As consultants to federal, state, and local government, our environmental engineers and scientists marry the principles of engineering, biology, hydrogeology, and earth sciences to develop environmentally sensitive project designs.

We have long considered it important to not only understand, but also respect the local, state, and federal environmental regulations that govern this work. 

How can we help?

We understand that a design is only good if it can be permitted and built. Therefore, embedded within our multi-disciplinary team is extensive expertise in environmental permitting, supporting our project teams throughout SLR to develop designs that improve the management of water resources and preserve our natural environment. 

Supported by our thorough knowledge of surface water management, our work seeks to integrate water and nature through our understanding of art and science, within the communities where we live, work, and play.

Our team

  • Peter Dekker Hydrological Engineer
    Peter Dekker

    Peter has over 10 years’ experience working on mining and urban development projects. He has extensive knowledge of hydrologic and hydraulic modelling including event-based, continuous, and stochastic hydrologic simulation and un-steady, two-dimensional, and dam breach hydraulic modeling. He has experience in the design of surface water management infrastructure including ponds, infiltration basins, drainage ditches, sewers, culverts, and spillways. He has a thorough understanding of urban storm water management solutions to address water quantity/balance, quality, and peak flow concerns.

  • Luis Vasquez Senior Hydrotechnical Engineer
    Luis Vasquez

    Luis is a senior Civil Engineer and environmental consultant specialized in water resources with near 20 years of experience in the areas of hydraulics, hydrology and stormwater management, mostly focused on mining projects for global mining clients. His experience includes hydrological and hydraulic numerical modelling, site wide water balances, planning and design of water management systems, hydraulic design of conveyance structures and water management ponds, dam break analysis, evaluation of environmental impacts on hydrology, and development of mine closure plans.

  • Jeanine Gouin Director of Environmental Management
    Jeanine Gouin

    Jeanine is the Environmental Compliance and Permitting Services Lead and directs the Water Resources Engineering team. She brings over 30 years of experience, and has an extensive background in stream restoration, flood mitigation, watershed analysis, environmental regulations, and impact analysis.

  • Andrew Greene Principal Water Resource Engineer
    Andrew Greene

    From an early age, Andie was drawn to engineering and construction due to the influence of his father and uncle, which translated to summer employment building houses while still in high school. He has a broad range of engineering experience that spans from urban infrastructure design to general civil site development. As Manager of Natural Resources Engineering, Andie leads the design efforts for river restoration, dam removal, and fish passage projects. He also brings a wealth of experience in hydrology, hydraulics, and dam engineering.

Roy Schiff Principal Water Resource Engineer
Roy Schiff

Roy is a Water Resource Scientist and Engineer whose practice focuses on hydrology, hydraulics, sediment transport, floodplains, channel restoration, and transportation resilience. He has been involved in several research projects across Vermont and the region, evaluating the economic impacts of living in floodplains, drafting best engineering practices to reduce future flood risks, improving protocols for habitat assessment, and creating guidelines for channel restoration. Roy was drawn to this industry because of an early and continued love of fishing and being by the river, and in his role he most values the opportunity to help communities in tough situations solve problems.
