2. Ethics for Managing Storm Water
Doing the right and proper work action without anyone watching or knowing if payment will occur.
Doing our best to stay in permit compliance.

3. All projects have in common
Managing the Storm drainage
Where does the water go
Where are the inlets
Where are the ditches and culvert outfalls
Where are the slopes
Where are the exits
What are pollution generating operations
Inspecting for operational performance
Developing corrective actions
Implementing the corrective actions

4. Obtain the BIG picture Walk the site Google the site
Photograph the site, document pre-existing conditions
Identify the risky locations
Identify the risky operations
Develop site plans
Assign responsibility

5. What are the risky locations and operations?

9. Where/what are the risky locations?
Managing storm water tools for:
Drainage to wetlands, creeks, rivers, streams, lakes, judicial ditches, private property, off ROW

Protection of private/public areas
Working above public waters
Silty soils
Windy areas
Bottom of steep slopes
Drinking water wells
Infiltration/filtration basins

10. What/where are the risky operations?

What is required?

15. Site Management Plans Strategies for the work Materials for the work
Equipment for the work
People for the work
Timeline for the work
Contingencies for the work

16. Site Specific BMPs, but universal in implementation
Defend the perimeter
Defend the inlets
Defend the exits
Provide culvert end energy dissipation
Develop clean dewatering
Control the dusts
Stabilize the conveyances

Control dust generation
Prevent spills
Control waste materials
Inspect for function and performance
Upgrade to deliver cleanest water
