Scores are not bell-curved. Percentiles and expected scores provide context without changing the underlying model.
Explain this score
Where did the 41 come from? Each weighted contribution against a neutral 50 baseline. Green = pushed up; red = pulled down.
Sum of contributions = the headline score. A negative bar means that dimension dragged the park below the city-wide neutral baseline.

Jacobs reading
Tradeoffs
- 19 nearby towers cast wind and shadow without contributing canopy — passive surveillance is plentiful but human-scale comfort is not.
Typology classification
Classified as Urban Plaza: 556 m², paved (0% canopy), 77.2 buildings/100 m
Edge Activation
Within 100 m of the park edge: 28 active uses (restaurant, retail, transit_stop, community, cafe) and 4 dead/hostile uses (parking_lot). Active edges keep "eyes on the park" through the day; parking lots, blank institutional walls, rail and highway frontages drain street life.

Connectivity
Connectivity blends paths, intersections, transit, entrances, and edge density. This park has 0 mapped paths/walkways and 7 sidewalk segments within 50 m; 8 street intersections within 100 m; 41 transit stops within a 400 m walk; 0 estimated access points across ~102 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
No amenities recorded — score is 0 until inventory is loaded.

Natural Comfort
Natural-comfort components for this park: 0.0% estimated tree canopy; 1 city-mapped trees inside the polygon (1.0/ha). Reading: exposed. Source coverage: street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
79 buildings within 25 m of the park edge (44 mid-rise, 16 low-rise, 19 tower); avg edge height 24.9 m (~8 floors); 77.2 buildings per 100 m of 102 m perimeter — strong frontage density; edges lean tall but still framed; 19 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 44 mid-rise edge buildings.

Border Vacuum Risk
Border-vacuum factors within 50 m of the park: parking_lot, parking_lot, parking_lot. Jacobs warned that highways, rail, parking lots and blank institutional edges act as "vacuums" — they suppress foot traffic and isolate the park from its neighbourhood.

Tell us how this park feels
We measure structure (canopy, edges, connectivity). You measure feeling. Both matter — and disagreement is itself useful civic data.
What would improve this park?
Generated from the weakest measured dimensions — a starting point, not a prescription.
- Add or open more entrances and improve sidewalk continuity around the park. More permeability means more spontaneous use.
- Diversify what people can do in the park — playground, washroom, water, shade, performance, sport, garden — even small additions raise this score.
- Increase canopy and reduce paved area. Shade and water features extend usable hours and seasons.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
