Are there permanent mappable locations for such materials - materials 
purposefully set aside for a single purpose? 

I always think of sandbags as a make-shift solution, and sand as a generic 
building material. 

but if there is some permanent stockpile set aside for flood control in other 
countries, perhaps “flood_control_materials” is a good tag value.

Good idea. It would be nice if these stockpiles of materials could all be
tagged in a similar way. Piles of sand could also be used for flood control
(eg to fill sandbags), while minds gravel and rocks could be used to repair
roads, dikes, and so on.

BTW, I believe the British English term is “dike” instead of “levee”

Hmm - no one at that location repairs levees. It is a station just to store 
blocks. 

I just want it to be unambiguous. 

Like the difference between car repair and car parking

Even then, levee_repair might be good enough. 

I know there are gravel and salt (bunkers?) Along the sides of roads - I'll 
have to see how they are tagged.

Why not levee_repair?
Good to know they have a name and a list

I found a sign cycling today. 

奥戸防災ステーション

Okudo (village) "Disaster prevention station" 

The "river" is implied - "river disaster prevention station" is a huge 
mouthful. 

The government has a PDF listing of a hundred of them and their addresses. 
These might be the very large stations with a highground and a helipad, not 
just a cache of breakwater blocks and gravel. 

I will investigate further, but levee_breach_materials might be the most 
flexible for uses elsewhere.

I cannot find an official name or ref - but I can see their purpose. 

The next time I am on a cycling survey, I will take a picture of any small 
plaques they usually put somewhere on a man_made construction. 

I haven’t been able to find any sign onsite or web site explaining them - they 
are for someone with access to big (military) helicopters, so there is 
little-to-no public facing information at the sites themselves - but somewhere 
someone has a PDF with all the locations marked and ref'ed. 

I imagine it is not important to map them, but since I know what they are, I’d 
like to do it. 

All the signs tell people not to dump garbage, and one that says that the 
public parking lot is an emergency=assembly_point, but that is not present at 
the others - most are just stacks and stacks of blocks fenced in, waiting for a 
helicopter year after year. Some of the areas are very small - 100m2 - but the 
contents are just breakwater blocks surrounded by a fence, and they are stored 
adjacent to the levee - so there is only one purpose they could serve. you 
usually only see these kind of blocks near the ocean, protecting coastlines and 
and stacked into breakwaters.  

all of the permanent levee protection is poured concrete and boulders, so they 
are not normal building materials. 

I have found 15-20 caches of these blocks along the river in my area. Some are 
really old. The more I look, the more I find. I imagine there are several 
hundred Just around Tokyo. 

there are very few things that can stop a levee breach:

Levee_breach_materials is a mouthful, but I cannot think of a shorter way to 
make the tag descriptive enough to avoid mistagging.

Do these have anything to identify them, like a ref?
3 words for a key seems like a mouthful to me, maybe 
emergency=levee_repair/materials.

[Tagging] Emergency=levee_breach_materials

[John Willis]

I ran into an interesting thing when mapping my local rivers. 

All of the rivers in my area have levees running 100% of their length from the 
mountains to the coast, there are probably over 1000 linear KM of earthen 
levees in the Tokyo region alone - 20mx10m levees (or bigger) along the outer 
banks of all rivers. 

the small and the large rivers in my area have emergency levee repair stations 
- hundreds of 1000kg concrete breakwater blocks (like you would see in the 
ocean), a helicopter pad, and access to dirt/gravel. 

https://www.openstreetmap.org/way/550873664 


They are situated on high ground, above flooding. 

After I found one, I found other collections of emergency breakwater supplies 
along my river, and there are others along the larger rivers. 

I have never seen one of these purpose-built stations before. 

I am unsure of the landuse of such a station, nor is there a good tag for it. 

I thought up Emergency=levee_breach_materials

Thoughts?
