waves crash against the concrete sea wall hugging the shoreline along chicago\u2019s calumet park. sections of the gray boundary between land and lake are crumbling against the constant pressure of the elements.<\/p>\n\n\n\n
with over 25 miles of glistening blue water, chicago\u2019s lakeshore, composed of lake michigan beaches, faces a significant threat. erosion is the shrinking of a shoreline that is slowly worn away by waves, wind, currents and other natural factors, and it is affecting the city\u2019s shoreline at an exacerbated rate due to climate change. <\/p>\n\n\n\n
chicago beaches are narrowing at a rate of nearly 100 ft. per year<\/a> along parts of the coastline, meaning less space for recreation and the loss of habitats for shorebirds and other beach animals.<\/p>\n\n\n\n \u201cin a warming climate, there’s more intense precipitation events, which also tend to facilitate higher rates of erosion,\u201d max berkelhammer, a climate and atmospheric scientist and professor at university of illinois at chicago, said. \u201cthe primary cause is coastal management. like building right along coastlines and not maintaining basically wetlands or or natural shore ecosystems that absorb the action of the lake. so i think it’s primarily a human or urban development issue.\u201d<\/p>\n\n\n\n berkehammer said the primary action in question is the rising lake levels exposing more of the sand to water, wind and the increase in runoff \u2014 when it rains faster than the sand or soil can absorb the water and it runs off a surface, increasing the rate of erosion.<\/p>\n\n\n\n erosion causes damage<\/a> to infrastructure (roads, buildings and parking lots) and natural habitats. it can also threaten public health by increasing the risk of algal blooms<\/a>, quick growing areas of algae that can produce harmful toxins. <\/p>\n\n\n\n edgewater environmental coalition (eec) \u2014 a nonprofit organization focused on action, advocacy and education for environmental stewardship \u2014 has a shoreline protection program<\/a> aimed at restoring the natural ecosystems of the lakeshore using nature-based solutions. the organization has used successful strategies of green infrastructure<\/a> like building dunes, planting native plants and removing invasive ones to mitigate erosion. eec, in conjunction with the loyola university student environmentalist alliance, has planted 300 native grasses and 1,500 marram grass stolons that act as anchors that strengthen dunes across the shore.<\/p>\n\n\n natural solutions can often be more cost effective, visually in tune with the natural landscape and equally as durable as traditional gray infrastructure<\/a> like the concrete ground and walls that make up most of the chicago shoreline, according to eec advisory board member john laswick. he said the main goal of the organization is to reestablish dunes, which are nature\u2019s original protection system.<\/p>\n\n\n\n \u201cwhat we do is go out every last sunday of the month in the summertime and pull out invasive plants, pick up trash, plant new grasses to extend the dune plantings because if you don’t have the sand anchored with grasses and trees, then it’s just gonna blow away or wash away,\u201d laswick said.<\/p>\n\n\n\n while the organization focuses on dunes and native plants, they also promote other natural resources to combat erosion.<\/p>\n\n\n\n natural solutions to erosion<\/strong><\/p>\n\n\n\n friends of the parks (fotp), which provided the seed grant that enables eec\u2019s stewardship services along the shore, is a nonprofit organization focused on protecting chicago\u2019s lakefront and ensuring an equitable, ecological park system. they have enacted policy changes \u2014 such as partnering with the state and chicago park district to implement the illinois clean harbors<\/a> program \u2014 and educate local residents on park stewardship. <\/p>\n\n\n\n gin kilgore, interim executive director of fotp, is a former resident of hyde park, a south side neighborhood a few miles from the lakeshore. she says she grew up observing the power of lake michigan to batter the shoreline during big storms, which she notes are more frequent and intense in recent years due to climate change. during long runs along the lakefront she has seen the limitations of \u201cgray infrastructure\u201d to protect against erosion, such as crumbling sidewalks in front of the calumet beach fieldhouse.<\/p>\n\n\n\n
