Is cedar considered naturally decay resistant enough to be placed in contact with paved surfaces like at a front porch column, or must they be placed on a plinth block like non-treated pine?

Anytime you stand it on it's end grain it acts like a sponge. Pressure treasted or not.
Block is always a good idea.
As far as requirement. I would call you're local building dept for their take on it.

You should use one of these regardless of lumber type.

Is cedar considered naturally decay resistant ...

Depends.

Most cedar is not considered naturally decay resistant, but some is:
- From the 2006 IRC:
- - NATURALLY DURABLE WOOD. The heartwood of the following species: Decay-resistant redwood, cedars, black locust and black walnut.
- - - Note: Corner sapwood is permitted if 90 percent or more of the width of each side on which it occurs is heartwood.

For information on heartwood, go here:

BTW, that is one of 3 Douglas Fir posts and there were no splits or checks in any of them. I wanted to ask the builder how he seasoned them.
