1. United City of Yorkville Sunflower Estates HOA SSA Town Hall Meeting August 27, 2013

2. Why we called this meeting  We are proposing to fix three detention basins in the subdivision  Basins have filled with silt and other debris, which reduces stormwater capacity  First option is to dredge the basins - $110,000 Annual SSA dues recommended to be $250 per home through 2023  Second option is to naturalize the basins - $55,000 Annual SSA dues recommended to be $150 per home through 2023  City must approve HOA SSA levy by December

3. Before we proceed… The detention basin fix and the street flooding on Walsh Circle are not related.

6. Location of Detention Basins

7. Naturalization vs. Dredging  Naturalization: Involves turning the basin into a wetland- style basin Benefits  Cheaper than dredging, both in one-time setup costs and ongoing maintenance  Naturally filters pollutants in stormwater run off  Current standard for all new detention basins in subdivisions

8. Naturalization drawback?

9. Naturalization vs. Dredging  Dredging: Simply removing the accumulated silt from the bottom of the basin Benefits  Leaves basin aesthetics as is Drawbacks  More expensive than naturalizing, both in initial cost and long-term maintenance  Must be done every 15-25 years  No plant filtration of stormwater occurs

11. Funding Cost of naturalization$55,000 Current fund balance $15,000 Amount to fund with dues$40,000 Cost of Dredging$110,000 Current fund balance $15,000 Amount to fund with dues$95,000
