be hosting any this year.
Engelhardt commented that no City-owned building will accommodate the size and scope of this
event. Boettcher stated the Public Works Director said that tarps or tents will be the way to go.
Suggestions for possible sites include visitation of all possible City locations and large parking
lots, Kendall County Department of Solid Waste, and checking with Oswego's ECO group,
Goodwill parking lot, and the Kendall County Fair Grounds. It might be possible if the City
partnered with the County to get a discount on the Fair Grounds. Engelhardt will also check the
City's event calendar and School Dist 115 calendar. The committee will keep Mayor Burd
informed of any progress in the investigation.
Keane talked about changing the mindset of society to change environmental behavior to become
more conservative and less wasteful. Jewel in Downers Grove had a reminder prompt at their

2. Tree City Recommendation (Richard) Boettcher reported that a grant from CEMAP was
received and work will begin on the project this summer.
The standard for the grant is $2.00 per person. Based on the recent census, the population of
Yorkville is16,813, which means the city will be required to spend $33,626. The City met the
funding requirement last year; it is necessary to see if the city will meet the requirement for 2009.
The recommendation to apply for the Tree City designation needs to go to a City committee.
All the work will be done by City staff with GPS systems and with the help of interns (college
students).
3. Franchise Agreement Recommendation
4. Electronic Recycling Perm Program progress (Stephanie) --
Manthei requested that the Green Committee have a progress report in May.
5. Budget Line Item for Environmental Education that allows Fundraising (Richard)
Boettcher explained that the procedure will involve approval from Mayor and approval by City
Council for all fundraising for all fundraising efforts and for all expenditures of the money raised.
Boettcher requested that the Green Committee at the May meeting have a discussion with the
Mayor as to handle fundraising efforts. Lee asked for a list of guidelines for raising funds and
for spending the funds raised before discussion with the mayor. Boettcher suggested waiting
until after talking with the Mayor before drafting a list of guidelines.
Old Business:
1. Zoning Ordinance Committee Update(Al)
2. Kendall County Solid Waste Committee (Marta)
3. Wind Turbine Ordinance Progress
Scheffrahn summarized the discussion at the Public Works Committee. A small system
produces .4 kilowatts at its maximum. The roof top systems are available for purchase at
Menards. The ordinance, which is highly restrictive for roof top systems, is being handled
similarly to the regulations for satellite dishes. One roof-top will be allowed by the ordinance
with a regular permit. Additional rooftop turbines will be required with a special permit.
Large systems are intended to be used for generating power to be sold back to the electric utility
grid.
All the ordinances will be reviewed in more depth; developing the codes for the purpose of
control .
Lee motioned that the Green Committee write a letter to the City council stating that the
Green Committee supports the concept of an ordinance for wind turbines to generate
alternative energy. Keane seconded. Vote: All "yes." Keane will write the letter.
Additional Business:
May 4th is the next Economic Development committee.
Lee requested Green Committee add "events" to the Yorkville Green Events Calendar. These
should be sent to Glory Spies.
Next meeting of the Yorkville Green Committee is Monday, May 18.

REPORT SUMMARY
YORKVILLE GREEN COMMITTEE
May 18, 2009 Meeting
Mission Statement: To advise the City Council of the United City of Yorkville, Illinois on ways to enhance the
community environment and ways to equip and encourage citizens and businesses to participate in sustainable
ecological practices.
Committee Reports:
Education Committee Report - We continue to request more articles (500-600 words) on a wide array of
topics. It was agreed that each member of the Green Committee would complete at least one article. Editing will
be done after submission, so please submit something by June 15`h to Marta or Anne.
Cutting CO2 Articles — Last month each member of the Committee was additionally asked to submit a
paragraph to Marta or Anne on something that they have done to reduce carbon dioxide, the short experiences
could be put into an article that all families might find personally useful. Please submit by July 15`h to Marta or
Anne.
A recommendation was submitted requesting two new "green related" links be added to the City of
Yorkville's website and Glory responded that these links would be added. Submitted by Marta Keane
Water Conservation Committee — The three recommendations calling for specific changes to existing
ordinances were forwarded to the Mayor on Sunday, March 22, 2009. They have not made any apparent progress
as yet, still waiting for them to be referred to a subcommittee (expect it to be Public Works). Submitted by Al
Green
Plastic Bag Reduction— Three recommendations based on Committee action at the April meeting were sent to
the Mayor on Tuesday, May 12, 2009 related to the Plastic Bag Reduction issue. One called for recognition letters
to be sent to the newspapers regarding Ace and Target's "free" distribution of reusable bags in honor of Earth
Day. Another proposed a special recognition for Aldi when they reopen for their fee based bag program that
reduces the number of disposable bags customers use. The third recommendation was for an open letter to be sent
to local retailers and newspapers calling for retailers to do more to encourage customers to use reusable bags.
Submitted by Marta Keane
Environmental Fair Committee—No information provided this month
Share & Care Recycling Event Committee — After researching the possible sites, City-owned buildings, and
various parking lots, and rental costs for either frame tents or canopies, it truly does appear that the best possible
site for this event will be Smith Hall on the Kendall County Fairgrounds.
The City buildings are either not available (used for storage) or not large enough. The parking lot in the in the
vacated commercial area in Countryside Center is in extreme disrepair, with many large and deep potholes. Other
large parking lots are owned by the school district or businesses, which would require a contract for use. In
addition, the main disadvantage in using a parking lot is that the event will be exposed to the weather, which is
unpredictable. Given the type of event this is intended to be, many of the materials accepted must be protected
and therefore, if the event were to be held outdoors, tents or canopies would be required.
Checking with three different rental companies that service the Yorkville area, we learned that the rental cost of a
frame tent to cover 20' x 100' will range from $1,056 to $1,400; the canopy tents would cost $635, plus set-up
costs; and the pole-style tents would cost $1,095 plus set up costs.
Conversely, if we consider the rental of Smith Hall(as was done in 2008), there are great benefits beyond cost.
1. No delivery; no set-up, no take down
2. Completely under cover--will be very valuable to both volunteers and the citizens who participate. Plus, if we
add the "share" feature-there needs to be space to browse the items.
3. Drive through convenience
4. Location is designed for car traffic
5. Vendor parking is convenient to large doors (especially large trucks, like Goodwill's semi)
6. Ground space for E-waste
7. Restrooms available
8. Electricity available- if needed
9. 200'x 60' is the estimated covered space, larger than tent space.
10. COST: $600.00 without any reductions or waiver
In addition, the Yorkville Green Committee may be able to work with the County to develop a partnership that
can reduce costs and share the responsibilities. This event is publicized in local papers and the school district. By
the nature of such advertising, we bring in participants from outside the municipal boundaries. It is in our best
interest to partner with the County to offset our costs for this event if possible regardless of the location selected.
Anne has made a contact with Mike Drendle, President of the Kendall County Fair Association, and learned that
Smith Hall is available on October 24`h,but NOT on Oct. 17`h
Based on discussion at the May Green Committee meeting and consent of the Mayor, Marta shall submit a
recommendation that the City Council give its approval for the Green Committee to move forward on the next
Care & Share event to be held at Smith Hall on the date of Oct. 24, and that we begin to work with the Kendall
County Department of Solid Waste for funding and publicity assistance.

Recommendation Progress Reports:
Tree Survey Recommendation—Nothing New to Report. Submitted by Stephanie Boettcher
Tree City Recommendation - A recommendation supporting the pursuit of a "Tree City" designation for the
City of Yorkville was submitted to the Mayor in November, 2008. It was dependent on the City's funding for tree
preservation and planting. It was hoped that based on the success of the grant for the Tree Survey to be done, that
this efforts would move forward. As of now, we are still waiting for it to be referred to a subcommittee(expect it
to be Public Works). Submitted by Marta Keane
Franchise Agreement Recommendation—A recommendation supporting the pursuit of a Commercial Franchise
Agreement was submitted to the Mayor on February 4, 2009. They have not made any apparent progress as yet,
still waiting for them to be referred to a subcommittee(expect it to be Public Works). Submitted by Marta Keane
Electronic Recycling Permanent Program progress - The program is up and running at the Public Works
Building(610 Tower Lane). The public works department reported that the service has been going well and there
have already been three pick-ups of the contents of the Gaylord box, so about every 2—3 weeks. There are daily
drop-offs by residents and overall they seem to be pleased with the service. Currently, Saturday drop-off times
are not possible due to the budget. Submitted by Stephanie Boettcher
Budget Line Item for Environmental Education that allows Fundraising—No action has been taken as yet to
pursue revenue or expenses related to this new budget recognition.
Recycling in Parks, Athletic Fields, etc. — A recommendation was sent to the Mayor on May 12, 2009
requesting information on the City's contract and ability to provide recycling collection service to highly utilized
parks and athletic fields, as well as all City facilities. To date, no information has been provided on this request.
Submitted by Marta Keane
Old Business:
Zoning Ordinance Commission— The second meeting was held April 29. The Zoning Ordinance Assessment
Report was reviewed in some detail. Various additional issues were raised by commission members for more
discussions later. In addition to the Wind Energy Systems chapter, there may also be a chapter added for Solar
Energy Systems. Submitted by Al Green
Kendall County Solid Waste Committee—As reported previously; the Solid Waste Committee will be meeting
in June (to discuss transfer stations & landfill) and in August (to finalize the entire document). Following the
August meeting, the Kendall County Board will be reviewing and discussing the document. It is anticipated that
there will be a public meeting with hopes of passing the Updated Kendall County Solid Waste Plan by the end of
2009.
Wind Turbine Ordinance—This effort was broken down into 3 separate proposed ordinances, for rooftop, small
and large systems. Small & Large system ordinances are still under development. The"mid-size"rooftop system
ordinance was forwarded by the EDC for consideration at the May 12 Council meeting for first reading. A
second reading of the ordinance is scheduled for the May 26 City Council Meeting. The City Council can vote on
the ordinance at this meeting, or can table the vote to another meeting. The small wind energy systems ordinance
is planned to be discussed that the June Economic Development Committee meeting on June 2. If committee
members are interested in attending the EDC meeting, staff suggests looking that the EDC agenda online prior to
the meeting to ensure it is an agenda item. http://www.yorkville.il.us/ og v mtgs minutes.php Submitted by Al

Green Your Home for Your Health: Emissions and Indoor Air Quality
Quality
Submitted by Cheryl Lee
While sustainability and energy efficiency often dominate the green building
conversation, the issue that can have the most immediate impact on your family's health
is indoor air quality. Green building programs seek to limit your family's exposure to
Volatile Organic Compounds, or VOCs, that exist in some building materials and
furniture. Continued exposure to these VOCs has caused health problems ranging from
headaches and nausea to cancer. Green building programs like the US Green Building
Council's LEED for Homes and LEED for New Construction encourage builders to
eliminate these emissions whenever possible,
If building green comes at a slightly higher cost it is because many of these harmful
chemicals are so widespread that finding products without them can be a challenge. In
fact, it is the presence of these chemicals in some products that makes them cheaper, as in
wood products containing urea-formaldehyde.
Those looking to improve the indoor air quality of their current house can make several
changes that will significantly reduce VOCs. The following are some sources of harmful
emissions in the home:
Composite Wood Products
Urea-formaldehyde is used to expedite the gluing process of composite wood like
plywood and particle board, allowing more to be produced. Unfortunately, urea-
formaldehyde is a health risk and a known carcinogen. When purchasing wood building
material, cabinets, and wood furniture, seek those with no added urea-formaldehyde.
Several particle board manufacturers use no urea-formaldehyde in their process. There
are cabinet companies that offer cabinetry with no added urea-formaldehyde.
Carpets
Carpets can be a double whammy when it comes to VOCs. Synthetic carpets, as well as
the padding and adhesives, are loaded with VOCs and the American Lung Association
reports that some people experience eye, nose, and throat irritation, headaches, skin
irritation, and cough as a result. Carpets also act as a "sink" for such pollutants as
pesticides, dust mites, and fungi. Alternatives include carpets certified as no VOC, hard
wood (as long as its formaldehyde free,) and linoleum, which is hypoallergenic and is
made from renewable resources.
Paints, Caulks, and Adhesives
Building products that require drying, like paints, caulks, and adhesives, use a solvent
that evaporates into the air (and possibly into our lungs.) If the solvent is synthetic, those
chemicals used in the creation of the product become airborne. Many companies have
moved away from synthetic solvents toward a water based product. Older homes should
be checked for lead paint.
Proximity of Carbon Monoxide Sources
The two primary causes of carbon monoxide are cars and cigarettes. If the garage is
attached or located under the house, carbon monoxide can make its way up into the house
if the car is left on. Cigarette smoke in the house or near windows can contribute the
levels of carbon monoxide in a home. Sensitivities vary but the most common early
symptoms include headache and dizziness. Prolonged exposure can lead to death.
Other Sources of VOCs:
• Mattresses with synthetic or chemical based foam
• Nylon furnishings, which may contain the carcinogen benzene
• Rubber or leather products that contain xylene
• Household cleansers high in chemicals
• Stored gasoline and solvents
VOC Warning and Removal
Several indoor air quality tests are available, including carbon monoxide detectors.
Efficient ventilation systems can mitigate the amount of VOCs in the home. Check out
the EPA's site on indoor air quality (http://www.epa.gov/iaq/voc.html#Sources) for more
info.

How To Lower Your Energy Bills
Submitted by Cheryl Lee
2008 was the year that saw elements of green building become mainstream and increased
interest in green technologies. But for those who are not building a new house or who
don't keep up with all the new technologies, there are many simple, inexpensive (or free)
ways to green your life that you can do right now. The result will be a more energy
efficient, healthier and more sustainable environment for you and your children.
Take your recent energy bills and spend the next 30 days tweaking your habits to lower
your energy bills. Compare the February bills to the January bills. There are several
ways to buy your way into lower electric bills, like replacing old refrigerators or getting a
tankless water heater, but if the point is to save money now, here are some instant energy
and money saving ideas:
• Close doors and vents in rooms you don't use
• Turn off electronics when not in use and unplug appliances with phantom loads
• Replace incandescent lights with CFLs - and keep lights off when you don't need
them
• Make sure furnace filters are clean - and keep dryer filters clean
• Program the thermostat to run cooler at night when you are snug in your bed
• When possible, wash clothes in cold water
• Shorten showers
• Check for drafts around doors and windows
• Wash only full loads of laundry and dishes
• Replace old shower head with an inexpensive low-flow fixture
• Install an aerator (less than $15) in bathroom faucets to lower water usage
Find out if your energy company will perform a free energy audit in your house. It will
help isolate which areas of the house are losing the most energy and help you with
strategies to conserve energy.

What is a "Carbon Footprint"?
Submitted by Cheryl Lee
A carbon footprint is a measure of the impact our activities have on the environment, and
in particular climate change. It relates to the amount of greenhouse gases produced in our
day-to-day lives through burning fossil fuels for electricity, heating and transportation
etc. This measurement has units of tones (or kg) of carbon dioxide equivalent. The impact
on the environment in terms of the arnount of greenhouse gases produced, measured in
units of carbon dioxide. Available soon from the Green Committee of the City of'
Yorkville is a program to calculate your family's Carbon Footprint in order to shove areas
that can yield the greatest reductions in your-`carbon lbotprint".

A carbon footprint is made up of the sum of two parts, the primary footprint (shown by
the dark grey slices of the pie chart) and the secondary footprint (shown as the light grey
slices).
1. The primary footprint is a measure of our direct emissions of CO2 from the burning
of fossil fuels including domestic energy consumption and transportation (e.g. car and
plane). We have direct control of these.
2. The secondary footprint is a measure of the indirect CO2 emissions from the whole
lifecycle of products we use - those associated with their manufacture and eventual
breakdown. To put it very simply — the more we buy the more emissions will be caused
on our behalf.

What is Global `Farming?
Submitted by Cheryl Lee
Global warming is the increase in the average temperature of the Earth's near-surface air
and oceans since the mid-20th century and its projected continuation.
However, the phrase 'cliinate change' is becoming the preferred phrase instead of'global
wanning' because it helps convey there are climate changes in addition to rising
temperatures. The science of global warming is well understood. Certain gases,
especially CO2, absorb solar radiation that would otherwise be dissipated back into
space. Like a down comforter on your winter bed, these gases then radiate heat back to
the earth. The more of these gases in the atmosphere, the more energy radiated back to
earth. The higher the percentage of carbon dioxide in the atmosphere, the greater the
amount of the sun's energy}' that is trapped on earth. While rising sea levels threaten our
shorelines, increased storm surges and extreme wind events become matters of concern.
Declining soil moisture will mean lost agricultural productivity and more frequent
droughts, pests and forest fires.
FACT: The levels of('02 have risen from 280 parts per million in pre-industrial times to
382 ppin today.
FACT: The earth's surface temperature increased 1,33 f 0.32 °F between 1905 and 2005.
