Upon completion, the site shall be reinstated and other measures which are not required shall be removed, unless otherwise stated. The best management practices for erosion control include, but not limited to the following. a) Earth bank/perimeter dike: A temporary berm, dike, embankment or ridge of compacted soil. located in such a manner as to intercept, divert and channel water to a desired location to reduce potential erosion and off-site sedimentation. b) Diversion: A channel of compacted soil constructed above, across or below a slope with a supporting earthen ridge on the lower side to reduce the erosion of steep or highly erodible areas or to convey water through a construction site. c) Lined waterway (rock materials): A waterway or outlet with a lining of rock, stone or other permanent material to provide for the disposal of concentrated runoff, where grassed waterways would be inadequate due to high velocities. d) Catch drain: A drain running along the side of a road or track to collect runoff from road/track surface. e) Cascading drain: Concrete stepped catch drains laid on the steep terraced slopes to guide flows from the berm drains down to catch drains at the base.

JKR/SIRIM 3:2020 © JKR and SIRIM Berhad 2020 - All rights reserved 33 f) Riprap: A layer of medium rock laid onto slopes and channel beds to protect soil from erosion in areas of concentrated runoff. g) Check dam: A small, temporary device constructed of rock, sandbags or fiber rolls, placed across a natural or man-made channel or drainage ditch to reduce the velocity of concentrated stormwater flows, to trap small amounts of sediment generated in the conveyances, to reduce scour and channel erosion and to encourage sediment dropout. The check dams shall be inspected regularly after rain and any damages shall be rectified. The sediment accumulated behind the check dams shall be removed when it has reached two-thirds of its height and disposed at designated site. h) Temporary interceptor dike: A ridge of compacted soil, often accompanied by a ditch or swale with a vegetated lining, located at the top or base of a sloping disturbed area to limit the flow accumulation of erosive volume of water. i) Swales: Temporary or permanent channel, which may be linked with natural vegetation, synthetic materials or rock to slowly convey runoff to a discharge point. j) Temporary and permanent pipe slope drain: A temporary or permanent heavyduty flexible pipe or conduit structure placed from the top of a slope to the bottom of a slope to convey storm water runoff down the face of a cut or fill slope. k) Rock outlet protection: Paved and/or riprapped channel treatment, placed below storm drain outlets or any discharge outlets to reduce storm water velocity and to prevent scour at storm water outlets. l) Sandbag barrier: A temporary linear sediment barrier consisting of stacked sandbags placed around site perimeter, along streams and channels, below the toe or down slope and erodible slopes, around stockpiles, etc., to intercept and slow the flow of sediment-laden surface runoff. Sediment should be removed when the sediment accumulation reaches one-third of the barrier height and disposed at designated site. m) Storm drain inlet protection: Silt fence, sandbag or fiber rolls installed around any storm drain inlet to reduce stormwater velocity and detain or filter sediment-laden runoff. n) Silt fence: Temporary sediment barrier made of non-woven, synthetic filtration fabric stretched across and parallel to the contours of the site, attached to supporting wood or steel posts and entrenched, to prevent sediment carried by sheet flow from leaving the site by slowing storm water runoff and causing the deposition of sediment at the structure. The silt fence shall be inspected after every rain event. The silt accumulated behind the fence shall be removed when it has reached two-thirds of the fence filter height and disposed at designated site.

Upon completion, the site shall be reinstated, including landscaping, and erosion control item and other measures which are not required shall be removed, unless otherwise stated. The best management practices for erosion control include, but not limited to the following. a) Mulching: Application of residues such as grass clippings, leaves, hay, straw, shredded bark, sawdust, wood chips, shredded newspaper, cardboard and wool; to protect soil surface from raindrop impact for reducing the velocity of runoff and to foster the growth of vegetation for providing insulation against extreme heat. b) Revegetation (turfing): Establishment of temporary vegetation cover with fast growing species on disturbed or denuded land to reduce storm water runoff velocity and maintain sheet flow and to promote infiltration of runoff into soil. c) Hydroseeding/hydromulching: Mechanical method with forced water of applying seed, fertiliser and mulch to exposed land in one step in order to revegetate. d) Riprap slope protection: A layer of medium rocks placed on slopes or streambanks to improve the stability of soil slopes. e) Protective blanket/erosion control blanket/soil stabilisation mat: Use of the biodegradable blanket or mat on steep slopes, channels or streambanks to protect soil and hold seed and mulch in place so that vegetation can become well established. f) Surface roughening: Use of mechanised equipment to roughen the soil on a bare slope with grooves or terraces that run perpendicular to the direction of the slope to loosen compacted soil that has been cleared and graded, cut or filled; to create small grooves or terraces which can reduce runoff velocity and trap seed, fertilisers and sediment; and to provide more favourable conditions for vegetation establishment. g) Creepers: Creepers planted through either seeds or saplings into a planter bed previously prepared with drainage layer/weep holes and topsoil. Creepers should be planted individually directly at the toe of wall/slopes at approximately 0.3 m centre to centre. Commonly used creepers are of the species Centrosema pubescens, Ficuspumila and Parthenocissus himalayana. Ficuspumila and Parthenocissus himalayana are suitable on concrete/gunited slopes and rock surfaces. 4.2.1.4 Sediment Control BMPs The project proponent/contractor shall install appropriate sediment control measures prior to commencement of any earthwork and shall be maintained throughout the construction period to ensure the effectiveness.
