Stormwater runoff is what washes off of parking lots, roadways and rooftops when it rains. Eve Brantley, associate professor of crop, soil and environmental sciences at Auburn University, said it may sound harmless, but it has a big impact.
“I just feel like it’s the forgotten pollution,” Brantley said.
She said part of the problem is that stormwater picks up other pollutants like trash and fertilizer. The other issue is the sheer volume of runoff that is discharged into area waterways.
Cahaba Riverkeeper David Butler sees the impact on a daily basis.
“So we’re pushing so much water into the river so fast now that, you know when it rains, instead of soaking into the ground, it’s all channeled to the river,” Butler said. “So it rises really quick, falls really quick, and you get a lot more erosion like this.”
He said all along the river, large sections of the bank have collapsed, often during rainstorms. This strips away vegetation that normally acts as a buffer, leaving dirt to erode into the river and fill it with sediment. Read more.
Cahaba Riverkeeper David Butler often has to convince people that sediment can be a problem.
“You know rivers are remarkably resilient,” Butler says. “They can handle a normal amount of mud.”
But he said the amount of mud in the Cahaba is not normal. Walking along a section of the river in Hoover, Butler leans over and scoops up a handful of rocks.
“So if you see how much dirt there is in it,” he says, “there’s not a lot of space in between the rocks for bugs and mussels and snails to live.”
Butler said it is now more common to see large mounds of dirt and gravel that pile up in the middle of the river, the result of sediment pushed downstream. Over the years, he said, parts of the river and its tributaries have accumulated as much as 20 feet of extra sediment.
The Birmingham City Council appears set to oppose construction of the controversial Cahaba Beach road and bridge project across the Little Cahaba River.
The Little Cahaba flows from the Lake Purdy reservoir a quarter-mile upstream from the project to the larger Cahaba River, where the Birmingham Water Works Board takes water for treatment.
A majority of council members, meeting as a committee-of-the-whole on Monday, voted to recommend against connecting Cahaba Beach Road off U.S. 280 to Sicard Hollow Road in Shelby County and to the Liberty Park development in Vestavia. The vote included a total of seven council members, President Valerie Abbott among them. A full council vote is set for Nov. 20.
Representatives of environmental groups at the meeting said the road is an “unnecessary convenience road for a few” that “should not outweigh the risks to the quality and cost of a main drinking water source for 600,000 people.”
The Alabama Department of Transportation and Shelby County engineers are pushing to extend Cahaba Beach Road across a new bridge to Sicard Hollow Road in Shelby County. Representatives of those entities did not attend Monday’s meeting.
Traffic authorities seeking to extend a road across the Little Cahaba River in southern Jefferson County promised Tuesday to make it a controlled access road and prevent adjacent development in the watershed that protects metropolitan Birmingham’s drinking water supply.
But clean-water advocates poured into a public meeting Tuesday night to insist the risk of contaminating the river even from road and bridge construction outweighs the convenience of connecting Cahaba Beach Road to Sicard Hollow Road. Multiple environmental organizations are urging residents to lobby the state to drop the project.
The project would create a more direct route from U.S. 280 to future Liberty Park development and Grants Mill Road for an estimated 10,000 vehicles a day by 2025. But is not intended to reduce traffic on commuter-congested 280, according to DeJarvis Leonard, Birmingham region engineer, Alabama Department of Transportation. Read more.
The ongoing fight over extending Cahaba Beach Road from U.S. 280 across the Little Cahaba River will heat up with another public meeting scheduled for Tuesday.
Highway engineers will present an update from a meeting a year ago concerning the project’s impact on the river. The Little Cahaba is a vital link in the area’s drinking water supply, connecting the Lake Purdy reservoir to the main Cahaba River.
Environmental groups are rallying forces with the intent of preventing the estimated $10 million to $20 million project of the Alabama Department of Transportation. The department announced it would present a modification of the plan floated a year ago. The Cahaba River Society, Cahaba Riverkeeper, Alabama Rivers Alliance and Southern Environmental Law Center have joined to object to it.
The public involvement meeting will be from 4 p.m. to 7 p.m. at Liberty Park Middle School, 17035 Liberty Pkwy. ALDOT representatives and project designers will be available, with maps of proposed routes, to answer questions. Interested persons can make verbal and written comments on the project and indicate preference for a route or no route. Read more.
The river runs through it – the “it” being the undeveloped areas adjacent to the Little Cahaba River. But will a new road also run through this pristine watershed that protects the quality of a major source of drinking water for most residents of Jefferson and Shelby counties?
The Alabama Department of Transportation is taking written comments from the public until Nov. 1 on whether to widen and extend Cahaba Beach Road from near U.S. 280 across a new bridge and connect it to Sicard Hollow Road.
ALDOT regional engineer DeJarvis Leonard said the cut-through project would take many years to complete but would improve access between roads on either side of the Little Cahaba River and reduce travel times.
Environmentalists’ concerns include potential degradation of drinking water by the construction, traffic and potential future commercial development. They also point out the river is a prime recreation area for canoeing, kayaking and hiking. Read more.
The Alabama Department of Transportation will discuss its proposed route for a bridge across the Little Cahaba River during a public meeting Tuesday, Oct. 17.
Environmentalists have opposed the proposed extension of Cahaba Beach Road across the river, saying the construction and potential development of the pristine area could threaten the health of a major source of drinking water. Read more.
