    •    Accordingly, no earthworks are proposed within the road reserve or verge.
    •    The proposal does not modify the existing driveway crossover connection to Bayview Road. The
         works are limited to an extension of the internal driveway within the road verge. As such, the existing
         interface with the road network remains unchanged.
    •    The proposed extension of the driveway grades are in the order of 1:15 (6.7%), which is compliant
         with typical residential access requirements.
         i)       With respect to vehicle access, a review of the existing crossover geometry indicates that it
                  does not strictly satisfy current scraping clearance criteria. However:
         ii)      No changes are proposed to the existing crossover levels or geometry; and
         iii)     The property owner has raised no concerns regarding vehicle access or ground clearance
                  under existing conditions.

On this basis, demonstrating B85 compliance at the road interface is not considered applicable to the proposed
works, as no alteration to this section of the driveway is proposed.

    •    Stormwater runoff from the additional driveway area (approximately 16 m²) will be managed in
         accordance with the existing site conditions. Runoff will be directed downslope of the existing
         dwelling, discharging in a manner consistent with the natural overland flow path toward the adjoining
         reserve. Given the minor increase in impervious area, no adverse impacts are anticipated.
