Scores are not bell-curved. Percentiles and expected scores provide context without changing the underlying model.
Explain this score
Where did the 33 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 (79) significantly outpaces natural comfort (47) — well placed in the city but offers little shade or ecological respite.
- 23 nearby towers cast wind and shadow without contributing canopy — passive surveillance is plentiful but human-scale comfort is not.
- High connectivity coexists with high border-vacuum risk (100) — much of that connectivity is to highways, rail, or parking lots, not to neighbourhoods.
Typology classification
Classified as Waterfront Park: 6% water surface inside park. Secondary read: Corridor / Linear Park (shape elongation 2.2× a circle of equal area).
Edge Activation
Within 100 m of the park edge: 8 active uses (restaurant, transit_stop) and 36 dead/hostile uses (highway, rail, 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 82 mapped paths/walkways and 104 sidewalk segments within 50 m; 22 street intersections within 100 m; 22 transit stops within a 400 m walk; 23 estimated access points across ~2,738 m of perimeter. moderate edge density — small superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
5 distinct amenity types in the park (dog_area, fitness, 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: ~11.0% effective canopy (0.7% from contiguous tree polygons + scattered tree density); 6.2% water surface; 203 city-mapped trees inside the polygon (15.8/ha). Reading: water-cooled. Source coverage: treed_area, waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
35 buildings within 25 m of the park edge (6 mid-rise, 6 low-rise, 23 tower); avg edge height 73.2 m (~24 floors); 1.3 buildings per 100 m of 2,738 m perimeter — thin frontage — significant blank-edge share; edges dominated by towers; 23 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 6 mid-rise edge buildings.

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.
- 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.
- Encourage mid-rise, windowed frontages around the park so residents have direct sightlines onto it.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
