Last week we heard from planning staff from Burien, SeaTac, and Des Moines who did the painstaking work of combing over the documents included in the Port of Seattle’s DEIS for the Sustainable Action Master Plan (SAMP), which will have one of the most significant impacts on our community since the third runway project. The Port's DEIS covers 31 projects over 24 documents and is over 6,500 pages, so a big shout-out to our city staff for this work, and for collaborating with neighboring cities to help inform the public about what they found.
Because they discovered significant concerns, they hosted this meeting to help inform residents and facilitate a robust response through public comment. I can't express enough how important this is for our region, and we need to spread this message far and wide to leverage our voices in this moment to facilitate mitigation measures.
We've been granted another month to do so, so let's use it.
NEW DEADLINE for Public Comment Aug 20th, 5pm
Here are the following topics to help guide your written comments on what the experts have found as deficiencies:
📍The DEIS does not go far enough in analyzing transportation impacts. That includes traffic to and from the airport on SR509 and 518
📍The DEIS defers critical mitigation to later stages for environmental contaminants, habitat and wetland protections, and overall environmental impacts.
📍The DEIS does not fully measure impacts to noise and air pollution or define mitigation strategies.
📍The DEIS doesn’t show its work on calculating land use impacts to demonstrate impacts to neighborhoods, parks, and community resources.
📍The DEIS fails to prove that hazardous material impacts are not significant.
