Jeff Dennis

Biologist Maine DEP’s Division of Environmental Assessment

Mr. Dennis is a biologist in the Maine DEP’s Division of Environmental Assessment where he heads the Division’s Watershed Management Unit. He has worked since the early 1970s on lake and stream assessment, restoration and protection. Over most of that period, he has been a strong proponent of stormwater BMPs that rely, either intentionally or incidentally, on infiltration. In the past two decades much of his time has been spent on the restoration of healthy biological communities in impaired urban streams, with a recent focus on avoidance of toxic chloride contamination in stream base flow.

As national manager of stormwater solutions for the ACF-CWT Alliance, Mr. Gorneau is responsible for offering innovative green infrastructure/low impact stormwater solutions that enable new applications and raise the bar on performance, cost effectiveness and verification. Mr. Gorneau previously served as regional vice president for FABCO Industries where he was responsible for engineering design, specification and installation of manufactured stormwater management systems. He earned a BS degree in Biological Systems Engineering and an MS degree in Agricultural and Biological Systems Engineering from the University of Nebraska-Lincoln which provided the necessary knowledge for him to launch his career into the technical sales and specified engineered products industry. He spent the subsequent time since graduation gaining experience and expanding his knowledge of the industry on a wide variety of civil and environmental engineering design projects for private and public sector clients. Mr. Gorneau is a registered professional engineer in Maine and New Hampshire, and he is a Maine certified stormwater inspector. He has been a member of the American Society of Civil Engineers (ASCE) since 1999, serving as section president in 2014.

Chip Haskell, PE

Project Manager at CES, Inc.

Mr. Haskell received his B.S. degree in Civil Engineering from the University of Maine in 2008. Since then, he has worked as an engineer on a variety of projects including road and site design and layout, stormwater treatment designs, storm drain and sanitary sewer systems, permitting, and pre-and post-hydrology studies. In 2013 Mr. Haskell became a licensed professional engineer in the State of Maine. His stormwater treatment projects have included design and permitting for underdrained soil filters, wetponds, gravel wetlands, bio-retention cells, rain gardens, porous pavement and concrete and infiltration basins, as well as proprietary systems. As a consulting engineer his goal is to provide sensible solutions that balance the requirements of the regulatory authorities, with the needs of the client considering suitability on the site, budget, and long term maintenance obligations.

John Kuchinski, PE

Senior Project Engineer at CES, Inc.

Mr. Kuchinski has a bachelor of science degree In Civil Engineering from the University of Massachusetts, Dartmouth, and is licensed in Maine, New Hampshire and Massachusetts as a professional engineer. He has over 30 years’ experience in the design of large-scale commercial, industrial, and residential land development projects. Mr. Kuchinski’s experience includes the layout of roads, parking lots, site circulation and pedestrian ways in an integrated design. He has worked with site design and the permitting for site development on projects including grading, stormwater drainage, spill control, utilities, and erosion control.

Johanna Szillery

Senior Project Scientist at CES, Inc.

Ms. Szillery has 20 years of experience in the natural resource and regulatory permitting field, which includes positions in academic research, Federal government, and as an environmental consultant. She is a wetland scientist and a Maine certified soil scientist (ME CSS 494). Ms. Szillery has a master’s degree in Plant, Soil, and Environmental Science from the University of Maine, and completed research on the watershed-scale of climate change and acid rain on biogeochemistry in eastern Maine.
