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.
