BUFFER INFORMATION All utility members are responsible for providing their mapping data to Texas811. We accept several mapping formats, with the preferred formats being KMZ and shapefiles. If you do not have data in this format, please contact the GIS Team for assistance prior to submission. We have several options to support mapping development, including recommended contractors. Texas811 has the ability to place an additional buffer around mapping data provided. This buffer works to limit damage to your utility lines. The minimum utility line buffer is 10 feet. We recommend that you provide us with larger buffers wherever you may be unsure of the exact location of your buried lines. There are no limitations on the maximum utility line buffer that you may apply to your mapping file, and your mapping coverage area may be updated within in our database as often as you request and throughout the tenure of your membership. When selecting your buffer size, please keep in mind that Texas811 places a 150-foot buffer around the map selection, which is selected based off of directions and/or addresses provided by the excavator. To ensure that all assets remain protected, the buffer placed around the map selection acts as a cushion to the directions provided, which is typically an approximation. This buffer coupled with your buffer, (if applicable), allows the Texas811 system to identify registered utility lines where locates may be required. Reminder: The one-call system operates as a machine comprised of several different stakeholders. Texas811 acts as a liaison between the protection of your underground utility lines and the people who are living and working around them. When driving directions and work site information is provided, safety and damage prevention are our main goals. Your organization will be notified when your underground mapping data (buffer included, if applicable) intersects with the buffered marking placed on the Texas811 map; either by an agent in our contact center or by an excavator who processes their own tickets online. You can easily view your current mapping through SAE (Service area Editor) , an online program included in your membership. To request access to SAE , please contact GISMail@Texas811.org .
