- (1) Project activities must adhere to the general conditions in OAR 141-089-0650 and the following project-specific conditions.
(2) Anchoring. Anchoring materials must:
- (a) Not restrict or redirect flows; and
- (b) Be set below grade to minimize the appearance.
(3) Ballast. Use of rock and gravel for ballast is limited as follows:
- (a) Only the minimal amount necessary may be used to achieve project objectives and cannot function to armor the bank;
- (b) Rip-rap and rock toe placement is not allowed;
- (c) Rock must be placed in a way as to minimize adverse impacts to the active channel and downstream banks; and
- (d) All rock must be placed, not dumped, from above the bank line, from a dewatered position or, from a construction platform-mounted position.
(4) Native Materials. Material used must be similar to materials currently or historically found naturally in the stream reach except as follows:
- (a) Use of straw bales, straw or coir logs, jute fabric, or other biodegradable material may be used where necessary for temporary erosion control;
- (b) Other temporary use of nonnative materials as necessary for compliance with OAR 141-089-0650 (General Conditions);
- (c) Pinning material for large wood placements; and
- (d) Erosion-resistant ballast rock may be sourced from an upland location but cannot include broken concrete, asphalt, or other waste materials.
- (5) Uplands. A project may not create new uplands nor reestablish lost uplands resulting from the bank erosion event(s), other than incidental creation necessary to achieve the bio-engineered bank stabilization.
