The Contingency Plan may range in complexityfrom a list of plants substituted, to cross-sections of proposedengineered structures. Once approved, it may be installed, and willreplace the approved mitigation/restoration plan. If the failure issubstantial, the City of Renton may extend the monitoring periodfor that mitigation.14.0 BondPrior to beginning any work, the Permittee must provide amitigation/restoration bond or assignment of funds per City ofRenton procedures.
