In California, most tidelands, including land reclaimed from tidal water, belong to the counties or municipalities, not to the state. For years San Diego and four other bayside municipalities-National City, Chula Vista, Imperial Beach, and Coronado-administered their waterfronts separately (map, page 120). It didn't work very well, so now they do it together through the Unified Port District. Motels, marinas, other businesses, if they are on the bay waterfront, pay rent to the Port District. Its tenants range from a pop corn stand to Convair, the missile maker. Bay rentals are increasingly profitable. The five communities used to give one cent of each tax dollar to the district for port maintenance and development; now they give half a cent. "We hope that within two years we will be off the tax rolls forever," said Port Director Don Nay. He and his staff take great pride in the cleanliness of the waters in their charge. No municipal sewage enters the bay; San Diego treats it, then pipes the effluent 2 /2 miles out to sea. Tests show that the thousands of yachts contribute negligible amounts of waste, and laws against littering and dumping are strictly enforced. As a result, the bay meets the high est health standards. The Port District also administers several Between honeycombed halves of a test model of a nuclear-reactor core, a gloved technician secures strips of copper foil in a laboratory of Gulf General Atomic.
