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.

Stormwater controls (4)
Oil-grit separatorOGS 1 (Stormceptor EFO4)
Stormceptor EFO4, drainage area 0.512 ha, 85% TSS removal efficiency, upstream flow control orifice flow rate 95 L/s, located upstream of storage tank in parking garage
Underground storageStorage Tank
Storage volume92.0 m³
Outletpipe
Located in southwest corner of site at P1 level of underground parkade; likely requires pump to discharge to 450mm concrete storm sewer on Elizabeth Street South via 300mm connection to EX. MH 1; controls 0.512 ha of site area
Green roofGreen Roof
Approximately 526 m2 of green roof incorporated on roofs of proposed building; provides flow attenuation, filtration, and evapotranspiration
Rainwater harvesting / reuseRainwater Harvesting - Irrigation and Mechanical
Rainwater collected in sump of storage tank used for irrigation of landscaped areas and planters; excess used for mechanical re-use

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.
