PROJECT NUMBER: LUA25-000146, CAE
PROJECT NAME: Rolling Hills Creek Pipe Rehabilitation
PROJECT MANAGER: Mariah Kerrihard, Associate Planner
OWNER/APPLICANT/ Jared McDonald, City of Renton
CONTACT: 1055 S Grady Way, Renton, WA 98057
PROJECT LOCATION: 905 Talbot Rd S, Renton, WA 98055
North Parking Lot of 1400 Talbot Rd S, Renton, WA 98055 (APN 1923059090)
PROJECT DESCRIPTION: The applicant, City of Renton Public Works Surface Water Utility, is proposing
a Critical Areas Exemption (CAE) as part of a maintenance project to repair approximately 406 linear feet
(406’) of damaged stormwater pipes that convey water from Rolling Hills Creek. This project is categorically
exempt from Environmental (SEPA) Review as a maintenance activity, consistent with WAC 197-11-800(3).
The project includes three (3) segments of pipe lining and encompasses two (2) sites. The first site, located
at 905 Talbot Rd S, is situated south of S Renton Village Pl and west of Talbot Rd S (Attachment A). The second
site is located south of S Renton Village Pl and east of Talbot Rd S in the north parking lot of 1400 Talbot Rd S
(APN 1923059090). These sites are zoned Commercial Arterial (CA) and are designated Commercial Mixed
Use (CMU) in the Comprehensive Plan Land Use Map. The purpose for the proposed rehabilitation work, as
detailed in the Project Narrative (Attachment B) and the Site Plan (Attachment A), involves repairing 66 linear
feet (66’) of 24-inch (24”) concrete stormwater pipe and 340 linear feet (340’) of 42-inch (42”) corrugated
metal stormwater pipe (CMP) that is deteriorated or failing. This would be achieved by inserting a Cured-in-
Place Pipe (CIPP) liner into each identified pipe by means of a trenchless method. The scope of work includes
installing temporary stormwater diversion as necessary in upstream structures to bypass flow to
downstream structures for each pipe segment. As a result, the storm structures may be required to be
plugged and/or require coffer dams.
Following the stormwater diversion, the pipes would be cleaned, debris removed, and any voids filled with
grout. Subsequently, a 42-inch (42”) CIPP liner would be installed along the entire length of the designated
pipes using a trenchless method. If temporary diversion is necessary for the 42-inch (42”) lining, it would be
removed from the upstream structure upon completion. Finally, a 24-inch (24”) CIPP liner would be installed
along the entire length of the designated pipes, which may also require temporary stormwater diversion in
the upstream structure to bypass flow to the downstream structure. It is anticipated that a stormwater
diversion would be required due to Rolling Hills Creek flowing through pipes 118951, 128514 and 128467.

Access to the site would remain via the existing entrance off S Renton Village Pl and Talbot Rd S. According
to City of Renton (COR) Maps, there are high seismic hazard areas, high landslide hazards, high erosion
hazards, sensitive and protected slopes, and a piped Type F stream (Rolling Hills Creek) mapped on the site.
CRITICAL AREA: High Erosion Hazards, High Seismic Hazard Areas, High Landslide Hazard,
Type F Stream (Rolling Hills Creek), Sensitive and Protected Slopes,
EXEMPTION JUSTIFICATION: Renton Municipal Code, Section 4-3-050C.3.e.ii. Maintenance, Operation,
and Repair of existing Parks, Trails, Roads, Facilities, and Utilities, and the Construction of New Trails:
Normal and routine maintenance, operation and repair of existing parks, trails, streets, roads, rights-of-way
and associated appurtenances, facilities and utilities where no alteration or additional fill materials will be
placed other than the minimum alteration and/or fill needed to restore those facilities or to construct new
trails to meet established safety standards. The use of heavy construction equipment shall be limited to
utilities and public agencies that require this type of equipment for normal and routine maintenance and
repair of existing utility structures and rights-of-way. In every case, critical areas and required buffer impacts
shall be minimized and disturbed areas shall be restored during and immediately after the use of
construction equipment.
CRITCAL AREA EXEMPTION FINDINGS:
The proposed development is consistent with the following findings pursuant to RMC section 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 and 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 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 get a Hydraulic Project Approval (HPA) from the Washington Department of Fish
and Wildlife (WDFW). A 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 specified by industry
standards or applicable Federal agencies or scientific principles;
Staff Comments: The project site encompasses critical areas such as high seismic hazard
areas, high landslide hazards, high erosion hazards, sensitive and protected slopes, and a
piped Type F stream (Rolling Hills Creek), however, the proposed pipelining work is designed
to avoid impacts to these sensitive areas. As outlined in the Project Narrative (Attachment B),
the trenchless lining method would not impact the soil. Furthermore, the project would
adhere to industry standards using best management practices, as illustrated in the Site Plan
(Attachment A), to ensure minimal impact during all phases of work.
iii. Impacts are minimized and, where applicable, disturbed areas are immediately restored;
Staff Comments: The proposed improvements are within existing stormwater pipes and
there are no other proposed alterations to the pipe segments outside the aforementioned
work, therefore no anticipated new impacts to the high seismic hazard areas, high landslide

hazards, high erosion hazards, sensitive and protected slopes, or the piped stream mapped
on-site.
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 existing 42-inch (42”) and 24-inch
(24”) stormwater pipes through the non-invasive application of CIPP lining. Given that no
excavation or underground work would occur, no disturbance to any water body or buffer is
anticipated within the project sites.
v. If a hazardous material, activity, and/or facility that is exempt pursuant to this Section has a
significant 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-specific data.
Staff Comments: Not applicable. It is not anticipated that the proposal would result in
hazardous materials infiltrating groundwater as the proposed work is within existing
stormwater pipes. The scope of work includes constructing temporary stormwater bypasses
as needed during construction to divert stormwater around trenching and pipe installation
activities while maintaining drainage of upstream stormwater, as described in the Site Plan
(Attachment A). It is anticipated that by inserting a CIPP liner into each pipe, existing drainage
patterns would be maintained.
DECISION: An exemption from the Critical Areas Regulations is hereby Approved .

Project Narrative
Rolling Hills Creek Pipe Rehabilitation Project
SWP-27-4297
PROJECT OBJECTIVE
Repair 340 LF of 42” CMP and 66 LF of concrete pipe via CIPP Lining.
PROJECT BACKGROUND & DESCRIPTION
The City of Renton Surface Water Utility has identified three segments of pipe that have been damaged
or are starting to fail due to age. The Surface Water Utility has setup a CCTV review program that
videos stormwater pipes. CCTV of assets 128514, 118951, and 128467 have been reviewed for pipe
deterioration and cracking. Each of these damaged sections convey water from Rolling Hills Creek.
The Rolling Hills Creek Pipe Rehabilitation Project is a maintenance project to ensure that further
deterioration is stopped by inserting a CIPP liner into each 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 340 LF of 42” CMP Pipe and 66 LF of 24” Concrete Pipe adjacent Talbot Rd S.
Easements: No easement is required due to the work being entirely in the City of Renton right-of-way.
Surveying and Geotechnical Investigation: No survey was conducted. Information for design drawings
were based on City of Renton GIS data. No geotechnical report has been generated and is not required
because the project is lining existing 24” and 42” pipes 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 Rolling 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 are three segments (manhole to manhole) of pipe lining. A total of 66 LF of 24”
concrete pipe and 340 LF of 42” CMP to be lined. Each segment should take approximately 1 day to
complete for a total of 3 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.

Construction July 1, 2025 - August 30, 2025
STAKEHOLDER ENGAGEMENT
Community: The Rolling Hills Creek Lining project will have limited impact to nearby
residents/community members due to project location and time required to complete project. Lining
the pipes should only take a couple days. When lining work is to be performed the City of Renton
project manager and inspector will work with the contractor to notify all residents and community
members impacted. They will also ensure the adequate access to properties are maintained.
Other Agencies: City of Renton - Maintenance, City of Renton – CED, WA Department of Fish and
Wildlife
Private Utilities: There are no anticipated impact private utilities. No excavation or underground work
will be conducted. Project is lining an already existing 42” and 24” pipe. Utility locates will be
responsibility of contractor to ensure that their method of accessing the project site and performing
lining of pipe will not impact other utilities.
STAFFING
Project Management: The project manager is Jared McDonald, Surface Water Utility.
Mapping: Based on City GIS.
Geotechnical Investigations: Not required.
Design Engineer: The design engineer is Jared McDonald from the Surface Water Utility.

Fish Passage & Diversion Screening Inventory Database
Report Cover Sheet
The following report is extracted from the Washington Department of Fish and Wildlife’s (WDFW) Fish
Passage and Diversion Screening Inventory Database (FPDSI). WDFW makes every attempt to keep these
reports in sync with FPDSI; however, the dynamic nature of the data and workflows associated with
maintaining the database may result in short-term differences.
Users are encouraged to contact WDFW to discuss appropriate use of the data and how we can assist
with fish passage barrier removal or inventory. Please visit the Fish Passage web site for contact
information at: https://wdfw.wa.gov/species-habitats/habitat-recovery/fish-passage/about
Disclaimers:
• Data presented here represent a snapshot observation of conditions in a dynamic environment
that is subject to change. Fish passage data are also collected from a variety of agencies and
sources. Therefore, WDFW makes no guarantee concerning the data’s content, accuracy,
completeness, or the results obtained from use of the data. WDFW assumes no liability for the
data represented here.
• These data are not an attempt to provide you with an official agency response as to the impacts
of your project on fish and wildlife.
• Note that some fish passage features, habitats or species may occur in areas not currently
known to the WDFW Fish Passage division, and may not be reflected in this database. A lack of
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.
