f. The wildlife values offered by early successional stages of a wetland 

 bank site will be credited to ITD at the time of a proposed trade according to 

 the amortization process outlined by HEP. 



g. The wetland bank may be used to mitigate for cumulative impacts to 

 wetlands resulting from several roadway activities. 



8. Evaluation Methods: 



a. The FHWA Method for Wetland Functional Assessment (Adamus 

 method) may be used to evaluate wetland functions and values. The US 

 FWS Habitat Evaluation Procedures (HEP) may be used to evaluate wildlife 

 values when they are of prime concern. Both methods may be used in 

 combination to provide the greatest level of detail. Wetland evaluations 

 shall be done by a team, with representatives from interested agencies. 



b. Neither Adamus nor HEP may be required in simple situations where 

 best professional judgement will do. Full documentation will be required, 

 regardless of the method of assessment . 



c. The appropriate assessement method(s) will be agreed to by 

 representatives from each of the Interested agencies. 



9. Record Keeping: 



a. ITD will establish and maintain records which document the activity of 

 the wetland bank accounts. Signatories to this memorandum of agreement 

 and other interested agencies will be sent periodic statements documenting 

 the status of the account. Statements will be generated after each 

 transaction and at the end of each construction season. 



10. Pilot Project: 



a. The initial wetland banking effort will be limited to pilot projects in borrow 

 sources. In addition, ITD may inventory existing wetlands for potential 

 enhancements. The experience gained by the pilot projects will be used to 

 review and modify this agreement prior to further aevelopment of the 

 wetland bank. 



11. l\Aodification and Termination of the l\1emorandum of 

 Agreement: 



a. This agreement and the attached operating procedures may be 

 modified with the approval of all signatories to the memorandum of 

 agreement. Modifications may be proposed by a single or inter-agency 

 team of signatories. Proposed modifications will be submitted for a sixty day 

 period of review to all signatories and approval of the proposed modification 

 will be indicated by written acceptance.
