Infrastructure Definition Municipal infrastructure is the collection of various physical assets which are managed and maintained by a municipality to provide services or benefits to its residents and businesses.

City of Victoria Infrastructure Examples  Parks, Public Art, Trails, Trees, Shoreline,  Roads, Sidewalks, Plazas, Streetlights, Bridges,  Vehicles, Machinery, Tools,  Underground Pipes, Pump stations, Hydrants,  Civic Facilities, Furniture, Computers.

City of Victoria Infrastructure  Our municipal infrastructure is vital in sustaining the economic, environmental, social and cultural life of the community.  The quality of life enjoyed by City’s citizens is directly related to the condition of the infrastructure, such as the condition of our roads.  The Engineering Department manages approximately $1.7 billion in infrastructure, excluding land value.

City of Victoria Infrastructure  The City’s infrastructure is amongst the oldest in Canada, with some built prior to the turn of the last century.  Much of it is nearing, or has exceeded, the end of its design life.  A multi-faceted approach is required to maintain it in good condition.  Development of Master Plans and an Integrated Asset Management Strategy have started.

Infrastructure Inventory Infrastructure Type Description Civic Facilities 70 buildings and ancillary structures Water System 329 km of main, 19,500 services Storm Drain System 255 km of main, 10,000 services Sanitary Sewer System 241 km of main, 14,000 services Roads and Sidewalks 278 km of road, 453 km of sidewalks Fleet and Equipment 262 vehicles and equipment Street Lights 6,473 units and 728 cluster lights Bridges Johnson Street, Point Ellice, Gorge Road

Civic Facilities Parkades Police Station City Hall Community Centres Fire Stations

Civic Facilities Challenges  Need to upgrade buildings to meet current code for safety, health, seismic and working conditions.  Need to minimize risk and liability with aging buildings.  Continuous increase in the cost of repairing and replacing civic facilities (historically >inflation)  Need to preserve historical and heritage buildings and structures.  Rationalize and review our service delivery and programming needs in the city.

Water System Challenges  Water mains first installed in the late 1800’s  It is expected that 60% of all pipes will need to be renewed within the next 40 to 50 years.  A major portion of the downtown (high pressure) fire system will need to be renewed in the next 10 years to provide improved seismic resilience.  The cost of repairing and replacing the water system has increased dramatically over the past several years (>inflation).

Water System  Significant system improvement have been made in the past three years including a $10 million renewal of the large diameter steel watermains.  A total of over $20 million has been invested in the last 10 years on water main renewal. This amounts to over 28km of main or 8% of the system. Steel Water main Renewal

Storm Drain System Mains Catch Basins Manholes Outfall

Storm Drain System - Age Profile 70,000 Length of Pipe Installed(m) 60,000 50,000 40,000 30,000 20,000 10,000 0 Prior 1900- 1910- 1920- 1930- 1940- 1950- 1960- 1970- 1980- 1990- 2000- to 1909 1919 1929 1939 1949 1959 1969 1979 1989 1999 2007 1900 Year of Installation

Storm Drains  Storm drains first installed in the late 1800’s  The majority of storm drains have now been inspected using CCTV cameras. Condition assessment results indicate the majority of pipes, 89% are in average to very good condition, however, 11% of the pipes are in poor or near failure condition.  It is expected that 80% of all pipes will need to be renewed within the next 40 to 50 years.  Cost of repairing and replacing the storm drain system has increased significantly over the last several years (>inflation).  Our commitments to monitor and control the quality of storm water discharges is increasing (i.e., Bowker Creek).

Sanitary Sewer System Mains Pump Stations Manholes

Sanitary Sewer System - Age Profile 120,000 Length of Pipe Installed(m) 100,000 80,000 60,000 40,000 20,000 0 Prior 1900- 1910- 1920- 1930- 1940- 1950- 1960- 1970- 1980- 1990- 2000- to 1909 1919 1929 1939 1949 1959 1969 1979 1989 1999 2007 1900 Year of Installation

Sanitary Sewer System Challenges  Sanitary Sewers first installed in the late 1800’s  The majority of sanitary sewer pipes have now been inspected using CCTV cameras. Condition assessment results indicate that the majority of the pipes, 92% are in average to very good condition, however, 8% of the pipes are in poor or near failure condition.  It is expected that 82% of all pipes will need to be renewed within the next 40 to 50 years.  The cost of repairing and replacing the sewer system has increased significantly (>inflation).  A high percentage of extraneous water is entering the sewer system (inflow and infiltration).  Increased development densities are resulting in capacity demand.

Road and Sidewalk Network Roads Sidewalks

Road and Sidewalk Network Challenges  Heightened expectations re. smooth surface conditions. More frequent maintenance is needed to manage safety/liability issues (trip hazards/potholes).  Previous maintenance deferrals have resulted in an increased scope of work for required repairs.  Component costs for repairs (oil, aggregates, etc) is increasing a rate greater than inflation.

Street Lighting & Traffic Signals Davit Fixtures Cobra Fixtures Cluster Fixtures

Street Lighting & Traffic Signal Challenges  Non-galvanized street light poles have exceeded their design life (20 years).  Larger traffic signal heads increases pole loading.  Road users requests for increased services (audible pedestrian signals, countdown signals) increases inventory.  Aging infrastructure results in increased service calls / outages and increased safety and liability issues.

Master Planning Studies  Master Planning Studies:  Water System Master Plan  Storm Drain Master Plan  Sanitary Sewer Master Plan  Road Network Plan  Facilities Capital Plan  Urban Forest Plan  Parks Master Plan  Asset Management Strategy

Asset Management Strategy  The City is currently developing an Integrated Asset Management Strategy. Asset Management Definition An integrated approach involving planning, finance, engineering and operations to effectively manage existing and new infrastructure to maximize benefits, reduce risks and provide satisfactory levels of service to community users in a socially, environmentally, and economically sustainable manner.

Asset Management Strategy … Cont’d  Asset management is a business strategy to help the City address the problems of aging infrastructure and improve long-term planning and finance options.  Asset management is a series of process and information improvements that enable you to see not only the likely consequences of the decisions you take today - but also of the actions you don’t take.  When you are armed with a knowledge of the consequences you can make better decisions.

Asset Management Strategy … Cont’d  Asset Management processes and decisions will…  Assist Council in making informed and fiscally prudent decisions.  Enhance Customer experience  Proactively support and facilitate economic development and innovation  Proactively support cost efficiency and financial sustainability  Proactively support the protection and maintenance of a healthy environment for current and future generations  Proactively support safety, durability and energy efficiency of built environments  Optimize Capital Budgeting – prioritize projects and improve the understanding of current and future funding needs.
