Low Impact Development (LID) for Nursery and Landscape Professionals
Stormwater is regulated under the federal Clean Water Act administered in Washington State by the Department of Ecology.
Under Department of Ecology’s direction, cities and counties are required to integrate Low Impact Development (LID) into their local development and re-development regulations when they update them. Western Washington will require the use of LID for new development and redevelopment and Eastern Washington will allow the use of LID. Implementation of regulations will be come between 2015 and 2018 with most cities and counties implementing new regulations by December 2016.
What does this mean for landscapers and nurseries?
Stormwater will increasingly be managed with LID rather than conventional management techniques.
LID strives to mimic pre-developed drainage by using on-site natural features, site design, and runoff distribution. LID strategies include bioretention like rain gardens, permeable pavements, runoff dispersion through natural vegetation, and restoration of soil quality and depth.
! Provide ideas to your local leaders as they develop new policies encouraging or requiring LID. Municipal Research and Services Center of Washington
, provides information on city and county officials in the planning department to make contact with in regard to LID.

Recorded Low Impact Development Webinars
In Spring of 2013 the Department of Ecology funded three free webinars about three prominent features of LID landscapes: plants, raingardens and bioretention, and permeable pavement. The webinars also included information about upcoming regulatory changes that will increase the use of LID, the schedule for regulatory implementation, the opportunities for landscape and nursery professionals, and how to prepare. The webinars included presentation and discussion from experienced landscape, nursery and industry professionals.
Plant Selection and Propagation for Low Impact Development
Webinar presenters discuss techniques for selecting plants, broadening the plant palette and growing native plants appropriate for LID in a nursery setting.

Structure, Maintenance and Opportunities for Rain Gardens and Bioretention Facilities
Ever wonder what the difference is between rain gardens and bioretention facilities? Presenters explain the differences of these two types of LID facilities along with their structure and maintenance requirements, and present experience and insight on preparing your business to install and maintain rain gardens as well as market them.
