On-Call Wetlands and Associated Environmental Services

CHA was awarded the On-Call Wetlands contract in 2008 and has since continued to provide a full range of environmental services to INDOT’s Ecology and Waterway Permitting Office. The initial contract was a two-year, $1 million term with an option for renewal for another two years. The contract has resulted in over 110 assignments totaling nearly $4 million. CHA manages over 310 acres of wetland mitigation and 56,000 feet of stream mitigation, including monitoring, maintenance, and mitigation site development.

We have provided reasonable, cost-effective, and innovative solutions on a variety of projects. For instance, we have experienced a high rate of success on wetland mitigation development in an industry that has a poor track record. We recently implemented the use of GPS-enabled tablets on this contract and have increased our efficiency with data collection, data management, and map production to complete more projects within schedule and budget.
