Structures Protect Structural Integrity & Prevent Flooding Culverts Green Girl LDS

Structures Protect Structural Integrity & Prevent Flooding Culvert Green Girl LDS

Structures Dos and Don’ts Do’s Do remove sediment, debris & trash from inlet & outlet structures such as curb cuts, rip rap, sumps & grates. Do control and handle the removed sediment so it won’t get back into the storm system. Do prevent excessive ponding by inspecting underdrains. Do prevent flooding by clearing outlets of obstructions. Do protect the integrity of structures such as curbs, & walls. Do inspect less durable materials more often.

Structures Dos and Don’ts Do inspect culverts to look for UV degradation, cross-section shape changes that may cause flooding, and corrosion.

Erosion Prevention Erosion prevention is any practice that protects the soil surface and prevents the soil particles from being detached by rainfall or wind. Green Girl LDS

Erosion Prevention Cover Soils with Fabrics Green Girl LDS

Soil Quality Protection Limit Compaction Green Girl LDS

Sediment (aka Source) Control “Sediment Control is any practice that traps the soil particles after they have been detached and moved by wind or water”…

Sediment (aka Source) Control …to prevent this! Photo excerpted from “ODEQ Erosion and Sediment Control Manual”, DEQ, Apr 2005

Sediment Control for Concentrated Flows Inlet Filters Green Girl LDS

Sediment Control for Concentrated Flows Protecting Catch Basin Inlets Green Girl LDS OR DEQ

Erosion Prevention & Sediment Control Dos and Don’ts Do’s Do prevent erosion by keeping soil covered and getting plants established. Do prevent erosion by staying out landscape areas when possible. This also prevents soil compaction, which slowly kills vegetation and creates erosion long-term. Do control sediment when erosion cannot be prevented by using wattles & filter sacks.

Spills OR Department of Environmental Quality

Clean up the spill Do Determine what type of material has spilled Block stormwater inlets Use absorbent material to contain the spill Remove contaminated soil from facility Protective gear for workers OR Department of Environmental Quality

Clean up the spill Don’t: Dispose of hazardous material in the garbage. Must be taken to a hazardous waste facility. morguefile

Notify the appropriate authorities Do Contact owner of the facility Contact local jurisdiction emergency response Contact OR Emergency Response Photo: morgueFile

Spills Do Document the spill in the O&M report

Take Home Messages These recommendations are general guidelines Check with the local jurisdiction for specific requirements Operations and Maintenance guidance document being developed for our region For more information, contact:
