Appendix IV 



—If the trail is part of the National Historic Trails 

 System, how does the management plan 

 evaluate the physical integrity of the 

 segment? 



MITIGATING EFFECTS 



The following measures, where applicable, are 

 offered as suggestions to managers and cultural 

 resource contractors in dealing with mitigation of 

 trail remains: 



—Avoid impacts to all physical remains with good 

 integrity. 



—Avoid impacts to locales with good environ- 

 mental integrity. 



—Cross the setting where the integrity of setting 

 has already been compromised. 



—Avoid running a linear project parallel to a trail. 



—Cross at 90° using a dog-leg or S-curve. 



—Relocate the proposed disturbance where it will 

 be less visible from the trail (i.e., behind a 

 rise). 



—Restrict the width of a working right-of-way 

 within a visual buffer on either side of a trail. 



—Avoid any blading on a right-of-way within the 

 buffer zone if a track can do the job. 



—Consider special rehabilitation measures (such 

 as revegetation) which will help re-establish 

 the integrity of the trail. 



— Consider special interpretive measures (such as 

 signing) which will help mitigate the impact 

 of the project. 



— Consider special preventive measures (such as 

 fencing) to reduce the area affected by the 

 project.
