Natural Resources Commission (ANRC) is investigating the Big Watershed (HUC8 #08020304)
to review the current flood risk and identify potential long-term risk
reduction projects that local communities are interested in pursuing. This project is being performed under a
Cooperating Technical Partner (CTP) agreement between the ANRC and the Federal
Emergency Management Agency (FEMA).
Watershed encompasses an area of approximately 947 square miles
and extends across five counties (Lee, Monroe, Phillips, St. Francis, and
Woodruff) in the eastern portion of the State. The major communities in the
watershed include the cities of Brinkley, Helena-West Helena, Lake View,
Marvell, and a small portion of Marianna. Smaller communities include Aubrey,
Fargo, Hunter, LaGrange, Lexa, Moro, Rondo, and Wheatley.
- The Big
Watershed was selected by the ANRC, the State’s CTP with FEMA Region 6, for the
data developed from a Light Detection and Ranging System (LiDAR) is available throughout
the watershed aiding in providing quality data.
losses in the watershed have exceeded $3.2 million from 1978 through 2014, and there
are over 780 policies. These reported values include entire counties which may
or may not be wholly located in the watershed.
County is the only county considered modernized. St. Francis County has a
countywide study; however it is older. Both of these studies were completed
without quality topographic data.
watershed includes the City of Brinkley, which experienced severe flooding in
June 2014. This flooding event was a state-declared disaster.
communities of Helena-West Helena and Phillips County have multiple claims
listed as BCX Claims, which are claims that occur outside the mapped
floodplain. This indicates the need for additional review to determine if the
effective maps are in need of update.
- Four of the
five counties in the watershed have Hazard Mitigation Plans in preparation: Monroe,
Phillips, St. Francis, and Woodruff Counties.
2016, ANRC, as the State CTP, will hold Discovery Meetings in this watershed.
During Discovery, ANRC and FEMA will reach out to local communities to:
information about local flood risk and flood hazards;
- Obtain and
ultimately review current and historic mitigation plans to understand local mitigation
capabilities, hazard risk assessments, and current or future mitigation
- Include multi-disciplinary staff from within each community to
participate and assist in the development of a watershed vision.
