Description: 4/15/2019Using new photography and the retaining wall feature class, as well as others, I have snapped surrounding features together as they should be. This procedure has taken sometime and I am sure I have missed some things but the vector basemap looks much cleaner now. I would have thought Rochester would have done this for us as a final draft of their services. All of the line features that should be a closed item are now. As I run across others they will be corrected as well. 7/17/2018 This, feature class was updated with a 2017 survey. The Old High School property was surveyed by Timothy W. Caldwell License number L-5232, September 27, 2017, Mattern & Crag Engineers and Surveyors. Data is considered 90% accurate, and data was collected between 8/ 5-18 / 2017. All coordinates are based on NCGS NAD/83/ 2011 and all elevations are based on NAVD 88. 4/12/2018 These features were updated using the knowledge of the Appalachian State Physical Plant staff. 8/11/2017 In house images were attached to all of the lines, also additional missing lines were drawn using 2014 aerial photography, and a python script was run to place all images into an organized folder.3/4/2017 Editor Tracker has been added to this feature class. All of the attributes have been appropriately updated and meaningless columns omitted. However, this is a work in progress.A headwall usually constructed of concrete, is a retaining wall built at the outlet of a drainpipe or culvert, where the end of the pipe is flush with the outer surface of the wall. In this dataset 18 lines were remotely sensed using aerial photography. The total length of the lines is 2351feet. There is no information about, the type of wall, condition, or when this data was located.Woodard & Curran, Rochester & Associates, Inc.
