1. UGLSP – Supplemental Slides Development of an Assessment Tool to Evaluate Impacts to Shore Protection Infrastructure due to Fluctuating Water Levels (RFP 04-200) Burlington 6 November 2010 Mike Davies

2. Site 22 (Chicago) plan response for high and low levels This plot shows results at only one analysis site (Site 22, Chicago). The average cost of shore protection ownership ($/m) is shown for a low level period (the 1960s) in blue and a high level period (1980s in red).

3. Basin-wide response plan response for low level period This plot shows results at all 25 sites The relative cost of shore protection ownership (as compared to p77a) is shown for a low level period (the 1960s). Superior Huron Michigan

4. Basin-wide response plan response for high level period This plot shows results at all 25 sites The relative cost of shore protection ownership (as compared to p77a) is shown for a high level period (the 1980s). Superior Huron Michigan

5. Plan Ranking by Lake and Measure (1=best, 6=worst) - No weighting applied here, so results do not reflect the in place density/value of shore protection

6. Plan Ranking with Weighting Weighting “Even” – no weighting “1” – weighted by the ratio of shore protection on the lake “2” Extreme weighting – indicative of including factors like population density Weighted Results
