With nothing being scheduled for it to decide, the Twentynine Palms Planning Commission will confine itself to studies at its meeting tonight. The agenda of the Twentynine Palms Planning Commission for November 19 consists of two study session discussions. The first is a discussion by the Commission of city projects. The other is yet another discussion of the Development Code Update (number 29 in the series). The meeting starts at 6 p.m. in City Hall on Adobe Road.
