Thank you for your comments on the Longacres Campus Master Plan (LUA25-000100). Your comments
have been added to the o)icial file for consideration and you have been added as a party of record. In
addition, your comments will be provided to the applicant and to EA, the City’s consultant for the
Environmental Impact Statement (EIS). As part of the project review, open space considerations will be a
significant part of the review.
Please feel free to contact me directly, if you have additional questions.

Public Health - Seattle & King County (Public Health) addresses health threats to our communities, helps
ensure access to quality healthcare, and promotes healthy community conditions where everyone can
achieve optimal well-being. The following comments and recommendations are based on information
from the SEPA checklist for this proposed action and additional information regarding health risks to
people in King County.
Based on the SEPA 202502300 checklist, the Longacres Campus Master Plan includes:
Parcel subdivision - adding residential, commercial, or retail units, square footage, and/or uses,
including 3,000 residential units, 1,400,000 square feet of commercial space, and 6,500 parking spaces.
Neighborhood conditions for the location of this proposed action include:
· High levels of access to regional trails
· Low access to public open spaces
· Low tree canopy cover
· High proximity to high-speed transit
· High pollution exposure burden
Health conditions of residents in this neighborhood include:
· High social vulnerability rating (CDC SVI)
· High asthma prevalence (BRFSS)
· High COPD prevalence (chronic obstructive pulmonary disorder)
· High obesity prevalence
Regarding opportunities for this project to contribute to the health and well-being of future site
occupants and neighbors,
· Given the proximity to frequent transit service and entrances to the Regional Trails Network,
consider:
o Limiting on-site vehicle parking and compensating with su)icient indoor, secure,
convenient, ground-floor storage with easy access for visitor and resident bicycles,
strollers, and other micro-mobility devices.
o Promoting visibility for and safe and easy access to transit or ride-share pickup locations.
· Given the low amount of tree canopy coverage in the vicinity of this project, consider adding
landscaping features, additional trees, and other vegetation to reduce heat gain, increase
shading, and support biodiversity.
· Given the limited public open spaces in the vicinity of this project, consider incorporating
su)icient public recreation and green space amenities into the project site design and
landscaping plan.
· Given the higher exposure to air pollution in the vicinity of this project site, consider mitigation
measures that may include increasing site vegetation and improving indoor air quality through
careful placement of air intakes and increasing air filtration levels in HVAC systems that exceed
building code minimum requirements.
This site development proposal may result in land use conflicts, as sensitive building occupants of an
adjacent medical o)ice may be exposed to air and noise pollution of and vehicle tra)ic to/from industrial
uses. To avoid and mitigate potential health impacts of adjacent use conflicts, additional considerations
should be given to vehicle and pedestrian access, ventilation and odor control, building placement and
orientation on the site, and landscaping features.
