Optimum Infrastructure Expenditure Model (OIE)andWatershed-Reservoir Wellness Index(WRWI)Version 1
Purpose of Today’s Meeting • Presentation of Tool + Our Questions • Identify Your Questions • Discuss Your Questions • Set Upcoming OIE Interactive Session Meeting
Our Questions • Can the tool help watershed management policy makers arrive at more informed decisions? • How could we improve the tool?
Background • F2F basic components • Payments for tree planting • Financial Process to connect urban water consumers with rural landowners that provides water supply related environmental services • #1 informs #2 • Today’s meeting about #2
Process • F2F timeline 2010-2012 • Tool is a crude prototype • Today is first public presentation of functionality • Next Steps: • Refine functionalities • “Hands On” testing • Refine functionalities • Deliver Products • Version 1 OIE/WRWI • F2F Report • Remaining Payments
Purpose: To determine optimum mix of green and grey infrastructure expenditures(OIE)to maximize watershed & reservoir wellness(WRWI)
Optimum(adj.) – most favorable or desirableInfrastructure(noun) -fundamental facilities and systems serving a country, city, or area, such as transportation and communication systems, power plants, and schools(Dictionary.com)
Grey Infrastructure • Dredging • Nutrient/Algae Management • Other
Green Infrastructure • Afforestation • Conservation Easements • Other
OIE • Combines financial and environmental information • Financial – infrastructure expenditures • Environmental – infrastructure unit environmental “lift” (pollution reduction) • Metric: Cost per Unit Pollutant
Both Grey and Green Infrastructure Provide Environmental Lift
Financial Information • Utility Base Rate Expenditures for Grey-Green Infrastructure • Grey Infrastructure Costs • Green Infrastructure Costs
Environmental Information • Land cover • Environmental lift calculator • Pollution budget • Reservoir water quantity and quality data
WRWI • Based on human wellness model • Fitness + Health = Wellness • Wellness means: • Fitness – land cover • Health – pollution loading
WRWI Equation • WRWI = 50 (Reservoir Health) + 50 (Watershed Fitness) • Reservoir Health = % of original storage volume • Watershed Fitness = Forest cover + Impervious Cover
Use of OIE + WRWI allows sensitivity testing to achieve optimal wellness for least cost
Generic Example • Uses data from many watersheds including SFRRW • Input information is plausible • Components crude • Easement valuation • Model timeframe • Reservoir capacity/discounting
