2ND STREET CORRIDOR

Supports large volumes of pedestrians, automobiles, busses and bicycles but is busses and bicycles, but is mostly auto-oriented:

• No designated lane for bicyclesg y

• Some pedestrian and transit enhancements

Road DietF l h l i ( l i h • Four-lane to three-lane conversion (one lane in each direction with a center turn lane)

• On-street bicycle lanes in both directions

26

One-Way conversion• Reduce to two through lanes• On-street bicycle lane(s)• Increase parking supply by converting parallel

k d l kparking to diagonal parking

27

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

EAST 2ND STREET CROSS-SECTION

31

Drop-off Circle• Ongoing coordination with CSUC• Transition one-way to two-way traffic• Allow for northbound U-Turn movement

P d f CSUC• Provide for a gateway entry to CSUC

32

Two-Way conversion• One through lane in each direction• Increase parking supply by converting parallel

parking to diagonal parkingAll f l • Allow for more circulation options

33

Diagonal Parking• Increase parking supply by converting parallel parking to diagonal parking

34

Roundabout• Transition one-way to two-way traffic• Provides enhanced capacity for east-west traffic• Accommodates non-standard intersection alignment• Gateway to downtown

I f f ll d f l• Increase safety for all modes of travel

– Safety

– Shorter queuing distance

– Slower speeds for bicyclists

– Gateway opportunities

– Reduction in GHG

– Reduction in Fuel Consumption

CHICO - TRAFFIC OPERATIONS

Balance LOS and volumes along the 1st Street and 2nd Street Corridors

Maintain acceptable LOS at all intersection

Comparable or improved corridor travel time

46

CHICO - PEDESTRIAN FACILITIES

Crossing enhancements– Intersection bulbouts

Decreased pedestrian crossing distanceIncreases pedestrian visibilityp y

– Road DietFewer lanes to cross (less exposure area)

– Intersection improvementsPedestrian push buttonsPedestrian push buttonsAdditional signal walk-time for pedestrian crossingInstallation of count-down pedestrian signal headsADA upgrades

CHICO - BICYCLE FACILITIES

East-West Corridor Bicycle LanesImproved connections to CSUC and the Annie’s Glen trailColored bicycle lanesColored bicycle lanes

48

CHICO - TRAFFIC CALMING

Lane Reduction– Provides for slower, but steady progression of traffic

Diagonal Parking– Narrows the street encouraging slower driving– Narrows the street encouraging slower driving

Roundabout– Steady flow of traffic at a controlled speed

49

CHICO - ONE-WAY COUPLET

Utilize existing pavement to balance LOS and volumes without additional new infrastructure

Reduced conflicts with turning vehiclesg

Will provide space for on-street bicycle lane(s)

Allows for replacing some parallel parking with diagonal parking

Improved traffic flow

50

CHICO - ROAD DIET

Reduced conflicts with turning vehicles

Slower, but steady flow of traffic

Sh rted edestrian cr ssin distanceShorted pedestrian crossing distance

Allows for installation of bicycle lane(s)

Generally more comfortable for bicyclists and pedestriansGenerally more comfortable for bicyclists and pedestrians

51

1ST STREET/2ND STREET/FLUME STREET ROUNDABOUT

Reduced vehicle conflicts

Steady flow of traffic at a controlled speed

Sh rted edestrian cr ssin distanceShorted pedestrian crossing distance

Improved transition for two-way to one-way traffic

Creates a downtown gatewayCreates a downtown gateway

52

CHICO - DIAGONAL PARKING

Narrows street and provides traffic calming benefits

Goal of increasing parking supply approximately 25% from parallel parking

– Offsets loss where parallel parking is removed

53

A “COMPLETE STREET” APPROACH
