c. The wetland bank should be capable of compensating for the wetland 

 functions and values (ie. ground water recharge and discharge, flood 

 storage and desynchronization, shoreline anchoring and dissipation of 

 erosive forces, sediment trapping, nutrient retention and removal, food 

 chain support, habitat for fish and wildlife, active and passive recreation and 

 heritage value) lost as a result of a project . 



d. Strategies to guide development of a wetland bank include: 

 •Developing a wetland of a particular type (eg. palustrine persistent 

 emergent wetland), with no emphasis given to any one function or 

 value. 



•Developing a wetland with emphasis given to functions or values of 

 greatest concern (eg. bald eagle habitat, ground water recharge). 

 Other wetland values may be incidently provided by this strategy 

 but are not an intentional part of the prescription to compensate for 

 losses. 



These and other strategies should be tailored to the anticipated impacts of a 

 proposed roadway project. 



e. Credits may remain in an established wetland bank after its partial use 

 by a project. In such cases, ITD may request regulatory and resource 

 agencies to identify the geographic boundaries that surround other 

 roadway projects for which the wetland bank may be acceptable mitigation. 

 This will allow ITD to anticipate possible use of the wetland bank by future 

 projects. 



f. In accordance with FHWA policy, in-kind wetland replacement outside of 

 roadway right-of-way is acceptable only when in-kind replacement within 

 the right-of-way (ie. within the roadway median, borrow pit areas, 

 interchange areas, and along the roadside) is impossible or extraordinarily 

 expensive. 



g. Guidelines for location of a wetland bank include, but are not limited to: 

 •The bank site should be as close to the impact site as possible. 



•The bank site should be within the same hydrologic basin as the 



impact site. 



•The same public affected by an impact site should be compensated by 



the bank site. 



•The bank site should be within the same ITD district as the impact site. 



h. ITD will insulate wetland bank sites from outside influences and impacts 

 (eg. alteration of drainage or topography by adjacent land owners, 

 disturbances to wildlife by visitors, vandalism). Recognized methods 

 include careful location of the site to minimize impacts, developing large-in-
