Bridge types for the Final EIS

 Importance of bridge type discussion

 Assess bridge impacts in the Biological Assessment and Final

EIS document

 Comply with US Coast Guard (USCG) navigational requirements  Determine project cost estimate

 Bridge type needed for Final EIS analysis  Bridge design details decided upon post-Final EIS,

including:

 Aesthetic elements such as lighting, railings, facade treatments  Aesthetic bridge and street connections into the neighborhood
