1.0 INTRODUCTION
This engineering report is lodged in support of a Reconfiguration of Lot
application seeking to develop a 1 into 2 lot rural residential subdivision and new
driveway at 108 Black Mountain Range Road, Black Mountain, also described as
Lot 2 RP131369
This report addresses relevant engineering issues and should be read in
conjunction with attached layout plan and engineering drawings.
Importantly, this report seeks to address civil engineering issues at a level
appropriate for a Development Application.
Figure 1.0 depicts lot configuration of the proposed development.

2.0 SITE DESCRIPTION
The subject site is located on 108 Black Mountain Range Road, Black Mountain
(Lot 2 RP131369). At present the site consist of a single dwelling with remainder
of the site covered in grass and vegetation. The site is approximately 5.977Ha
with the front half of the property sloping at approximately 22% from South to
North. The back portion of the property consists of a gully that runs through the
centre, towards the South-East corner. The land slopes at approximately 20%
towards the gully. The existing house at the front of the property will remain.

Minor earthworks including the construction of a two-tier retaining wall has
previously been completed along part of the front western boundary.
Figure 2.0 depicts locality of the proposed development.
Figure 2.0 – Locality Plan
3.0 BULK EARTHWORKS
The development requires minor earthworks and retaining walls to construct the
access driveway. A slope stability report has been undertaken by tectonic Pty Ltd
which identifies the works can proceed with the appropriate factors of safety.
Refer Tectonic Report 202332-001-Rev0.
4.0 ACCESS
Access to the subdivision will be taken from Black Mountain Range Road. A new
residential driveway is proposed to access the new allotment. The existing access
crossover will be sealed and constructed in accordance with council standard
drawings.

Section 5
Refer to Appendix B for preliminary infrastructure plans which identify
proposed road cross sections and layouts.
4.1 Sight Stopping Distance
A sight stopping distance study was completed for the development. The
findings show that the southern uphill approach to the proposed driveway
access is adequate for design speed of 90km/h (sign posted 80km/h plus
10km/h). The actual stopping site distance for the northern approach which is
downhill satisfies a design speed of 80km/h with 1.5seconds reaction time. It is
considered a reaction time of 1.5 seconds to be suitable for this location as there is
an existing intersection to the south of the proposed development. The existing
horizontal curve of Black Mountain Range Road at the location of the proposed
access is approximately 167m which caters for a design speed of 80km/h. We
note the posted speed is 80km/h, however with the constraints of the existing
horizontal curve, the available sight distance is adequate. It should be noted the
access location is an existing driveway.
5.0 STORMWATER MANAGEMENT
5.1 Stormwater Connection and legal point of discharge
The existing dwelling utilises rainwater tanks for water supply. Surcharge
from rainwater tanks sheet flows towards existing stabilised steep
vegetated gullies.
The proposed building envelope for lot 2 is clear of lot 1 existing discharge
locations and will not suffer from nuisance flows.
Similarly proposed lot 2 will require rainwater tanks for water supply and
irrigation/reuse. Should the tanks become full or overflow a level
spreader will see discharge returned to sheet flow toward existing gullies.
There are no properties downstream that can be impacted by nuisance
flows.
6.0 SEWERAGE
The existing property is serviced via an onsite effluent disposal system. It is
proposed that the new allotment be serviced via similar system. Detail design of
the system will be undertaken by a suitably qualified consultant at BA.

Section 6
7.0 WATER
Water supply to the existing allotment and proposed lot 2 will be via rainwater
tanks sized to BCA requirements.
8.0 CONCLUSION
The proposed 2 lot subdivision over existing Lot 2 RP131369 can be serviced by
the use of roof water tanks and on site sewer effluent disposal systems. Access to
the site will be via Black Mountain Road Range and the existing driveway.
There are no constraints or impediments to the proposed residential development
that cannot be overcome with good operational work engineering design.
