<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This shapefile represents 1 ft. contours based on Lidar-derived terrain elevation data of the City of Boulder 2020 Data Reporcess dataset. Bridge and waters edge breaklines provided by the City of Boulder were used to enforced contour elevations. The horizontal datum for this dataset is NAD83 2011, the vertical datum is NAVD88 Geoid 18, and the data is projected in Colorado State Plane North. Units are in US Survey Feet. NV5 Geospatial collected the City of Boulder 2020 Data Reporcess dataset for City of Boulder between 05/29/20 - 08/03/20. In areas of steep slopes the contour interval precludes the generation of topologically correct contours and some overlap may be seen due to the rapid elevation change in XY space. </SPAN></P></DIV></DIV></DIV> |

In the event the total return count exceeds this limitation, the true last return which generally exists as ground in the dataset is preserved as the 15/15th return, with all other returns consolidated to 14/15th returns.</SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
