Red-dirt dam across Aspen Bayou entry



Last week, workers built a dam of red dirt across the south-central entry to the portion of Aspen Ridge that is dug out for a street for access to the intersection of Eleventh Street and South Duncan Avenue. The dam is supposed to protect Don Hoodenpyle's makeshift driveway that comes from the north in the old Duncan Avenue right of way. It also needs to protect the Town Branch of the West Fork of the White River from stormwater runoff.

Unfortunately, the red dirt itself is already being tracked onto the streets as vehicles exit the Aspen Ridge site. Additionally, the red mud will wash off the top of the dam and into the tributary of Beaver Lake when even minor amounts of rain fall.

One solution might be to cover the red dirt with gravel and pack it down into the red dirt well enough to reduce the erosion. However, there is no simple and easy way to guarantee that serious erosion resulting in further pollution and siltation of the Town Branch will not occur when the next heavy rain comes.

How does a red dirt dam keep red dirt from flowing into the creek?

It doesn't. Red dirt used in streets and foundations is about the worst kind of silt to send to a stream. It has little or no organic content and nothing can grow or live in it, plant or animal.
