Triassic Posted July 14, 2019 Posted July 14, 2019 Reading the paper today I see that in some parts of coastal USA the latest mantra is elevation, elevation, elevation. Do you ever worry about climate change and it’s effect on your building location, construction style etc.
ToughButterCup Posted July 14, 2019 Posted July 14, 2019 Worry for myself, no. It's our grandchildren's experience that concerns me. Maybe, just maybe the house standard to which most of us on BH build will be more common when they think about self building?
ProDave Posted July 14, 2019 Posted July 14, 2019 At over 100 metres above sea level I won't get worried. But personally I would not even consider anything less than 10 metres ASL now.
PeterW Posted July 14, 2019 Posted July 14, 2019 Nice tool here that may help you make decisions http://www.floodmap.net/
Russell griffiths Posted July 14, 2019 Posted July 14, 2019 I find a lot of these new regulations ridiculous we are at 89m asl, but required a full flood risk survey, our house is built according to the findings in the report which are 700mm above ground level which is 1.2m above our lake level. If that lake was to rise 1m I would think 75% of the south east of England would be under water. Bloody ridiculous.
Thedreamer Posted July 14, 2019 Posted July 14, 2019 Not worried myself as we are 60 meters above sea level and our loch hasn't changed since the last ice age. The self builders constructing the passive house in Portree moved to Skye because of the environmental concerns. There is a video that runs about forty minutes regarding their decision. https://portreepassivhaus.uk/video-reports/
Simplysimon Posted July 14, 2019 Posted July 14, 2019 we were 7-10m asl in the previous house, going to be 90m when built, will be nice to have a house near the beach.

I am sinking at about the same rate. It is not so much the mean sea level, more to do with storm surges. We had one a few years back, it was quite interesting to watch it, the harbour visibly filled up (smashed boats too because of waves). Edited July 14, 2019 by SteamyTea
Thedreamer Posted July 14, 2019 Posted July 14, 2019 No not our Loch. Waterfall just increases in flow when water levels are higher. 2
SteamyTea Posted July 14, 2019 Posted July 14, 2019 7 minutes ago, Thedreamer said: No not our Loch The UK mainland is tilting about 3mm/year because of the last ice age, which pushed Scotland downwards. Then add in sea level rise because of ocean thermal expansion of about 3mm/year.

But I can see how it would be an issue to other coastal plots.

scottishjohn Posted July 14, 2019 Posted July 14, 2019 you would have no problem with SEPA --salmon cant run up that waterfall 1
Onoff Posted July 14, 2019 Posted July 14, 2019 120m asl here...but in the bottom of a valley! Posted before but the road at the bottom of my drive when it really rains:
Ferdinand Posted July 15, 2019 Posted July 15, 2019 About 175m here. Can sometimes be a bit windy, but not on a Scotland scale.

No, it's not tectonic movement as such, but the slow rebound from having the mass of ice removed from the end of the last ice age. In effect, Scotland is "floating" up very slowly, relative to the South of England. 1

The best case I know of is the sea "dock" of Harlech Castle, which since the 12C has grown room for a golf course on land that has appeared as a result of the spring-back. Are there any others eg new Islands in Scotland? F
