Every ProperQi™ Score starts at a base of 70. Each factor below adds or subtracts points based on nearby map data:

Typical terrain0
No strong elevation pattern relative to the facing direction.
Water very close (flowing)+10
Water feature within 25m -- flowing water (river or stream) -- classical Form School treats moving water as especially auspicious, associated with "moving wealth" chi.
Power line nearby-11
Power line within 23m -- treated as a sha chi (negative energy) source in Form School, weighted by both distance and how disruptive this type of feature is generally considered.
Major road exposure-11
A major road (highway/primary class) runs within 60m -- meaningfully more traffic noise and exposure than a typical residential frontage.
Green space very close+4
Park or wooded land within 42m -- nearby greenery is associated with living, growing chi.
Facing S (estimated)+3
This is a simplified general Compass School estimate (inferred from the nearest road frontage -- override this if you know the actual entrance direction), not a full Xuan Kong Flying Star reading -- a real analysis also depends on the occupants' Kua number and the building's construction period.
School in the area+2
A school is within 360m -- some Feng Shui traditions associate proximity to a place of learning with "wenchang," or scholarly luck, a modest positive. Practical factors like drop-off/pick-up traffic and playground noise aren't separately scored here.
FEMA flood zone A-8
This address falls within FEMA-mapped flood zone A, a Special Flood Hazard Area with meaningfully elevated flood risk.

Numeric Address4/5
Favorable number -- Based specifically on Chinese numerological tradition (not a universal Feng Shui principle), where certain digits carry auspicious or inauspicious associations from their sound in Mandarin/Cantonese. House number 2019 contains "9" (associated with longevity). Treat this as a small cultural-flavor rating, not a physical-site assessment like the factors above.
A separate cultural-tradition rating, not included in the ProperQi™ Score above.
