Construction Mitigation Description
Construction is proposed to begin in July 2018 and end in October 2018. Construction will occur during daylight
hours, Monday through Friday. Transportation and access to the project site will be from North 41st Street and
Lake Washington Boulevard North. No fill or excavation will take place below the ordinary high water mark of
May Creek. All proposed repair and retrofit work will occur to existing trestle structures and no change in the
bridge footprint will occur. Cleared areas will be limited to the stabilized construction entrance, access road and
wheel wash area. High visibility fencing will be installed to protect existing vegetation. Temporary erosion and
sediment control measures (TESC) and appropriate construction best management practices (BMPs) such as silt
fencing, will be used during construction to minimize erosion. Potential stormwater runoff from the construction
activity will be intercepted by installed erosion control methods.
