      s 130. Patrol Roads and Access Ramps.

      (a) The following definitions apply to this section:

      (1) Access Ramps - "Access Ramps" mean those ramps that provide access to 
      the levee crown from adjacent property and roads.

      (2) Patrol Roads - "Patrol Roads" means those roads that provide vehicular 
      access along levee crowns and flood channels for inspection, maintenance, 
      and flood fighting.

      (b) Patrol roads must meet the following criteria:

      (1) Patrol roads must be surfaced with a minimum of four (4) inches of 
      compacted, class 2 aggregate base (Caltrans Spec. 26-1.02A, July 1992) 
      which is incorporated by reference, or equivalent.

      (2) Patrol road surfacing material must be compacted to a relative 
      compaction of not less than ninety (90) percent per ASTM D1557-91, dated 
      1991, which is incorporated by reference with moisture content sufficient 
      to obtain the required compaction.

      (3) Compaction tests by a certified soils laboratory may be required to 
      verify compaction.

      (4) Paved patrol roads must meet the design requirements for paved bicycle 
      trails, section 132.

      (5) Levee crown surfacing must meet the following additional requirements:

      (A) Where the crown width is less than sixteen (16) feet, the minimum 
      surfacing width must be ten (10) feet with a smoothly tapered transition 
      to the edge of the levee shoulder.

      (B) Where the crown width is sixteen (16) feet or more, the minimum 
      surfacing width must be twelve (12) feet with a two (2) foot-wide taper at 
      each edge of the surfacing.

      (C) The crown roadway must be sloped a minimum of two- (2) percent.

      (6) Any patrol road which has been excavated or damaged must be restored 
      to its original condition.

      (c) Access ramps are of two common types, head-on or side approach, and 
      must meet the following criteria:

      (1) Access ramps must be constructed of approved imported material.

      (2) The surfacing for all access ramps must be the same as for patrol 
      roads. Subdivisions (b)(1), (b)(2) and (b)(3) of this section also apply 
      to access ramps.

      (3) Any excavation made in a levee section to key the ramp to the levee 
      must be backfilled in four- (4) to six- (6) inch layers with approved 
      material and compacted to a relative compaction of not less than ninety 
      (90) percent per ASTM D1557-91, dated 1991, and above optimum moisture 
      content.

      (4) Compaction tests by a certified soils laboratory may be required to 
      verify compaction.

      (5) All access ramps must be constructed in such a manner so as to direct 
      all surface drainage away from the levee section.

      (6) Approved gates must be installed across access ramps at locations 
      where vehicular access by the public is possible.

      (7) Side approach ramps must be used on the waterside levee slope.

      (8) Side approach ramps on the waterward slope of the levee must slope 
      downstream.

      (9) Typical plans for each type of approach ramp with restrictions and 
      requirements are shown on Figures 8.08 and 8.09.
