impact/compensation assessment method (icat) application for utility corridors
TRANSCRIPT
Impact/Compensation Assessment Method (ICAT)
Application for Utility Corridors
What is ICAT
Modification of the Charleston Method. • Factor definitions revised to reflect South Louisiana
conditions and reflect the watershed approach to compensation brought about by RGL 02-2.
• Some Charleston factors removed and others split. • Overall weightings remain the same. • Weighting of factors changed depending upon
perceived importance by the ICAT work group.• Calculations unaltered (except for cumulative effect)
Why Are We Developing A New Assessment Method
Other methods produce inconsistent and unpredictable results among users
Data collection requiring some degree of expertise
Benefits Expected From ICAT
Has repeatable results among interdisciplinary project managers having variable regulatory experience
Provides a quick and easy assessment methodology
Requires minimal amount of field data collection Uses a single set of worksheets applicable to all
habitats.
An Example Pipeline ProjectApplication # MVN-2006-qxyz
Project Specifics
Impacting high quality, relatively undisturbed forested ecosystem.
30 acres in permanently cleared right-of-way. 15 acres in temporary work areas to be
restored upon completion of the work. Compensation to be provided offsite, within
the basin of impact at either a bank or site specific.

Summary Table
Site Specific Mitigation Project
100-acre site currently in sugar cane. The agricultural area no longer exhibits wetland vegetation and hydric conditions but soils are hydric by definition on all but 5 acres.
Propose to effectively restore hydric conditions to hydric soils and plant the site with hardwood species common to the area.
Perpetual conservation easement to be held by a recognized private land trust.
