14. Parcel Suitability Metrics
Completed to date for EPA:
1. Physical suitability of parcels (lot capacity, necessity of parking, etc.)
2. Accessibility of basic services by block
3. Historical friendliness of blocks to development
Next steps
● Additional metrics
● Expanding to, and beyond, San Mateo County

23. Percentage of basic services accessible within...
5 min biking 10 min biking5 min driving 10 min driving
10 min walking 20 min walking 10 min transit 20 min transit

Next Steps:
● Additional physical suitability metrics (open space
constraint, corner setbacks, more robust rear-line setback,
parking capacity)
● Motivational metrics at block level (average resident age,
average assessed home value)
● Web platform?
Next Steps:
● Finalize design and
engineering
● Construction
documentation,
permitting
● Full-scale prototype
● Assembly process
