GENERAL INFORMATION
Low Impact Development Center
The Low Impact Development Center is a non-profit organization working to balance growth and environmental integrity. This web page offers information about the benefits of bioretention practices.
Stormwater Manager's Resource Center
On the navigation bar on the left hand side of the page, select "Fact Sheets" then "Stormwater Mgt.". This section of the web site offers fact sheets on a variety of topics related to bioswale functions including grassed channels, bioretention, and filter strips. Most of the fact sheets provide detailed (albeit sometimes conflicting) information on applicability, siting and design considerations, maintenance issues, costs, and treatment considerations.
Design of Vegetative Filtering Systems – Open Channels and Filter Strips.
Online presentation with notes developed by the Center for Watershed Protection and housed on the Stormwater Manager's Resource Center web site. As the introduction to the presentation states: "This slide show explores the design principles of four different vegetative filter practices. Each of the four practices incorporate the four major design components of: flow regulation, pretreatment, filtering, and overflow."
Green Streets Case Studies
City of Portland
The City of Portland, Oregon's has developed many "green streets" technologies that utilize the principles of bioretention in a variety of forms including curb cuts, flow-through planters, and infiltration planters. This web page offers downloadable case studies with photos and detailed information on design, installation, costs, and lessons learned.
Bioswales used in transportation systems
Low Impact Development Center
This web page provides three examples of bioswales used along roadways.
De la Fleur Demonstration Site in Elmhurst, IL
Marcus de la Fleur of the Conservation Design Forum has transformed his Elmhurst, IL home into a virtual watershed friendly landscaping demonstration site. Visit the bioswale section of his web site for more information on the bioswale he installed in a shady area of his property including installation strategy, plant list, and photos.
Siskiyou Curb Extension Flow Test
(This link will directly download the pdf document.)
The City of Portland, Oregon conducted this study of their vegetated curb extensions in order to gather performance data that would help them quantify the benefit of these practices, lower their maintenance costs, and improve their overall design and function. (Vegetated curb extensions are shallow vegetated basins located in the street parking lane that are designed to store, infiltrate, and filter street runoff.) This 28-page document provides detailed information on the study and its results. Includes helpful photos, graphs, and data tables.
