4.1 Location Standards

   Sidewalks must meet the following locational requirements:

   A.   At least one sidewalk is required to a project from each street on which the project has frontage, unless there is no vehicular access from a street because of a physical barrier, such as a drainageway or an unbroken security barrier (e.g., a wall or fence). The sidewalk should be located to minimize any conflict with vehicular access to the project;

   B.   A sidewalk is required adjacent and parallel to any access lane or PAAL on the side where buildings are located (See Figure 1);

   C.   A sidewalk is required adjacent to any parking space accessed by a PAAL where the space is located on the same side of the PAAL as any building and no other parking spaces or PAALs intervene (See Figure 2);

   D.   Sidewalks must connect all areas of the development and must also connect to the pedestrian circulation path located along any adjacent street;

   E.   Sidewalks shall be flood free for all storm discharges of up to and including a ten-year frequency flood event. Drainage flowing across all pedestrian circulation paths shall be conveyed under the path for up and including the ten-year frequency flood events, except at street intersections, pedestrian crossings, and PAAL pedestrian crossings;

   F.   Sidewalks or pedestrian refuge areas cannot be located between any motor vehicle parking space and the PAAL providing access to that space;

   G.   Sidewalks or crosswalks cannot cross any type of stacking areas for drive-through lanes; and,

   H.   In Land Use Classes where the public does not have access to certain portions of the site , a four- foot wide pedestrian refuge area must be maintained between any enclosed structure and a PAAL (See Figure 6).

4.2 Physical Separation from Travel Lane Standards

   A.   Sidewalks associated with PAALs must be physically separated from any vehicular travel lane by means of curbing, grade separation (minimum six inches), barriers, railings, or other means, except at designated crosswalks;

   B.   When bollards or architectural features are used to provide physical separation, the maximum separation between the barriers is five feet clear (See Figure 5); and,

   C.   Barriers must be permanently affixed to the sidewalk by pinning, set in foundations, etc. or when the use of architectural features is proposed such as planters, the containers must be of sufficient weight and size to prevent the removal of such features.

4.3 Sidewalk Specifications

   A.   Width

   All sidewalks must be a minimum of four feet wide and installed to avoid any obstruction which decreases the minimum width to less than four feet (See Figure 3);

   B.   Vertical Clearance

   All sidewalks must have a minimum unobstructed vertical clearance of 84 inches (See Figure 4);

   C.   Composition

   Sidewalks must be constructed of:

      1.   Portland cement concrete, four inches thick, with a smooth or broom-finish;

      2.   Brick Pavers set in a bed of cement;

      3.   Resin Pavement Mixture that complies or is equivalent to ASTM D 4123;

      4.   Any surfaces equivalent in smoothness, hardness, and durability;

      5.   Asphalt or asphaltic concrete may be used only for jogging paths, nature trails which are part of an accessible route, and pedestrian refuge areas which are not required to be connected to the pedestrian circulation path, as listed in Section 7-01.3.3.B; or,

      6.   Compacted decomposed granite or similar material cannot be used for construction of a required sidewalk system that is part of the required accessible route or pedestrian circulation path.

   D.   Slope

   Slopes shall comply with the accessibility requirements in accordance with the city’s adopted Building Code.

   E.   Drainage

   At any point where a ten-year frequency flood discharge is proposed to cross a sidewalk or pedestrian access, the sidewalk/access shall be designed and constructed to convey up to and including the ten-year frequency flood flows under the sidewalk/access.
