Appendix D Site Access & Intersection Investigation

Sight Distance Assessment against AS2890.1

Contour Consulting Engineers have undertaken a site visit to review available sight distances. It is noted
that Uhlmanns Road has a posted speed of 60km/h. NSC to confirm

The Australian Standards for Off-Street Car Parking, AS2890.1 sets out sight distance requirements for
access driveways, which is specified as 55m, for a frontage road speed of 60km/h for a Domestic property
access (refer to Figure 4).
Based on our site investigations, we consider that compliant sight distances to the north for the proposed
driveway are achievable with minor tree clearing (~30m2) along the eastern Uhlmanns Road verge. Figure
6 shows the approx. area of vegetation required to be cleared to achieve adequate sight distance to the
north from the proposed driveway location.

Full Concept Plan Sight Distance against AS2890.1 sketch drawing 3225 SK-12 is included as Attachment
B to this report for reference.

Sight Distance (east) to end of Uhlmanns Road

Due to location of the proposed driveway in relation to the end of constructed road (Uhlmanns Road), sight
distance to the south is clear to the subject site’s existing driveway (approx. 20m from proposed driveway)
that coincides with the end of Uhlmanns Road/road reserve boundary. Sight distance is available from the
proposed new driveway along the existing driveway (ie into private property) – refer Figure 7 but is not
compliant with AS2890.1
