In order to accommodate the parking expansion, the existing septic system is proposed to be relocated to neighbouring lot 5246 Mitch Owens, pending a lot line adjustment (consent). The existing residential dwelling on 5246 Mitch Owens is proposed to be demolished. In preparation for Site Plan Approval, a scoped EIS is required to address the potential for species at risk (SAR) to occur in the vicinity of the project site. Specifically, the scoped EIS is required to determine the potential presence of chimney swift to be utilizing the property addressed as 5246 Mitch Owens Road. The general project area is illustrated on Figure A.1 in Appendix A, while a detailed site layout and proposed development plan is provided on Figure A.2. 1.1 Objective and Scope of Work The objective of the scoped EIS presented herein is twofold; 1) to identify the presence or potential presence of any SAR and their regulated habitat within the project area, and 2) to recommend established and effective avoidance and mitigation measures to ensure that the project is completed in accordance with the provincial Endangered Species Act, 2007. To meet the objectives outlined above, the following scope of work was completed: Task 1 – Desktop Assessment Task 2 – Site Investigation Task 3 – Assessment and Reporting Report to: Plaza Reit c/o Holzman Consultants Inc. 1 Project: 100255.001 (December 8, 2020) 2.0 METHODOLOGY 2.1 Desktop Review A desktop information gathering exercise was completed to aid in the scoping of field investigations and to gather information relating to natural heritage features which may be present on the subject project or within 1 km of the subject property. An additional component of the desktop review was to assess the potential presence of species at risk (SAR) to occur on the subject property or within the study boundary based on a review of publicly accessible occurrence records and review of SAR habitat requirements and range maps. Following changes to the Ontario Ministry of Natural Resources and Forestry (OMNRF) natural heritage information request process, as of 2019, the OMNRF is no longer providing responses to these requests. As such, an information request was not submitted for this project. In lieu of a request response, the Natural Heritage Information Request Guide (OMNRF, 2018) was consulted and the data resources listed below were reviewed for relevant natural heritage feature and SAR data relating to the site. Information regarding the potential presence of natural heritage features and SAR within the vicinity of the site was obtained from the following sources: Make a Map: Natural Heritage Areas (OMNRF, 2014a) Land Information Ontario (OMNRF, 2011); City of Ottawa Official Plan (City of Ottawa, 2012a) Natural Heritage Information Centre Biodiversity Explorer (OMNRF, 2013); Breeding Bird Atlas of Ontario (Cadman et al., 2007) Ontario Herpetofaunal Atlas (Oldham and Weller, 2000); eBird Chimney Swift Species Profile (eBird, 2020a) eBird Hotspot Explorer (eBird, 2020b); iNaturalist Observation Map (iNaturalist, 2020); and Ontario Reptile and Amphibian Atlas (Ontario Nature, 2019). 2.2 Site Investigation A single field investigation was completed on December 4, 2019, from approximately 11:50 to 12:40. Conditions during the site investigation were overcast, 3°C, Beaufort wind 4 and no precipitation. The field investigation was completed by traversing the site while documenting habitat conditions and the presence/absence of SAR and their regulated habitat on-site. Photographs taken during the site investigation are provided in Appendix B. Report to: Plaza Reit c/o Holzman Consultants Inc. 2 Project: 100255.001 (December 8, 2020) 3.0 RESULTS 3.1 Desktop Screening Results Results of the desktop screening exercise are summarized in Table 3.1 below. The desktop screening exercise identified the potential for one avian, three mammalian and one plant SAR listed as endangered or threatened to occur within the project area. All five of the threatened or endangered SAR species are considered to have a moderate potential to occur within the project area. Review of the DFO SAR map indicates that no fish SAR or critical habitat have been identified within 1 km of the watercourse on-site. As outlined in the Endangered Species Act (Ontario, 2007), only species listed as threatened or endangered and their general habitat receive automatic protection. When a species-specific recovery strategy is developed, a specific habitat regulation will be established, which eventually replaces the automatic habitat protection. Species of special concern and their habitat do not receive protection under the ESA. Potential impacts associated with the proposed project to threatened or endangered species identified as having a moderate or high potential to occur on-site are discussed on a species-by- species basis in Section 3.4 below.
