Two words - electric fence. My former boss is an awesome suburban gardener. That's how he manages veggies.

Voles and other burrowers need something like 1/2 inch mesh hardware cloth, buried 1 foot deep with a reverse L extending outward, away from the garden about 1 foot. Raccoons and Squirrels can and will climb any fence you put up, but if the planting beds are small enough so you can put a cover over (like a 4 x 4 bed) you can keep them out. Around many of the beds (4 x 4) I have made a frame that has fence fabric stapled to it that keeps out all the critters. With the frame the fence is easy to move off the planting bed for any work and maintenance necessary.

Hi I had a problem much like yours a few years ago, including two legged critters, What I did was to was to start by building several raised beds of various sizes then surrounding it with cattle panels supported by steel stakes. I Wired the first two feet of the panels with chicken wire and heavy plastic tarp. I wired the pannels to the stakes so that they were over 8ft. tall and even put a pannel top over half of it. I put in two gates that I kept locked and ran several electric wires to it so that most of it so it would keep almost everything out. That worked real well. I paid about $20 for each pannel and bought 10 of them and the stakes were about $8 for each stake. Lots of times you can get them at yard sales for half the price, the pannels will last for ever. I think that the chicken wire was $10 for a role of it. you can even add lights and noise makers or alarms. I found that it will keep just about everything out except Bears and sometimes even them.
