When subdividing land, try to think of how the land naturally divides. It is simpler to market parcels of 5 acres each, but its an imposed order.
I do some larger scale designs and im looking holistically at the land and its energy flows, resources and ideal house sites. Then calculate that.
Because you may find it has many more ideal house sites and can sustain higher populations.
Perhaps some parcels are like a summer camp deal, you own it and come stay from spring till fall. This is good for the mobile people and matches the times of resource abundance.
Also designing the whole first can help you plan where damsites can be, where a long term timber forest could go that feeds a property development fund.
Smart communities look how to earn for the future to maintain infrastructure in 20 years time.

Hope that gives you some ideas
