Should I use type L or type M, from what I read the M should be sufficient unless it's outside or buried? Can I mix the two such as L for my outside riser and M for the crawl space?

You need to be the judge of the potential for damage too the riser from planter excavation, lawn tools etc.

I would use "L", sched 80 PVC or for the potential of sever damage, "K".

I wouldn't transition to "M" until the first fitting inside the dwelling.

L, M & K just require a little adjustment to the learning curve when soldering.

do not use M use only L
M is thinner walled than L , L will last years longer

use 1'' pvc from your meter to your crawl space, then a 1x3/4 male adapter, install a valve
then run your copper

Any reason of using the pvc for the riser? If I install the valve in the crawl space I have about a 20 ft belly crawl to shut off the water to the house. There is a valve in the meter box but I was going to install a valve before it goes thru the stucco siding into the crawl space. I was going to do a copper riser with ball valve, there is already pvc from meter to riser(which currently is galvanized).
