Environmental Services  

With NPDES (National Pollutant Discharge Elimination System) Phase I & II storm water regulations increasingly affecting land development and watershed management in urban areas, doing the right thing at the right time can mean the difference between compliance and noncompliance that can potentially whipsaw program results and expenses. Too often, developers and municipalities in coping with tightening budgets are faced with managing a diverse array of specialty contractors to try to manage environmental programs. We offer accessibility to experienced and capable personnel. From planning to execution, we have the resources and equipment to respond to any environmental challenge.

Stormwater Control

Storm water control has become increasingly challenging as rain-events are growing heavier and more intense with climate change. The objective is to move this water in a way that minimizes sedimentation and maintains an adequate clarity that allows release o site with the minimum costs. In the past, too many people considered the application of basic silt fence around construction site boundaries as creating a barrier like a “baby pool” and simply having the water flow into a holding area. In today’s regulatory environment, much more sophisticated systems are required.

Silt Fence

Silt fence is one of the basic tools in the ESC toolbox. Too o en silt fence is installed improperly, either where it does little good or in such as way as it has little opportunity to control/redirect storm water flows during a rain event. At Emerald, we work to ensure that any silt fence installation on will work as performed or have the design changed. Using state-of-the-art static slice trenching techniques as well as custom installation on, on average when not mechanically damaged, will last over three years.


Native landscape restoration takes many different forms. In the Midwest, the two major focuses of native restoration typically involve dealing with upland prairies and wetlands. But servicing either one of these two types of native landscapes takes in a myriad of specific ecosystem issues that go well beyond tilling ground and/or spreading a little seed. Too often, bidding packets do not adequately detail these issues and leave a large room of discretion on the contractors part as well as latitude on implementation.
