Cost to Develop Raw Land in Joshua Tree, CA

[Chris Frydenlund]

I'm looking at homesteads near Joshua Tree National Park in California. Listing agents say that the power is nearby (some say a mile away and some say 100 ft. away) and water is along the street. 

But what would it cost to hook up/connect to the utilities and get a septic system in this area? I have no experience with development of raw land, and this will be my first real estate purchase.

I know septic system varies a lot, which is why I'd like to know if anyone has experience with this in or near Joshua Tree, CA.
