RE: Natural Environment Report – GRT Northfield Drive Facility Preliminary
Design and Environmental Assessment
Established in 1971
NFLD & Labrador Ontario British Columbia Alberta Yukon NWT Alaska Texas California Russia
Introduction
LGL Limited was retained by IBI Group Incorporated to investigate Natural Environment
characteristics of the GRT Northfield Drive Facility at 300 and 350 Northfield Drive East in
Waterloo, Ontario, hereinafter referred to as the site. LGL conducted an initial windshield survey
reconnaissance of the site on March 26, 2015 and on September 11, 2015 conducted a botanical
inventory, tree inventory and observations of wildlife habitat conditions. The field observations
were combined with desktop analysis of existing natural heritage and natural hazard information
to describe the natural environment characteristics of the site.
Designated Natural Heritage and Natural Hazard Features
LGL reviewed the following existing information to screen for the occurrence of designated
natural heritage and natural hazard features at the site:
• Ministry of Natural Resources and Forestry (MNRF) on-line Natural Heritage Mapping
(see Attachment 1 - MNRF Natural Heritage Areas);
• City of Waterloo Official Plan Schedule A4 – Natural System;
• City of Waterloo Official Plan Schedule A5 – Natural Hazards; and
• Grand River Conservation Authority (GRCA) Regulated Area Mapping.
There are no natural heritage or natural hazard features mapped on or immediately adjacent to the
site. The nearest natural heritage features (woodland and unevaluated wetland) are >300 meters
from the site, and are separated from the site by University Avenue to the north and Northfield
Drive, Rim Campus Lane and Labrador Drive to the south. A small tributary drainage swale

occurs on lands across Northfield from the site. The site is drained by perimeter roadside ditches
and does not appear to drain to the swale. There is no GRCA-regulated area mapped on or
immediately adjacent to the site.
LGL’s on-site observations confirmed site characteristics that were consistent with the mapping.
Plant Communities and Plant Species Inventory
LGL’s botanical inventory identified the following four plant communities according to the
Ecological Land Classification for Southern Ontario (ELC) (see Attachment 2 - ELC and Tree
Inventory):
• Manicured vegetation, including lawn and planted trees and shrubs that were being
maintained at the time of the site visit on 300 Northfield Drive East;
• Cultural Meadow, in a border around a former artificial pond at the north end of 300
Northfield Drive East;
• Willow Swamp Thicket, within the now dry former artificial pond at the north end of 300
Northfield Drive East; and
• Cultural Savannah, comprising the meadow and scattered young trees on 350 Northfield
Drive East.
Each of the latter three plant communities is the result of passive successional revegation of
previously disturbed areas on the site. None are sensitive or worthy of conservation. None
represent constraints to site development.
The plant species inventory identified a total of 86 species of trees, shrubs, vines, herbaceous
forbs and grasses (see Attachment 3 – Plant Species List). Of these, only 37 species are native to
Ontario. The 49 non-native species include trees and shrubs planted at 300 Northfield Drive East
and a host of weeds that have colonized successional plant communities at the site. No plant
Species at Risk (SAR) were observed at the site. Common Juniper is locally significant if
naturally occurring, but the Junipers on site are planted specimens and the offspring of planted
specimens and are therefore not significant.
Tree Inventory
A total of 138 trees were identified on the site (see Attachment 2 – ELC and Tree Inventory and
Attachment 4 – Tree Inventory). Of these, 2 were dead and 136 were alive. Six native and six
GRT Northfield Drive Facility February 2016 Natural Environment Report Project No. TA8581

non-native tree species occur on the site, reflecting the artificial landscape plantings on 300
Northfield Drive East and the naturally-occuring native trees, mostly Trembling Aspen, of the
Cultural Savannah on 350 Northfield Drive East. Trees on site are generally young, with no
particularly old or noteworthy specimens. No SAR or uncommon tree species occur on site.
Eighteen trees occur on or very near the eastern boundary of 300 Northfield Drive and may
require consideration of protection or compensation should they be considered owned in part or in
full by the neighbouring landowners.
Within Waterloo Region and the City of Waterloo, tree by-laws are focused on the regional
Conservation of Trees in Woodlands By-Law and the city Public Tree By-Law, neither of which
apply as the site lacks both woodland and public trees. Trees are protected within the City of
Waterloo by Official Plan Urban Forest Policy 8.2.9 which stipulates that developments must
minimize tree removal, replace removed trees in “reasonable amount” and prepare Tree
Preservation Plans to guide and accompany detailed development designs.
Tree removal (and clearing of any vegetation) must comply with the Migratory Birds Convention
Act (MBCA) that protects the nests, eggs and young of migratory birds. Compliance measures
include seasonal avoidance of bird nesting season (approximately March 25 – end of August) or
nest surveys by a qualified biologist to search for and avoid active nests.
Species at Risk Screening
Species at Risk screening included review of Natural Heritage Information Centre (NHIC)
species occurrences reported for the 1km square containing the site, complemented by site
observations of potential wildlife habitat offered by the on-site vegetation communities and the
existing building at 300 Northfield Drive East.
The NHIC database indicated Black Redhorse, a Threatened fish species that occurs in the Grand
River, and Eastern Ribbonsnake, a Special Concern snake species that is associated with wetland
habitats. Habitat for neither species occurs on or immediately adjacent to the site. In addition, the
NHIC database listed decades-old records for six plant species that are not SAR, but are
uncommon. The species were not observed at the site and are not characteristic of the existing
plant community conditions at the site.
The manicured and early successional character of the site vegetation, coupled with the close
proximity of busy roads and other human activity, contributes to an assessment of very low
likelihood of SAR plant or wildlife occurrence. Wildlife observations were limited to incidental
common songbirds and numerous Woodchuck (Groundhog) burrows around the building and
across the entire site, and signs of White-tailed Deer within the Cultural Savannah.
GRT Northfield Drive Facility February 2016 Natural Environment Report Project No. TA8581

The exterior of the existing building was inspected, but there was no sign of nesting by Barn
Swallow (Threatened). There are no chimneys on the building that are suitable for Chimney Swift
(Threatened).
It is possible that the building could support incidental summer roosting by Endangered bats such
as Little Brown Myotis, but it is not considered to be a potential overwintering site
(hibernaculum). Trees on the site are too young, smooth-barked and lacking in hollow cavities to
support bat roosting.
The Cultural Savannah on 350 Northfield Drive East is too densely treed, and too closely
bordered by busy roads to represent habitat suitable for Threatened ground-nesting birds
Bobolink and Eastern Meadowlark.
SAR concerns are therefore limited to the unconfirmed possibility of incidental bat occurrence
within the existing building. Recommended mitigation of potential impact to bats includes
avoiding the summer season for building demolition and/or building inspection prior to
demolition to confirm that no bats and bat young-of-the-year are roosting within it.
Conclusions and Recommendations
In conclusion, there are no designated natural heritage or natural hazard features at the site. The
site is characterized by manicured and early successional vegetation. Wildlife habitat is limited.
No SAR plant or wildlife species were confirmed on site and SAR occurrence is assessed as
unlikely. A possible exception could be incidental occurrence of roosting bats on or within the
existing building. Trees on site include both planted and naturally-occurring specimens of
common species. No publicly-owned trees or woodland occur on site.
As such there are no natural heritage or natural hazard constraints confirmed on the site.
However, the occurrence of trees and wildlife habitat triggers the following recommended
mitigation measures:
• Tree removal and vegetation clearing outside of the breeding bird season (approximately
25 March – end of August).
• Autumn site clearing (September – October) is recommended to reduce impacts to
mammalian wildlife by avoiding the spring/summer occurrence of young-of-the-year in
GRT Northfield Drive Facility February 2016 Natural Environment Report Project No. TA8581
LGL Limited environmental research associates Page 5
burrows, dens and the Cultural Savannah, and by avoiding the winter denning/hibernation
period.
• Demolition of the existing building is recommended to occur outside of the summer bat
maternal roosting period, or to be subject to inspections to confirm absence of roosting
bats and their young.
Site preparation and grading impacts may result in erosion of exposed soils. Sedimentation and
erosion controls should be implemented to control site runoff and prevent the transport of eroded
materials to local watercourses.
Mitigation of tree loss may require compensatory tree planting to be incorporated into detailed
design of the development, and protection of retained trees to be specified in a Tree Preservation
Plan.
