Description: The Protected Areas feature class was created to help the Planners to more easily identify areas within Maple Ridge that have been protected for environmental reasons. A Dedicated Park that was meant for public use would not be included, but a Dedicated Park that was created for watercourse protection would be part of the Protected Areas feature class. The reasoning for Dedicated Parks that are included is from information provided by the Planners as well as from personnel that have knowledge of the parks in Maple Ridge. In cases where part of a Dedicated Park is for public use and another part of the Park is for environmental protection, that portion of the park was extracted to be part of the Protected Area. Covenants created for slope, geotech, vegetation retention, habitat protection etc, would be included in the Protected Area feature class, whereas covenants for septic systems would not be included. The reasoning for the covenant, if stated on the Legal Plan would be attributed as such. There will be occurrences where there is no reasoning for either but was understood that those areas were protected for environmental purposes. For this feature class, Ownership is defined as Crown, District Entire Lot, District Estimated, and Private. Crown = Parcels with no legal information, crown land District Entire Lot = Dedicated Parks that encompass an entire lot/parcel District Estimated = A portion of a Dedicated Park that is not an entire lot/parcel, the area was estimated based on orthophoto Private = Covenants created for environmental protection
Description: This dataset is used in conjuction with slope and and other environment layers for Land Use planning. The setbacks are used as a guide for development planning.

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>DHC used the 2022 4-band leaf-on orthoimagery and the December 26, 2021 leaf-off LiDAR as inputs. An object-oriented machine learning classification algorithm generated the canopy using both the imagery and 3D LiDAR data. The resulting canopy was then segmented using an individual tree detection inverse-watershed algorithm. These segments were subsequently classified into coniferous, deciduous, or dead tree classes. Manual editing was conducted by a 3 person crew based on the 2022 orthoimagery and the 2021 LiDAR nDSM (normalized Digital Surface Model) to eliminate artifacts (buildings, poles, cars, etc) from the canopy file. Lastly, tree height and crown area metrics were calculated for each canopy polygon by performing a zonal stats function on the Canopy Height Model (CHM). A height cut-off of 2m was used based on the zonal stats function. </SPAN></P></DIV></DIV></DIV>
