{ "layers": [ { "currentVersion": 11.1, "cimVersion": "3.1.0", "id": 0, "name": "County Boundaries", "type": "Feature Layer", "description": "Johnson City Limits: Polygon layer of municipal city limits boundary of Johnson City, TN. Original layer developed from hard copy tax map parcel information and were supplemented by official annexation folder data of every subdivision passed by City Commission of Johnson City since 1885. These folders are kept in Planning Dept and are planned to be scanned and stored in DocStar. As annexations were passed, all corresponding city limits and additional miscellaneous zone layers based on city limits were updated. Annexation used to have a 30 day waiting period and Development Services GIS would try to update every corresponding layer and information the day before the official date. Now when the annexation passes on a Thursday night Commission night, it is official that night. Data SHOULD be updated the next day on FRIDAY following the commission meeting. Bluff City Limits: Updated from Sullivan County Dec 2014 data on 10/18/2016. Carter County Boundary: Polygon feature layer originally created from the parcel outlining tax map 400 and 100 series digitized at GIS Division in the 1980s. Used in some area maps. Does not change nor need updating. Elizabethton City Limits: Origin was a hand delivered shape file from either Carter Co. 911 or Elizabethton City courtesy of Glenn Berry. Used as a reference in regional maps, maps of Johnson City, and especially Tweetsie Trail maps. Was last updated August 2016 from Elizabethton Web Page. Jonesborough City Limits: Original layer developed from hard copy tax map parcel information. Updates are received from Washington County E911 when Jonesborough lets them know about an annexations. Used in the Johnson City street map, Washington County Road map and numerous other maps showing regional city limits. Kingsport City Limits: Updated semi-annually by requesting a copy from Kingsport, TN contact Jake White, GIS Manager. Last update 7/29/2016. Used in several of our regional maps and ArcReader maps. Sullivan County Boundary: ? Unicoi City Limits: ? Unicoi County Boundary: Polygon feature layer originally created from the outlying parcel tax map 400 and 100 series digitized at GIS Division in the early days. Used in some area maps. Does not change nor need updating. Washington County Boundary: Thematic polygon layer developed by digitizing off Washington County Assessor's tax maps identifying Washington County parcels. Layer has not been changed nor should it be changed without official State or Assessor's office notification. Watauga City Limits: Updated from Carter Co admin layer Sept 2016. Used in several of our regional maps and ArcReader maps.
