LOS ANGELES (CBSLA.com) — The arrival of the Space Shuttle Endeavour may be delayed, but the debate over its environmental impact on local communities is just getting started.

KNX 1070′s John Brooks reports the Los Angeles Board of Public Works has reached an agreement on how many trees can be cut down to clear a path for Endeavour and how many replacements will be planted.

A full house of both critics and supporters of the shuttle’s transport from LAX to Exposition Park were on hand as California Science Center officials pledged to double the number of trees that would be planted to replace trees that have been removed to clear a path for Endeavour.

Officials with the California Science Center offered to replant four new trees for every tree that will be displaced along Manchester, Crenshaw and Martin Luther King boulevards. The proposed number of trees that would be cut down has already been reduced from 250 to 122.

One resident said regardless of any agreement, she’s still opposed to the removal of any mature trees in her neighborhood.

“Our trees de-pollute, mature trees de-pollute 90 times more than young trees,” she said. “90 times more.”

The arrival of Endeavour was delayed after storm conditions forced the Shuttle – which was originally scheduled to leave Florida for Houston on Monday – to depart for Los Angeles no earlier than Wednesday, Sept. 19., NASA officials announced Monday.
