Pittsburgh's Department of Mobility and Infrastructure launched the 'Street Modification for Outdoor Operations' program to offer three types of street modification requests based on their level of impact to the existing design of the street. Curbside Pick-Up/Delivery is the lowest impact, Sidewalk Extension changes how the parking lane is used, and Full Street Modification is for large block-long parking lane modification or even full street closures.
Curbside Pick-Up/Delivery Zone requests are to convert a few on-street parking spaces to be dedicated as pick-up and delivery zones.
Sidewalk Extension requests are to close a few on-street parking spaces using barriers and signs and use that space to expand available walking or queuing space, set up general public seating, or set up dedicated table service seating for businesses.
Full Street Modification requests are to significantly change the existing street including both partial modifications that still allow vehicles, partial closures such as restricting the street to one-way traffic, as well as full street closures that create large spaces for walking, shopping, and dining.
