PROJECT DESCRIPTION: The applicant is requesting Hearing Examiner Site Plan Review, Environmental (SEPA)
Review, and three (3) modifications for a proposed expansion to the Chateau at Valley Center Assisted Living Facility located
on the campus of the Valley Medical Center. The proposed project, Chateau Valley Tower, would be located on the 0.58-acre
parcel at 4320 Davis Ave S (APN 6391800125), which is north of the existing 2.2-acre Phase I Chateau at Valley Center Assisted
Living Facility at 4450 Davis Ave S (APN 6391800010). Phase I was completed in 2005 with 126 apartment units. As part of
Phase II, the applicant is proposing two (2) levels of structured parking under the building with 66 parking stall and 73
residential units. The proposed new assisted living building would have a density of 126 dwelling units per net acre and the
tower would extend eight-stories above finished grade with a roof height of nearly 84 feet above the entry level of the
building. The units would be a mix of one (1) bedroom, one (1) bedroom plus den and two (2) bedroom. The top floor would
also include a dining room, a lounge/activity room and an outside garden with vegetated walking paths. The new facility
would connect to the existing facility on levels one through four. The subject property is located in the Commercial Office (CO)
zoning classification and Commercial & Mixed Use (CMU) land use designation. Access to the site would be provided via two
(2) existing curb cuts and one (1) proposed new curb cut on Davis Ave S. The applicant is requesting a street modification to
Davis Ave S to retain the existing right-of-way width of 50 feet, retain the existing roadway section, and add one new curb cut
approximately 34 feet from the existing curb cut to access the upper parking level. The applicant is also requesting a bicycle
parking modification to reduce the number of required bicycle parking spaces and a refuse and recycling modification to
reduce the size of the trash enclosure area. According to the City's Critical Area Map (COR Maps), the southeast portion of the
site contains regulated slopes. The proposed addition would remove three (3) existing trees onsite and would provide 21 new
replacement trees. The applicant has submitted Geotechnical Engineering Study, Geotechnical Supplement, Preliminary

characteristics of the site including infiltration potential and provide recommendations
for project design and construction. The geotechnical report discounts the use of
infiltration for the site based on the high ground water present. Geotechnical
recommendations presented need to be address within the project plans. The following
adjustments shall be made to the geotechnical report prior to Civil Construction Permit
Application Submittal in order to address Best Management Practices (BMPs) listed as
part of Renton Surface Water Design Manual (RSWDM):
a. The geotechnical engineer shall evaluate the seasonal groundwater table as it
relates to the location and depth of potential BMPs such as permeable
pavement and similar BMPs. Specific groundwater infeasibility noted in
RSWDM.

b. If the depth of groundwater is suitable for proposed BMPs, infiltration testing
shall be performed within the proposed parking lot to determine if permeable
pavement or similar BMPs are feasible.
2. Development Management Engineers, LLC with the Land Use Application, submitted a
Preliminary Drainage Plan and Technical Information Report (TIR), dated July 11, 2019
(revised August 28, 2019). Based on the City of Renton’s flow control map, the site falls
within the Flow Control Duration Standard Area matching Forested 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.
a. Flow Control, RSWDM Core Requirement #3: Any proposed detention and/or
water quality vault shall be designed in accordance with the RSWDM that is
current at the time of civil construction permit application. Separate structural
plans will be required to be submitted for review and approval under a separate
building permit for the detention and/or water quality vault. Special inspection
from the building department is required. The project proposes a detention vault
to address the flow control requirements. The following are items that will need
to be addressed as part of the Civil Construction Permit Application:
i. The detention system shall be located a minimum of 10 feet from any
adjacent building. Location of vault will need to be evaluated and
adjusted as needed to meet this requirement.
ii. Targeted area not able to be routed to the detention vault shall be
modeled as bypass area (i.e. unmitigated flow directed to the projects
downstream point of compliance).
iii. Lid and access panels for the detention vault shall be located outside of
the ADA paths and stalls.
b. Conveyance, RSWDM Core Requirement #4: All new conveyance systems
constructed as part of the project must be sized to RSWDM standards for the total
tributary area (onsite and offsite) that the storm systems serve.
i.Utility Separation will need to be provided. This includes separation
between storm drainage mains the proposed detention vault.
c. Water Quality, RSWDM Core Requirement #8: Based on the commercial use of
the project, Enhanced Basic Water Quality Treatment is required. The project TIR
identifies approximately 3,000 SF of Pollution-Generating Impervious Surface
(PGIS) and is exempt from Water Quality Requirements.
i.A Leachable Material Covenant will be required to be submitted as part
of the Civil Construction Permit Application in order to eliminate the
roof material from as a source of PGIS.
d. Onsite BMPs, RSWDM Core Requirement #9: Appropriate on-site BMPs will be
required to help mitigate the new runoff created by this development. A
preliminary drainage plan, including the application of on-site BMPs, has been
included with the land use application. The final drainage plan and drainage
report must be submitted with the civil construction permit application.
i. Final evaluation of the application of on-site BMPs to the maximum
extent feasible will be completed during civil construction permit
review. The applicant may be required to apply additional on-site BMPs

in order to meet the minimum requirements outlined in Core
Requirement #9. Permeable Pavement and other BMPs may be possible,
see comments noted under the Geotechnical Report above.
3. A Construction Stormwater General Permit from Department of Ecology will be required
since grading and clearing of the site exceeds one acre. A Stormwater Pollution
Prevention Plan (SWPPP) is required for this site.
4. Surface water system development fee is $0.720 per square foot of new impervious
surface, but not less than $1,800.00. The project is proposing to add approximately 0.353
acres of impervious surface. The estimated total SDC for surface water is $11,071.21. This
is assessed based on the final approved civil construction plans and payable prior to
issuance of the construction permit.
TRANSPORTATION/STREET COMMENTS
1. The proposed development fronts along Davis Avenue South, a Commercial-Mixed Use
Industrial Access Street, along the northwest portion of the property. Existing right-of-
way (ROW) width varies between approximately 50 feet to 58 feet. To meet the City’s
complete street standards for a Commercial-Mixed Use Industrial Access Street,
minimum ROW is 69 feet for a 2-lane roadway. Per City code 4-6-060, half street
improvements shall include a pavement width of 36 feet (18 feet from centerline), a 0.5-
foot curb, an 8-foot planting strip, an 6-foot sidewalk, 2-foot clear zone between back of
sidewalk and right of way, street trees and storm drainage improvements. The developer
is required to provide the right of way and street frontage improvements on the half side
of street fronting the subject development site. Right of Way dedication will be required
in order to encompass the required roadway improvements and clear zone.
a.The applicant submitted a modification as part of the land use application to
maintain the existing roadway improvements fronting the subject property.
Community and Economic Development Staff in conjunction with Pubic Works
Transportation staff have reviewed the street modification request. Staff
recommends approval of the modification given that the existing street section
meets the transportation needs for connectivity, pedestrian access, and
separation between vehicular and pedestrian movements.
2. Gibson Traffic Consultants, Inc. (GTC) provided a transportation memorandum dated May
29, 2019. The site generated traffic volumes were calculated using data from the Institute
of Transportation Engineers (ITE) Trip Generation Manual, 10th Edition, (2017). Based on
the calculations provided, the proposed development (73 assisted living units) would
average 190 new daily vehicle trips. Weekday peak hour AM trips would generate 14 new
vehicle trips, with 9 vehicles entering and 5 vehicles leaving the site. Weekday peak hour
PM trips would generate 19 new vehicle trips, with 7 vehicles entering and 12 vehicles
existing the site. Increased traffic created by the development will be mitigated by
payment of transportation impact fees. In accordance with City standards, the project
produces less than 20 PM Peak Hour Trips therefore a full traffic Impact Analysis is not
required.
3. Paving and trench restoration shall comply with the City’s Trench Restoration and Overlay
Requirements. The document is available at:

nd%20Street%20Overlay%20Requirements.pdf
4. Payment of the transportation impact fee is applicable on the construction of the
development at the time of application for the building permit. The current rate of
transportation impact fee is $2,109.46 per bed for Senior Housing. The estimated total
impact fee for 73 assisted living units is $153,990.58. The transportation impact fee that
is current at the time of building permit application will be levied.
5. Transportation Concurrency under separate cover.

RENTON POLICE COMMENTS:
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 will need 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 crimi nal 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. 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 aid police in making contacts with unwanted individuals on the property if they are
observed vandalizing or stealing building materials.
COMPLETED COMPLEX
Each residential unit should have solid core doors, preferably metal or solid wood, with
peepholes. The doors should have heavy-duty deadbolt locks with a minimum 1-½” throw and
installed with 3” wood screws. Any external storage areas should also have solid wood or metal
doors, with deadbolts and latch guards installed.
Sliding windows and glass patio doors should have secondary locks installed to restrict
movement. These secondary locks need to be placed into the top or bottom of the window
frames to restrict movement. Simply placing a sturdy, fitted dowel in the window tracks may
be adequate.
Security lighting should be installed along sidewalks, foyers and pathways. Each assisted living
unit should have individual designators clearly posted with numbers or letters at least 6” in
Security Survey Page 2 of 2 LUA19-000158
height and of a color contrasting with the building. This will assist emergency pe rsonnel in
locating the correct location for response.
Latch guards should be installed on any and all doors leading from the outside in. Where egress
might be an issue, bar-releases can be installed to meet Fire Code requirements. This would
include any storage or maintenance rooms, etc. Pedestrian doors leading to the outside should
require a code to enter and exit for security purposes in regards to your customer base.
Any separate resident storage units should have latch guards and deadbolts inst alled.
Dumpster locations should be secured within their own housing and well lit. If possible,
creating a dumpster location that can be secured for facility use, but accessible for waste
management is recommended.
It is recommended that the commercial areas be monitored with recorded security alarm
systems installed. It’s not uncommon for businesses to experience theft and/or vandalism
during the hours of darkness. An auxiliary security service could be used to patrol the property
during those times. It is important to direct all foot traffic towards the main entrance of the
buildings. Any alternative employee entrances should have controlled access doors to prevent
trespassing.
Landscaping should be installed with the objective of allowing visibility: not too dense or too
high. Too much landscaping will make residents and employees feel isolated, and will provide
criminals with concealment to commit crimes such as burglary and vandalism.
Based upon the needs of this facility’s residents there will be staffing onsite 24/7. Parking lot
for both visitors and especially employees will need to be well lit to deter prowling activity.
Miscellaneous
I recommend the developer have a Crime Prevention Representative conduct a security survey
for this facility once it is near completion.
