lb CITY OF SOUTH BEND OFFICE OF THE CLERK fortunately mine is not finished, but this is another impact pathway for South Bend is basement flooding. If we look at future projections, then, for the St. Joseph River, this again shows us that these patterns of increasing risk are likely to continue. By the 2080s, again, for the RCP eight- point five(8.5) scenario, the ensemble mean shows a forty-five percent(45%) increase in the one hundred (100) year event for the St. Joseph River. This suggests that these events that were once the 2,500-year event are now much more frequent. He continued, Snow Days are likely to decline. So, we track the number of days above two (2) inches and this has some important implications. Reduced effort in cost associated with snow removal, so again, some good news there. Probably fewer school closures due to snow impact, fewer transportation impacts but there may also be loss of winter recreation activities. In particular, downhill skiing seems to be in high jeopardy. To close, heating demand we expect, not surprisingly,to go down in the winter time with warmer temperature. We see in St. Joseph County and throughout the State, perhaps, a thirty percent (30%) reduction in heating degree days which is a measure of how much energy is lost from structures due to temperatures being colder than sixty-eight (68) degrees Fahrenheit. Whereas cooling demand goes up quite substantially, multiplied by a factor of four(4).Together,though,these result in lower energy use by most people in Indiana. He went on,These are some of the impact pathways there. We may have problems with increased electrical demand in summer. For example,needing more capacity and grid reliability to be found. As I mentioned, about a five percent (5%) reduction in annual energy cost for consumers and businesses related to the fact we have thirty percent(30%)lower in the winter,which is our largest cost,but strong increases in summer. I won't go through all these conclusions which I think I have covered. I thank you very much for your attention. Co-Committee Chair Broden stated, Thank you very much. Just a note, all of these PowerPoints will be available for the public (available in the City Clerk's Office). She then called a five (5) minute recess at 6:40 p.m. The Joint Health and Public Safety and Utilities Committee reconvened at 6:45 p.m. Therese Dorau, Director of the Office of Sustainability for the City of South Bend with offices located on the 13th floor of the County-City Building, stated, I want to, now that we have been introduced to the basics of climate science and the expected impacts here in South Bend, I wanted to share a little bit about where these greenhouse gases are coming from(referencing a presentation which is available in the City Clerks' Office) here in South Bend, specifically, and how we know that. Some of this is a little technical so I might gloss over some parts, but we can come back to those in a further conversation,just to make up some of our time. She continued, So, a greenhouse gas inventory is basically an accounting exercise that measures the activities that cause emissions and then estimates the quantity of greenhouse gases from each of those activities. Like all accounting exercises, this provides municipal insight into how an organization is functioning. Also, like accounting exercises, it has a thick rule book, right and wrong,high quality and low-quality approaches. So, the value of a greenhouse gas inventory, and I'm really focusing on the value from a decision-making perspective, is that is creates a baseline that allows us to track changes and trends in emissions over time. It also helps us better understand the sources of greenhouse gases and the impacts, locally, and then identify the best emissions EXCELLENCE ACCOUNTABILITY INNOVATION INCLUSION EMPOWERMENT 455 County-City Building 227W Jefferson Bvld South Bend,Indiana 46601 p 574.235.9221 f574.235.9173 TID574.235.5567 www.southbendin.gov 15
