PROJECT LOCATION: Parcel No. 7399200870 and City Right-of-Way near 1900 Rolling Hills Ave SE
(APN 7399200410)
PROJECT DESCRIPTION: The applicant, Jared McDonald, on behalf of City of Renton Public Works Surface
Water Utility, is proposing a maintenance project for an ageing stormwater pipe for Thunder Hills Creek. This
project is located in the right-of-way (ROW) near 1900 Rolling Hills Ave SE and extends into an undeveloped
parcel (APN 7399200870) that the Thunder Hills Creek flows through. This site is zoned Residential-8 (R-8) and is
in the Benson Community Planning Area. The proposed pipe rehabilitation project, as described in the Project
Narrative (Attachment A), is to repair a ninety-nine-foot (99’) long pipe that is twenty-four inches (24”) wide with
a cured-in-place pipe (CIPP) lining. The existing pipe is a corrugated metal pipe (CMP) and it shows deterioration
and erosion along the bottom of the pipe. A CIPP liner would extend the lifetime of the pipe by sealing cracks and
damages without requiring any excavation or soil disturbance. Construction is estimated to take a couple of days
to complete. This project is categorically exempt from SEPA review as a maintenance activity, consistent with
WAC 197-11-800(3). According to City of Renton (COR) Maps, a moderate coalmine hazard, moderate landslide
hazard, regulated slopes, and a Type F stream (Thunder Hills Creek) are mapped on site.
CRITICAL AREA: Moderate Coalmine Hazard, Moderate Landslide Hazard, Regulated Slopes, and
Type F Stream (Thunder Hills Creek)

required buffer impacts shall be minimized and disturbed areas shall be restored during and immediately after
the use of construction equipment.
CRITICAL AREA EXEMPTION FINDINGS:
The proposed development is consistent with the following flndings pursuant to RMC 4-3-050C.2.d:
i. The activity is not prohibited by this or any other provision of the Renton Municipal Code or State
or Federal law or regulation.
Staff Comments: Maintenance and repair of existing utilities are exempt activities which are
permitted within geologic hazard areas, habitat conservation areas, streams and lakes, and
wetlands according to the City of Renton’s Critical Areas Regulations. This project would be a
permissibly exempt activity conducted within a geologic hazard area and a stream. This decision
does not exempt the applicant from any other agency approvals needed to do the proposed work.
For example, Washington State law (RCW 77.55) requires hydraulic projects in or near state
waters to obtain a Hydraulic Project Approval (HPA) from the Washington Department of Fish and
Wildlife (WDFW). An HPA ensures that construction is done in a manner that protects fish and
their aquatic habitats.
ii. The activity will be conducted using best management practices as specifled by industry
standards or applicable Federal agencies or scientiflc principles.
Staff Comments: The project site encompasses critical areas such as a moderate coalmine
hazard, moderate landslide hazard, regulated slopes, and a Type F stream (Thunder Hills Creek).
The proposed pipelining work is designed to avoid impacts to these sensitive areas. As outlined
in the Project Narrative (Attachment A), the trenchless lining method would not impact the soil.
Furthermore, in the project’s Site Plan (Attachment B), the notes detail how the project would
adhere to industry standards using best management practices to ensure minimal impact during
project construction.
iii. Impacts are minimized and, where applicable, disturbed areas are immediately restored.
Staff Comments: The work that would be conducted is the minimally impacting maintenance
option for this stormwater pipe rehabilitation. No alterations outside lining the existing pipe are
proposed; therefore, no additional impacts to the critical areas present are anticipated.
iv. Where water body or buffer disturbance has occurred in accordance with an exemption during
construction or other activities, revegetation with native vegetation shall be required.
Staff Comments: The proposal entails the rehabilitation of an existing 24-inch (24”) stormwater
pipe through the non-invasive application of CIPP lining and the application does not require any
excavation or soil disturbance. Additionally, this work is intended to be done in dry weather with
precautions for erosion – both of which would further avoid any potential water body or buffer
disturbance.
v. If a hazardous material, activity, and/or facility that is exempt pursuant to this Section has a
signiflcant or substantial potential to degrade groundwater quality, then the Administrator may
require compliance with the Wellhead Protection Area requirements of this Section otherwise
relevant to that hazardous material, activity, and/or facility. Such determinations will be based
upon site and/or chemical-speciflc data.
Staff Comments: It is not anticipated that the proposal would result in hazardous materials
infiltrating groundwater as the proposed work is within existing stormwater pipes. In precaution,
all dewatering water and runoff would be treated as needed before discharging downstream.

Project Narrative
Rolling Hills Ave SE Pipe Rehabilitation Project
SWP-27-4297
PROJECT OBJECTIVE
Repair 99 LF of 24” CMP via CIPP Lining.
PROJECT BACKGROUND & DESCRIPTION
The City of Renton Surface Water Utility has identified one segment of pipe that has been damaged or
is starting to fail due to age. The Surface Water Utility has setup a CCTV review program that videos
stormwater pipes. CCTV of asset 505717 has been reviewed for deterioration and erosion of the
bottom of pipe.
The Rolling Hills AVE SE Pipe Rehabilitation Project is a maintenance project to ensure that further
deterioration is stopped by inserting a CIPP liner into the pipe. This liner extends the life of the existing
pipe by sealing the cracks and other damages of the pipe.
FACILITY CONFIGURATION
CIPP Lining of 99 LF of 24” CMP across Rolling Hills AVE SE.
Easements: The majority of, work is being performed in the City of Renton right-of-way. There is an
existing easement in place on parcel 7399200870 that provides the city access to perform stormwater
maintenance on Thunder Hills Creek and the existing 24” CMP.
Surveying and Geotechnical Investigation: Parametrix established a survey for the base design. No
geotechnical report has been generated and is not required because the project is lining an existing 24”
pipe and will not be impacting the soil.
Design: The City of Renton Surface Water Utility has completed the design of the project internally.
Design elements included construction plans, specifications, and engineer’s cost estimate.
Environmental Review Permits: This project requires an HPA from WA Department of Fish and Wildlife
because the pipe being repaired conveys Thunder Hills Creek. A Critical Areas Exemption permit is
being requested. Lastly, this project is categorically exempt from SEPA because this is a maintenance
project per WAC 197-11-800 (3).
Construction: There is one segment (manhole to manhole) of pipe lining. A total of 99 LF of 24” CMP to
be lined. Each segment should take approximately 1 day to complete for a total of 1 days of lining
work. The work will consist of setting up at the upstream and downstream structure and installing the
new liner. Challenges will include access to the structures and traffic/pedestrian control.
PRELIMINARY COST ESTIMATE
Engineer’s Cost Estimate: $92,500

data does not necessarily indicate that a feature, habitat, or species are not present.
• Unauthorized attempts to alter or modify these data are strictly prohibited.
• Bankfull width measurements included in these reports should not be used for fish passage
crossing design. They are solely for assessment purposes.
• The barrier status reported in this document is based on the swimming abilities of adult
salmonids. Passabilities are a qualitative value, and should not be interpreted as a quantitative
calculation. Please see page 1-4 of the Fish Passage Inventory, Assessment and Prioritization
Manual for further clarification: https://wdfw.wa.gov/publications/02061
• EXIF data presented with Image Reports may be erroneous due to camera battery failures and
resetting of camera clock functions.
Abbreviations:
Most abbreviations in this report are defined in the Quick Reference Tables of the Fish Passage Inventory, Assessment, and Prioritization Manual. Additional commonly used abbreviations are defined as follows:
NFB = no potential salmonid use, BB = both banks, LB = left bank looking downstream, RB = right bank looking downstream, US
or U/S = upstream, DS or D/S = downstream, WSDrop = water surface drop, BFW = bankfull width, OHW = ordinary high water,
SLW = scour line width, CMP = corrugated metal pipe, Qfp = fish passage flow, V&D = Velocity and Depth, ROW = Right of Way
The FPDSI database often uses default values such as ‘-99.99’ or ‘-999’ to represent null values.
