KING COUNTY EASTSIDE INTERCEPTOR SECTION 2 REHABILITATION – PHASE II
TIER 2 TEMPORARY USE PROJECT NARRATIVE AND JUSTIFICATION
PROJECT NARRATIVE
Project name, size and location of site:
The name of the Project is the King County Eastside Interceptor Section 2 Rehabilitation - Phase
II (ESI2). The Project would consist of the rehabilitation of approximately 3,900 linear feet of
the 96-inch reinforced concrete wastewater pipe and eight (8) 48-inch diameter maintenance
holes mostly located within the Logan Avenue N. right-of-way between Lake Washington Blvd.
N. and Burnett Avenue N. (see Figure 1).
The project is needed due to severe corrosion of the pipeline as a result of exposure to
hydrogen sulfide gas. To rehabilitate the pipeline, sewer flow would be diverted via a
temporary bypass system and the pipeline would be rehabilitated in place using an in-situ liner
method called Linabond. The Linabond system results in a polyurethane coating inside of the
pipe to prevent further corrosion and can be installed using the existing maintenance holes
with the pipe in the dry.
Existing wastewater flows from upstream of the in-pipe work area would be pumped into a
bypass system to allow the Linabond system to be installed. Minimal local flows from side
sewer connections within the work area would continue to flow under the installation platform.
The bypass consists of the installation of high-density polyethylene (HDPE) piping that would
include three (3) 24-inch lines. The anticipated bypass pipeline route totals 4,200 feet. Most of
the bypass line would be located above ground either side by side or in a rack (see Figure 2).
Approximately 1,200 feet of trenched temporary piping would be located underground where
access to adjacent properties needs to be maintained (see Figure 3). There is also one
maintenance hole (R02-04) that was paved over and would need to be located and restored
before the lining work can occur.
At the upstream end of the Project, there would be an excavation (aka North Pit) to access the
existing pipe. A suction trench would be located downstream of maintenance hole RO2-08 at
the northern end of the alignment within the 200-foot segment of the pipeline previously
rehabilitated with Linabond. The top of the ESI2 pipeline would be exposed, and a window
would be cut from the top of the pipe to install the bypass pump suction piping (see Figure 4).
To shore the excavation, sheet piles, walers, and beams would be used to produce watertight
shoring. The soils within the excavation and within its vicinity would be chemically grouted to
further seal the excavation and provide structural stability. The North Pit would be
approximately 62 feet long by 17 feet wide and 9 feet deep.
2
The North Pit staging area will also consist of the bypass pumps and ancillary facilities. This
includes: 8 primary and 2 backup electric driven pumps; a utility meter, transformer and
transfer switch; a mobile diesel generator for backup power; two job trailers; and odor control
measures (see Figure 5). There may also be a Baker Tank in the event it is necessary to dewater
the excavation pit. The staging area also includes a parking area and material and equipment
storage area. At the southern end of the Project, another small excavation (aka South Pit)
would be dug to reconnect the bypass line. This excavation will be approximately 12 feet long
by 12 feet wide and 6 feet deep. There will also be a second staging area located in the Boeing
parking lot.
Land use permits required for proposed project:
• Tier 2 Temporary Use permit
• Noise Variance
• Work Hour/Day Variance
Zoning designation of the site and adjacent properties:
The project site and surrounding area is zoned Urban Center.
Current use of the site and any existing improvements:
The current use is a sewer line that consists of a 96-inch pipe located underground mostly in
the Logan Avenue N. right-of-way. The project starts at its northern end on Logan Avenue N.
near the intersection of Lake Washington Blvd. N and Garden Avenue N. The pipeline
alignment then follows Logan Avenue N. towards the southern end of the project where the
pipe crosses under a Boeing parking lot, and terminates in the Burnett Avenue N. right-of-way
nears its intersection with N. 6th Street.
The project will rehabilitate the sewer pipeline that has experienced severe corrosion from
contact with hydrogen sulfide gas in the wastewater.
Special site features:
The project is located in a high seismic hazard area.
Soil type and drainage conditions:
The soils in the project area are a mixture of fill and alluvium. The fill typically consists of silty
sand with varying amounts of gravel. Alluvium is located beneath the fill and consists of
interbedded sand with varying amounts of silt. The fill varies in thickness from nine to 13 feet.
The project occurs in an area that is almost 100 percent covered by impervious surface, thus
drainage from stormwater runoff is captured in the city’s stormwater collection system. It is not
anticipated that there would be any drainage concerns given the limited soil disturbance and that
the design groundwater level is at 9 feet below the surface.
3
Proposed use of property and scope of the proposed development:
There is no change in the proposed use of the property, which is to transmit wastewater
underground to the wastewater treatment plant.
Access:
Access to the project site is on Logan Avenue N, N. 6th Street, and Burnett Avenue N. There
would also be two temporary construction easements acquired for the project.
Proposed off-site improvements:
There are no off-site improvements proposed.
Total estimated construction costs:
The estimated construction cost of the project is $411,157.16.
Estimated quantities and types of materials involved for fill and excavation:
Total excavation:
• North Pit: 9,450 cubic feet
• South Pit: 900 cubic feet
• Bypass pipe trenches: 33,600 cubic feet (1,200 lineal feet @ 7 feet wide and 4 feet
deep average)
• Maintenance Hole 04: 50 cubic feet (5 feet x 5 feet square and 2 feet deep)
• Total: 44,000 cubic feet
• All excavations would be backfilled with the native material originally removed.
Number, type and size of any trees to be removed:
It is not anticipated that any trees would be removed. The notes on the construction plans
state that no trees shall be damaged or removed without prior approval from the City of
Renton.
Any land to be dedicated to the city:
There would be no land dedications.
Proposed job shacks:
Two temporary job trailers would be placed in the north staging area.
Any proposed modifications being requested:
Yes, the Tier 2 Temporary Use permit is being requested to establish two staging areas for the
project (see Figure 3). One at the north end and one near the south end. The northern staging
area (North Pit) is currently being used as a storage area for Boeing and is fully fenced. It would
$311,010.00.
4
be used for the pumping operation and job headquarters with parking for construction staff.
The southern staging area is located north of the Boeing parking lot and will be used to stage
equipment and material. King County has coordinated the use of these sites with the Boeing
Company.
JUSTIFICATION
1) The temporary use will not be materially detrimental to the public health, safety or welfare,
nor injurious to property or improvements in the vicinity of the temporary use.
The two staging areas would be fenced with a secure access for safety. The north staging area
would contain the job trailers, and construction staff that would monitor the pumping
operation would also ensure that the public is kept away from the operation.
The project would not affect other property or improvements in the vicinity as the operations
would be contained on the temporary use sites. Once the project is completed, the two sites
would be restored to their original conditions.
2) Adequate parking facilities and vehicle ingress and egress are provided to serve the
temporary use and any existing uses on the site.
The north and south staging areas would accommodate parking for construction staff and
vehicles and there would be adequate ingress and egress from Logan Avenue N.
3) Hours of operation of the temporary use are specified, and would not adversely impact
surrounding land uses.
The project construction would occur 24 hours a day, 7 days a week, and a variance request has
been made to accommodate this schedule. The aggressive schedule would minimize the
disruptions to surrounding land uses by reducing the amount of time that traffic and residences
are affected. It would allow the work to be coordinated so that road closures could occur
during nighttime hours and project work timed to not adversely affect access during shift
changes at Boeing.
4) The temporary use will not cause nuisance factors such as noise, light, or glare, which
adversely impact surrounding land uses.
The south staging area would produce some nuisance impacts as it is located very close to
single-family residences (the closest residences are approximately 50 feet and 150 feet from
the south excavation). Nighttime lighting would be necessary, but directed downward to limit
lighting effects. Noise would be generated from the movement of equipment and materials
and use of a generator, some of which could be minimized by limiting nighttime work in this
area and use of noise barriers.
Similarly, the north staging area would also generate noise and nighttime lighting effects, but
residences (apartments) are located farther away (approximately 525 feet) and these
5
apartments are newer structures with better insulation to minimize outside noise. The project
would implement several measures to control noise from the pumping operation including the
use of electrical pumps and noise barriers, which would not generate sound levels that exceed
the noise standards.
5) If applicable, the applicant has obtained the required right-of-way use permit.
Yes, there will be approval for right-of-way work obtained as part of the civil construction
permit. The City indicated that a separate right-of-way permit would not be necessary.
CONSTRUCTION MITIGATION DESCRIPTION
Proposed Construction Dates
The project is estimated to occur between March 1, 2019 and November 30, 2020.
Hours and Days of Operation
Construction would take place 24 hours a day and 7 days a week. A variance has been
requested for nighttime and weekend construction.
Proposed Hauling/Transportation Routes
Logan Avenue N. and Southport Drive N. would be used to access I-405.
Measures to be Implemented to Minimize Dust, Traffic, Transportation Impacts, Erosion, Mud,
Noise and Other Obnoxious Characteristics
The earth work is very minimal and the staging areas are impervious surface. The only likely
source of dust or erosion/mud would be from the soil stockpiles from the excavation. There
would be a silt fence erected around the piles and they would be covered with weighted down
plastic so that no dust, mud or erosion occurs.
Traffic would be controlled through the use of flaggers, signage, barriers, detours, etc.
Construction would be coordinated with Boeing shift changes so as not to impede access. A
traffic control plan is attached to this application.
The project would employ the use of electric pumps to minimize noise and will erect noise
barriers around the pumping operation in the north staging area.
Security lighting would be directed downward to limit light effects.
The contractor will also be required to prepare an environmental mitigation plan addressing:
site maintenance, waste disposal, street cleaning, dust, odor, light and noise control, traffic
control, water quality protection, tree and vegetation protection, spill prevention and spill
response, and historic/cultural resources protection (including an inadvertent discovery plan).
Any Special Hours Proposed for Construction or Hauling
6
Yes, construction is proposed during weekends and evening hours.
Preliminary Traffic Control Plan
A formalized traffic control plan (TCP) would be prepared consistent with the provisions of the
Washington State Manual on Uniform Traffic Control Devices and submitted to the city for
review (the TCP is in process). The TCP is anticipated to employ a number of measures to
control traffic including signs, barriers and flaggers. Some examples of signage include: Start
Road Work, End Road Work, One Lane Road Ahead, Road Work Ahead, Detour, Shoulder
Closed, Lane Closed, Sidewalk Closed, Road Closed to Through Traffic (local traffic only), Road
Closed Ahead, Detour Ahead, and Be Prepared to Stop. Signs with images such as arrows, lane
configuration diagrams, and pictures of flaggers would also be used. A number of barrier
devices may be employed such as traffic cones, striped wood Type 3 barricades, jersey barriers,
and yellow tape. Flagger and sign placement would be coordinated with the city inspectors.
The TCP would include conditions of approval. For example, changes in traffic control devices,
detours, or major road, bike lane, or sidewalk closures would trigger notifications to adjacent
property owners, emergency providers (fire, police, and ambulance), and other affected parties
(school buses, shift changes at Boeing, etc.) in advance of the work. Accommodations would be
made for pedestrian and cyclists when sidewalks, bike lanes or walkways would be impeded.
Any other conditions applied to the project by the city would be incorporated into the TCP.
