An urbanistic approach to aggregate quarrying: a case study in Brampton, Ontario
Bibliographic record
Abstract
The reclamation of urban aggregate quarries has been recognised as a serious concern for built environment design and planning fields. However, much of the literature and research centred on this challenge tends to focus on the immediate techno-scientific reclamation practices employed at a site scale often towards the end of extraction. This essay argues for a reversal of this relationship between the designer/planner and the extraction-reclamation timeline. It does so by articulating an approach based upon ‘scenario planning’ that places reclamation planning and design at the beginning of the quarry timeline rather than at the end. Further, an example of this approach in Brampton, Ontario, is analysed to determine the strengths and weaknesses of urbanistic reclamation strategies. If we pivot towards designing reclaimed landscapes from the outset, we can use such sites as the beginning point for structuring cities, rather than leaving them as holes in the urban fabric.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
