BACKGROUND 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14,

Over the last decade discussions have taken place between the City of Chico and stakeholders regarding all modes of travel on 2 nd Street corridor. 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, BACKGROUND

2 nd Street & CSUC Gateway The 2 nd Street Corridor supports large volumes of pedestrians, automobiles, busses, and bicycles, but currently has no designated lane for bicycles. 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, BACKGROUND

Level of Service Heavy left turn movements from 2 nd Street on to Main and Broadway cause traffic congestion and level of service deficiencies – a well known issue. 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, BACKGROUND

As a result of the recently developed Transit Center, ongoing discussions of promoting bicycling on 2 nd Street have continued A holistic look at the Downtown area is necessary, which opened the idea for the concept of converting the direction of traffic on 1 st Street and 2 nd Street to one-way traffic, creating a “couplet 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, BACKGROUND

PROPOSAL 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14,

The City is exploring modifications to the 1 st Street and 2 nd Street corridors with the goal of: – enhancing safety for all travel modes – promoting alternate modes of transportation – providing convenient additional parking – revitalizing the CBD without additional infrastructure improvements – converting to a ‘complete street’ 1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL Road Diet Four-lane to three-lane conversion (one lane in each direction with a center turn lane) On-street bicycle lanes in both directions

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL One-Way conversion Reduce to two through lanes On-street bicycle lane(s) Increase parking supply by converting parallel parking to diagonal parking

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL Roundabout Transition one-way to two-way traffic Provides enhanced capacity for east-west traffic Accommodates non-standard intersection alignment Gateway to downtown Increase safety for all modes of travel

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL One-Way conversion Reduce to two through lane(s) (one lane west of Broadway) On-street bicycle lanes Increase parking supply by converting parallel parking to diagonal parking

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL Drop-off Circle Ongoing coordination with CSUC Transition one-way to two-way traffic Allow for northbound U-Turn movement Provide for a gateway entry to CSUC

1 st Street and 2 nd Street Couplet Traffic Modification Project May 14, PROPOSAL Two-Way conversion One through lane in each direction Increase parking supply by converting parallel parking to diagonal parking Allow for more circulation options
