News & Event
The Cordova, Illinois cleaning is a unique event with many different groups working together along the Mississippi River.
Holland Engineering Biologist, Larissa Herrera, volunteered for the Cordova Mussel Event in Cordova, Illinois this summer. The event is sponsored by the US Army Corps of Engineers and has been taking place for over 15 years.
The goal is to clean zebra mussels, a damaging invasive, off the native freshwater mussels and assess the population of the federally endangered Higgins Eye Pearlymussel. Zebra mussels attach to any hard substrate to have a strong foothold where they can feed and grow. When densities of zebra mussels get high enough, they can kill the native mussels. Overall, the zebra mussel coverage was spotty throughout the Cordova mussel bed, and the native mussels with zebra mussels attached to them seemed to be doing well. Larissa holds a USFWS permit to survey and handle federally listed mussel species.

Earlier this summer, our Environmental Group presented at a U.S. Department of Agriculture “Working with Wetlands” field day at Vic Rogers Farm in Benton Harbor, Michigan. Attendees included local farmers in Berrien County, various local conservation program representatives, and Michigan Department of Environmental Quality (MDEQ) staff.
We were thrilled to present our ongoing restoration project in Benton Harbor which included adaptive management of a wetland site to meet MDEQ wetland restoration requirements. The management issues presented to the attendees included the creation of turtle and other wildlife habitat structures, invasive species control, and selection of wetland plantings for successful vegetation establishment.

throughout the energy, civil infrastructure, and government sectors, Holland Engineering has added two new team members to the Environmental Group. Each of them brings a diverse set of skills that will greatly benefit our clients.
Senior Project Manager/Consultant
Gary recently joined Holland Engineering after a long career in the Environmental Services Department at Consumers Energy Company, a combined electric and gas utility in Michigan and subsidiary of CMS Energy. His most recent position as Director of Environmental Services in the Land and Water Management area involved the supervision of staff engaged in the permitting and implementation of gas and electric projects and engagement in federal and state policy making.
He served on the policy committees of the Utility Water Act Group and the Utility Solid Waste Activities Group (primarily in the coal ash regulatory area) and served as an advisor to the Electric Power Research Institute (EPRI) on coal ash regulatory and beneficial use matters. In Michigan, Gary served as the utility representative on former Governor Granholm’s Wetland Advisory Council and former MDEQ Director Wyant’s Water Use Advisory Council. He has also served on the MDEQ’s Solid Waste Advisory Committee and MDNR’s Michigan Natural Heritage Committee, Non-game Advisory Committee, and Citizen’s Endangered Species Advisory Committee. He has been a key player in Michigan legislative and rule making initiatives involving wetlands, inland lakes and streams, floodplains, water withdrawal, Clean Water Act compliance, industrial landfill regulation, and the beneficial use of industrial by-products and soils. He has also been a key player in fisheries, wildlife, and forestry aspects of FERC relicensing for 13 hydroelectric projects and the Ludington Pumped Storage Project.
Larissa Herrera recently joined Holland Engineering after working for an environmental consulting firm in Chicago. She has over eight years of experience in natural resource assessment including working in the private, federal, and university sectors. She has a Bachelor’s degree in biology and program in the environment from the University of Michigan and a Master’s in Water Resources Science from the University of Minnesota Duluth. Her areas of expertise include fish, macroinvertebrate, and mussel surveys, anti-degradation analysis, tree surveys, wetland delineations, water quality, and wetland permitting. She is certified in the State of Ohio for mussel surveys including threatened and endangered species. She has a federal permit in progress for federally listed mussel species surveys. Larissa has experience in vegetation management in high-quality natural areas including habitat for threatened and endangered species.

Cursory Review Maps – Typically, an environmental project starts with this set of mapping. Completing a desktop environmental review of the project area, to figure out the types of permits the project will need. Which then starts the discussion of how much a project is going to cost. Wetlands, floodplain, watercourses, and soils, are some of the environmental factors we review before starting a project.
Arc Collector for Field Collection
NEPA Process Figures – An Environmental Assessment (EA) is part of the decision-making processes, that takes into consideration all environmental and socioeconomic effects of proposed actions. The EA analyzes potential environmental impacts of proposed actions and their alternatives for public understanding and examination, by avoiding or minimizing adverse effects of proposed actions, and restore and enhance environmental quality to the extent practicable. Our Environmental and GIS team has evaluated multiple projects in the past year.
Alignment Sheets – Using Lightning, a program created by Blue Sky Development, we were able to produce pipeline alignment sheets in ArcMap for several projects this year. Lightning is ideal for design, construction, as-built and maintenance projects.
