The Meaning of Hahamongna

The original settlers of the region were sometimes called the Hahamongna Indians. The word means "Flowing Waters, Fruitful Valley" in the native Tongva language.

Re: “LCF gets the dirt on Devil’s Gate,” Oct. 23. The original 2011 plan called for removal of 1.67 million cubic yards. The draft environmental impact report doubled this to 4 mcy. Last May the Pasadena City Council unanimously approved a plan of 1.7 mcy by the Sediment Working Group that proposes an agreement with the county to achieve and maintain a capacity in the Hahamongna basin for 2.5 mcy of sediment with no more than 220,000 cy removed per year, except after large storm events. This would ensure flood protection while minimizing impacts. The difference between the DEIR and this proposal is that it takes place over a longer period of time with less traffic, less pollution, cleaner trucks, fewer hours and time span of operation, less destruction of habitat, and greater sensitivity to the needs of the surrounding schools and communities.

The final county plan takes place over five years from April to December with 50 trucks an hour and 425 trucks a day to remove 2.9 mcy. Trucks will use Windsor Avenue during drop-off and pickup times at La Cañada High School, and otherwise use Berkshire Avenue to exit. This plan does little to alleviate the pollution from dust or diesel. Our schools near the 210 Freeway will have increased exposure to diesel pollution. Studies have documented a link between diesel pollution and increased risk of asthma, cardiovascular disease, respiratory disease, adverse birth outcomes, autism, and premature death. Infants, children, the elderly and people with heart or lung disease are at higher risk of harm from this particulate pollution. The World Health Organization states air pollution is a carcinogen, with greater impact than second-hand smoke as a trigger for cancer.

I would like to see the county of Los Angeles and La Cañada join with Pasadena and approve the Sediment Working Group plan.
