Each unit is individually metered for power and water. 

PRELIM LAND PLANNING- do a preliminary layout, please remember stream buffers, specimen trees, ANY jurisdictional waters (its a good idea to have you county water systems guy come walk your property with you to verify any jurisdictional water systems and what the required state and county buffers are for those systems).

Water/sewer is shared and can be sub-metered. 

My extensive real estate experience consists of 1 flip.I have an idea and I'd like to test the waters here in the forums.

So if your big into water sports, living in the desert could have all the profit in the world but it's going to be miserable hell and odd's are after some months the profits wont matter.

Rake the leaves, mow the lawn, and water the plants.

Sell and start fresh. 

If separate water line services for each unit weren't part of your original scope of service, then they are justified in asking for additional payment to redo the plans.

I think that this is the "blood in the water" thing that investors talk about. - The examples have incredibly good math on paper.

Other campsites are truly primitive with no amenities at all in terms of water/power/sewer.
