| 1. | Water Quality Compliance Master Plan for Urban Runoff (April 2009)
This master plan outlines the City’s strategies for compliance with water quality regulations and was adopted by the Board of Public Works in April 2009. LID is one of the proposed strategies to improve the quality of the City’s waters. |

| 2. | Green Infrastructure for Los Angeles: Addressing Urban Runoff and Water Supply through Low Impact Development (April 2009)
Stormwater pollution, water shortages, flood control, climate change, and the availability of natural green space have all become pressing environmental issues for cities around the nation including the City of Los Angeles. This report examines Low Impact Development (LID) for the City of Los Angeles and potential steps for instituting city-wide low impact development programs or projects to address many of these environmental concerns, especially those related to water management.

| 3 . | City of Los Angeles Green Design Standards (in development)
This document will provide the details and standard plans for designing LID applications in streets, alleys, residential properties, and open spaces such as parks. This document is a work in progress: it was started in July 2009 and revisions will be made available on a biweekly basis. Standard plans are pending the final approval of several City departments and may be subject to change.

| 5. | L.A. Rainwater Harvesting Program
A typical Los Angeles home directs about 14,000 gallons of rainwater through its downspouts into the storm drain system every year. While collecting pollutants on the way, this water ultimately gets to Santa Monica Bay and pollutes our beaches. The L.A. Rainwater Harvesting Program is a pilot program that provides free rainwater harvesting installation for 600 property owners in the targeted neighborhoods by Fall of 2009. By capturing the roof rainwater and using it for lawn and garden irrigation, pollution will be reduced and water will be conserved. Ultimately, it is the goal that the pilot program will be expanded throughout the City. |

Stormwater pollution, water shortages, flood control, climate change, and the availability of natural green space have all become pressing environmental issues for cities around the nation including the City of Los Angeles. Many of these environmental concerns can be addressed by Low Impact Development (LID).
LID can be described as the use of practices that encourage site sustainability and smart growth in a manner that respects and preserves the characteristics of the City’s watersheds, drainage paths, water supplies, and natural resources. Or in simpler wording: bringing nature back to our City to help with urban runoff management, water conservation, and improving the quality of the City’s waters. LID reduces the impact from urban development and provides the benefits of:
 |
Replenishing groundwater supplies |
|
Improving the quality of surface water runoff |
|
Stabilizing natural stream characteristics |
|
Preserving natural site characteristics, and |
|
Minimizing downstream impacts. |
There are many ways we can increase groundwater supplies and prevent stormwater from flowing to our storm drains and polluting our rivers and oceans. The key to effective LID is to capture urban runoff and use it on the site for infiltration, irrigation and other beneficial uses before it enters the storm drain system. We can do this in and around our homes, as well as in our streets, alleys, parks and other open spaces throughout the City.
The information provided here contains links to design standards, guidelines suggestions and additional reading about incorporating LID use in Los Angeles. This information is to assist home-owners, developers, planners, engineers, landscape designers, and anyone else that is interested or professionally involved with the development and redevelopment of Los Angeles.
With this information, we hope to encourage everyone to make a difference and embrace LID as a way to improve the quality of life in Los Angeles. LID is a relatively new concept, but is gaining acceptance rapidly throughout the nation. This website will be frequently updated as new information becomes available. For any questions, please feel free to email staff and use the Subject Title "LID Info."
