• Select freeboard (minimal cost)  This would be the level above the flood plain as the new mark  for construction
•  
Revise floodplain maps and City’s floodplain regulation bylaw ($20,000)
•  
Install pump-test well/level gauges for Area AN to assess groundwater ($42,500)
•  
Prepare erosion hazard maps ($25,000)
•  
Install water-level gauges & develop winter flow monitoring program ($70,000)
•  
Develop ice-related flood forecast procedures and public notification policy ($20,000)
•  
Develop freshet forecasting procedures ($25,000)
•  
Monitor river bed at confluence ($15,000)
•  
Monitor future impacts on flood flows (minimal cost)
1. Area A

Enlarging the Cottonwood Island side-channel was identified as a beneficial project although it would not reduce Flood Construction Levels in the area. The project would be carried out  in 2 parts, with the first  part (mainly engineering) at an estimated cost of $390,000 and thesecond part (mainly construction) of $3.5 M.
