Alright, I'll start out with the circumstances. Its late spring, and zombies are officially declared a threat, but their capabilities are still under speculation, and people are told to stay indoors. The local stores are being barricaded by their owners, people are driving to their loved ones, big towns like Seattle nearby are being largely affected and the hospitals are teeming with injured people, infected or not. Government is in control but losing it rapidly.

First off: We gather all supplies that we decided prior to this encounter.
In our flatbed trucks(already owned):
I bring the cement, medical supplies, planting equipment, and seeds. I'm an amateur botanist, but I can keep vegies alive.
My friends, 3 with flatbed trucks, but in total 35 people bring:
Wood, radios, cooking supplies, pumps, generators, cleaning supplies, and tools.
Everyone brings anything else that will help, survival manuals, water, food, binoculars, tents, and rifles. (most resources are not detailed in this plan)

We drive east for about 20 minutes until we reach a small area of unoccupied forest, about 25 sq. miles of mostly trails. We camp out near a pretty fast moving river, using our vehicles as a perimeter and set up camp. We've got 2 guys scanning for movement in the forest, weapons at the ready. One guy preparing food, the others performing normal tasks to keep the camp maintained.
And we do this for one week to decide how the situation goes.
If it gets worse, we head up to a easier to defend camp up north about 2 hours from the current camp. If it gets better, we either hole up for a few more weeks in the same spot or return back home depending on the situation.

If zombies are still a threat, we move up said camp.

Defenses: We build a barrier from one side of the valley to the other, nothing spectacular, about a foot high, just enough to be noticeable to a person who is looking for it, and set a minefield past that with improvised mines, the barrier is to distinguish between farmland and the minefield. We'll have three camps of two snipers in tree stands looking for any undead on the perimeter of the camp.

Food: We use the seeds to build a farm, able to feed more people then we need it to.
Maybe livestock if we are lucky to come across something that can be domesticated. We have guys on manual water filtering pumps, to keep a flow of fresh water.

Power: Obtained by hand cranked, bicycle, or gas generator, mostly dependent on available resources.

Living Space: A christian retreat I used to volunteer at. We will keep most of the living space, it has plenty of recreation rooms, and a place to store and keep firewood dry. Last minute defense of putting holes in the roofs to escape to if a large horde happens to stumble by, very unlikely, but possible, so we can stay up their, away from the horde and pick away until its safe.

Communication: Just a shortwave radio, for listening to any radio chatter from the government and surrounding installations.

We keep the facility maintained until winter when, with the decreased zombie speed will lower their combat efficiency and therefore, realizing an opportunity the remnants of the government will stand up and unite an offense to retake cities for knowledge, technology, weapons, and just resources in general. Even if the government won't stand up, retaking areas like, roads for metal off of cars during the zombie's most weakest point is essential.
