New Video Highlights Environmental and Economic Benefits of Conservation Design

January 28th, 2010

Delaware County, PA — There is far more to creating a quality residential development than grading a property and putting up homes. Conservation design looks at natural features, site constraints, and stormwater management — long before construction begins.

When Trilogy Investments bought one of the last remaining large parcels of property in Thornbury Township, they envisioned building 458 residential units on large lots throughout the tract–exactly what the township’s zoning allowed. When Trilogy’s President John Lynch saw that the township had other hopes and concerns–and was willing to be flexible in finding a solution that was beneficial to all–he realized it was a whole new game. The Cherry Creek cluster development became a model of conservation design that preserved woodlands, wetlands, and fields — and ended up holding 241 homes.

Says John Lynch:

I guess there’s a question of whether I’m doing this type of development for altruistic reasons or not. The answer is I’m not. First and foremost it’s a business. So normally when I  get involved in new projects, I look at them pretty analytically–what are my rights under law–and I then try to do better. When there are people on the other side of the table who share the goal of doing something better, so that there’s a win-win scenario, then it’s all green lights and I will pursue that with more vigor and more gusto than you can imagine…

Measure Your Impacts, Do it Yourself Runoff Control, Stay Up-to-date on BMP Research

December 8th, 2009

The Montgomery County Conservation District web site offers several Do-It-Yourself Rain Collection projects.  Check out their information on making rain barrels and rain gardens.

The Chesapeake Bay Foundation has created a tool to help you Measure Your Bay Footprint so you can compare your nitrogen footprint with the average in the Chesapeake Watershed. Visit CBFs Nitrogen Calculator.

From The Journal of Hydrologic Engineering: Is Impervious Cover Still Important? A review by Tom Schueler, Lisa Fraley-McNeil, and Karen Capiella of recent research on the Impervious Cover Model (ICM) shows that research since 2003 has confirmed the basic premise of the ICM–but has also revealed important caveats.  For the abstract and the full article, go here.

BMP Manual Revision Committee Sub-Group D: Capture and Reuse

October 6th, 2009

As previously noted in our September posts, PA DEP has convened a BMP Manual Revision Committee. In their notification to attendees, they noted that

… recommended updates may include edits to existing portions, complete omissions, or additions of new material.  All changes much be justified through acceptable principles of engineering or science.  If unable, to do so, subgroups may bring new ideas before the bigger committee for consideration and feedback.

Following is PA DEPs statement on the focus of this  Sub-Group, as presented at the first Committee Meeting:

Capture and Reuse (C&R) is one of three volume control alternatives offered by the BMP Manual, however there is no guidance given on how to equate volume and peak attenuation for these measures.  There have been some different approaches on this topic from across the state that can hopefully be considered as part of this endeavor.

Modeling approach:

Event-based modeling (w/ longer dewatering time - up to 7 days)   or  annual water budget approach?  Which is best?  Can criteria be given for both.  (Also see Subgroup Topic B)

Questions:

  • How can a private residence take into account a rain barrel or cistern?   Should a bleeder hose into a vegetated area be mandatory in order to receive credit?
  • Can treated sewage (effluent) and stormwater runoff be utilized together for land application?   Can they be stored together?
  • What other creative ways can C&R be utilized into a typical land development project?   Can this water be bled into vegetated systems such as a rain garden during non-wet weather?

Subgroup should develop a thought process for C&R Projects since many practitioners are not used to incorporating them into their designs.

For starters, here are some typical steps that could be followed:

  • The first step would be to identify the type of water reuse (residential, commercial, golf course, industrial, etc.).   Is the project laid out in a manner that makes C&R feasible?   Is there sufficient space/topography for both storage and application of stormwater?
  • The second step would be to determine consumptive use (or reuse).   What are the variables?  Does this vary by day, week, month or season?
  • The next step would be to determine the application rate.  For land application, this would depend on soils, topography etc.

Watershed Education in Chester County, School’s “Attack on Asphalt” Helps Philadelphia with Stormwater Overflow Problems

June 22nd, 2009

The Buck and Doe Run Watershed Partnership in Chester County has created a watershed education pamphlet titled “Welcome To Your Watershed” for interested residents in the watersheds. The pamphlet details the watershed boundaries, suggests different, simple conservation practices, additional education resource agencies, and cultural/historical attractions in the region.  More information.

Read how one elementary school is combating Philadelphia’s stormwater “overflow” problem  in Changing Skyline: Attacking Asphalt by Inga Saffron of The Philadelphia Inquirer.

Upcoming Events

July 20th-24th, 2009: 13th Annual Delaware Estuary Watershe Teacher Workshop. This week-long workshop is designed to give participants a greater understanding of the wide variety of issues within the watershed and the interconnections between human actions and the river’s ecosystem. Begin the week at the upper portions of the estuary and literally travel down to the mouth of the Delaware Bay, ending with an overnight in the historical beach town of Lewes, DE.  See brochure for more information and registration form.

REMINDER From the Villanova Urban Stormwater Partnership website:

Brandywine Conservancy Partners with StormwaterPA

March 30th, 2009

Flood prevention, improved water quality, economic benefit, and better quality of life just some of the goals of helping municipalities transform the way they manage their rainwater.

March 30, 2009, Philadelphia, PA—

Stormwater runoff causes flooding, erosion, habitat destruction, and it endangers human health. In Pennsylvania, stormwater runoff is the number two cause of water quality degradation, behind only acid mine drainage, and it is a major source of nutrients, sediments, and other pollutants to important waterways like the Delaware River and Chesapeake Bay.

In theory, Pennsylvania should have made great strides in the way it manages stormwater runoff in recent years, but in reality, there’s a huge gap between the intent of the state’s Stormwater Program and the application of its planning, preventive, and mitigation techniques. Why? The responsibility for managing stormwater in Pennsylvania lies within more than 2,550 municipal jurisdictions. Each has local decision-making authority. And the understanding of stormwater issues, regulations, and requirements is, quite literally, all over the map.

As a result, a virtual “revolution” in thinking about stormwater that emerged with the 2007 release of DEP’s Stormwater BMP Manual is being taken very seriously in some parts of the state but far less so in others. A pair of non-profits working on the issue have joined forces to change that by increasing the visibility and reach of an innovative awareness-building campaign known as StormwaterPA.

“We believe this partnership is a win-win for all of us working to protect the Commonwealth’s water resources,” says Barry Lewis, Executive Director of GreenTreks Network, the Philadelphia-based communications group that created StormwaterPA, “and it comes at a critical time.” Important environmental education and outreach efforts are being threatened by the ongoing budget crisis. The state’s “Permit by Rule” proposal, say clean water advocates, short circuits the public process, eliminates much-needed technical vetting, and will negatively impact the Commonwealth’s rivers and streams.

“The StormwaterPA campaign aims to help the essential players in stormwater management better understand their legal responsibilities and the wide range of options available to them through an easy to use Online Resource Center,” says Lewis, “and through a series of video case studies that show real world examples of innovative solutions that are working right here in PA.” GreenTreks and the Brandywine Conservancy have just formalized a partnership that brings the Conservancy’s intimate knowledge of land and water resources to the project in advisory, oversight, and content development roles. “We’ve created an important set of initial tools for the stormwater community and the Brandywine team will help us continue to add value for those we are trying to reach. Their participation will take the project to a whole other level over the next year and a half…”

Interestingly, it was Wes Horner, Brandywine’s Senior Adviser for Water Resources, who first encouraged GreenTreks to focus its communications skills on stormwater while working on the BMP Manual under contract to the state. He was a Principal Planner at Cahill Associates at the time. “There has been a dramatic shift in how we think about stormwater runoff in the past few years,” says Horner, “and while we were delighted the state maintained a forward-looking approach in the final version of the Manual, we realized we had a lot of educating to do in order to bring the stormwater community up to speed. GreenTreks’ history of water focused awareness-building activities, proven ability to create great video programs, and creative approach to outreach made them the first place we turned.”

The first phase of the campaign was supported by the William Penn Foundation and Keith Campbell Foundation, and resulted in a multi-media Online Resource Center that makes information about Pennsylvania’s stormwater program more accessible than ever before. It also enabled the documentation of a video series of “stormwater success stories” showing some of the innovative approaches to runoff management that are taking place all across the Commonwealth.

“Our research showed that the municipal officials, engineers, and developers who are the stormwater decision-makers want to see real world examples of the BMP Manual’s concepts at work,” says Lewis. “We’re off to a great start, with videos looking at everything from converting a traditional stormwater basin into a more natural area to a group that is working to protect headwater streams; from some of the things farmers are doing to protect their local water supplies and livestock to a developer that planned an entire residential community with infiltration in mind.” The second phase of the project is gathering steam, with new video case studies and web features in development and a host of educational presentations lining up over the next several months.

The Brandywine Conservancy has a longstanding reputation in environmental stewardship and water resources management, with particular focus on stormwater management. The organization has recently launched a new water resources program, featuring efforts to promote innovative stormwater management practices throughout southeastern Pennsylvania which includes a more complete stormwater ordinance and demonstration projects focused on homeowners and residential developments. Horner, an advocate of comprehensive stormwater planning throughout a career that spans more than 30 years, and Sheila Fleming, Senior Planner who specializes in Conservation Design and is a member of the American Society of Landscape Architect, will lead the Conversancy’s efforts on the StormwaterPA project. They will review and enhance all areas of the existing website, help develop new content and tools, advise on future video case studies, and act as key contributors to a newly released StormwaterPA Blog.

“As engineers and planners, we can no longer afford to look at stormwater as a nuisance to be disposed of through systems of basins and pipes,” says Horner. “Runoff is a valuable resource that we need to keep in the water cycle—and that means managing it in a more natural way. It’s imperative that we accomplish as much education as possible quickly, and we believe StormwaterPA will make a huge impact. ”

Rea Monaghan, an Environmental Planner with the Bucks County Planning Commission, agrees. “StormwaterPA is an incredible educational tool,” said Monaghan after providing DVDs of the video case studies to dozens of municipal officials who participated in a local Stormwater BMP tour. “You did a great job of pulling together the regulatory information, resources, and case studies into a project that can be used extensively by homeowners, municipalities, engineers, and developers.”

Lewis says that what you see today on www.StormwaterPa.org is only a start.
