BACKGROUND: In 2009, the Toronto Region Conservation Authority (TRCA) completed a comprehensive process to revise the flood plain mapping along a number of creek systems across its jurisdiction. The updated Carruthers Creek flood plain mapping is a component of TRCA s

2 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 2 ongoing work to identify and protect flood vulnerable areas based on updated mapping and modeling techniques governed by the Ministry of Natural Resources. The Carruthers Creek watershed extends north from Lake Ontario for approximately 17 km and has a drainage area of approximately 3,650 ha (9,019 ac.). The watershed is elongated in a north-south direction with a length to width ratio of approximately 8 to 1. The upper reach is agricultural and the lower reaches are presently developed with a mixture of residential, commercial and industrial land uses. In early 2010, the TRCA provided the Town with updated Regulatory Floodplain Mapping for Carruthers Creek. The new floodplain mapping indicated a significant spill through the Pickering Beach Neighbourhood to Lake Ontario. On June 24, 2010, Council awarded the contract for the Environmental Assessment (EA) of the Carruthers Creek Flood Management and Analysis to Cole Engineering Group Ltd. The TRCA was involved throughout every aspect of the project. This EA focuses on flood remediation solutions for the Pickering Beach Neighbourhood. Due to the potential impacts associated with the new flood limit there are now development restrictions on the properties within the flood regulated area. Work on private property is now subject to TRCA review and approval. DISCUSSION: The EA includes a review and update of the hydrology and mapping for the watershed and identified potential risks to hydrology, including approved urban areas and the long term potential for urbanization in the Carruthers Headwaters. It identifies options to mitigate downstream flood risks based on existing, approved and potential urban developments including the proposed Northeast Pickering Urban Area as identified within Regional Official Plan Amendment 128 (ROPA 128). It also identifies solution(s) to mitigate/remediate the risk of flooding within the watershed, focusing on the Flood Remediation Area as shown in Figure 1.

3 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 3 Figure 1 Flood Remediation Area The EA was undertaken in four phases, as identified below. Phase One Identification of Problems or Opportunities The first phase included the identification of a problem/opportunity statement and an inventory of existing conditions. A clear and concise problem statement was prepared, to confirm and identify the cause and impact of flooding within the Pickering Beach area. The goal of the EA is to identify mitigation methods and alternatives for eliminating, reducing and/or managing this spill. Phase Two Selection of Alternative Solutions The second phase included the evaluation and selection of the alternative solutions. This work was the focus of the first Public Information Centre (PIC) meeting held on December 9, The presentation outlined the work to date and the criteria used in evaluating the alternative solutions. The methodology used to evaluate the alternative solutions was based on natural, social, economic, and technical criteria in accordance with the Class EA requirements. Phase Three Selection of Preferred Solution(s) and the Preferred Concept Design The third phase involved the selection of preferred solution(s) and the generation, evaluation and selection of a preferred conceptual design, supported by the assessment work of the Project Specialists and Engineers. Hydrology Modeling Update As part of the project scope, the hydrology model was updated and calibrated using advanced modeling techniques and new monitoring information. The hydrology model was updated to match the 2008 condition and calibrated to seven storm events from 2006 to 2009 based on precipitation and stream flow data provided by the TRCA. Through the calibration process, the model produced lower flows than the previous uncalibrated 2007 hydrology update prepared by Philips Engineering. This was attributed to: i. More data being available for the calibration process (three precipitation gauges were used from the Duffins Creek Watershed to the west and three from the Lynde Creek Watershed to the east); ii. iii. A customized Distributed Rainfall Modeling Technique developed by Cole Engineering Group Ltd. was used to determine rain within Carruthers Creek from the surrounding rain gauge information; The model was calibrated to the stream flow data gathered after the previous hydrology model update in This resulted in an approximate flow reduction of 35% below the regulatory event at the Shoal Point Road bridge. Hydraulic modeling was updated based on available elevation data and the revised flows from the hydrology modeling. As a result of this hydrology and hydraulic modeling update, the number of affected lots within the Pickering Beach Neighbourhood has been reduced from 91 to 50.

4 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 4 The revised Regional Regulatory Flood limits 2012, attached as Appendix A have been plotted against the Regional Flood lines 2009 for reference. This would represent the Do Nothing alternative. Preferred Alternative(s) Through the evaluation process, three alternatives would effectively remove the Regional Flood Regulation limit from the Pickering Beach Neighbourhood, these alternatives are: i. Upgrades to the existing Shoal Point Road Bridge; ii. iii. Construction of a Flood Control Landform; and, Lowering Floodplain Elevation. 1. Upgrades to the Existing Shoal Point Road Bridge The current Shoal Point Road Bridge, as shown in Figure 2 creates an obstruction to the regulatory flows. Additionally, the channel constricts around the bridge narrowing the crosssection available for water conveyance. The existing bridge would be over topped in a Regional Flood Event, and this overtopping elevation is the primary driver for the upstream flood elevations. Figure 2 Existing Shoal Point Road Bridge In order to alleviate flood risk associated with the Regional Regulatory Flood event, the existing bridge will require reconstruction in order to allow the Regulatory Regional Flood event to pass under the bridge deck and remedy the backwater impacts upstream. This can be achieved by constructing an approximate 50 metres (164 ft.) span bridge, or providing an additional 40 metres (130 ft.) of span through the use of box culverts to allow additional flow conveyance on either side of the existing bridge structure. While a reconstructed bridge could remedy conveyance inefficiencies and alleviate the spill risk associated with the Regional Regulatory Flood event in the Pickering Beach Neighbourhood, the preliminary costs associated with replacement of the bridge are estimated in excess of $3.7 million, based on this concept. This estimate would need to be refined after the detailed design is completed. The works anticipated would include the bridge upgrade, the proposed earth works to opening up the floodplain at this location and restoration.

5 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 5 2. Construction of a Flood Control Landform A Flood Control Landform could be created to reduce this flooding risk. It is proposed that it be constructed primarily within a 1.26 ha (4 ac.) property currently under private ownership (See Figure 3). This property is currently located within the regulatory floodplain and would require acquisition by the Town. Some local filling along back yards would also be required to prevent a spill from moving around the landform. The extent of fill is shown in Figure 3.

6 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 6 Environmental Assessment Carruthers Creek Floodplain and Analysis Figure 3 Conceptual Plan of Proposed Works Town of Ajax Planning and Development Services Date: May 22, 2012 The landform is estimated to be 2.0 m in height at its highest location and tapering off towards the ends, eventually terminating into existing grade outside of the valley. Based on TRCA s experience with the Ministry of Natural Resources (MNR) with a similar project in the City of Toronto, strict design guidelines pertaining to scour protection, prevention of lateral migration of flood flows, hydrostatic uplift and erosion are required to allow MNR to consider the landform as a permanent structure. No significant vegetative plantings such as trees would be allowed on the landform and regular maintenance would be required (See Figure 4). Figure 4 - Conceptual Cross Section of the Proposed Landform The construction of this landform would mean that local drainage from properties along Seabreeze Road and Beachview Street would require a new outlet for stormwater. It is proposed that local drainage be redirected to a new ditch inlet catch basin or similar inlet device and convey these flows in a new storm sewer located on Ruthel Road. This sewer would outlet to an existing swale within Paradise Park at the corner of Ruthel Road and Ebony Street and could be incorporated as a water source for wetland works through the future Paradise Park reconstruction project. Since the former Ruthel Road road allowance north of Seabreeze Road would be utilized as a route for this new storm sewer, a portion of this property would need to be acquired by the Town. Additionally, the existing drainage easement located on the western limit of 2954 Seabreeze Road will have to remain as a route for emergency overland flow. A conceptual plan and profile of the proposed sewer is shown in Figure 5. The preliminary costs associated with construction of this landform are estimated at $1.6 million which includes local drainage improvements such as storm sewer construction and restoration. This estimate is exclusive of land acquisition costs and is based upon the concept. This estimate will need to be refined after the detailed design is completed. The estimated concept costs are detailed in the Preliminary Design Report.

7 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 7 Figure 5 Conceptual Plan and Profile Ruthel Road Storm Sewer 3. Floodplain Lowering Lowering the floodplain elevation provides a minor decrease to the spill area through the Pickering Beach Neighbourhood. This alternative provides significant opportunities for environmental benefits including frequent wetting of the floodplain, the reinstatement of wetland vegetation species and improved fish habitat and spawning grounds. Construction costs are estimated at $220, Preferred Solution Based on an evaluation of social considerations, effectiveness and economic feasibility, the preferred solution is the combined alternatives of a Flood Control Landform and Floodplain Lowering. The landform is capable of fulfilling the objectives of the EA by removing the spill risk through the Pickering Beach Neighbourhood based on the current Regional Flood Limits. The landform is a less expensive alternative than the reconstruction of the Shoal Point Road bridge and it presents opportunities for enhanced environmental features within the Carruthers Creek valley. This option is not expected to impede the existing opportunities for public access, while the construction of a new bridge would likely result in the closure of Shoal Point Road for approximately 9 months, subject to the timing of environmental approvals. The preferred solution has been endorsed by the TRCA. Phase Four Preparation of Environmental Study Report (ESR) The Environmental Study Report (ESR) documents the planning and design process and conclusions reached for the Carruthers Creek Flood Management and Analysis Municipal Class

8 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 8 Environmental Assessment. The ESR documents all the activities undertaken under the Class EA process. Once endorsed by Council the ESR will be placed on public record for a period of thirty (30) calendar days for public and agency review. During this period, concerned individuals have the right to raise and discuss issues or to request a Part II Order. A Part ll Order may require an Individual EA to be carried out and submitted to the Ministry of the Environment for review and approval. The decision on whether the project should be subject to a Part ll Order rests with the Ministry of Environment. Assuming there are no outstanding Part ll Order requests, the Municipality may proceed to implementation. Companion Reports As a requirement of this Class EA, the following reports were prepared by Cole Engineering: i. Hydrology Update Report - Carruthers Creek Watershed; ii. Peer Review of the 2009 R.J. Burnside Digital Floodplain Mapping Report; iii. Flood Line Mapping Report - Carruthers Creek Watershed; iv. Regional Official Plan Amendment No. 128 Impact Report; v. Flood Emergency Preparedness Plan; vi. Preliminary Design Report. The reports highlighted in blue are available on line at: Reports.asp Regional Official Plan Amendment No. 128 Impact Report The Region of Durham, through its Official Plan Review and Growth Plan conformity exercise adopted an Amendment to the Regional Official Plan to implement a number of changes to the Region s planning policies and urban structure. Regional Official Plan Amendment No. 128 (ROPA 128) incorporated numerous changes including new population and employment projections to 2031, and various urban boundary expansions. Of concern to this EA is the potential for development within the proposed Northeast Pickering Urban Area, which would fall directly within the headwaters of the Carruthers Creek watershed (see Figure 6). ROPA 128 would allocate a population of approximately 29,000 people to Northeast Pickering. The majority of which would be located within the Carruthers Creek headwaters. ROPA 128 was adopted by the Region on June 3, 2009 and referred to the Ministry of Municipal Affairs and Housing for approval. On October 27, 2010 the Ministry of Municipal Affairs and Housing released its decision on ROPA 128. This decision included a number of components including the deletion of the proposed Northeast Pickering Urban Area and a deferral of other proposed urban boundary expansions, along with modifications to policies and other schedules. On November 15, 2010 the Region of Durham appealed the decision of the Ministry of Municipal Affairs and Housing on ROPA 128 to the Ontario Municipal Board (OMB). Other appeals were filed by landowners within the Northeast Pickering Urban Area as well as elsewhere in Durham. The Ministry of Municipal Affairs and Housing decision was not appealed by Pickering or Ajax. Ajax, Pickering and others have been granted party status for the OMB hearing.

9 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 9 Figure 6 Proposed Northeast Pickering Urban Area and the Carruthers Creek Watershed The timeframe for the commencement of a hearing on ROPA 128 remains uncertain, due in large part to a parallel process which is underway for the planning of the Seaton Community in North Central Pickering. The Province has declared a provincial interest in Seaton and has assigned population and employment targets that will directly affect the Region s urban area land needs within ROPA 128. This parallel process (Amendment No.1 to the Central Pickering Development Plan) and OMB appeals regarding Seaton remain pending. An OMB Decision on ROPA 128 will follow this parallel process, but timeframes have not yet been determined. Analysis The Town has a direct interest in the potential for urban development as proposed by the Region in ROPA 128 due to the potential for downstream impacts within Ajax. Cole Engineering was instructed to undertake an analysis of the potential for urban development and the implications for the study area. A Future Condition Stormwater Model incorporated the proposed ROPA 128 development for the Northeast Pickering Urban Area to evaluate the potential impacts on watershed hydrology. It was developed based on the prescribed land use established in ROPA 128. The parameters used are consistent with TRCA hydrology and hydraulic modeling practices. Significant increases in flood flows within the Carruthers Creek Watershed were identified. There was an increase in flows for the 2 through 100 year storms as well as an approximate increase in peak flows of 45% for the Regional storm event at Lake Ontario. The largest flow increase was observed upstream of Rossland Road with an increase of 132% for the Regional storm. The large increases in flow can be attributed to the increase in runoff generated from the significant increase in impervious area, as well as the substantial decrease in the time to peak associated with the developed condition.

10 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 10 This significant change in flow will increase flooding depth within the Pickering Beach Neighbourhood including impacting approximately an additional twenty-seven properties and twenty-five buildings. At the three (3) locations analyzed along Ruthel Road, the average flooding depths at the road centreline increases from 0.44 m to 0.84 m while the average depths at the property lines went from 0.17 m to 0.56 m. With the construction of the proposed Flood Control Landform, the additional freeboard included in the design would provide protection for an additional 30% increase in flows. However, the proposed Northeast Pickering Urban Area would represent an approximate 45% increase in flows from existing approved land uses, which would overtop the Flood Control Landform. The resulting flood line from this instance has not been confirmed, but may be representative of a Do Nothing option resulting in continued flood risk to properties in the Pickering Beach area. Flood flows and protection work are considered for the extent of the approved Official Plan for the Town of Ajax. Future development within other areas of the Carruthers Creek watershed, specifically the Northeast Pickering Urban Area have not been accommodated within the preferred solution. With the newly calibrated hydrology model, the ROPA 128 development area would produce Regional Regulatory Flood flows at approximately 220 m 3 /s. This flow would be similar to the uncalibrated 2009 Regional Food Line flows that previously existed prior to the start of this EA. Given the current uncertainty regarding the ROPA 128 process, and the potential for change that may occur through the various OMB appeals, it would be premature to advance land acquisitions and capital works to provide for an outcome which may not be effective in addressing a Regional Storm event under a condition whereby Northeast Pickering is urbanized. Flood Emergency Preparedness Plan A Flood Emergency Preparedness Plan (FEPP) has been prepared to outline steps for monitoring and responding to emergency conditions arising from high water levels of Carruthers Creek within the Town of Ajax until the Preferred Solution(s) can be installed. The FEPP is a framework that ensures the Town is prepared for the possibility of a Regional Storm, and a response to a Regional Storm under existing conditions. Using the 2008 Provincial Flood Forecasting and Warning Implementation Guidelines to reduce the risk to life and damage to property due to flooding, the FEPP outlines the process where local agencies and the public are provided with notice, information and advice so that they can respond to potential flooding and flood emergencies. The FEPP is intended to be used as a tool to support and coordinate with the existing Town of Ajax Emergency Response Plan (2007) and the TRCA Flood Contingency Plan (2009). Interim Development Approvals Screening for the Pickering Beach Neighbourhood At present all development applications are subject to a TRCA screening process for properties located within the Regional Flood Line. The TRCA is required by provincial legislation to regulate development on the lands within flood plains. When the TRCA re-drafted the flood lines in 2009, there were 91 properties and 59 buildings located within the Regional Flood line. As reported at the June 9, 2011 meeting of General Government Committee, and at the subsequent public open house, the hydrology model was updated and calibrated using advanced modeling techniques and new monitoring information. Through the calibration process, the model produced lower flows than the previous 2007 hydrology update prepared by Philips Engineering. This is attributed to:

11 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 11 i. More data being available for the calibration process (three precipitation gauges were used from the Duffins Creek Watershed to the west and three from the Lynde Creek Watershed to the east; ii. iii. A custom Distribution Rainfall Modeling Technique developed by Cole Engineering Group Ltd. Was used to determine rain within Carruthers Creek from the surrounding rain gauge information; The model was calibrated to the stream flow data gathered after the previous hydrology model update in This resulted in a regulatory flow reduction within the creek of approximately 35% as observed at Lake Ontario ( cubic metres per second to cubic metres per second). Hydraulic modeling was updated based on available elevation data and the revised flows from the hydrology modeling. This represented the Do Nothing alternative. The number of properties and buildings located within the 2012 Regional Flood line was substantially reduced to 50 properties and 22 buildings respectively (See Table 1). Fortunately, due to the new smaller Regional Storm Flood plain location, depths and velocities now allow for greater flexibility in managing and regulating development within Flood Plain Boundary. The TRCA screening process will continue on a site by site basis with individual detailed assessments of the properties as development applications are received by the TRCA. The screening process will evaluate any changes to grading and structures that are located in the flood plain and any resulting change to the movement and location of flood waters. TRCA will ensure that there are no impacts to the flood vulnerability of adjacent properties as a result of development projects. There are only 18 properties that have been identified as properties that have limited options as far as development opportunities. Theses properties are identified by blue shading on the attached Figure 7. Out of the 18 properties, only of 2 properties are vacant and would be very limited as far as opportunities available for future developments in accordance with TRCA criteria.

13 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 13 Next Steps Should this report be endorsed by Council, the ESR will then be placed on the public record for a period of thirty (30) calendar days, where the public and review agencies will have an opportunity to review it. Assuming there are no outstanding Part ll Order requests, the Town will then be able to proceed to the final implementation phase. As part of the recommendations within this report, the EA and supporting documentation will be forwarded to the Region and the City of Pickering in order to articulate the Town s concerns regarding how flood risks in the Pickering Beach community would be worsened through the potential urbanization of the Carruthers headwaters. Since the preferred solution is not identified within the Town s Long Range Capital Forecast, and given the preferred landform and floodplain lowering solution will not accommodate increase of flows from a decision to include Northeast Pickering Urban Area, it would not be appropriate to commit to the project at this time. The cost of the preferred solution, including land acquisition and capital improvements is expected to be in the $2 million range. A financial commitment of this magnitude would need to be carefully weighed against all other municipal projects and levels of service. Under Section 450 of the Municipal Act and based on case law the Town is not liable in negligence if it decides not to construct the landform as long as the decision not to construct is made in good faith. A good faith decision could include a decision based on financial costs or constraints in carrying out such work. FINANCIAL IMPLICATIONS: There are no financial implications associated with the receipt of this report. The finalization of the Class EA will assist with future planning and review of funding through the Town s annual budget process. The preferred solution is not currently identified in the 2012 budget nor in the 2013 to 2016 Long Range Capital Forecast. COMMUNICATION ISSUES: The first Public Information Centre (PIC) was held on December 9, 2010 to engage, solicit discussion and generate comments from the community and stakeholders. The second PIC was held on June 9, 2011 which provided an overview of the preferred alternatives. One-on-one meetings were held with TRCA, Town staff and the 14 of the 18 residents of the Pickering Beach Neighbourhood who own properties most affected by the new floodlines. These meetings were held during the week of April 23, 2012 to advise them of the limitations on their properties and to address specific questions that directly pertained to their individual properties. Staff contacted residents via letter and if no response was received, followed up by telephone and door-to-door to ensure contact was made. A Drop-in Centre was held on April 24, 2012 for all residents affected by the 2009 Regional Floodline mapping in order to release the 2012 TRCA Regional Flood lines. Viewing stations of the new mapping and opportunities for dialogue for development options and limitations to properties was provided. To date, comments have been received from the community, stakeholders and government agencies. Cole Engineering in conjunction with the Town and TRCA have provided responses in a timely fashion.

14 Subject: Environmental Assessment Carruthers Creek Flood Management and Analysis P a g e 14 In addition to public consultation, the following stakeholders were contacted for input: Runnymede Development Corporation Limited The Sernas Group Ontario Reality Corporation Ministry of the Environment Ministry of Tourism and Culture Ministry of Natural Resources Ontario Ministry of Aboriginal Affairs Indian and Northern Affairs Canada Department of Fisheries Ministry of Municipal Affairs and Housing Ministry of Transportation First Nations and Metis Consultation: - Alderville First Nation - Beausoleil First Nation - Chippeqwas of Rama First Nation - Curve Lake First Nation - Hiawatha First Nation Region of Durham PMG Planning Consultants Transport Canada Ajax Heritage Inventory SLR Ecologist The Public Information Centres (PICs), the Drop in Centre and this meeting were advertised on the Town of Ajax community page in the News Advertiser, mailed to affected stakeholders and other government agencies and all presentations have been placed on the Town s website. All issues raised by these stakeholders and residents have been identified and addressed in the Environmental Study Report. CONCLUSION: In summary, the Class EA demonstrated a positive result in reducing flood flows using new detailed monitoring data. This provided a solid foundation on which to prepare conceptual design alternatives and identified a preferred solution for remediation of the spill impacts in the Pickering Beach Neighbourhood. The Class EA also evaluated the impacts to the floodplain as a result of proposed development elsewhere within the Carruthers Creek watershed and will provide important information for future land use decisions. It is recommended that implementation of the preferred solution not proceed at this time. The uncertainties regarding Northeast Pickering Urban Area need to be addressed and the financial commitment considered in the context of the Town s budget process. Russ Corby, C.E.T.
