a. In addition to the definitions contained in Division 1 of these Standards, the following definitions may apply particularly to street systems. Unless otherwise defined in these Design Standards, the following definitions and abbreviations shall apply whenever used. Other definitions as outlined in the Oregon Standard Specifications for Construction- OSSC (ODOT/APWA) shall also apply.

1) Abbreviations: Acceptable abbreviations for pavement materials are as follows:

a) AC-Asphalt Cement

b) PCC - Portland Cement Concrete

2) Alley: A public right-of-way not more than 20 feet and not less than 10 feet in width, which intersects with a public street.

3) Arterial Street: A street of considerable continuity which is used for moving large volumes of traffic to and from the highway and for interconnection between major areas of the City.

4) Bike Lanes: A designated travel-way for bicyclists which is established within the roadway directly adjacent to the outside vehicular lane or on the shoulder.

5) Bike Path: A designated travel way for bicyclist which is completely separated from the vehicular travel lanes and is within independent right-of-ways.

6) Bike Route: A designated travel-way for bicyclists which can be shared with vehicular traffic. The roadway is designated with signs for bicycling (no pavement markings for the bike route or delineation of parking spaces is used).

7) Clear Vision Area: A triangular area on a lot at the intersection of two streets or a street and a railroad, the sides of which are lines measured from the comer intersection of the right-of-way lines. The third side of the triangle is a line across the comer of the lot joining the ends of the other two sides. Where the lines at the intersections have rounded comers, the right-of-way lines will be extended in a straight line to the point of intersection.

8) Collector Street: A centrally located street for moving traffic from arterials to local streets.

9) Cross Slope (Pedestrian Path): The grade that is perpendicular to the direction of pedestrian travel.

10) Cross Slope (Vehicle Path): The grade that is perpendicular to the direction of vehicular travel.

11) Crosswalk: See Pedestrian Street Crossing.

12) Curb Ramp: A ramp that cuts through or is built up to the curb. Curb ramps can be perpendicular, parallel, or a combination of parallel and perpendicular.

13) Detectable Warning: Detectable warnings consist of small, truncated domes built in or applied to a walking surface that are detectable by cane or underfoot. On pedestrian access routes, detectable warning surfaces indicate the boundary between a pedestrian route and a vehicular route for pedestrians who are blind or have low vision. Detectable warnings shall contrast visually with the surrounding sidewalk surface.

14) Downstream Intersection: The nearest intersection from a driveway located in the direction of traffic flow of the nearest lane of the abutting street.

15) Expansion Joint: A joint to control cracking in the pavement structure and filled with preformed expansion joint filler.

16) Grade: The degree of inclination of a road, sidewalk or slope, in the direction of travel.

17) Intersection: The meeting point of two streets having at least three legs.

18) Local or Residential Street: A facility not designed as an arterial or collector. It serves primarily to provide direct access to abutting land and offers the lowest level of traffic mobility. Through traffic movement is deliberately discouraged.

19) Longitudinal Joint: A joint which follows a course approximately parallel to the centerline of the roadway.

20) Natural Grade: The grade with the land in an undisturbed state.

21) One-Way Driveway: A driveway of either ingress or egress, but not both.

22) Parking Space: A designated space in a parking area for the parking of one motor vehicle. An off-street parking space is a designated space for the parking of one motor vehicle, which is located on private property rather than on a public street.

23) Pedestrian Access Route: A continuous and unobstructed path of travel provided for pedestrians with disabilities within or coinciding with a pedestrian circulation path.

24) Pedestrian Circulation Path: A prepared exterior or interior surface provided for pedestrian travel in a public right-of-way.

25) Pedestrian Street Crossing: A marked or unmarked route, providing and accessible path to travel from one side of the street to the other. Pedestrian street crossings are a component of the pedestrian access route and/or the pedestrian circulation path.

26) PROWAG: Public Right-of-Way Accessibility Guidelines; see definition in Division 1.

27) Running Slope: The grade that is parallel with the direction of pedestrian travel.

28) Sidewalk: A right-of-way deeded, dedicated, and designated for the use of non­ motorized vehicles and pedestrians.

29) Streets or Roads: Any public highway, road, street, avenue, alley, easement or right-of-way used or to be used for vehicle movement. Full street improvements include curb and sidewalk on both sides, storm drainage and fully improved in accordance with these standards.

30) Structures: Structures designated on the standard plans as catch basins, manholes, etc. Detailed drawings of structures or devices used in City work and mentioned in these standards are included in the standard construction specifications.

31) Superelevation: The vertical distance between the heights of the inner and outer edges of pavement on horizontal curves.

32) Three-Quarter (3/4) Street: A ±75 percent portion of the ultimate width of a street, but not less than 25½ feet from face of curb to edge of pavement, usually along the edge of a development, where the remaining portion of the street shall be provided when adjacent property is developed. 3/4 street improvements include curb, piped storm drainage and sidewalk on one side, and drainage facilities on the non-curbed side of the street.

33) Transition: The taper between portions of a street with different pavement widths.

34) Transverse Joint: A joint which follows a course approximately perpendicular to the centerline of the roadway.

35) Travelled Way: That portion of the roadway for the movement of vehicles, exclusive of shoulder and auxiliary lanes.

36) Turnaround Area: A paved area of sufficient size and configuration that emergency vehicles may maneuver around to head in the opposite direction without having to move in reverse more than once.

37) Turning Space: An area at the top of bottom or a curb ramp, providing a space for pedestrians to stop, rest, or change directions (also referred to as a landing).

38) Turnpike Street: Any public street, road or right-of-way which has been paved for vehicular movement and does not have curbs, sidewalks or piped storm drainage facilities.

39) Two Way Driveway: A driveway functioning as both an exit and entrance.

40) Upstream Intersection: The nearest intersection from a driveway located in the direction opposite the traffic flow of the nearest lane of the abutting street.
