PLANNING REPORT NUMBER 44 A COMPREHENSIVE PLAN FOR THE DES PLAINES RIVER WATERSHED Part Two of Three Parts Chapters 11–17 Prepared by the Southeastern Wisconsin Regional Planning Commission P.O. Box 1607 W239 N1812 Rockwood Drive Waukesha, Wisconsin 53187-1607 June 2003 Inside Region $25.00 Outside Region $50.00 Chapter XI RECOMMENDED LAND USE PLAN AND PARK AND OPEN SPACE PLAN FOR THE WATERSHED INTRODUCTION The demographic and economic base and the existing land use pattern of the Des Plaines River watershed were described in Chapter III of this report. Forecasts of probable future population and economic activity levels, together with attendant demands for various land uses within the watershed, were set forth in Chapter IV. Under the alternative future selected for use in the watershed planning effort, the resident population of the watershed would increase from the 1990 level of about 19,700 persons to a year 2010 level of about 33,500 persons, an increase of about 71 percent, over the 20-year period. The number of households within the watershed would increase from the 1990 level of about 6,600 to a year 2010 level of about 11,500, an increase of about 74 percent. Similarly, employment within the watershed would increase from the 1990 level of about 8,200 jobs to a year 2010 level of about 36,700 jobs, an increase of about 348 percent. This growth in population, households, and employment would require the conversion of an additional 8.7 square miles of land within the watershed from rural to urban uses, increasing the amount of land devoted to urban use from about 12.5 square miles in 1990 to about 21.2 square miles in 2010, an increase of about 70 percent. The demand for urban land will have to be satisfied primarily through the conversion of a portion of the remaining agricultural and other open lands of the watershed to urban uses. This conversion, if unplanned or poorly planned and if not properly related to the natural resource base, may be expected to further intensify the existing developmental and environmental problems in portions of the watershed and to expand the scope of such problems within the watershed. It is thus important that new urban development within the watershed be properly related to soil capabilities, to the wetlands and woodlands of the watershed, to the floodlands of the streams and watercourses of the watershed, and to established utility systems. If the intensification of developmental and environmental problems is to be avoided and the problems of flooding and water pollution already existing within the Des Plaines River watershed are to be abated, new urban development within the watershed must assume a pattern which is more carefully adjusted to the ability of the underlying and sustaining natural resource base to support such development. A land use plan must, therefore, constitute a major element of any comprehensive plan for the development of the Des Plaines River watershed. This land use plan element should represent the basic approach to resolution of the growing developmental and environmental problems of the watershed. The land use plan element and any structural water control facility, floodland management, and water quality management plan elements should be mutually supportive in that land use development will determine to a considerable extent the loading on the floodlands and the water control and water quality management facilities, while those features of the watershed will, in turn, influence land use development, particularly in the riverine areas. 391 REGIONAL LAND USE PLAN Because the socioeconomic factors that determine growth in a large urbanizing region, such as Southeastern Wisconsin, operate on an areawide basis, transcending both political and natural watershed boundaries, a land use plan for a watershed within such a region must be set within the framework of an areawide, or regional, land use plan. The watershed land use plan recommended herein is accordingly set within the context of, and reflects the concepts contained in, the adopted regional land use plan for the design year 2010. The regional land use plan seeks to encourage the centralization of urban development to the greatest degree practicable; to encourage new urban development to occur in locations and at densities consistent with the economical provision of public centralized sanitary-sewer, water-supply, and mass transit facilities and services; and to encourage new urban development only in areas which are covered by soils well suited to urban use and which are not subject to such special hazards as flooding. Importantly, the plan seeks to protect and preserve in essentially natural, open uses the primary environmental corridors of the Region. These environmental corridors, while constituting only about 17 percent of the total area of the Region, encompass almost all the best remaining woodlands, wetlands, wildlife habitat areas, surface waters, and associated undeveloped floodlands and shorelands; areas covered by organic soils; areas of rough topography and significant geological formations; sites having scenic, scientific, and cultural value; areas of groundwater recharge and discharge; and the best remaining potential park and related open space sites. Protection and preservation of the primary environmental corridors is considered essential to the protection and wise use of the natural resource base; to the preservation of the cultural heritage and natural beauty of the Region; and to the enrichment of the physical, intellectual, and spiritual development of the resident population. Such protection and preservation is also necessary to avoid the intensification of existing developmental and environmental problems, such as flooding and water pollution, and to avoid the creation of new problems of this type. The topography, soils, and flood hazards in these corridors, moreover, make them poorly suited to intensive urban development of any kind, but well suited to recreational and conservancy uses. While the adopted regional land use plan forms the basis for the watershed land use plan as herein presented, it should be noted that in the preparation of the watershed land use plan, the regional land use plan was refined and detailed to reflect more precisely the flood hazards existing in the riverine areas of the watershed as determined under the watershed planning program; to reflect recent local development decisions regarding major trunk sewer locations; and, to the extent practicable, to reflect

  • (11Gr100), a Historic Native American Short Duration Occupation on the Des Plaines River, Grundy County, Illinois
    The Highlands Site Craig and Vorreyer, 2004 Mundane Place or Sacred Space: Interpreting the Highlands Site (11Gr100), a Historic Native American Short Duration Occupation on the Des Plaines River, Grundy County, Illinois By Joseph Craig and Susan Vorreyer (Environmental Compliance Consultants, Inc.) Archaeological excavations conducted at the Highlands Site near Channahon, Illinois exposed a small, short-duration historic period Native American occupation situated on the upland bluff overlooking the Des Plaines River. Excavated features included four shallow basins, one hearth and a unique semi-circular shallow depression. Historic period artifacts were sparse and included glass seed beads, pieces of scrap copper and lead, and triangular projectile points. Rich amounts of subsistence remains including elk and bison were also recovered from several features. The Highlands site is interpreted as representing a Potawatomi occupation dating to the late 18 th or early 19 th century. Using historical accounts and illustrations of Potawatomi sites and religious customs and activities, the Highlands Site appears to represent a Potawatomi ritual location. Although graves or human skeletal material were not encountered, the analyses of the artifact assemblage, feature morphology and patterning, and interpretation of the faunal assemblage suggests the Highlands site was utilized as a mortuary location. The area surrounding the base of Lake Michigan at the point where the Kankakee and Des Plaines rivers merge with the upper reaches of the Illinois River was the penetration point of the Potawatomi migration into the western Great Lakes region known as the Illinois Country. Beginning in the mid-1600s, the Potawatomi, who inhabited the western Michigan, initiated a series of westward movements to acquire larger hunting territories buttressing their participation in the North American fur trade and also to avoid pressure (and competition) from Iroquois raiders and trappers.

  • Des Plaines River Watershed-Based Plan EXECUTIVE SUMMARY
    Des Plaines River Watershed-Based Plan EXECUTIVE SUMMARY June 2018 EXECUTIVE SUMMARY DES PLAINES RIVER WATERSHED-BASED PLAN WHY A WATERSHED-BASED PLAN? Water is elemental to our lives. Plants and animals, including humans, are largely composed of water, and generally require clean water to survive. Our communities, food systems, energy sources, and countless products that we consume everyday are dependent upon water. Despite this dependence, water is often taken for granted until it affects us directly, usually due to short supply, inundation, or pollution. This watershed-based plan is important because it specifically addresses water-related issues in communities within the Des Plaines River Watershed Planning Area. Clean and abundant water, healthy streams and lakes, and safety from flooding are important to residents and business and therefore play a significant role in the quality of life and economic vitality of our communities. Water does not generally flow according to political boundaries. Consequently, we recognize the watershed as the appropriate scale to address most water resource issues, which often involve multiple political jurisdictions. The Des Plaines River watershed planning area process brought many municipalities, townships, county agencies, wastewater treatment plant operators, and the broader community of homeowner associations, businesses, institutions, non-profit organizations, and residents (watershed Figure Error! No text of specified style in document.-1: What is a stakeholders) together to plan for the management Watershed? and enhancement of water resources in the Watershed diagram courtesy of Arkansas Watershed Advisory planning area.

  • Des Plaines River Watershed Workgroup Factsheet
    Des Plaines River Watershed Workgroup Factsheet Watershed Facts The Des Plaines River watershed covers over 130,000 acres or just over 200 square miles in Lake County Illinois. The Des Plaines River starts just west of Kenosha, Wisconsin and flows south through Racine and Kenosha Counties in Wisconsin, and then through Lake, Cook, and Will Counties in Illinois. The river then joins the Sanitary and Ship Canal in Lockport, flows west through Joliet, before converging with the Kankakee River to form the Illinois River. The Illinois River then flows into the Mississippi River, which flows south to the Gulf of Mexico. In Lake County, there are nine subwatersheds that make up the larger Des Plaines River watershed: North Mill Creek, Mill Creek, Newport Drainage Ditch, Bull Creek, Indian Creek, Buffalo Creek, Aptakisic Creek, Upper Des Plaines mainstem and Lower Des Plaines mainstem. The Des Plaines River watershed includes 33 Lake County municipalities, 12 townships, and two drainage districts. There are eight wastewater treatment plants that discharge approximately 80 million gallons a day of treated wastewater to the Des Plaines River in Lake County. The majority of the mainstem of the river is bordered by forest preserves and open space in Lake County. Water Quality Within Lake County, portions of the Des Plaines River and its tributaries are impaired and are not meeting their designated uses under the federal Clean Water Act. Sections of the Des Plaines or its tributaries are listed as impaired for the following pollutants: o Arsenic o Chloride o Dissolved oxygen o Fecal coliform o Iron o Manganese o Methoxychlor o Mercury o Phosphorus o Polychlorinated biphenyls o Total Suspended Solids The Illinois Environmental Protection Agency (Illinois EPA) is in the process of creating Total Maximum Daily Loads (TMDLs), or “pollution diets”, for several stream segments and lakes, in the Des Plaines River watershed.

  • Des Plaines River
    Section 319 NONPOINT SOURCE PROGRAM SUCCESS STORY Best Management Practices Reduce Siltation fromIllinois Urban Runoff Waterbodies Improved Urban runoff caused siltation of two segments of the Des Plaines River. The Illinois Environmental Protection Agency (EPA) determined that the excess sediment prevented the segments from supporting their designated uses for aquatic life and added them to the 2002 Clean Water Act (CWA) sec- tion 303(d) list of impaired waters. Implementing best management practices (BMPs) using CWA section 319 funds enhanced water quality and helped reduce total suspended solids (TSS) and sedimentation/siltation. In 2008 the Illinois EPA removed both segments from the state’s 2008 CWA section 303(d) list of impaired waters for TSS and sedimentation/siltation. Problem The Des Plaines River (Figure 1) flows 150 miles (241 km) through southern Wisconsin and northern Illinois, eventually meeting the Kankakee River west of Channahon to form the Illinois River, a tributary of the Mississippi River. The slow-moving Des Plaines River flows primarily through Wisconsin marshland before crossing into Illinois, at which point, it flows west through woodland forest preserve districts in Lake County and Cook County (and through the city of Des Plaines), northwest of Chicago. Numerous small, fixed dams cross the river starting in central Lake County and continuing through Cook County. Eventually, the river turns to the southwest and joins with the Sanitary and Ship Canal in Lockport Figure 1. The Des Plaines River flows through before flowing through the city of Joliet. southern Wisconsin and northern Illinois. The Des Plaines River transforms from a prairie creek to a suburban stream, to a large urbanized river, and then finally to a major industrial waterway.
