Attachment B - SCG Engineers Response

             In referencing AS2890.1-2004 we have used a frontage road speed of 40km/hr. This is due to the tight
             radius a car must travel through when approaching the proposed driveway. This will limit the vehicles
             speed to probably less the 40km/hr. The minimum site distance at this speed is 30m which, is
             achievable as shown on our revised documents.

             Following further inspection of the site it has been decided to replace the existing section of internal
             driveway. This has been shown on our revised documents.

     Items 15 & 16 – Stormwater Treatment and Levels

             The site area is less than 2500m2 which is the trigger for stormwater treatment. Regardless, we have
             proposed the inclusion of a water tank for capture of roof runoff and re-use and the construction of inline
             infiltration pits. These will in part limit nutrient and gross pollutant runoff from site.

             We have included some additional surface levels on the proposed driveway drawings to confirm the
             adequacy of the proposed stormwater drainage infrastructure.

     We trust the above information and enclosed revised drawing will address Council’s request for information.

     Please don’t hesitate to contact the undersigned should further information be required.


     Yours faithfully
