KEY CONSIDERATIONS
• Different types of waterpower
• Construction can have negative impacts
• Opportunities are best identified early in the planning process
• Clear demarcation of boundaries
• Maintain hydrological balance
• Mitigation must consider wetland type and sensitivity
SPECIFIC MITIGATION - PROTECTION
• Hydrogeological study
• Minimize soil compaction
• Seasonally timed
• Appropriate erosion control
• Roads (location, maintenance)
• Wildlife
• Invasive species
• Sod mats
• Culverts
• Placement of fill
MIGRATORY BIRDS - MITIGATION
• Avoidance timing for clearing, de-watering and flooding
• Dust control
• Directional lighting
• Speed limits
• Exclusion fencing
• Noise control
