PROJECT NUMBER: LUA21-000131, SME
PROJECT NAME: 1139984 Kennydale Culvert Repair
PROJECT MANAGER: Jill Ding, Senior Planner

CONTACT: Jason Anglin
King County Parks
201 S Jackson St.
Seattle, WA 98104
PROJECT LOCATION: King County Parcel No. 3124059004, in the vicinity of 3223 Mountain View Ave N
PROJECT DESCRIPTION: The applicant is requesting a Shoreline Exemption to repair a sinkhole on King County
Department of Natural Resources and Parks (Parks) property (Parcel 3124059004) in the vicinity of 3233
Mountain View AVE. The sinkhole is in the middle of a driveway that serves two properties. The drain line
creating the sink hole has been inspected. The findings show the concrete pipe has broken allowing water to
escape its intended path and significantly reducing the capacity of the pipe. This leads to water both backing up to
the inlet and escaping out into the driveway surface. The applicant is proposing to replace the broken 12-inch
concrete drainpipe with a corrugated HDPE pipe and to add a type 1 catch basin to facilitate a proper connection
where the drain changes directions. The applicant also proposes to add a type 2 catch basin where the culvert
from under the trail connects to the new HDPE pipe. No in-water work will occur, and no critical areas will be
impacted by the project. This project is repair and maintenance and does not change drainage patterns or
stormwater discharge locations. The project site is located within the Shoreline Residential designation and Lake
Washington Reach E. Proposed work would occur approximately 87 feet from the ordinary high water mark
(OHWM).

EXEMPTION JUSTIFICATION/DECISION: An exemption from a Shoreline Management Substantial Development
Permit is hereby Approved with Conditions* on the proposed project in accordance with RMC.4.9190C
“Exemption from Permit System’ and for the following reasons:
Normal maintenance or repair of existing structures or developments, including damage by accident, fire or
elements. "Normal maintenance" includes those usual acts to prevent a decline, lapse, or cessation from a
lawfully established condition. "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 shoreline resource or environment. 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.
FINDINGS: The proposed development is:
i. Consistent with the policies of the Shoreline Management Act.
ii. Not Applicable to the guidelines of the Department of Ecology where no Master Program
has been finally approved or adopted by the Department.
iii. Consistent with the City of Renton Shoreline Mater Program.
*CONDITIONS OF APPROVAL:
1. The applicant shall obtain a stormwater permit prior to beginning construction. To apply for the permit,
please email PWpermitting@rentonwa.gov or apply online at permitting.rentonwa.gov/#/home.
