This includes all Center-published materials related to stormwater management, including BMP design guidance, stormwater program assistance, stormwater retrofitting, and research on stormwater quality and BMP effectiveness.
Runoff Reduction Method Technical Memo (Center for Watershed Protection and Chesapeake Stormwater Network, 2008). This memo uses extensive background research on BMP performance to determine the ability for the BMP to reduce the overall volume of runoff in addition to pollutant removal. The method also incorporates built-in incentives for environmental site design, such as preserving forests and reducing soil disturbance and impervious cover.
Pollutant Trading is an up-and-coming topic in stormwater management, especially in places such as the Chesapeake Bay and other watersheds where TMDLs are driving numerical limits for stormwater discharges. State and local programs are seeking effective ways to trade pollutant loads between nonpoint sources in order to meet overall pollutant load reduction goals at the watershed scale. This paper focuses on trading and offsite compliance options for nutrients, with a focus on the Chesapeake Bay watershed. However, it is relevant to other areas seeking to set up this type of program. The paper is not a “how-to” guide for setting up a program, but introduces important policy and programmatic issues with program development. The paper was co-authored by the Center for Watershed Protection and the Williamsburg Environmental Group.
Deriving Reliable Pollutant Removal Rates for Municipal Street Sweeping and Storm Drain Cleanout Programs in the Chesapeake Bay Basin (N. Law and K. DiBlasi and U. Ghosh, University of Maryland Baltimore County, 2008). This research project report provides information to support pollutant removal efficiencies for street sweeping and storm drain cleanout practices for Phase I and II communities in the Chesapeake Bay watershed. Information and data was gathered for this project through a comprehensive literature review, a basin-wide municipal survey of existing street sweeping and storm drain cleanout practices, and an intensive field monitoring program within two study catchments located in Watershed 263 in Baltimore, MD and additional sites in Baltimore County.
Managing Stormwater in Your Community: A Guide for Building an Effective Post-Construction Program (Center for Watershed Protection, 2008). This guide provides stormwater professionals with practical guidance, insights, and tools to build effective programs. The guide is accompanied by several downloadable "tools." The tools are designed to be used and modified by local stormwater managers to help with program implementation and can be downloaded individually below.
The National Stormwater Quality Database, Version 1.1: A Compilation and Analysis of NPDES Stormwater Monitoring Information (A. Maestre, and R. Pitt, University of Alabama; and Center for Watershed Protection, 2005). This report summarizes the National Stormwater Quality Database v. 1.1 (NSQD), which contains selected water quality information from the monitoring carried out as part of the U.S. EPA's NPDES Phase I stormwater permit applications and subsequent permits, during the period of 1992 to 2002. This database contains about 3,765 events from 360 sites in 65 communities from throughout the U.S.
The Economics of Stormwater BMPs in the Mid-Atlantic Region (W. Brown, T. Schueler, 1997). This report presents cost data (1996-97) for urban stormwater practices, updates cost prediction equations, and assesses the cost-effectiveness of the BMPs most commonly used in the Mid-Atlantic region, including dry ED ponds, wet ponds, wetlands, and sand filters.
Stormwater Management Pond Design Example for Extended Detention Wet Pond (R. Claytor, Jr., 1995). This 73-page stormwater management pond design example sets forth a step-by-step approach for the design of a stormwater management wet extended detention pond in the mid-Atlantic piedmont region of the United States.
Stormwater BMPs in Virginia's James River Basin: An Assessment of Field Conditions & Programs (Center for Watershed Protection, 2009). This report provides findings from a 2008 visual survey of stormwater management BMPs in eight localities and a review of four local stormwater management programs in the James River basin. This report provides results and recommendations regarding proper BMP design, construction, and maintenance methods as well as programmatic features that can affect the types and quality of stormwater BMPs that are installed within a locality. This study was part of the broader Extreme BMP Makeover project, a three-year endeavor to aggressively improve the pollutant reduction achieved by stormwater management practices serving development in the James River watershed.
Stormwater BMP Design Supplement for Cold Climates (D. Caraco, R. Claytor, 1997). Some of the challenges of cold climates, such as freezing temperatures and high runoff during snowmelt events, influence the effectiveness of traditional stormwater designs. This document describes modifications to traditional stormwater designs to make them more effective in these environments.
NPDES Survey: Results of the Stormwater Regulatory Questionnaire. The survey was administered through the Center for Watershed Protection and distributed through the online survey provider “Survey Monkey” using a modified Dillman technique (Dillman 2007). The survey was conducted to measure the priorities and extent of State regulatory action in the implementation of water quality requirements.
These survey results are discussed in the recent publication: Collins, K.A., Lawrence, T.J., Stander,E.K., Jontos,R.J., Kausha, S.S., Newcomer, T.A., Grimm, N.B., Cole Ekberg, M.L. (2010) Opportunities and challenges for managing nitrogen in urban stormwater: A review and synthesis. Ecol. Eng. Vol. 36, Issue 11, pg 1507-1519
National Pollutant Removal Performance Database Technical Brief (Version 3.0) (L. Fraley-McNeal, T. Schueler, R. Winer, 2008). The National Pollutant Removal Performance Database v. 2 was recently updated to include an additional 27 studies published through 2006. The updated database was statistically analyzed to derive the median and quartile removal values for each major group of stormwater BMPs. The data are presented as box and whisker plots for the various pollutants found in stormwater runoff.
National Pollutant Removal Performance Database for Stormwater Treatment Practices, version 2 (R. Winer, 2000). The second edition modifies, clarifies, and expands upon the original National Database of BMP Pollutant Removal Performance. This comprehensive report contains summaries of more than 135 urban pollutant removal monitoring studies. Includes a statistical and graphical comparison of removal rates for six groups of stormwater management practices: ponds, wetlands, open channels, filters, infiltration and on-site devices. In addition, key research gaps in terms of parameters and practices are identified.
Monitoring to Demonstrate Environmental Results: Guidance to Develop Local Stormwater Monitoring Studies Using Six Example Study Designs (N. Law, L. Fraley-McNeal, K. Cappiella, and R. Pitt, University of Alabama, 2008. A joint effort between the Center and the University of Alabama, the manual presents the broad concepts and methods behind setting up special monitoring studies in support of the NPDES stormwater permitting program. The monitoring study designs cover a range of monitoring areas depending on the sophistication of the monitoring program -- from characterizing the quality of stormwater to developing a paired watershed study that breaks down the larger issue of protecting water quality into manageable components that can be addressed on a priority basis. Each study design covers the essential elements of establishing a monitoring program to include scoping, budgeting, funding and staffing needs as well as equipment and sampling requirements. Special issues associated with each monitoring study design are also covered for those unforseen but inevitable problems.

Provides detailed schematics and design criteria for stormwater management, along with alternative design configurations, sizing guidance, and easy to follow step-by-step design examples. Describes the most applicable development conditions for each filter, and outlines key feasibility factors. Illustrated with over 50 figures and 60 tables.
