major structures along the routes.
Plant palettes were developed in consultation with the Botanic Gardens and Parks Authority (Kings Park) to emphasise foliage contrasts and achieve complementary mixes of year round flowering species.
In feature landscape areas, plant materials are contrasted with hard landscaping including resin bound gravels separated from planting areas with edging. Hard and soft landscape construction was carried out by Main Roads.
Large areas of landscaping are being established without irrigation and site preparation, timing of planting, favourable winter rains and follow up maintenance will be critical to successful establishment.
The WCI scope includes the development of a maintenance strategy to ensure landscape treatments are consolidated and reinforced in future years
