Optimum Infrastructure Expenditure Model (OIE)andWatershed-Reservoir Wellness Index(WRWI)Version 1

purpose of today s meeting
Purpose of Today’s Meeting
  • Presentation of Tool + Our Questions
  • Identify Your Questions
  • Discuss Your Questions
  • Set Upcoming OIE Interactive Session Meeting
our questions
Our Questions
  • Can the tool help watershed management policy makers arrive at more informed decisions?
  • How could we improve the tool?
background
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
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
slide6
Purpose: To determine optimum mix of green and grey infrastructure expenditures(OIE)to maximize watershed & reservoir wellness(WRWI)
slide7

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
Grey Infrastructure
  • Dredging
  • Nutrient/Algae Management
  • Other
green infrastructure
Green Infrastructure
  • Afforestation
  • Conservation Easements
  • Other
slide10
OIE
  • Combines financial and environmental information
    • Financial – infrastructure expenditures
    • Environmental – infrastructure unit environmental “lift” (pollution reduction)
  • Metric: Cost per Unit Pollutant
financial information
Financial Information
  • Utility Base Rate Expenditures for Grey-Green Infrastructure
  • Grey Infrastructure Costs
  • Green Infrastructure Costs
environmental information
Environmental Information
  • Land cover
  • Environmental lift calculator
  • Pollution budget
  • Reservoir water quantity and quality data
slide14
WRWI
  • Based on human wellness model
  • Fitness + Health = Wellness
  • Wellness means:
    • Fitness – land cover
    • Health – pollution loading
wrwi equation
WRWI Equation
  • WRWI = 50 (Reservoir Health) + 50 (Watershed Fitness)
    • Reservoir Health = % of original storage volume
    • Watershed Fitness = Forest cover + Impervious Cover
generic example
Generic Example
  • Uses data from many watersheds including SFRRW
  • Input information is plausible
  • Components crude
    • Easement valuation
    • Model timeframe
    • Reservoir capacity/discounting
