not limited to:
1. lnappropriate floodplain uses and development have increased flood risk, flood
damage, and environmental degradation;
ARTICLE l AUTHOR!Tγ AND PURPOSE
Page l-1
2/15/18
2. lt is necessary to consider stormwater management on a watershed basis;
3. Cook County lands drain poorly due to generally flat topography and soils of low
permeability;
4. Many land development practices alter the natural hydrologic balance of Cook County
streams;
5. Wetlands play an essential role in flood storage, floodplain management, sediment
control, and water quality enhancement;
6. Riparian environments may be effective in reducing flow rates and volumes in addition
to providing stream bank erosion protection and water quality enhancements;
7. Many stormwater facilities are not adequately maintained;
8. While the District has required stormwater detention in separate sewer areas since
t972via the Sewer Permit Ordinance, flooding continues to be a concern in Cook
County due to the increased volume and rate of stormwater runoff resulting from
continued development;
9. Stormwater detention requirements for new developments alone do not address the
impacts of transportation and other improvements; and
10. lnfiltration and inflow contributes to basement backups, sanitary sewer overflows, and
excessive flows to the District's water reclamation facilities.
$ 103, Purposes of this Ordinance
The purpose of this Ordinance is to effectuate the purposes and intent of the Metropolitan
Water Reclamation District Act (70 ILCS 2605/1 et seq.) by:
1. Protecting the public health, safety, and welfare, and reducing the potential for loss of
property due to flood damage;
2. Managing and mitigating the effects of urbanization on stormwater drainage
throughout Cook County;
3. Protecting existing and new development by minimizing the increase of stormwater
runoff volume beyond that experienced under existing conditions and by reducing
peak stormwater flows;
4. Promoting responsible land use practices in Cook County, particularly within
floodplains and floodways;
ARTICLE l AUTHORITY AND PURPOSE
Page l-2

5. Protecting existing water resources, including lakes, streams, floodplains, wetlands,
and groundwater from detrimental and unnecessary modification in order to maintain
their beneficial functions;
6. Reducing or mitigating the environmentally detrimental effects of existing and future
runoff in order to improve and maintain water quality;
7. Preserving and enhancing existing riparian environments;
8. Controlling erosion and the discharge of sediment from all sources including, but not
limited to, stormwater facilities, waterways, developments, and construction sites;
9. Requiring appropriate and adequate provisions for site runoff control;
10. Requiring consistency in stormwater management activities within and among the
units of government having stormwater management jurisdiction;
11. Ensuring future development in the floodplain does not adversely affect floodplain
environments or increase the potential for flood damage;
L2. Requiring regular, planned maintenance of stormwater management facilities;
13. Encouraging control of stormwater quantity and quality at the most site-specific or
local level;
14. Establishing uniform and minimum countywide stormwater management regulations
while recognizing and coordinating with stormwater programs effectively operating
within Cook County;
15. Requiring strict compliance with and enforcement of this Ordinance;
16. Meeting the floodway permitting requirements of the lllinois Department of Natural
Resources, Office of Water Resources, delineated in the Rivers, Lakes, and Streams Act
(61s lLcS s/18e);
17 . Complying with the rules and regulations of the National Flood lnsurance Program
(NFIP) thereby making federally subsidized flood insurance available;
18. Protecting the ability ofthe District's sewerage systems, intercepting sewers, TARP

§ 800.
§801.1ARTICTE 8. TNFTLTRATTON / TNFLOW CONTROL PROGRAM
Introduction
The separate sanitary sewers within the District's service area are designed and
intended to receive and convey only domestic and industrial wastewaters together with
a limited amount of groundwater infiltration. Stormwater runoff and excessive
groundwater infiltration, however, have in many cases been entering and overloading
sanitary sewers through deficiencies in the sewer systems such as open pipe joints,
cracked or broken pipes, leaking manholes, and illegal connections (i.e., direct or indirect
stormwater/groundwater connections to separate sanitary sewers). Sewer overloading
arising from such deficiencies may cause health hazards, financial losses, and
inconvenience to area residents. These detrimental conditions occur as a consequence
of water pollution from treatment plant bypasses and sewage overflows into streams,
and also as a result of backups of sewage into buildings and onto streets and yards.
Excessive extraneous clear water flows also result in additional sewage treatment costs
to the public. Since the enactment of the 1985 Sewer Summit Agreement (SSA), many
communities have invested in rehabilitation efforts yet the sewer systems still have
excessive stormwater inflow and groundwater infiltration (l/l) requiring further
reduction. Many communities still need to establish on-going maintenance programs
and budgets that continually renew localsystems. The lllinois Environmental Protection
Agency (IEPA) has imposed a special condition as part ofthe District's National Pollutant
Discharge Elimination System (NPDES) Permits that requires the owners and/or
operators of separate sanitary sewer systems that discharges directly and/or indirectly
to the District's facilities (satellite entities) to implement measures in addition to those
required under the SSA if excessive l/l causes or contributes to sanitary sewer overflows
(SSOs) and/or basement backups (BBs). ln order to address the requirements set forth
in the NPDES Permits and other federal, state and local regulatlons, it is the intent of this
Article to set forth a regionally applied lnfiltration/lnflow Control Program (Program) for
the rehabilitation and correction of sanitary sewer system deficiencies, and for the
continuation of adequate long-term sanitary sewer management and maintenance
programs by the satellite entities that are tributary to the District's facilities.
Scope and Goals
The purpose of this Program is to provide a framework for asset management of
separate sanitary sewer systems to meet the following goals:
A. Maintain infrastructure to prevent sanitary sewer overflows and basement
backups due to sewer surcharging and other adverse sewer system conditions.
ARTICLE 8 :NFILTRAT10N/INFLOW CONTROL PROGRAM
PAGE 8-1
2/15/18
B. Comply with the District's NPDES Permits and all other applicable federal, state,
and local laws and regulations.
C. Minimize extraneous flows transported to the District's facilities due to defective
system components or illegal connections.

Substantial lmprovement
Determined by the local municipality in accordance with NFIP regulation. FEMA defines substantial
improvement as "Any repair, reconstruction, rehabilitation, addition, or other improvement of a
building, the cost of which improvement equals or exceeds, individually or in the aggregate, fifty
percent (50%) of the fair market value of the building, determined from the equalized assessed
value of the building before the start of construction of the improvement. This term includes
buildings which have incurred "substantial damage", regardless of the actual repair work
performed." The term "cost of improvement" includes the market value of volunteer labor and
donated materials. The term "cost of improvement" does not, however, include either (a) any
project for improvement of a building to correct existing violations of state or local health, sanitary,
