activity involving the erection of a structure or structures which:

(i) are solid (or present a significant barrier to water or sediment movement); and

(ii) when established on the foreshore or seabed would extend 300 metres or more in length more or less parallel to the line of mean high water springs (including separate structures which total 300 metres or more contiguous);

is a restricted coastal activity.

S1.4 Structures in the coastal marine area oblique or perpendicular to mean high water springs

(a) Any activity involving the erection of a structure or structures:

(i) which is solid (or present a significant barrier to water or sediment movement), and is sited obliquely or perpendicular in horizontal projection to the line of mean high water springs in the coastal marine area, and is in horizontal projection less than 100 metres; or

(ii) which is a submarine or sub-aqueous cable;

is not a restricted coastal activity.

(b) Any activity involving the erection of a structure or structures:

(i) which is solid (or presents a significant barrier to water or sediment movement);

(ii) which is sited obliquely or perpendicular to the line of mean high water springs in the coastal marine area;

(iii) which in horizontal projection is not more than 1000 metres in length;

(iv) which is specified in the relevant operative or proposed regional coastal plan as a discretionary activity; and

(v) for which the plan defines, or provides the criteria for determining:

• where it would be permissible to locate any such structure or structures;

• the materials to be used in their construction; and

• specifies the activities for which such structure or structures can be used; and

(vi) for which the plan:

• requires consideration of the likely adverse effects of the structure or structures; and

• defines, or provides the criteria for determining, the limits on adverse effects of the structure or structures;

is not a restricted coastal activity.

(c) Except as provided for in S1.4(a) and (b) above, any activity which includes erecting a structure or structures in the coastal marine area which is:

(i) solid (or presents a significant barrier to water or sediment movement);

(ii) is sited obliquely or perpendicular in horizontal projection to the line of mean high water springs in the coastal marine area; and

(iii) is in horizontal projection 100 metres or more in length;

is a restricted coastal activity.

S1.5 Structures in the coastal marine area used in the petroleum and chemical industry

(a) Any activity involving the erection of structures for the storage or containment of any petroleum, petroleum products, or contaminants in quantities less than or equal to 50,000 litres is not a restricted coastal activity.

(b) Any activity involving the erection of structures for the storage or containment of any petroleum, petroleum products, or contaminants in quantities less than 100,000 litres and more than 50,000 litres and the relevant operative or proposed regional coastal plan specifies that the activity is a discretionary activity and defines, or provides criteria determining:

(i) where it would be permissible to locate any such structures; and

(ii) the effects of the structure;

is not a restricted coastal activity.

(c) Except as provided for in S1.5(a) and (b) above, any activity involving the erection of structures for the storage or containment of any petroleum, petroleum products, or contaminants, in quantities greater than 50,000 litres is a restricted coastal activity.

S1.6 Disturbance of foreshore and seabed (excavate, drill, move, tunnel etc) including any removal of sand, shell or shingle

(a) Any activity involving, in any 12-month period, disturbance of foreshore and seabed for specific purposes, including any removal of sand, shell or shingle or other material which is either:

(i) maintenance dredging;

(ii) in volumes less than or equal to 50,000 cubic metres; and extracted from areas less than 4 hectares; and extending less than 1000 metres over foreshore and seabed; or

(iii) in volumes less than 300,000 cubic metres; and extracted from areas of less than 10 hectares; and extending less than 10,000 metres over foreshore and seabed; and

• is specified in an operative or proposed regional coastal plan as a discretionary activity; and

• the plan defines or provides the criteria which specifies the location where the removal can be carried out; and

• specifies when the activity can be undertaken; and

• specifies conditions to control any adverse effects of any removal or disturbance;

is not a restricted coastal activity.

(b) Except as in S1.6(a) above any activity involving, in any 12 month period, disturbance of foreshore and seabed for specific purposes, including any removal of sand, shell or shingle:

(i) in volumes greater than 50,000 cubic metres;

(ii) extracted from areas equal to or greater than 4 hectares; or

(iii) extending 1000 metres or more over foreshore and seabed;

is a restricted coastal activity.

For the purposes of this clause, maintenance dredging means any dredging of the bed of the sea necessary to maintain water depths to previously approved levels, for the safe and convenient navigation of vessels, in navigation channels and at berthing and mooring facilities, including marina developments.

S1.7 Depositing substances in the coastal marine area

(a) Any activity involving the depositing of any material on the foreshore and seabed which involves quantities less than or equal to 50,000 cubic metres at a site in the coastal marine area in any 12 month period is not a restricted coastal activity.
