In keeping with the purposes of this chapter, the city encourages planting within overhead utility corridors. However, landscape planting near overhead utility lines and abutting utility support structures has the potential of creating a public safety hazard by causing physical damage, disrupting service, and obstructing access. Therefore, within twenty feet of any overhead utility lines, planting restrictions are as follows:
(1) Tree species at full growth shall not encroach within a ten-foot radial line clearance of all overhead electric utility distribution or transmission lines. Unless ground clearance is greater than thirty feet, mature tree height shall not exceed twenty feet.
(2) A minimum ten-foot clearance shall be maintained around all poles and ground structures to ensure necessary firebreaks and unobstructed access.
