Maryland Department of the Environment (MDE) has proposed revisions to Chapter 2 of the Stormwater Design Manual (Design Manual), the stormwater management regulations. Changes to Chapters 1, 3, 5, and the appendices will also need to be made. The proposed changes as a whole are designed to simplify the stormwater management design process, remove outdated and conflicting material that is currently in the Design Manual, and combine into one the two chapters (Chapters 3 and 5) that describe stormwater management practices. More information on this process can be found here.
