The creek has lasted because it has not had ALL of the water and mud from the Quarry directed towards it for the past 80 years.
For at least 40+ years the Quarry site had a large pond visible from aerial photos on site that probably buffered and slowed the flow to Chimes. This pond was visible thoughout the seasons-the developers tried to argue this was only a winter anomaly.
The conditions have changed. Any possible remains of the pond has been buried and covered. Natural absorption was a key to naturally controlling runoff. They are and the plan is to eliminate any natural absorption with roofs, asphalt/concrete roads, driveways and culverts that direct all captured water to the concrete detention pond-again no absorption. The detention pond water outfall is the existing 39 inch pipe that goes under I580. Their plan was/is to have any "overflow to run down Edwards Avenue"-this is all in the public record that the City approved. Even if it flows down Edwards, we argued, it all ends up in the strorm drains that eventually discharge into Chimes Creek.
