1 INTRODUCTION

GeoProcess Research Associates Inc. [GRA] was retained by G.D. Vallee Ltd. to conduct a Species at Risk

[SAR] evaluation and provide a mitigation plan with respect to the culvert replacement and waterway

realignment at Structure 980909 on York Road/Haldimand Road 9, 300m east of Empire Corners,

Haldimand County. The culvert is approximately 7 m x 7 m constructed of a concrete box without

railings. The structure spans a tributary of Elsie Creek, which in turn is a tributary of the Upper Welland

River. Both east and west walls of the culvert are in‐stream. The watercourse is under the jurisdiction of

the Niagara Peninsula Conservation Authority and lies approximately 700m upstream of a Provincially

Significant Wetland. A 50m radius from the center of the bridge was evaluated for SAR presence. Refer

to Figure 1 Study Area.

The plan will demonstrate how any negative environmental effects on SAR will be mitigated, and sets

out a program for monitoring the effectiveness of the mitigation measures as it pertains to the

requirement for a mitigation plan per O. Reg. 242/08.

2 STUDY AREA

The structure is located within a rural residential area surrounded by agriculture, a golf course to the

south and a lumberyard to the northwest at the nearby intersection. The watercourse traverses the

Study Area from the northwest in a straightened fashion, with a Cattail (Typhus sp.) shallow marsh

occupying the length of the immediate upstream reach. Downstream of the culvert, vegetation includes

a complex open meadow marsh intermixed with small thickets of Grey Dogwood (Cornus racemosa) and

clusters of Hawthorn (Cratageaus sp.). The open meadow floodplain corridor is flanked by mowed

residential lawn to the west and the golf course with three large ponds to the south. From the structure

the watercourse flows directly east, joining a tributary from the golf course and continuing with natural

meander into reaches with wider riparian corridors designated Provincially Significant Wetlands

downstream.

3 PROJECT POLICY

The Endangered Species Act, 2007, S.O. 2007, Chapter 6, protects the biodiversity of Ontario by using

the best available scientific, community and aboriginal traditional knowledge and the precautionary


Page | 4

principle as its doctrine. The purpose of the Act is to identify species at risk, protect species at risk and

their habitats, and to promote the recovery of species at risk and stewardship activities which assist in

these goals.

The following mitigation plan was prepared based on the requirements of O. Reg. 242/08, s. 23.18 and

its last amendment O. Reg. 176/13, s. 14. The section “Threats to health and safety, non‐imminent”

allows for an exemption of subsection (8), clauses 9 (1) (a) and subsection 10 (1) of the Endangered

Species Act, 2007 [ESA] regarding qualified work if conditions described in subsection (5) are met and

the mitigation plan as required by subsection (6) and (7) is completed.

To qualify for the exemption under Section 23.18 the following conditions must be met:

Work to maintain, repair, remove or replace an existing structure or any infrastructure described in subsection (2), including the decommissioning of a mine, or to upgrade an existing structure or any infrastructure described in subsection (2) to meet a safety standard, if,

i. the maintenance, repair, removal, replacement, decommissioning or upgrade does not require,

A. a temporary or permanent change to the location of the structure or infrastructure, or B. a temporary or permanent extension of the area the structure or infrastructure occupies, except in the case of the replacement of an existing culvert with a new culvert that is larger than the one it replaces, or

ii. in the case of work to maintain, repair, replace or upgrade a structure or infrastructure, the work does not alter the way in which the structure or infrastructure is used or operated.

Please note that Section 23 exemptions require a Notice of Activity before the work activity commences.


Page | 5

4 PROJECT DESCRIPTION

The replacement of structure 980909 requires the complete removal of the existing structure and

replacement with a new skewed concrete box culvert. Stream re‐alignment 10 metres upstream and

downstream are proposed. The works will also include new barriers, new bridge approach guiderails and

roadwork at the approaches (new asphalt and granular base).

Additionally, a ditch clean out 100m downstream is proposed.

Policy Applicability Review The project is the replacement of an existing culvert structure with a skewed concrete box culvert. The installation requires the re‐alignment of the watercourse. The works are required to meet a safety standard. Associated works including the installation of new barriers, new bridge approach guiderails and new asphalt and granular base at both approaches is required. Additionally, a ditch clean out 100m downstream is proposed. As a replacement of infrastructure to meet today’s current safety standards in the same location, without extension or change in use, this project should meet the requirements for the exemption under Section 23.18 of Ontario Regulation 242/08. The County must provide the Ministry of Natural Resources and Forestry with Notification of the Activity and receive confirmation of that Notice from the Ministry as potential SAR habitat has been found to occur with the Study Area. A DFO review has been completed for the replacement of the culvert due to the proposed channel realignment. Additionally, channel re‐alignment requires permission from the Niagara Peninsula Conservation Authority which has been received..

5 POTENTIAL SPECIES AT RISK

5.1 STUDY METHODOLOGY

Existing information regarding SAR within the project area is summarized from data collected through a

desktop review and in‐field survey. A desktop background review was conducted using the Natural

Heritage Information Center database, Fisheries and Ocean Canada Aquatic Species at Risk Maps and

the surrounding areas SAR lists provided by the City of Hamilton and Alymer MNR. The Natural Heritage

Information Center [NHIC], operated by the Ontario Ministry of Nature Resources and Forestry, collects,

reviews, manages and distributes information on Ontario’s biodiversity. Data distributed by the NHIC is

used in conservation and natural resource management decision making and is of valued assistance for

the purpose of this report. Data on species, plant communities, wildlife concentration areas and natural

areas is made accessible to the public and professionals using generalized 1 kilometer grid units to

protect sensitive information. The mapping interface provides current and historical occurrences of SAR

within the vicinity of the proposed works location. The database also provides environmental

designations which provide insight into habitat potential including wetland, areas of natural and

scientific interests and woodlands. Results from the Fisheries and Ocean Aquatic Species at Risk Maps

and SAR lists from surrounding areas were combined with this information to assess the suitability of

habitat within the vicinity of the proposed works.

An in‐field survey was conducted based on the background information review and the potential

suitable SAR habitat identified. The study area included at 50 m radius from the center of the structure.

The in‐field survey included a sweep for any species with element occurrences in the past 50 years, as

provided by the NHIC, and a general survey for all other SAR based on the general area list and suitable

habitat conditions. The in‐field survey was conducted between December 11th and 14th, 2017. The

findings of the two‐step SAR screening are presented in table format providing an assessment of the

required habitat of potential SAR, the presence or absence of that habitat and the likelihood of the

species being present.

5.2 SCREENING FINDINGS

Details of the desktop SAR screening include an amalgamation of historical occurrence records within

the vicinity of the proposed works as per current NHIC database records, Fisheries and Oceans Canada

7 MITIGATION MEASURES

The structure replacement requires measures to mitigate harm to potential SAR, including Grass

Pickerel, Northern Bobwhite, Bobolink, Eastern Meadowlark and Henslow’s Sparrow. With the

submission of a Notice of Activity and the implementation of the following mitigation plan, the proposed

works should qualify for exemption under Section 23.18 of O. Reg. 242/08.

Based on the assessment of habitat and the likelihood of encounters on the site, the following

mitigation measures are required to meet the requirements of Paragraph 5 of Section 23.18 (O.Reg

242/08).

1. Limits of Construction;

2. Timing of activities;

3. Worker awareness; and,

4. Habitat restoration.

7.1 LIMITS OF CONSTRUCTION

Most potential impacts to SAR and SAR habitat can be avoided with the installation of reasonable limits

of construction. By keeping all works within the footprint of the existing roadway, no long term residual

effects to species habitat within the surrounding vegetation communities and watercourse will occur.

Limits of construction are to be clearly defined on all print site plans and are to be installed in

field with the use of stakes, flagging, erosion and sediment control fencing and/or exclusion

fencing.

Limits of construction are to be established prior to the arrival of any heavy machinery or any

clearing or earth works.

Limits are to be set in accordance to those advised by the DFO following project review.

All work is to be contained within the limits of construction, including machinery staging and the

storing of materials.


Page | 17

7.2 TIMING OF ACTIVITES

Consideration of the life cycles of potential SAR should dictate the timing of vegetation and structure removal.

Clearing of vegetation within the Study Area as part of proposed works should be conducted in

late summer or winter months so as not to coincide with breeding bird season (April to

August). If clearing is to proceed within the breeding bird window, the Study Area should be

screened to determine if any migratory song birds are nesting within the work zone. It is

recommended that roadside vegetation within the limits of construction be mowed prior to May

1st and regularly thereafter, until the completion of construction.

Timing windows for work within fish habitat, including fish rescue plans, are to be followed as

required by the DFO.

7.3 WORKER AWARENESS

Staff will be informed that they are working in an area with potential Species at Risk ground nesting

birds. If they encounter a bird on the ground they should leave it in place and not try to move it. The

site environmental inspector should be made aware of the observation and an assessment of the nest

should be made. If it is determined that a Species at Risk bird is nesting on or near the construction site,

measures to prevent harm to the individuals will be required.

7.4 HABITAT RESTORATION

All disturbed areas within the limits of the construction along the road’s right of way should be restored

to a vegetated condition following the completion of work. Restoration prevents the colonization of the

landscape by non‐native invasive species and provides erosion control, runoff energy dispersion, and

wildlife habitat. Re‐vegetation should be comprised of native shrub plantings to establish vegetative

cover and provide buffering capacity to the adjacent natural heritage features.

8 FISHERIES AND OCEANS SELF ASSESSMENT

The project was assessed using the DFO self assessment tool and was determined to require a review by

the Fisheries and Oceans Canada based on the project scope and the presence of aquatic Species at Risk


Page | 18

(see Appendix C). The project has been reviewed by the DFO and it was determined that it could

proceed with without causing serious harm to fish or fisheries using standard measures. The project is

required to be undertaken in a manner that protects fish and fish habitat, and should implement the

measures outlined in the ‘Measures to avoid causing harm to fish and fish habitat’. Refer to
