RE: Brotherton Cadillac Dealership Project, Renton, Washington
PRE20-000304
Site Plan Review/SEPA/Conditional Use Permit
Dear Sir or Madam,
This project includes the design and construction of a 16,600 SF stand-alone Cadillac retail
automobile sales & service facility, to be located due East of the existing Brotherton
GMC/Buick/Cadillac facility at 215 SW 12th Street, Renton, WA., as well as a 4,416 SF addition
to their existing service department functions, at the existing GMC/Buick building.
We have been directed by City Staff to prepare separate Building permit submittal packages for
the two projects; but for the purposes of SEPA and Site Plan Review processes, we have
combined these for simplicity, since both are common “ownership”, for the same client.
Cadillac Building:
The building footprint for the Cadillac building will be approximately 16,600 square feet, which
includes approximately 5,200 SF for the Service Bay portion, and with spaces for the
showroom, sales, customer lounge, conference room, sales manager, F & I office, and toilet
rooms. There will be a covered drive-thru module for service write-up. Exterior walls will be ACM
panels, with a vertical parapet to conceal rooftop mechanical equipment. The showroom area
will receive extensive storefront glass on two sides. The front and left side facades will feature
the Cadillac brand exterior treatment of ACM panels, with opposing geometric planes, per their
current National branding concept.
The main structure will most likely be of conventional building components using metal or wood
stud walls, exterior plywood sheathing, and ACM panels over a moisture barrier. The roof
system will also be conventional, with a low-slope single-ply membrane roof. The mezzanine
above will be unoccupied space, for storage use only, and will be framed with conventional steel
or wood joists, decking, and a topping slab of light weight concrete for sound attenuation. There
will be one stairway. The storage mezzanine will not exceed approximately 2,900 SF in area.
Exterior walls of the Service module will be CMU masonry; with integral color and a mix of
textures and/or patterns.
Also proposed on this site is a 1,200 SF metal carport structure, for six customer and EV vehicle
parking stalls.

Site improvements will include asphalt paving, underground utilities for water, sanitary sewer,
and storm drainage, landscaping & irrigation, a Pylon sign within the exterior “plaza” along SW
12th Street, and a bicycle rack.
To the best of our knowledge the current building & site design does conform with the following
criteria:
1. Consistency with Plans & Regulations:
Chapter 4 of the City of Renton Development standards, specifically:
4-3-100 (E), Site Design & Building location: orientation to the street; building entry with
overhang at the main entry; building articulation, trash enclosure with appropriate screening,
parking location and orientation with landscaping where required, and pedestrian amenities
along SW 12th Street.
Building Character and Massing: Modulation/Articulation: We note that the exterior façade of the
main building, especially the showroom and Service Drive modules will comply with these
requirements by virtue of the ACM “Boneline” of the Cadillac branding, with its multiple angular
facets, coupled with the differing roof & parapet heights. Reference the photo image of the
building exterior provided by Cadillac on our facing page. Sheet5 G1.1.
Ground Level Details: There is no tinted or mirror glazed windows; no untreated blank walls
facing the street. Glazing on the exterior of the showroom façade easily exceeds a 50% ratio;
Building Roof Lines: exterior parapet heights are varied; roof-mounted mechanical devices will
not be visible to pedestrians.
Building Materials: The exterior of the Showroom & Service Drive modules (the portions of the
building that are generally visible from SW 12th Street) will feature a combination of materials,
such as ACM metal prefinished panels, and storefront glazing; the Service Department module
to the rear of the building will feature painted CMU masonry, with variations in texture, and
coursing.
Lighting: Although we are not submitting detailed lighting plans at this time, we acknowledge
and will comply with the requirements for pedestrian scale exterior lighting at building entrances,
accent lighting in several locations, and all will be “downlight” type fixtures.
4-4-070 Landscaping:
Our conceptual landscaping plan addresses adequate perimeter landscaping of the site,
coupled with generous landscaping along the street frontage. Landscaping is placed adjacent to
customer parking stalls; but is not required at vehicle inventory or display stalls. Since the
required number of parking stalls does not exceed 15 stalls, the total area of interior
landscaping will comply at the ratio of 15 SF/stall, per the Table in 4-4-070, F, 6.
2. Appropriate Location: The proposed location for these two projects is consistent and fully
compatible with the adjacent automotive sales & services facilities in the surrounding area, all
within the Commercial Arterial Automall Zoning District.
Page 3 of 4 Castino Architecture 8911 71st Ave NW, Gig Harbor, WA 98332 www.castino-arc.com
3. Effect on Adjacent Properties: The two projects will not result in substantial or undue adverse
effects on adjacent properties, given the same or similar uses within the Commercial Arterial
Automall District.
4. Compatibility: These two projects are completely compatible with the scale and character of
the surrounding uses, within the Commercial Arterial Automall Zoning District.
5. Parking: Our proposed site plan has addressed the various requirements in Section 4-4-080,
for customer parking stall dimensions and required quantities, both minimum and maximum per
the table in section E, 10, (D), based upon the occupancy designations for this project.
Reference the calculations on the site plans.
6. Traffic: Per response given above to #5, adequate customer parking will be provided in
accordance with the maximum quantities allowed in the Development Code.
7. Noise, Light & Glare: All exterior light fixtures will comply with requirements for downlighting;
all vehicle maintenance & repair functions of the facility will be contained within the confines of
the Service Department module, thus minimizing exterior noise.
8. Landscaping: Our conceptual landscaping plan addresses adequate perimeter landscaping of
the site, coupled with generous landscaping along the street frontage. Landscaping is placed
adjacent to customer parking stalls; but is not required at vehicle inventory or display stalls.
Since the required number of parking stalls does not exceed 15 stalls, the total area of interior
landscaping will comply at the ratio of 15 SF/stall, per the Table in 4-4-070, F, 6.
Service Addition to the Existing Buick/GMC Building:
The proposed addition to the existing service department in the GMC/Buick building will be
approximately 4,900 square feet, attaching to the West wall of that building, directly adjacent to
the new car delivery space that was constructed in 2011. There will be provisions for six
additional service bays with hydraulic lifts, tool boxes, equipment, and drive-through capability
on two sides. We will design a pedestrian pathway allowing mechanics the ability to
communicate between the two service areas, for commonality to Parts and other functions; this
will require a structural modification in that existing East wall.
This structure will blend with the existing building, with CMU masonry exterior walls and
parapet; with a roof system using metal bar joists and decking and a single-ply membrane low-
slope roof.
Site improvements for this structure will generally be limited to removal of existing asphalt, re-
grading as necessary for foundation & footings, asphalt patching, and minor modifications to the
existing parking curbs. The existing pylon sign in that area will remain.

· Colored Rendering.
· Land Use Master Application.
· Architectural plans, including site plans, floor plans, building elevations.
· Civil plans, including site surveys, conceptual site plans, grading plan, storm drainage,
underground utilities, landscaping, and preliminary drainage report.

Request for Exemption, 4-6-090 Overhead Utility Lines
As a part of this submittal, our client is requesting an exemption for relocating the existing
overhead power lines along the street frontage of SW 12th Street, under Section D, ii:
“ii: The cost of undergrounding such a facility outweighs the general welfare
consideration…”
We note that the owner has been advised that the cost of relocating these power poles
underground could cost upwards of $500,000.00, and additionally these facilities are the
property of Puget Sound Energy.
Please know that under our proposed design, the primary power line to the Cadillac building will
be installed underground, from the transformer to the building.
Respectfully submitted,
