Abstract
This chapter examines the effectiveness of methods used to restore the infiltration capacity of permeable pavers. The decrease in infiltration capacity with age and increased traffic use was tested and the possibility of street-s\veeping/vacuuming the surface to maintain infiltration capacities of permeable pavers was investigated. Permeable pavers allow water to easily infiltrate into the subsurface layers, thus reducing the volume of runoff reaching receiving waters. As penneable-paver installations age, and are heavily used, the infiltration capacity decreases due to clogging of the extemal drainage cell (EDC) with fines (silt and day), organic matter and extractable solvents from automobiles (primmily oil and grease). An eight-year old installation of two different types of permeable pavements in a parking lot at the University of Guelph was studied. No maintenance procedmes were used over the 8 y period, other than snow removal and street sweeping with rotating brushes once a year in spring. Infiltration rates were tested before and after material was extracted from the EDCs and subjected to a particle size and constituent analysis. The extracted material was tested for a number of different organic and chemical constituents such as heavy metals, nutrients and organic matter. Results indicate that the infiltration capacity decreases with increasing average daily traffic counts, and as the amount of organic matter and fine matter in the EDC

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
