PWCA Comments on Virginia’s Phase II Chesapeake Bay Water Improvement Plan

Over the last 300 years, Prince William County has damaged its streams and polluted its waters. We have removed the natural forest cover, used creeks as sewers for sewage wastes, and piped excessive runoff from our roads directly into our waterways.

Not surprisingly, many of our lakes and streams are classified as “impaired” by the Virginia Department of Environmental Quality.

The Clean Water Act requires us to restore our natural streams to “fishable and swimmable” status.  If we clean up the local waterways, then Prince William also will do its part to restore the Chesapeake Bay. After all, polluted water from Prince William flows downstream via the Potomac River to the bay. The solution to Save the Bay is for every jurisdiction upstream, even in West Virginia and New York, to clean up their local waterways.

The legal deadline to restore the health of the Chesapeake Bay is now the year 2025, so we have about a dozen years to finish the job that we started when Virginia signed the Chesapeake Bay Agreement in 1983. Continue reading

Stream Stewards – Temporary streams help save the Bay

Jake Hosen, University of Maryland, gave a great talk on streams and what keeps them healthy on Thursday night (4/4), and followed it up Saturday morning with a guided walk through the flood plain of Cedar Run on Merrimac Farm to view the streams there.

Streams that flow year-round are known as perennial streams, while temporary streams have no water flow during some portion of the year.

There are two types of temporary streams. The first are intermittent streams which do not flow year round but are fed by groundwater during some portion of the year. The second type, ephemeral streams, receive water only from rain and never from groundwater so they usually flow less often than intermittent streams.

It turns out that streams are not only lovely to look at, they have many interesting characteristics. Streams are ubiquitous – there are approximately 1.6 million miles of 1st order streams, which are the smallest streams in a river network. Overall, in the continental United States and Hawaii a remarkable 59% of stream length is estimated to be temporary. Continue reading

The One Stream at a Time Tour

by Terry Reardon

Last Sunday (3/25), the Prince William Conservation Alliance’s first session of the Stream Stewards program kicked off with an eye-opening tour of two badly damaged streams, one in Hylbrook Park and the other half a mile away off Route 1 (view photos here). Both streams are high priority restoration candidates that illustrate the opportunities and challenges for Prince William County to protect local water quality and help save the Chesapeake Bay.

After remarks by County Supervisor Mike May about the challenges the county faces in restoring already damaged water resources and working to prevent future damage, County Environmental Engineer Clay Morris began by pointing out the Hylbrook Park stream’s precarious location in a heavily developed section of Woodbridge.

Morris pointed out several factors that would hinder the restoration of the stream that may not be immediately obvious to the lay conservationist. For example, there is only a narrow strip of ground on either side of the stream in which to work, leaving no space for the necessary easements, or an area for staging the restoration work. Most importantly, there is no room for the engineering of the stream bed to allow it to properly channel the large volume of water that rushes between its banks during a storm. Continue reading

Virginia proposes end to participation with multi-state Commission aimed at protecting Potomac River

The Interstate Commission on the Potomac River Basin (ICPRB) is an interstate agency created by the individual statutes of its member jurisdictions – Pennsylvania, Virginia, Maryland, West Virginia, and the District of Columbia. Federal Government participation was approved by Congress in 1940.

The ICPRB promotes collaborative watershed-based services aimed at improving and protecting water quality and quantity in the Potomac River basin. The ICPRB provides services that directly benefit Virginia, including technical and managerial support, watershed-based initiatives with an intergovernmental focus and public education.

Virginia’s cost for continued participation with the ICPRB is $151,500. The return on this investment is significant. In 2011, the total cost benefit to Virginia provided by ICPRB services totaled $529,000. (Click here for supporting documents.)

According to Fairfax Water Authority (FWA), “Northern Virginia, an economic engine within the Commonwealth, would be adversely impacted by Virginia’s withdrawal from the ICPRB.” FWA has expressed concern that “withdrawing Virginia’s membership from the ICPRB could have serious consequences for regional cooperative water supply operations and could jeopardize the reliability of the Potomac River as a water supply source during droughts.” Continue reading

Going Native!

By Terry Reardon

Invasive plants are destructive and virtually impossible to remove once they become established.  Look at a kudzu-draped forest or a waterway choked with hydrilla. These invasives are killers, cutting off oxygen and sunlight to native plants, weakening them and eventually outcompeting them. Millions of dollars are spent annually trying to eradicate invasive plants without success.

Another type of costly invasive that we’re all familiar with—and even nurture—is grass.  Many of the varieties in our lovely green lawns are not native to Prince William County, Virginia, or even the United States. For example, Kentucky bluegrass, despite its name, originated in Europe, Asia and northern Africa.

There are several significant drawbacks to the maintenance of a sweeping expanse of grass. The custom of growing a luxurious lawn originated in England, where there was sufficient rainfall to support the native plants. Many areas of the US are too dry to cultivate a large area of non-native grasses without using a huge amount of water—50 to 70 percent of residential water use in the summer. Continue reading

PWCA Comments on the Fairfax Water Authority Occoquan Reservoir Shoreline Easement Policy Update

Fairfax Water Authority is holding a public hearing for the draft changes to their Shoreline Easement Policy on Thursday, February 3, 6:30 pm at the Fairfax Water Board Room, 8570 Executive Park Avenue, Fairfax. Email written comments to ShorelinePolicy@fairfaxwater.org by February 2.

The Prince William Conservation Alliance strongly supports efforts to protect clean drinking water in the Occoquan Reservoir. The proposed changes to Fairfax Water Authority’s Shoreline Easement Policy emphasize opportunities to prevent damages, avoid costly mitigation needs and benefit all Fairfax Water Authority ratepayers.

The increased standards proposed in the update represent a positive step forward. However, we believe additional efforts to establish specific standards for restoration following disruption (willful violation) of the easement would significantly improve Fairfax Water Authority capacity to implement the policy in a fair and consistent manner.

The policy should be specific regarding both prohibited activities as well as standards for restoration where violations occur. Mitigation requirements for violations involving shoreline alteration, including filling (soil and other), surface alteration (mulch and other), and the removal of vegetation should be clearly described.

After 27 Years, EPA Defines Pollution Limits for Chesapeake Bay “TMDL” (Anticipated Cost in Prince William: Perhaps $300-350 Million)

Chesapeake Bay water quality is impaired because water flowing off urban/suburban areas and farmland is carrying too much nitrogen, phosphorous, and sediment downstream.   The bay is not healthy; we have dramatically damaged the populations of blue crabs, oysters, striped bass…

The sediment smothers oysters and clouds the water, killing underwater grasses and reducing food/habitat for aquatic life.  The nutrients (nitrogen and phosphorous) cause damage by triggering excessive growth of algae.  When the algae finally decays underwater, oxygen is depleted and everything dies in “dead zones.”

The Chesapeake Bay can absorb some pollution, but we have overloaded its capacity to handle the three major pollutants.  To solve the problem (and bring the bay into compliance with the Clean Water Act), the Environmental Protection Agency (EPA) has determined the Total Maximum Daily Load (TMDL) of nitrogen, phosphorous, and sediment that each state can send downstream to the bay.

The TMDL limits issued by EPA today establish a “pollution diet” that will require a 25 percent reduction in nitrogen, 24 percent reduction in phosphorus and 20 percent reduction in sediment.   In Prince William County, the main source of that pollution comes from stormwater than runs off our roads, parking lots, rooftops, and over-fertilized lawns.

According to Wetland Studies and Solutions, a local firm with expertise in stormwater management, Prince William County may have to spend roughly $20-25 million/year, perhaps $300-350 million over the next 15 years to implement Best Management Practices (BMP’s) that control excessive locally-generated stormwater pollution.

Current and future residents will pay a high price now for three decades of county officials who approved blast-the-landscape developments that destroyed small intermittent streams, damaged larger perennial streams, and replaced forests with pavement without requiring streamside buffers to minimize pollution running into our creeks.  Continue reading

Round 1 goes to polluters

The majority of Supervisors approved developers 11th hour changes to the County’s new environmental policies… signaling their support for higher taxes this spring (and removing any doubt about who’s really in charge here).

Only two Supervisors disagreed – Mike May (Occoquan) and Frank Principi (Woodbridge) both supported the staff recommendation, which would have (1) discouraged development on slopes prone to landslides, (2) protected many intermittent streams, (3) raised the bar for stormwater runoff and (4) help save the Chesapeake Bay.

The standards recommended by staff would have helped reduce tax increases this spring for both the County budget and the Stormwater Fee. Stay tuned for more information…

Name: Swan’s Creek

Impacts: Flooding of downstream properties as well as damages to Quantico Creek, the Potomac River and the Chesapeake Bay.

Source of impacts: Uncontrolled stormwater runoff from the construction of the road at Harbor Station development (Cherry Hill Peninsula)

Estimated costs to taxpayers to mitigate flooding of downstream properties: $1,000,000 (Upper Swan’s Creek Stabilization Project)

Staff Stands Firm; Supervisors Waffle

It was December 7 (Pearl Harbor day), so a last-minute surprise proposal to alter the Environment Chapter should have been expected after 18 months of public debate.

However, four county supervisors questioned the legitimacy of voting on a back room “compromise” that had been crafted in secret with just the developers.

The proposed changes to the draft chapter were revealed only after the public hearing was closed, ensuring no public review or comment – except the developers were given a special opportunity to speak after the public hearing was closed.  That’s fair and balanced, right?

The Board ended up deferring action on the last-minute changes, including the definition of significant non-RPA streams and the identification of areas with steep slopes, until December 14.

Do a little math in advance of that meeting:

  • Prince William needs to reduce existing stormwater pollution to meet the Total Maximum Daily Load (TMDL) standards for sediment, nitrogen, and phosphorous
  • Prince William’s population is projected to grow by 33% over the next 20 years, adding even more pollution
  • a Federal judge is requiring EPA to enforce the Clean Water Act standards (27 years after Virginia committed to Save the Bay)

And we should do… nothing?

Prince William Can Lead On Immigration, But On Environmental Policy… We Gotta Wait For the Feds to Fix It?

The Board of County Supervisors has had no problem asserting its perspective on social issues that involve state/Federal responsibilities, including immigration and abortion.  County officials have already rejected the “wait for the Feds to fix it” philosophy.

However, the Northern Virginia Building Industry Association (NVBIA) is proposing in a November 29 letter that the county postpone a decision on the Environment Chapter.  The NVBIA recommends that the Board of County Supervisors abdicate its responsibility to set policy for new development.  NVBIA proposes that Prince William do nothing until the Environmental Protection Agency (EPA) and state agencies tell us exactly how to reduce locally-generated stormwater that pollutes our drinking water supplies and ultimately the Chesapeake Bay.

The supervisors know that the Comprehensive Plan is a big-picture policy document.   Why should the BOCS delay saying the Prince William values clean water, and that new development should protect our existing streams?   If we delay delay delay until the Feds finally impose mandatory controls so Prince William complies with the Clean Water Act, local officials will lose flexibility in making future land use decisions.

Developers benefit from the current “build anything, anywhere” policy.  However, if supervisors wait for that interest group to give the green light for environmental protection, they probably think people in Hades need ice skates.
