SB1489 Enrolled LRB096 10752 JDS 20941 b

1     AN ACT concerning safety.
 
2     Be it enacted by the People of the State of Illinois,
3 represented in the General Assembly:
 
4     Section 1. Short title. This Act may be cited as the Green
5 Infrastructure for Clean Water Act.
 
6     Section 5. Definitions. As used in this Act:
7     "Agency" means the Illinois Environmental Protection
8 Agency.
9     "Green infrastructure" means any storm water management
10 technique or practice employed with the primary goal of
11 preserving, restoring, or mimicking natural hydrology. Green
12 infrastructure includes, but is not limited to, methods of
13 using soil and vegetation to promote soil percolation,
14 evapotranspiration, and filtration. Green infrastructure
15 includes the preservation and restoration of natural landscape
16 features, such as forests, floodplains, headwaters, and
17 wetlands. Green infrastructure also includes rain gardens,
18 permeable pavements, green roofs, infiltration planters, trees
19 and tree boxes, and rainwater harvesting for non-potable uses,
20 such as toilet flushing and landscape irrigation.
 
21     Section 10. Legislative findings.
22     (a) The General Assembly finds that:

 

 

SB1489 Enrolled - 2 - LRB096 10752 JDS 20941 b

1         (1) urban storm water, when not properly controlled and
2     treated, can cause pollution of the waters of the State,
3     threaten public health, and damage property by carrying
4     pollutants from our highways, streets, roads, parking
5     lots, driveways, sidewalks, alleys, lawns, and other
6     surfaces of low permeability into lakes, rivers, streams,
7     and ponds;
8         (2) development can increase storm water runoff by
9     increasing the size and number of paved and other
10     impervious surfaces within a watershed and decreasing the
11     extent of vegetated and other permeable surface areas that
12     control storm water runoff through natural infiltration
13     and evapotranspiration and groundwater recharge;
14         (3) current urban storm water related threats to the
15     State's water resources include pollution, increased water
16     temperatures, flooding, groundwater depletion, loss of
17     habitat, stream bank erosion, sewer overflows, basement
18     backups, contaminated drinking water sources, and
19     sedimentation of waterways; and
20         (4) some studies show that preserving and expanding
21     natural and built green infrastructure can minimize
22     negative impacts and enhance the resilience of water
23     infrastructure and water bodies.
24     (b) The General Assembly also finds that there are a number
25 of potential benefits from the use of green infrastructure,
26 including:

 

 

SB1489 Enrolled - 3 - LRB096 10752 JDS 20941 b

1         (1) Cleaner Water. Green infrastructure can reduce the
2     volume of storm water runoff in combined and separate sewer
3     systems, and the concentrations of pollutants in those
4     discharges.
5         (2) Enhanced Water Supplies. Most green infrastructure
6     approaches allow at least a portion of storm water to
7     infiltrate surrounding soil, where it recharges the
8     groundwater and stream base flows, contributing to
9     drinking water supplies and helping to stabilize aquatic
10     ecosystems. Green infrastructure systems that capture and
11     reuse storm water also help to conserve other water
12     sources.
13         (3) Reduced Flooding. Green infrastructure can help
14     control surface flooding and stabilize local hydrology by
15     reducing peak flows.
16         (4) Cleaner Air. Trees and vegetation improve air
17     quality by filtering many airborne pollutants, thereby
18     helping to reduce the incidence of respiratory illness.
19         (5) Increased Energy Efficiency. Trees and other
20     vegetation create shade, reduce the amount of heat
21     absorbing materials, and emit water vapor, which controls
22     surface temperature, thus helping to alleviate the urban
23     heat island effect. Limiting impervious surface, using
24     light colored impervious surfaces and green roofs also
25     mitigates extreme urban temperatures. By helping to lower
26     ambient temperatures and, when incorporated on and around

 

 

SB1489 Enrolled - 4 - LRB096 10752 JDS 20941 b

1     buildings, helping to shade and insulate buildings from
2     wide temperature swings, green infrastructure can reduce
3     the energy needed for heating and cooling. Green roofs and
4     shade can increase the life span of roofs, thus reducing
5     the need for production and transportation of conventional
6     roof materials. Energy use associated with pumping and
7     treating can be reduced as storm water is diverted from
8     wastewater collection, conveyance, and treatment systems.
9         (6) Mitigation of and Adaptation to Impacts of Climate
10     Change. Green infrastructure strategies can reduce energy
11     demands and, thus, greenhouse gas emissions by reducing
12     storm water volume and the associated treatment required,
13     reducing the amount of potable water needed, providing
14     thermal insulation and shade for buildings, mitigating the
15     urban heat island effect, and sequestering carbon. These
16     strategies can also help with adaptation to projected
17     climate change impacts, including increased storm
18     intensity, flood potential, and impacts on the quantity of
19     surface and ground water supplies.
20         (7) Wildlife Habitat. Stream buffers, wetlands, parks,
21     meadows, and other forms of green infrastructure increase
22     biodiversity within the urban environment.
23         (8) Community Benefits. Trees and plants improve urban
24     aesthetics and community livability by providing
25     recreational and scenic wildlife areas. Studies show that
26     property values are higher, violence is reduced, and crime

 

 

SB1489 Enrolled - 5 - LRB096 10752 JDS 20941 b

1     is reduced when trees and other vegetation are present.
2         (9) Health Benefits. Studies show that people who have
3     access to the open space provided by green infrastructure
4     in their communities get more exercise, live longer, and
5     report better health in general. Exposure to green
6     infrastructure (even through a window) improves mental
7     functioning, reduces stress, and reduces recovery time
8     from surgery.
9         (10) Green Jobs. Designing, installing, and
10     maintaining green infrastructure creates new jobs for
11     architects, designers, engineers, construction workers,
12     maintenance workers, landscape architects, landscapers,
13     nurseries, and related services.
14         (11) Cost Savings. Using green infrastructure in
15     certain situations can save or reduce (i) capital costs
16     associated with paving, constructing curbs and gutters,
17     and building large collection and conveyance systems; (ii)
18     operating and maintenance expenses for treatment plants,
19     pumping stations, pipes, and other hard infrastructure;
20     (iii) energy costs for pumping water; (iv) costs associated
21     with treatment during wet weather; and (v) costs of
22     repairing the damage caused by storm water, such as stream
23     bank restoration and flood damage.
 
24     Section 15. IEPA Study. By June 30, 2010, the Illinois
25 Environmental Protection Agency, in consultation with the

1 Illinois Department of Natural Resources, the Illinois
2 Department of Transportation, the Capital Development Board,
3 storm water management agencies, and other interested parties

12 erosion, habitat quality, and the effectiveness of green
13 infrastructure practices to achieve such standards;
14     (c) The prevalence of green infrastructure use in Illinois;
15     (d) The costs and benefits of green versus grey
16 infrastructure;
17     (e) Existing and potential new urban storm water management
18 regulatory programs and methods and feasibility of integrating
19 a State program with existing and potential regional and local
20 programs in Illinois;
21     (f) Findings and recommendations for adopting an urban
22 storm water management regulatory program in Illinois which
23 includes performance standards and encourages the use of green
24 infrastructure to achieve those standards; and
25     (g) The feasibility and consequences of devoting 20% of the
26 Water Revolving Fund to green infrastructure, water and energy
