Master Stormwater Plan & Flood Reduction Projects
The MSWMP includes a proposed flood reduction project for each location to the optimum protection level and then prioritizes each proposed project by the estimated total costs and benefits.
The areas listed below are locations in the Village where flood reduction projects are being proposed. The Village Board, staff and stormwater consultant are currently in the process of evaluating a stormwater utility user fee to fund the proposed flood reduction projects and complete the necessary maintenance of the Village’s stormwater management system. More information will be provided as it becomes available.

STUDY AREAS
Proposed Improvements
Project Cost: $6,491,370 (2018 Dollars)
Existing Conditions
The intersection connects to a storm sewer system that is below water elevation in the receiving ditch on Oak Spring Road. This causes the storm sewer to be submerged up to 5 feet and unable to drain.
Proposed Improvements
Install a new storm sewer at the intersection of Appley Avenue, 2nd Street, and Oak Spring Road. Construct a new outfall with a water quality structure that will discharge to Lake Minear on the north side of Oak Spring Road.
Project Cost: $792,625 (2018 Dollars)
Existing Conditions
There is a large tributary area from the west along the rear yards and the existing storm sewer system that drains to the existing detention basin has insufficient capacity. In addition, there are no safe overland flow routes established.
Proposed Improvements
Install a new sufficiently sized storm sewer to collect the rear yard drainage and route to the existing detention basin.
Project Cost: $914,745 (2018 Dollars)
Existing Conditions
There is a very large tributary area from the west side of Milwaukee Avenue and the current storm sewer system has insufficient capacity to convey flows. In addition, there are no safe overland flow routes.Proposed Improvements
Install a new main line storm sewer along Glendale Road from Wrightwood Terrace to the Des Plaines River. Remove and replace the existing storm sewers along 4th Avenue west of Copeland Manor Elementary School and on the school property. The new sewer system would then connect into a new storm sewer along 7th Avenue. This new sewer would then connect into the proposed Glendale Road storm sewer and have a parallel outfall to the Des Plaines River.
Project Cost: $6,491,370 (2018 Dollars)Existing Conditions
The existing storm sewer capacity is insufficient. In addition, there are no safe overflow routes on West Ellis and through homes on East Ellis and Sandstone Drive.
Proposed Improvements
Construct new floodwater storage basin (1.5 ac-ft) at the western end of W. Ellis Avenue to drain the existing depressional area. Install a new storm sewer from the proposed storage basin to the new and larger E. Winchester Road storm sewer system extending all the way to new outfall pipe at the north end of Lake Minear. Disconnect the east existing storm sewer system from new west system. Install a new storm sewer along Sandstone Drive and connect into the existing system going north.
Proposed Improvements - Alternate
Construct a new floodwater storage basin (1.5 acre-feet) at the eastern end of W. Ellis Avenue to drain the existing depressional area. Install a new storm sewer from the proposed storage basin to the new and larger E. Ellis Avenue storm sewer system following the alignment of the existing storm sewer. This new sewer alignment will then extend southward along Sandstone Drive and out to Lake Minear through an easement(s) to be obtained from a private property owner(s).
Project Cost: $5,176,560 (2018 Dollars)
Project Cost - Alternate: $4,445,940 (2018 Dollars)
Existing Conditions
There is a large tributary area from the southwest of the Willow Avenue and Harding Avenue intersection. The resulting overland flow drains through rear yards from the depressed curb on Willow Road. The low entry points (window wells) of the four homes are vulnerable to the overland flow.
Proposed Improvements
Remove and replace the curb to a barrier type along Willow Avenue to direct overland flow eastwards towards Butterfield Road and flood proof the four homes.
Project Cost: $15,140 (2018 Dollars) Note: This cost does not include flood proofing the four private homes.
There is no Exhibit of the Existing Conditions
Existing Conditions
This existing storm sewer system has insufficient capacity. Runoff cannot effectively get to Charles Brown Park Reservoir and there are no safe overflow routes. The high-water level of the reservoir is also higher than certain roadway sags (low areas) in the neighborhood.
Proposed Improvements
Install new main line storm sewer along Rockland Road to Nicholas Dowden Park and construct laterals along Shari Lane, Dymond Road and Drake, Carter, Burdick and Ames Streets. Sewer intake and conveyance capacity will be increased. In addition, construct an 18 acre-foot detention basin in Nicholas Dowden Park - South.
Project Cost: $7,583,255 (2018 Dollars)
Existing Conditions
The existing storm sewer system has insufficient capacity and the rear yards are low in comparison to the street elevations. Storm sewer surcharging first occurs in the rear yards and the overland flow route out of rear yards is below home elevations.
Proposed Improvements
Increase the storm sewer size (conveyance and intake capacity) along Interlaken Lane and extend the sewer through the rear yards to Sherborne Court. Connect the two existing storm sewer systems along Sherborne Court and install a new storm sewer to drain Sherborne Court detention basin. Extend this new sewer and connect to the proposed sewer along Winchester Road.
Project Cost: $1,182,230 (2018 Dollars)
See Winchester Road Area for Proposed Improvements. The Winchester Road proposed improvements will need to be completed before the Interlaken Lane proposed improvements can proceed.
Existing Conditions
Runoff ponds in the roadway sag at the intersection of Elm Drive/Cook Avenue and causes home flooding in extreme instances. The existing storm sewer has insufficient capacity and safe overland flow routes are non-existent.
Proposed Improvements
Increase the size of the storm sewer along Cook Avenue to the outfall at Butler Lake. Install a new storm sewer to connect with the Elm Drive and Cook Avenue system. Also provide high capacity inlets at the Cook/Lange and Elm/Cook intersections.
Project Cost: $705,600 (2018 Dollars)
Existing Conditions
Runoff ponds in the Fourth Avenue roadway sag and causes structure flooding. In addition, due to the absence of suitable existing overland flow routes, structure flooding also results from the large tributary area to the west. The existing storm sewer system also has insufficient capacity and the existing outfalls at the Riverside Park pond are deteriorated.
Proposed Improvements
Install new, larger storm sewers along Fourth Avenue, Liberty Bell Lane and Golf Road. Connect both of these proposed storm sewer systems into the new trunk sewer along Golf Road and provide a new parallel outfall at Riverside Park. Restore the existing overland flow paths between the side and rear yards of the homes on the west side of Fourth Avenue and provide high capacity inlets on the sewer system.
Project Cost: $4,372,640 (2018 Dollars)
Existing Conditions
Water from the resulting runoff ponds in the roadway sags on Fourth Avenue, Lincoln Avenue, Windsor Terrace and Seventh Avenue make these roadways impassable and structure flooding occur as well. The existing storm sewer at Second Street and Rockland surcharges resulting in overland flow being directed towards the roadway sag on Second Street. The existing storm sewer system does not have adequate capacity and the overland flow routes through residential properties are insufficient.
Proposed Improvements
As part of the Rockland Road reconstruction project, a new main line storm sewer will be installed along Rockland Road between Prairie Avenue to the Des Plaines River. Later phases will include installing connecting storm sewers along Wrightwood Terrace, Seventh Avenue and Fourth Avenue. The proposed Lincoln Avenue storm sewer system will be connected to the Rockland Road main line storm sewer by the Wrightwood Avenue lateral.
Project Cost: $7,329,830 (2018 Dollars)
Existing Conditions
The existing storm sewer system is not properly sized in accordance with current standards. The existing detention basin is also not large enough under today’s standards and the existing storage within basin cannot be effectively accessed. Therefore, some drainage flows currently bypass the detention pond. The existing outfall for the basin is also not functioning properly.
Proposed Improvements
Increase the size of the storm sewers that drain to the existing detention basin on Stonegate Road and reconstruct basin overflow and outlet control.
Project Cost: $847,180 (2018 Dollars)
The Winchester Road proposed improvements will need to be completed before the Stonegate Road proposed improvements can proceed.
Existing Conditions
The existing high flood flows are due to a very large tributary area. The Concord-Interlaken pond overflows for extreme storm events. The existing storm sewer system has insufficient capacity. Overland flow routes are through residential side yards with insufficient capacity. Insufficient storage within the watershed and no available open space for significant new storage contribute to the flooding.
Proposed Improvements
Install a new overflow structure and modify the existing restrictors at the Concord-Interlaken pond. Install a new larger diameter relief storm sewer from the Concord-Interlaken pond along Butterfield Road and Winchester Road all the way to the eastern Cambridge-North detention basin. Modify the restrictor of the detention basin at Windhaven Road immediately south of Interlaken Ridge ponds. Install a new storm sewer just east of the ComEd right-of-way to drain the depressional area. Modify the east overflow of the Loyola Ponds. Install a new storm sewer to drain the Wilshire Court detention basin and route drainage to the eastern Cambridge North detention basin. Reconstruct the outfall at the Cambridge-North detention basin.
Project Cost: $10,104,540 (2018 Dollars)
