Construction Mitigation Description: Please provide 5 copies of a written narrative addressing each of
the following:
Proposed construction dates (begin and end dates)
Proposed construction dates are unknown and will be dependent upon permitting restrictions, fish
windows, seasonal rain conditions, and habitat restrictions for nearby nesting herons.
Hours and days of operation
Construction operations will be generally limited between Monday and Friday during an 8-hour
consecutive period between 7:00am and 6:00pm.
Any special hours proposed for construction or hauling (i.e. weekends, late nights)
Night, weekend and holiday work will not be permitted.
Proposed hauling/transportation routes
Haul and construction site access with be from Monster Road and Naches Avenue, depending on the
section of trail to be constructed.
Preliminary traffic control plan
Traffic control along Monster Road will generally include single-lane traffic and sidewalk closures using
flaggers and standard WSDOT Work Zone Traffic Control plans. Traffic control at Naches Avenue and
the trailhead will be limited to parking restrictions; this is a cul-de-sac and serves as parking for
infrequent trail users.
Measures to be implemented to minimize dust, traffic and transportation impacts, erosion, mud, noise,
and other noxious characteristics
Temporary erosion and sediment control measures from the King County Surface Water Design Manual
(2009), Appendix D, will be applied during construction to limit dust, erosion, mud, and noise and other
noxious characteristics of the construction.
