Construction Mitigation Description
9. Construction Mitigation Description: Please provide a written narrative addressing each
of the following:
Proposed construction dates (begin and end dates);
Response: Construction within Renton may begin as early as Spring/Summer 2018. It
is expected that construction will take between 6 to 9 months.
Hours and days of operation;
Response: Construction hours are typically between 7:00 am to 6:00 pm, Monday
through Saturday. PSE will comply with work hours and conditions of issued
permits. Any unique construction circumstances requiring variations to these days
and times will be discussed in advance of work within the City. Night work is
expected related to stringing conductors over major highway crossings, arterials,
and high traffic corridors. This is a common permit condition imposed by
Washington State Department of Transportation (WSDOT). Weekend and off-hours
work (including Sunday) may be necessary to transport material or equipment
during periods of low traffic to complete the project in a timely manner.
Proposed hauling/transportation routes;
Response: Haul routes will be determined by truck type, load length, and gross
vehicle weight. Ideally, routes would be the shortest distance to the laydown area,
material storage site, or construction site. Routes would use major highways and
multi-lane roads as much as possible to minimize residential disturbance.
Temporary access routes to poles within PSE’s utility corridor will generally follow
previously established access trails and routes. Therefore, little cutting or filling will
be required, if any. Small amounts of quarry spalls/gravel placement might be
necessary to stabilize portions of exiting routes and entrances at road crossings. The
proposed access to poles have been identified, but may need to be modified to
allow for delivery of extra-long loads, such as certain pole types or extra-large
equipment.
Measures to be implemented to minimize dust, traffic and transportation impacts,
erosion, mud, noise, and other noxious characteristics;
2
Response: PSE will use careful planning to prevent dust, traffic and transportation
impacts, erosion, mud, noise, and other noxious characteristics to the extent
reasonable. PSE has worked to locate the upgraded poles near existing accessible
routes to minimize construction traffic impacts. Where these impacts cannot be
avoided, PSE will minimize impacts by using best practices such as water spraying,
traffic control and timed deliveries, BMPs, and efficient work planning. There will be
at least one full-time Washington State CESCL on site during construction.
If helicopters were used, PSE and their contractor would comply with the local and
FAA congested air permit conditions and notification requirements, including Renton
Municipal Airport. As these are specialty helicopters and work techniques, the work
would likely be scheduled weeks in advance. The public notice and awareness
outreach would be flexible and could be communicated in advance.
Following completion of construction activities, restoration BMPs such as mulching
and/or placing jute matting may be implemented along with reseeding, planting of
new shrubs and trees and other appropriate stabilization techniques.
Any special hours proposed for construction or hauling (i.e. weekends, late
nights); and
Response: In some situations, night or weekend work may be conducted to
minimize traffic and neighborhood impacts, meet schedule needs, or as a
requirement of a jurisdiction or government agency. See more details above.
Preliminary traffic control plan.
Response: PSE will apply for street use permits with Renton and WSDOT. The traffic
control plans will follow guidelines set forth by the underlying right-of-way owner.
Traffic control will be needed for deliveries, construction, or pedestrian traffic in
areas where work is adjacent to a foot path such as sidewalk or trail. In the case of
foot paths, temporary signage and barriers will be used to keep pedestrians at a safe
distance from the work area.
If your project requires the use of cranes, please contact the City’s Airport Manager at
425-430-7471 to determine whether Federal Aviation Administration (FAA) notification
will be required.
Response: PSE will use cranes to set poles and may use helicopters in topographically
challenging locations or to minimize construction time. PSE will coordinate with the
City’s Airport Manager to determine FAA or other notification and communication
requirements.
