Case Studies

Overview

The Case Studies area is a curated evidence library for Green Infrastructure Asset Management. It is not intended to collect every interesting project. It focuses on strong examples that show how green infrastructure assets are identified, assessed, planned, funded, maintained, monitored and improved in practice.

Case studies may include formal Asset Management Plans, operational asset-management programmes, maintenance systems, monitoring examples, funding approaches or asset-class-specific practice examples. Each case study should help practitioners understand how the LFA 3×3 Framework can be applied or adapted.

Featured case studies

Use the filters to narrow the case-study index by asset class, LFA Step or case-study type.

Asset class LFA Step Case-study type

Operational asset-management practice Tucson Water — Storm to Shade Location: Tucson, Arizona, USA Asset class: Green stormwater infrastructure / WSUD; Urban trees & canopy.

Best LFA links: Steps 1, 2, 3, 5, 7, 8 and 9.

Tucson Water’s Storm to Shade programme shows green stormwater infrastructure being managed as formal infrastructure through inventory, functionality assessment, maintenance standards, enterprise asset management, work tracking, cost capture and future maintenance-cost forecasting.

Published AMP example City of Marion — Tree Asset Management Plan Location: South Australia, Australia Asset class: Urban trees & canopy.

Best LFA links: Steps 1, 2, 3, 4, 5, 7, 8 and 9.

The City of Marion Tree Asset Management Plan is a strong Australian local-government example of an asset-specific AMP. It shows how tree assets can be addressed through asset state, Levels of Service, demand, lifecycle planning, risks, costs and financial planning.

Published AMP example City of Marion — Open Space Asset Management Plan Location: South Australia, Australia Asset class: Other / emerging. Relevant setting: parks, reserves and open-space landscapes.

Best LFA links: Steps 1, 2, 3, 4, 5, 7, 8 and 9.

The City of Marion Open Space Asset Management Plan is included as a broader public-landscape AMP example. It is useful for understanding how public landscape assets can be described, serviced, planned, costed and linked to long-term financial planning, even though open space is treated here as a setting rather than one of the six core LFA asset classes.

How case studies are classified

Each case study is classified by LFA Step, asset class, case-study type and practice theme. This allows users to browse either through the Guide method or through the type of green infrastructure asset they manage.

Case-study classification system
Classification	Purpose	Examples
LFA Step	Shows which part of the 3×3 Framework the case study best illustrates.	Step 1 asset inventory, Step 3 Levels of Service, Step 5 lifecycle strategies, Step 7 cost evidence, Step 9 monitoring.
Asset class	Helps users find examples relevant to the kind of green infrastructure they manage.	Urban trees & canopy, GSI/WSUD, green roofs and walls, waterways and wetlands, remnant bushland, coastal and foreshore landscapes.
Case-study type	Distinguishes formal AMP examples from operational, funding, monitoring or implementation examples.	Published AMP, operational asset-management practice, monitoring example, funding example.
Practice theme	Helps users find examples by the management problem they are trying to solve.	Inventory & data, service potential, lifecycle management, costs and funding, monitoring, governance.

Asset classes

The Case Studies area uses the six main LFA green infrastructure asset classes, with an additional Other / emerging category for examples that do not fit neatly into the core list. Parks, reserves, streets and public realm settings may appear across several asset classes, but are not treated here as a separate asset class.

Green infrastructure asset-class index
Asset class	What this may include	Current examples
Urban trees & canopy	Street trees, park trees, urban forest assets, canopy networks and shade corridors.	City of Marion Tree AMP; Tucson Water — Storm to Shade.
Green stormwater infrastructure / WSUD	Bioretention systems, rain gardens, swales, infiltration basins, constructed treatment wetlands, stormwater detention basins, tree pits, stormwater harvesting landscapes and water-sensitive streetscapes.	Tucson Water — Storm to Shade.
Green roofs, walls & podium landscapes	Green roofs, green walls, podium landscapes, building-integrated planting and structural greening systems.	Example to be added.
Waterways, wetlands & riparian systems	Natural and naturalised wetlands, waterways, creek corridors, riparian vegetation and floodplain landscapes.	Example to be added.
Remnant bushland, biodiversity & habitat	Remnant vegetation, conservation reserves, habitat corridors, biodiversity areas and ecological restoration assets.	Example to be added.
Coastal, foreshore & blue-green edges	Dunes, foreshores, coastal vegetation, estuarine edges, living shorelines and coastal adaptation landscapes.	Example to be added.
Other / emerging GI asset classes	Productive landscapes, community gardens or other green infrastructure types that do not fit neatly into the six main classes.	Example to be added where relevant.

Practice themes

Practice-theme index
Theme	Useful for finding examples about
Inventory & data	Asset registers, mapping, ownership, asset hierarchies and data confidence.
Condition & service potential	Condition assessment, function, performance, service potential and criticality.
Levels of Service & public value	Community outcomes, equity, climate resilience, heat, shade, biodiversity and public benefit.
Lifecycle management	Maintenance standards, renewal, rehabilitation, establishment, stewardship and intervention planning.
Costs, benefits & funding	Lifecycle costs, cost capture, benefits evidence, financial forecasting and long-term funding.
Monitoring & improvement	Inspections, work orders, dashboards, feedback loops, adaptive management and improvement actions.
Governance & delivery	Roles, responsibilities, interdepartmental coordination, contractors, delivery models and institutional arrangements.

Case-study types

Case-study types used in this library
Type	Meaning
Published AMP example	A formal Asset Management Plan or equivalent document showing how an organisation has structured asset information, service levels, lifecycle planning, risk, costs and funding.
Operational asset-management practice	A programme or system showing green infrastructure managed through inventory, inspection, maintenance, work orders, cost capture or monitoring.
Funding or financial example	A case useful for long-term funding, cost recovery, financial planning or investment justification.
Monitoring and improvement example	A case useful for performance tracking, adaptive management, improvement registers or reporting.
Asset-class practice example	A case useful because it shows how a particular GI asset class is defined, managed or renewed.

Future case-study priorities

Future case studies should be added selectively. A case study should normally be included only if it provides a clear lesson for Green Infrastructure Asset Management, demonstrates a specific part of the LFA 3×3 Framework, or expands the asset-class coverage of the library.

Priority gaps include waterways and wetlands, remnant bushland and biodiversity assets, coastal and foreshore landscapes, and Australian examples of green stormwater infrastructure or water-sensitive urban design managed through asset-management systems.
