<p>When starting your <a href="https://www.thebalance.com/construction-4074036" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">construction project</a>, control the limits of your project by working only in the necessary areas involved in the site. Controlling the areas to be worked is a great tip and will <strong>reduce significantly the erosion and sediment control problems</strong>. Keep natural vegetation when possible and do not disturb areas that have topsoil in place.</p>Control erosion and sedimentation by <strong>dividing your project into phases</strong>. When you divide your project into phases the erosion and sedimentation problem can be minimized and centralized in relatively small areas easier to control and to stabilize.<p>Runoff water can be redirected to specific areas where you will prepare a sediment trap or similar structure to trap sediment-filled runoff water. It can be controlled by redirecting water with diversion ditches located at the up-slope side of a construction site.</p><p>Many permits require you to carry out <a href="https://www.thebalance.com/rockfall-protection-systems-844576" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">stabilization measures</a> in place after a specific time frame. Some temporary measures can include: seeding, mulch, blankets, and the use of wool binders. If the stabilization measure is permanent it can vary from permanent seeding, planting, <a href="https://www.thebalance.com/how-to-control-erosion-on-a-construction-site-844573" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="2">channel stabilization</a> and green buffer. After the permanent stabilization measure is in place, you can go to your SWPPP to <strong>mark the area as completed and stop inspections</strong> in that area. Remember that dust control is also another area that needs to be stabilized.</p>There are multiple options for erosion and sediment control on slopes.<strong>Slope erosion control methods will depend on the degree of inclination of the slope being worked out</strong>. On a moderate slope active measures such as silt fence or fiber rolls can be installed on leveled contours between 10 or 20 feet in distance. Geo-textiles, turf blanket and mats can also be used as slope protection.<p>Usually storm inlets are protected inside a project but, not so frequent on adjacent or nearby storm <a href="https://www.thebalance.com/expert-tips-on-how-to-install-a-french-drain-drain-tile-845026" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">drain</a> inlets. Providing protection against erosion and sediment control on a storm drain inlet can be achieved by using silt fence, rock-filled bags, or block and gravel. The type of measure used will depend on the type of drain inlet being protected, it&#39;s opening and the flow that it is expected to receive.</p>An important tip when solving erosion control and sediment problem is to establish and secure a clean perimeter. A clean perimeter will be formed by installing a temporary silt fence barrier properly installed and trenched into the ground providing lateral resistance. This perimeter fence will retain sediment carried by storm-water, only in small areas and will be useless on large areas or high slopes.<strong> Do Not Use silt fencing or fiber rolls alone in areas that drain more than a quarter-acre per 100 feet of fence</strong><p>Many of the problems related to sediment and erosion can be reduced by <strong>building sediment control traps or basins</strong>. The installation of these systems will reduce runoff water allowing sediment to settle before it is discharged. EPA is enforcing a sediment basin on most of the construction projects to work as a sediment trap and to reduce the amount of energy being discharged into water systems.The sediment basin must the have capacity to store at least a two year <a href="https://www.thebalance.com/protect-construction-site-assets-in-stormy-weather-844482" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">storm</a> runoff water. <strong><a href="https://www.thebalance.com/what-is-dewatering-844520" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="2">Dewatering</a> practices are used to remove ground water</strong> or accumulated rain water from excavated areas and sometimes a separate permit is required to perform <a href="https://www.thebalance.com/what-is-dewatering-844520" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="3">dewatering</a> activities.</p><p>Stabilized construction entrances will help you to reduce sediment being carried away by construction vehicles. It is recommended to have two construction entrances, formed regularly by large <a href="http://geology.about.com/library/bl/images/blroadmetal.htm" data-component="link" data-source="inlineLink" data-type="externalLink" data-ordinal="1" rel="nofollow">crushed stone</a> areas. These areas will require maintenance or removing the crushed stone allowing for new and clean stone to replace the sediment-filled previous one.<strong>Construction entrance shall be at least 50 feet long</strong>. However, in some circumstances this length cannot be achieved, so it is recommended to provide on employee who can pressure-wash the tires of vehicles going in and out of the project.</p>Inspection is the key when working with sediment and erosion problems. Follow closely your plan, and inspect carefully your project after a storm event, or just after a small rainfall. By conducting small routine inspections your system will be able to handle in a more appropriate way run-off water.
