5     DEVELOPMENT IMPACTS AND MITIGATION

5.1      Flora and Vegetation Communities

5.1.1     Impacts
5.1.1.1 Removal of Native Vegetation
The majority of vegetation required to be removed to facilitate the development consists of existing
fruit tree orchards (VC1d), a small number of mature E. tereticornis (Queensland blue gum) and
Cinnamomum camphora (camphor laurel) (VC1c) and some Pinus elliotii (slash pine) within VC1d.
None of these vegetation units are captured within Council’s Biodiversity, Waterways, and Wetlands
overlay mapping.
A small amount of vegetation within the mapped Area of Biodiversity Significance and MSES
Regulated Vegetation overlay may be impacted to develop Lots 1-5. The majority of the native
vegetation at the location is growing within the Pomona Showgrounds which adjoins the southern
site boundary. Council’s mapping has included the canopy overhang of the large trees present within
the showgrounds and therefore extended the mapped Area of Biodiversity Significance and MSES
Regulated Vegetation into the site. A narrow band of vegetation is present along the site boundary
however consists of either planted fruit trees or exotic species including Cinnamomum camphora
(camphor laurel), Eugenia uniflora (Brazilian cherry), and other exotic weed species. It should be
noted that all vegetation within the mapped area which may be impacted to facilitate proposed Lots
1-5 is located within 5m of the existing boundary and therefore could likely currently be cleared under
existing boundary clearing exemptions.
It is also noted that MSES Environmental Values are mapped extending into the southern extent of
the site in the proximity to the proposed building envelope within Lot 6. This overlay is based on the
extent of Category B regulated vegetation which has been incorrectly mapped by the State in this
location. Limited woody vegetation occurs at the mapped location and it is considered that the
mapping overlay is not applicable as no remnant vegetation occurs which could be impacted by the
proposed development.
Council’s Biodiversity, Waterways, and Wetlands overlay mapping depicts a first order waterway in
proximity to the proposed Lot 6 building envelope. No formal waterway containing defined bed and/or
banks was observed in the location as mapped by Council. A small, engineered, mowed, grassy
swale was observed which would capture sheet flow from the eastern slope in prolonged rain events.
The swale would direct flows into the onsite dam. No formal spillway was observed on the dam wall
and no defined channel exiting the dam was observed, indicating that the majority of water captured
by the drainage swale would be expected to be retained within the dam. The blue hatched line in
Plate 12 depicts the condition of the mapped waterway. No woody vegetation is present flanking the
majority of the mapped waterway (precluding exotic pine trees surrounding the dam).
