Sidewalks shall meet the minimum widths outlined below. The location of sidewalks within the public right-of-way shall be as approved by the City during the design process.
Street Classification | Min. Sidewalk Width from back of curb | Location unless otherwise approved2 |
|---|---|---|
ODOTR.O.W. | 6 ft or ODOT standard | Curbline |
Arterial or Collector Street | 5 ft | Property Line w/landscape strip1 |
Downtown Area streets | Per Silverton Downtown Master Plan | Per Silverton Downtown Master Plan |

Local Street | 5 ft | Property Line w/landscapestrip1 |

2Sidewalk locations, widths and landscape strip widths are shown on figures in SDC 3.4.100.E, which may be modified based on conditions noted under SDC 3.4.100.F.
e. Water meters, utility poles, etc. are not permitted within sidewalks unless authorized in writing by the City Engineer.
f. Where single or clustered mailboxes or other objects are within a sidewalk, the sidewalk shall be widened to provide clearance equal to the required sidewalk width. For retrofit installations where specifically approved by the City Engineer, the sidewalk clear space may be reduced to 48 inches minimum, provided that all other PROWAG requirements are satisfied. All existing mailboxes shall be set on new posts at the time of sidewalk construction.
g. Sidewalks to be constructed in conjunction with a development provided as part of a development may be deferred at the City's option until building construction except for the following situations:
1) Arterial or collector streets (SDC 3.4.500.A).
2) Sidewalks along streets from which vehicular access to the fronting lot is restricted.
3) Sidewalks fronting existing structures.
4) Offsite sidewalks not abutting the property within the development.
5) All required ADA handicap access ramps within or adjacent to public or private streets, as well as sidewalks required for ADA access to CBU mailboxes, including installation of an ADA pedestrian access curb located within 50 feet of the CBU (Oregon Structural Specialty Code 1111.4.1).

j. Sidewalk Grades & Vertical Alignment.
1) Except for pedestrian street crossings (see Section 2.16, Intersections & Pedestrian Crossings), the sidewalk grade for pedestrian access routes contained within the public right-of-way shall not exceed the general grade of the adjacent street.
