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

Next Steps:
● Additional physical suitability metrics (open space

parking capacity)
● Motivational metrics at block level (average resident age,
average assessed home value)
● Web platform?
Next Steps:
● Finalize design and

● Full-scale prototype
● Assembly process
