City of Renton Shoreline permit, local Bldg and electrical permits
State Environmental Policy Act Review
Give brief, complete description of your proposal, including the proposed uses and the size of the
project and site. There are several questions later in this checklist that ask you to describe certain
aspects of your proposal. You do not need to repeat those answers on this page. (Lead agencies may
modify this form to include additional specific information on project description
Project Description
Apron R is on the south shore of Lake Washington, north of Buildings 4-41, 4-20,
4-81, 4-82 and
4-83. The Apron R project site is adjacent to the Lake Washington shoreline and
within City of
Renton shoreline jurisdiction. The project area is approximately 0.39 acres within
the 200-foot shoreline buffer.
West of the Boeing parcel is a city park, the Cedar River, and Renton Municipal
Airport.
Commercial properties are to the south and east. Lake Washington is directly
north of the Boeing parcel.
The Boeing parcel is zoned Urban Center 2 (UC-2) and is currently used for airport
manufacturing by Boeing. The proposed project will not change the existing use
of the project.
No off-site improvements are proposed.
Approximately 1,500 feet of the shoreline along Apron R consists of a pile-
supported concrete.
deck, concrete bulkhead, sheet-pile bulkhead and riprap bulkhead. Vegetation is
limited to
Washington Department of Natural Resources restoration area and a mitigation
area that was.
planted with native species (see Section 4.2 of Lake study.). The site does not
contain any wetlands or other special features.
Soils on the site are classified as Urban Land (NRCS n.d). Stormwater drainage
flows away from Lake Washington, into existing inlets which routes flows to the
existing stormwater system.
The proposed development will add 4 and replace 2 crew shelters and add 7 tool
cabanas and
relocate 2 tool cabanas to Apron R.
The following is a summary of new and replacement structures:
One new 12-foot by 40-foot crew shelter
One replacement 12-foot by 56-foot (replacing an existing 12’x30’) crew shelter.
Three new 10-foot by 30-foot crew shelters

shelter.

One relocated 10-foot by 10-foot tool cabana.
One relocated 10-foot by 20-foot tool cabana.
One 8-foot by 10-foot Disaster Supply tool cabana
The crew shelters will be prefabricated wood structures on elevated steel chassis.
The tool
cabanas will be repurposed shipping containers constructed of cold-formed steel
sitting directly on the concrete pavement. The crew shelters will be secured to the
existing post-installed.
mechanical or epoxy anchors into the existing concrete paving.
Exterior lighting is included on the crew shelters. All lighting will be directional
and is oriented away from the lake. A lighting study completed for Boeing
indicates that there will be no lighting will spill into the lake.
The project does not include any grading or placement of fill materials. No trees
or vegetation
will be removed. The proposed buildings will not alter any views because they are
single-story structures with relatively small footprints. The completed project will
be consistent with the
existing structures and industrial use of the site.
The estimated construction cost and estimated fair market value of the proposed
project is $719,801.40.
12. Location of the proposal. Give sufficient information for a person to
understand the precise location of your proposed project, including a street
address, if any, and section, township, and range, if known. If a proposal
would occur over a range of area, provide the range or boundaries of the
site(s). Provide a legal description, site plan, vicinity map, and topographic
map, if reasonably available. While you should submit any plans required by
the agency, you are not required to duplicate maps or detailed plans submitted
with any permit applications related to this checklist.
Refer to Neighborhood Map, and Site Map for project location.
