August 2016 brought record floods to the Baton Rouge Capital
Region, equaling and surpassing the historic 1983 flood which many pointed to as a worst-case flooding scenario. After
decades of continued land development of the watersheds in this region, fresh, often
contentious discussion around the impacts have been flowing in the public
discourse. With the fork in the road these concerns present to evolving public
policy and expectations upon private development patterns, we've invited Bob Jacobsen,
engineering consultant on flood hydrology, flood risk, & floodplain
management, to illuminate the factors that contribute to flooding in the
region.
Jacobsen will address the July 20th meeting of the Baton
Rouge Group of the Sierra Club about how storm water runoff has been
impacted by: 1) rapid and pervasive development; 2) man-made modifications to
channels (dredging, straightening, lining, etc.) and to floodplains
(road/railroad embankments); 3) subsidence; and 4) anthropogenic climate change
(perhaps the greatest impact). He will also discuss the misconceptions of flood
zones and will suggest steps that need to be taken to prevent or reduce
flooding and its impact on lives and property.
