Marlborough Sounds Resource Management Plan 2 October 2014 36.1.3.4.2.5.2 Vibration Vibration from a site due to blasting shall not exceed a peak particle velocity of 5mm per second provided this level may be exceeded on up to 5% of the total number of blasts over a period of 12 months. The level shall not exceed 10mm per second at any time. 36.1.3.4.2.6 Vibration Inside Buildings Vibration from a site measured inside any dwelling in any zone shall not exceed a peak particle velocity of 0.1 metres per second. 36.1.5 Land Disturbance Any land disturbance activity which meets the conditions below is a Permitted Activity. 36.1.5.1 General Conditions a) Any increase in the concentration of suspended sediment shall not be more than 20% as measured by the ‘black disk’ method, notwithstanding that the concentration of suspended sediment in run-off water shall not exceed 200 grams/ cubic metre at any point of discharge to any receiving water. The effects on the receiving water are to be measured at a distance downstream of two widths of the receiving watercourse or 50 metres, whichever is the lesser; b) No woody material of greater than 100mm diameter shall be left in any permanently flowing river, lake, wetland or sea as a result of a land disturbance operation; and c) All land disturbance sites are to be stable when subject to a storm event of return frequency probability of 10% or less. 36.1.5.1.1 Exception Except any land disturbance activity that does not comply with the above conditions or is in an area identified as a hazard area that is required for the purposes of constructing or providing access to any structure requiring a building permit under the Building Act 1991, shall not be a Permitted Activity, with no restriction on the exercise of Council’s discretion. 36.1.5.2 Cultivation 36.1.5.2.1 Contour Cultivation Cultivation is to be parallel to the contour of the land, with the exception that on lands of slope greater than 20°, up to 15% of the cultivated area may be cultivated at an angle to the contour, and trenching or cable laying may be carried out at an angle to the contour. 36.1.5.2.2 Riparian Management Zones No cultivation is to take place within riparian management zones as specified in the schedule of water bodies and Table 1 in Appendix I and as mapped in Ecology Maps in Volume Three Maps, except trenching for cable laying and post holes for utility line support structures. 36 - 6
