City of Stirling Parks and Open Space Asset Managment Plan

5.3 Renewal/replacement plan Renewal and replacement expenditure is major work which does not increase the asset’s design capacity but restores, rehabilitates, replaces or renews an existing asset to its original service potential. Work over and above restoring an asset to original service potential is considered to be an upgrade/expansion or new work expenditure resulting in additional future operations and maintenance costs. 5.3.1 Renewal ranking criteria Asset renewal and replacement is typically undertaken to either: • Ensure the reliability of the existing infrastructure to deliver the service it was constructed to facilitate (eg, replacing a bridge that has a five tonne load limit)

• Ensure the infrastructure is of sufficient quality to meet the service requirements (eg, modifying the roughness of a road) 7 . It is possible to get some indication of capital renewal and replacement priorities by identifying assets or asset groups that: • Have a high consequence of failure • Have high use and subsequent impact on users would be greatest • Have a total value representing the greatest net value • Have the highest average age relative to their expected lives • Are identified in the PAMP as key cost factors

• Have high operational or maintenance costs

• Have replacement with a modern equivalent asset that would provide the equivalent service at a saving 8 . Different park asset types require different priority rankings. The ranking criteria used to determine priority of identified renewal and replacement proposals for local reserve and community parks and summary is detailed in below Figure 5.3.1.

Assessment phase

394 local and community reserves were assessed and scored with regard to: • Density of the surrounding suburb • Economic disadvantage in the surrounding suburb • Reserve access and distribution • The condition and level of amenity in each reserve

• 52 reserves were found to be a very high priority for an upgrade or minor upgrade • 99 reserves were found to be a high priority for an upgrade or minor upgrade • The combined 151 high and very high priority reserves are budgeted in the capital works program • It would be desirable, but not essential to upgrade a further 145 reserves that received a low to medium priority score. These are not budgeted in the 10-year capital works program • 34 reserves across the City would benefit some very minor landscape improvements • which will be undertaken as part of the City-wide asset refurbishment program • There are 35 reserves that are in excellent condition or have recently been subject to an upgrade, and should not be considered for further works in the short to medium term
