2. A borehole or pit is not allowed within the median area of a highway except as authorized by the district engineer. Extreme care must be used to prevent the impairment of the ground under the pavement and shoulders of the pavement.

3. Hydraulic or wet boring is prohibited, except that a small amount of water may be used to cool the boring bit if water pressure is not used to drill the bore or displace and wash out the material to be removed.
