Two New Initiatives to Save Hahamongna





Save Hahamongna


Save Hahamongna


Several months ago you signed the petition to Save Hahamongna. Since then there has been a lot happening regarding the fate of that rare treasure at the foot of the San Gabriel Mountains. There's no question about it: 2011 will be a year of decision for Hahamongna.

A massive sediment removal program of the County of Los Angeles threatens to strip the basin of its rare habitat and disrupt our neighborhoods.
Pasadena is forging ahead with an ill-conceived plan to add a parking lot and a soccer field to the center of the basin.

The Arroyo Seco Foundation is launching two initiatives to inform the public about the environmental riches of Hahamongna and how each of us can be effective in helping to save it for future generations. We urge you to take action again to save our environmental legacy.

Learn what the fuss is about and why we think Hahamongna is the most precious environmental treasure in our region. Participants in this free event will tour Hahamongna Watershed Park by foot and visit learning stations that will educate everyone about key elements of the area, including habitat, wildlife, water resources, birds and threats to nature. It will be fun, educational and motivational! You'll never forget this day.

Sign the Petition to Ensure a Full Environmental Evaluation

The County of Los Angeles has recently announced a plan to remove massive amounts of sediment and habitat from the Hahamongna basin, and they think they can do it without an Environmental Impact Report to involve local residents and stakeholders or to consider the most environmentally sensitive alternatives. Everyone else has to follow environmental law. Why not the County?

Pasadena, La Canada and Altadena will all be heavily impacted by the constant parade of 300-400 truck per day for three years and all the noise, dust and air pollution they cause. And when the County is done, they will have scoured a permanent fifty acre barren scar in the middle of the basin. Gone will be the willows and riparian plants that now grace the area, as well as the birds and wildlife that now thrive there.

Our cities can and should do something about this. They need to take the lead in protecting our neighborhoods and our environment. That's why the Arroyo Seco Foundation has just launched a petition to urge our cities to insist on a full review of environmental alternatives and the selection of the plan that is the most sustainable and environemtnall sensitive.

Here's something everyone who cares about the Arroyo can help with. This is a new petition that focuses on the need for an Environmental Impact Report. Sign the petition and urge your friends and neighbors to do so as well.
