Springpole_GenericSedInstall_____________________________________________________10July2013 • How to install and monitor the control measures Installation 1. No digging, grubbing or ditching will occur within the flood plain or 30 m past the flood plain. 2. No debris will be dropped in the stream any debris that inadvertently falls into the stream will be removed. 3. Snow and ice will be removed from the work area. 4. The culvert installation will be in the wet for all cool water streams. 5. For those streams that are determined to be cool water (no in water work from September 15 to June1) culvert installation will be in the dry by using sand bag coffer dam as outlined in the MNR NEST Field Guide - Instream Sediment Control Techniques Field Implementation Manual and illustrated in outlined in Figure 2. 6. As required, silt fences constructed of staked geotextile will be placed along the road edges to keep material from entering the creek. The silt fences will be long enough to cover the work area i.e. excavator work area and stock pile area. The silt fences will be the standard width of a geotextile roll (1m). 7. Measurements downstream of water depth will be verified and the excavator will ensure the depth of the culvert will be 40% below this level. 8. The appropriate culvert for the crossing as outlined in Figure 1 will be installed 40% into the stream bed. 9. The grade of the culvert will reflect the grade of the natural stream bed. 10. If the stream bed is rocky the culvert will be placed on top of the rock/bedrock. 11. Erosion resistant gravel will be used to pack around the culvert as shown in Figure 3. 12. The excavator will back fill the gravel in 300mm layers and pack each layer before adding the next layer. Long Term Erosion control 1. A layer of coarse erosion resistant crushed granular B gravel will be used to cover and crown the road. 2. All slopes will be left at 2:1. 3. Acid free rip rap of various sizes will be used to stabilize the culvert ends as shown in Figure 3 Step 4 -5. Any exposed areas will be seeded with an approved seed mix and/or local organic material and vegetation. 4. As required diversion ditches or berms will be used to direct water into sediment settling structures (slash, settling holes, natural vegetation) Reclamation and Rehabilitation The following steps will occur: 1. The rip rap will be excavated and stockpiled on the road for use after the culvert removal. 2. All material used to cover the culvert will be removed and transported from the crossing site and spread along the existing road in a 20 cm deep layer. 3. The culvert will be removed and disposed of at a proper recycling centre. 4. Measurements of water depth will be taken up/down stream from the crossing. An average water depth will be calculated. 5. The stream bed at the crossing will be left at the average calculated depth. 6. The slopes from the stream will be pulled back and sloped at 2:1 or greater to minimize water erosion. 7. The rip rap will be used along the water edge to form a protective barrier 25 long by 1m wide and .20-.30 m deep. ______________________________________________________________3 of 11
