The study concluded that the Boy Scout property, while posing significant ecological hurdles, offers the only remaining possibility for meaningful traffic relief in the area between the 71 and 57 freeways. The San Bernardino Association of Governments as well as the San Gabriel Valley Council of Governments Transportation Committee listed this study as their No. 1 priority of 51 items recommended by Four Corners. In fact, THCA offered to buy 46 acres of property from the Scouts, at market value, to keep viable the most probable road alignment from Chino Hills to the 57 Freeway. And the cost of such a highway is prohibitive. None of these roads were engineered to accommodate animals, and they don't.
Animals are mostly active at night.
To presume that a road engineered to accommodate wildlife would be more adverse than the existing roadways is nonsense. Ironically, it was State Highway Trust funds that were originally used to purchase land for the Chino Hills State Park. The Park's creation cut off all other possible roadway alignments, and has by default or design made the Boy Scout property -the only remaining traffic corridor alternative between the 71 and 57 freeways. We can have our traffic mitigation without additional houses. We can accommodate our wildlife as well as our humans.
