My backyard is north-facing and has a very slight slope to it (slopes away from house).
Its fenced and there are a row of cedars planted in a raised bed in the back of the yard against the fence.

The yard is a soggy mess in winter and in summer never completely dries out.
How do I add drainage to it?

My neighbor had similar problems - what he did was bought some PCP piping and a grate. He dug a trench where it is soggy the most out to the side of the house (going with the slight grade of the land). He then put the grate where it was really soggy about an inch below the ground, laid the pcp pipping and then covered everything except the grate with fresh dirt and grass seed. He did this about 5 years ago and seems to be working. Landscaping to help divert the water flow helps as well.
