Ascension begins comprehensive Floodplain Master Plan process

Survey Locations Map

Contractors for the East Ascension Consolidated Gravity Drainage District today began surveying channels in East Ascension Parish as an initial step in the development of the parish’s comprehensive floodplain master plan. Survey work involves multi-person crews in the field physically measuring the width and depth of drainage channels and bayous.

“Data collected from the survey work will be used to determine the capacity of the parish’s drainage basins and be utilized to run computer models that will determine projects and assist in alleviating future flooding,” said Parish President Clint Cointment.

Survey work will progress over the next several months. Citizens should expect to see survey crews in the northern areas of the parish initially, with crews expanding their work across East Ascension over time.

Ascension Parish received record flooding from the Amite River and tributaries in August 2016. That flood demonstrated the need for a long-term comprehensive solution for effective floodplain management. The master plan will be used as a management tool to reduce risk of the damaging effects of floods, protect people and property, maintain and enhance natural floodplain values; and manage water and land resources within floodplains.

The master plan ultimately will be developed into a resource to document known flooding problems, provide a database of flooding and drainage issues, and establish overall procedures and measures for addressing flood issues before, during and after major events and provide a tool to evaluate proposed development to ensure it does not result in offsite impacts.

“This floodplain master plan will become a living document for our local communities to use and manage flood hazards identified by the Parish,” said President Cointment. “As part of this project, we will develop a capital improvement plan for planning, design and construction of recommended projects that we can begin implementing soon to reduce flooding impacts Ascension Parish citizens have become all too familiar with in recent years.”

The master plan is being developed by a consultant team led by HNTB Corporation. Should citizens have questions or information related to the master plan, they should contact John Monzon, HNTB Project Manager, at jmonzon@hntb.com or (225) 368-2823.
