"The aim of the Urban Forest Research Project was to illustrate the importance of urban trees as a form of ‘green infrastructure’ where they reduce rainwater runoff and rainwater intensity. In addition, trees cause a delay in precipitation reaching the ground," states Dr. Markus Weiler.
“Through our years of research and advocacy on water management issues, we realized that there was something of a disconnect between information and action. Rain Ready seeks to close that gap by making it easier for homeowners, businesses, and government leaders to create Rain Ready plans," said Harriet Festing. The Rain Ready website features videos and how-to factsheets that show rain readiness in action.
"Several presentations dealt with stormwater management in a larger community context. Several of the speakers expressed interest in writing articles on the topic for Stormwater magazine. This initiated the idea that became our Green Infrastructure & Community Design Series. Colorado-based engineer Paul Crabtree coordinated the effort," stated Janice Kasperson.
By combining sensors and cloud computing, a new pilot project in Chicago provides an innovative solution for what can be an everyday urban problem: rainwater. “We would like to know at a high level whether the green stormwater infrastructure is working,” said Brenna Berman. “Is it preventing rainwater from entering the sewer system? Which designs work better in hard rains versus soft rains? Which work better during long storms versus flash floods?”
"Despite some state government opposition, there is a great case for making stormwater resources that hit the ground on the property of local councils. This could incentivise councils to treat, harvest and sell water resources to industries or direct to citizens for non-potable uses," stated Grant Duthie. "If water authorities were required to engage councils, as the owners of stormwater resources, there would likely become far more incentive to co-develop WSUD principles."
Property redevelopment and construction of McMansions were radically altering the residential landscape. This also impacts how, and how much, rainwater runoff reaches creeks. “The District of West Vancouver has undertaken to implement a requirement for site landscaping as part of both new development and the redevelopment of properties throughout the community,” states Jim Bailey.
The report highlights several innovative green infrastructure stormwater projects. "By examining projects over diverse parts of the country, readers will be able to assess trends and techniques that consider various stakeholders in their stormwater projects," wrote Margaret Buranen. "There are a variety of ways to handle rainwater runoff with green infrastructure and many factors to consider when evaluating options."
"The genesis of this approach lies at the point where rainfall strikes an urban environment surface, where it can be captured via rooftop gardens and water tanks under a notion of retaining water as opposed to having it wash away," says John Argue. "Water which is not captured by these practices can potentially be infiltrated into the soil or be channelled through vegetated bio retention systems or rainwater gardens."
"Instead of expanding our infrastructure, we put together a plan to price, value, reuse, recycle, infiltrate, transpire or otherwise manage, every drop of rainwater we could. We started to invent the millions of ways to reduce the amount of rainwater that arrived at our sewer inlets. The goal was to consider rainwater as a commodity and a resource—if it enters a sewer drain it becomes a costly waste product," explained Howard Neukrug.
Over time, the Stormwater Utility provides the City with the capability to foster a watershed stewardship ethic and influence landowner actions on the ground for the common good. “With implementation of our stormwater utility and Rainwater Rewards Program, we have provided a basis to facilitate and grow a change in thinking, so that increased awareness results in action. The program foundation resulted from listening to feedback."
