Data updated
Trethewey Park East scores 27 / 100. Strongest dimensions: natural comfort and enclosure / eyes on park. Weakest: edge activation (0). Border-vacuum risk is elevated (100). This score is a transparent reading of Jane Jacobs-style vitality factors, not a definitive judgment.

What's here
Getting around
856 m of mapped path, 3% paved.
No steps mapped on the path network.
No seating mapped in OpenStreetMap.
Nearest parking 3 m away. None of the 15 nearby lots records whether it has accessible spaces.
Path, seating and parking data comes from OpenStreetMap and reflects what volunteers have mapped, not a survey. Absence here means nobody has recorded it. This section does not assess wheelchair access: the relevant OpenStreetMap tag is present on well under 1% of Toronto paths.

Where did the 27 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
Trethewey Park East works because its natural comfort score (59) is above average (it sits inside the ravine system; water is part of the park).
What limits this park
Trethewey Park East is held back by edge activation (0, bottom quartile): the surrounding streets carry too few active uses to spill into the park; border-vacuum risk is also elevated (100).
Most distinctive characteristic
Most distinctive feature: exceptionally low edge activation (0, bottom quartile).
Jacobs reading
Trethewey Park East is currently underperforming on both axes: neither integrated into the city nor offering deep natural respite. A candidate for design intervention.
Performance in context
- Reads as a modest underperformer relative to comparable parks (gap -12; cohort: large Waterfront Park waterfront).
Typology classification
Classified as Waterfront Park: 12% water surface inside park. Secondary read: Ravine / Naturalized Park (100% ravine overlap, 4% canopy).
Edge Activation
Within 100 m of the park edge: 5 active uses (cafe, restaurant, retail, transit_stop) and 12 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 0 mapped paths/walkways and 19 sidewalk segments within 50 m; 6 street intersections within 100 m; 11 bus stops within a 400 m walk; 0 estimated access points across ~1,644 m of perimeter. low edge density, significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
1 distinct amenity types in the park (playground). Diversity 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: ~11.2% effective canopy (4.3% from contiguous tree polygons + scattered tree density); 100.0% inside the ravine system; 12.0% water surface; 99 city-mapped trees inside the polygon (16.0/ha). Reading: ravine-cooled. Source coverage: treed_area, ravine, waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
50 buildings within 25 m of the park edge (4 mid-rise, 46 low-rise, 0 tower); avg edge height 5.9 m (~2 floors); 3.0 buildings per 100 m of 1,644 m perimeter (strong frontage density); edges are barely there or single-storey; 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: Black Creek Drive, parking_lot, Black Creek Drive, Black Creek Drive, Black Creek Drive, Black Creek Drive, Black Creek Drive, Black Creek Drive. 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.

Does this score feel accurate?
Your read of Trethewey Park East matters. We’re testing whether the model lines up with how people actually use the park. Submissions are stored locally; no account needed.
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.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
