The director may, from time to time, designate a number of residential permit parking zones within the Deep Ellum District as the director determines necessary to provide for the parking needs of the residents of that district. The director shall conspicuously post signs within each zone indicating the times and conditions for which parking is by permit only. A residential permit parking zone becomes effective five working days after signs are in place in the zone, during which time, courtesy notices will be given to all motor vehicles parking in the zone.
