Construction Mitigation Description
The following provides a narrative for the items requested in the construction mitigation description as
part of the City of Renton Grade and Fill Permit application for the South Renton Transit Center Site
Remediation project. The site remediation project does not require the use of cranes.
Proposed construction dates
Construction is proposed to begin as early as July 15, 2022 and be complete on, or about, October 31,
2022.
Hours and days of operation
Working hours and days of construction would vary but would adhere to the City of Renton’s regulations
to control construction noise, which restricts non-residential construction noise on weekdays to the
hours of 7:00 a.m. to 8:00 p.m., and on Saturdays to the hours of 9:00 a.m. to 8:00 p.m. Construction
noise is prohibited on Sundays.
If an unanticipated reason arises, and construction activities are required at night or on Sundays, Sound
Transit would apply for a construction noise variance from the city of Renton.
Proposed hauling/transportation routes
The South Renton Transit Center site has existing driveways/site access off of Rainier Avenue S and S
Grady Way. Both Rainier Avenue S and S Grady Way are City of Renton designated haul routes for trucks
over 26,000 pounds gross vehicle weight.
Access to the site is from I-405 and SR 167, continuing straight/north onto Rainier Ave S, and right/east
onto the site.
Access from the site would be by exiting right/west onto S Grady Way, turning right/north onto Rainier
Avenue S, and then left/west onto SW Sunset Boulevard/SR 900 to I-5. SW Sunset Boulevard/SR 900 is
also a City of Renton designated haul route for trucks over 26,000 pounds gross vehicle weight.
No special hours are proposed for construction or hauling. As noted above, project construction is
anticipated to comply with Renton’s permitted construction hours.
Best Management Practices
The following Best Management Practices (BMPs) will be developed and implemented by the
Contractor, as required, during construction to minimize dust, erosion, mud, and noise. The project’s
traffic control plan, described below, identifies measures that will be implemented to reduce traffic and
transportation impacts.
• Develop a Temporary Erosion and Sediment Control Plan (TESCP), including measures such as
catch basin protection.
• Spray exposed soil with water or other dust palliatives to reduce emissions and deposition of
particulate matter.

• Cover all trucks transporting materials, wet materials in trucks, or provide adequate freeboard
(space from the top of the material to the top of the truck) to reduce or avoid windblown
deposition of particulate matter during transportation.
• Provide wheel washes to remove particulate matter that vehicles would otherwise carry off site
to decrease deposition of particulate matter on area roadways.
• Remove particulate matter deposited on paved, public roads to reduce mud and resultant
windblown dust on area roadways.
• Route and schedule construction trucks to reduce delays to traffic during peak travel times to
reduce secondary air quality impacts caused by a reduction in traffic speeds while waiting for
construction trucks.
• Place quarry spall aprons where trucks enter public roads to reduce mud track out.
• Require appropriate emission control devices on all construction equipment powered by
gasoline or diesel fuel to reduce carbon monoxide and nitrogen oxide emissions in vehicular
exhaust.
• Prohibit prolonged construction vehicle idling.
• Ensure construction equipment uses high‐grade engine exhaust silencers and engine‐
casing sound insulation.
• Minimize the use of generators.
• Decontaminate construction equipment at the end of each day, in accordance with a
decontamination plan.
• Follow the project’s Archeological Finds specification requirements during excavation activities,
including having a qualified archaeologist respond to potential inadvertent discoveries of
cultural resources.
Preliminary traffic control plan
Project grading and fill activities would all occur on the South Renton Transit Center site. Further, it is
anticipated that, during project activities, the contractor would stage the necessary equipment and
materials on the site. Temporary lane closures on adjacent roadways would not be required.
The number of trucks entering and exiting the site would be expected to vary over the course of
construction. The volume of trucks anticipated for hauling contaminated materials or bringing clean
backfill to the site would not affect the current level-of-service on Rainier Avenue S, SR 167, I-405, or
other adjacent local roads.
