A mock-up of the expanded Mariposa at 4824 Baltimore Avenue.

The Baltimore Ave member-owned  food co-op Mariposa needs some help to cover the estimated $2.2 million costs for their new location down the street in the old bank building at 4824 Baltimore. The co-op recently purchased the building.

The co-op has most of the tab covered in a combination of grants, loans and donations. But there are two ways that neighbors can help cover the rest. The first is buying some raffle tickets at a buck apiece. Each ticket gives you a chance to win one of dozens of fabulous prizes, including handmade goods from local artisans, classes and workshops, deals at local eateries and hotel stays. VIX Emporium (5009 Baltimore Ave.) is selling the tickets online here. The raffle drawing will be held Nov. 20 from 2-10 p.m. at Dock Street Brewing Company (701 South 50th), in a shindig that will include live music.

Mariposa is also offering member loans. The loan terms are from five to 10 years and offer a 3 percent return. Many co-ops have used member loans to help with expansion plans and decrease the reliance on banks. The minimum loan is $1,000.

The proposed layout of the new building.

So the skinny on the expansion in case you hadn’t heard … The new space is a five-fold increase from the current space and there are plans for a mezzanine level cafe, a classroom and rooftop gardens and behives. The folks at Mariposa say that the added space will help them scale up their purchasing volume and keep prices relatively low. The added space will also mean that the co-op will be able to serve non-members, though membership – the lifeblood of Mariposa – will still be encouraged.

A date has not been set for the opening of the new building.
