Counties. The watershed is bounded by Libertyville on the north and Willow Springs on the south. The watershed has a total population of approximately one million. Exhibit i defines the limits of the watershed and shows the location of major features of the Floodwater Management Plan. Floodwater damage is a principal problem in the watershed with major damage areas located in Cook and DuPage Counties. Approximately 22,000 acres are subject to flooding. Projected average annual floodwater damages to existing development is $5,364,000. The 100 year frequency flood causes extensive damage to 4,700 residential properties, personal property and 320 I� businesses. In addition, flooding closes roads, isolating many areas and 1 interrupting transportation on major highways. Exhibit Z. shows the limits • of the flooding problems with and without the proposed project between North Avenue and Roosevelt Road in Elmhurst and Villa Park. Damage is increasing I� due to urbanization and flood plain encroachment. Erosion on areas being converted from agricultural, forest and idle land uses to urban type developments produces sediment which adversely affects water quality, clogs storm sewers, stream channels and deposits in downstream navigation channels. Erosion on 20,000 acres of agricultural and idle land also produces similar sedimentation and water quality problems. There is a critical shortage.of water-based recreation within the water- shed, and present resources are not adequate to meet recreation and open space needs. These needs will continue to increase as population and development increase in the area. Lower Salt•Creek is one of the major flood damage areas within the watershed. Some 953 homes and 84 business and public buildings are located . . Alk de mai, I Alik ' 1 Ni A on the Salt Creek flood plain affecting Elmhurst, Wood Dale, Addison, Villa Park, Oak Brook and DuPage County. Total average annual flood damages are U $1.2 million which is 20 percent of the total Des Plaines watershed damages. i ij Floodwater management problems have long been recognized in the Chicago area, but until recently there had been no unified effort 'imed at their solution. Communities were seldom able to cooperate to solve mutual flood- water problems; and in many cases, one community's solution adversely affected i downstream areas, Planning at various governmental levels seldom adequately !! recognized natural hazards such as flooding and soil limitations. _ Unified planning came about when the Chicago Metropolitan Area River Basin Study was organized. This study was stimulated by the success of the planning effort for the PL-566 Upper Salt Creek Watershed Project in suburban Cook.County.` Development of this plan proved to the local agencies, the 411 MSDGC, the Soil Conservation Service (SCS) and local residents that flood- :.. .- water management plans could be developed for complex urban areas, In 1971 the MSDGC and the SCS entered into a cooperative agreement under the authority of Section 6.of Public Law 566. The $2,8 million cost of the 5wyear effort was shared between MSDGC and BCS. The metropolitan area outside of the Upper Salt Creek watershed was divided into five watersheds: Des Plaines River I (including Lower Salt Creek), Little Calumet River, North Branch Chicago River, I' Poplar Creek and Calumet-Sag Channel, Each was to be planned to the same intensity as the Upper Salt Creek Project, . Developing the Des Plaines Watershed Plan required approximately five years, Federal planning procedures were used to assure project compatability.. Early studies included preparation of an Environmental Resource Inventory . containing detailed information on water quality, land use, stream and flood 1 plain biota, natural areas, water bodies, wetlands, unique geologic sites, lo I ' t ggq , • , p :. open space and projections of future conditions, Additional studies included hydraulic and hydrologic analyses to determine flood profiles and detailed mapping (1w = 400' , Contour Interval = 2 ft.) ofi15 miles of flood plains. Detailed surveys for approximately 5,000 flood plain buildings were conducted. Damages were determined on the basis of interviews, published data and studies of real property values. Through extensive use of SCS computer programs, the flood profile information was used to determine average annual floodwater ii damage by stream reaches. Public involvement and interagency cooperation has been the key to successful plan development, The Des Plaines Steering Committee is composed of interested citizens, municipal leaders, environmental group leaders and planning commission representatives. DuPage County participants included the DuPage County Forest Preserve District, Regional Planning Commission, Department of Public Works and County Board; City of Elmhurst, Park District and . Environmental Commission; City of Wood Dale and Environmental Commission; Bloomingdale, Oak Brook, Roselle,Salt Creek Drainage District; Medinah Park District, Country Club and Homeowners Association:; Decision making and leader- ship for plan development are,the functions of the.comramittee. The Des Plaines plan reflects the alternatives chosen by the committee to satisfy its water resource management objectives. Decisions concerning plan elements are made in public meetings. The plan is an instrument of the concerned residents with broad public support, not a plan imposed from above by a: select group not fully aware of public needs. The Des Plaines Plan also reflects a good record of interagency cooperation. The Soil Conservation Service (SCS) played a major role as principal developer of technical information. The Illinois Division of Water Resources now effectively uses flood profiles developed• by SCS in its regulation program. • • • w w Both DWR and MSDCC now support final planning and implementation efforts. 4 Illinois Division of Highways along with county highway departments now use a unified data for road design. ' Soil and Water Conservation Districts it are cooperating in erosion and sediment control, • Flood control measures in the Des Plaines Plan include eleven reservoirs (one multiple-purpose with recreation), 5.8 miles of flood control channel . and diversion, and 0.7 mile of dike. Twenty-eight communities and portions of unincorporated Cook and DuPage Counties will benefit from the Plan's imple- mentation. In the Lower Salt Creek portion of the watershed, three reservoirs and 8.45 mile of channel work are needed for flood control. Structures 4 (Spring S Brook Reservoir) and 5 (Medinah Road- Reservoir) near 'Bloomingdale on p Spring Brook will control floodwaters from that tributary, The. Salt Creek Channel will reduce flood damage near North Avenue. Structure 15 (Elmhurst Lake) will store 3,900 acre feet of floodwater to protect downstream areas where much of the Salt Creek damage occurs. Acquisition of land rights is proceeding for the Spring Brook and Medinah Road Reservoirs and the Salt Creek Channel through the DuPage County Forest Preserve District and City of Elmhurst. Elmhurst Lake,shownon Exhibits 3 and 4, is a key element for both Lower Salt Creek and the entire Lower Des Plaines Tributaries Watershed Plan. Its. location immediately upstream from a major damage area is fortunate, There is sufficient storage to provide a 100-year level of protection downstream and also to store earth materials excavated from six of the ten other planned reservoirs. The materials will be hauled by rail to the quarry. This will allow the quarry to be partially filled and shaped into a useable and highly desirable recreation facility including a 9,8 acre permanent :lake. Flood damage along Lower Salt Creek will be reduced 75 percent providng net average annual benefits of $870,000. Activities at the development will include Fishing, hiking, winter sports, picnicking and nature study. Both the Elmhurst Park District and the City of Elmhurst have. been instrumental in developing the recreational plan. Yearly attendance is estimated to be 354,000 providing water-based recreation in an area deficient in this type of recreation. Remaining to be accomplished in the Lower .Des Plaines Tributaries Water- shed Plan is the local sponsorship agreement and :preparation of a final plan for presentation to Congressional Committees. It is estimated that the local sponsorship agreement and final plan preparation will be completed within the next year and Congressional Committees .will begin discussing plan funding in the fall of 1979. . Installation cost of the plan is estimated at $85 million. Of this cost approximately $60 million (engineering and construction cost) would be funded by the Federal Government; -the remaining $25 million would be a local (non- federal) cost.

Two of those sites,-Spring Brook • Reservoir and Medinah Road Reservoir are presently being-acquired by the DuPage County Forest Preserve Distritt,and do not appear to be a problem. Elmhurst Quarry is not being acquired at present and with an estimated acquistion cost of $9 million, it poses a major problem to the implementation of the plan. The Division of Water Resources has given acquisition of the quarry high - priority. However, to acquire the reservoir $9 million would be needed in one year's budget. In FY 79, the Division was given an appropriation of $11 million for capital projects; however, we were limited by the Bureau of the Budget to a cash flow of $5.7 million. The consequence of the FY 79 cash flow • I limit will be a $6.4 million reappropriation to complete on-going construction' projects. Elmhurst quarry will require both an appropriation -and an allowable l . 1 IIIIIIIIIIN * i i• • • . DIP.,,,, : :siAli It iIlti i I it ' 0 3 a e • . . • ''1411111Fel: . • ' .
