The cables under my area of responsibility are transcontinental and take a variety of different routes, ranging from railroad property, urban neighborhood streets, farmland and suburban developments. In many places the cables now run through residential front and back yards.
By law, anytime the ground is broken (other than agriculture) a dig report is required to be filed. If any of these reported dig sites are within a one-quarter mile buffer for our cables I get the report to make the final decision as to whether or not the activity poses a threat to our service. Depending on the time of year, I typically receive 20 to 90 reports per day. Each of these reports contains a "method of excavation" entry. Other than "invisible fence" installations, I've never received a report where a "cable plow" was used.
