Site Evaluation & Parameters
Common Existing Site Conditions:
1. Undersized Culvert/Bridge (span)
2. Minimum Rise or Cover
3. Narrow Roadway Width
4. No Head or Wing Walls
5. Damage from Flood(s)
6. Existing Culvert(s) have Detiorated
Invert(s)
7. Roadway Closure - Limited or Not
Practical
8. Rural Location w/Limited Access
Site Evaluation & Parameters
Common New Project Conditions:
1. Limited $$$$$$
2. Permitting & Engineering Required
3. New Culvert/Structure Larger both Span & Length
4. Bottomless (Footings)
5. New Headwalls
6. Water Quality (acidic?)
7. Flood or Wetland Boundaries
8. Aquatic Life “Friendly”

Choosing the Best Plate Product
Project Info to Begin Reviewing Culvert Option(s):
1. Waterway Area (SF)
2. Minimum Span (Ft)
3. Available Rise/Height (Ft)
4. Bottomless
5. Water or Soil “Ph”
6. Surface or Highway Loadings
7. Inlet/Outlet Ends
8. Assembly
Choosing the Best Plate Product FIRST – Grab Resources to Assist in the Process

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):
1. Waterway Area (SF)
- Different Size & Shapes
2. Minimum Span (Ft)
- Min or Choose Larger Span?
Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):
3. Available Rise/Height (Ft)
- Option to “Raise” Road for Structure Value
Engineering (Arch, Arch Pipe, Ellipse)?
Low Profile/Rise

Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):
4. Bottomless
-Full Invert or “Natural Stream Bottom”?
-Abrasion Concern?
5. Water or Soil “Ph” (Stream/Wetland)
-Near “Neutral” or More “Acidic”?
-Structure Backfill Typically Neutral
Rules of Thumb
50 yrs for STEEL
75 yrs for ALUMINUM
Typically Invert Governs Service Life
Choosing the Best Plate Product Project Info to Begin Reviewing Culvert Option(s):
6. Cover or Traffic Loadings (H25)
-Anything Unusual?
7. Inlet/Outlet Ends
-Variety of Options
