Jean Sibelius Square scores 45.9 / 100. Strongest dimensions: enclosure / eyes on park and connectivity. Weakest: edge activation (0). Border-vacuum risk is low. This score is a transparent reading of Jane Jacobs-style vitality factors — not a definitive judgment.

Explain this score
Where did the 46 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.
Why this park works
What limits this park
Most distinctive characteristic
Jacobs reading
Tradeoffs
- Connectivity (74) significantly outpaces natural comfort (39) — well placed in the city but offers little shade or ecological respite.
- The park is enclosed by buildings (96) but the surrounding streets are quiet (edge activation 0) — frame without animation.
- Strong physical conditions (score 46) but weak observed activity signals (10) — the model says this should work, but events, mentions, and counters say it isn't being used at the level the urban form would predict.
- High connectivity (74) coexists with little programming evidence — easy to reach, but no recurring civic life detected.
Typology classification
Classified as Civic Square: name flags as civic square + 86 buildings frame the edge. Secondary read: Urban Plaza (4811 m², paved (0% canopy), 31.4 buildings/100 m).
Edge Activation
Within 100 m of the park edge: 0 active uses (none) and 0 dead/hostile uses (none). 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 4 mapped paths/walkways and 19 sidewalk segments within 50 m; 13 street intersections within 100 m; 22 transit stops within a 400 m walk; 8 estimated access points across ~274 m of perimeter. edge density is healthy — no superblock penalty. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
3 distinct amenity types in the park (picnic, playground, washroom). Diversity, not raw count, drives the score so a park with many distinct activity types can outrank a larger park that repeats the same use.

Natural Comfort
Natural-comfort components for this park: ~5.6% effective canopy (0.0% from contiguous tree polygons + scattered tree density); nearest waterbody ~1060 m; 8 city-mapped trees inside the polygon (8.0/ha). Reading: exposed. Source coverage: waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
86 buildings within 25 m of the park edge (34 mid-rise, 52 low-rise, 0 tower); avg edge height 9.0 m (~3 floors); 31.4 buildings per 100 m of 274 m perimeter — strong frontage density; edges are at a Jacobs-scale walkable mid-rise (3–7 floors); no towers immediately adjacent. "Eyes on the park" come strongest from the 34 mid-rise edge buildings.

Border Vacuum Risk
Park edges face the city — no significant border vacuum detected.

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.
- Activate the edges: encourage cafés, retail or community uses on the streets that face the park; replace blank or parking-lot edges where possible.
- 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.
