 The slope locations were identified by Constitution utilizing 2 foot contours that were created utilizing photogrametry 

survey data. The photogrametry survey was completed between July 2012 and April 2013. The locations indicate 

areas along the project where the centerline crosses slopes (runs perpendicular to the slope contours) between 15% 

and 30%.

 The slope locations were identified by Constitution utilizing 2 foot contours that were created utilizing photogrametry 

survey data. The photogrametry survey was completed between July 2012 and April 2013. The locations indicate 

areas along the project where the centerline crosses slopes (runs perpendicular to the slope contours) greater than 

30%.
