Only one project, Edmondson Park, was included in this year’s
results, since North Penrith, our other relevant masterplanned
project, requires no riparian corridor management (because it
has no riparian corridor).
Where applicable, all targets were met. Indicators relating to
third order or greater streams were not applicable this year,
because there were no such streams identified within the
project area.
Our riparian zone and vegetation buffer targets were met.
A 20m core riparian zone and 10m buffer will be maintained.
Maxwell’s Creek, a second order stream, is heavily wooded
in the upper catchment. There is a large spillway and culverts
that prevent the passage of fish and other aquatic species
into the lower reaches. Erosion is evident and there is sewage
discharge from the Ingleburn sewage treatment plant that has
contributed to reduced water quality.
Within the project site, the creek line has variable cover of
native vegetation and permanent water. Maxwell’s Creek’s
tributaries are highly modified and as a consequence, there is
little or no permanent flowing water to provide a habitat for
fish.
An appropriate riparian corridor management plan for
Edmondson Park will ensure that barriers to fish passage are
removed and replaced with appropriate structures, the area is
revegetated to provide habitat for native flora and fauna, the
water quality is improved and bank erosion is prevented. In
addition, bank and stream channels will be rehabilitated where
these have been impacted by land use.
There were no in-stream breaks resulting from Landcom’s
design for second order streams in this reporting period.
One first order watercourse, 494m long, will be in-filled for
development and there are 2.9ha of riparian land zoned
for environmental protection. There are no Ramsar or other
important wetlands in the Edmondson Park area.
