Cost estimates are important for prioritizing projects

• Excavation

• Pipe (bevel and polymer coating)

• Bedding and fill (including raised road elevation)

• Road surfacing

• Haul away old pipe and unusable fill

• Riprap, silt fence

• Dewatering / pumping

• Project administration and surveys

Key habitat advances:

a) Trimble Yuma

b) Roadsoft - management system

Next steps -

a) Model development- refine current model- new models (truncated, species)- decision based (remove vs.

remain)

b) Measure biological and habitat response
