Credit scorecard — Mississauga bylaw
Each category awards a maximum percentage of the annual stormwater charge as credit.
Evidence is extracted directly from the source PDF — no manual review.

Located at upstream STM Control MH for TSS removal.
SwaleBio-swales (west and east sides)
Two bio-swales on west and east sides of site, total area 398 m2. 25mm abstraction for water balance.
InfiltrationInfiltration via GreenStorm system
6.23 m3 stored in GreenStorm system to address water balance shortfall via additional infiltration.

How to read this page. Every value above was extracted from the source PDF by the
PARCELFLOW report parser, which combines a layout-robust template detector with a
validated extraction stage tuned to Ontario Functional Servicing and Stormwater
Management reports. The four-category scorecard maps the parsed evidence onto
Mississauga's credit bylaw. Numbers are estimates — engineering review still required
before submitting a formal credit application to the City.
