MORE ON Phase I Environmental Site Assessments 

These environmental documents are important to ensure the proper due diligence procedures are followed and liability is limited. Every project receiving federal funding requires at least an initial site assessment to determine if there is any known or potential hazardous waste within the proposed project limits, especially projects that include the purchase of new right-of-way, excavation, and/or structure demolition or modification.

Projects where excavation is anticipated to be over five feet in depth would benefit from a Phase I ESA to more accurately determine potential risks from past releases of hazardous materials. A key part of a Phase I ESA is the full review of local, state, and federal environmental records of sites within a defined radius from the project. A Phase I may result in findings of Recognized Environmental Conditions, which may in turn necessitate performing a limited subsurface investigation (Phase II) to obtain more definitive data on contamination that could impact construction.

Some of the Phase I ESAs TGG has successfully completed include:

· Westheimer Road (3.4-mile corridor) Roadway and Sidewalk Reconstruction (City of Houston approved)
· Shepherd Drive (two-mile corridor) and Durham Drive (two-mile corridor) Roadway, Sidewalk, and Utilities Reconstruction (City of Houston approved)
· Southern Brazoria County Maintenance Facility
· City of Conroe Maintenance Facility
· Heise Road Bridge at Rocky Creek, Waller County (rural)
