Section 451 of the Local Government Act 1974 states:
1) If any person proposes to erect any building or to carry out any work in such a location and at such levels that the diversion,
alteration, protection, or replacement of any drainage works of Council appears to be essential to the erection of the building or
carrying on of the work:
a) That person shall notify Council of his proposals; and
b) If Council is satisfied that it is practicable for its drainage works to be diverted, altered, protected, or replaced without material
interference with the services for which it is responsible and that it is reasonable that this can be done, it may enter into an
agreement with that person as to the manner in which the drainage works shall be diverted, altered, protected, or replaced.
2) The cost of so diverting, altering, protecting, or replacing the drainage works of Council shall be borne by that person, and all other cost.
3) If that person fails to comply with any condition specified in any such agreement, he commits an offence against this Act.
You will need to cover any costs to the Council of:
- CCTV condition surveys; and
- Changes to any easement documents, if necessary; and
- Memorandum of Encumbrance expense, if necessary; and
- Design and construction work to move or change the assets in any way.
