Watershed Functions as the Basis for Selecting Low Impact Strategies Case Study: The Tryon Creek Headwaters Development

摘要

The Headwaters Development at Upper Tryon Creek Watershed transformed a derelict site, piped creek, brownfield, degraded wetland, and poor transit into a sustainable development that "gives back" to its neighborhood and watershed. The 2005 Fanno/Tryon Creek Watershed Plan calls for approaches that help return natural elements to the built environment. The Tryon Headwaters Project achieves watershed functions and economic development with creek and wetland restoration, restored habitat, improved creek hydrology and water quality, reduced urban heat island and energy consumption, increased property values, new market rate and affordable housing, property tax revenues, and improved transit for pedestrians, cars and bikes. The project design focused on the application of vegetative stormwater management strategies such as ecoroofs, stormwater planters, and raingardens to accomplish comprehensive stormwater management and other benefits. This project was a private/public partnership and included significant redevelopment and retrofitting on private property and public right-of-way. This presentation will cover planning, design, construction, monitoring and O&M of this project in the context of an urban watershed.
