Hi John,
To appraise the assets you're asking about, you'd need to hire both personal property and real property appraisers. To appraise everything, regardless of the appraisal's intended use, you'd likely need to utilize sales comparison, cost, and possibly income producing valuations approaches depending upon how you utilize your outdoor spaces. I can't answer much more without knowing the specifics of your need. That being said, it may not be necessary to appraise all the items you've listed above depending, of course, on the intended use of the appraisal.
