Low Impact Development Principles
(LID)
Low Impact Development (LID) is a specific development strategy
that addresses stormwater runoff at the source, closely mimicking
the natural, pre-development, hydrologic systems rather than
building infrastructure to handle runoff. LID is required by State
and Federal law for some projects and is encouraged on all
projects. LID principles not only increase the environmental

complement landscaping requirements in the Healdsburg Zoning
and Stormwater Ordinances by promoting the use of low-impact
development features. Many of the design guidelines provided
below indicate LID solutions that are effective on a larger scale.
For single-family development and smaller projects, consider
solutions listed below as well as scaled-down versions. These
guidelines address external features.
