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.
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.

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.

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 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
Cobra Fixtures Cluster Fixtures Davit 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.
Infrastructure Replacement Cost
Infrastructure Type Current Replacement Cost
Civic Facilities $ 209,000,000 Water System $ 262,000,000 Storm Drain System $ 362,000,000 Sanitary Sewer System $ 312,000,000 Roads / Sidewalks / Traffic Signals $ 350,000,000 Bridges / Road Support Structures $ 200,000,000 Street Lighting $ 13,000,000 All $1,708,000,000

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.
Infrastructure is critical to the economic, environmental, social and cultural sustainability of the City.
The quality of life enjoyed by the City’s citizens is directly related to the condition of the infrastructure.
The City’s infrastructure is amongst the oldest in Canada.
Much of the infrastructure is nearing the end of, or is exceeding, its design life.
Conclusions
Conclusions … Cont’d
These challenges can be addressed by continuing current initiatives: applying asset management principles. applying new technology. implementing industry best-practices. Undertaking a review of all City infrastructure (i.e.
Recreation Amenities, Parks, Technology, Equipment, Lands, Traffic Control, Streets, Waste Management Equipment, Public Art, Etc.). Building up the Reserve Funds.
“… only asking for more money and not changing the manner in which infrastructure as an asset is treated, maintained, rehabilitated and built for future needs, is an incomplete and inadequate approach..”
