In cooperation with local municipalities and the province, the RVCA identifies, studies and maps natural hazard areas along local rivers, lakes, streams and wetlands. Natural hazard areas include floodplains, unstable slopes. Natural features such as wetlands are also mapped. In the past, these maps were called flood risk maps.
If not understood or dealt with effectively, these hazards can pose risks and problems to society, especially when considering development activities.
Hazard mapping is used by watershed municipalities when updating Official Plan and Zoning Schedules and in the review of development applications under the Planning Act. The RVCA uses the mapping for the administration and enforcement of regulations made under the Conservation Authorities Act (Section 28).

STATION METADATA
Station Metadata [SNOW-MNR-3306]
STATUS: Active, Seasonal
ABOUT THIS DATA:
The biweekly snow depth (cm) and snow water equivalent (mm) for the Pierces Corners region (SNOW-MNR-3306). Field monitoring conducted by the RVCA. Statistics have been generated by the RVCA from the period between 1977-2019 (42 years). These statistics include the biweekly median (50th percentile), interquartile range (data range between the daily 25th and 75th percentiles) and the maximum snow water volume measured over the period of record. The median and interquartile range represent the typical normal snow water volume observed at this time of year over the historic record.
DATA TIME-SERIES:
Biweekly, Field Measurement, Snow Depth (SD); centimeters
Biweekly, Field Measurement, Snow Water Equivalent (SWE); millimeters
Biweekly, Lower Quartile (25th Percentile; Historic Normal Water Equivalent); millimeters
Biweekly, Median (50th Percentile; Historic Normal Water Equivalent); millimeters
Biweekly, Upper Quartile (75th Percentile; Historic Normal Water Equivalent); millimeters
