§ 91.02 REQUIRED PLATTING.

   Sidewalks shall be required for any new construction in any new subdivision platted after the date of this subchapter.

(Ord. 103-01, passed 5-15-01)

§ 91.03 MINIMUM ACCEPTABLE STANDARDS.

   The minimum acceptable standards for sidewalks constructed as required by this subchapter shall be as follows:

   (B)   Length: it shall be placed along the entire length of developed street frontage on both open ditch and curb and gutter sections.

   (C)   Reinforcing:

      (1)   Material: open hearth new billet steel.

      (2)   Yield strength: 60,000 pounds per square inch minimum.

      (3)   Splices: 24 bar diameters.

      (4)   Bar size and spacing: No. 3 bars at 18-inch centers, each way.

      (5)   Bar support: metal or plastic “chairs” shall be used to hold bars in position during placement of concrete.

   (D)   Concrete mixture:

      (1)   Flexural strength: 650 pounds per square inch minimum modulus of rupture at 28 days (American Society of Testing and Materials, C-78, 3d point loading).

      (2)   Slump: four inches maximum.

      (3)   Cement factor: five bags per cubic yard, minimum.

   (E)   Cement: Type I (normal) Portland cement, or with engineer’s approval, Type III (high early strength).

   (F)   Aggregate: course and fine aggregate shall meet the requirements of State Highway Department Standard Specification Item 360 for concrete pavement.

   (G)   Jointing:

      (1)   Depth of contraction joints: one-fourth of slab thickness.

      (2)   Transverse spacing: 20 feet.

      (3)   Expansion joints: at intersections.

      (4)   Wood joints: Sound Heart Redwood.

      (5)   Joint seal: ASTM 0920, Type S, Grade P or NS.

   (H)   Curing: curing method shall retain at least 97% of moisture at 24 hours, at least 95% at three days and at least 91% at seven days. American Society of Testing and Materials Procedure C-5.

   (I)   Tests: flexural strength, three molds per 200 linear feet

   (J)   Placement: concrete shall not be placed on frozen subgrade; when air temperature is 38°F or below; when air temperature is below 42°F declining; when finishing cannot be completed during natural daylight.

   (K)   ADA requirements: at the junction of the sidewalk with each driveway and street, the sidewalk must be transitioned to meet any requirements of the Americans With Disabilities Act (ADA).

(Ord. 103-01, passed 5-15-01)
