(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

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
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.
