Just What Do We Do?
Natural Resources Conservation Service (NRCS)
Help conserve our natural resources:
– Soil
– Water
– Plant
– Animals
– Air
Helping People Help the Land
• Assist Private Landowners & Producers
• Assist Local, State and Federal Agencies
• Assist other local groups of people
NRCS Engineering
• NRCS State Engineering Staff - Indianapolis– State Conservation Engineer (requires a PE)
– Agricultural Engineer
– Civil Engineer
NRCS Engineering
• 4 Area Engineers – Located at Vincennes,
North Vernon, Lafayette, and Fort Wayne
• 8 Technical Team Engineers – Mainly Ag & Civil
Engineers
• 1 Project Engineer
NRCS Engineering
Design• Hydrology (rainfall and runoff)
• Hydraulics (pipe flow, weir flow, channel flow)
• Soils/Soil Mechanics (permeability, bearing strength)
• Structural (timber, concrete, rock)

NRCS EngineeringGrassed Waterways – Design
Steps:
Drainage Area
Capacity (Use 10yr-24hr storm)
Grade (from survey)
Depth/Width/Velocity
Typical velocity range is 1.5 fps to 3.0 fps
Use Erosion Control Blanket above 3.0 fps
Excel Design Program on NRCS website
Grassed Waterway
NRCS EngineeringGrade Stabilization
Structures– Design Steps:
Drainage Area
Capacity – varies with drainage area and overfall
Overfall (from survey)
Type of structure must be determined based on capacity and overfall
NRCS EngineeringTypes of Grade Stabilization
Structures:
Drop Toewall (wood, reinforced concrete, aluminum)
Pipe Drop
Straight Pipe
Rock Chute
NRCS EngineeringWater & Sediment Control
Basins- Design Steps:
Drainage Area
Volume to be stored (runoff from 10yr-24hr storm)
Stage-Storage (from topographic survey)
Levee height
Subsurface drain, riser, and orifice (based on drawdown time of 24 hours)
3
NRCS EngineeringTerrace - Design Steps:
Spacing (slope, equipment)
Type of TerraceFarmed or Grassed
Drainage Area-between terraces
Channel Grade (velocity)
Levee height
Outlet (grassed waterway or tile outlet)
NRCS Engineering
Wetland Restoration/Ponds Design Steps:
Drainage Area
Soils (will it hold water?)
Stage-Storage (from topographic survey)
Levee height
Levee top width/sideslopes
Principal Spillway
Emergency Spillway
Wetland RestorationWetland Restoration
Goose Pond4,400 acres water

NRCS Engineering
Stream bank Stabilization Design Steps:
Drainage Area
Capacity of stream
Soils (stable slopes)
Grade (from survey)
Velocity in the channel
Size armoring materials based on velocities

Emergency Watershed Protection (EWP)
• EWP Program – Protect lives & property threatened by natural disasters• Floods, Tornadoes, Hurricanes, Wildfires, Earthquakes
• Protecting Infrastructure: Roads, Bridges, Homes, Utilities– Must benefit more than one property owner
• Majority Assistance: Debris removal from streams, Stabilize stream banks, Repair Conservation Practices
• Other Assistance:Dams and Levees
