SUBJECT: Chick-fil-A Parking Lot and Drive-Thru Expansion
351 & 375 Rainier Ave S
LUA 21-000440
The applicant is requesting to modify the approval of LUA18-000619, Chik-Fil-A, to modify the parking area and drive-thru
stacking lanes. The number of stalls would increase from 42 onsite and five (5) offsite parking stalls to 58 onsite stalls with
the five (5) offsite stalls. The stacking lanes would be expanded to accommodate 29 vehicles, up from 15. Associated site
improvements include modification of stormwater infrastructure and additional landscaping and pedestrian
improvements. The existing vacant building (former Firestone building) would be demolished while the existing Chik-Fil-A
building would remain as-is. I have reviewed the application for the Chick-fil-A Parking Lot and Drive-Thru expansion at
351 & 375 Rainier Ave S APN(‘s) (000720-0126 & 000720-0149) and have the following comments:
EXISTING CONDITIONS
The combined sites are approximately 1.285 acres in size and are rectangular in shape. The existing Chick-Fil-A site (south)
is 0.93 acres in size and consists of a newly constructed restaurant located near the south property line with an associated
parking lot and 2-lane drive-thru on the northern part of the site. The site is accessed from Rainier Ave S on the northeast
property line and the Fred Meyer parking lot to the southwest. The existing Firestone site (north) is 0.355 acres in size
and consists of an existing (now unoccupied) vehicle service and repair facility and is accessed from Rainier Ave S on the
east property line and to the north from the O’Reilly Auto Parts Parking Lot.
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 Rainier Ave S (see Water plan no. W-3430) that
can deliver a maximum total flow capacity of 4500 gallons per minute (gpm). There is also an existing 8-inch
water main located in Renton Center Way SW (see Water plan no. W-2165) that can deliver a maximum capacity
of 2,000 gallons per minute. The approximate static water pressure is 70 psi at the elevation of 26 feet. The site
is located within Zone 2 of an Aquifer Protection Area. There is an existing domestic water service that serves
each parcel, there is 1.5-inch domestic water meter serviced from 8” water main to the newly constructed
restaurant a 1-inch domestic water meter serviced from the 12” water main in Rainier to the unoccupied
commercial building on 351 Rainier Ave S. The restaurant site is also served by a 6-inch fire lateral and ¾-inch
irrigation meter.
Sewer Wastewater service is provided by the City of Renton. There is an existing 8-inch PVC wastewater main located
on the west of the property where it flows southwest paralleling Renton Center Way SW (see City plan no. S -

2293). City records indicate that the existing 307 and 351 properties connect to the onsite main, howe ver,
details are limited due to the age of the buildings. The newly constructed building located at the 375 property
has a sewer connection at MH5703 located onsite.
Storm There is an existing storm drainage system in Rainier Ave S (see City plan no. R-3430). There is also an existing
on-site conveyance and water quality system that was constructed as a portion of the Chick-Fil-A development
in addition to an unmapped storm drainage conveyance system located within the existing Firestone parking
lot. The site falls within the City’s Flow Control Standard (Exist Peak). The site falls within the Black River
drainage basin.
Streets Rainier Ave S is a Principal Arterial Street with an existing right of way (ROW) width of approximately 125 feet
in front of the Chick-Fil-A site and 119 feet in front of the Firestone site as measured using the King County
Assessor’s Map. Current street frontage improvements include curb and gutter, five-foot planter strip and an
eight-foot sidewalk on both sides of the street. The frontage of the Firestone site contains an eight-foot sidewalk
adjacent to the curb but does not contain a planter strip.
WATER COMMENTS
1. The development is not proposing an addition to the existing building and only parking lot and drive-thru
expansion, therefore, the proposal is not subject to a water system development charge (SDC) fees.
2. There is an existing 1-inch water meter that serves the Firestone building from Rainier Ave S.
a. The existing 1-inch service shall be removed and decommissioned as a portion of the demolition of the
existing building located at 351 Rainier Ave S.
3. Additional water system development charges and water meter charges will apply if a landscape irrigation meter
is required and is based on the size of the meter.
SEWER COMMENTS
1. The is not proposing an addition to the existing building and only parking lot and drive-thru expansion,
therefore, the proposal is not subject to a wastewater system development charge (SDC) fees.
a. The existing side sewer serving the 351 Rainier Ave S building shall be cut and capped during
demolition of the existing building. City records are limited as to the nature of this connection and it
shall be the Developer’s responsibility to determine where the system connects and if it serves
upstream properties. In the event upstream properties are served by the existing side sewer, onsite
cleanouts to grade shall be provided at bends and an easement provided if they do not already exist.
2. The parking lot and drive-thru location proposes to relocate the existing trash enclosure to a new location to
accommodate the new parking spaces and driving lanes.
a. The trash enclosure shall connect to the existing sewer system located onsite via an area drain
connected to an oil/water separator prior to entering the City’s sewer system.
STORM DRAINAGE COMMENTS
1. The development is subject to a system development charge (SDC) for stormwater. The 2022 SDC for
stormwater is $0.84 per square foot of new impervious surface area, but not less than $2,100.00. The fee that
is current will be charged at the time of construction permit issuance.
2. A preliminary Drainage Plan and Technical Information Report (TIR), dated August 11, 2021, was submitted by
Barghausen Engineering with the Land Use Application. Based on the City of Renton’s flow control map, the site
falls under Flow Control Duration Standards (Existing Peak Conditions) and is located within the Black River

drainage basin. The development is subject to a 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. The detention, water quality and conveyance shall be designed in
accordance with the RSWDM that is current at the time of the civil construction permit application. The
applicant has proposed to connect to the City of Renton’s storm drainage system located within Rainier Ave.
a. The development currently is showing that there is less than 0.15 CFS increase due to the proposed
development and they are exempt from flow control. During the review of the final TIR the applicant will
need to ensure that flow control standards are being met as outlined in the 2017 RSWDM.
b. The applicant is proposing to use the modular wetland and oil/water separator that was constructed
with in order for the project to meet the water quality requirements. The modular wetland is located
within the parking lot in the center of the lot prior to connecting into the City of Renton system located
within Rainier Ave S.
c. On-site BMPs satisfying Core Requirement #9 will be required for the site. On-site BMPs shall be
evaluated in order of preference by feasibility as described in Section C.1.3 of the 2017 RSWDM. All
targeted impervious area to the maximum extent feasible shall be conveyed to an On-site BMP.
Applicant proposes to use pervious concrete sidewalk facilities where available.
d. The following stormwater improvements are required and shall be discussed or revised within the TIR:
i. All Core Requirements and Special Requirements must be evaluated within the TIR.
ii. Evaluation of the existing stormwater water quality and oil control facilities is required to
ensure that the existing facilities can provide adequate water quality and oil control for the
additional pollution generating impervious surfaces. The final Technical Information Report
shall take into account this additional area and if determined that the facilities need to be
upsized, the final engineering plans will need to be updated to reflect the changes.
iii. Feasibility of On-site BMPs must be based on the feasibility criteria established for the specific
On-site BMPs noted in Appendix C of the 2017 RSWDM. A feasibility analysis of the On-site
BMPs must be provided with the TIR.
1. The TIR notes that On-site BMPs shall be applied to 10% of the site with 65%
impervious coverage. This statement only applies when infiltration and basic
dispersion have been deemed infeasible or have been applied to the site to the
maximum extent feasible and Reduced Impervious Surface Credit, Native Growth
Retention Credit, and the Tree retention credit are being applied to the site.
2. Treatment Liners may be required for infiltration facilities within Aquifer Protection
Zone 2 per RSWDM Section 1.3.6 (Special Requirement #6).
3. Bio-retention facilities with underdrains do not satisfy the requirements of Core
Requirement #9 per RSWDM Section C.2.6.1 Note 5 and may not be used as On-site
BMP Sizing Credit for Core Requirement #3 Flow Control facility sizing or exemption
per RSWDM Section 1.2.9.4.
4. The On-site BMPs if sized per the LID Performance Standards must meet 8% of the 2-
year peak flow up to the 50-year peak flow if LID Performance Standards are being
used.
3. A Geotechnical Report, dated June 21th, 2018, completed by Terracon for the site has been provided. The
submitted report describes multiple layers of soil characteristics. Approximately the first 1 to 2 feet contain
imported fill. Below the surface there is approximately 10 to 12 feet of very loose silt and sand combination with
a high water table that increase the susceptibility to static settlements and liquefactions in the event of an
earthquake.

a. An updated Geotechnical Report shall be provided with the Civil Construction Permit Application
evaluating the onsite soils of the 351 property.
b. The Geotechnical report recommends that all drainage facilities, including splash blocks, be located a
minimum of 10 feet away from the building.
c. Infiltration testing may be required in order to determine feasibility of the On-site BMPs required in
order to meet Core Requirement #9 of the RSWDM.
d. The TIR states that full infiltration is not recommended on site due to high groundwater elevation
during the winter months. However, Groundwater was detected between 8’ and 12’ in borings
collected on May 31st, 2018 per Geotechnical Report. Provide documentation from geotechnical
engineer supporting the infeasibility of full infiltration for this reason.
TRANSPORTATION/STREET COMMENTS
1. The project is not proposing an addition to the existing building or occupancy, therefore, an increase in traffic to
and from the site is not anticipated. Since the project will not result in additional trips, additional transportation
impact fees are not warranted.
2. The proposed development fronts Rainier Ave S along the east property line(s). Rainier Ave S is classified as a
Principal Arterial Road. The existing right of way (ROW) width is approximately 125 feet in front of the Chick -Fil-
A site and 119 feet in front of the Firestone site as measured using the King County Assessor’s Map. To meet the
City’s complete street standards for Error! Reference source not found. streets, minimum ROW is 125 feet.
a. A dedication of approximately 6’ (pending final survey) where the right -of-way line jogs around the
existing Firestone building and sidewalk will be required for this project based on matching the frontage
improvements that were constructed by the City’s Rainer Ave S corridor project.
b. The existing curb line along Rainier Ave S will remain in its current location and a 5-foot wide planter
strip with 8-foot wide sidewalk and 2-foot wide clear space behind the sidewalk is required. Based on
final survey and layout, the right-of-way dedication may vary to accommodate the proposed
improvements.
c. The existing restaurant driveway cut along Rainier Ave S is required to be removed and replaced with
planter and sidewalk. Where the project is proposing to re-use a portion of the existing Rainier Ave S
driveway cut for the 351 property, the driveway shall be rebuilt to provide a minimum of 5 feet between
the cut and the north property line. The current proposal show s the northern driveway being moved
south and further than the required 5 feet. In the event of a site plan change or driveway cut relocation,
a modification may be required.
d. The proposal shall maintain internal vehicular connection with the 307 property to the north.
e. A photometric analysis of the existing street and pedestrian lighting along the 351 property frontage
shall be provided during the Civil Construction Permit review process clearly showing that the relocated
street lighting and removal of Firestone building will meet City lighting standards. Additional
pedestrian and/or relocation of arterial light standards may be necessary to meet the requirements
based on the analysis.
3. A traffic analysis dated August 13, 2018, was provided by TENW with an addendum dated July 2, 2021. The site
generated traffic volumes were calculated using data from the Institute of Transportation Engineers (ITE) Trip
Generation Manual, 10th Edition, (2017). The addendum reviewed the existing access points along Rainier Ave S
(Chick-Fil-A and Firestone accesses) and noted that there will be an overall benefit by removing one of the two
existing accesses through driveway cut consolidation and expanding the onsite drive-lanes and queuing lanes.
a. Applicant will need to ensure that there will not be a backup onto Rainier Ave S at any time.
4. Paving and trench restoration within the City of Renton right of way shall comply with the City’s Street
Restoration and Overlay requirements.
