APPLICANT: Matt Weber, AHBL, 2215 N 30th St Suite 300, Tacoma, WA 98407
PROJECT NAME: Walker Auto Dealership
PROJECT DESCRIPTION: The applicant is requesting Site Plan and Environmental (SEPA) Review to
construct a 64,935 square foot auto dealership on a site previously occupied by auto junk yard. The subject property is
located at 3400 East Valley Road (APN 3023059067) near the intersection of East Valley Road and SW 34th St. The project
site totals 5.65 acres in area and is zoned Commercial Arterial (CA). The site is located in the Automall Area C Overlay
District. Two existing buildings are presently located on the site and are proposed for demolition as part of the project.
The previous use located on the property resulted in a significant amount of contamination due to the decomposition of
the junk vehicles. The applicant has proposed to remediate the site under Department of Ecology’s Voluntary Clean-up
program authorized by the Washington Model Toxics Control Act. The proposed new structure would include a
showroom/sales area, parts sale and storage area, service and shop, and various other support areas. Access to the site
is proposed via three new driveways off of East Valley Road. The site is mapped with a high seismic hazard. According to
the applicant, a Category III wetlands is located within the SR 167 ROW directly east of the site. The applicant submitted
a Geotechnical Report, a Drainage Report, a Wetland Report, and a Traffic Study with the application.

CONSTRUCTION PHASE
Theft from construction sites is one of the most commonly reported crimes in the City. To protect materials
and equipment it is recommended that all materials and tools be locked up when not in use. The site should
have security lighting, and any construction trailer or storage area should be completely fenced-in with portable
chain-link fencing. The fence will provide both a physical and psychological barrier to any prospective criminal
and will demonstrate that the area is private property. Construction trailers should be kept locked when not in
use, and should be fitted with heavy-duty deadbolts with a minimum 1-1/2” throw when bolted. Any
construction material that contains cop per should be removed from the construction site at the end of each

working day. Glass windows in construction trailers should be shatter-resistant. Toolboxes and storage
containers should be secured with heavy-duty padlocks and kept locked when not in use.
“No Trespassing” signs should be posted on the property during the construction phase. These signs will allow
officers, upon contact, to provide a verbal warning to trespassers that should they be contacted on the property
again, they could be cited and/or arrested.
COMPLETED FACILITY
All exterior doors should be made of solid metal or metal over wood, with heavy -duty deadbolt locks, latch
guards or pry-resistant cylinders around the locks, and peepholes. All strikeplates should have 2-1/2 to 3” wood
screws. If glass doors are used, they should be fitted with the hardware described above and additionally be
fitted with a layer of security film. Security film can increase the strength of the glass by up to 300%, greatly
reducing the likelihood of breaking glass to gain entry. Access to the back of the buildings should be limited,
preferably with security fencing or gates, as these areas could be vulnerable to crime due to the lack of natural
surveillance by vehicle and/or pedestrian traffic.
It is important to direct all foot traffic into the main entrance of the building. Any alternative employee
entrances should have coded access to prevent trespassing.
All areas of this project need to have adequate lighting. This will assist in the deterrent of theft of and from
motor vehicle as well as provide safe pedestrian travel for customers utilizing the business.
The structure should have a building number clearly posted with numbers at least 6” in height and of a color
contrasting with the building. This will assist emergency personnel in locating the correct location for response.
Landscaping should be installed with the objective of allowing visibility – not too dense and not too high. Too
much landscaping will make customers and employees feel isolated and will provide criminals with conceal ment
to commit crimes such as burglary and malicious mischief (property destruction).
It is important for safety and security reasons to have appropriate lighting and signage. Use plenty of lights
throughout your property, not just in the areas you thin k are most vulnerable. “No Trespassing” signs should
be posted in conspicuous locations throughout the property, including entrances to the property and parking
areas.
Garbage and recycling dumpsters, according to plans, are placed in the farthest corne rs behind the property,
bordering greenbelt area. Due to limited visibility of this area it is recommended dumpster areas be gated and
locked during and after business hours to prevent loitering, illegal dumping and/or tampering. Additional
lighting should also be placed around these areas for extra visibility.
Most theft of vehicles from dealerships is the result of keys and key fob’s not properly secured. To prevent theft
of automobiles and inventory at car dealerships, it is recommended to put in pla ce a high level of security around
key management. Electronic key cabinets are one recommendation that come with audit tracking systems to
secure keys and allow inventory control as well as require specific check-in/check-out monitoring. Key
management is to include the service department when customer vehicles left on-site for overnight service have
keys readily available to “grab & go”.

It is recommended that the dealership lot have proper barriers and fencing in place to prevent theft. Fencing
with barbed wire is recommended to store surplus inventory. Gates are recommended at all entrances/exits
and secured after hours to make it more difficult to drive vehicles off the lot due to theft. Bollards are
recommended throughout the property to prevent theft of vehicle. In review of the plans it looks like there will
be some bollards placed around the main building. When considering bollards as a deterrent to vehicle theft,
note that bollards can be placed throughout several areas of the property as permanent, decorative, and/or
moveable.
Due to the high-dollar inventory at auto dealerships, hired security guards and video monitored surveillance is
recommended. Guards can patrol major access points and minimized the threat of loss. The presence of guards
patrolling a property can discourage criminals from targeting your dealership. An auxiliary security service could
be used to patrol the property, preferably between the hours of 10:00 p.m. and 6:00 a.m. Video monitored
surveillance for this type of inventory should be in “real time”. If an alarm is tripped and is being monitored,
police can be dispatched immediately, increasing the chance of preventing the theft before it happens and
possibly arrest of a suspect. If you choose to use security guards and/or surveillance, post signs throughout the
property announcing that you do so. Let would-be criminals know you are watching.
I highly recommend that the developer have a Renton Police Crime Prevention Representative conduct a
security survey of the premises once construction is complete.

SUBJECT: Utility and Transportation Comments for Walker Subaru
3400 East Valley Road
LUA 18-000305
I have reviewed the application for the Walker Subaru at 3400 East Valley Road (APN(‘s) 3023059067) and have the
following comments:
EXISTING CONDITIONS
The site is approximately 5.65 acres in size and is square in shape. The existing site is mostly impervious gravel area which
has been used as a vehicle storage lot. Site soils are generally contaminated with oils from the continued use of vehicular
storage.
Water Water service is provided by City of Renton. The site is in the Valley service area in the 196 hydraulic pressure
zone. There is an existing 12-inch City water main located in East Valley Road (see Water plan no. W-0304) that
can deliver a maximum total flow capacity of 5,000 gallons per minute (gpm). The approximate static water
pressure is 75 psi at the elevation of 20 feet. The site is located outside of an Aquifer Protection Area. There is
an existing 3/4-inch water meter serving the existing building on the property.
Sewer Wastewater service is provided by the City of Renton. There is an existing 8-inch PVC wastewater main located
in East Valley Road (see City plan no. S-0200).
Storm There is an existing storm drainage system in East Valley Road (see City plan no. R-1999). There no existing on-
site conveyance system or stormwater features. Surface run-off from the site appears to drain to the abutting
wetlands as well as to the public drainage system in East Valley Road.
Streets East Valley Road is a Collector Arterial Street with an existing right of way (ROW) width of 85 as measured using
the King County Assessor’s Map. Current street frontage improvements include curb and gutter and a 6-ft
sidewalk on both sides of the street. The site borders State Route 167 (SR 167) on the east property line.
WSDOT has identified, in their long-range planning programs for I-405 and SR-167, a direct access connection
to and from the south at SW 27th Street, which the City supports. Applicant should further coordinate with
WSDOT at 425-456-8538 for further coordination and to verify any future impacts related to widening of the
highway.

SURFACE WATER
1. A geotechnical report, dated April 27, 2018, completed by Migizi Group, Inc., for the site has been provided.
Erosion control measures will need to be in place prior to starting grading activities on the site. The report
discounts the use of infiltration due to the high groundwater table present on the project site. Geotechnical
recommendations presented need to be addressed within the project plans.
2. A Preliminary Drainage Plan and Technical Information Report (TIR), dated May 2018, was submitted by AHBL with
the Land Use Application. Based on the City of Renton’s flow control map, the site falls within the
Peak Rate Flow Control Standard area matching Existing Site Conditions and is within the Black River Drainage
Basin. The development is subject to Full Drainage Review in accordance with the 2017 Renton Surface Water
Design Manual (RSWDM). All nine core requirements and the six special requirements have been discussed in the
Technical Information Report.
3. As discussed in the TIR, the applicant has determined that the redevelopment project is exempt from Core
Requirement #3, Flow Control, since the proposed development will result in less than a 0.15 cfs increase in
surface water run-off from the existing site conditions 100-year peak flow rate when modeled using the latest
version of the Western Washington Hydrology Model (WWHM 2012), as outlined in Core Requirement #3.
a. The redevelopment project is proposing to upgrade existing gravel and/or hard compacted dirt to
asphalt. The existing ground surface is not currently serviced by an existing piped or channeled
conveyance system. As such, while the existing ground surface is defined as an existing impervious area,
it is classified as an existing non-effective impervious area for the purposes of continuous modeling land
cover types per Section 3.2.2.
b. As defined in Section 3.2.2, non-effective impervious area is assumed to have the same hydrologic
response as the immediately surrounding pervious area. Therefore, the existing gravel/hard compacted
dirt land cover shall be modeled as grass rather than impervious surface.
c. The applicant will need to provide an updated WWHM model demonstrating compliance with the
exception criteria outlined in Section 1.2.3.1.A as part of the civil construction permit application. If the
