Project Scoping

Public Outreach and Agency Coordination

Bulk mailing to 45,000 residents and businesses E‐mail and social media blast to 4,000 additional parties Received 115 responses providing 203 comments Comments and questions fell into 3 main categories:

  • Construction (time, lighting, utilities, vibration etc.)
  • Minimizing project footprint/duration
  • Environmental impacts (noise, water, erosion, wildlife,

and recreation including Little Jamaica)

Potential Environmental Consequences and Mitigation

Visual and Scenic Quality

BLM visual resource management classifications

Minor to moderate changes to the landscape allowed

New bridge would use similar style, scale as current bridge

Key Study Components and Results

Draft EA Summary and Findings

Undertook public and agency scoping Developed and refined purpose and need Evaluated design and access alternatives Coordinated with land management and regulatory agencies Documented potential environmental effects

‐ Mostly temporary in nature

‐ Would be minimized through mitigation measures
