2 Prior Efforts / Reviews 1997 Citywide Analysis Too big, too long, unaffordable Series of 4 Council Briefings Four potential courses of action identified No formal council action 2

3 Hybrid Alternative: Individual neighborhood SSD s, specific scopes and timelines (3 cycles, 16 years) Includes City funded Spur Channels (early appropriations allow for 1 st dredging in year 2) Partnership Cost sharing (3 sources) City management of effort formulation, funding, design, permitting, construction, maintenance Creates a viable solution to reclaim navigation & improve water quality Establishes a reasonable timeline with visible results 3
