Re: Addendum to Environmental Impact Study, Proposed Watermain for 70
Pioneer Trail, City of Barrie
Dear Ms. Clement:
Azimuth Environmental Consulting, Inc. (Azimuth) was retained to assess potential
impacts to environmental features associated with a proposed watermain for a 43-unit
residential development at 70 Pioneer Trail in the City of Barrie (Figure 1). This letter is
intended to function as an addendum to the Environmental Impact Study (EIS) prepared
by Azimuth (June 2017) for the above-described property. The lands described in this
letter report do not belong to the developable area described in Azimuth’s EIS for 70
Pioneer Trail.
This letter report was initially dated August 30, 2017, and has been updated to address
comments received from the Lake Simcoe Region Conservation Authority (LSRCA) in
correspondence dated November 13, 2017. An updated plan and profile of the proposed
watermain corridor is presented in Attachment 1, and the above-described LSRCA letter
is presented in Attachment 2. Pursuant to the letter received from LSRCA, The Jones
Consulting Group Ltd. offers the following to address comments A, B and F (remaining
comments C, D, E, and G are addressed elsewhere in this updated letter report):
Comment A: The previously provided Plan and Profile Drawing No. PP-1 and PP-2 have
been updated to show the limit of trench disturbance (Attachment 1). In addition,
Drawing No. SEC-1 has been attached and includes detailed section views of the
proposed watermain (Attachment 1). It is currently anticipated that directional drilling
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 2
will only be required within 25 m of the existing Butternut tree to be protected. However,
it is important to recognize that directional drilling could be used to install the entire
length of watermain from Loyalist Court to Pioneer Trail. Due to the narrow width
associated with the existing walkway/trail, we acknowledge that the open cut installation
method would be challenging, but may still be a cost effective alternative. The open cut
installation method would require the use of trench boxes, and there would be no room to
stockpile excavated material. All excavated material would be required to be loaded on
trucks and removed to allow trenching operations and then trucked back to reinstate the
trench. The final limits of directional drilling and open cut installation methods will be
determined during the detailed design stage of the project once additional landscape and
geotechnical studies are completed. Any dewatering requirements and/or strategies
would also be identified at the detailed design stage.
Comment B: As previously noted, the current specified length of directional drill is based
on providing a minimum disturbance free zone of 25 m surrounding the existing
Butternut tree to be protected. The directional drill may be extended to include the entire
length of the walkway/trail between Loyalist Court and Pioneer Trail, should additional
protection of existing vegetation be required. We note LSRCA‟s preference to extend the
directional drill at the north end of the study area and will incorporate this
recommendation into the detailed design at which time the final extents of directional
drilling will be determined. It is important to recognize that a 4 m wide by 12 m long
sending/receiving pit will be required at either end of the directional drill to facilitate
installation.
Comment F: The proposed watermain between Loyalist Court and Pioneer Trail will be
located on lands owned by the City of Barrie. As the proposed watermain will also be
municipally owned and operated, we do not anticipate any easements or access
agreements will be required for maintenance purposes. Furthermore, we are not aware of
any current City improvement plans for the existing trail.
Executive Summary
The proposed watermain installation is consistent with the policies of the
Provincial Policy Statement, Endangered Species Act, 2007 (ESA), Lake Simcoe
Protection Plan, City of Barrie Official Plan, and Lake Simcoe Region
Conservation Authority O. Reg. 179/06.
All works will be limited to the earthen pathway connecting Loyalist Court with
Pioneer Trail. No vegetation clearance beyond the pathway corridor limit will
occur as a result of the proposed watermain installation.
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 3
One (1) Category 2/3 (“retainable”/“archivable”) Butternut tree (Endangered
under the ESA) was identified within 25 metres (m) of the pathway edge.
Directional drilling techniques will be undertaken within 25 m of this tree to
avoid negative impacts to its critical root zone, and as such there is no expectation
the proposed works will result in a contravention of the ESA. This technique has
been reviewed and approved by the Ministry of Natural Resources and Forestry
(MNRF) for the proposed installation.
Adjacent lands contain Significant Woodland. Adjacent lands also contain
potential Bat Maternity Colony Habitat, potential Habitat for Rare and Special
Concern Species, potential Habitat for Endangered and Threatened Species, and
wetland that may be considered locally Significant Wetland. If the above
confirmed and potential Significant Natural Heritage Features (SNHF) and
Significant Wildlife Habitat (SWH) features are assumed to be present, none are
expected to be negatively impacted by the proposed watermain installation,
providing mitigation measures described below (Section 8) are followed.
1.0 INTRODUCTION
The purpose of this addendum is to provide a site assessment for lands within and
adjacent to the proposed watermain corridor (Figure 1; Attachment 1) including a
screening for SNHF, SWH, and potential habitat for Species at Risk (SAR) listed under
the ESA. This addendum provides an impact assessment based on the proposed
watermain corridor, and provides recommendations for avoidance of impacts where
potential environmental impacts have been identified. This addendum was prepared at
the request of the client as portions of the proposed watermain corridor are regulated by
LSRCA under Ontario Regulation 179/06 and as such a permit will be required from
LSRCA prior to any work being undertaken. It is our understanding that The City of
Barrie requested that the watermain installation take place, and are supportive of the
works described in this letter report.
A site plan for the proposed watermain corridor is presented in Attachment 1, the limits
of which are restricted to an established earthen footpath between Loyalist Court and the
Pioneer Trail. For the purposes of this study, the term “watermain corridor” refers to the
earthen pathway (i.e. proposed watermain footprint), and the term “adjacent lands” refers
to all lands within approximately 50 m of the pathway edge. The term “study area” refers
to all surveyed lands including the watermain corridor and adjacent lands.

2.0 BACKGROUND INFORMATION
A review of the following background documents provided information on site
characteristics, habitat, wildlife, rare species and communities and general
cultural/historic aspects of the watermain corridor and adjacent lands:
MNRF‟s Natural Heritage Information Center (NHIC)
Atlas of the Breeding Birds of Ontario (OBBA)
Ontario Reptile and Amphibian Atlas
MNRF's Species at Risk Ontario list;
Air photos available for the Project Area (Google, VuMap)
Government of Canada's Species at Risk Public Registry;
Atlas of the Mammals of Ontario (Dobbyn, 1994).
3.0 SCREENING APPROACH
Azimuth staff attended the study area on June 20, 2017 to carry out an assessment of the
proposed watermain corridor and adjacent lands (lands within approximately 50 metres
of the proposed watermain corridor). Prior to undertaking the field study, an initial
classification of habitats was undertaken using recent air photo imagery for an area
encompassing the watermain corridor and adjacent lands. Vegetation boundaries were
then checked in the field and confirmed as depicted in Figure 1. Vegetation community
types were classified using the Ecological Land Classification for Southern Ontario: First
Approximation (ELC: Lee et al., 1998).
The SNHF, SAR and SWH screenings undertaken for the scope of this assignment
compared the habitat requirements of species with potential to occur in the overall
planning area with habitat types that occur on the property. The screening is based on air
photo interpretation combined with onsite evaluation of the habitat as described above.
4.0 SUMMARY OF EXISTING CONDITIONS
4.1 Land Use
The proposed watermain corridor consists of an established earthen pathway
approximately 4 m in width running north-south through an extensive woodland feature,
directly connecting Loyalist Court with Pioneer Trail.
Adjacent lands consist of dense coniferous, mixed, and deciduous fresh-moist woodland,
and dense coniferous swamp demonstrating evidence of groundwater influence beyond
the established trail limits (Figure 1).
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 5
A residential development is located beyond the southern terminus of the trail (at Loyalist
Court) and residential shoreline properties are located beyond the northern terminus of
the trail (at Pioneer Trail). The Lake Simcoe shoreline is located approximately 130 m
beyond the northern limit of the trail.
The property and surrounding lands are located within the City of Barrie and are
designated “Environmental Protection Area” within the City of Barrie‟s Land Use Plan
(Schedule A; City of Barrie, 2014). Further, the City of Barrie‟s Natural Heritage
Resources Schedule (Schedule H; City of Barrie, 2014) identifies the study area as a
“Level 1” Natural Heritage Resource (Environmental Protection Area). According to
Section 5.1.2.1(a) of the City of Barrie Official Plan (City OP; 2014):
“Public Utilities, including... municipal water... shall be permitted within any land use
designation of this Plan... Where the location of public utilities on lands designated
Environmental Protection or Open Space is efficient, cost effective and in the public
interest, an EIS shall be undertaken...”
4.2 Vegetation
A field survey was undertaken to confirm vegetation community types and plant species
compositions within the proposed watermain corridor (trail limits) and of adjacent
woodlands/wetlands on June 20, 2017, including detailed in-field delineation of wetland
communities adjacent to the watermain corridor. The site visit was undertaken by a
qualified Terrestrial Ecologist with existing knowledge related to rare, Threatened, and
Endangered plant species with potential to occur in the area.
Lands within the proposed watermain corridor limits consisted of a compacted earthen
footpath with minimal vegetation cover. Vascular plant species within and along the
fringes of the footpath limits were primarily limited to those characteristic of disturbed
areas (several of which are non-native and/or aggressive in nature), including Canada
Goldenrod (Solidago canadensis), Crown Vetch (Securigera varia), Kentucky Bluegrass
(Poa pratensis ssp. pratensis), Coltsfoot (Tussilago farfara), Common Dandelion
(Taraxacum officinale), and Common Plantain (Plantago major) in descending order of
dominance. Except at the northern end in the vicinity of the SWC1 feature, mature trees
on adjacent lands form a closed canopy over the pathway, further detailed in Table 1
below.
Lands adjacent to the earthen watermain corridor consist of maintained lands, coniferous
forest, deciduous forest, and coniferous swamp vegetation communities (as defined by
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 6
the ELC system), summarized in Table 1 below. Vegetation communities on adjacent
lands are illustrated in Figure 1.
Table 1: Vegetation Communities Adjacent to Study Area
Unit Description
FO (FOREST) Tree cover >60%. Site conditions and substrate types variable
FOC (Coniferous Forest) Conifer tree species >75% of canopy cover.
FOC1 (Dry-fresh Pine
Coniferous Forest)
This community is composed of dense (>60%) canopy and subcanopy cover in
and is dominated by Red Pine (Pinus resinosa) with Balsam Poplar (Populus
balsiamifera), White Birch (Betula papyrifera), and Eastern White Cedar (Thuja
occidentalis) associates.
FOC4 (Fresh-moist White
Cedar Coniferous Forest)
This community is composed of dense (>60%) canopy and subcanopy cover and
is dominated by Eastern White Cedar with Green Ash (Fraxinus pennsylvanica),
White Birch, and Black Walnut (Juglans nigra) associates.
FOD (Deciduous Forest) Deciduous tree species >75% of canopy cover.
FOD5 (Dry-fresh Sugar
Maple Deciduous Forest)
This community is composed of dense (>60%) canopy and subcanopy cover in
with Sugar Maple (Acer ssccharum), Green Ash, White Birch, Black Cherry
(Prunus serotina), and Black Walnut( in descending order of density.
SW (SWAMP) Tree or shrub cover >25%. Dominated by hydrophytic shrub and tree species.
SWC (Coniferous
Swamp)
Tree cover >25% trees; trees >5 m in height. Conifer tree species >75% of
canopy cover.
SWC1 (White Cedar
Mineral Coniferous
Swamp)
This community is composed of dense (>60%) canopy and subcanopy cover and
is dominated by Eastern White Cedar, with Green Ash, Balsam Poplar, and
Black Cherry associates.
4.3 Aquatic Habitat and Fisheries
No intermittent or permanent water bodies, intermittent or permanent watercourses were
identified within the study area or adjacent lands, and as such there is no potential for fish
or fish habitat.
A limited amount of standing water may occur in the early spring months within the
SWC1 feature in adjacent lands beyond the eastern and western limits of the watermain
corridor (Figure 1; Table 1), however no standing water was present in proximity to the
trail during the June 20, 2017 site investigation. Further, based on a review of the greater
landscape it is expected that any such pooling would be limited and isolated from any
permanent or intermittent watercourses/waterbodies with the potential to provide fish
habitat.
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 7
5.0 NATURAL HERITAGE FEATURES AND FUNCTIONS
Based on a review of background data and the detailed assessment for the proposed
residential development at 70 Pioneer Trail (Azimuth, 2017), all SNHFs including SWH,
and SAR that have the potential to occur in the area were considered in our EIS on the
adjacent property, and are considered for the watermain corridor and adjacent lands as
follows:
5.1 Significant Natural Heritage Features
The City OP describes woodlands within Environmental Protection lands >10 hectares as
Significant Woodland. As such, vegetation community units FOC2-2, FOM4, FOD5,
and SWC1 within the study area limits should be considered as belonging to the
Significant Woodland.
Wetlands (SWC1; Figure 1) are located on adjacent lands, and as such Non-Provincially
Significant Wetlands >0.5 hectares may also be considered locally Significant Wetlands
in accordance with City OP direction.
No valleylands according to definitions presented in the City OP or Natural Heritage
Reference Manual (NHRM; OMNR, 2010) are located within the watermain corridor or
adjacent lands.
5.2 Significant Wildlife Habitat
Candidate Significant Wildlife Habitat as defined by the Significant Wildlife Habitat
Technical Guide (SWHTG; OMNR, 2000) and Significant Wildlife Habitat Criteria
Schedules for Ecoregion 6E (MNRF, 2015) was also evaluated as a part of this
assessment.
5.2.1 Candidate Significant Bat Maternity Colony Habitat
According to the SWHTG Ecoregion 6E Criteria Schedules (MNRF, 2015), Bat
Maternity Colony Habitat can be found in tree cavities, preferably located in mature
mixed and deciduous forest stands >10 hectares in size, preferably in large snag trees
(>25cm diameter at breast height) in the early stages of decay. Mature forested and
swamp vegetation communities (FOC1, FOC4, FOD5, SWC1; Figure 1) on adjacent
lands may provide Candidate Significant Bat Maternity Colony Habitat.
5.2.2 Candidate Amphibian Breeding Habitat (Woodland)
According to the Ecoregion 6E Criteria Schedules (MNRF, 2015), the presence of a
wetland, pond, or woodland pool (including vernal pools) >500m2 within or adjacent to a
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 8
woodland, containing water until mid-July is the preferred woodland breeding habitat for
amphibians. No pooled water is present at any time of year within the limits of the
proposed watermain corridor. On adjacent lands, herbaceous wetland vegetation was
identified within the SWC1 features on June 20, 2017 (indicating a high water table),
however no pooled water was present at the time of the investigation such that amphibian
breeding habitat would be supported adjacent to the watermain corridor limits. The
proposed watermain corridor and adjacent lands do not qualify as Candidate Amphibian
Breeding Habitat (Woodland).
5.2.3 Candidate Habitat for Rare and Special Concern Species
According to the SWHTG Ecoregion 6E Criteria Schedules (MNRF, 2015), SWH for
rare and Special Concern species is characterized by the presence of any species
considered provincially rare (ranked S1-S3) or designated Special Concern under the
ESA, and as such the area may provide Candidate Habitat for Rare and Special Concern
Species.
Given our understanding of the habitat requirements of the above noted species as per
Provincial Recovery Strategies, species specific habitat regulations under the ESA, 2007
(Ontario Regulation [O. Reg.] 242/08), and the screening presented in the EIS for 70
Pioneer Trail (Azimuth, 2017), the following Special Concern species have the potential
to be located within the watermain corridor and adjacent lands:
Eastern Wood-pewee (Contopus virens; Special Concern) – identified during
2015 EIS surveys
Wood Thrush (Hylocichla mustelina; Special Concern) – identified during 2015
EIS surveys.
5.3 Habitat for Endangered and Threatened Species
Based on the assessment of the study area undertaken, no faunal SAR have been
confirmed within the property or adjacent lands. Given our understanding of the habitat
requirements of the above noted species as per Provincial Recovery Strategies, species
specific habitat regulations under the ESA, 2007 (O. Reg. 242/08), and the screening
presented in the Environmental Impact Study for 70 Pioneer Trail (Azimuth, 2017), the
following faunal Endangered and species have the potential to be located within the
vicinity of the study area:
Little Brown Myotis (Endangered)
Northern Myotis (Endangered)
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 9
Tri-colored Bat (Endangered)
Four (4) Butternut (Endangered) trees were encountered on adjacent forested lands within
the critical habitat zone (25m buffer) of the watermain corridor, illustrated in Figure 1.
This species occurs on a variety of sites, including dry rockier soils (particularly those of
limestone origin), growing best on well-drained fertile soils in shallow valleys and on
gradual slopes; singly or in small groups mixed with other species. This species is
intolerant of shade (Farrar, 1995).
6.0 PROPOSED WORKS
The proposed residential development will be serviced from existing municipal water
infrastructure located within the Pioneer Trail Right of Way. In order to improve
redundancy and pressures of the existing municipal water system, it was determined
through pre-consultation with the City of Barrie that a 200 mm diameter PVC watermain
loop, between existing municipal infrastructure on Loyalist Court and Pioneer Trail,
would be required. As outlined above, the proposed watermain will be located within the
existing earthen pathway that leads from the Loyalist Court cul-de-sac, north to Pioneer
Trail. The proposed watermain loop will span between the City of Barrie pressure Zone
1 and 2 South, as such, a Pressure Reducing Valve (PRV) will need to be installed. It is
anticipated that this PRV will be located adjacent to the Loyalist Court cul-de-sac.
Two construction methods are proposed to install the watermain approximately 2 to 3 m
below existing grade of the foot path. Micro-tunnelling/directional drilling may be used
where necessary, to limit potential disturbance of existing vegetation. Utilizing micro-
tunnelling/directional drilling would result in no above grade impacts to the watermain
corridor, with the exception of two (2) 4 m wide x 12 m long open cut sending/receiving
pits located at either end of the directional drill. Open cut trenching may also be utilized
for installation of the watermain, where above grade disturbance is deemed acceptable.
The below grade disturbance of the open cut installation method can be limited to
approximately 2 m through the use of a trench box; however, the work area/limit of
disturbance above the trench would be approximately 4 m to facilitate appropriate heavy
equipment for installation.
7.0 IMPACT ASSESSMENT
7.1 Significant Natural Heritage Features
Wooded vegetation communities on adjacent lands (FOC1, FOC4, FOC5, SWC1; Figure
1) are considered to be Significant Woodland, however no woody vegetation within these
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 10
communities will be subject to removal as a result of the proposed works. Wetland
vegetation on adjacent lands will not be subject to any direct disturbance.
Direct disturbance to the earthen trail along the proposed watermain corridor will be
limited and temporary in nature, with post-installation vegetation conditions expected to
be very similar or identical in appearance to pre-disturbance conditions. Vegetation
removals will be limited to species characteristic of disturbed areas (several of which are
non-native and/or aggressive in nature) detailed in Section 4.2 above.
With these considerations, it expected that there will be no negative impact to Significant
Woodland or potential Non-Provincially Significant Wetland as a result of the proposed
works, provided that conformance is demonstrated for environmental considerations and
mitigation described below (Section 8).
7.2 Candidate Significant Wildlife Habitat
No woody vegetation removals will occur as a result of the proposed watermain
installation (including large snags and/or mature trees in the early stages of decay), and
thus no direct disturbance to potential Candidate Bat Maternity Colony Habitat is
expected. Provided that conformance is demonstrated for environmental considerations
and mitigation described below (Section 8), no direct or indirect negative impacts to this
candidate SWH type are expected as a result of the watermain installation.
During the course of the field program for the EIS at 70 Pioneer Trail (Azimuth, 2017),
presence of Eastern Wood-pewee (Special Concern) and Wood Thrush (Special Concern)
was confirmed. These species should be assumed to be present elsewhere within the
contiguous woodland feature (i.e. the watermain corridor), and therefore the forested
lands adjacent to the watermain corridor are considered to provide Candidate Habitat for
Rare and Special Concern Species.
The Eastern Wood-pewee lives in the mid-canopy layer of forest clearings and edges of
deciduous and mixed forests (MNRF, 2015), and the Wood Thrush lives in mature
deciduous and mixed (conifer-deciduous) forests (MNRF, 2015). No woody vegetation
removals will occur as a result of the proposed watermain installation, and thus no direct
disturbance to candidate SWH is expected. Provided that conformance is demonstrated
for environmental considerations and mitigation described below (Section 8), no direct or
indirect negative impacts to this candidate SWH type are expected as a result of the
watermain installation.
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 11
7.3 Habitat for Threatened and Endangered Species
Impacts with regards to the ESA and Habitat of Threatened or Endangered Species are
covered under Section 9 and 10 of the ESA. Section 9 deals directly with killing,
harming, or harassing living members of a species while Section 10 covers destruction or
damage to habitat of Threatened or Endangered species. The following Threatened and
Endangered species have the potential to occur within adjacent lands:
Little Brown Myotis (Endangered)
Northern Myotis (Endangered)
Tri-colored Bat (Endangered)
As discussed above, no woody vegetation removals will occur as a result of the proposed
watermain installation (including large snags and/or mature trees in the early stages of
decay), and thus no direct disturbance to potential bat habitats is expected. Provided that
conformance is demonstrated for environmental considerations and mitigation described
below (Section 8), no direct or indirect negative impacts to these species are expected as
a result of the watermain installation.
The following Endangered floral species was confirmed on lands adjacent to the
watermain corridor within its 25 m critical habitat buffer:
Butternut (Endangered)
Upon identification correspondence took place with MNRF to discuss an acceptable
strategy for proceeding with the proposed watermain installation without killing or
harming individual Butternut trees or disturbing critical habitat buffer zones to avoid
contravention of Section 9 and 10 of the ESA. It was agreed during this correspondence
that microtunnelling/directional drilling of the watermain within 25m of Category 2 or
Category 3 (“retainable” or “archivable”) trees was an acceptable strategy for avoiding
contravention of the ESA, pending a Butternut Health Assessment. Category 1 (“non-
retainable”) Butternut trees are not afforded protection under the ESA and therefore there
is no requirement for microtunnelling/directional drilling within 25m of these trees.
Attachment 3 contains a correspondence record with MNRF confirming the above
rationale as an acceptable evaluation strategy.
A Butternut Health Assessment was conducted by Daniel Stuart (certified Butternut
Health Assessor #609) for all four trees on June 20, 2017, at which time three (3)
Butternut trees were evaluated to be Category 1 (“non-retainable”) or dead. One (1)
Butternut tree (depicted in Figure 1) was evaluated to be Category 3 (“archivable”) and
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 12
therefore is protected under the ESA. Following this assessment, correspondence took
place with MNRF (see Attachment 3) to confirm that should microtunneling/directional
drilling take place for the section of the watermain corridor within 25 m of the Category 3
tree (Figure 1), there is no expectation that a contravention of the ESA would occur as a
result of the proposed works. The site plan (Attachment 1) was revised to reflect this
agreement, and as a result there will be no negative impact to Butternut trees protected
under the ESA or their critical habitat buffer zones as a result of the proposed works.
8.0 RECOMMENDATIONS
8.1 Species at Risk
It should be noted that the absence of a protected species within the property does not
indicate that they will never occur within the area. Given the dynamic character of the
natural environment, there is a constant variation in habitat use. Care should be taken in
the interpretation of presence of species of concern including those listed under the ESA.
Changes to policy, or the natural environment, could result in shifts, removal, or addition
of new areas to the list of areas currently considered candidate Significant Natural
Heritage Features. This report is intended as a point in time assessment of the potential
to impact SAR; not to provide long term „clearance‟ for SAR. While there is no
expectation that the assessment should change significantly, it is the responsibility of the
proponent to ensure that they are not in contravention of the ESA at the time that site
works are undertaken. A review of the assessment provided in this report by a qualified
person should be sufficient to provide appropriate advice at the time of the onset of future
site works.
8.2 Worker Training
Worker training would assist the on-site workers in the identification of the SAR with
potential to occur in the area. Workers should be instructed to stop work immediately
and contact the local MNRF office immediately if any SAR are encountered within the
work area. Individuals working on site should ensure that SAR are not harmed during
construction or killed by heavy machinery, vehicles or other equipment.
The contractor should seek to ensure that all personnel are educated to ensure that, if
identified, the SAR are not wantonly injured or killed, and to ensure that damage to
features which could constitute habitat is avoided. Information conveyed through this
education should include:
Species habitat and identification;
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 13
Requirements under the ESA including avoidance of harm to the species and
damage to relevant habitat;
Appropriate action to take if the species is encountered;
How to record sightings and encounters; and
That care should be taken when undertaking construction activities in order to
avoid harming the species or damaging/destroying habitat.
The expert should be a qualified biologist who specializes in ecology/biology, or SAR.
8.3 Migratory Breeding Birds
Activities involving the removal of vegetation should be restricted from occurring during
the breeding season. Migratory birds, nests, and eggs are protected by the Migratory
Birds Convention Act, 1994 and the Fish and Wildlife Conservation Act, 1997.
Environment Canada outlines dates when activities in any region have potential to impact
nests at the Environment Canada Website (http://www.ec.gc.ca/paom-
itmb/default.asp?lang=En&n=4F39A78F-1#_03). In Zones C1 and C2 vegetation
clearing should be avoided between April 1st through August 31st of any given year. If
work requires that vegetation clearing is required between these dates screening by an
ecologist with knowledge of bird species present in the area could be undertaken within
48 hours of initial vegetation clearance within a given area to ensure that the vegetation
has been confirmed to be free of nests prior to clearing. Should vegetation clearance
activities pause within the given area for more than 48 hours, an additional screening by
an ecologist should occur to ensure new nest establishment has not occurred.
8.4 Operations
Diligent application of sediment and erosion controls should be installed prior to all
construction activities along the watermain corridor limits, with particular emphasis
portions of the work area adjacent to wetland units (SWC1; Figure 1) to alleviate the risk
of sediment entering adjacent wetlands during construction. A double sediment control
fence with hay bales between should be installed at the limit of the work area to prevent
the accidental intrusion of machinery operations into adjacent undisturbed natural areas.
All maintenance activities required during future construction should be conducted 30m
away from confirmed or potential wetland or groundwater discharge features to prevent
accidental spillage of deleterious substances that may harm natural environments.
Snow fencing or equivalent should be installed at the limit of the work area to prevent the
accidental intrusion of machinery operations into adjacent undisturbed natural areas.
AZIMUTH ENVIRONMENTAL CONSULTING, INC. 14
8.5 Vegetation Mitigation and Compensation
An appropriate vegetation mitigation and compensation strategy should be undertaken to
the degree necessary to mitigate impacts to vegetation associated with the watermain
installation, as follows:
A Tree Inventory and Preservation Plan should be prepared at the Site Plan
control stage to assess potential impacts to nearby trees (e.g. impacts to root zone)
and provide management recommendations.
Although works will be limited to the limits of the earthen pathway (i.e. trail), a
restoration plan should prepared and implemented should any vegetated area be
inadvertently disturbed beyond the pathway limits during project works.
9.0 CONCLUSIONS
Based upon our analysis, it is concluded that the environmental conditions within the
study area are not limiting to the implementation of proposed development to proceed
through incorporation of the environmental protection measures and criteria as described
throughout this EIS addendum. This addendum letter relies on information collected for
and presented in the EIS prepared for 70 Pioneer Trail (Azimuth, 2017), and as such it
should be read in conjunction with that report and the supporting documentation.
Our findings are summarized as follows:
1. The proposed watermain installation is consistent with the policies of the
Provincial Policy Statement, ESA, Lake Simcoe Protection Plan, City of Barrie
Official Plan, and Lake Simcoe Region Conservation Authority O. Reg. 179/06.
Natural Heritage Resources identified by the City of Barrie will not be negatively
affected by the proposed watermain installation.
2. Our impact assessment has given full consideration to the habitat requirements of
all SAR assumed and documented to occur in the area and results indicate the
proposed development will not result in negative direct or indirect impacts to
habitat of SAR providing conformance is demonstrated to mitigation measures
described in Section 8.
3. The proposed development will not negatively impact the ecological functions of
SNHF or candidate SWH outlined in Section 5 if the appropriate mitigation
measures described in Section 8 are followed.

Ms. Kathy Brislin Senior Planner Planning Services City of Barrie 70 Collier Street, Box 400 Barrie, ON L4M 4T5 Dear Ms. Brislin: Re: Official Plan Amendment and Zoning By-law Amendment 70 Pioneer Trail City of Barrie Further to our letter of February 15, 2017, we have completed our review of the latest technical submission and provide the following comments. NATURAL HERITAGE The following natural heritage comments are numbered in accordance with LSRCA correspondence dated January 16, 2017. Comment 1. Addressed. Comment 2. Addressed. Comment 3. Addressed. Comment 4. This comment requested that a feature-based water balance be prepared for the property. The
EIS has been updated to provide additional detail and assessment and has determined that the woodland feature would not be significantly impacted from a hydrological perspective. Comments with respect to the water balance review will be provided under separate cover.
Comment 5. Addressed. Comment 6. Addressed. Comment 7. Addressed. New Comment – the proposed watermain was not contemplated in the EIS. All mitigation measures as identified in Section 8.0 of the EIS should be implemented. In particular, the following Plans and Strategies should be required at detailed design:
1. Erosion and Sediment Control Plan 2. Boundary Tree Inventory and Protection Plan
Page 2 of 3
3. Edge Management Plan 4. Buffer (Vegetation Protection Zone) Restoration/Enhancement Plan 5. Ecological Offsetting Strategy
The LSRCA has also reviewed the “Addendum to the EIS, Proposed Watermain for 70 Pioneer Trail”, prepared by Azimuth Environmental Consulting (August 30, 2017). Please note: this Addendum is specific to the watermain installation proposed through the property to the south-west of 70 Pioneer Trail. Based on our review of the Addendum document, we provide the following comments: Comment A Additional information regarding the staging and installation of the proposed watermain is
required and must include:
drawings that show the area of disturbance, including the areas where excavated materials will be placed
dewatering strategy for areas where trenching is proposed
full set of engineering drawings showing cross sections
Comment B It is LSRCA’s preference that directional boring be used to install the watermain near the
wetland at the north end of the study area as well to minimize disturbance to soil and vegetation.
Comment C To avoid any contravention of the Migratory Birds Convention Act, work should be completed
outside of the general nesting window of April 1 – August 31. If work must be completed inside this window, a search for any evidence of nesting on the ground or in the area of disturbance should be completed by a qualified ecologist within 48 hours prior to any work commencing. If nesting is confirmed, appropriate buffers should be established.
Comment D A Tree Inventory and Preservation Plan will be required to assess potential impacts to nearby trees (e.g. impacts to root zone) and provide management recommendations.
Comment E A restoration plan will be required for any disturbed areas.
Comment F Please provide details regarding any future access planned to allow for maintenance of this
watermain or to maintain a trail.
Comment G Please note that the area where the watermain is proposed is partially governed by Ontario
Regulation 179/06 under the Conservation Authorities Act and a permit will be required from LSRCA prior to any work being undertaken.

Hi Brent,
Thanks for the confirmation.
Directional drilling will be to a depth of 2.0-3.5 metres below the existing ground level. All work will occur within the
limits of the existing earthen footpath. Where open cut work is planned (outside of the 25 metre buffer from Butternut
#2), a trench box will be used to stay within the limits of the pathway. As such, no tree removal will result from the
watermain installation.
Let me know if you have any additional questions or concerns.
Regards,
Dan Stuart

Hi Dan,
2
Your proposed mitigation will avoid any contravention of the Endangered Species Act (ESA). Thanks for encouraging
your client to avoid impacting the Butternut through the use of microtunnelling / directional drilling.
How deep is the directional drilling and is there any tree removal involved in the proposed works?

Subject: Butternut Health Assessment Report - Pioneer Trail Watermain Looping, City of Barrie
Good afternoon Brent,
Please see the attached Butternut Health Assessment Report for trees adjacent to the proposed watermain installation
between Pioneer Trail and Loyalist Court in the City of Barrie. An updated figure of surrounding natural features, and
current site plan are also attached for your reference.
As previously discussed, our client has been exploring options for microtunnelling/directional drilling as a means of
avoiding impacts to Category 2 and/or Category 3 Butternut adjacent to the work area, an existing earthen pathway.
As per the attached Butternut Health Assessment, the tree of most concern due to the need for open pit work within 25
metres of the tree (Butternut #4), has since died and partially fallen over (i.e. Category 1/non-retainable). Of the four
trees assessed, three were evaluated to be Category 1, and one tree adjacent to the pathway was evaluated to be
Category 3.
Pending your review of the attached, please confirm that it is appropriate for our client to adjust the attached site plan
to conduct microtunnelling/directional drilling within 25 metres of Butternut #2 only, and open pit/open cut work
elsewhere, as there is no expectation that directional drilling/microtunnelling within 25 metres of the Category 3 tree
(Butternut #2) will result in a contravention of the ESA.
Should you have any comments or questions, please don't hesitate to give me a call.
Regards,
Dan Stuart

From: Dan StuartSent: April-11-17 11:48 AMTo: 'Findlay, Graham (MNRF)'; 'Robinson, Suzanne (MNRF)'Cc: 'Shirley, Brent (MNRF)'Subject: 70 Pioneer Trail, City of Barrie - Butternut Adjacent to Proposed Watermain LoopingAttachments: Watermain Looping - 70 Pioneer - FER-15101-BASE-REV-4 PP-1 (1).pdf; Watermain
Looping - 70 Pioneer - FER-15101-BASE-REV-4 PP-2 (1).pdf; 70 Pioneer - Natural Features -Watermain Looping.pdf
Good morning Graham & Suzanne,
Azimuth was in communication with MNRF in 2015 about Species at Risk for a property located at 70 Pioneer Trail in the
City of Barrie. Since that time our client has reached an agreement with the City of Barrie to also install a watermain
looping between Pioneer Trail and Loyalist Court just west of the proposed development area. The watermain route
was chosen to be installed along an existing earthen footpath that travels through an area of deciduous and coniferous
forest (Environmental Protection lands as per City of Barrie Official Plan). Vegetation removal associated with this
installation would consist of a minimal amount of cultural/anthropogenic grasses and forbs along the earthen path’s
fringes, and would not involve the removal of herbaceous ground forbs characteristic of forest communities, or any
woody stems. The attached figure and preliminary design provide a concept of the proposed watermain in the context
of surrounding natural heritage features.
Azimuth conducted a screening of the proposed watermain route during winter 2017 and noted that four (4) Butternut
(3 mature, 1 sapling) were located within 50 metres of the pathway (see figure).
Our client has indicated that they wish to accomplish the watermain looping without subjecting any of the four
Butternut stems to “harm” as per the ESA definition, and thus avoid an ESA Registration and compensation if possible.
Based on Azimuth’s previous experience with watermain projects, we understand that this can be accomplished with a
microtunnelling/directional drilling technique within the critical habitat zone for Butternut trees (we are assuming 50
metres from each stem). Our client has proposed using an open cut technique with appropriate mitigation along the
pathway outside of the 50 metre buffer, and using microtunnelling/directional drilling within the 50 metre buffer.
Engineering constrains, however would require a small open cut trench to be created within the 50 metre buffer to tie
in the northern end of watermain looping with the existing watermain on Pioneer Trail (see attached design drawing).
Note that post-installation conditions will return the land use to a public pathway and intend to match existing site
conditions along the path.
We are asking that MNRF please comment and/or confirm that the above strategy could be put into place and not be
considered “harm” to the four Butternut stems identified adjacent to the earthen pathway (see attached figure). I am
happy to discuss this further with you over the phone, or through an office and/or site meeting. We are seeking written
confirmation/recommendations from MNRF for resolving this situation, and intent to append the resulting
correspondence to our Environmental Impact Study Addendum that addresses natural heritage features and functions
surrounding the proposed watermain.
Best regards,
Dan Stuart
