Lagoon Proposal Aired

SAN DIEGO —  The possibility that the ports of Los Angeles and Long Beach will preserve and develop a lagoon between Interstate 5 and El Camino Real in the San Dieguito River Valley received its first public airing Wednesday. The proposal, which has been quietly discussed in government and private circles for nearly a year, would have the two ports, which want to double the size of their facilities in San Pedro Harbor, offset the environmental damage they would cause there by developing--at their expense--a wetlands habitat just east of the Del Mar Fairgrounds.
