Dear Ms. Walkenbach:
As Mayor of the City of Berwyn, I would like to convey my sincere appreciation for the opportunity to
submit this application for the Illinois Green Infrastructure Grant Program. As mayor of a densely
populated, inner ring suburb I see firsthand the effects of an overworked combined sewer system such as
flooded basements, polluted waterways and damaged infrastructure.
In order to be part of the solution to these problems, the City of Berwyn seeks funding in the amount of
$1,445,765.17. This financial assistance will be used to initiate Berwyn’s Green Alley Program thus
responsibly reconstructing eight alleyways in Berwyn to include pervious concrete pavement. By
returning stormwater runoff to the ground, we hope to be able to reduce the likelihood of combined
sewer overflows; an occurrence that has become all too common.
Enclosed you will find two hard copies and a digital version of our proposal for green infrastructure.
Through your support of this initiative we hope to collectively address the amount of pollutants entering
the Des Plaines River watershed. Thank you for your time and consideration of our proposal. If you
have any questions about the plan, please feel free to contact me.
Respectfully,
Robert J. Lovero

3. City of Berwyn Green Alleys Program
Abstract:
The City of Berwyn requests $1,445,765.17 in grant funds through the Illinois Green
Infrastructure Grant Program (IGIG) to implement the Green Alleys Program. The total cost of
this project is $1,700,900.20. The City will provide the local match supporting 15% of the
project in the amount of $255,135.03. The proposed project involves reconstructing 8,480
square yards of alley space to include Pervious Concrete Pavement. These green alleys will
significantly increase permeability thus enabling 97% of stormwater to infiltrate into the
ground. Furthermore, the permeable pavement will filter stormwater runoff and reduce
pollutant concentrations. Through this project the City hopes to demonstrate to the public the
benefits of green infrastructure and sustainability.
Berwyn, as an urban infill community, has active Combined Sewer Overflow (CSO) problems
and recognizes the environmental and health risks that are associated. The proposed Green
Alleys Program will increase the amount of permeable land and therefore allow stormwater to
matriculate into the ground naturally instead of taxing the areas combined sewer system.
1. Project Narrative:
Characterization of the Area:
The City of Berwyn is located within ten miles of the Chicago Loop, situated between the
Stevenson (I‐55) and Eisenhower (I‐290) Expressways and is in close proximity to Midway
Airport, O’Hare Airport and served by the Metra Rail line. Due to its prime location and
availability of affordable housing, the City has seen an increase in population, traffic and urban
density over the past several decades.
The City’s land area is 3.9 square miles with a growing population of 56,657 in which 72% are
over the age of 18. This equates to a population density of 14,527 per square mile; 20% higher
than that of Chicago’s.
The City’s combined sewer system is nearing 100 years old and incapable, at times, of handling
the increased capacity especially during a storm. Much of the combined sewer system was
designed to handle small one story structures when pervious green areas were much larger.
While the population and density of Berwyn has grown, the combined sewer system has
remained largely untouched. Currently the City contains only 2.0% of open space. The City’s
current stormwater management system is a combined sewer system provided by the
Metropolitan Water Reclamation District of Greater Chicago (MWRDGC), comprised of a
conveyance system nearly 100 miles in length and storm laterals totaling 19 miles. Stormwater
runoff and sewage are collected into a single pipe and ultimately discharged into the large
interceptors of the MWRDGC where it is eventually treated at their Stickney Treatment Plant.

4. City of Berwyn Green Alleys Program
The Stickney Plant has the capacity to treat 1.2 billion gallons of wastewater per day, serving a
260 square mile area with 2.5 million people. This area encompasses parts of Chicago and 43
suburban communities. Many of Berwyn’s neighboring communities which are serviced by the
Stickney Plant are also built out, land locked communities with aging infrastructure.
The City of Berwyn is located within the Des Plaines River watershed. This watershed covers
over 850,000 acres of predominately urban and industrial uses within Lake, DuPage, Cook and
Will Counties. The Illinois EPA found that only 24% of the watershed was in “good” condition.
The EPA went on to attribute the primary cause of problematic conditions to municipal point
source pollution and urban runoff. Berwyn is located near a segment of the Des Plaines River
identified as a Section 303(d) impaired water body for which sources of impairment include
CSOs and urban stormwater runoff.
Although, 66% of the watershed’s land is of an urban land use, 19% is covered by forest, 5% is
cropland and the remaining 10% is open water, wetland and grassland, much of these areas
preserved by the Forest Preserve Districts. The wildlife represented in these areas is comprised
of 263 bird species, 45 mammal species, 16 species of amphibians, 22 species of reptiles, 49
species of fish, 33 species of mussels and 18 species of dragonflies. Of the species of plants
found throughout the area, 25 species are state threatened or endangered, 4 of which are on
the federal list, and one species of dragonfly is federally endangered, making the Lower Des
Plaines River basin one of few breeding places in the country.
Planning efforts are currently underway to reduce combined sewer overflows. The MWRDGC
Tunnel and Reservoir Project (TARP) is currently underway to increase the region’s capacity to
contain and direct combined sewer flows to water reclamation plants for treatment instead of
discharging into rivers and lakes. CSO communities are also implementing long‐term control
plans and aggressive pollution prevention strategies to minimize pollutant loads entering the
combined sewer systems.
Berwyn in particular is taking a multifaceted approach to addressing CSO. The City is slowly
acquiring blighted property and constructing green space called “pocket parks.” Beyond serving
as public space, the pocket parks work to increase the permeability of the entire area. The City
is working with three large commercial development projects that will include onsite detention
of stormwater runoff. Additionally, the City actively supports a rain barrel program for its
residents in an effort to further allay runoff and in the process of updating its zoning ordinance
to allow native plantings normally found in raingardens. The City is actively pursuing additional
projects that can be implemented to reduce flooding, stormwater runoff and CSOs. The City
recently replaced a 25,580 square foot asphalt parking lot for a Park District facility with
permeable pavers. In addition, a StormTrap underground stormwater storage system was

5. City of Berwyn Green Alleys Program
installed in a park in a section of the City that experiences flooding regularly, designed to
provide 5,507 cubic feet of underground storage.
Project Need:
The City has experienced several instances of damaging flooding over the past couple of
years. The City’s combined sewers are outdated and were not originally designed to sustain the
demands of a growing urban area. The Green Alley Program is intended to provide storm sewer
relief to the City’s combined sewer system by providing detention and percolation areas in the
alleys. The City is looking to redevelop these areas using a green pavement solution as a way to
mitigate flooding concerns as well as prepare for the future. Over the past couple of years, the
City has experienced severe flooding events resulting in hundreds of thousands of dollars in
damage and the displacement of residents from their homes.
Berwyn’s stormwater and sanitary sewerage is conveyed to the MWRDGC interceptor system.
Most of these City collection sewers have a very limited capacity to convey stormwater runoff
due to their small size and long distances to the MWRDGC interceptor. During heavy rainfall
events, MWRDGC has been forced to close the sluices gates to their system and excess flows
are diverted into the surrounding waterways untreated.
Pervious Concrete is a highly effective on‐site stormwater management practice and
considered amongst the Best Management Practices (BMPs) of the EPA. Berwyn is hopeful that
the Green Alleys Program will reduce the volume of stormwater entering the combined sewer
system by 97%. Surface runoff entering the green alleys will infiltrate the ground rather than
end up in the combined sewer system. This initiative will also reduce pollutant loads entering
both the City system and the MWRD system and will ultimately reduce the discharging of
pollutants into the area waterways. Thus, the Green Alleys Program will help improve local
water quality in the long term.

The chart above indicates the number of pollutants in the surrounding waters that can be
attributed to CSOs and stormwater runoff. The capacity of the existing system is exceeded
during heavy rainfall and has been the case of flooding within the City. The City wishes to
pursue future projects to aid in stormwater management.
Project Plan:
The City of Berwyn proposes to utilize IGIG funds to initiate the Green Alleys Program and
reconstruct eight (8) concrete alleys totaling 8,480 square yards. The proposed green alley will
have an alley section that is sloped to a center section composed of pervious concrete above an
aggregate base. The total pervious concrete area for this project will be 2,200 square yards.
The locations are as follows:
1. Alley 13th Street to 14th Street – Oak Park to Euclid Avenues
2. Alley 18th Street to 19th Street – Wisconsin to Wenonah Avenues
3. Alley 18th Street to 19th Street – Wesley to Clarence Avenues
4. Alley 19th Street to 21st Street – Harvey to Lombard Avenues
5. Alley 23rd Street to 24th Street – Euclid to Wesley Avenues
6. Alley 29th Street to 30th Street – Harlem to Maple Avenues
7. Alley 37th Street to 38th Street – Grove to Oak Park Avenues
8. Alley 37th Street to 38th Street – Cuyler to Highland Avenues
Project Components:
The project will consist of existing alley pavement removal, earth excavation, installation of the
aggregate base courses, geotechnical fabric, and installation of a concrete with pervious
concrete alley. The construction of the 8 alleys will take approximately 3 months to complete.
Berwyn will begin implementation upon notification that this application has been approved for
IGIG funding. The key project components are:
