Picture:

2. Project goals/Design Requirements
Connect U-district station to Everett
Maximize
potential users
Minimize
Impacts to existing recreational infrastructure
Environmental impacts
Cost

3. Design factors
In order to achieve project restraints, data gathered for:
Grade
Wetlands
Population Density
Parks
Trails
Express stops (Light rail)

4. GIS Analysis Buffer Clips Erase Slope calculation Used constraints to
narrow possible routes
from U-district
to Everett.

5. Option 1

6. Option 2

7. Option 3

8. Recommendations Option 1 Option 2 Option 3
This minimizes changes to existing infrastructure, follows a low slope, and runs through locations where people come from/go to.
Option 2
Fails to follow population density as well as Option 1.
Option 3
Fails to follow low slope constraints.
