Use LID everywhere.
LID can work on redevelopment, as well as new devel-
opment sites. In fact, LID can be used on sites that might not traditionally consider
LID techniques, such as in combined sewer systems, along transportation corri-
dors, and on brownfield sites. Broad application of LID techniques improves the
likelihood that the desired outcome of water resource protection and restoration
will be achieved.
Make maintenance a priority.
The best LID designs lose value without
commitment to maintenance. An important component of selecting a LID technique
is understanding the maintenance needs and institutionalizing a maintenance
program. Selection of optimal LID BMPs should be coordinated with both the
nature of the proposed land use/building program and the owners/operators of
the proposed use for implementation of future maintenance activities.
Benefits of implementing LID
Implementing LID offers numerous benefits to communities, developers, and the
public that extend well beyond water quality protection. Here are some examples:
Communities, agencies, and the public
• Reduces municipal infrastructure and utility maintenance costs (e.g., streets,
curbs, gutters, storm sewers).
• Increases energy and cost savings for heating, cooling, and irrigation.
• Reduces flooding and streambank erosion.
• Replenishes groundwater drinking supply.
• Assists in meeting regulatory obligations.
• Serves multiple purposes (e.g., traffic calming, greenways).
• Brings neighborhoods together in maintaining LID.
• Increases recreational opportunities.
• Provides environmental education opportunities.
• Improves quality of life for residents.
• Protects community character/aesthetics.
• Protects and enhances sensitive habitat.
• Restores/protects fisheries and other aquatic life.
• Reduces salt usage and snow removal on paved surfaces.
Developers
• Reduces land clearing and grading costs.
• Potentially reduces infrastructure costs (e.g., streets, curb, gutters).
• Reduces stormwater management construction costs.
