Permeable Pavements in Ontario: Design options, maintenance BMPs and proven performance

March 13, 12-1 pm EDT

Integrating permeable pavements into Ontario cities can help protect against extreme weather conditions by alleviating pressure on existing and aged infrastructure, while simultaneous restoring of natural processes and managing stormwater near to its source. This webinar will present an overview of the system components and design considerations for permeable pavements. Maintenance best management practices and Ontario-based performance data will be discussed. The permeable pavements systems provide stormwater treatment by reducing the event mean concentration and total pollutant loading of petroleum hydrocarbons, total suspended solids, metals and nutrients in stormwater. Permeable pavements provide opportunities to infiltrate stormwater and support recharge processes. Additionally, the pavement and underlying aggregate subbase/reservoir attenuates flows generating outflows that better mimic pre-development hydrologic conditions.

Philadelphia: Green City, Clean Waters

April 10, 12-1pm EDT

The City of Philadelphia’s Green City, Clean Waters is a ground-breaking stormwater management plan to improve water quality and create a healthier, more sustainable city through green infrastructure. The greening vision for Philadelphia is one that recreates the natural environment while transforming and revitalizing the city’s communities. Green infrastructure beautify streets and neighborhoods, improve air quality and increase property values.  Currently in its 4th year of implementation, the Green City, Clean Waters program is reshaping Philadelphia as a truly sustainable city, one that functions as a green machine with tangible ties to its land and water resources. 113 green infrastructure projects have been completed; hundreds more are in design or construction. Also, PWD has provided $14 million in grant funds to 37 retrofit projects on industrial properties, universities, churches, and other sites. The Philadelphia Water Department, along with its many public and private partners, are working cooperatively and strategically to establish Philadelphia as “the greenest city in the nation.”

Infiltration in low permeability soils: lessons from the Sustainable Technologies Evaluation Program

April 24, 12-1 pm EDT

How effective are stormwater infiltration practices at meeting water balance targets when the development site is on fine-textured, low permeability soil? Are there ways of designing them to maximize drainage performance? Without definitive answers to these questions, designers are left with a much smaller toolkit of Low Impact Development (LID) practices in such contexts, and none that compensate for the loss of groundwater recharge caused by site development. To help answer these questions evaluations of the performance of several infiltration systems located on glacial till soils in the Greater Toronto Area have been completed. Results prove that they can be effective at meeting groundwater recharge targets on fine-textured soils with thoughtful design.

For the past thirteen years Dean Young has worked for the Toronto and Region Conservation Authority. He is currently a Project Manager with the Sustainable Technologies Evaluation Program where his work focuses on evaluating the effectiveness of innovative water management technologies in an Ontario context and developing knowledge transfer tools to overcome barriers to widespread implementation. His most recent work focuses on developing guidance on the design and implementation of Low Impact Development stormwater infrastructure. Dean is also a Director of the Ontario Branch of the Canadian Water Resources Association.

Rain ready: finding solutions to urban flooding

May 8, 12-1pm EDT.

Urban flooding brings misery to millions of homeowners and businesses across the U.S. and, according to research by the Center for Neighborhood Technology (CNT), there may be little correlation between flood risk and proximity to the floodplains. CNT has been researching the cost and prevalence of urban flooding for the last four years while working with residents, communities and government agencies to help design solutions. These RainReady solutions include a RainReady Home upgrade service complete with a property assessment, construction oversight and upfront financing; a RainReady Community service for municipalities to help them plan upgrades in the neighborhood; and a real-time early warning flood alert system. Grassroots community organizing is a critical element of these services - helping residents and businesses be aware of their risks and adopt RainReady solutions.

Harriet Festing is director of the Center for Neighborhood Technology's Water Program, and heads up their work on urban flooding and RainReadySM. Her background stretches from milking cows in rural England, to placemaking advocacy in New York (Project for Public Spaces) and London (Prince's Foundation). Before joining the Center for Neighborhood Technology (CNT) in 2012, she worked in UK Government advising the then–Secretary of State for Energy and Climate Change, Ed Miliband, on public attitudes to energy and climate change policy. Festing is a strong believer in the power of — and need for — citizens to shape their future through community organizing. She is lead author of The Prevalence and Cost of Urban Flooding and RainReady Nation: Protecting American Homes and Businesses in a Changing Climate.

His broad area of expertise includes water resources engineering, stormwater management, low-impact development (LID) design, and porous pavements. He has additional expertise in hydrology and hydraulics evaluations, climate impacts on floodplain and drainage infrastructure, stream restoration and enhancement alternatives, dam removal assessments, groundwater investigations, nutrient and total maximum daily load (TMDL) studies.

Rob has led the technical analysis of several studies examining land use and climate change impacts upon municipal flooding. Specifically he has studied role of Green Infrastructure as a municipal adaptation measure for a climate adaptation planning effort in Exeter, NH, its impact on the 100-year floodplain for communities in the Lamprey River Watershed, and it’s role as a damage and cost avoidance measure in Newmarket, New Hampshire. He has participated as the lead or project team member in many significant green infrastructure projects. Among them was an award-winning downtown street redesign for Portsmouth, New Hampshire, that employed a combined sewer separation, the use of numerous tree filters, a large subsurface chamber system in series with an underground sand filter and other forms of advanced stormwater management. Rob also was a member of the award-winning Long Creek Watershed Management Team that is implementing a comprehensive restoration plan for an impaired urban stream in southern Maine.
