Stormwater Plans in Prince George's County Can Now Go Forward
On Tuesday, July 19, 2011, the Prince George's County Council adopted its long awaited Stormwater Management Ordinance (otherwise known as CB-15-2011)(the "SWM Ordinance"). The SWM Ordinance requires developments to use environmental site design (ESD) to the maximum extent practicable (MEP). Essentially this means the old systems of stormwater management ponds and underground storage systems are no longer preferred and run-off must be handled in a way that is as close as possible to predevelopment conditions. In addition, for redevelopment projects that used to be required to handle 20% of their stormwater, they must now handle 50% up until 2016, then 75% until 2019 and thereafter 100%. Here are a few of the critical dates:
By May 4, 2010: Exemption for projects with Final approval. For projects with only Concept stormwater management approval, they can receive an administrative waiver and then must get final approval by May 4, 2013 and construct the facilities by May 4, 2017.
For all plans approved after May 4, 2010: New projects must provide ESD to the MEP. Redevelopment projects must reduce the impervious area within the limits of disturbance (LOD) by 50%.
For Redevelopment Projects approved after May 4, 2016: Redevelopment projects must reduce the impervious area in the LOD by 75%.
For Redevelopment Projects approved after May 4, 2019: Redevelopment projects must reduce the impervious area within the LOD by 100%.
The SWM Ordinance will require a much different type of site design and will have significant impacts on new and redevelopment projects.
