Proposed Scope of Work
The Applicant is proposing a tenant improvement project to remove three (3) existing 12,000-gallon
underground storage tanks (USTs) and replace them with two (2) new USTs; one 15,000-gallon tank, for
the storage of unleaded fuel, and a 15,000-gallon dual/split tank, for the storage of premium unleaded
(7,000 gallons) and diesel fuel (8,000 gallons). New turbines will also be installed for each UST.
While no changes are proposed to the development footprint or site operations, the project does call for the
demolition/removal of concrete drive slabs beneath the fuel canopy and on top of the existing tank pit.
The Applicant proposes to demolish the existing fuel islands and sumps, remove the existing multi-product
dispensers and replace with new dispensers. Upon completion of the tank and dispenser installation, new
concrete slabs will be installed. Asphalt will be saw cut as needed, providing necessary trenching for new
piping to serve the newly-installed dispensers. Electrical conduits, breakers , and panel will be installed as
part of the new fuel distribution system. A new vent box and pipe rack will be installed along the west side
of the convenience store while a new air/water unit will be located adjacent to the existing trash enclosure
on the east side of the building.
Development Details
Site Features, Soil and Drainage: The site is relatively flat with gradual sloping (1% to 8%) from the
northwest to the southeast, from a peak of ± 467 feet along the west property line to ± 459 feet along the
116th Avenue S.E. frontage.
Preliminary research on soils indicates two (2) soil types are prevalent onsite: AgB and AgC Alderwood
gravelly sandy loam materials. These soil types are moderately well drained, but with a very low ability to
store water and are not considered to be hydric soils. No critical areas have been mapped onsite.
The stormwater design will be developed in compliance with the City of Renton Surface Water Design
Manual with amendments to the 2016 King County Stormwater Design Manual (KCSWDM). Full drainage
review is required since improvements are projected to exceed code requirements for new plus replaced

impervious surface. A Technical Information Report (TIR) will be prepared for permitting, providing a
conceptual drainage plan with supporting calculations and including the TIR's core and special
requirements are adequately addressed.

Tree Retention / Removal: The project will not impact existing landscape (trees, bushes, shrubs or
groundcover), thus no landscape plan is being provided. Any landscaping damaged during construction
will be replaced.
All development activity will be restricted to impervious surfaces. The project proposes to remove and
replace approximately 4,550 square feet of concrete and asphalt surfaces.
Access/Traffic: The project site is directly accessible to S.E. 168th Street and 116th Avenue S.E. via two
(2) full access driveways, a 29-foot wide driveway accessing S.E. 168th Street and a 40-foot wide driveway
accessing 116th Avenue S.E. The project will not increase parking stalls on site; however, one stall is being
allocated for new ADA/handicapped parking.
The site is directly accessible to public transit. Transit stops are located north and south of the site on 116th
Avenue S.E. and east of the site on S.E. 168th Street serving bus routes 102 and 906.
Right-of-Way Dedications: No right-of-way dedications will be required.
Proposed Modifications: No modifications are anticipated for this project.
Utilities: As a fully developed site, all required utilities are currently available through a variety of purveyors,
including, but not limited to, Puget Sound Energy (PSE) and Soos Creek Water and Sewer District
(SCWSD). Soos Creek staff have provided an e-mail confirmation regarding the current status of said
service; including copies of the original permits, a GIS reference and a copy of current utility billing.
