1 Continuing Education Associated with Maintaining CPESC and CESSWI Certification Module 2: Stormwater Management Principles for Earth Disturbing Activities Sponsors: ODOTs Local Technical Assistance Program (LTAP)/ODOT November March 2013
2 Agenda: Stormwater Management Principles for Earth Disturbing Activities What is Stormwater? Erosion and Sedimentation Other Stormwater Pollutants Associated With Construction Activities Erosion and Sediment Control Practices Discussion 2
3 WHAT IS STORMWATER? STORMWATER Is precipitation runoff, snow melt, surface runoff and drainage. 3
4 Natural drainage systems use, delay and drain stormwater. Rainstorm swales, rills, channels, streams roughness, storage (in floodplains) Flow Rate (Discharge) Typical Hydrograph (storm water runoff graph) for Undeveloped areas Drain Use Delay infiltration, evapotranspiration Time 4
5 Historically, ODOT treated stormwater as a hazard, to be disposed quickly... Rainstorm Conveyance/Drainage Only We have become real good at this! Drain Flow Rate (Discharge) Undeveloped Use Delay Time 5
6 ... but caused downstream flooding. Next, detention was used to reduce peaks... Rainstorm Conveyance/Drainage Only Flow Rate (Discharge) Undeveloped Drain Use Delay Peak Flow Control (delay) via detention techniques Time 6
7 ... but did not solve flooding watershed-wide. Stream Flow Pre-development Post-development Increased Downstream Flooding 7
8 More detention further reduced peaks... Flow Rate (Discharge) Rainstorm Conveyance/Drainage Only Undeveloped Further Reduced Peak Flow/Delay Control = Increase in cost What s Next: 1. This solved the flooding issues but not erosion and water quality 2. This lead EPA to regulate water quality of storm water discharges 3. Controls to restore natural hydrology, removed volume, but where not feasible. 4. May result in extended detention to address volume/flow issues Time 8
9 Stormwater Management Principles for Earth Disturbing Activities EROSION AND SEDIMENTATION 9
10 Erosion and Sedimentation What is Erosion? Erosion is the process that by actions of wind or water, soil particles are detached and transported. 10
11 Erosion and Sedimentation Factors that Influence Erosion Topography Vegetation Hydrologic Soil Groups Climate Precipitation, Wind Land use Impervious cover 11
12 Erosion and Sedimentation Types of Erosion Splash Erosion Raindrop impact energy is enough to dislodge surface sediments. Source: 12
13 Erosion and Sedimentation Types of Erosion Sheet Erosion Sheet erosion is caused by rain splash detaching soil particles, lifting them up and removing them by shallow sheets of water flowing down a sloped soil surface. Sheet Erosion concentrates to form rill erosion 13
14 Erosion and Sedimentation Types of Erosion Rill Erosion As flow concentrates, small channels begin to form in the soil surface. 14
15 Erosion and Sedimentation Types of Erosion Rill Erosion to Gully Erosion 15
16 Erosion and Sedimentation Types of Erosion Gully Erosion Gullies are formed when runoff cuts rills deeper and wider or when flows from several rills come together and form a large channel. 16
17 Erosion and Sedimentation Types of Erosion Channel Erosion Channels may become unstable due to increased flows or changes in upstream sediment load. 17
18 Stormwater Control Strategies Erosion vs. Sediment Control Looking at different Erosion and Sediment Control BMPs. Understanding which BMPs to be used for what you are trying to control 22
19 Erosion and Sedimentation Erosion causes Sedimentation Erosion Sedimentation 23
20 Erosion and Sedimentation What is Sediment? Sediment is eroded material suspended in wind or water. 24
21 Erosion and Sedimentation What is Sedimentation Sedimentation is the deposition of eroded material. 25
22 Erosion and Sedimentation Impacts of Sedimentation Deposited on adjoining property and roadways, affects health, safety, and welfare. Fills storm inlets, storm sewers, and detention basins, reducing their capacity and increasing maintenance. Smothers benthic habitat / life, disrupting aquatic ecosystems. Others????? 26
23 Let s Take a Look at Other Impacts 27
24 Let s Take a Look at Other Impacts 28
25 Other Stormwater Pollutants Associated with Construction Activities Dewatering Discharges Dewatering is now a permitted activity under the CGP Dewatering discharge can no longer be directly discharged to storm systems or receiving waters. 29
26 Other Stormwater Pollutants Associated with Construction Activities Construction Materials, Wastes and Storage Proper handling, clean up, disposal, and management of construction materials and debris is important! 26
27 Other Stormwater Pollutants Associated with Construction Activities Spills These examples are not all inclusive. As the SWPPP designer or CESSWI inspector these pollutants shall be addressed as part of the SWPPP plan and documented/identified during inspection. 27
28 Stormwater Management Principles for Earth Disturbing Activities EROSION AND SEDIMENT CONTROL PRACTICES 28
29 Erosion and Sediment Control Practices Minimize Areas of Disturbance and take advantage of Erosion Controls 1. Identify existing conditions and natural resources. 2. Plan project to minimize footprint / impacts to resources. 3. Delineate existing / proposed drainage areas. 4. Determine limits of grading and clearing. 5. Sequence and/or phase construction activities (i.e., underground, at grade and vertical). 29
30 Erosion and Sediment Control Practices: Protecting the Perimeter Buffers Sediment barriers At limits of construction and surrounding resources to protect Street Sweeping Construction Entrance Points of ingress / egress 30
31 Erosion and Sediment Control Practices: Internal and External Controls Berm Bypass Run-on at construction limits Culvert Photo of open channel Internal drainage and protection Slope Protection 31
32 Erosion and Sediment Control Practices: Implement Erosion and Sediment Controls Photo of silt fence Photo of straw bale barrier (or sand bag barrier??) Photo of waddle?? Sediment Fence Inlet Protection Sediment Controls Temporary Sediment Basin/Trap Ditch Check Construction Entrance Erosion Controls Slope Drains 32
33 Erosion and Sediment Control Practices: Manage Construction Materials / Wastes Photo of Stockpile / Borrow area Photo of Concrete / Asphalt plant Photo of Waste Dumpsters / trucks On-site / Off-site Staging/Borrow/Waste Areas Photo of Dewatering Photo of Concrete waste disposal Photo of Equipment leaks / maintenance Active Construction Areas 33
34 Erosion and Sediment Control Practices: What s the Purpose? Effective erosion controls MUST: Prevent the dislodging of soil particles Effective sediment controls MUST: Prevent sediment from leaving the site Pond runoff Release it slowly Erosion Controls Sediment Controls Seeding and Mulching Slope Drains Dikes/Berms Construction Entrance Sediment Dam Sediment Basin Rock Channel Protection Ditch Check Channel Protection Inlet Protection Filter Fabric 34
35 Erosion and Sediment Control Practices: Internal Project Drainage Concentrated Flow So, this is what really happens when it rains! 35
36 Erosion and Sediment Control Practices: Implement Controls Appropriately Contractors need to understand: Intent of control How to use appropriately ODNR Rainwater & Land Development Manual Version 6 One example for appropriate use of sediment control (Silt Fence) Only for small upslope drainage area / flow path length 36
37 Erosion and Sediment Control Practices: Implement Controls Appropriately 37
38 Erosion and Sediment Control Practices: Before You Leave 1. Temporarily stabilize site when earthdisturbance suspended: - Winter - Rainy / high flow conditions - Construction phasing considerations 2. Use proper method for postconstruction conditions: - Seed - Mulch 3. Check effectiveness and maintain / replace as needed Mats / steep slopes Concentrated flows 4. Remove temporary controls 38
39 Erosion and Sediment Control Principles Group Discussion on the following: EVALUATION 1. Erosion Control Practices that are working and effective Name them and why they are working well. 2. Sediment Control Practices that are working and effective Name them and why they are working well. 3. Run off Control Practices that are working and effective Name them and why they are working well.
