11/16/2021 Updated Sanford drainage with georeferenced PDF as built, still waiting for a .dwg. I figured this was better than nothing.

App State Lake Notes4/16/2021

Today Daniel Gryder and I located the storm drains to add to the work performed by Rochester for the App State lake around 2016. We had to make a number of assumptions since most of the junction boxes, and drop inlets were inaccessible, for a number of reasons. I feel more field work needs to be done for further conformation, maybe a camera. This would show, where the water actually flows, the condition of the pipes and junction boxes, and if any repair is needed. If there are any questions contact me, Edward Hyle, hyleea@appstate.edu. Note: many of the storm water junction box lids have sewer lids on them.

2/25/2020 This storm water data around the Leon Lavine Hall of Health Sciences, has been updated using a georeferenced PDFs, such as C400, C403, C500, a land survey 02/04/2020 by Allen geomatics job 1234 last revised 07-17-2020 336-998-0215 L-3810. Jeffery C. Allen. Also, CAD drawings were used; however, could not be properly converted into GIS since X refs were missing. Field verification from the mechanical shop is a must to ensure accuracy of contracted performed work.

2/19/2019: Monday 2/18/2019 Eric Greer and Daniel Gryder did some field work and camera work between Varsity and Rankin Science. They found degraded pipes, and pipes full of water and debris. It appears some of the pipes have settled in the middle so there is a belly in them, reducing the slope, and reducing their effectiveness to move storm water.

The Stormwater lines and points on the east side of campus have been updated using four different surveys listed below. During this process, it was observed that the surveys did not agree on pipe size and in some cases location of infrastructure. The best educated guesses were used, the latest surveys, to add the lines and points to the GIS Portal. It appears that the best way to know what stormwater infrastructure is there and its condition is to camera the lines. Also working with stormwater and surveys it is apparent that many of the systems need maintenance. It is not uncommon to see on surveys the message “full of debris.” During flood events objects can enter structures forming damns and restrictions.

7/16/2018 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.

4/16/2018 These features have been updated using a DWG. provided by Davis, Martin and Powell survey, made available 1/3/2018. 6415 OLD PLANK RD, HIGH POINT, NC 27265

(336) 886-4821 | WWW.DMP-INC.COM | LICENSE: F-0245. The DWG was layered out by NRLP mapping department.

4/12/2018 These features were updated using the knowledge of the Appalachian State Physical Plant staff.

8/14/2017 Rochester’s PDF's were attached to the CCTV surveyed Storm Water polyline lines. Relevant in house images were also attached to other polylines. Storm pipe repair July 2017 in front of APH and the new score board at the football stadium July 2017. It was decided that all videos will be hosted elsewhere on ASU’s network and attached via URL.

7/25/2017 Added the Storm_Pipe_CCTV_Inspection to the Storm_Pipe feature class, removed found duplicate polylines. Added polylines when needed and updated conflicting attribution.

3/6/2017 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 storm pipe is a structure used to move unwanted water away from structures. In this data set there are 1016 sections of pipes located. 974 of these pipe sections, Appalachian State University is listed as the owner while 42 of the pipe sections the owner is left blank. The Accuracy column list 907 field located, 67 approximate, and 42 are left blank. The following columns are either zero or left blank: photograph, up_id, down_id, height, width, length, pipe_slope, install_yr, and source. The column pipe_shape has two entries Round and 3177.61. The comments column also has limited comments, which consist of inverts inaccessible, full of debris, assumed size, material &C. Pipe size is also very variable, here is a list of the attribute table: 1 is 72”x72”, 1 is 72”, 1 is 5’x8’, 1is 6’x8’, 5 are 66”, 4 are 60”, 1 is 54”, 8 are 48”, 5 are 42”, 27 are 36”, 17 are 30”, 88 are 24”, 146 are 18”, 313 are 15”, 208 are 12”, 7 are 10”, 41 are 8”, 31 are 6”, 2 are 4”, 4 are unknown, and 103 are left blank. The pipes are made of various materials and are listed as follows: 18, VCP, 512 RCP, 62, PVC, 176, HDPE, 7, DIP, 15 CPP, 1 concrete, 118 CMP, 103 blank, and 4 unknown. (VCP), vitrified clay pipe is pipe made from a blend of clay and shale that has been subjected to high temperature to achieve vitrification, a process which results in a hard, inert ceramic pipe. (RCP), reinforced concrete pipe is the most durable and longest-lasting pipe available for underground usage it can last more than 100 years. (PVC), Polyvinyl chloride, more correctly but unusually (polyvinyl chloride), is a widely produced synthetic plastic polymer, after polyethylene and polypropylene. HDPE, high density polyethylene pipe is extremely corrosion resistant and has an extremely long service life. (DIP), Ductile iron pipe is a pipe made of ductile iron used to manufacture the pipe is characterized by the spheroidal or nodular nature of the graphite within the iron. CCP stands for corrugated plastic pipe also known as HDPE. CMP, corrugated metal pipe, is fairly inexpensive has a predictable service life, comes in a wide range of gages, corrugations, and shapes in diameters ranging from 12” – 144”. 67,013 feet of storm drains have been located in this attribute table.

/6/2017 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.

44 lengths of pipe were robotically inspected using CCTV (closed-circuit television) technology. The inside diameters ranged from 0”, 15”, 18”, 24”,30”, 36”, 42”, 48”, 66”, 72”, and 84”. In the pipe size column two of the lines are blank with no measurement. These inspections were preformed between 7-13-2015 and 7-16-2015 according to the video footage. The inspected pipes consisted of CMP, 14, CCP,1, HDPE, 3, RCP, 24 and two lines are blank. CMP, corrugated metal pipe, is fairly inexpensive has a predictable service life, comes in a wide range of gages, corrugations, and shapes in diameters ranging from 12” – 144”. CCP stands for corrugated plastic pipe also known as HDPE, high density polyethylene pipe. This type of pipe is extremely corrosion resistant and has an extremely long service life. RCP,reinforced concrete pipe is the most durable and longest-lasting pipe available for underground usage it can last more than 100 years. The accuracy is listed as (8), approximate, (33), field located, and (3), are blank. The comments are limited, but include, inverts inaccessible, and 5772 connects to an unknown JB we called 5772A. Video_2 list these comments: 5337 to 54486 (6.3 ft).VOB, APH to 2361.VOB, Peacock_Duncan_Daylight to 59019.VOB. The owner is listed as Appalachian State University for all but, 3 they are blank. The total length of pipe inspected is 6341’.
