The BMP Handbook is provided below in either one complete download or in individual sections. This handbook evaluates numerous Best Management Practices (BMPs) by explaining where and when to use the BMP, how to install, inspect and maintain the BMP, and if the BMP is used to meet water quality requirements. The handbook also provides design aids that outline how to determine trapping.
BMPs are important in the control of nonpoint pollution including stormwater runoff. These practices are implemented in site specific SWPPPs that identify and promote the most efficient BMPs based on site conditions. Examples of these BMPs include retention ponds, detention and extended detention ponds, vegetative filter strips or buffers, and infiltration BMPs, such as infiltration trenches, medians and swales. All of which are explained in detail in the BMP Handbook.
