Dear Jill Ding,
Thank you for the opportunity to comment on the Thuman Residence to request a Shoreline Substantial
Development Permit, Environmental (SEPA) Review and a height modification for the construction of a
2-story 1,012 square foot detached accessory dwelling unit located at 13411 SE 151st St in Renton.
Based on the information provided and our understanding of the project and its APE, the Duwamish
Tribe would recommend an inadvertent discovery plan, especially if any groundbreaking activity occurs
below fill, topsoil or other impervious surfaces into native soil, particularly peat. This is an area that the
Duwamish Tribe considers culturally significant and has a High probability to have unknown
archaeological deposits. We note that there are 3 historical and ancestral Duwamish place names within
about a mile of the project location. The DAHP WISAARD predictive model indicates that an
archaeological survey is highly advised with a very high risk for encountering cultural resources.
We request that if any archaeological work or monitoring is performed, we would like notification.
Cultural and archaeological resources are non-renewable and are best discovered prior to ground
disturbance. The Tribe would also like the opportunity to be present if or when an archaeologist is on
site.
In addition, the Tribe strongly recommends only native vegetation be used for any proposed landscaping
to enhance habitat for fish and wildlife, and native avian life and native pollinators. The Tribe supports
observing critical area tracts and stream buffers to preserve any remaining wetlands and stream buffers.
Loss of wetland habitat is known to affect the viability of fish, water quality and increase the effects of
seasonal urban flooding.
We also strongly recommend that mature native trees in the APE are preserved. Mature trees can be of
profound cultural significance to the Duwamish Tribe and provide innumerable benefits for people,
climate, and wildlife. If a tree is suspected to be culturally modified, the Duwamish Tribe would like to be
notified and would like the opportunity to come to the site to ensure its protection.
Finally we request that any lighting be dark sky compliant to reduce light pollution. Darkened skies were
favorable conditions to practice traditional life pathways.
Thank you,
Duwamish Tribal Historic Preservation
