Current through Register 2024 Notice Reg. No. 28, July 12, 2024
Watercourse crossing drainage structures on Logging Roads
						shall be planned, constructed, reconstructed, and maintained or removed
						according to the standards provided in this rule section.
(a) The planning for and use of Logging Road
					 Watercourse crossings shall include the evaluation and documentation of
					 significant existing and potential erosion sites consistent with
					 14 CCR
					 §
												963.1(e).
(b) The number of crossings shall be kept to
					 a Feasible minimum. Existing Logging Road Watercourse crossing locations shall
					 be utilized where Feasible and appropriate.
(c) All new drainage structures and
					 facilities on Watercourses that support fish or listed aquatic Species shall
					 allow for unrestricted passage of all life stages that may be present, and
					 allow for the natural movement of bedload to form a continuous bed through the
					 crossing. Such structures and facilities shall be fully described in the Plan
					 in sufficient clarity and detail to allow evaluation by the review team and the
					 public, provide direction to the LTO for implementation, and provide
					 enforceable standards for the inspector.
(d) In Watersheds with Listed Anadromous
					 Salmonids, a description of all existing permanent Class I Watercourse
					 crossings shall be provided, where fish are always or seasonally present or
					 where fish passage is restorable. Where it is determined that current crossing
					 conditions may be adversely affecting fish passage at any life stage, the RPF
					 shall disclose such conditions in the Plan and propose measures, if Feasible,
					 to address these conditions subject to the Director's review and
					 determination.
(e) The location of
					 all new permanent constructed and reconstructed, and temporary Logging Road
					 Watercourse crossings, including those crossings to be abandoned or
					 deactivated, shall be shown on a map. If the structure is a culvert intended
					 for permanent use, the minimum Diameter of the culvert and the method(s) used
					 to determine the culvert Diameter shall be specified in the Plan.
(1) The location of all Logging Road
					 Watercourse crossings to be constructed or Reconstructed shall be flagged or
					 otherwise identified on the ground prior to the pre-harvest inspection, if
					 necessary, or prior to Logging Road Watercourse crossing construction or
					 reconstruction. Exceptions may be explained and justified in the Plan and
					 agreed to by the Director if flagging is unnecessary as a substantial aid to
					 examining possible significant adverse effects of the crossing location on the
					 factors listed under
					 14 CCR
					 §
													963(b).
(2) Consistent with
					 14 CCR
					 §
													923.5(a)-(i),
					 drainage facilities and ditch drains shall be installed adjacent to logging
					 road watercourse crossings, as needed, to hydrologically disconnect to the
					 extent feasible the logging road approach from the crossing, to minimize soil
					 erosion and sediment transport, and to prevent significant sediment discharge
					 during and upon completion of timber operations. Guidance on hydrologic
					 disconnection may be found in "Board of Forestry Technical Rule Addendum Number
					 5: Guidance on Hydrologic Disconnection, Road Drainage, Minimization of
					 Diversion Potential, and High Risk Crossings" (1st Edition, revised 04/21/15),
					 hereby incorporated by reference.
