Marsden Park facts behind the job
Blacktown City Council
Marsden Park is one of Blacktown City's 54 residential suburbs. Council says 12 of the North West Growth Area's 16 precincts are in Blacktown City.
Up to 10,300 new homes
The NSW Government says the new Marsden Park community will have up to 10,300 new homes.
Big family houses
In 2021, 97.4% of occupied homes in the suburb were separate houses and 75.9% had four or more bedrooms. Households averaged 3.4 people, and 66.5% of homes had a mortgage.
Flood limits on some land
Blacktown City Council says the NSW Government's 2022 Flood Inquiry found residential development inappropriate in parts of the Marsden Park North precinct, because of flood and evacuation risk.
Hot water for 3.4 people
Households here average 3.4 people, against 2.6 across NSW, and three in four homes have four or more bedrooms. A system sized for a smaller household will run short. Work out the right size with the hot water size tool, and see hot water repairs in Sydney if it's already failing.
Flood questions before you build
Blacktown City Council says flooding in the City comes as overland flow or riverine flooding, and its flood maps cover most of the City. Before adding a granny flat, pool or extension, request a flood advice letter for your address. The Flood Inquiry finding applies to parts of Marsden Park North, not to every street in the suburb.
New gardens, new pipes
Sydney Water says roots find their way into small cracks, and advises keeping trees at least 6 metres from wastewater pipes. On its list of trees to avoid are jacarandas, figs, liquidambars, lilly pillies, brush box and camphor laurel. Get your sewer service diagram before landscaping so you know where the line runs.
Once a tree is established, Blacktown's rules apply. A prescribed tree is more than 3 metres tall or has a trunk wider than 200mm, and cutting its roots needs consent. Council asks whether pipes can be repaired without touching the tree, considers fixes like pipe relining and root barriers first, and says a tree blocking pipes generally isn't a reason to approve removal.
Building or extending
Sydney Water asks owners to buy the right diagrams and submit plans through its Tap in service when building over or near its pipes, and to check with Council whether consent is needed. Most plans are approved straight away. A renovation may also need water saving fittings to meet BASIX.
What we would do
If you've just moved in, find your water meter, main stop tap and overflow relief gully, and take photos of each. Order the sewer service diagram before the landscaper arrives so nobody plants a fig over the sewer. And if hot water runs out with a full house, have the system sized properly before replacing it like for like. We'll match you with a plumber who specialises in that job.
