Cons of buying temporary onsite stormwater detention(OSD) lots

We're looking at buying a lot and according to the developer's plan, a few lots are marked as "temporary onsite stormwater detention" - OSD lots and they are available at a discount. I am not sure what that means. Would like to know what are the issues with buying of buying OSD lots?

Thanks.

 

Essentially this would be land which will be inundated by water every time that it rains. Water will drain into the land and be stored temporarily until it drains off.

What would you build there, a pontoon?

It seems like the developer is flogging off the land which should be dedicated to council for parkland or drainage reserves.

 

Seriously?? Water drains into the land?? There are stomwater drains these days.
I guess i'll get the flood insurance then.

 

What do you think that the words "temporary onsite stormwater detention" mean?

It is not a flood, so insurance won't cover you as it's a planned occurrence.

The land forms part of the stormwater system.

 

I'd run ( or in this case swim) away fast.

 

Are the lots considerably larger than normal lots? I find it very odd as normally they would make OSD lots park of parklands/reserves as there would be no construction allowed on the OSD part of the lot. I probably wouldn't even want the risk of building on the non OSP part of a lot.

 

"temporary onside stormwater detention" from my understanding is temporary area to store stormwater during construction & will removed after construction (reform ground condition like other lot). All temporary OSDs have to be removed & permanent OSD shall be provided - usually in common area (park/reserved). Please check with developer.

 

I spent 18 months driving past a development where they had a temporary retension area, it was often full (back when it used to rain ).

When the drainage was finally finished the area was back filled and For Sale signs went up

There is a brand new house on one of the two blocks that only a few months previously was a big dam

No, not me, NEVER

 

Damned dams

 

Lies, Damned Lies and Statistics

 

63.27% of statistics are invented

 

That's only if the believe the statisticians. The pollsters believe that this number is higher or lower depending upon who you ask.

 

that would be it.
quite common to use existing dams etc as OSD's during construction. then we strip out the old dam down to existing soil, fill and repack to Geotech compaction specs. no one would ever know there had been a dam there.
it will be noted in the DA consent for the subdivision

 

But no-one reads those (especially the unsuspecting buyer).

 

@Scott No Mates
true.

 

probably more to do with subsoil water rather than rain water

quite common on large building sites and subdivisions to dewater
for excavation

allot of the time temporary OSD will be used on the lower blocks
the EPA says you cant just dump un-treated water any where you want


once the underground services and the subsoil Aggy and storm water drains have been installed there is no longer a need to dewater and or have temp OSD
