Airline Highway
(Highway 61) Hurricane Evacuation Route survey results
were presented to the St. Charles Parish Council and Parish
Government on November 3, 2003 -- The St. Charles project
is an National Ocean Service collaborative effort of the
National Geodetic Survey
(NGS), the Center
for Operational and Oceanographic Products and Services
(CO-OPS), the Coastal Services Center and
the Louisiana Spatial
Reference Center (LSRC) at Louisiana State University.
The effort is focused on the study of elevations and tide
and water levels in the Parish. St. Charles Parish is an
actively growing region in southern Louisiana and a major
evacuation corridor for metropolitan New Orleans. As part
of NOAA's Height Modernization Program, the study is part
of an overall effort to look at the elevations of critical
evacuation routes in the state and develop specifications
and procedures for future surveys.
Background:
As part of the "St. Charles
Parish Water Level Monitoring System", CO-OPS
recently established two new real-time National Water Level
Observation Network (NWLON) stations at Bayou Gauche which
is connected to Lake Salvador and at the Labranche Wetlands
area of the southern shore of Lake Pontchartrain. NGS
conducted a two-week GPS survey to provide up-to-date, accurate
heights on a ten-mile portion of Highway 61 (Airline Highway)
and on two new NWLON stations in order to utilize the new
real-time water level information to predict flooding of
the highway during the hurricane season. By surveying the
floodprone portion of Highway 61 near the NWLON stations,
the water level data from these stations will enable the
Parish and emergency managers to accurately monitor, predict,
and plan for the potential flooding of this heavily traveled
route. Contact Tim Osborn.
