Help deciphering a soil survey, please!

I've been trying to decipher my soil report, and haven't had much luck with my limited knowledge of these matters.

Here's a link to our areas soil survey: http://soildatamart.nrcs.usda.gov/Manuscripts/CA612/0/Butte_CA.pdf

We have soil areas 669 and 670 on the property.

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.

Does that help at all?

That is exactly what I wanted to know

Thank you very much Lolly k!
