Weather Update #17

Saturday, August 20, 2016

St. John the Baptist Parish - Emergency Operations Center staff are aggressively monitoring water levels this morning and surveying the Parish for changes. It appears that flooding is receding and the gauges at Hwy 51, Woodland, Foxwood, Reserve, Garyville, Lake Maurepas and Lake Pontchartrain have decreased since yesterday.

All I-10 and I-55 on and off ramps are dry this morning and passable.  Currently, the rear of River Forest is experiencing minor street flooding as well as saturated areas of Reserve near ZA Montz Road and Garyville near Hwy 54/US 61.  The ditches, drainage outlets, canals and fields on the Western side of the Parish remain saturated.  We are monitoring areas that continue to hold water very closely today.  

Residents should continue making preparations for possible backwaterflooding including sandbagging homes, removing vehicles off of low-lying roadways and safeguarding assets. We are in communication with Coastal Protection and Restoration Authority, The Levee District and Governor’s Office of Homeland Security and Emergency Preparedness on the possible breaching of Alligator Bayou Road in Ascension to ensure there are no negative impacts to our Parish and are awaiting confirmation of a final decision.
