Eroding shorelines usually develop over long periods of time, and severe situations can be complex, time-consuming, and expensive to remedy. Before jumping right into the installation stage, invest your valuable time and money in a well thought-out project design.
Many resources are available, including this website, to help you become familiar with the array of shoreline treatment alternatives that are available, as well as the advantages, disadvantages, and relative costs of each. However, if you're not sure about all the important engineering aspects of your shoreline zone (e.g., soil quality and structure, subsurface water flows, grading plans, and permits) or if you want advice selecting shoreline plants that will do best in your site conditions, consider consulting with an individual or company that specializes in shoreline and wetland restoration projects.
The U.S. Army Corps of Engineers maintains a listing of engineering and environmental consulting firms that may have expertise relating to wetland and shoreline modifications. At the end of the consulting firms document is a listing of wetland plant and seed nurseries that serve the Chicago metropolitan area.
The Lake County Stormwater Management Commission also maintains a Resource List of environmental professionals and native plant suppliers. Many of these consultants and plant nurseries include an overview of services provided, representative projects, and plant species lists and availability on their websites.
