Appendix D Site Access & Intersection Investigation

2.0 Impacts to existing intersection (Uhlmanns & Northmount)

The existing Uhlmanns Rd and Northmount Rd intersections appears to operate as an unsigned T-
intersection. This is assumed to operate sufficiently due to the low traffic volumes and generally low speed
environment.

The proposed driveway will service a single rural residential lot and as such, the increase to traffic volumes
are estimated to be very low (1-2 peak hour movements only).
Contour has assessed (2) options for improving the intersection as follows:

1. Giving Northmount Road priority and Installing a Give Way sign on the Uhlmanns Road southern leg of
   the intersection (refer to Figure 10), however sight distance checks indicate that approx. 38.3m sight
   distance is achievable along Northmount Rd due to the presence of a crest. Significant roadworks
   would be necessary to increase the sight distance to be compliant with Austroads Guide to Road
   Design (AGRD). Therefore this option is considered undesirable.

    Refer to Attachment D – Drawing 3225-SK11 for more details of this option assessment.

2. Giving Uhlmanns Road priority and Installing a Give Way sign on the Northmount Road leg of the
   intersection (Figure 11), with sight distances compliant with Austroads Guide to Road Design (AGRD)
   achievable with minor vegetation clearing on the eastern verge of Uhlmanns Rd (south) and to the
   North without any changes to Uhlmanns Rd (north).
