            The subject section of Gympie Kin Kin Road is a state controlled sealed rural road with a
            posted speed limit of 80km/h. The site visit was undertaken on the 16/05/22 to examine
            the proposed access point and investigate sight distances at the proposed access location.
            This assessment has been supported by a sight line analysis using Noosa councils
            interactive maps to determine distances.

            The accompanying line of sight plans provided show the distance available (clear of trees
            and obstructions), with the following figures (Figure 2 to Figure 5) demonstrating the line of
            sight from these locations. These sight distances are summarised below.

                    -   Proposed driveway access Gympie Kin Kin Road
                           o Sight distance southwest – 125m (recommend to maintain slashing of bank
                              to ensure clear line of sight available)
                           o Sight distance northeast – 380m

            Australian Standard AS2870.1 2004: Off-Street Car Parking section 3.2.4 provides sight
            distance requirements for access driveway exits. For an access driveway fronting an
            80km/hr road to achieve a desirable 5s gap to enter traffic, a sight distance of 111m is
            required, with absolute minimum of 105m acceptable.

            Assessed against this criteria, the location of the existing driveway access is able to
            demonstrate a compliant sight distance of 125m to the west and 380m to east available as
            per the attached plans. All line of sights provided are to be a minimum of 300mm clear of
            trees and vegetation to ensure clear line of sight is available. It is recommended that the
            vegetation on the northern bank of the road in section A-B be maintained to ensure a clear
            line of sight is available.

            Based on this analysis, the sight distances at the existing access location meets or exceeds
            the required sight distance for a 80km/h local speed environment with a desirable 5 second
            gap acceptance, and therefore provides appropriate visibility for safe access.

            Yours faithfully,
