The report basically says that your soil has a high percentage of gravel or fine stones and slopes from "a little bit" to "you know you are climbing". You will hit bedrock in as little as three feet in places. It drains very well (the gravely component) and will not retain moisture without adding organic material. The good news is that flooding shouldn't be a problem.
The portion that is considered Mounthope loam (parcel 669) seems to be an ideal place to begin permaculture efforts. It has the most organic material in the soil and will require the least amount of mulch, compost, etc. to start.
