IIRC when Comtel was installed locally the cables from the green box seemed to go under all the pavements with a small "cat" cover outside each property. It sounds to me as if the cable installers got lazy and put pipes under the grass verges instead of the path. There should be some record of what they were planning to do with your local "highways" authority which may not be the same as the authority you bought the land from.
