Advice on Drain Water Easement and Land Contour

Pbm33 on 04/11/2025 - 22:12

Hi guys, looking to purchase land to build a house and tossing up some options.

Option 1: https://imgur.com/a/Kfnr70H

Lots 136, 141, and 142 are available.

141 and 142 have drain water easements 1.5m wide, with the drain holes at the back. 136 is free of easements but I'm wondering if there is risk of water run off from 140 and/or 141 given the slope as the contours suggest.

Lot 343 is available.

Lots 318 and 344 are on a road which I suspect will be busy, and so lot 343 is only 1 lot away from this potentially busy road. Also this might be an expensively priced lot, as a buyer is looking to re-sell. How does this compare to lots in Option 1 above?

Keen to get some thoughts.

TIA.

    You need to ask a surveyor not the internet

    Take it to a few project home builders and ask them for their opinion. You might need to get past the sales person in the display home.

    Easement at the back doesn't really matter. Because its unlikely you can ever build the house that far back due to setback requirements for councils and state planning regulations. However in the future if you want a pool or a nice sized shed or something like that, the easement will cause a bit of trouble @1.5m it will affect your size + positioning + design. Also I don't know what the easement looks like but if you are into gardening and planting you also loose a bit of space if its like a concrete spoon drain or something, if its not a spoon drain you can then just plant over it or put a garden bed (not officially but unofficially). So I guess the decision is really just based off whether you'll ever need to use the back yard for other things, in this current age most people just go with the biggest house they can and the back yard barely has much left anyway, in which case the easement is negligible.

    Also regarding water run off to 136, once all the properties are built and landscaped this will be a negligible issue. Remember the adjacent houses will capture most of their rainwater in a gutter system which goes to a tank with an overflow, this is then connected to the main stormwater drainage system. So you really only concerned with their water run off from the remaining grassed area. Which will just mostly absorb into the grass, so its not much. Push come to shove, you can install a strip drain when you build the house where the grass in the back yard and the house meet, or you can install a footpath at the back of the house along the edge, then a strip drain, then your grass. But I doubt you will need to.

    Water run off is not the issue but cost of building a proper retaining wall that's aesthetically looking and long-lasting is one. Also you should consider lot with house slab above road level, not lower.
