NC Land – The Challenges: Landslides

Mountain lots afford spectacular views. The trick is keeping your house where you built it.

From the above web site.

Now, we won’t be building on a debris fan like this apartment developer did. But will we be building in that yellow-bordered area? That’s no fun either.

To determine our fate, and if we should build, or cut our losses, the State of North Carolina, after 5 people were killed in a landslide in Macon County in 2004, (https://files.nc.gov/ncdeq/Energy%20Mineral%20and%20Land%20Resources/Geological%20Survey/Landslide_reports/SEFOP_07_PksCrk_Guidebook_Final_R1.pdf ) ordered “landslide maps” to be created for 19 high risk counties in the state.

Four counties got maps before the NC legislature pulled the plug on the project, apparently due to howls from the real estate industry about lost sales from the information on the maps.

Caveat emptor!

Our home site(tm) is perched on a ridge, so as long as nobody removes dirt/rock from the base of the mountain, and as long as we don’t overload the land with water from sprinklers, driveway runoff, septic tank fields, or experience torrential rains, we should be okay.

Needless to say, we will be visiting the roads downhill from us, looking for old debris fans. We are also consulting the excellent maps for our county, one of the lucky four counties to get maps, though oddly, not available on the county’s web site anymore.

It appears our property is not in a risk area, but there’s a mountain west of us that is, and the debris field will run through the valley below us (which has houses and a church or two.)

The other option being we walk away from this and find some nice flat land without views. That seems to be the wiser thing to do. Not that I’m prone to wise decisions.
