Dear Sir,
RE: OPW 13/0022: 2 Lot Subdivision at 411 Black Pinch Road, Cootharaba

We are writing on behalf of our clients Hans and Denise Herrle in relation to the OPW
information request dated 24-1-13 and Reconfiguration Approval, we enclose plans 1314-01 and
1314-02.

1. House Site:

The proposed house site is generally to Cardno Drawing 242001-001, except the area is to
be reduced as shown on drawing 1314-02 to allow for fire fighting vehicle turning and garage
pad only. The owners propose that to minimize cut and fill and impact a pole home is the
most sensible option to enable this house site with views to be used. This change will roughly
halve the house site area and reduce the fill height significantly (from 7m to 4m).

The total cut and fill will be: 5m cut, 4m fill. While this is more than the 2m amount specified
in Condition 12 of the Reconfiguration (REC) Approval a flat area is necessary to comply with
OPW requirement for emergency vehicle turn area.

As per Condition 11 of the REC Approval a Geotechnical Report for Slope Stability
Assessment has been carried out for this site and proposed house site cut/fill depths (see
Figure 1 of Cardno Bowler Report 10360ds.12 Dated 6-3-2012). The Report classifies the
site as ‘... ‘low likelihood of instability’ therefore the previous Council limit of 2m is considered
superceeded as the nominated house site has now been addressed by a Geotechnical
Engineer.

2. Fire Fighting Turning area:

Please refer to Plan 1314-02 showing turning area for a Fire Fighting vehicle on the house
pad area.

3. Passing Bays Proposed:

There are three existing locations where passing bays can be formalized with a small amount
of earthworks prior to the site, see attached plan 1314-01. Due to the minor nature the works
will be marked out on site and confirmed at the pre-start meeting with Council inspector. A
separate Operational Works application is not considered necessary and details are shown
below.
