It is considered prime agricultural land.
Hundreds of acres of Kunia farmland are now coming under scrutiny.
In the past five years, the lots have been snatched up for everything from raising chickens to horses.
But a cultural watchdog group points to what it says are 60 cultural sites including a heiau, and burial mounds that the state has identified in the area.
There are at least two dozen that have been designated for preservation according to Wahine O Kunia.
"These are ancient sites we have been trying to make aware of its significance and its not to be touched," said Sheila Valdez.
Wahine O Kunia has been knocking on doors trying to get some agency to check on reports that bones were unearthed during construction in the area.
"It was brought to our attention that bones were found and dug up while they were doing the infrastructure of the area and according to specific people the bones were hidden after they were dug it up," said Valdez.
But the state office charged with historic preservation says it hasn't been able get access to check out the complaints.
"We have been trying for months , quite literally months, to get some federal agency, or state agency or county agency to step up and say this is ourresponsibility, our kuleana, but and so far we haven't got there, and we keep asking, and trying to find out what's going on and if something is going on find on solution. We have not been able to get our foot through the door," said Alan Downer, administrator of the State Historic Preservation Division.
A security guard is now posted checking the ID's of everyone who comes in to the area.
And Valdez said she and staff members of a federal agency were denied access recently.
"In the beginning the developers said they would do what's pono and they would do everything they can. It’s even in their conservation plan that they would save all, no matter how small saved, but nobody's been watching and there's a lot of destruction," said Valdez.
There is also a separate issue of illegal structures that have sprung up.
The city says in the last two months it has issued 17 notices of violation to property owners who have been structures larger than what is permitted.
Homes are not allowed here but the inspectors have not seen allowed inside to see if anyone is actually living there.
Property owners must correct the violations or face a potential fine.
The city says it has issued five notices to that effect.
The farm lots are not hooked up to city sewer or water lines.
Calls to the manager of the farm lots were not returned.
