criteria of subsection L of this Section are met.
The applicant has submitted and alternative site plan which eliminates the need for a vehicular
crossing. Staff would be supportive of the alternative site plan which minimizes impacts to critical
areas on site and provides additional passive and active recreation opportunities.
Additionally a Geotechnical Engineering Report with a coalmine hazard assessment, prepared by Icicle
Creek Engineers, Inc. (dated January 26, 2009) was provided to the City with a former application. The
report describes the slopes as less than 25% grade and identifies a mine ventilation shaft located in the
southwest portion of the site adjacent to Benson Drive (SR 515). A structural plug was recommended for
the shaft entrance to mitigate any potential hazard. Geotechnical studies are typically valid for a period
of up to ten years; otherwise a geotechnical report will need to be submitted with the land use
application.
Environmental (SEPA) Review: SEPA is required due to the size of the project. Therefore, an
environmental checklist is a submittal requirement. An environmental determination will be made by
the Renton Environmental Review Committee. This determination is subject to appeal by either the
project proponent, by a citizen of the community, or another entity having standing for an appeal.
Permit Requirements: The proposal would require Hearing Examiner Site Plan Review, Environmental
Review, and potential street and parking modifications.
The purpose of the Site Plan process is the detailed arrangement of project elements so as to be
compatible with the physical characteristics of a site and with the surrounding area. An additional
purpose of Site Plan is to ensure quality development consistent with City goals and policies General
review criteria includes the following:
a. Compliance and Consistency. Conformance with plans, policies, regulations and approvals,
including:
b. Off-Site Impacts. Mitigation of impacts to surrounding properties and uses.
c. On-Site Impacts. Mitigation of impacts to the site
d. Access and Circulation. Safe and efficient access and circulation for all users.
e. Open Space. Incorporation of public and private open spaces to serve as distinctive project
focal points and to provide adequate areas for passive and active recreation by the
occupants/users of the site;
f. Views and Public Access. Provision of view corridors to shorelines and Mt. Rainier,
incorporates public access to shorelines, and arranges project elements to protect existing
natural systems where applicable.
g. Services and Infrastructure. Availability of public services and facilities to accommodate the
proposed use;
h. Signage. Use of signs primarily for the purpose of identification and management of sign
elements – such as the number, size, brightness, lighting intensity, and location – to
complement the visual character of the surrounding area, avoid visual clutter and distraction,
and appear in proportion to the building and site to which they pertain; and
i. Phasing. Inclusion of a detailed sequencing plan with development phases and estimated time
frames, if applicable.
H:\CED\Planning\Current Planning\PREAPPS\14-000678
The applicant will also be subject to Design Review as part of the Site Plan Review and a Design Checklist
shall be completed and submitted as part of the application materials (see attached).
