The Alvord Lake area, fronting on Stanyan and Waller streets, is a gateway to other sections of the park. Yet the homeless and drug users so dominate the area that many parents and other park visitors are often afraid to use it.

Under the concept developed by Joel Robinson, the city's recreation and park manager, the area would be transformed into a haven for family recreation, a place where people would roller-skate in the summer and ice-skate in the winter and kids would clamber over statues.

In the northern section, the plan calls for an in-line skating rink that could be converted into ice-skating in the winter. The area is designed to replace the ad hoc skating scene on John F. Kennedy Drive and would include terraced seating for spectators and a family picnic area.

At the southern end would be a skateboard and roller-skate park, complete with bowls and curving tracks so that, as Brown said, skaters ``can kill themselves if they choose.''

In the middle, Alvord Lake would get an amphitheater for puppet shows, mimes and other performances. Nearby would be a kids' playground with shapes of animals and storybook characters for younger children to play on.

Along Stanyan Street would be a broad pedestrian promenade. Parts of the area, if not all of it, would be closed off at night to prevent homeless people from moving in, said Donna Ernston, executive director of Friends of Recreation and Park, which helped develop the plan.

``We were really thrilled to hear that (Mayor Brown) had endorsed the ideas for the new east end,'' said Ernston, whose organization is midway through a highly praised restoration of the park's western end. ``It's going to make a huge difference for the way the park serves people.''

Brown said the $2.5 million project will be privately funded, and the city already has received a commitment of $500,000. ``We're already a long ways down the road,'' Brown said. The mayor did not identify the source of the $500,000.

``It's a fantastic idea, and it can be done by drawing on private funding,'' said Supervisor Susan Leal. ``There are foundations and corporations in town just dying to be asked'' to participate.
