Recommended Option for Hyperion Ave

• The Recommended Option offers flexibility of converting to other

roadway options if the transportation conditions warrant it in the

future.

• The daily low count of pedestrians on Hyperion Ave would not warrant

sidewalks on both sides by reducing one traffic lane at this time.

• An ADA-compliant sidewalk will be implemented on the west side of

Hyperion Ave.

• Designated bike lanes will be implemented on Hyperion Ave.

• The Recommended Option, which most closely resembles Exhibit 1, is to

maintain the original 4-lane configuration of the circulated IS/MND, as

modified to include: (1) addition of bicycle lanes to Hyperion Ave, and (2)

elimination of a continuous, concrete median barrier.

• These project revisions do not create new significant impacts and do not

change effectiveness of mitigation measures, thus no recirculation of the

2013 IS/WIND is required for approval of the Recommended Option.

• The 2013 IS/MND did not include an alternative with three vehicle lanes.

Approval of such an alternative would require additional CEQA review (at

minimum revision and recirculation of an IS/MND and if any potentially

significant impact could not be mitigated to less than significant, an

Environmental Impact Report would be required).

• Additionally, since the close of the public review period, over 400

comments, petitions, and survey results have also been received and

considered by City staff. No new environmental impacts that have not

already been addressed were included.

Focus on the Overall Project • This $50 million project is predominantly funded by the Federal

Highway Bridge Program, State Proposition 1B, and Metro Call for Projects.

• Many years of collaboration with Caltrans/FHWA, along with support of

elected officials and community groups, to receive funding on the

following components that are typically not part of a bridge

improvement project:

• 1-5 Realignment

• Bike access from northbound Glendale BI to LA River Bike Path

• Pedestrian bridge across the LA River

• Infiltration Basin

• Further delays in completing the design of the project will jeopardize

the overall project. 1111111
