This document – the Low Impact Development Stormwater Management Planning
+
and Design Guide – has been developed by Credit Valley Conservation (CVC) and
+
Toronto and Region Conservation Authority (TRCA) as a tool to help developers,
+
consultants, municipalities and landowners understand and implement sustainable
+
stormwater planning and practices in the CVC and TRCA watersheds. The use of
+
sustainable stormwater planning and practices will help ensure the continued health
+
of the streams, rivers, lakes, fisheries and terrestrial habitats in our watersheds.

== Getting started ==

The guide is intended to provide engineers, ecologists and planners with up-to-date

+
information and direction on landscape-based stormwater management planning and

+
low impact development stormwater management practices such as rainwater

The information contained in the guide will help practitioners adopt landscape-based
+
stormwater management approaches, and will help select, design, construct and
+
monitor more sustainable stormwater management practices.
+
+
This manual is not a stand-alone document. It is intended to augment the Ontario
+
Ministry of the Environment’s 2003 Stormwater Management Planning and Design
+
Manual, which provides design criteria for “conventional” end-of-pipe stormwater
+
management practices such as wet ponds and constructed wetlands. It is also a
+
companion document to other stormwater related guidance documents prepared by
+
CVC and TRCA. Amongst others, these include:
+
+
