CHAPTER 6
DISTRIBUTED MICRO-SCALE SYSTEMS
6-1
INTRODUCTION. In addition to land surface strategies, LID practices include
incorporating small landscaped features and manufactured devices into a site. The
management of runoff as it is generated reduces the need for management further
downstream. Small distributed systems can perform several important runoff
management functions:
Increase rates of infiltration
Slow down runoff, reducing flow rates from the site and increasing
time for infiltration
Add retention (the amount of water stored at the surface for the
duration of the storm event)
Add detention, which causes water to be restrained temporarily
before it moves further downstream
Improve water quality by filtering pollutants through media

REPRESENTATIVE LID PRACTICES. LID uses design components (IMPs)
that can be selected and customized for specific stormwater management objectives.
The selective use and customization of these components will involve a variety of
standards and specifications for construction and maintenance. Described below is a
collection of LID practices and their design, construction and maintenance
characteristics.
Distributed micro-scale systems can include, but are not limited to:
Soil amendments
Bioretention
Dry Wells
Filter Strips
Vegetated Buffers
Grassed Swales
Infiltration Trenches
Inlet Pollution Removal Devices
Rain Barrels and Cisterns
