That is right on. I have an old book that talks about how to make
these. Basically you use a paper mache wrapper around some rough
gravel (similar to fish tank gravel) and the filler is potassium
chlorate and sulfur (60:40 as I recall) AKA fulminating powder
When the mixture gets ground up between the rough rocks it
"fulminates" (goes bang). You can also get this stuff to go off if you
hit it with a hammer or similar implement. I suspect it is also what
was in "caps" (as in cap gun). I guess you have to be old to know what
Too many different rules, regulations, involved utilities and land ownership
to be able to give advise via newsgroups. You really need to check with all
parties involved to find out where you stand in regards to liability,
responsibility and culpability.
True, especially erecting anything permanent. Meantime, I'd put a trashcan
on the corner, or a bucket with sand and a 2 x 4 sticking up. Anything that
is visible and not very damaging to a passing car it they do hit it. No one
will be injured. It may be just enough for drivers to be more careful and
2x4 might go thru someones windshield if they hit it.
Maybe one of those flexible white plastic pipes like the Highway Dept uses
on roadsides,that you can drive over and they just spring back,they have a
reflector or reflective finish on them.They don't damage your car(maybe
painted bumpers) if you drive over one,but will make a "thump".
They get used in turn lanes,to keep cars from being able to change back
into thru lanes after a certain point.
Or,you could "borrow" one of those highway "sawhorse" barriers with the
flashing light on top.... B-)
leave it on the corner like some construction work is ongoing.
another thought;put in some 1"x2"x4 foot stakes and wind some yellow
"danger" tape (like police use at crime scenes) around the stakes,make
people think there's some hole or repair work going on there.
I notice those same flexible pipes around town. Not sure, but it seems
like homeowners request them from the town. It doesn't seem like Public
Works drives around to scout out where install them. Becuase I see some
with one marker and another house with millions of them. There are plenty
of other places where the markers could be installed, but they aren't
buffalo ny: i own a corner rental house. here you are limited by
ordinance so you do not obstruct the motorists view even with your
landscaping or bushes back to specified distance from an intersection.
there are several different issues for you on this. there is a safety
hotline such as call before you dig in many areas. it looks like your
gas line is marked in yellow paint arrow. are both those pictured
service plates from the same company? especially if that is gas
service to your home i would ask them to have a routine look at it
with their gas leak sniffer and make any recommendations to the
company. if that second service plate is for a different utility or
water, give them a call too or have your plumber look at it. is that
the handicap wheelchair ramp to the sidewalk on the left? perhaps just
hire your concrete contractor to fix this, perhaps simply widening the
ramp and adjusting the curb cut a bit. the hidden damage underground
below the two service covers would be of concern as well. at my
property there was a sewer with a broken trap which they fixed when i
figured it out. a retired good neighbor here previously found
himself passing the time on his porch yelling at cars that don't come
to a complete stop at the stop sign nearby; but when our street was
closed due to construction for three months he learned to yell instead
at the squirrels raiding the bird feeder.
you might be obligated to put your municipality on written notice
about this problem since it's their street. and maybe get one of those
squirrelproof birdfeeders so you can laugh at the squirrels too.
