Mobile Harbor General Reevaluation Report (GRR)

The US Army Corps of Engineers and the Alabama State Port Authority are conducting a study to determine the feasibility of enlarging the size of the channel leading to and from port facilities located in Mobile Bay.

Background

In 1986, Congress authorized various modifications to Mobile Harbor including deepening and widening the majority of the channel to 55 feet deep and 550 feet wide. Since that time, the majority of the channel was enlarged to 45 feet deep and 400 feet wide.

 

In 2014, the Alabama State Port Authority requested that the Corps of Engineers consider deepening and widening the existing Mobile Harbor Channel to its authorized dimensions.

 

In response to that request, a General Reevaluation Report (GRR) will be prepared that details the feasibility of widening and deepening the channel up to and including the authorized dimensions.

GRR

The elements and process of developing a General Reevaluation Report (GRR) are defined in legislation and in Corps guidance.

 

The purpose of a GRR is to investigate and recommend solution(s) to water resources problems. These studies are cost shared with a non-Federal sponsor.

 

The study will incorporate engineering, economic, real estate and environmental analyses.

 

It is anticipated that the GRR will be a 4 year, $7.8M effort.

 

Along with the GRR, an integrated Supplemental Environmental Impact Statement (SEIS) will be developed. The SEIS will define the current environmental conditions to compare with the environmental effects of any proposed action and its alternatives. The SEIS will identify potential consequences and the mitigation needed to minimize adverse impacts.
