Maitland publishes some standard drawings which may be very handy for people such as myself who are trying to get a handle on the requirements for improvements and additions to a house.

To get them:
Go to Maitland Councils Website
Hover over Planning & Development
Three up from the bottom click on the Planning & Engineering Publications
Under the heading "Manual of Engineering Standards"
Click on the here link which takes you here
Under Section D you have a whole lot of Standard Drawings.

I was interested in my driveway so I needed the SD001 to SD0015 drawing which has all sorts of profiles for driveways.

Interestingly they specify slopes not in degrees but in percentage points.

http://en.wikipedia.org/wiki/Grade_(slope)

Check the calculation of percentage grade on the above mentioned wikipedia article

$latex percentage = 100 \frac{rise}{run} $

$latex 8.5\% = 100 \frac{rise}{1400} $

$latex rise = \frac{8.5\times1400}{100} $

Given the percentage slope you can figure out the rise when you have the run and vice versa
