LDC § 7.01.030. Thoroughfare Types Overview.

The thoroughfares of a city are one of the most important elements in defining community character. This role must be considered along with the movement of cars, bicycles, and transit. Due to this important role in placemaking, in addition to their contribution of a major percentage of public space in every city, thoroughfares' standards must be considered alongside building form, building types, frontage types, civic spaces and landscaping in creating urban environments.

There are two kinds of thoroughfare types within this chapter: those that represent transformations of existing streets within existing right-of-ways, and those that can be used to integrate new streets into larger parcels that require a new street and block network. Transformations to existing streets shall match the designations set forth in the General Plan.

All of the elements of the thoroughfare are context-based. Elements of the thoroughfares include pedestrian and bicycle oriented principles. The elements included in these standards start with the classification of movement type and design speed for each thoroughfare. Next, applicable Transect zones are listed, followed by overall width and pavement width, the number of lanes, and the lanes' specific maximum sizes. Last are the edges, which include drainage collection type, planter type, lighting type (street lighting per City standard), and walkway type and curb radii at intersections. Bulb-outs are encouraged to facilitate a pedestrian friendly environment.

These thoroughfares are assigned to one or more Transect zones.
