2016 INTRODUCTION, For FY17 training the City will focus on the top 11 BMP deficiencies and develop contractor. training sheets that can be used in a monthly stormwater training conducted by the. contractor,SEDIMENT CONTROL,SE 1 Silt Fence,SE 6 Gravel Bag Berm. SE 10 Storm Drain Inlet Protection,SE 16 Compost Socks and Berms. TRACKING CONTROL,TR 1 Stabilized Construction Entrance Exit. NON STORM WATER MANAGEMENT,NS 10 Vehicle and Equipment Maintenance.
WASTE MANAGEMENT,WM 1 Material Delivery and Storage. WM 3 Stockpile Management,WM 4 Spill Prevention Control. WM 5 Solid Waste Management,WM 8 Concrete Waste Management. Page 2 of 3 Staff Training,2016 INTRODUCTION,LEVERAGING DATA. The City will follow the process described below to leverage the data that it is collecting The. top 11 deficiencies that will be selected with the 12th being this introduction sheet The intent. is for the contractor to provide this training to his staff on a monthly basis similar to the more. frequent safety training This may also satisfy the contractors NPDES permit requirement for. providing and documenting training,FUTURE TRAINING.
If you would like to be notified when the next version of this training comes available please. take our survey and place your name on our email list The survey can be taken at the following. Page 3 of 3 Staff Training,2016 Silt Fence,Sediment Control SE 1. Exposed and erodible slopes small cleared areas,Streams and channels. Temporary stockpiles and spoil areas,Limitations, Not in concentrated flow areas in streams channels drain inlets. Not where ponding 1 5 may occur and where ponding may cause flooding. Max slope length 200, Not below slopes subject to creeping slumping or moving areas. Not for diverting flow,Follow level contour,Implementation.
Max slope perpendicular to fence 1 1 Horizontal Vertical. Leave horizontal space for runoff to pond behind fence 3 ft if possible. Turn ends of fence uphill to contain runoff, Leave undisturbed area immediately downhill from fence if possible. Use commercial quality posts appropriate filter fabric 1 75 long and 15 gauge. staples for posts and 9 gauge wire for fastening posts together. Installation, Dig 6 deep by 6 wide trench fold fabric into trench on uphill side of fence. Drive posts into downhill side of fence fabric,Posts 6 apart 12 18 below trench. Make sure fabric is on side of fence facing slope,Secure fabric to posts. Fence ends wrap fabric around two posts one full turn secure with 4 staples or wire. Extra strength secure plastic or wire mesh support between fabric and posts. To link fences together wrap fabric around each fence end join posts and roll them. together secure tops with wire,Backfill trenches with compacted material.
Page 1 of 3 Staff Training,2016 Silt Fence, Along perimeter Fabric wrapped Trenched Fasten fabric to. around post in ground concrete using slats,Maintenance and Removal. Remove sediment when at 1 3 height of fence,Replace when worn torn or damaged. Retrench or replace if not properly anchored in ground. Remove silt fence once slope surface is permanently stabilized. Inspection,Inspect prior to during and after rain events. Inspect weekly during the rainy season, Sediment 1 3 H Ponding behind fence Fence should be located next to curb.
fences not joined Water depth exceeds fence height. Page 2 of 3 Staff Training,2016 Silt Fence,Project Name. Project Location,Instructor s Name s,Instructor s Title s. Course Location,Print Name First Last Signature Date. Page 3 of 3 Staff Training,2016 Street Sweeping Vacuuming. Sediment Control SE 07, The roadway gutter is part of the City s storm drain system Therefore any project dirt.
or sediment should not have made its way to the storm drain system. If possible located project exits far from City storm drain catch basin or inlets. Limitations, Sweeping and vacuuming may not be effective when the sediment is wet or when. tracked soil is caked,The caked soil may need to be scraped off. Implementation, When possible designate a separate entrance exit to the project site Provide signage. Sweep or vacuum self propelled walk behind shop vac on a daily basis. Do not use kick broom attachments mounted to a backhoe This tends to spread dirt. rather than remove it Use a street sweeper with a vacuum. Page 1 of 3 Staff Training,2016 Street Sweeping Vacuuming. Soil tracking onto City street Soil tracking beyond project entrance. Sweep surface when tracking occurs On roads use a sweeper w vacuum. Maintenance and Removal, Persistent staining of the road surface should not have occurred if upstream BMPs were.
Maintain or replace upstream BMPs,Provide additional upstream BMPs. Inspection,Inspect road daily for sediment tracking. If tracking observed inspect tracking control entrance TR 1.

Page 3 of 3 Staff Training,2016 Inlet Protection,Sediment Control SE 10. Storm drain inlets receiving sediment laden runoff. Limitations,Drainage area 1 acre, Requires adequate area for ponding without intruding on roadways with traffic. Requires two types of BMPs to protect inlet,Implementation Installation. Need to identify appropriate inlet protection design based on. o Location and extent of ponding,o Possibility of runoff diversions. 5 common inlet protection devices,1 Filter Fabric Silt Fence.
For drainage basin 5 slope with sheet flow 0 5 cfs. Grading complete soil seed stabilization pending Not for paved areas. Installation,6 wide x 6 deep trench, Place stakes or capped rebars 3 ft apart drive 18 in into ground. Stakes rebars should be 48 in, Lay fabric upside of trench then up stakes Max fence height 24 in. Secure with heavy duty wire staples or wire 1 in length. Internally brace vertical stakes to anticipate flow. 2 Excavated Drop Inlet Sediment Trap,Installation,Clear area of vegetation grade. Excavate area around the inlet to trap sediment, Concentrated flow 2 1 L W shape length oriented toward flow. 3 Gravel Sand Bag, Use upstream of inlets on gently sloping paved streets.
Sheet concentrated flow 0 5 cfs,Short term use not for roads open to traffic. Installation, Use geotextile fabric bag not burlap with 0 75 rock or 0 25 pea gravel. Leave room upstream for water to pond, Use several layers of sand bags overlap pack tightly. Leave gap of one bag on top to serve as spillway,Ensure storm water does not overtop curb. High clay silt areas use filter fabric gravel as additional filter. Page 1 of 3 Staff Training,2016 Inlet Protection,4 Block and Gravel Filters.
Barrier using concrete blocks and gravel,Flow 0 5 cfs. Not for use within vehicle and pedestrian traffic areas. Installation,Surround storm drain with cinder blocks. Cover all cinderblock openings with filter fabric or wire mesh. Surround the cinder block barrier that is facing away from the storm. drain with gravel or filter sock, If necessary place 2 x4 wood beams through block openings for extra. 5 Temporary Geotextile Insert proprietary,Refer to manufacturer instructions. Inspection and Maintenance, Before after forecasted rain during extended rain events weekly during rainy season.
Flash flood warnings advisories perform maintenance on all site BMPs remove inlet protection. reinstall when warnings advisories are over, Replace silt fence when clogged torn or degraded stakes secure and in good shape. Gravel filters Clean or replace if gravel becomes clogged with sediment. Inspect gravel bags and replace as needed ensure bags are properly placed. Remove sediment when at 1 3 barrier height, Remove inlet protection once area is stabilized clean and regrade clean storm drain. Block and gravel filter Inlet protected by two BMPs Gravel bags covering inlet. improper sediment control, Improper sediment control Inlet protected by two BMPs Improper sediment control.
