What you using for material?

Redwood.

One way to help w/ water accumulation is to not use wide material
for the treads -- instead of a single tread or 2x6-size material,
use 2x4 and leave gap between them.

True, but that strikes me as too informal for a front porch, better
for a rear deck.

If using 2x or 5/4 decking material, be sure to orient individual
boards so end grain direction is downward. This will ensure what
cupping does occur will be such as to not be upward but downward,
also helping to shed water.

I've heard that, too, but I believe it's a myth. See
