Construction Mitigation Description
To Whom It May Concern:
The City of Renton (City) has contracted Century West Engineering Corporation (Century West) to
complete engineering design for the Renton Municipal Airport Taxiway A Rehabilitation and Associated
Improvements (project). As part of the project design services, Century West is assembling the
Environmental (SEPA) Checklist Submittal, and this Construction Mitigation Description.
Please provide a written narrative addressing each of the following:
a. Proposed construction dates (begin and end dates)
Phase 1 Construction: May-September 2025
Phase 2 Construction: June-August 2026
b. Hours and days of operation
Normal construction hours will be Monday-Friday, 7:00am-5:00pm. Occasional Saturday and Sunday
work from 7:00am-5:00pm, only if needed to stay on schedule.
For 6 weeks of Phase 1 Construction and 6 weeks of Phase 2 construction, work will be performed that
requires a runway closure. The runway closure work will occur from Monday-Friday for three (3) two-
week periods over the duration of each phase of construction. The runway closure work will occur from
12:00pm-10:00pm each weekday and not on weekends.
c. Proposed hauling/transportation routes
Haul routes will be via Airport Way, Perimeter Road, and the vehicle drive lane within the Airport fence.
Refer to plans for reference.
d. Measures to be implemented to minimize dust, traffic and transportation impacts, erosion, mud, noise,
and other noxious characteristics

The Contractor will be required to control all dust, erosion control, and Foreign Object Debris (FOD)
throughout the course of the work. The contract will have specific bid items for the Contractor to control
FOD. Transportation impacts will be limited to when the fire waterline connection is made on Perimeter
Road. Construction entrances will be installed to limit tracking mud onto public right-of-way.
e. Any special hours proposed for construction or hauling (i.e. weekends, late nights)
As work progresses, the Contractor may elect to perform weekend work to stay on schedule. Work would
occur from 7:00am-5:00pm on weekends, if required.
For 6 weeks of Phase 1 Construction and 6 weeks of Phase 2 construction, work will be performed that
requires a runway closure. The runway closure work will occur from Monday-Friday for three (3) two-
week periods over the duration of each phase of construction. The runway closure work will occur from
12:00pm-10:00pm each weekday and not on weekends.
