Urban Stormwater Retrofit Practices

Ellicott City, MD (August 2007)- Over the last four years, the Center for Watershed Protection produced a series of 11 manuals that describe the techniques to restore small urban watersheds. The entire series of manuals were written to organize the enormous amount of information needed to restore small urban watersheds. Manual 3: Urban Stormwater Retrofit Practices has now been released.


Until now, no definitive guidance has been available on the art and science of urban retrofitting. This manual reflects over two decades of Center experience in retrofitting more than 25 urban watersheds across the country.
This manual outlines the basics of retrofits, describes the 13 unique locations where they can be found, and presents rapid methods to find, design and deliver retrofits to meet a wide range of subwatershed objectives. The concepts of retrofitting are illustrated in more than 75 figures, 150 photos, 60 tables and nine appendices.
The manual contains:
* Updated costs for retrofit practices,
* Updated pollutant removal data for stormwater treatment options,
* Design point method to estimate individual retrofit removal rates, and
* Practical tips to support the design, permitting and construction of retrofit projects.
The other resources in the Restoration Manual Series are:
1. An Integrated Framework to Restore Small Urban Watersheds
2. Methods to Develop Restoration Plans for Small Urban Watersheds
3. Urban Stormwater Retrofit Practices (including Appendices)
4. Urban Stream Repair Practices
5. Riparian Management Practices
