Description: ERCA Maximum Observed Flooding
Flood levels observed due to ice jamming in Feb 1985. They were staked and serveyed by ERCA staff where the observed flood levels surpassed the 1:100 yr flood line. In some cases, these levels are above the Hurricane Hazel flood levels.
Source: Deliniation of areas with maximum observed flooding for specific events. Does not include the Harrow flood of 1989. Data created by Geordon Harvey (ERCA) ~ 2000.

Description: Ecological Land Classification (ELC) polygon layer representing vegetation communities within Canditate Natural Heritage Sites (CNHS). Merged dataset representing all surveyed areas within ERCA watershed. ELC codes provided where from original study or tranfered from LUT based on different vintage of code provided. Codes were transfered only if the translation between the two vintages (98, 08) what a 1 to 1 match.
Description: ANSIs (Areas of Natural and Scientific Interest) are polygon features that represent lands and waters containing important natural landscapes or features that are important for natural heritage, protection, appreciation, scientific study or education.Features are either provincially or regionally significant. For planning purposes, only features which are identified as provincially significant are applicable under the Provincial Policy Statement (PPS).
