Dear Alan,


       Re: Assessment against the Driveways and Parking Code – 3 Grady Street, Kin Kin QLD 4571

1. Overview of Proposed Works
The proposed development includes construction of a single rural driveway crossover from Grady Street to
service the subject lot. Works include a gravel driveway crossover with a sealed entry, installation of
a 375mm reinforced concrete pipe (RCP) culvert with precast headwalls, stone pitched inlet and outlet
protection, and associated earthworks to achieve suitable grades and transitions.


Compliance with Driveways and Parking Code
2.1 Location and Access
The crossover is appropriately located on Grady Street with suitable sightlines and provides a single access
point to the site, minimising vehicular conflict. The design does not adversely impact existing infrastructure or
services. The proposal complies with the intent of the code.
2.2 Design Standards
The driveway crossover is designed generally in accordance with IPWEA Standard Drawing RS-056, including
culvert installation, headwalls, and erosion protection measures. The design meets the applicable standard
requirements.
2.3 Geometry and Grades
Grades within the driveway range between approximately 3% and 16%. Transitions are provided to ensure a
smooth interface with the existing road. Steeper grades occur within the site due to topographic constraints
but do not affect safety at the road interface.
2.4 Stormwater and Drainage
Stormwater is conveyed beneath the driveway via a 375mm RCP culvert, with discharge directed to the
existing swale. Stone pitching is provided to prevent scour and maintain stable drainage conditions. The
proposal maintains existing drainage paths and does not worsen downstream impacts.
