Payment calculations for the Phase 1 Distribution of the Gross Reservoir Community Mitigation Fund were achieved by utilizing rankings from an environmental analysis study conducted by Pinyon Environmental, Inc. (Pinyon report). The Pinyon report ranks three environmental impacts: Noise, Air Quality, and Visual/Lighting.
The final household rankings in the report were formatted to show only one decimal point, however, more precise/multiple decimal points were used for the Air and Noise calculations resulting in some households with the same total ranking having a different payment amount.
Payment Calculations:
The Community Working Group, in its report and recommendations (pp. 8-10), agreed to an impact WEIGHTING SYSTEM of 35% Noise, 30% Air Quality, and 35% Visual/Lighting (which were the proposed weights in the Pinyon report), and the Board of County Commissioners accepted that recommendation. Noise and Air Quality rankings were computed at precise numbers extending to multiple decimal points. Visual/lighting impacts (if present) were calculated at a whole number of 1-5 based on distance ranges.
The final payment calculation (for total rankings 2.6 and above) is =(NOISE*0.35+AIR*0.3+VISUAL*0.35) X Multiplier (i.e., point value based on the $4 million distribution). In other words, the dollar calculation is based on the SUM of the calculations of the three WEIGHTED factors X MULTIPLIER.
Summary: The extended decimal rankings for Air and Noise and the individual weightings for each factor determined a more precise and accurate disbursement amount for each individual household.
