2.12 Managing the
environment
The Cockburn coast developable area can be considered as
possessing limited environment value. Much of the area has been
heavily impacted by a long history of industrial land use. Obvious
environmental values are generally limited to the coastal foreshore,
the ridge situated 1.5 kilometres from the coast, and the area
identified as Manning Reserve and Beeliar Regional Park which are
situated east of the ridge. The structure plan generally limits
impacts to these areas (with the exception of the proposed
Cockburn Coast Drive road reserve). Impacts to vegetation on the
ridge can be limited by the selection of alignment, construction
management and rehabilitation. Some disturbance to vegetation
may also result from the development proposed west of the freight
ail line at the Power Station precinct.
The redevelopment of the Cockburn coast represents an
opportunity to improve the environmental values of the area.
Potential improvements include:
• Management of surface and groundwater systems –
infiltration of groundwater to be moved away from areas of
known contamination, reducing the rate for contaminants
to be discharged to the ocean via groundwater;
• Management of superficial aquifer extraction, limiting
potential for salt intrusion into the superficial aquifer and
use of contaminated groundwater for unsuitable purposes;
• Restoration of foreshore and ridge vegetation;
• Vegetated connectivity restored between the foreshore
and ridge; and
• Economic opportunities allowing historic contamination to
be identified and remediated, rejuvenating the land.
The environmental analysis undertaken for Cockburn coast
indicates that the planning process and associated regulatory
instruments are sufficient to assess in more detail and manage the
identified environmental factors. The implementation of the
recommended management plans will require the identification of
the ultimate development vehicle; however, the proposed conditions
are versatile and can be applied to a redevelopment authority or
standard MRS and local structure planning approach.
2.12.1 Biodiversity and multi use corridors
There are opportunities to retain existing remnant vegetation
particularly west of the proposed Cockburn Coast Drive alignment,
and link this existing vegetation with vegetated corridors extending
from the ridge to the coastal foreshore vegetation. The structure
plan provides for two of these corridors. The corridors are
recommended to be approximately 30 to 60 metres in width with a
minimum vegetation coverage of 50 per cent in any one area so as
to provide a vegetation corridor sufficient to represent ecological
value. Other functions for these corridors may include drainage and
active and passive public open space.
2.12.2 Flora and vegetation impacts
2.12.2.1 TEC's and Priority Flora
A vegetation survey was undertaken in Spring 2007 to determine the
nature and condition of vegetation within the district structure plan
area, more specifically those areas within the existing Parks and
Recreation reserve and Primary Regional Road (PRR) reserve which
are likely to be impacted by the proposed development.
In surveying the coastal foreshore, Primary Regional Road
reservation and Parks and Recreation land west of the PRR reserve,
no plant taxa gazetted as Declared Rare, Endangered or Vulnerable
were located during the survey. One population of the Priority Four
species Dodonaea hackettiana was found in the study area,
however this was located outside of the area impacted by the
district structure plan area and is protected by Bush Forever.
The condition of vegetation across the site was considered to range
from Very Good, where remnant native vegetation has been
excluded from clearing, to Completely Degraded in cleared and
developed areas.
2.12.2.2 Impacted areas of Parks and Recreation reserve
The structure plan identifies three areas of vegetation which are
currently reserved for Parks and Recreation purposes under the
Metropolitan Region Scheme, potentially impacted by development
of either built form or road networks.
Beeliar Regional Park
To the extent possible, Cockburn Coast Drive has been designed to
be responsive to the ridgeline adjacent to the redevelopment area
and minimise impact on Beeliar Regional Park.
The vegetation potentially impacted is primarily located both within
the existing Primary Regional Roads (PRR) reservation and the
Parks and Recreation reserve located between the western edge of
the road reservation and east of the existing private propertly line.
Neither of these parts of the reserve however are located within the
Beeliar Regional Park Management Plan area, which extends from
the eastern boundary of the existing PRR reservation.
