Green Infrastructure Asset Management

BARRIER
Green infrastructure not funded or managed as effectively as ‘traditional’ infrastructure because it is not formally recognized as infrastructure by decision makers.
THEORY OF CHANGE
• Green infrastructure in asset management plans will help:
▪ Improve the management of these assets
▪ Increase access to infrastructure funding programs
O. REG. 588/17

ASSET MANAGEMENT PLANNING FOR MUNICIPAL INFRASTRUCTURE
• Includes green infrastructure assets within the scope of municipal infrastructure assets.
• States that every municipality shall prepare an asset management plan in respect of all of its other municipal infrastructure assets by July 1, 2023

Integrating Green Infrastructure
10
• Advancement in green infrastructure inventories & condition assessments
• Use of ecosystem services to define and measure the levels of service
• Extensive co-benefits

• Reported separately from Tangible Capital Assets (TCAs) in this version of the AMP.
• Asset management plans do not have to follow PSAB requirements. There is flexibility to analyze non-PSAB assets.
• Important to be clear on what is being reported.
“Richmond Hill has $1.85 billion in infrastructure assets and an additional $87.6 million in
Environmental Assets.”
York Region Green Infrastructure Asset Management
• 2013 and 2015 – Green infrastructure included in state of the infrastructure reporting
• 2017 – Develop first Green Infrastructure Asset Management Plan
• Green infrastructure includes:▪ Street trees
▪ York Regional Forest
14
York Region Green Infrastructure Asset Portfolio
• Urban forest (street trees)▪ Biological – street trees, shrubs,
perennials, growing media
▪ Civil – soil cells, irrigation, drainage
• York Regional Forest▪ Biological – forest, wetland, grassland
communities
▪ Civil – trails, parking lots, fences, signs
• Bill Fisch Forest Stewardship and Education Centre
15
Valuing the Region’s Green Infrastructure
What is the most appropriate and defensible method to value biological assets?
• Street trees – Use CTLA trunk formula method
• Shrubs and perennials – replacement cost
• Growing media – replacement cost
• Forests – timber value, land value, re-establishment cost
• Wetlands and prairies – land value, re-establishment (future)
Green infrastructure portfolio valued at $488 million
16
Establishing Levels of Service
• Identifying levels of service for green infrastructure was the most challenging element of the plan
• Level of service includes:▪ Community level of service
▪ Technical level of service
▪ Performance measure
17
Asset Management Strategy – Life Cycles
• Street trees - identify three growing environments and estimate average lifespan ▪ Urban – 35 years
▪ Suburban – 44 years
▪ Rural – 53 years
• York Regional Forest – natural communities are self perpetrating (with maintenance)
18
Green Infrastructure – Asset Management Strategies
19
Green Infrastructure – Financial Strategy
• Funding plan to put asset management strategies into action, required investment to meet service levels
• Total cost for urban forestry program varied significantly depending on level of growth
• Key outcomes from financial strategy▪ Need to review service levels and return on investment for some
treatments
▪ Need to establish reserve to minimize impacts of funding peaks
20
Putting the Plan into Action
• Plan identified a number of continuous improvement initiatives:▪ Stakeholder consultation
▪ Separate operating and maintenance costs
▪ Need for a forestry replacement reserve
▪ Establish data governance model
▪ Improve age and condition data for civil assets
