7 1. Introduction 1.1 Content of this Asset Management Plan This document forms Appendix A of the City of Barrie s Asset Management Plan (AM Plan) and addresses the City s Right of Way Assets only. Assets included in this AM Plan are: Solid Waste Assets Storm Facilities Storm Linear Wastewater Facilities Wastewater Linear Water Facilities Water Linear. The body of the AM Plan details the approach and methodology taken in determining the framework for the AM Plan and discusses results at the corporate level. Each Appendix to the main report describes specific results from a study of each asset service area including Environmental (Appendix A), Transportation (Appendix B), Recreation and Culture (Appendix C), Facilities (Appendix D), and Fleet (Appendix E). Note that environmental related facility and fleet assets are included in Appendices D and E respectively. 1.2 Purpose of this Asset Management Plan This AM Plan is intended to improve the City of Barrie s ability to achieve its corporate goals and objectives in a way that best services its customers. It provides a rational framework that enables systematic and repeatable processes to manage costs, risks and levels of service for the City s asset portfolio. The AM Plan identifies expected future costs and assists in predicting future barriers to efficient and effective service delivery. With this understanding, the City s asset managers and operators will be better equipped to remove physical, financial and political barriers before they negatively impact customer levels of service. This is the second set of AM Plans for the City of Barrie. Additional data has been amended to the original set of plans which improves the confidence in the results. It is intended that the continual improvement of asset management practices within the City of Barrie will result in further updates to this document. As such, this AM Plan is a living document that will require ongoing refinement to reflect the evolution of asset management maturity within the City of Barrie over time. 1.3 Relationship to Other City Documents/Outputs The relationship of this AM Plan to other City Documents and planning outputs is illustrated in the figure below. The AM Plan is the base framework (tool) to assist the City in developing appropriate direction and inputs to budget forecasts, master plans, and associated studies/outputs.

9 2. Asset Portfolio 2.1 Overview of Environmental Service Delivery The City of Barrie is responsible for a broad portfolio of assets that support goals of environmental services delivery. These goals include: Water and Wastewater To ensure that adequate water supply and treatment and sewage collection and treatment are provided to the residents of the City. To ensure that development within the City is serviced by municipal sanitary sewers and municipal water. To ensure that the expansion of urban services and development extends in a contiguous pattern from the established service system. To ensure that servicing of development shall employ best management practices to ensure sensitivity to the natural environment and efficiency of City services and operations. To minimize any negative impact that a public utility may have on the natural environment and cultural heritage resources. To maintain a high standard of water quality in Kempenfelt Bay and in the numerous watercourses within the City. To provide safe, sanitary, environmentally sound and efficient methods of water treatment and distribution and sanitary sewage collection and treatment for residents, businesses, institutions and industries. To encourage measures which promote the conservation of water through appropriate engineering and building requirements. Environmental Protection To ensure the health and safety of area residents and prevent the loss of life and minimize property damage due to flooding, erosion, steep slopes and unstable soils. To protect, preserve and enhance land with environmentally significant natural features and ecological functions and to maintain and improve where possible the diversity of natural features or the ecological functions for which an area is identified. To maintain Environmental Protection Areas as viable and natural ecosystems through the protection of the wildlife and aquatic habitats, the maintenance of the flood control and storage capacities of the flood plain and the enhancement of the water quality and the natural water filtration capability of the system. To protect and enhance the water quality and environmental, aesthetic and recreational potential of the City's watercourses, Little Lake and Kempenfelt Bay. GHD City of Barrie AM Plan Appendix A: Environmental 4

10 To encourage effective stormwater management in order to control flooding, erosion, sedimentation and maintain and enhance water quality in the receiving watercourses and water bodies. To promote the incorporation of natural waterways, valleys and ponds into continuous green corridors for wildlife habitat, open space, and parkland. To ensure stormwater management practices minimize stormwater peak flows and contaminant loads, and maintain or increase the extent of vegetative and pervious surfaces. Waste Management To provide facilities for the clean, safe, economic and efficient disposal and/or recycling of waste. To provide for the safe and compatible development of lands adjacent to the Waste Management Facility. To ensure that the City is continually provided with landfill facilities by pursuing long-term plans for the location and development of alternative sites and the efficient reduction of unnecessary or nonrecyclable waste. 2.2 Hierarchy of Assets Asset information is needed to support decision-making. The asset hierarchy provides the framework for segmenting the City asset portfolio into appropriate classifications and describing the linkages. The asset hierarchy used for this AMP is shown below. Table 2-1 Asset Hierarchy Environmental Services Level 1 Level 2 Level 3 Storm Facilities Mechanical Devices Storm Facilities Natural Ponds Watershed Storm Facilities Storm Detention Ponds Watershed Storm Linear Culverts Watershed, Size, Material Storm Linear Storm Sewers Type, Size, Material Wastewater Facilities ORO Bio-Solids Facility Process Area, Component Wastewater Facilities SPS Component Wastewater Facilities WPCC Process Area, Component Wastewater Linear Sanitary Sewers Type, Size, Material Water Facilities Booster Stations Component Water Facilities SWTP Process Area, Component Water Facilities Underground Reservoirs Component Water Facilities Water Towers Component Water Facilities WPS & Wells Component GHD City of Barrie AM Plan Appendix A: Environmental 5

The following figure outlines the replacement value of the City s environmental asset portfolio, in 2011$. Figure 2-1 Environmental Assets Costs, 2011$ GHD City of Barrie AM Plan Appendix A: Environmental 6

12 2.4 Installation Profile of Assets To assist the City with future funding needs analysis, it is helpful to understand the installation profile of the asset profile portfolio. The following graphs show the replacement value of the assets by year of installation, in 2011$. The story these graphs tell is that the majority of City assets were installed between 1980 and Within this timeframe, the graphs show two main periods of growth, at which a significant number and value of assets were installed. The first being in the mid to late 1980 s, and the second being from 1995 to Please note a significant change from the 2009 AMP; portion of most Environmental Facilities has been moved to Corporate Facilities. This can most notably be seen in reviewing the WPCC assets installed in 1989 which are now incorporated instead with Corporate Facilities management.

This program requires municipalities to provide information on how the municipality conducted business and provided services in the previous year by September 30, based on key factors and indicators. Some of these measures can be compared between municipalities and serve as benchmarks for local governments to strive to deliver more efficient and effective services to their property owners and residents. Both effectiveness and efficiency measures are needed to properly assess service delivery. Without effectiveness measures, the least cost form of service delivery would be perceived as optimal because it would yield the lowest cost per unit of delivery. With effectiveness measures, other factors are evaluated, such as how well services meet municipal service goals and the expectations of the public. The MPMP measures, objectives and indicators related to water and wastewater services are provided in Table 3-2 below. Table 3-2 MPMP Measures Environmental Measure Objective Type Indicator Drinking Water Drinking water treatment Drinking water distribution Efficient municipal water treatment services Efficient municipal water distribution services Efficiency Efficiency Operating costs for the treatment of drinking water per megalitre Operating costs for the distribution of drinking water per kilometre of water distribution pipe GHD City of Barrie AM Plan Appendix A: Environmental 16

This initiative is led by the Chief Administrative Officers (CAOs) and City Managers in each participating municipality. OMBI is intended to foster a culture of service excellence in municipal government by creating new ways to measure, share GHD City of Barrie AM Plan Appendix A: Environmental 17

23 and compare performance statistics and allow experts in participating municipalities to share ideas on operational practices. The City of Barrie recently joined the OMBI initiative.

25 4. Growth & Demand The City of Barrie expects to enter a period growth over the coming years with the addition of annexed lands to the south of the City and new employment lands coupled with a prioritized expansion of transit options. This section documents how the City of Barrie is working towards understanding and preparing for this coming period of growth. This includes: Future Levels of Service Corporate References and Studies Projected Future Demand Factors Influencing Demand Projected Growth and Demand on Services Impact of Changes in Demand of Asset Utilization. 4.1 Future Levels of Service Future demand forecasts are essential if the future impact on existing assets is to be appreciated. An understanding of future levels of service develops a foundation to base the need for future investment. Changes to current levels of service need to be identified, and considered and approved by City Council before they are implemented. This business process is described in more detail within the parent document which outlines the corporate asset management policy and framework for the City of Barrie. The discussion with the City Council should be a balanced trade-off discussion between: Levels of service The cost of that service, customers willingness to pay and the budgets necessary to meet the service levels The inherent risk profile in the infrastructure program related to delivering the agreed level of service and the budget provided. Water and Wastewater Assets It is anticipated that future levels of service necessitated by growth within the City can be adequately met due to the construction of the new surface water treatment plant (due for completion in 2011) and the recent expansion of the existing WPCC facility. These capital improvements, coupled with existing water and wastewater infrastructure, will meet foreseeable future levels of service within the City of Barrie. Other Environmental Assets At this point in time, no future levels of service are anticipated for other environmental assets such as stormwater facilities and solid waste facilities. Future levels of services for environmental assets will be continually assessed. The quantity of levels of service to be provided will however, increase with the growth of the City. GHD City of Barrie AM Plan Appendix A: Environmental 20

26 4.2 Corporate References and City Studies; Future Demand for Environmental Services The future demand for environmental services has been defined in various studies commissioned by the City of Barrie over the last 20 years. This is particularly evident for drainage and sanitary assets. Studies and master plans completed by the City relevant to environmental services are as follows. Barrie South Sanitary Master Plan, prepared by Aecom Canada Ltd, August 2009; Update of the Existing City of Barrie Water Model Study Report. Aecom Canada Ltd Industrial Sanitary Drainage Area Master Plan, prepared by Skelton Brumwell and Associates Inc, revised February 2006; Kidd s Creek Master Drainage Plan Class Environmental Assessment, prepared by the City of Barrie Engineering Department, January 2005; Master Drainage Plan, Municipal Class Environmental Assessments, Dyments Creek, prepared by Jones Consulting Group Ltd, June 2004; Sophia Creek Watershed Master Drainage Plan, prepared by Skelton Brumwell and Associates Inc, February 2002; Hotchkiss Creek Master Drainage Plan Update Environmental Assessment Document, prepared by RG Robinson and Associates, April 2000; Lovers Creek and Hewitts Creek Master Watershed Plans, prepared by Cumming Cockburn Limited, December 1995; North Sanitary Drainage Area Master Plan, prepared by Skelton Brumwell and Associates Inc, April 1995; Lakeshore Sanitary Drainage Plan Master Plan, prepared by Skelton Brumwell and Associates Inc, February 1990; and Cundles Sanitary Drainage Area Master Plan, prepared by Skelton Brumwell and Associates Inc, February South Sanitary Drainage Area The most recent of these plans, prepared by Aecom in August 2009 outlines recommended alternatives for an implementation strategy for the South Sanitary Drainage Area. These recommendations should be considered in future growth plans of the City. The recommendations are as follows. Alternative 2C (highest priority) Implement the Essa Road Sewershed source control investigation study at an estimated cost of approximately $200,000 Alternative 2A Implement Essa Road Sewershed conveyance improvements at an estimated cost of $1,430,000 Alternative 3 Implement Paddison Farms Sewershed conveyance improvements at an estimated implementation cost of $1,420,000 GHD City of Barrie AM Plan Appendix A: Environmental 21

27 Hydraulic Model Update Study Recommendations The City Hydraulic Model Update Study Report, completed by Aecom, outlines many recommendations, some of which relate to future growth and demand of water assets. Recommendations/conclusions relating to growth and demand from this study are as follows. Several areas are being considered for future commercial land use. Fire flow requirements cannot be met with the current infrastructure demands. It is recommended that infrastructure upgrades be planned to overcome these problems. If pressure zones are treated as independent zones, with no interaction, there is a deficit of storage in zones 3S and 2N. It is recommended the City collect power monitoring data for facilities to be able to update and use the energy model successfully within InfoWater. This could assist in forecasting energy usage of the future growth of the City. Fire flow analysis shows deficiencies in meeting fire flow requirements with respect to the City s fire flow criteria. Several areas exhibit insufficient capacity to carry fire flows due to small diameter mains, dead end mains and high elevation areas. Local systems should be reviewed and augmented appropriately. Intensification Study In April 2009, the City of Barrie s Planning Services Department completed an intensification study as part of the City s overall growth management plan. The intent of the study was to define: A long term vision and establish specific principles to guide future decisions on development; Asses the City s capacity to meet the intensification targets established through the Provincial growth plan; and To recommend policies and performance standards for the Official Plan and Zoning By-law. With regards to the environmental services, the intensification study has made the following statements in terms of growth and demand specific to sanitary, water and storm assets. Only those works identified in the 2011 capital program have been included in the forecasts in this AM Plan. 4.3 Projected Future Demand For the purpose of this AM Plan it has been assumed the growth of Environmental Services asset portfolio is commensurate with the City s population growth, with the exception of water and wastewater facilities, which are assumed to be at build out once the work in progress is complete. Which requirements and recommendations from the afore referenced plans have the best value for meeting future levels of service is somewhat ambiguous due to the age of some documents. As such, specific future demands for the environmental services asset portfolio should be addressed in an updated master plan and study. Near term capital improvements to cater for future demands are discussed below with assumptions applying to all assets relating to: Water linear; Wastewater facilities; GHD City of Barrie AM Plan Appendix A: Environmental 22

28 Wastewater linear; Storm drainage facilities; Storm drainage linear; and Solid waste facilities. Sanitary: The City Water Pollution Control Centre (WPCC) has been planned and designed to accommodate a maximum population of 175,000. To accommodate additional population, the WPCC will likely require membrane filter technology at the outlet to meet maximum daily phosphorous limits of 3.1 tonnes recently imposed by the Ministry of the Environment. Alternatively, further reduction in per capita water used throughout the City would need to be realized, however, the City of Barrie already has a low per capita water consumption compared to other municipalities. Additional modelling would be needed to identify required local sewer improvements specific to each intensification study. Water: The City water system has also been planned and designed on the basis of a maximum population of 160,000. Additional population will require expansion of the Surface Water Treatment Facility. The City s water model needs to be run to identify required local water main improvements specific to each intensification area. Storm: There are several intensification areas that are regulated by the Lake Simcoe Region Conservation Authority as well as the Nottawasaga Valley Conservation Authority that will limit developable area and may limit required servicing works. Storm drainage would require local sewer system upgrades associated with additional road surface widths. The increase in asphalt surface would increase the need for additional storm water quality measures including pond retro fits and larger oil grit separator structures. Intensification would require storm water runoff controls that limit peak flows to existing conditions. Yonge Street Nodes and Corridors Sanitary: As the trunk sanitary sewers are not located along the corridor or intersecting arterial roads, local sanitary sewers that convey the flows, from the corridor to the trunk sewer, will likely require upgrades in some areas. Water: Additional watermain works will likely be required for system looping. Specifically a watermain upgrade on Yonge between Big Bay Point Road and Little Avenue is anticipated. Essa Road Nodes and Corridors Sanitary: The existing industrial trunk sanitary sewers will be reaching the end of their service life and will be requiring replacement along with capacity upgrades to convey additional flows from intensification. Local sewers do not exist south of Ferndale Drive, and would be required to accommodate intensification of the corridor. Water: Additional watermain works will likely be required for system looping. GHD City of Barrie AM Plan Appendix A: Environmental 23

29 Dunlop Street Nodes and Corridors Sanitary: The corridor area west of Ferndale Drive has limited servicing. Additional local sewers would have to be constructed along the Dunlop Street right of way. The industrial trunk sewer would also require upgrade in areas due to lack of capacity. Bayfield Street Nodes and Corridors Sanitary: The sanitary sewer should be adequate but this needs to be confirmed through modeling. Duckworth/Codrington Street Nodes and Corridors Sanitary: The existing sewers along the corridor will be reaching the end of their service life and will be requiring replacement along with capacity upgrades to convey additional flows from intensification. 4.4 Factors Influencing Demand Multiple interconnected factors will continue to influence demand for assets within the Environmental Services portfolio. These factors are outlined below in Table 4-1: Table 4-1 Factors Affecting Future Demand Factor Development and population growth Weather patterns and global climate change Consumer preference Legislation Discussion Development and population growth are significant factors influencing future water demand for the City of Barrie The City of Barrie has identified eight key elements for focus in its Strategic Plan. This includes directing and managing economic development for attracting, promoting and engaging industry for the purpose of establishing the City as a centre for excellence in innovation and entrepreneurship. The City has also identified the management of this approaching growth period as priority. This includes the allocation and planning of employment and annexed lands whereby growth will be within these designated growth areas. Weather patterns influence the demand for services within the City of Barrie. The variation in monthly demand for several assets within the Environmental Services portfolio can be attributed to the natural cyclical seasonal variation and does not impact long term demand. However, long term cyclical variations, such as El Nino and enhanced human influenced global climate change, can influence air temperatures and have the potential to influence the resulting long term future demand for assets. Consumer preference can influence demand is linked to user attitudes and behaviours. Understanding consumer preference is critical to understanding the potential for which demand management technics can be used to influence consumers and subsequently control future demand. This includes sustainable development which strives to foster and support a wide range of solutions to meet evolving community needs. The preference of customers within the City of Barrie has been examined via a citizen satisfaction report which strives to represent customer opinions against a scale of priority. Many assets within the Environmental Services portfolio are regarded by citizens as a generally expected part of their lifestyle. Legislation and policy changes, perhaps as far reaching one day as to affect building codes to restrict water usage of appliances, can have both a direct and indirect influence on the future demand for the City of Barrie s Environmental Services asset portfolio.

30 Factor Technology change and usage efficiency Network and operational efficiency Discussion and tax incentives can also influence demand through the pricing signal it sends to primary customers. Technology changes increasing efficiency can result in the obsolescence or substitution of fixed assets. This can influence future residential, industrial and commercial demand. Software can enable structured network analysis and renewal prioritization against specified criteria such as levels of services and demand divers to ensure the City continues to meet ongoing asset needs. Real time monitoring and control can used to control capacity, which can increase infrastructure asset life and yield maximum economic benefits for meeting short term changes in demand. Business improvement initiatives such as performance monitoring, leakage identification and repair and registered metering can be expected to result in a reduction of asset demand for the City. The adoption of genetic algorithms and heuristic modelling techniques can yield greater network efficiencies and can increase capacity to meet the short term needs of a growing community. 4.5 Projected Growth and Demand on Services Development and population forecasts along with future demand projects for the City of Barrie are currently under study for the upcoming Master Plan. Population growth along with industrial and commercial growth and other growth forecasts or projections for existing urban areas, designated growth areas and rural regions within the City of Barrie and annexed lands will be included in the next set of asset management plans. It is recommended that an understanding of all users, especially including those which consume services at a higher rate than others, be projected or the City such that demand on services can be planned for and met adequately. It is important to note that residential demand may fall from current consumption should the City implement demand management plans, usage efficiency improvement programs or increase the density of residential housing development within growth areas. An understanding of regional, provincial and national demand is also suggested to understand alignments and variances between the City of Barrie growth forecasts and Statistics Canada forecasts to ensure confidence in any projected estimations. 4.6 Impact of Changes in Demand of Asset Utilization There is expected to be minimal material impacts to demand within this period covered by this AMP due to the nature of supply in services generated by the City of Barrie s Environmental Services asset portfolio. Demand and demand impacts will be met by sufficient capacity provided by the new surface water treatment plant (currently in testing phase with first water expected to be distributed before end of year end, 2011) while the continued development of existing and growth areas can be expected to be serviced through capacity in existing infrastructure assets.

31 5. Lifecycle Analysis This section of the AMP describes the Environmental Services infrastructure assets for which the City of Barrie is responsible. Information is provided about the maintenance plan, renewal and replacement plan and creation/acquisition/augmentation plan works. This includes Estimated Remaining Life Maximum Potential Life Asset Consumption Estimates Assigned Consequence of Failure Values and Asset Redundancies. 5.1 Estimated Remaining Life The imminent failure mode for an asset is defined as the failure mode with the lowest estimated remaining life. Asset remaining life was estimated using various techniques, depending on the asset type, as described below, however, the dominate strategy is physical mortality of the asset only (maximum potential life). Water and Wastewater Facility Assets For the majority of facilities, the remaining life of asset components was determined based on the estimated maximum potential life, the year installed and the calculated age. Comparing the calculated age with the estimated maximum potential life for the asset component provides a proxy of the condition that the assets may be in. The maximum potential lives are provided in Section 5.2. For the water pumping stations and wells, the remaining life was based on the probability of failure, as estimated by City staff at the AM Plan workshop. Linear Wastewater (Sewer) Mains The method for assessing pipe condition ratings, which assists in determine remaining life is as follows: 1. Determine Material 2. Determine the age of construction for the pipe section 3. With this information apply the following assessment (rankings out of 5) GHD City of Barrie AM Plan Appendix A: Environmental 26

The defect severity is rated 1-5 (5 being the worst). From the CCTV video data determine the defect density this rating is assessed in the video process. The defect severity is rated 1-5 (5 being the worst). With these three values apply the following formula to determine the condition rating: Condition Rating = Age Material Rating + Defect Severity + Defect Density 3 Effective Life Consumed was calculated as -0.05CR^ CR 0.5, where CR is the Condition Rating determined using the above formula (this is a best fit equation for a deterioration curve (reference NRC MIIP Report: The State of Canadian Sewers Analysis of Asset Inventory and Condition, 2006).

(Series1) Note that the MPL s for storm and sanitary sewers were modified from a generic 85 years to reflect the material type (as recommended in the above listed document). Linear Water For linear water (watermains), the remaining life was determined based on a Maximum Potential Life of 85 years, modified by: Year Installed and Age of Pipe: The age of pipes was calculated from the installation dates of the pipes. This data, when combined with the estimated maximum potential life (85 years), gives an indication of the condition that the pipes may be in. Break History: The history of main breaks can be a predictor of future breaks or other failures. The break history data was provided by City and used to estimate whether the expected physical effective lives of the pipes should be reduced, according to the following table. For example, if a watermain has a maximum potential life of 85 years, is 50 years old with 2 breaks within its history, the estimated remaining life is calculated as follows.

34 5.2 Maximum Potential Life (MPL) The MPL for environmental assets was discussed at the AM Plan workshops held with the City s maintenance and operational staff. Due to lack of data on assets to determine the MPL, MPL has been derived from the age or condition of the asset for all assets in the environmental portfolio. The MPL for environmental services assets are summarised below.
