7. Wetlands Will be Coraoensated at a Minimum of 2:1 



- 



For wetland compensation projects involving a Hydraulic 

 Project Approval (HFA), a minimum of 2:1 compensation to 

 impacted area shall be required. If 2:1 compensation is 

 infeasible, written justification for the lesser compen- 

 sation must accompany the draft HPA when it is returned to 

 Olympia for processing. 



For wetland compensation projects not involving an HPA, 

 a minimum of 2:1 compensation shall be recommended to the 

 permitting agency. 



8. Off-Site Wetland Compensation Should Restore or Enhance 

 Existing Hydraulics 



In compensation projects, flood storage capacity and 

 year-round surface water quantity should be restored 

 and/or enhanced to preserve aquatic resource habitat. 

 This is usually accomplished by keeping the compensa- 

 tion site in the same drainage basin as the original 

 wetland when onsite compensation is not possible. 



9. Native Plants are Preferred in Wetland Sites 



The following native plants will be preferred in 

 any wetland revegetation projects:

integrif olia, Pterygophora californica )
