Living Streets Vision •  Equity •  For people of all ages and

physical abili/es whether they walk, bicycle, ride transit, or drive

•  Integrate connec/vity and traffic calming with pedestrian-‐oriented site and building design

•  Connect people •  Local people design their

streets

•  Are invi/ng •  Foster healthy commerce •  Strengthen and enhance

neighborhoods •  Encourage ac/ve and

healthy lifestyles •  Integrate environmental

stewardship •  Vary in character by

neighborhood, density, and func/on

Traveled Way Design

Design Principles

•  Accommodate all users

•  Design for appropriate speed in context

•  Safety

Access Management

Cross Sec;onal Elements

•  On-‐street parking •  Bicycle facili/es •  Transit facili/es •  Travel lanes •  Medians •  Turn lanes

Intersec;on Design

Principles of Good Intersec;on Design

•  Compact •  Avoid conflicts •  Simple right-‐angle intersec/ons are best

•  Avoid free-‐flowing movements

•  Apply access management principles

•  Signal /ming considers all users

Universal Access

Sidewalk Zones Single-‐Family Residen;al

Pedestrian Crossings

Principles of Pedestrian Crossings •  Safe crossing is a must •  Consider all users •  Meet accessibility

standards and guidelines. •  Crossings must be

“comfortable” •  Use treatments with

highest crash reduc/on factors

•  Don’t compromise safety to accommodate traffic flow

•  Design begins with appropriate speed. In general, urban arterials should be designed to a maximum of 30 mph or 35 mph

•  Every crossing needs tailored design

Design Considera;ons •  Ideally, uncontrolled crossing

distances should be no more than 21 feet. Streets wider than 40 feet should be divided by installing a median or two crossing islands.

•  Maximum of three lanes per direc/on on all roads (plus a median or center turn lane).

•  There must be a safe, convenient crossing at every transit stop.

•  Double (or triple) le` or right turns concurrent (permissive) with pedestrian crossings at signalized intersec/ons must never be allowed.

•  Avoid concurrent movements of motor vehicles and people at signalized intersec/ons.

•  People should never have to wait more than 90 seconds to cross at signalized intersec/ons.

•  Pedestrian signals should be provided at all signalized crossings where pedestrians are allowed.

Traffic Calming

Framework/Non-‐Framework Streets Use Cross-‐Sec;onal Measures

•  Reduc/on in # of lanes •  Reduc/on in lane width •  Medians, islands •  On-‐street parking •  Street trees •  Bike lanes •  Colored or textured

pavement •  Shared space •  Pedestrian-‐scale ligh/ng •  Curbless medians and

streets

Non-‐Framework (& Framework at low ADT) Streets Use Periodic Measures

Horizontal Measures

•  Roundabouts •  Mini-‐roundabouts

and mini-‐circles

•  Chicanes •  Impellers

•  Short medians

Ver/cal Measures

•  Raised crosswalks and intersec/ons

•  Speed cushions •  Speed tables •  Speed humps

Narrowings

•  Yield streets •  Bulb-‐outs •  Pinch points

Streetscape Ecosystem

Goals of Streetwater Management

•  Reduce runoff •  Slow flow •  Spread flow •  Sink •  Store •  Use

Street Trees

Street Furniture •  Benches and sea/ng •  Bollards •  Street vendor stands •  Informa/onal kiosks •  News racks •  Parking meters •  Signs •  Refuse receptacles •  Public art •  Sidewalk dining •  Clocks, fountains, etc.

Re-‐Placing Streets

Designing Land Use Along Living Streets

Design Principles •  Compact, connected, complete, con/nuous •  Organize places at a human scale •  Safety, convenience, comfort for all users •  Create places for people to interact; plazas, parks, squares •  Well connected street network of small blocks •  Locate land uses within walking distance of one another •  Buildings should face the street, have windows looking onto

the street and open to the sidewalk •  On-‐street parking provides a buffer •  Setbacks should enhance pedestrian experience •  Off-‐street parking should not disrupt pedestrian experience •  Shared off-‐street parking reduces non-‐produc/ve land use
