Permit Number B17006124
2801 NE Sunset Blvd, Renton, WA
1. Pre-Application Meeting Summary: Waived.
2. Waiver Form: Attached.
3. Land Use Permit Master Application Form: Attached.
4. Fees: Check has been included.
5. Project Narrative:
The Site is located at 2801 NE Sunset Blvd in Renton, Washington. The Site is situated in
the NW quarter of Section 9, Township 23, Range 5. The site is located at an elevation of
approximately 100 feet above mean sea level (amsl). The subject site is flat with a regional
topographic slope to the west-northwest. The Site is zone Center Village (CV) and is
within the Commercial and Mixed Use (CMU) designation.
Site improvements include a 20,219 square foot convenience store and a fueling canopy
and fuel dispensers. The Site has been historically used as a service station and the current
fuel system consists of three steel USTs (two 12,000-gallon and one 10,000-gallon) and
two dispensers.
Boring logs from the Phase II Environmental Site Assessment in 2012 indicated the
subsurface soils are comprised of sand with some clay underlain by sandy clays beginning
at approximately 25 feet below ground surface (bgs). Groundwater at the Site has been
observed in onsite monitoring wells at between approximately 55 feet and 60 feet bgs.
The existing USTs will be removed from their original UST cavity and the excavation will
be backfilled with a commercial borrow source with ¾ minus (or similar) rock. The existing
UST cavity is approximately 28 feet by 33 feet with an estimate depth of 12 feet bgs. No
grading will be completed. The existing UST cavity will be backfilled and paved to match
the existing parking area. It is estimated that approximately 400 cubic yards of ¾-minus
rock will be used to backfill the UST excavation. The fueling canopy and all ancillary UST
piping will also be removed. The estimated project costs are approximately $90,000.
The project work will utilize standard heavy equipment and will the project will take
between 1 and 2 weeks to complete. Work will be done during normal business hours
(730 to 540) during the standard work week. No job trailers or other temporary structures
will be used.
During the project, no new structures will be installed, no trees will be removed. Once the
project is complete, the only visual change will be the removal of the existing fueling
canopy.
6. Environmental Checklist: Attached.
7. Rezone, Variance, Modification or Conditional Use Justification: Not applicable.
8. Density Worksheet: Waived.
9. Construction Mitigation Description:
The construction dates will be based on the City of Renton’s acceptance of this land use
and SEPA application. We anticipate that the project will commence within 30 days of
approval by the City of Renton. We anticipate that the project will take between 1 and 2
weeks to complete. As noted above, project work will commence Monday through Friday
between the hours of 7:30 am and 5:30 pm.
The limited soils removed from the UST excavation will be stockpiled on plastic and
bermed as necessary to minimize stormwater runoff. When possible, we will direct load
soils into the transportation vehicles.
Due to the small nature of this project, we do not anticipate that any traffic control or
traffic impacts will be necessary. We anticipate that the project work will be limited to
the UST nest area and fueling canopy. All equipment will be staged onsite. Limited in
bound and outbound trucks will be needed for the removal of the USTs, soil over burden
and the importation of backfill. The final source for the backfill and the disposal location
for the USTs has not been finalized and will be based on field conditions and
subcontractor availability.
