Why Regional Detention Basins Beat On-Lot OSD in Greenfield Subdivisions

On-site detention OSD in NSW has been a standard condition of subdivision consent since the early 1990s.

Half Road Construction in NSW Subdivision: What It Costs and Why It Catches Developers Off Guard

You plan on subdividing your site, the road out front is split down the middle. One half is new: clean kerb and gutter, fresh stormwater drainage, sealed pavement.

What a Subdivision Certifier Does and Why It Matters Before Construction Starts

Most people think of a Subdivision Certifier as the person who signs off at the end. That is only part of the picture. On a DA-approved subdivision, the Subdivision Certificate is issued by Council.
