Why are you burying the radials? Their length has to do with the
frequency you're using. They don't necessarily have to be straight.

I am putting in a fairly short tower in my backyard; 35ft of Rohn 25g.
I will have 3 ground rods around the base. The tower is next to my house so
my ground radial field will be semi-circular.
I will be putting 8 ft ground rods every 16 ft. My lot is about 35 ft. deep
so radials will be 32 ft. Long buried about 16 in. Underground.
1. How many radials do I need and
Why do you need all these radials for a 35 foot tower? Are you going to be using it as a vertical? Then your question would be germane. If it's for lightning (that's LIGHTNING), it's overkill IMO.
Oregon only gets about 5 lightning days per year - not very significant. One ground wire per leg is fine - you pick the length. If it was my tower, I wouldn't bother.
Get the N0AX lightning book and read it. Methinks you're mixing up a lightning ground and an RF ground.
