Engineering report on river works




70

NELSON GOVERNMENT GAZETTE.

The order in which these works should be carried out, if not undertaken all at once, would be as follows, viz:—

  1. Curred groin on South Spit, which may cost when complete. Say 20 chains at £500 a chain ... ... £10,000 0 0

This is a work which may be done gradually, by devoting a portion only of this sum to it annually. It is marked A on plans.

  1. Stone training wall across shallow bay, on North bank where old snag lies, about 5 chains below Stanley Wharf. This is to regulate the curve. 7 chains, at £53 a chain ... ... ... £371 0 0

This is marked B on plans.

  1. Training wall or groin on tail of Spit. Say 17 chains, at £53 a chain ... ... ... £901 0 0

It is marked C on plans.

  1. Protection of river banks from action of surf, by covering them with stones between the stone groins. Say 17 chains, at £25 a chain ... ... ... £425 0 0

Marked D on plans.

  1. Same process carried downwards, along north bank of river, to preserve curve, to be done gradually. Say 15½ chains, at £53 a chain... £821 10 0

Marked E on plans.

I have made Mr. Dobson, Provincial Engineer, acquainted with the substance of this Report, with which, I may state, he fully concurs.

I am indebted to him for the preparation of the plans, and for much valuable evidence and information bearing on the subject, to which he has evidently given much careful observation.

I have, &c.,

JOHN BLACKETT,

Acting Engineer-in-Chief.

Printed under the authority of the Provincial Government of the Province of Nelson, by CHARLES ELLIOTT, Trafalgar-street, Nelson, Printer for the time being to the said Government.
