Explain this score
Where did the 32 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
Main Sewage Treatment Playground works because its connectivity score (72) is in the top tier and its amenity diversity (35) is also top quartile (16 transit stops sit within a 400 m walk; 14 intersections fall within 100 m of the edge).
What limits this park
Main Sewage Treatment Playground is held back by enclosure (47, bottom quartile); border-vacuum risk is also elevated (100).
Most distinctive characteristic
Most distinctive feature: exceptionally high connectivity (72, top decile).
Jacobs reading
Main Sewage Treatment Playground is currently underperforming on both axes: neither integrated into the city nor offering deep natural respite. A candidate for design intervention.
Tradeoffs
- Connectivity (72) significantly outpaces natural comfort (40): well placed in the city but offers little shade or ecological respite.
- 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 Athletic / Recreation Park: 75% of amenity types are athletic (basketball, sports_field, skatepark)
Edge Activation
Within 100 m of the park edge: 7 active uses (transit_stop, retail) and 11 dead/hostile uses (highway, 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 37 mapped paths/walkways and 45 sidewalk segments within 50 m; 14 street intersections within 100 m; 16 transit stops within a 400 m walk; 4 estimated access points across ~1,149 m of perimeter. moderate edge density, small superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
4 distinct amenity types in the park (basketball, sports_field, bench, skatepark). 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: ~3.7% effective canopy (0.7% from contiguous tree polygons + scattered tree density); nearest waterbody ~217 m; 41 city-mapped trees inside the polygon (5.3/ha). Reading: exposed. 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
13 buildings within 25 m of the park edge (4 mid-rise, 9 low-rise, 0 tower); avg edge height 8.4 m (~3 floors); 1.1 buildings per 100 m of 1,149 m perimeter (thin frontage with significant blank-edge share); edges are low-rise (mostly 2 to 3 floors); no towers immediately adjacent. "Eyes on the park" come strongest from the 4 mid-rise edge buildings.

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

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.
