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



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.



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



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.
