Dear Sir,

RE:

OPERATIONAL WORKS APPLICATION (BULK EARTHWORKS) FOR Elm Street,
and 61 Lake Macdonald Drive, COOROY (Lot 135 MCH 978 & Lot 5 SP 266731)
REC13/0148, MCU13/0226, OPW16/0007

We are responding to the ‘Not Properly Made’ letter dated 10-2-16 for Operational Works Bulk
Earthworks approval at 154 Elm Street, Cooroy.

We understand there are two issues: fee is not acceptable, and Council query need for Bulk
Earthworks and clearing prior to finalization of subdivision.

Historical background of Erindale Park Subdivision:

Stages 1 (4 lots), 2 (3 lots), and 5/6 (9 lots) have been completed separately over the last
two years, Stage 1 construction started in August 2013.

One owner purchased the land some time ago and has continued to develop the
property.

We have approval for Stage 3 Operational Works which is planned to start construction
in April this year.

Main reasons why Stage 4 needs bulk earthworks prior to completion of subdivision:

Stage 3 construction requires 2600 cubic metres of imported fill (in addition to cut-fill on
site). This is required to obtain flood freeboard in accordance with flood study.

Cost to import this amount of fill is approximately $104,000 (estimated $40/cum), cost to
cut from Stage 4 and cart a small distance to fill estimated as $65,000 (at $25/cum). The
cost difference to import fill is therefore $39,000.

Importing 2600 cum of fill using truck and dog at 20cum/load requires 130 return trips to
the site on Council roads. This is not desirable for roads or local residents. The soil can
be moved onsite using dump trucks without using Council roads which is far less impact
on community.

Stage 3 has approximately 3800 cubic metres of excess topsoil, tests show a topsoil
depth of 200-400mm which has been encountered on other Stages. Stage 4 is an old
TMR quarry and has a lack of topsoil, so it is planned to take topsoil from adjacent Stage
3 to Stage 4. Again it is better for cost and roads/community if the transport of material is
kept between the two sites.
