If the restriction of vehicular or pedestrian traffic authorized pursuant to Section 12.40.020 of this chapter requires construction by a private entity of improvements such as fencing, gates, or lighting in the public right-of-way, a revocable encroachment permit and an excavation permit must be obtained from the public works department. The revocable encroachment permit must be issued simultaneously with the authorization of such restriction by the city council. The excavation permit, if required, may be issued subsequent to city council authorization of such restriction, but must be obtained prior to the construction of any improvements in the public right-of-way. The city manager, in his or her discretion, may waive the fees required for these permits. (Prior code § 38.17.253)
