2 1.0 INTRODUCTION 1.1 QUALIFICATIONS 1. Matrix Solutions Inc. (Matrix) is a multidisciplinary environmental and engineering consulting company based in Calgary. They have offices nationally and are wholly employee-owned. At the end of 2014, Parish Geomorphic Ltd. merged with Matrix. Parish Geomorphic Ltd. now operates as Parish Aquatic Services and continues to provide specialized services in the assessment and restoration of rivers and streams, providing a range of services including natural heritage and ecology services, channel restoration, erosion analysis, monitoring, method and policy development, and watershed assessments. 2. I am Principal Geomorphologist with Matrix Solutions Inc. specializing in fluvial geomorphology and integrated stream restoration. Areas of activity include: characterization of the stream morphology of watercourses, assessment of potential fluvial erosion hazards, evaluation of proposed stream crossings and assessment of erosion thresholds to inform stormwater management. 3. I have 29 years of experience working in the field of fluvial geomorphology, in particular river management, Environmental Assessment and input to planning studies. 4. I am a full practicing member of the Association of Professional Geoscientists of Ontario. 5. My Curriculum Vitae is attached as Appendix A to this witness statement and outlines my academic qualifications and professional experience, which I have obtained in Canada. The OMB s Acknowledgement of Expert s Duty form is also attached to this Witness Statement. 1.2 RETAINER 6. Parish Geomorphic Ltd was retained by Bronte Green in 2012 to undertake a fluvial geomorphological assessment of the Saw Whet lands. This work included channel reach delineation of Fourteen Mile Creek and its tributaries. Meander belt width delineation was completed as well as erosion thresholds and input into various planning matters. 7. Once background information had been received, desktop work included, reach delineation and confirmation, historic assessment of aerial imagery, preliminary meander belt widths and migration rates. 8. Field work was commenced on August 30, 2012 at which time rapid assessments (RGA and RSAT) was completed for channel reaches on the Saw-Whet lands. On September 4 th and 5 th, 2012, detailed geomorphic surveys were completed for channel

3 reaches SW-2 and R75a. An additional site (Reach R-73) was assessed and surveyed on January 10, Additional field work was completed in October 2014 on tributaries in the adjacent lands that were not originally assessed. This work was to address Conservation Halton comments. Also, a site visit was completed on March 23, 2015 to assess an outlet channel that Conservation Halton had commented upon. 10. The field data in combination with the desktop assessment was used to delineate meander belt width corridors. The field work and channel migration data was applied to determine the toe erosion allowance and erosion setbacks as per the PPS guidelines. The geomorphic characterization of Fourteen Mile Creek and its tributaries was provided. The erosion thresholds for the 3 sites where detailed field work was completed were determined. Initially, channel substrate and critical shear stress and permissible velocities were used to determine an appropriate value. Based on the results and comments received, the bank material was used in the calculations. The bank values were more conservative and thus provided for the analyses and modeling of the stormwater management. Additional insight on overall channel and valley stability were provided and used to comment on potential watercourse crossings and stormwater outfalls. 1.3 DOCUMENTS TO BE REFERRED TO IN EVIDENCE 11.

Merton Tertiary Planning Study: Geomorphic Assessment Fourteen Mile Creek and Associated Tributaries by Parish Geomorphic (October 2014). 2.0 SUMMARY OF EVIDENCE 26. The watercourses within the study area (which refers to the Saw What golf course land and adjacent properties) were evaluated and characterized following accepted methods and procedures. 27. The findings that are described within our report Merton Tertiary Planning Study: Geomorphic Assessment Fourteen Mile Creek and Associated Tributaries with respect to erosion hazard limits (meander belt width) followed procedures commonly used by Conservations Authorities and were sufficient to delineate appropriate corridors and required setbacks to conform to Conservation Halton policies. 28. Based on channel characterization, appropriate sites were selected for erosion threshold determination. The analyses and results of the erosion threshold analyses followed typical approaches and utilized appropriate methods. This approach was consistent with the Merton Terms of Reference for the study and supported based on comments received from the Town of Oakville and Conservation Halton. 29. Insight, based on channel processes, was provided into watercourse crossings and stormwater outfalls. This work conformed to methods and guidelines recommended by Conservation Halton. Comments received from Conservation Halton indicated that they recommended that all watercourse crossings have a minimum of 3 times the bankfull width. This is consistent with my previous work, and is also consistent with other conservation authority guidelines for watercrossings including the Credit Valley Conservation Authority s guidelines 30. The work that has been completed to assess the channels within the Saw-What study area has been very thorough and comprehensive. It has, at a minimum, been consistent with other similar assessments and has conformed with the Terms of Reference. The additional work that was completed to address comments from the Town and Conservation Halton has been extensive and included more rigour and analyses to ensure that the function and stability of the channels in the study area will be maintain in the post-development condition.

5 3.0 ISSUES TO BE ADDRESSED 31. Issue 18 Have the regulated flooding and erosion hazards been identified in accordance with current Ministry of Natural Resources and Forestry Technical Guidelines? b) Has a compliant meander belt assessment been completed and provided? 32. Yes, the erosion hazards were assessed using the MNR Guidelines and PPS guide for natural hazards. In addition, meander belt width delineation following provincial protocols was also completed. The corridors were delineated using the PPS guidelines and the toe erosion allowance has been supported by the geotechnical work. The meander belt width for each reach was completed and used to set the MNR Redside Dace setbacks. The results have been accepted by Conservation Halton, pending receipt of detailed graphics depicted the hazard limits using 1:2000 mapping. 33. Issue 19 Have the Merton Tertiary Plan Area Technical Reports, and any other studies that were relied upon to establish stormwater management targets, been sufficiently advanced to accurately define stormwater management targets associated with quantity and erosion control, water quality, and thermal impacts that mitigate development impacts associated with the application in the context of the development potential for the entire Merton Tertiary Plan Area? 34. Yes. A comprehensive assessment of the channels that may receive stormwater was completed. Based on the field assessment, three sites were selected for detailed field characterization. The field data was synthesized and subjected to a variety of analyses (critical shear stress; permissible velocity) for both bed substrate and bank materials. The more conservative value was chosen and applied in the stormwater management facility model analyses. 35. Issue 28 Can the proposed stormwater outfalls to Fourteen Mile Creek be approved? Do they meet the regulatory requirements? 36. Yes. Based on the information that has been collected, the role of geomorphology can provide insight on the stormwater outfalls. The stability of the valley system at the locations was reviewed at the possible stormwater outfall locations. 37. Issue 45 Have baseline, during construction, and post construction monitoring requirements been articulated in sufficient detail to demonstrate that it will be able to provide meaningful information? Is there an approved monitoring plan? Has sufficient baseline monitoring been undertaken in accordance with an approved monitoring plan? 38. Yes, a proposed fluvial geomorphological monitoring plan has been developed for the Saw-Whet study area [Saw-Whet?]. The plan is consistent with other similar studies, such as North Oakville and Milton to assess the effect of the development on channel performance, function and stability. 39. Issue 46 Has it been demonstrated that the proposed road crossing of tributary 14W-W1 of Fourteen Mile Creek will have no negative impacts on the form and function of the watercourse and the existing and anticipated biological life within the natural heritage

6 system? (The following 3 points only relate to requirements to accommodate the natural channel processes.) 40. Yes. Recommendations regarding the size and configuration of the watercourse crossing have been provided from a geomorphic perspective, which would maintain channel form and function. These recommendations were provided in a memo entitled Response to Conservation Halton comments on Area Servicing Plan DSEL November 8, Issue 49 Has the application address the maintenance of fluvial geomorphology and natural channel functions of Fourteen Mile Creek and associated tributaries on the subject lands? 42. Yes. The work that has been completed initially characterized the existing conditions of Fourteen Mile Creek and its tributaries. Based on this characterization, various impact analyses, such as stormwater management implications, implications on erosion and sediment transport, infrastructure crossings and hazard limits were completed. The objective has always been to ensure the long-term maintenance and function of the channels. I am satisfied that this has been completed. 4.0 SUMMARY OPINION 43. It is my opinion that the fluvial geomorphological characterization completed for the Saw-Whet study area has been completed in a manner that was consistent with previous similar studies, conformed to the Terms of Reference, following accepted methods and practices. The results provide the appropriate insight to develop management strategies that would minimize any negative impacts to the receiving watercourses. DATED this August 27, 2015 Matrix Solutions Inc.

10 John Parish, M.A., P.Geo. PROJECT EXPERIENCE/PROFESSIONAL EXPERIENCE Dingman Creek Subwatershed Study, Delcan,London, Ontario. Senior Fluvial Geomorphologist. This basin scale assessment consisted of monitoring of channel sections, new analyses and determination of critical erosion thresholds. Integration between hydrology, hydraulics, channel processes, and aquatic habitat was integral to the study. Countryside Drive, R.V. Anderson Associates Ltd., Brampton, Ontario. Geomorphologist and Designer. After the completion of the Class Environmental Assessment for the proposed road widening, several crossings over tributaries of the Humber River were required. The crossings were sized based on geomorphic hazards. The crossings also required channel realignments, which were completed following a natural channel design approach. Eflows Guidance Manual, Ministry of Natural Resources, Ontario. Fluvial Geomorphologist. With increasing pressure on surface water resources, the Ontario Ministry of Natural Resources determined that a guidance document regarding water takings and the implications to ecological flows was warranted. The fluvial geomorphological component assisted in providing the physical hierarchy of stream types and their overall sensitivity. Guidance was also provided on specific flow targets, including minimum flows for passage and flushing flows to entrain finer sediment. Highway 407 Eastern Extension, 407EDGP, MTO, SNC, Ontario. Geomorphologist and Designer. The eastern extension of Highway 407 consisted of 32 watercourse crossings. Fluvial geomorphology was applied from the initial planning stages, through to review and regulatory approval through to construction oversight. The crossing configuration was based on a geomorphic risk assessment approach. Where channel designs were required, the geomorphic component led the process with support from fisheries and engineering. Crooks Hollow Dam Removal, Hamilton Conservation Authority, Hamilton, Ontario. Fluvial Geomorphologist. The historic Crooks Hollow Dam involved detailed sediment transport analyses, which utilized bathymetry and vertical profiles. In addition to the analyses and field work, remediation designs and channel realignment to ensure stability and fish passage were completed. Milton Monitoring, AMEC, Milton, Ontario. Geomorphologist. The Town of Milton has experienced dramatic growth within the last decade. While the urbanization followed detailed planning and environmental efforts, a systematic monitoring program was initiated to determine the implications on the receiving channels. The geomorphology component assisted in identifying the locations and has been collecting annual data for the last 5 years. 4 PARISH Aquatic Services A Division of Matrix Solutions Inc.
