Browse Forums Building Standards; Getting It Right! 1 Nov 06, 2022 6:42 am A development site next to us has been recently completed, and we have been having issues with stormwater runoff, especially during heavy rain. These stormwater runoff issues have been caused by the following: 1. They used a waffle pad next door and in the process changed the level of the land by using lots of fill, so increased the level of their land on their side (we are on the lower side). 2. Their driveway that runs along our boundary has a stormwater pit in the middle of it, but we can tell by using a hose over the fence that the driveway slopes slightly to our site, rather than towards the drain in the middle. This is the only stormwater drainage provider in their front yard, which is where the problems are coming from. 3. The fill that they used next door appears to be some sort of clay (?) that is not very permeable (compared to the soil usually in our area). On top of this they have extensive paved areas in the front yard, and where they don’t they have used artificial grass with no drainage under it (the artificial grass was installed just on top of gravel). 4. They have recently installed a garden bed (as part of their landscaping) with soil piled against our boundary paling fence (it goes well over the plinth). We spoke to them about how this could cause issues and they nailed some bits of wood into part of the plinth (there was nothing else put into place to stop moisture coming through the soil and rotting the fence). I live in Victoria and I am aware of using VCAT for unreasonable flow of water situations (we have had damage to our property already, so I will need to seek compensation from VCAT anyway). However, with only a stormwater pit in the front yard (which is inadequate as not all water is being directed in it), is there anything Council can do (ie enforcement order) to make the owner put in more adequate stormwater drainage after construction is completed? I note that the National Construction Code talks about surface & subsurface drainage, but I find this confusing (I’m not too sure if non-compliance with this and/or AS/NZS 3500.3 could lead to Council issuing an enforcement order). Re: Stormwater Runoff from Adjoining Property 2Nov 06, 2022 6:24 pm Document the issue with photos and video before and after rainfall. Start now and maintain it for a number of rain periods. Go to council so they can document the issue and provide your records. It’ll be a long process but any property that dosnt contain its water runoff is non compliant. The NCC, AS and likely council requirements will dictate this Re: Stormwater Runoff from Adjoining Property 3Nov 06, 2022 8:28 pm Bimbob Document the issue with photos and video before and after rainfall.

I have been documenting during rainfall, but definitely not before (I had some photos of after). Thanks for the advice. Plumbers 'can be' plumbers, made all the worse by self certification which the building surveyor invariably accepts as proof of compliance! The good thing is that you know know. 3 5674 Grab a hose, insert it at the top of the inlet/down pipe and turn the water on and see where the water is escaping from. Then you'll know. 3 9137 in the stormwater pit or the drain? Those dont look like theyd fit in the drain. Separately, the pits do get stuff in them during the course of the build.
