Low Impact Development (LID) Operations and Maintenance (O&M)
This guidance was developed by Herrera Environmental Consultants (Herrera) and the Washington Stormwater Center under a contract with the Washington State Department of Ecology. This document provides guidance on procedures, equipment and materials, skills, and staffing for LID facility maintenance as well as administrative tools and guidance for implementing LID O&M programs.
Note: In the 2012 Stormwater Management Manual for Western Washington, Volume V, Section 4.6, Ecology refers to grant funding to develop detailed maintenance standards for Bioretention Facilities and Permeable Pavement. This guidance document was created as a result of that grant funding. Ecology recommends that Western Washington Municipal Stormwater Permittees use this LID O&M Guidance Document when adopting maintenance standards for their LID BMPs/facilities.
In June 2013, eight trainings were held throughout western Washington on the Western Washington LID O&M Guidance Document.
