The purpose of erosion control is to prevent sediment laden runoff from leaving the construction area at 'any time. Refer to NTCOG Item 3.12. 1.02 REFERENCED STANDARDS North Tens Council of Governments (NTCOG) - '~3eneral Specifications For Public Works Construction". TYPES OF EROSION CONTROL Straw Bale Dike The purpose of a straw bale dike is to intercept and detain small amounts of sediment laden nmoff from relatively small unprotected areas. This type of system can only be used in conjunction with other devices, such as a silt fence. It is not a "stand alone" option. Silt Fence A silt fence serves the purpose to intercept and detain water borne sediment from unprotected areas to a limited extent. Silt fences are the most common means of erosion control used. Triangular Sediment Filter Dike A triangular sediment filter dike intercepts and detains water borne sediment from unprotected areas of less than one acre. If the uphill slope above the dike ex~eds 10 percent, the length of slope above the dike should not exceed 50 feet without additional devices uphill. This device is effective on paved areas where instalhtion of a silt fence is not practical. Coppert 2 Meter Vault/94-81/2-6-97 02290 - 1 iT l' llll I EROSION CONTROL DURING CONSTRUCTION D. Stabilized Construction Entranc~ The purpose of constructing a temporary stabilized construction entrance is to prevent sediment from leaving the project site and becoming a nuisance on a paved street. Install a temporary stabilized construction entrance at any point where traffic will be entering or leaving' a construction site to a paved surface, thus reducing or eliminating the tracking or flowing of sediment onto the paved surface. E. Other Control Devices Diversion Dike: A temporary diversion dike is a barrier created by the placement of an earthen embankment to reroute the flow ofnmoffto an erosion control device or away from an open, easily eroch~le area. Interceptor Swale: A temporary interceptor swale iS excavated as required to shorten the length of exposed slope by intercepting runoff They can also serve as perimeter swales preventing off-site nmofffrom entering the disturbed area or prevent sediment laden runoff from leaving the construction site or disturbed area. Rock Betre: A rock berm is to serve as a check dam in areas of concentrated flow to intercept sediment laden nmoffl detain the sediment and release the water in sheet flow. Sand Bag Berm: A sand bag berm is to intercept sediment laden water from disturbed areas such as construction in stream beds, create a retention pond, detain sediment and release water in sheet flow. Stone Outlet Sediment Trap: A stone outlet sediment trap is an impoundment created by the placement of an earthen and stone embankment to prevent soil and sediment loss from the site. 'A sediment trap is to intercept sediment hden nmoff and trap the sediment in order to protect drainage ways, properties and rights of way below the sediment trap from sedimentat,on. A sediment trap is usually installed at points of discharge from disturbed areas. Pipe Outlet Sediment Basin: A temporary pipe outlet sediment basin is an impoundment created by the phcement of an earthen embankment and an integral pipe spillway structure for the purpose ofdewatering the impoundment as well as an emergency spillway structure for heavy flows. A sediment basin is to intercept sediment laden nmoff and trap the sediment in order to protect drainage ways, properties, and rights of way below the sediment basin from sedimentat, on. A sediment basin is usually installed at points of discharge from disturbed areas. Settling Tanks: A temporary tank is used to impound discharged water from an open trench or tunneling operation for settlement of sediment laden water prior to discharge into a storm water ditch or storm water system or Coppell 2 Meter Vault/94-81/2-6-97 02290-2 EROSION CONTROL DURING CONSTRUCTION PART 2 2.01 2.02 waterway. The sediment hden water must be held in the tank a minlnmm of two hours to allow settlement of the suspended particles. When sediment occupies 1/3 of the tank capacity it should be removed. Discharge mustbe through a filtered opening to reduce suspended sediment vohtme. PRODUCTS STRAW BALE DIKE Straw bales must weigh a minirnum of 50 pounds and be at least 30 inches in lengtk Use binding wire or nylon string and not jute or cotton binding Do not use bales for more than three months and rephce sooner if structural integrity is lost.

Anchor the bales in place by a minimum of two 2 inch x 2 inch wood stakes or steel '7" posts driven through the bales. EROSION CONTROL DURING 02290 - 3 CONSTRUCTION Installation on Pavement: Secure each bale in place by weights placed on the downstream side of the bale. Anchor all bales together to prevent individual movement of a single bale. Anchors may be made into the pavement only if approved by the Project Manager. This is restricted to areas where the pavement is to' be rephced as part of the same Contract. Make inspection weekly and after each major storm event. Repair or rephce promptly as needed. Remove bales when silt reaches a depth of 6 inches. B. Silt Fence Installation on Soft: Set posts a minimum of 1 foot deep and space not more than 6 feet on center. Cut a 6 inch wide trench 6 inches deep at the toe of the fence and backfill with earth or gravel Overhpp fabric a mininmm of 3 feet and join such that no leahie or bypass occurs. , Installation on Pavement: Weight fabric with rock on the upstream side to prevent flow from seeping under the fence. Make inspection weekly and after each major storm event. Repair or replace promptly as needed. Remove and dispose of silt when it reaches a depth of half the height of the fence. C. Triangular Sediment Filter Dike 1. Phce dikes in row with the ends tightly abutting the adjacent d~e. , Make inspections weekly and niger each major storm event. Repair or rephce promptly as needed.
