While subdivisions will create a pattern that lasts for more than 100 years, many individual components within them have a limited lifespan. These can require regular maintenance or periodic renewal. Examples include:
- private stormwater detention or treatment devices
- private driveways and access ways
- private retaining structures
- areas of private covenanted bush
- private fences and barriers adjoining public roads or
- walkways communal car parking and recreation areas
These costs can be significant and, if not budgeted for by the landowner, can become financially crippling. If maintenance is not carried out, a range of serious health, safety, and amenity problems can arise.
