    1.0 INTRODUCTION

    1.1 Executive Summary and Report Purpose

    DST Consulting Engineers Inc. (DST) was retained by KDSA Development Corporation (KDSA), to conduct a Detailed Environmental Impact Statement (EIS) and selected Species at Risk (SAR) surveys for the Burnstown Bridge Property (Figure 1). The EIS was completed to support the due diligence and plan of subdivision application for the development of approximately 17.4 hectares (43 acres) of land in McNab/Braeside, Ontario. The subdivision plan will consist of approximately 20 to 40 units on 17.4 hectares of land, and will be serviced with wells/septic systems. The property is adjacent to the Madawaska River, east of Building Supply Road and southeast of the Burnstown Bridge, parallel to the south side of the river for approximately 1400 m of shoreline (Figure 1). As specified in the Township of McNab/Braeside Official Plan a 30 m setback from the high water mark of the Madawaska River will be maintained for any waterfront lots (Township of McNab/Braeside 2009). Within this setback the majority of vegetation will be retained, subject to the restrictions on shoreline development outlined in the Official Plan of the Township of McNab/Braeside Official Plan, which encourages avoiding disturbance of the natural vegetation and soil mantle within the setback area, but does allow for building of boat launch facilities and boat docks (Township of McNab/Braeside 2009). The Ontario Power Generation (OPG) owns the waterfront land up to the high water mark and hence any future placement of waterside structures would be subject to agreement with OPG. Future dock or boat launch construction may be achieved if land is leased from OPG by future land owners. Any future shoreline development would be subject to OPG’s leasing rules, which will typically dictate that only temporary seasonal docks will be allowed. These limitations on shoreline development are intended to minimize impacts on the shoreline from future waterfront lot development and it is not anticipated that high impact or permanent shoreline development will occur.

    DST conducted formal agency consultation to support this EIS and reviewed the information provided by the Ontario Ministry of Natural Resources (OMNR), the Natural Heritage Information Center (NHIC search) and the Country of Renfrew. Consultation with OMNR indicated the potential for several species at risk (SAR) birds and/or their habitats to be present on Site including Whip Poor Will, Cerulean Warbler, Common Nighthawk and Bald Eagle, as well as SAR plants including American Ginseng and Butternut, and one SAR reptile - Northern Map Turtle. To support the Detailed EIS requirements, DST conducted SAR field surveys to document and assess the potential presence of these SAR and the presence of other wildlife. All SAR surveys were conducted according to OMNR survey protocols for these species. During these surveys Butternut Trees were
