Did you every wonder why the southeast corner of Mission Bay has had no development?

From the San Diego Reader: Between July 1952 and December 1959, the City of San Diego operated a landfill in Mission Bay Park between Sea World and Interstate 5. For ten hours a day, seven days a week, city trucks hauled garbage to the 115-acre site — the sort of refuse you can see being dumped into the Miramar landfill. But during its operation, the Mission Bay landfill served as receiving grounds for millions of gallons of industrial wastes being produced by San Diego’s aerospace industry. In some cases, these toxic substances were buried in steel drums. Other times they were poured into unlined holes 15 to 20 feet deep, below the level of the groundwater. It is not possible to list the hazardous substances the city allowed to be dumped there. No cleanup of the Mission Bay landfill has been conducted. If anyone kept records of what substances companies were discarding there, the files have disappeared. After the permanent closure of the landfill in 1959, the memory of the toxic dumping seemed to vanish. The Reader continues on the planned hotel development in 1983: The city was concentrating on development on the Mission Bay site of what was to be one of the biggest hotels in San Diego County. Known as the Ramada Renaissance Resort, the project was to include 638 rooms, tennis courts, swimming pools, racquetball courts, restaurants, and banquet rooms. … One week before Ramada was due to sign the lease, a news announcement brought development plans to a halt. On July 20, 1983, a local television station reported the revelations of an anonymous source who claimed to have been a truck driver during the 1950s. According to subsequent newspaper reports, the source said he had dumped hundreds of barrels of the carcinogen carbon tetrachloride at the Mission Bay landfill. This wasn’t the first time someone had linked carbon tetrachloride to the old dump. … With the televised report of the truck driver’s allegations, pandemonium erupted. Ramada announced that construction plans would be put on hold until the hotel chain could be convinced that the property was safe.
