Southern California may be shrouded by thick fog this week, but progress on an affordable housing complex is clear in South Los Angeles. Paloma Terrace, a development from the Retirement Housing Foundation, has now reached its fourth and final level above ground. The approximately $15-million project will include 59 one-, two- and three-bedroom apartments. According to a document from the California State Treasurer’s Office, rents in the low-rise complex will range from $458 to $1,272 per month. Units will be reserved for households making between 30% and 60% of the Los Angeles area median income. The building, designed by Killefer Flammang Architects (KFA), includes activity rooms, a private library, a basketball court and a central courtyard. KFA designed Paloma Terrance for LEED (Leadership in Energy and Environmental Design) certification for its environmentally-friendly features and energy-efficiences, under the LEED for Homes program (a product of the U.S. Green Building Council). The project is replacing an approximately .95-acre lot at 5000-5024 S. Main Street. A completion date is currently unclear. Immediately north of the development site, another vacant lot has given way for an expansion of what will eventually become a charter middle school.
