In supporting information, the application said the Sanders family had exclusive possession of the property, which is on Crown pastoral lease land, and rights of trespass against the public.
Matangi Station already had tracks, fences and stiles as well as routes established by a mountain bike group and these attributes had resulted in growing public recreational use of the station.
Out-of-town commercial operators had been using the station without permission and dogs had been taken on to the station without consent, posing a serious risk of sheep measles.
Members of the public had also damaged gates and locks and fences.
Tracks had been damaged by unauthorised motorbike use and "the situation has grown to be somewhat out of control", the applicants said.
In background information, the Sanders family said the project would require significant work and oversight on their part and needed to be undertaken on a commercial basis.
It was proposed that new tracks be constructed, and existing ones improved.
Signs would be installed, ongoing track maintenance established, a car park built, toilets and drinking water provided and a further three stiles that had already been built, installed.
Electronic stiles might also be required in the future "to encourage users to pay".
An additional stile might be required in Graveyard Gully Rd as well as a further five stiles at high-usage crossing points in conjunction with new tracks.
Aspects of the activity would require land-use consent, for instance, the commercial activity; sight distances from intersections; anticipated traffic movement of more than 15 vehicles a day; the establishment of a car park to cater for events (capped at 25 per year); and the fact that one of the proposed stiles would be in Graveyard Gully Rd, an outstanding natural feature area.
An area of Matangi Station on the riverside of Tuckers Hill Rd would be available for walkers and mountain bikers use without charge.
The Sanders family requested that the application be publicly notified under the Resources Management Act 1991.
People had until Thursday, September 9 to make comment to Matangi MTB Park Ltd, 1054 Little Valley Rd, Alexandra or to the Central Otago District Council.
A council spokesman said while the application was publicly notified before lockdown, potentially the time could be extended and the council would consider any requests for late submissions providing they had valid reasons.
A notified consent normally took three months to process without delays for requests for further information and/or the applicant putting the application on hold.
