Extraction audit

Confidence: high Completeness: 100% Source: 105-page PDF Extractor: PARCELFLOW v1 Validation: passed

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.
