[TowerTalk] Ground question

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

2. What gauge solid copper wire.  

Where we live in Western Oregon does not get much lightening. My antenna will be 10-12 ft. Above the highest point of the roof. 

Thanks for the help.
