From the Ground Up - A Grassroots Approach to Stormwater Management

When:  Wednesday, June 11, 2014


Overview:   Stormwater runoff poses a significant threat to Vermont’s waterways from both a water quantity and water quality standpoint.  The sheer magnitude of stormwater related issues throughout the state requires a certain level of regulatory control.  But regulation alone will only get us so far.  Education, outreach, technical assistance, financial incentives, and voluntary implementation are also needed.  Luckily, local organizations are making a concerted effort to provide these services to citizens and communities alike.  In this webinar, we’ll hear from some of the people and organizations who are pushing for better stormwater management at the local level.  Presenters will highlight successful projects and initiatives, discuss challenges, and answer questions from the audience.  Take advantage of this opportunity to learn about some great programs and initiatives being undertaken at the local level.

Raising the Bar: Green Stormwater Infrastructure Planning and Design

When:  Tuesday, April 22, 2014 - Wednesday, April 23, 2014


Where:  DoubleTree Hotel by Hilton in South Burlington

Overview:   Please join us for a two-day intensive workshop focused on the use of green stormwater infrastructure (GSI) systems and practices to achieve stormwater management goals.

Stormwater runoff, caused by precipitation running off impervious surfaces and developed lands, is a leading cause of surface water pollution. Managing the quality and quantity of this runoff is of utmost importance for the health of our communities and the protection of natural resources.

The workshop will include an overview of why and how the national stormwater world is shifting to place more focus on volume reduction, small-scale practices close to the source of runoff, and green practices that utilize soils, vegetation, and natural processes to reduce the volume of and remove pollutants from stormwater. Presentations on green stormwater design practices and principles will be included, as well as a hands-on site design charette using real-world site plans from Vermont. This charette will give participants experience with applying green practices to sites that utilized more traditional approaches, but where there were missed opportunities to apply green practices. The workshop will also include a session on implementation strategies and challenges for Vermont.

The Green Infrastructure Portfolio Standard

Presented by Hal Sprague, Manager of Water Policy, Center for Neighborhood Technology

When:  Thursday, October 31, 2013


Overview:  The Center for Neighborhood Technology (CNT) is a 35-year old organization that develops tools and methods for sustainable economic development. In 2012, CNT developed a new way to manage stormwater in developed urban settings: the Green Infrastructure Portfolio Standard (GIPS). The GIPS takes a cue from the popular Renewable Portfolio Standard and Energy Efficiency Portfolio Standard policies enacted in many states across the country to encourage renewable energy and energy efficiency use, respectively. The GIPS is intended specifically to help  developed areas scale up green infrastructure practices cost-effectively, since stormwater regulations that apply only to new developments or redeveloped sites are inadequate for this purpose.

For too long, stormwater runoff has been treated as a nuisance and a waste to be disposed of, rather than a vital asset to be managed carefully. Cities that thrive in the future will make better use of such important resources, in turn providing more benefits to their residents and businesses and reducing the costs of living and doing business.

Hal Sprague from CNT provides a detailed overview of the GIPS and how it’s being used.

About the Presenter:  Hal has been at the Center for Neighborhood Technology, in Chicago, since May 2008, and is Manager of Water Policy at CNT. He researches and promotes policies that increase the use of sustainable water management strategies and practices in urban communities, such as water conservation and stormwater green infrastructure. Hal earned a master’s degree in Water Resources Management from the University of Michigan and his law degree from the University of Colorado. Prior to joining CNT, Hal practiced environmental law for 23 years, including positions at U.S. EPA, a major law firm, and a multinational corporation.

Valuing Green Infrastructure: Economic, Environmental, and Social Benefits

Presented by Hal Sprague, Manager of Water Policy, Center for Neighborhood Technology

When:  Thursday, September 26, 2013


The Center for Neighborhood Technology (CNT) is a 35-year old organization that develops tools and methods for sustainable economic development. In 2011, CNT and American Rivers developed “The Value of Green Infrastructure: A Guide to Recognizing Its Economic, Social and Environmental Benefits.” The guide is a tool that municipalities can use to quantify the multiple economic, environmental, and social benefits provided by green stormwater infrastructure (GSI). Municipalities have often struggled to quantify GSI’s monetary benefits. However, any cost-benefit analysis comparing gray infrastructure with GSI is incomplete if it fails to factor in the multiple benefits that only GSI uniquely delivers. These benefits are above and beyond the basic stormwater control benefits, which are assumed to be equal to a similar investment in gray infrastructure. “The Value of Green Infrastructure” brings together current research on green infrastructure performance and presents methods for calculating related benefits in water management, energy, air quality, climate, and community livability.

Hal Sprague from CNT will walk us through the development of the guide and how it can be used to promote greater GSI implementation in Vermont cities and towns.

Using i-Tree Hydro to Model Green infrastructure

Presented by Ted Endreny, Ph.D., P.H., P.E. and the ESF Team

When:  Thursday, June 27, 2013

Course Overview:

i-Tree Hydro is a stand alone application designed to simulate the effects of changes in tree and impervious cover characteristics within a defined watershed on stream flow and water quality. It was designed specifically to handle urban vegetation effects so urban natural resource managers and urban planners can quantify the impacts of changes in tree and impervious cover on local hydrology to aid in management and planning decisions. Researchers at the State University of New York in Syracuse are using i-Tree Hydro to model the hydrologic impacts (water quality and quantity) of green infrastructure. Green infrastructure includes a variety of methods such as rain gardens, bioretention basins, and green roofs used to capture, infiltrate, and transpire rainfall and runoff. Using predominantly natural processes, green infrastructure can clean water, restore soils, landscapes, and receiving water, improve air temperature and quality, and fortify and sustain our economy.

About the Presenter:

Ted Endreny is a professor in the SUNY ESF Department of Environmental Resources Engineering in Syracuse, NY. He has a PhD in Water Resources Engineering, a MS in Agricultural and Biological Engineering, a BS in Natural Resources Science, and licensure as a Professional Engineer and Professional Hydrologist. He has been a developer of i-Tree Hydro and other i-Tree tools through his research partnership with the USDA Forest Service. Endreny teaches and mentors students in engineering methods to monitor, model, and restore natural resources for the sustainable provision of needed services while addressing population, land use, and climate change pressures. Endreny’s ESF Team uses environmental resources engineering to help communities plan, design, and manage for water, food, energy, and health security. The ESF Team includes Ph.D. students Tom Taggart and Emily Stephan.

Site Design Using Green Infrastructure & LID Techniques

Presented by Donald W. Lake, Jr., P.E.

When:  Wednesday, August 17th 2011

Where:  Capitol Plaza, Ethan Allen Room - Montpelier, VT

Thank you to all those who attended and made this workshop a success!

Course Overview:

Recently, improved site development techniques have been created to improve water quality as well as to reduce discharges from development sites. Many state stormwater management manuals have been revised to include details on stormwater management planning using Low Impact Development techniques, and Green Infrastructure Practices. The purpose of these changes is to incorporate better planning techniques combining with source control practices to reduce pollutants in stormwater runoff by getting closer to the source. These concepts and practices will also reduce the amount of runoff by providing enhanced infiltration, adsorption, and storage, to mimic pre-development hydrology for the most frequent storm events.

This course will take participants through the planning process using the green infrastructure planning practices outlined in the design manual for actual site examples. The participants knowledge of preservation of undisturbed areas, buffers, reduction of clearing and grading through better site orientation, identification of sensitive areas, utilization of open space design, and providing soil restoration, will be enhanced with specific site examples. Impervious cover reduction practices will also be reviewed.

The integration of green infrastructure runoff reduction practices will be demonstrated on actual site situations to achieve the goals establi! shed in the Vermont Stormwater Management Manual. Detailed sizing exer cises of some of the most popular treatment practices such as rain gardens, roof disconnection, vegetated swales and porous pavement, will be performed by course participants.
