This report addresses engineering considerations such as access, site works, servicing provisions, and
stormwater quality and quantity requirements for site-based stormwater management.



2       Proposed Development
The proposed works consists of a 9-unit multi-residential development, with access from School Street.
The proposed dwelling configuration is shown on the design drawings comprising of 2 x 3 bedroom and
7 x 2 bedroom attached dwellings.



3       Access
3.1      Road Classification & Driveway Type
Access to the development is provided via a concrete crossover in accordance with Council and IPWEA
requirements fronting School Street. Internal shared driveway comply with minimum widths set out in
AS2890.1 for off street car parking.
TABLE 1 – ROAD & DRIVEWAY TYPE

 Description                      Standard
 School Street (Existing)         Minor Distributor
 Shared Access/Driveway           2 lane general wide heavy duty crossover. Internal driveway
                                  generally 1 lane width with passing opportunities and apron width to
                                  garage entrances.
The frontage road classification only requires footpath to one side. Assessment of the surrounding path
network shows existing paths to the West and East of the subject site are located on the opposite side
of the road. Therefore no frontage paths have been provided for the development. The frontage will be
provided with kerb and channel and standard verge arrangements to meet Council road classification
requirements as shown on the drawings.

3.2     Parking
Based on the proposed dwelling types, a total of three (3) off-street visitor parking spaces have been
provided within the development site in accordance with the NSC Transport and Parking Code. Each
on-site parking space has been designed to accommodate forward entry in a single manoeuvre for B85
vehicles and up to a three-point manoeuvre for B99 vehicles, with the exception of visitor park 3, which
is generally reverse entry only.

3.3     Sight Distances
The development provides internal sight visibility along the shared driveway. The frontage road speed
is not posted and therefore a default posted speed of 50km/h has been adopted, requiring a minimum
sight distance of is 69m. Access sight distance has been assessed and achieved in accordance with
AS2890.1 ‘other than domestic’ requirements, being 3 or more dwellings.

3.4     Vehicle Turn Paths
Vehicle turn paths have been checked for the site layout and access as shown by the vehicle tracking
plans. B85 and B99 vehicles are shown to access each of the garages and proposed car parks. Internal
Service Vehicles are not required.
