November 8, 2017 Serial Letter 001
City of Renton
1055 South Grady Way
Renton, Washington 98057
Subject: Gene Coulon Park Maintenance
City of Renton Staff,
The letter is a request for the City of Renton to issue exemptions from SEPA review and from
Shoreline Substantial Development Permit requirements for the Gene Coulon Park Maintenance
project.
The City of Renton proposes eight maintenance tasks on structures across Gene Coulon Park,
including the following:
1.Trestle Bridge:
Bridge repair will consist of cutting the top portion of a damaged pile to stop the transfer of
rot to the superstructure. The pile will not be pulled or replaced due to a lack of easy access
points. Structural members will be installed to re-support the existing framing.
2.Sailing Club Floats:
A float connection has been damaged and will be replaced using agency approved
supplemental floatation to correct the freeboard imbalance.
3.Ivar’s Deck Repair:
The timber decking will be removed and replaced with grated decking along with the
replacement of the corroding steel framing and pile caps. Additionally, the perimeter wave
skirt will be removed and replaced in part at Ivar’s with non-toxic materials as required by
the Aquatic Lands Lease with the Department of Natural Resources (Lease No. 22-086143).
Timber stringers will be replaced with steel stringers. The steel beams will be replaced and
coated with a durable coating system.
4.North Waterwalk Wave Skirt:
The north waterwalk perimeter wave skirt, consisting of treated timber, will be removed in
accordance with DNR lease requirements.
5.Transient Moorage Float:
The existing float will be demolished and replaced with a new float in the same footprint.
The existing gangways frames will be reused and the decking will be replaced with a grating
consisting of more open area, in accordance with DNR lease requirements.
6.Boat Launch Wave Barrier:
The boat launch wave barrier treated timber portions below the water-line and within the

DNR lease boundary will be replaced with non-toxic materials.
7.Boat Launch Pier:
As a result of loss of the protective coating and fungal decay, the damaged steel framing and
damaged timber piles will be repaired. The pile decay is located on the top of timber piles in
the 3-pile dolphin. Repairs to the dolphin will include removal of damaged timber sections.
8.South Waterwalk:
Grout between the waterwalk superstructure and the piles is missing in spots and will be
replaced.
The proposed work is also categorically exempt from SEPA review based on the criteria described in
WAC 197.11.800(3):
“The repair, remodeling, maintenance, or minor alteration of existing private or public structures, facilities or equipment,
including utilities, involving no material expansions or changes in use beyond that previously existing; except that, where
undertaken wholly or in part on lands covered by water, only minor repair or replacement of structures may be exempt
(examples include repair or replacement of piling, ramps, floats, or mooring buoys, or minor repair, alteration, or
maintenance of docks).”
The proposed work is also categorically exempt from Shoreline review based on the criteria described
in RMC 4.9.190(C)(3):
“Maintenance and Repair: Normal maintenance or repair of existing structures or developments, including damage by
accident, fire or elements. a. “Normal maintenance” includes those usual acts to prevent a decline, lapse, or cessation
from a lawfully established condition. b. “Normal repair” means to restore a development to a state comparable to its
original condition, including but not limited to its size, shape, configuration, location and external appearance, within a
reasonable period after decay or partial destruction, except where repair causes substantial adverse effects to the shoreline
resource or environment. c. Replacement of a structure or development may be authorized as repair where such replacement
is the common method of repair for the type of structure or development and the replacement structure or development is
comparable to the original structure or development including, but not limited to, its size, shape, configuration, location
and external appearance and the replacement does not cause substantial adverse effects to shoreline resources or
environment.”
Please see the attached JARPA for further project descriptions. The JARPA has been prepared to
meet the requirements of the federal and state agencies with jurisdiction over the project site. Thank
you for your consideration of this request. Should you require any additional information, please don’t
