Twentynine Palms’ Project Phoenix will have a multipurpose facility including a gymnasium, meeting rooms and banquet rooms with kitchens as well as a public library. That’s the direction City Council gave its staff last night for the city’s ambitious plan to expand and modernize its downtown corridor. In other business, the Council agreed to apply for a $448,000 grant to study the long-term impacts from the historical use of septic tanks on groundwater reliability, storage and quality. The move is the first step in a long-term effort to discuss and ultimately solve the problem of treating wastewater in the city. Finally, the Council appropriated $131,000 to complete several curb, gutter and sidewalk improvement projects citywide.
