Correspondent of the Day:torm Water Laws Provide Many Benefits
Stormwater Laws Provide Many Benefits
Editor, Times-Dispatch: How we can spend billions of dollars for research on energy and resource conservation, yet every time legislation is proposed to put new technology into practice, someone says it will cost too much or it isn't what is needed? The opposition is based more on what political contributors want -- to protect their profit margins without regard for the long-term benefits to the general population.
Opponents suggest the most expensive way is the only way and will only achieve limited results. Such is the case regarding the new stormwater regulations. They talk as if only the Chesapeake Bay will benefit (as if that was not enough). In fact, every water resource will benefit. The better the quality of source water, the less it costs to process for consumption.
Some would have us believe the regulations will add thousands to the cost of new homes. In reality, capping gutters and running flex pipe underground from downspouts to the storm drain would only cost a couple of hundred dollars. This alone would eliminate runoff from lawns and landscaping.
Commercial and higher-density areas present different challenges to handle runoff water. Structural best management practices (BMPs) need not be stagnant collection pools; they can be incorporated as water features with fountains -- allowing a more natural ecosystem that controls some of the undesirable side effects of BMPs. They can be used for landscape irrigation and could be solar-powered. The initial cost is easily recovered in utility savings over a short time. Many things could be done, but people aren't willing to make the changes needed to preserve the future.
With population growth and increased demand on our water resources, it is time to be proactive. Being reactive is more costly and being late will be fatal to both business and future generations.

To put it simply, runoff from the roofs does not run through landscaping before it enters the drainage system, thus reducing the volume of water washing through lawns and landscaping. It also would dilute any pollutants that do wash out of the landscaping, and increase the volume required to create a washout effect. The science on how it works was edited out do to space limitations. Granted commercial developments present other challenges and municipalities need to acknowledge the efforts of the development community after all it would help reduce the operating costs in the utility department. Yes work needs to be done regarding the farming communities role, but that is not what this legislation is about. Just because there is work to do in one area is no reason not to start in others, that excuse is childish, political and exactly we don’t seem to get things done that need to be done.
First off, I’m unsure how capping gutters and running HDPE pipe to the stormsewer system under the street is going to eliminate “runoff from lawns and landscaping”. When it rains, there is still water falling on the lawns and landscaping and then sheet-flowing somewhere while carrying fertilizer. Second, you would be increasing the amount of rainfall from impervious area (roofs) that is being directly discharged into the stormsewer system…which then must increase the size of the downstream BMP (usually a pond, which has been proven to be the cheapest method) and thus the cost.
And finally, while it sounds nice to have BMPs that are “solar powered” and used to irrigate lawns, these solutions require a large amount of meticulous planning, design, time, material cost, and increased maintenance. All of which add considerable amounts to the bottom line and provide little, if any, benefit to the Bay or nearby water systems.
Bottom line is that development contributes a mere fraction of pollutants to Virginia’s waterways that come from our agricultural practices, where runoff from large, open, heavily-fertilized acres enter our waterways directly. But I assume private developers don’t have quite the lobbying power or “little guy” appeal that farmers do.
