THE AMENDMENT WAS NOT CARRIED

THE MAIN MOTION WAS CARRIED

BACKGROUNDCorrespondence via electronic mail (E-mail) has been received from Mr. Dinesh Bilimoria who wishes to purchase a fragment of TRCA-owned property located at the rear of 146 Robirwin Street in the hamlet of Stouffville. A copy of the E-mail and a plan from Mr. Bilimoria is outlined in Attachment 1. TRCA lands at this location are part of a larger parcel acquired from Mattamy (Little Rouge Creek) Limited on March 8, 2011, under the Greenlands Acquisition Project for 2011-2015, Flood Plain and Conservation Component, Rouge River watershed.

At Executive Committee Meeting #7/12, held on September 7, 2012, Resolution #B119/12 was approved as follows:

THAT the potential disposal of a fragment of Toronto and Region Conservation Authority (TRCA)-owned property located at the rear of 146 Robirwin Street, Town of Whitchurch-Stouffville, be referred to TRCA staff for review and discussion in accordance with established TRCA policies;

AND FURTHER THAT a report be brought forward to the Executive Committee at a future date recommending further action.

This request was circulated to staff of the Town of Whitchurch-Stouffville, the Regional Municipality of York and TRCA for review and comment. The following comments have been received:

191

TRCA Staff Comments The subject residential lot at 146 Robirwin Street was created as part of draft plan of subdivision 19T-04005 developed by Mattamy (Little Rouge Creek) Limited. The analysis which defined the boundary between the developed lands and the adjacent Greenlands System (now under TRCA ownership) was presented in a report titled: "Mattamy Stouffville / Maio Environmental Impact Study", prepared by LGL Environmental Research Associates, dated April 2005 ("LGL Report").

The rear lot line of the subject lot was established as the "10m offset from Regional Flood Line" constraint. In addition to the adjacent Natural Hazard in the form of the Regional Flood Line associated with the Little Rouge Creek Tributary, the lands behind 146 Robirwin Street form part of the Town and Regional Greenland system and are designated as "Oak Ridges Moraine Plan Area Key Natural Heritage and Hydrologically Sensitive Features", as identified on Schedule H of the Town of Whitchurch-Stouffville Official Plan.

Furthermore, the LGL Report identifies the TRCA lands at the rear of 146 Robirwin Street as a Dry-Moist Old Field Meadow and are approximately 20 metres north of a White Cedar Mineral Thicket Swamp. The creek itself is located roughly 50 metres south of the rear lot line.

Planning and Development staff is of the opinion that the portion of TRCA lands requested for disposal should be retained in TRCA ownership to protect the adjacent private residential lands from riverine flood hazards as well as for Oak Ridges Moraine natural heritage conservation and protection, as required in the Oak Ridges Moraine Conservation Plan, the Regional Official Plan and the Town's Official Plan and Zoning By-law.

Town of Whitchurch-Stouffville Staff CommentsTown staff concur with TRCA's Planning and Development staff comments and recommendation to retain ownership of the subject TRCA-owned land.

Regional Municipality of York Staff CommentsYork Region staff agree with TRCA's Planning and Development staff comments and recommendation to retain ownership of the subject TRCA-owned land.

CONCLUSIONFor the reasons noted in the above comments, staff is recommending that the subject parcel be retained by TRCA for conservation purposes.

A plan illustrating the location of the subject lands is outlined in Attachment 2.

RES.#A86/13 - HIGHWAY 407 EAST EXTENSION DETAILED DESIGN OPTIMIZATION PROCESSRequest that the Minister of the Environment confirm that provincial interests related to natural hazards ,natural heritage and water management are being addressed during the detailed design and construction process for the Ministry of Transportation's (MTO) Highway 407 East Extension project, and that the interests of the citizens of Ontario are addressed.

Moved by: Colleen JordanSeconded by: Dave Ryan

WHEREAS in June 2010 the Ontario Minister of the Environment (MOE) granted approval of the Highway 407 East Transportation Corridor Environmental Assessment (407 East Extension EA) to allow for the extension of Highway 407 by 50 km from Brock Road in the City of Pickering to Highway 35/115, within the jurisdictions of the Toronto and Region Conservation Authority (TRCA), Central Lake Ontario Conservation Authority (CLOCA) and the Ganaraska Region Conservation Authority (GRCA);

AND WHEREAS detailed design and construction is proceeding at an accelerated rate with Phase 1 scheduled for completion in late 2015, including an area from approximately Brock Road in the City of Pickering to Harmony Road in the Town of Oshawa;

AND WHEREAS through the environmental assessment process, TRCA provided technical clearance on preliminary issues related to natural hazards, natural heritage and water management with the expectation that TRCA review would continue through the detailed design stage;

AND WHEREAS the MTO Environmental Protection Requirements for Transportation Planning and Highway Design, Construction, Operation and Maintenance (2010) specifically outlines provisions for highway design and construction meeting the Conservation Authorities Act;

AND WHEREAS TRCA has been advised that modifications are being made to the highway design approved through the Environmental Assessment (EA), including changes to alignment and size of crossing structures;

AND WHEREAS MTO recently advised TRCA, CLOCA and GRCA that they are to have a limited technical review role in the detailed design process for the Highway 407 East Extension project;

AND WHEREAS TRCA is concerned that its provincially delegated responsibility of ensuring risk to life and property through flooding and erosion, and thereby the protection of the citizens of Ontario, are not being addressed in the Highway 407 East Extension project;

AND WHEREAS TRCA is concerned that its mandated responsibility to undertake watershed management programs to encourage the conservation and restoration of natural resources are not being addressed in the Highway 407 East Extension project;

196

THEREFORE LET IT BE RESOLVED THAT TRCA requests the Minister of the Environment, as the provincial authority for the Highway 407 East Extension Environmental Assessment, to provide clear direction to the Ministry of Transportation as to conservation authority roles and responsibilities in the detailed design and construction process for this project so that assurances made during the environmental assessment are confirmed;

AND FURTHER THAT the Town of Ajax, the City of Pickering and the Regional Municipality of Durham, CLOCA, GRCA and Conservation Ontario, as well as the Premier of Ontario, Ontario Ministry of Transportation, Ontario Ministry of Natural Resources, Infrastructure Ontario, Ontario Ministry of Municipal Affairs and Housing, Environment Canada and Fisheries and Oceans Canada be so advised.

CARRIEDBACKGROUNDThe Highway 407 project was initiated by MTO in the 1980s, and was eventually divided into four sections: Central, 407 West, 407 East Partial and 407 East Extension. During the detailed design review of the Central and East Partial sections, the province established an optimization process whereby TRCA reviewed and provided sign-off on significant issues, including watercourse crossings, structure modifications, impacts to flooding and erosion, natural channel designs, geomorphological assessments, hydraulics, stormwater management plans, environmental management plans, and vegetation restoration plans. TRCA staff is concerned that this process is not being followed in the Highway 407 East Extension project.

Significant Natural FeaturesThe Highway 407 East Extension project crosses 12 watersheds, including 79 watercourses. In TRCA's jurisdiction it will cross both the Duffins and Carruthers creeks watersheds. The highway will be constructed on the Oak Ridges Moraine, in an area that is predominantly a groundwater recharge . Many of the watercourses are coldwater streams and provide habitats for a diverse and sensitive aquatic community. The highway will cross or is adjacent to one ANSI (the Duffins Creek Valley Regional Life Area); five provincially significant wetlands (Solina Wetland, Lynde Creek Coastal Wetland, Harmony Farewell Iroquois Beach Wetland, Maple Grove Wetland Complex and Whitby-Oshawa Iroquois Beach Wetland Complex); 19 Environmentally Significant Areas (ESA) (none of which are in TRCAs jurisdiction) and a number of unevaluated wetlands.

407 East Transportation Corridor EA (Highway 407 Extension)In 2010, after five years of study, the Ministry of the Environment (MOE) granted approval of the 407 East Extension. The project involves a 50 kilometre extension of the highway, from Brock Road in the City of Pickering to Highway 35/115, and includes two north-south links to connect with Highway 401 (Attachment 1). TRCA, CLOCA and GRCA were involved in the review of the EA and their comments on the final EA and responses were included in the MOE approvals report.

197

The highway corridor itself will be constructed in two phases. Phase 1 involves the construction of 32 km of highway from east of the Brock Road interchange in Pickering to east of Harmony Road in Oshawa, and is scheduled to be completed in 2015. The design and review for Phase 1 is currently underway as is preparation of the land and clearing. Segment A-1 falls within the TRCA jurisdiction. The remaining segments of work fall within CLOCA's jurisdiction. The remaining 18 kilometres of highway will be built as part of Phase 2, and is within CLOCA's and GRCA's jurisdictions.

EA CommitmentsSection 8 of the EA provides commitments, including but not limited to:

detailed design of bridges and culverts, channels, stormwater management and drainage,

trails and utilities; and,monitoring of ecological sensitive features, including groundwater, upland vegetation, fish

and fish habitat, significant species and areas, and landscape connectivity.

Section 9 of the EA summarizes project commitments and monitoring. Strategies that relate to conservation authorities (CAs) include:

confirmation of a Butternut Tree Strategy (CA input relates to relocation lands);

salvaging and relocation of rare vegetation species;

development of vegetation and restoration plans;

consultation on edge management plans;

refinement of stormwater management facilities and determination of outlet structures; and,

finalization of stormwater management plans.

During the EA, there was a significant amount of work completed with respect to the design of the bridges and culverts, as well as the associated channel works. This included assessments of, and design considerations for, geomorphological, hydrogeologic, fisheries, natural features, wildlife and hydrotechnical (hydrologic modeling, water level clearances, impacts on upstream and downstream water levels, velocities for a range of storm events including the regional). TRCA was assured that it would have the opportunity to review the design and construction reports (DCR) that would be required during the detailed design stage.

Responsibilities of Conservation Authorities

In the review of detailed design of provincial projects, CAs maintain a number of review responsibilities including:

Provincially Delegated Responsibility for Natural Hazards

Conservation Ontario (CO), in partnership with the Ministry of Natural Resources (MNR) and the Ministry of Municipal Affairs and Housing (MMAH), signed Memorandum of Understanding (MOU) to ensure projects prevent, eliminate, or reduce the risk to life and property from flooding and erosion.Provincially Mandated Responsibility Watershed Management for the Conservation and

Restoration of Natural Resources CAs have a mandated responsibility to undertake watershed management programs to encourage the conservation and restoration of natural resources.

198

The Ontario Ministry of Transportation (MTO) Environmental Protection Requirements for

Transportation Planning and Highway Design, Construction, Operation and Maintenance(2010) CAs are to provide comment on highway design and construction issues related to surface water, including impacts to existing water balance, protecting upstream and downstream human and non-human land and water uses, impacts to the quality of surface water and changes in erosion potential and flood risk. Municipal Advisory Services

CAs provide environmental advisory services to municipalities through service agreements or memorandums of understandings with participating municipalities or as part of its approved program activity, covering areas of technical expertise natural heritage, natural hazard and water management. TRCA has a memorandum of understanding with the Regional Municipality of Durham to provide these services.

RATIONALETRCA, together with CLOCA and GRCA share a concern that provincial obligations to ensure the Highway 407 East Extension project meets technical standards related to natural hazards, natural heritage and water management are not being addressed. An open review process is currently not being executed between MTO and the CAs.

Fulfillment of Provincial ObligationsIt is the responsibility of CAs to act on behalf of those within their jurisdiction to prevent, eliminate or reduce the risk to life and property from flooding and erosion and to encourage the protection and regeneration of natural resources. CAs are responsible for maintaining and updating the flood modeling on a watershed scale, and have the local knowledge and work with our municipal partners to ensure the interests of the public are addressed. CA's offer a strong presence in the communities and have developed good relationships with local and municipal residents and staff.

It is TRCAs understanding that in order to fulfil the obligations of the EA, as well as MOE's Notice of Approval to Proceed, MTO and its consultants would embark on a process that would be similar to, if not identical to, the process required by the MOE for the Highway 407 West and Highway 407 East Partial sections. As resolved through ministerial direction for these earlier sections of the highway, CA review and comment on detailed design issues related to natural hazard and water management was required in order for the Minister of the Environment of the time to ensure, on behalf of the citizens of Ontario, that these public interests were addressed. On April 5, 2013, TRCA, CLOCA and GRCA received a joint letter from MTO that advised staff that MTO would not be seeking CA review and concurrence with design changes. A copy of the full letter is provided as Attachment 2.

199

TRCA staff is concerned that there is a lack of CA input in the Highway 407 East Extension project, and that this lack of input into the detailed design process may result in issues related to natural hazard, natural heritage or water management not being addressed. In the review of the first DCR, staff noted that the structures and channel design that were approved in the EA are being modified and that there was insufficient detail provided and as such TRCA was unable to undertake a comprehensive review. Although infrastructure projects undertaken by the Crown are exempt from regulatory approvals under the Conservation Authorities Act, the best practice of provincial agencies has routinely been to engage CAs in order undergo a full technical review on a best efforts basis. It was noted in the EA that the DCRs would be provided to the CAs including updated models and hydraulics. The DCRs have been provided, but are lacking that detailed information required for a comprehensive review, including the modeling. Other information including stormwater management, natural channel designs, and vegetation removal and restoration plans that were routinely provided to TRCA in past MTO projects, and committed to in this project, are not being provided to CAs for the 407 East Extension.

At this time, TRCA is concerned that the construction of the Highway 407 East Extension project may cause flooding or erosion both downstream, and immediately upstream of the project area. With proper study and modelling review, the residents of the Regional Municipality of Durham, the City of Pickering and the Town of Ajax, can be assured that they are not at increased risk from the design and construction of this project. Additionally, it should also be noted that the MTO Environmental Protection Requirements for Transportation Planning and Highway Design, Construction, Operation and Maintenance (2010) specifically outlines provisions for highway design and construction meeting the Conservation Authorities Act for issues related to surface water, including impacts to existing water balance, protecting upstream and downstream human and non-human land and water uses, impacts to the quality of surface water and changes in erosion potential and flood risk. At this time, the provisions set forth in this guideline document have not been satisfied for this project.

Confirmation of the Role of TRCA in the 407 East Extension ProjectTRCA is respectfully requesting that the Minister of the Environment review the terms and conditions of the EA and provide clear direction as to how provincial interests related to natural hazards, natural heritage and water management are to be addressed through the MTO optimization process. TRCA is concerned that commitments made in the EA that relate to natural hazards, natural heritage and water management have not been satisfied through the detailed design stage work that is currently underway for this project. Interestingly, during the detailed design process for the 407 East Partial project, there was a similar disregard for TRCAs provincial responsibilities, and similar concerns that watershed management implications were not being addressed. At that time, TRCA requested clarification from the Minister of the Environment regarding its roles related to natural hazard, natural heritage and water management review responsibilities at the detailed design stage. In this earlier process the minister required that MTO obtain written authorization to proceed from review agencies, including TRCA. A formal review and approval process was developed and successfully followed. Provincial standards related to natural hazard, natural heritage and water management were subsequently addressed through the detailed design and construction processes.

RES.#A87/13 - FLOOD INFRASTRUCTURE STATE OF REPAIR2013 report on TRCA's flood infrastructure state of repair.

Moved by: Mike MattosSeconded by: Mujeeb Khan

THAT the Toronto and Region Conservation Authority (TRCA) Flood Management Service Flood Infrastructure State of Repair Report be updated and reported to the Authority bi-annually.

CARRIEDBACKGROUNDOne of TRCA's goals is to design, install and maintain structures that will prevent loss of life and damage to property from natural hazards such as erosion and flooding. Since Hurricane Hazel in 1954, TRCA has constructed numerous structures that help protect the public from flooding. These structures can take the form of dams, channels and dykes.

Over time, these structures degrade in ways that affect their ability to pass floods. The majority of flood protection infrastructure owned by TRCA was built between 1955 and 1970. The design life of these types of structures is typically around 50 years and some structures are in need of some major repairs to extend their functional life. The accumulation of sediment and vegetation, failed or shifted concrete panels and erosion of channel banks have reduced flood capacity for some of the channels. Some of TRCA’s dams were built more than 50 years ago and are in need of major repairs to meet current dam safety guidelines.

The highly urbanized characteristics of watersheds in the GTA require that flood protection infrastructure function in the way that they were designed. Failure of a flood protection device to perform puts property and lives at risk. On August 19, 2005 a severe thunderstorm dropped as much as 153 mm of rain in Toronto. The storm overwhelmed sewers and rivers causing flooding in many areas of the city. It is estimated by the Insurance Bureau of Canada that this storm caused $640 million in damages making it the third costliest disaster in Canadian history. This storm was a powerful reminder of the devastation flooding can cause in an urban environment.

The purpose of the Flood Infrastructure State of Repair Report is to document the current state of repair of TRCA-owned flood infrastructure and to raise awareness about the impending capital investments that will be required to maintain proper flood protection. TRCA currently owns 10 dams and 15 flood control structures (channels and other devices). The report examines each structure and categorizes them in terms of the "impact of failure" and the "probability of failure" using a risk management matrix. Each structure is assessed including its location by region or municipality and current major deficiencies.

Over the last ten years TRCA has made significant investments to remediate its inventory of flood protection structures in order to meet its obligation of protecting the GTA from flood damage. The role of the Flood Management Service, the Lakes and Rivers Improvement Act (LRIA) Dam Safety Guidelines, risk management and future capital requirements are examined in the report.

205

Flood Management ServiceIn 2009, TRCA created the Flood Management Service (FMS) within the Ecology Division. The goal of this program was to better respond to issues regarding flood warning, risk and infrastructure. TRCA combined specialties in water resources engineering, infrastructure maintenance, risk management, data acquisition and hydrometrics in order to reduce the flood risk to life and property within the TRCA jurisdiction by providing professional guidance, reliable data and support to TRCA's municipal/regional partners and the public. FMS monitors watershed conditions 24/7 and issues Flood Messages to TRCA's partners so that appropriate actions can be taken to ensure public safety. FMS also identifies areas at risk of flooding, coordinates with stakeholders to mitigate the risk, and develops outreach programs to educate the public and governmental agencies about the hazards of flooding.

A large part of FMS’s role within TRCA is to manage, monitor and maintain the various flood protection structures located throughout the GTA. FMS conducts daily, monthly and annual inspections on each structure depending on the level of risk and the technical standard of surveillance. For example, large dams with high associated risks are required to have daily, monthly and annual inspections. Small, lower risk structures such as flood protection channels may receive only an annual inspection. The results of these inspections are used to determine if the structure is performing as designed and to prioritize capital works to restore the function of the structure.

Ontario Dam Safety GuidelinesIn August 2011, the Ontario Ministry of Natural Resources (MNR) introduced the Lakes and Rivers Improvement Act Administrative Guide, Technical Bulletins and Best Management Practices Guide, also know as the Ontario Dam Safety Guidelines (ODSG). These documents are based on criteria developed by the Canadian Dam Association (CDA) and provides guidelines for the safe design, construction, management and operation of dams in Ontario. It is a resource for engineers, operators and owners to use when assessing the safety of a dam. The ODSG is not regulatory, but rather a document that defines best management practices and therefore the minimum standard of safety for dam owners. A critical component of the ODSG is the Hazard Potential Classification (HPC). The HPC determines the risk to the public if a dam were to fail. The higher the risk the more stringent the safety requirements are for a dam. Table 1 outlines the criteria for determining the HPC of dams.

Table 1 - Hazard Potential Classification

HAZARD POTENTIAL LIFE SAFETY PROPERTY LOSSES

LOW No potential loss of life. Damage not to exceed $300,000

SIGNIFICANT No potential loss of life. Damage not to exceed $3 Million

HIGH Potential loss of life of 1-10 persons.

Damages not to exceed $30 Million

VERY HIGH Potential loss of life of 11 or more persons.

Damages in excess of $30 Million

206

TRCA currently owns four dams that have HPC’s of Very High which correspond to having potential loss of life of 11 or more persons in the event of a dam failure. For example, the 2012 Dam Safety Review of G. Ross Lord Dam estimated that there would be 3,000 persons at risk and $1.3 billion in property and infrastructure damage if the dam were to fail under flood conditions.

TRCA has adopted the ODSG into its dam safety program and is in the process of upgrading each structure to meet the guidelines contained in the ODSG where possible. There are technical difficulties in bringing each structure up to meet modern design guidelines. Older dams were constructed using the engineering principles of the period in which they were built and may not meet newer requirements unless substantial investments are made. In particular, old dams that were built without any proper engineering or construction techniques may never be able to meet ODSG guidelines. In these cases options are limited to decommissioning the dam or risk management.

Risk ManagementThe Canadian Dam Association defines risk as “the consequence of an adverse event and the probability of such an event occurring”. The principles of dam safety use the concept of providing protection that is As Low As Reasonably Practicable (ALARP). It is recognized in the dam safety community that if an infinite amount of money was available, the risk around dams could be reduced to zero. For obvious reasons this is not possible. Using modern engineering techniques, however, it is possible to greatly reduce risk. The ALARP principle provides for a relatively high standard of safety by using advanced engineering and decision making tools for managing and accepting risk. When hazards are greater for a particular structure, the safety requirements are proportionately more rigorous to offset the increased risk.

TRCA recognizes the risk in owning and operating flood control structures and is constantly making improvements to reduce hazards and increase safety. In order to make improvements, the TRCA performs the following:

TRCA evaluates each structure and determines what the impacts would be if the 1.structure failed or performed below its design criteria.

The structure is inspected to identify any deficiencies that could cause the structure to 2.fail. Channels and other flood control devices can fail by erosion, overtopping and blockages. Deficiencies that can led to a dam failure are also known as “failure modes”. A failure mode is the process by which dam collapse happens. Dams have three main types of failure modes:

Overtopping - where the dam is overwhelmed by incoming flows;

Collapse - this can occur because of earthquake, overloading of the structure

due to poor design and other component failures;Internal Erosion - where embankment materials are leached from the dam

embankment in uncontrolled seepage through the structure.

3. A repair to mitigate the potential failure mode or hazard is designed and implemented when funding is available.

207

Each structure has undergone a risk assessment and is listed in Attachment 1 to help prioritize capital improvements and results are used to illustrate how flood infrastructure is ranked in terms of risk. Structures can be moved to higher risk categories within the matrix as they deteriorate or, conversely, risk is reduced as they are repaired. It should be noted, however, that there are limitations to determining risk. The complexity of forces acting on a structure is difficult to quantify and therefore determining the probability of failure is difficult. Experience, training and engineering judgment are used to assess the stability and performance of flood infrastructure.

TRCA Flood Infrastructure State of RepairThe following outlines the current “state of repair” of TRCA-owned flood infrastructure. Each structure is inspected annually and the results are examined and compiled to prioritize capital works projects. TRCA uses Hatch Energy Limited’s rating system for describing the condition of a structure. Hatch Energy is an international consulting firm that specializes in dam engineering and has been retained by TRCA for several dam safety projects. Attachment 2 summarizes the criteria for evaluating structures.

The process for evaluating structures is somewhat subjective. With the limitations of current inspection techniques it is not possible to say with certainty that a structure will or will not fail. Inspections can identify potential failure modes but the complexity of the loads and stresses placed upon structures cannot be precisely measured and so there is a degree of unpredictability in evaluating them. TRCA uses current industry standards for inspecting structures. Attachment 3 lists all flood control structures owned by TRCA and their current state of repair.

FMS has incorporated the above-noted deficiencies into its annual work plan and continually monitors each structure for issues that may alter the priority of repairs.

Current Workplan and FundingTRCA is moving forward with improving the performance and reliability of its flood infrastructure. Major capital works have been identified and engineering designs are being developed. Table 2 outlines the current funding for flood infrastructure from TRCA’s partners for 2013. These funds are used to support ongoing inspection and planning activities. Special funding requests for specific, large scale construction projects (e.g., infrastructure maintenance) will be required in the future once the appropriate studies and designs are completed.

208

* Peel Region, City of Toronto and York Region have approved enhanced budgets to meet the needs for flood infrastructure maintenance. These values are included in Table 2, above. Approximately $200,000 of the Peel Climate Change: Flood Remedial Works program budget is allocated to Flood Infrastructure. The City of Toronto contributed $200,000 from Toronto Water from an enhanced budget request for erosion and flood control infrastructure maintenance. The Region of York has contributed and additional $200,000 in 2013 to advance the work on Stouffville Channel and Dam maintenance (through the Flood Protection and Remedial Capital Works budget).

Additional Funding from the Ontario Ministry of Natural ResourcesThe Ministry of Natural Resources is assisting conservation authorities to undertake maintenance activities throughout Ontario with the Water and Erosion Control Infrastructure Program (WECI). Under this program, projects and studies undertaken on structures are eligible for 50% matching funds from the Province of Ontario. This has allowed TRCA to complete major projects such as the Yonge/York Mills Channel Maintenance Repair ($1 million total cost) and the G. Ross Lord Dam Safety Review ($150,000 total cost). The Yonge/York Mills Channel Maintenance Repair involved concrete repairs and dredging of sediment that resulted in 12 homes being removed from the regional floodplain. Numerous other smaller projects have been completed with the funds available from WECI. Unfortunately WECI funding was scaled back by 50% by the provincial government in 2012 which means fewer projects will get funding in the future.

TRCA has identified priority projects for the next five years. Some of the major projects include:Albion Hills Dam (Peel);

Black Creek/Scarlett channel maintenance (Toronto);

Stouffville Dam concrete remediation (York);

Pickering/Ajax Dyke (Durham);

G. Ross Lord Dam gate repair and generator replacement (Toronto/York); and

Secord Dam (Durham).

As annual inspections of the infrastructure take place, priorities may change based on significant negative changes to the condition of a particular structure. The ability of TRCA to respond to serious deficiencies in flood infrastructure depends on stable year-to-year funding as large capital remediation projects can take several years to complete depending on design, permits and availability of contractors. Currently TRCA receives funding for monitoring and minor maintenance but large capital repairs will be required in the future.

CONCLUSIONSTRCA’s inventory of flood infrastructure is aging and in some cases has exceeded its design life. There are a multitude of forces acting upon these structures that reduce their effectiveness in preventing flooding. Under the current funding regime, TRCA is monitoring these structures and performing capital improvements as they become necessary. However, some projects are very large in scope and require substantial funding that is not currently available. Many future projects will take multiple years to complete because of the complex engineering and design process. In the case of a dam decommissioning, public consultation and an Environmental Assessment may be required.

With the support of the Province's WECI program, several important, large scale projects have been successfully undertaken in recent years. However, this program saw major cutbacks in 2012 with the potential for even greater cuts in the future.

209

Flooding remains a serious threat to the GTA. Weather is unpredictable and extreme events can happen at any time. Climate change may increase the likelihood of such events. Extreme events combined with the dense urbanization of TRCA's watersheds increase the stresses placed upon TRCA’s flood infrastructure. To respond to this threat, TRCA must ensure that flood infrastructure is performing at the highest level of protection. Rigorous monitoring, well designed repairs and stable funding will each ensure that TRCA’s flood infrastructure will continue to minimize the possibility of catastrophic flooding in the GTA.

RES.#A88/13 - FLOOD PROTECTION AND REMEDIAL CAPITAL WORKS STRATEGYReport on risk assessment and prioritization of flood vulnerable areas within TRCA watersheds.

Moved by: Mike MattosSeconded by: Mujeeb Khan

THAT the Flood Protection and Remedial Capital Works Strategy form the basis for consultation with Toronto and Region Conservation Authority's (TRCA) local and regional municipal partners to set priorities for future flood remediation project planning and budget requests;

AND FURTHER THAT all of TRCA's municipal partners be so advised by the Flood Management Service.

CARRIEDBACKGROUNDFlood protection is an important function of TRCA. Within the last 10 years, the occurrence of several costly storms has heightened the awareness of risks associated with floods, and this has provided a renewed urgency to assess the existing flood risk within TRCA's watersheds. In 2006, the Authority authorized the development of TRCA's Flood Protection and Remedial Capital Works Study, and Philips Engineering Ltd. (now AMEC Earth and Environmental Ltd.) was retained to complete the study. This report provides a summary of their findings. The full report will be made available on the TRCA website.

1980 Flood Protection PlanIn 1980, TRCA developed a Flood Protection Plan that envisioned an integrated framework consisting of engineered flood protection works, policy tools and property acquisition to contain and manage flood risk within the flood hazard area. At the time, the Flood Control Program identified 31 flood damage centres (consisting of multiple structures in close proximity) as well as 210 less spatially extensive flood sites, based on historical flooding conditions. Since that time, TRCA has experienced continued growth with increased levels of urbanization in all of TRCA's watersheds. There have also been improvements in TRCA's ability to characterize the hydrologic and hydraulic processes operating within TRCA's watersheds, and to develop deterministic models which allow for better estimates of watershed response to rainfall. These systemic changes to watershed characteristics are a result of urbanization, as well as improvements to our tools and data. This has resulted in an expansion of the risk profile as originally determined in the 1980 Flood Protection Plan, with an increased number of flood vulnerable sites identified.

2013 Flood Protection and Remedial Capital Works StrategyTRCA has developed a Flood Protection and Remedial Capital Works Program. Works under this program include the development and updating of the Flood Protection Strategy, consultation with TRCA's local and regional municipal partners on priority areas they have identified, consultation with Planning staff on upcoming development areas, and public outreach and education about flood risks.

215

This board report speaks to the findings of the AMEC Engineering Flood Protection and Remedial Capital Works Study, which resulted in the creation of the 2013 Flood Protection Strategy. Based on the latest watershed hydrology and hydraulic studies, 42 areas with flooding risks have been identified with high concentrations of structures/roads (Attachment 1). These areas are referred to as "flood clusters" or "damage centres". The Flood Protection Strategy is intended to provide an understanding of the risk associated with each of these damage centres, to furnish a quantitative measure of the flood risk, to prioritize the damage centers according to the risk measure, and provide recommendations for flood risk remediation where possible. The Flood Protection Strategy will inform TRCA’s flood risk remediation and management initiatives, ensuring capital works funding is directed to high risk areas, as well as providing the greatest risk reduction per dollar spent.

The risk assessment at the core of the Flood Protection Strategy is based on the methodology developed for the 1980 Flood Control Plan, and uses a flood-prone site evaluation matrix that considers several factors related to:

the importance of the area to the larger community;

the flood risk and exposure associated with the site (depth, warning time, population at

risk);emergency access (human and vehicular ingress and egress, emergency access routes,

roadway design);flood damage costs (direct and indirect costs).

Each of these factors was assigned a numerical score for each site, based on a consideration of the attributes of the area, such as relation to transportation routes, type of development, population, topographic nature and river flow mechanics. Sites were numerically ranked based on their cumulative score (higher cumulative scores indicating greater associated flood risk). Attachment 2 summarizes the results of the risk assessment and prioritization for the flood clusters, and Attachment 1 provides a visual summary of the flood risk associated with each cluster. It is evident that the highest risk areas are business/industrial or mixed use locations, where the economic impact tends to elevate these areas to the top of the priority rankings. For this reason, Attachment 3 is provided where areas that are predominantly residential are ranked relative to each other.

An assessment of measures for reducing or remediating the flood risk for each of the sites was undertaken, with various measures considered with the objective of reducing flood depths, extent or impact. Among the alternatives considered were bridge and culvert upgrades, channel improvements, flood-proofing of buildings, detention or diversion of flows, and property acquisitions. Flood reduction measures were assessed as to their cost of implementation, however this assessment is of a preliminary and coarse nature due to the conceptual nature of the flood remediation measures, but is sufficient to inform the decision making process to identify priority sites for detailed study. Attachment 4 provides a visual summary of the cost of proposed remediation options for each flood cluster.

216

Flood Remediation RecommendationsThe main benefit of the Flood Protection Strategy is that it provides priority rankings of flood vulnerable areas based on current flood risk. This will allow staff to undertake long term planning and to best direct capital budgets toward remediation projects that will reduce flood risk. The Strategy is an important tool that will be shared with TRCA's municipal partners. It is expected that the Strategy will be used to frame dialogue with municipal and regional partners as well as affected stakeholders, and to provide a reference for optimizing coordination with municipal/regional or private remediation opportunities and initiatives. While the Strategy provides a "roadmap" for action, each individual flood vulnerable cluster will need to go through an Environmental Assessment prior to the implementation of any remedial options. Each year, selected projects will be highlighted in the Flood Management Service Annual Workplan.

Future ProjectsSome of the 42 potential flood remediation projects will be small in nature (e.g., a simple culvert replacement to alleviate flooding). However, the majority of the projects will be large scale construction projects involving multiple stakeholders and complex design challenges due to existing landuse and environmental and social considerations. Flood remediation projects are expected to be multi-year projects requiring significant capital investment. Partnerships with municipalities and other stakeholders will be essential for logistical reasons and to secure the required funding over several years. It is anticipated that most remediation projects will require special funding asks.

FINANCIAL DETAILSFunding for the development and implementation of the Flood Protection Strategy is provided in capital account 107-02 which receives funds from Peel, York and Toronto. In addition to remedial works, this account supports other flood management activities including outreach and education, data management and the Flood Forecasting and Warning Program.

Expected Annual Damage (EAD) is a metric used in assessing and ranking flood vulnerability. For any given year, a flood event of a specific intensity or magnitude will have an associated probability that it will occur during that year. The product of flood damage and probability of occurrence is the expected annual flood damage for that event. Where there are several events being considered of varying magnitudes, the expected annual flood damage would be the sum of the EADs for each of the events. This methodology is standard in Canada and elsewhere, and forms the basis for many flood damage assessments. (ref. to "Flood Damage Estimation Guide", Ontario MNR, April 1989, and "Expected Annual Flood Damage Computation", US Army Corp of Engineers Hydrologic Engineering Center, March 1989).

2

Direct flooding impacts consist of damage to buildings and structures due to the entry or action of floodwaters. 3

Indirect damages refer to damages due arising as a result of loss of business, closure of community facilities, and loss of income and other consequences arising from a disruption to normal life.

RES.#A89/13 - FRENCHMAN'S BAY - PICKERING ROUGE CANOE CLUB Licence Agreement Extension, CFN 26339. To extend the temporary licence agreement with the Pickering Rouge Canoe Club for the existing location on the west spit of Frenchman's Bay in the City of Pickering for three years, renewable annually, commencing November 1, 2012.

Moved by: Dave RyanSeconded by: Gloria Lindsay Luby

THAT the request to extend the temporary licence agreement with the Pickering Rouge Canoe Club for a paddling facility on Frenchman's Bay for three years, renewable annually, commencing November 1, 2012, be approved, subject to conditions satisfactory to Toronto and Region Conservation Authority (TRCA) staff and solicitor;

THAT authorized TRCA officials be directed to take whatever action is required to implement the license agreement extension, including obtaining any necessary approvals and signing and execution of documents;

AND FURTHER THAT the City of Pickering and Pickering Harbour Company be so advised by the CEO's Office.

CARRIEDBACKGROUNDSince April 1994, the Pickering Rouge Canoe Club (PRCC), formally the West Rouge Canoe Club, has operated a paddling facility on the west spit of Frenchman's Bay on lands owned by TRCA (page 5 of Attachment 1). The facility consists of two trailers on wheels for the temporary storage of canoes and kayaks, and a parking area for three to five cars. Licence agreement extensions have continued to be approved by TRCA and Pickering Council since 1995.

At Authority Meeting #6/10, held on July 23, 2010, Resolution #A129/10 was approved as follows:

THAT the request to extend the temporary licence agreement with the West Rouge Canoe Club for a paddling facility on Frenchman's Bay for three years, renewable annually, commencing November 1, 2009, be approved, subject to conditions satisfactory to Toronto and Region Conservation Authority (TRCA) staff and solicitor;

THAT authorized TRCA officials be directed to take whatever action is required to implement the license agreement extension, including obtaining any necessary approvals and signing and execution of documents;

AND FURTHER THAT the City of Pickering and Pickering Harbour Company be so advised by the CAO's Office.

On September 11, 2012, TRCA received a request from the Pickering Rouge Canoe Club to extend this temporary licence agreement for the next three years. December 20, 2012, TRCA notified City of Pickering of the lease extension request. On May 6, 2013, at the Planning and Development Committee, the City of Pickering staff report (Report PLN08-13) was recommended for approval at City of Pickering Council Meeting to be held on May 21, 2013 (Attachment 1).

223

RATIONALEFurther to the updated Frenchman's Bay Waterfront Master Plan (2012), the paddling activity is consistent with appropriate water-based recreational activities on the Bay. The Master Plan identifies the location of a permanent PRCC facility approximately 250 metres west of the current temporary location. The new facility would support boat launches, floating docks, public washrooms, equipment storage and change rooms. The location of the temporary paddling facility does not interfere with the ongoing harbour entrance reconstruction project or the implementation of the proposed Frenchman's Bay Waterfront Master Plan. Until a permanent facility can be established, the licence agreement provides recreational water-based programming by the Pickering Rouge Canoe Club without disruption to its members.

Pickering Harbour company will be notified of the licence agreement extension as owners of the abutting bed of Frenchman's Bay. Staff, upon approval by the Authority, will prepare and execute the necessary documents for extension of the licence agreement on an annual basis, commencing with the period November 1, 2012 to October 31, 2013.

FINANCIAL DETAILSPickering Rouge Canoe Club will pay a rental rate of $500 for the first year of this extension and for the remaining two years of the extension the rental rate will be adjusted to $750 per year. PRCC will continue to cover the costs of one portable toilet within the licence area, for the use of club members, and any additional costs deemed appropriate to cover TRCA property taxes for the site area.

RES.#A90/13 - BLACK CREEK PIONEER VILLAGE ARTIFACTSDeaccession. Deaccession of 35 artifacts that are superfluous to the needs of Black Creek Pioneer Village.

Moved by: Dave RyanSeconded by: Gloria Lindsay Luby

THAT Toronto and Region Conservation Authority (TRCA) staff be authorized to deaccession two agricultural tools - a barley fork and a seed-sowing basket, that have been on long-term loan to the Peel Art Gallery, Museum, and Archives since 1968;

THAT staff be authorized to deaccession one item, a piano, to a more appropriate institution;

AND FURTHER THAT staff be authorized to deaccession by auction:9 beds or parts hereof2 bookcases1 cabinet2 chests of drawers1 cradle6 cupboards3 desks1 bench1 shelf3 sideboards2 tables1 wash-hand stand.

CARRIEDBACKGROUNDAt Authority Meeting #3/01, held on April 27, 2001, Resolution #A53/01 approved Black Creek Pioneer Village (BCPV) Collections Policy which contains policy for deaccessioning, which is the formal process of removing accessioned artifacts from the permanent collection.

The Collections Policy specifies the scope and extent of collections; selection criteria for artifacts; and the methods by which artifacts will be acquired, lent and borrowed; and provides the authority to dispose of artifacts in accordance with ethical museum practice. The Collections Policy enables Black Creek Pioneer Village to collect selectively and to deaccession where deemed necessary. The policies and procedures for this deaccessioning are those followed by professional museum associations and peer institutions and direct that proceeds from the sale of deaccessioned objects should be used in collections management.

Black Creek Pioneer Village collections have been acquired since 1954 as the Village has evolved. Lack of sufficient storage space has been a major problem for more than four decades. The addition of the storage facility in the Visitors' Centre in 1985 provided some badly needed “clean” storage for the most fragile artifacts, but did not relieve the severe need for storage for a lot of the collection, particularly large items, which are still housed in unheated barns and wet basements.

232

Since 1985, staff has severely limited active collecting. Staff efforts have been redirected to assessment of the condition and scope of the current collection. Through this effort staff is gradually identifying artifacts that clearly do not fit within the established criteria of the Collections Policy or are multiple duplicates. In these cases, deaccessioning according to accepted museum practice is considered the most effective use of limited resources, while at the same time ensuring that the reputation of TRCA and Black Creek Pioneer Village are not harmed.

RATIONALEArtifacts on Long-Term Loan to other Institutions:BCPV has had two 19th century wooden agricultural tools, a barley fork and a seed-sowing basket, on continuous loan to the Peel Art Gallery, Museum, and Archives (formerly the Peel Museum and Art Gallery) since 1968 (the barley fork is used for stacking grain once harvested; the basket, for holding seeds when being planted). For this entire period, BCPV has never had need to recall either of these items for its own use. A request has been received from the Peel Art Gallery, Museum, and Archives (solicited) to transfer ownership from TRCA to the body currently displaying and using these artifacts. Doing so would permanently transfer ownership of these artifacts to an institution that is actively exhibiting these items; weed from BCPV's own collection duplicate artifacts; and free BCPV staff from expending resources to inspect and inventory these artifacts periodically, renew loan agreements, and manage the relevant records, an on-going task.

Artifact to be deaccessioned to a more appropriate institution:In 1983 Black Creek Pioneer Village acquired an upright piano, manufactured by the Dominion Organ and Piano Company of Bowmanville, ON, and dating to 1902+-1904 (bears a patent date of 1902 08 23). Since 1988, this piano has been on display in the Canada West Room of the Visitors' Centre at the Village. Recently, the Food Services section requested that the piano be removed in order to give more flexibility in meeting the diverse needs of clients. That the Village has no space in which to store this piano and that the piano post-dates the restoration date of the Village by thirty-five years necessitates staff's requesting authorization to deaccession this piano to another institution. The Canadian Piano Museum, in Napanee, Ontario, has requested that this piano be deaccessioned to them, and staff so recommends.

Items to be Deaccessioned by Auction:With the aid of experts knowledgeable in the assessment and dating of furniture, BCPV has been cataloguing and dating items in storage with a view to identifying objects that are late to the collecting period of the Village, are in such poor condition that they could not be exhibited and are in a condition that is beyond the financial resources of the Village to have repaired, or are additional duplicates to ones of which the Village already has many examples. It is the intention of this on-going work to submit periodically lists of such pieces to the Authority for permission to deaccession. This latest submission consists of:

9 beds, or parts thereof. Four beds are incomplete (i.e., missing major parts); one has

been altered. Moreover, all bedrooms in Village buildings are already furnished with beds;

2 bookcases. One bookcase is missing its bottom half; the other is late (ca 1900);

1 cabinet. Back is badly warped. The use of plywood in its construction indicates a 20th

century date;

233

2 chests of drawers. One is in poor condition; the other is late. Black Creek has many

chests of drawers in its collection;1 cradle. Late (donor dates to after 1887). Black Creek has a number of cradles in its

collection;6 cupboards. All are in damaged condition. Moreover, one cupboard is very large (7' h. x

6' wide), too large for most of the restored rooms in the Village;3 desks. One has been cut down; one is missing its drawer; the other is late;

1 settle (bench). Condition: separated into two parts; missing hardware; original finish,

stripped. – Duplicates: others, in better condition, in the collection;1 shelf bracket. Late (1890s to 1910s);

3 sideboards. Two are in poor condition (would require refinishing to make displayable);

the other, is too large for exhibit in most restored rooms in the Village. – Duplicates: others, in better condition, in the collection;

2 tables. One would require complete refinishing for its use; other, is late (1890s to W.W.

I). – Duplicates: the Village has many tables in its collection (> 100);1 wash-hand stand. Condition: loose boards; original finish has been removed.

FINANCIAL DETAILSArtifacts on Long-Term Loan to other Institutions:No financial compensation will be received for the transfer of these two items; TRCA, however, will benefit financially in that staff costs for periodically checking on these pieces will no longer be incurred.

Artifact to be deaccessioned to a more appropriate institution:TRCA will not receive any compensation for the transfer of this piano; the Canadian Piano Museum will, however, cover the costs of transportation of the piano from the Village to Napanee, estimated to be about $500.00.

Items to be Deaccessioned by Auction:Staff recommend that these 32 pieces be deaccessioned by auction through auction firms. Doing so, particularly in the case of the larger pieces of furniture, will free urgently needed storage space. Museums generally deaccession through auction, with all proceeds going back into the collections program. Consistent with BCPV's Collections Policy, all proceeds from the deaccessioning of these 32 items will be applied towards collections care and restoration. Priorities in this area are: 1) the purchase a chest freezer for the eradication of insect pests in in-coming textile pieces as they come into the collection; 2) improvements to the Gallery exhibit space in the Visitors’ Centre; 3) the contracting of a textile consultant to catalogue in detail the Village's woven coverlet collection.

Moved by: Jack HeathSeconded by: Chris Fonseca

THAT Greening Your Grounds - A Homeowners Guide to Stormwater Landscaping Projects be received.

CARRIEDBACKGROUNDIn November of 2009, Toronto and Region Conservation Authority (TRCA) staff along with the City of Brampton, the Community Environment Alliance and the Brampton Horticultural Association submitted a collaborative funding proposal to the Ontario Trillium Foundation (OTF). This funding would allow the collaborative partners to plan and implement a four year environmental project to raise the awareness of stormwater management within the Valleybrook community.

236

Valleybrook is a densely populated community between Sandalwood and Williams Parkway in Brampton. It houses the main artery of the Etobicoke Creek, spans approximately four kilometres, and provides water outfall (stormwater discharge into the creek) for over 8,000 residences. Each spring, the corridor is subject to extreme flooding from heavy rainfall and spring melt. One of the factors adding to the extreme flooding events is the large amount of water outfall from the residential properties in the area. Due to the landscaping, positioning of eaves troughs, and hard driveway surfaces, most of the heavy rainfall and spring melt is running over these properties, into the storm drains and directly into the Etobicoke Creek. Not only is this exacerbating the flooding issue, it is also polluting and eroding the creek.

In March of 2010, the funding application to the Ontario Trillium Foundation was for approved for $238,600 over four years. The first two years of the project (2010 and 2011) focused on getting to know the community by inviting them out to the public spaces in Valleybrook for tree planting, nature walks, litter clean-ups, healthy yards workshops and TRCA's Yellow Fish Road storm drain marking program.

Through participant feedback received during the first two years of activities, TRCA staff confirmed that the two biggest barriers to residents collecting and/or reusing rainwater on their property were the knowledge and the cost. In the third year of the project (2012) TRCA staff developed “Greening Your Grounds – A Homeowners Guide to Stormwater Landscaping Projects". The 55 page guide enables staff to address the knowledge barrier and to work with the community members to rethink and rework the landscapes on their properties. TRCA staff applied for funding to assist landowners with the costs of implementing projects from the guide. In 2012, TRCA received $22,000 through the Ministry of the Environment, Canada-Ontario Agreement (COA). This funding allowed TRCA to develop a “Water Garden Grant” program to offer technical and financial assistance to residents within the Valleybrook neighbourhood. Staff held a focus group session with residents to develop the program and promoted it through the door-to-door delivery of a promotional brochure.

Greening Your Grounds – A Homeowners Guide to Stormwater Landscaping Projects was introduced to the Brampton community through six workshops in the spring of 2013. The workshops were designed as a series and enabled the residents to work through the process as outlined in the guide. The final workshop provided the opportunity to have a one-on-one consultation with landscapers, engineers and gardening experts. A total of 230 participants attended the workshops and over 80% of the participants attended multiple workshops. A total of 26 rain barrels were donated to homeowners along the Etobicoke Creek to help reuse 1430 gallons of rain water.

The guide was presented at the TRCA Management Team meeting held in March. A number of TRCA staff expressed an interest in the document and identified that other conservation authorities, municipalities and industry representatives would potentially be interested in utilizing it as well. TRCA staff would like to accommodate a broad distribution of this resource and are exploring options for a web based and a print on demand method to do so. Copies will be made available for Authority Members at the May 24th meeting.The forth and final year of the Ontario Trillium Funding is underway and will commence with a final report in June of 2014. Deliverables for the 4

th

year include the continuation of community events on public lands and engaging schools in school ground greening projects. TRCA will continue to promote and distribute the Greening Your Grounds workbooks and have applied for additional funding to expand the Garden Grant program.

237

FINANCIAL DETAILSThe writing and design of the Greening Your Grounds workbook was an in kind contribution of the TRCA Stewardship staff and Marketing and Communications staff. The Ontario Trillium Foundation allocated their funding towards the printing of the guide and the associated workshop and administration costs.

RES.#A95/13 - FLOOD MANAGEMENT SERVICE2012 Annual Report and 2013 Workplan. Annual update on the status of the Toronto and Region Conservation Authority Flood Management Service and highlights of current initiatives.

Moved by: Mike MattosSeconded by: Mujeeb Khan

THAT the Flood Management Service (FMS) 2012 Annual Report and 2013 Workplan be received.

CARRIEDBACKGROUNDHighlights of the 2012 Annual Report and 2013 Work Plan2012 marked the second year of the Flood Management Service's existence, with the Flood Infrastructure, Hydrometrics, Data Management and Flood Risk Management groups under one program within the Ecology Division. In 2011 the FMS focused primarily on strategic planning. However, 2012 saw the initiation of many projects that position Toronto and Region Conservation Authority (TRCA) for long term sustainability in flood management, as well as the completion of several important projects.

The following provides highlights of TRCA's work in 2012 which is provided in more detail in Attachment 1, along with goals for the Flood Management Service for 2013. Attachment 2 speaks specifically to the components of the Flood Forecasting and Warning Program (which is part of Flood Risk Management) and how they meet the requirements presented in the "Provincial Flood Forecasting and Warning Implementation Guidelines", Ministry of Natural Resources, August 2008. The GTA Flood Standards were adopted at Authority Meeting #5/03, held on June 27, 2003, by Resolution #A130/03. These standards were later adopted by the Province. The delivery of the Flood Forecasting and Warning Program is carried out in accordance with achieving the goals of the Natural Hazards Policies of the Provincial Policy Statement, section 3.1 of the Planning Act.

238

In 2012, a number of significant goals were realized and are highlighted below:After two relatively quiet years in 2010 and 2011, the weather of 2012 tested critical 1.elements of TRCA’s Flood Forecasting and Warning Program. TRCA issued 13 Flood Messages in total: three Water Safety Messages, six Flood Outlook Statements, two Flood Watches and two Flood Warnings. One of the success stories coming out of 2012 is the effective partnership that has been developed between TRCA and Toronto Transportation. Through improved communications, understanding of each other's program operations, and collaboration on a "dashboard" to display flood information in real-time within the Transportation's Command Centre, the agencies were able to successfully manage flooding on the Bayview Extension and the Don Valley Parkway during several events in July and September.After several years of development, the TRCA Flood Protection and Remedial Capital Works 2.Strategy was completed. The Strategy provides a roadmap for TRCA to undertake projects to reduce risk to life and property by identifying and prioritizing areas of high flood risk. The Strategy also provides guidance on potential remediation options. A separate report that provides more details on the Strategy is included in this month's agenda as an information item.The Flood Infrastructure team produced a "Flood Infrastructure State of Repair" report that is 3.also included as a separate item on the agenda. This marks an important first step toward creating a long-term capital asset management plan for TRCA's flood control infrastructure. The report identifies the risks associated with each structure, its current condition and future maintenance/program requirements. Two major flood maintenance projects were completed: 1) Stouffville Channel clean-out and 4.2) Phase 3 of the Yonge York Mills Channel clean-out (the latter was partially funded under the Ministry of Natural Resources Water and Erosion Control Infrastructure program).Staff completed a transition plan that has allowed FMS to begin maintaining and operating 5.TRCA's hydrometrics (gauging) network internally, bringing technical expertise in-house. This, along with the purchase of new state of the art monitoring equipment, has allowed for increased efficiency in terms of cost and in time. Data management activities included the completion of the daily forecasting module of the 6.Flood Event Documentation Database. In partnership with other GTA CAs, additional modules are currently under development. In addition, historical hydrometric data is now published to a web portal allowing for easy searching and sharing of volumes of data that was previously difficult to access.As part of TRCA's ongoing emergency management training, the Risk Management team 7.conducted hands on drills with staff to test preparedness. Staff also assisted municipal partners (York Region, City of Toronto) with the planning and implementation of their annual emergency exercises as required under the Emergency Measures Act. TRCA was asked to participate in the City of Toronto's Office of Emergency Management training program as a regular trainer for City staff. In 2012, staff participated in Emergency Preparedness Week events in both the City of Mississauga and York Region.A consultant was hired to advance the work on the Downtown Brampton Flood Protection 8.Feasibility Study. This work is one project that forms part of the Downtown Brampton Etobicoke Creek Revitalization Study (the other project is the Urban Design and Landuse Study led by the City). At the end of 2012, Task 2 was completed (of four tasks). The anticipated project completion date is fall 2013. In addition, this work will form a key component of Brampton's Comprehensive Special Policy Area Update, as part of Brampton's Official Plan and Growth Management Review.

239

Major goals for 2013 include:Continued advancement of flood forecasting and warning tools, and enhancements to the 1.flood warning operations (flood duty officer activities).Major repairs to G. Ross Lord Dam (including replacement of the generator and gate motor 2.upgrades) and Claireville Dam (replacement of windows and diesel tanks).Albion Hills Dam and Stouffville Dam studies to be completed and recommendations to be 3.initiated.Expansion of the real-time all season precipitation gauge network (in Richmond Hill, 4.Caledon and Pickering).Improvements to data management systems to include: incorporation of Aquarius software 5.into data management programming, establish disaster recovery plans for flood warning/monitoring systems.Staff to represent TRCA and the GTA Flood Forecasting and Warning Group on the 6.Provincial Flood Forecasting and Warning Committee.Hold the 5th annual "Floods Happen" Workshop to inform municipal partners about flood 7.forecasting and warning operations and to strengthen partnerships.Complete the Downtown Brampton Flood Protection Feasibility Study.8.Continue work to support municipal Special Policy Area (SPA) amendments through the 9.development of flood mitigation projects as required (e.g., Caledon, Richmond Hill, Mississauga, Markham).Extend knowledge of emergency management procedures to other departments within 10.TRCA by assisting with the development of emergency preparedness plans for TRCA facilities.Implement the recommendations of the Flood Protection Strategy and the Flood 11.Infrastructure State of Repair reports.

Quick 2012 Weather Facts and the Impacts of "Superstorm Sandy"As mentioned above, 2012 brought a few weather events that had flooding implications within TRCA's jurisdiction, summarized as follows:

The winter of 2012 was very mild and dry, with little snow accumulation and a minimal

spring freshet.Precipitation amounts were very low from February to May, reaching as low as 32% of

normal amounts in the month of March.June, July, September and October recorded above average rainfall amounts (ranging from

3% to 97% higher than normal amounts). However, this was mainly due to numerous large thunderstorms that brought short duration and high intensity rainfalls to the jurisdiction.November was unusually dry and only received 10 mm of rainfall for the entire month at

Toronto Pearson Airport (only 15% of normal amounts and the driest month of the year).

240

During the last few days of October 2012, Hurricane Sandy was setting up to be similar to Hurricane Hazel in 1954. The storms tracks were eerily similar, as was the fact that a secondary storm was forecasted for the area due to a low pressure system over the region on the weekend. Fortunately, southern Ontario received much less rainfall than originally anticipated. For comparison, Hurricane Hazel released 285 mm of rain over 48 hours (with the majority of rain falling within 12 hours). Hurricane Sandy, was downgraded to a post tropical depression (a "Superstorm"), and by Sunday evening (October 28th) it was not expected to release more than 100 mm (maximum) in our area over 3-4 days. This amount of rainfall over a long period of time does not typically pose a threat of flooding in the TRCA jurisdiction. However, given the saturated ground conditions and the potential for thunderstorm activity, TRCA did issue Flood Messages during the event.

Superstorm Sandy hit land on the afternoon of October 29th, covering 4.7 million square

kilometres (with a 1,600 km diameter, stretching from the eastern seaboard to northeastern Ontario).Sandy brought multiple weather elements including wind, rain, surge and snow (4.2 m wave

surges were recorded in New York City).Estimated damages were over $50 billion.

Southern Ontario experienced wind gusts from 80-90 km/hr (strongest winds in Sarnia of up

to 100 km/hr).Two fatalities were attributed to the strong winds in Ontario.

Many agencies, including TRCA opened their emergency operations centres.

TRCA received numerous media requests for information and interviews (for print, television

and radio, including CBC Radio's Metro Morning).

Overall, Sandy did not result in flooding issues within TRCA's jurisdiction. However, it served as an extremely valuable test for the FMS communications and operations procedures. Several deficiencies in TRCA's Emergency Operations Centre were identified that will be addressed in 2013 through a re-organization of workspace and upgrades to equipment. TRCA staff also learned that the "no news is good news" approach does not apply to communications with media, and that we need to ensure that TRCA has capacity to deal with a barrage of media inquiries even when we do not necessarily have local flood concerns. These items are addressed in the 2013 workplan (Attachment 2).

Future Work for the Flood Management Service (2014 and Beyond)The Provincial Flood Forecasting and Warning Implementation Guidelines (Ministry of Natural Resources, August 2008) provides a framework for the typical activities that the Flood Management Service should undertake to achieve the goal of minimizing risks to life and property due to flooding. Although this report speaks primarily to the results achieved in 2012 and the workplan for 2013, planning for future years has already begun. In addition to ensuring TRCA follows the best practices outlined in the Provincial Guidelines, the FMS will also be following the roadmaps laid out in two additional reports presented to the Authority: 1) Flood Infrastructure State of Repair and 2) Flood Protection and Remedial Capital Works Strategy. Future workplans will build upon the direction of these two studies.

241

Currently, FMS receives adequate funding to manage all programs through annual budget requests. With this level of funding routine maintenance activities on flood control structures are being completed, as well as studies to understand flood risks and to develop plans to mitigate the risks. However, over the next few years as recommendations from the State of Repair and Flood Protection Strategy are undertaken, more funds will be required. These works would no longer fall under "routine maintenance" but could be likened to "major renovations" or "construction of new infrastructure". They would be large scale projects (e.g., modifying or repairing concrete lined channels, major repairs to dam gates/buildings, floodproofing structures, removal of dams, etc.) and it is anticipated that several funding avenues will need to be pursued, including provincial and/or federal assistance (in some cases) and special budget requests to local municipalities and regions.

FINANCIAL DETAILSFunds have been identified in the 2013 Operating Budget from TRCA's municipal funding partners (account 115-60 and 108-01) for general program operations. Municipal capital funds for 2013 are identified within the Toronto, Peel, York and Durham budgets to undertake the project activities identified in the 2013 work plan.
