To find the total 15-year per capita cost of the Pocahontas County Solid Waste Transfer Station project, we separate the expenses into two categories: fixed capital infrastructure costs (shared across the total population) and the individual accumulated user fees over the 15-year duration.
Based on current demographic tracking, the population of Pocahontas County ranges from the 2020 Census count of 7,869 to the 2025 Census estimate of 7,602, down to a 2026 projection of 7,564 residents.
1. Total Base Infrastructure Costs
These represent the macro project expenditures over the 15-year operational lifecycle:
Landfill Purchase: $157,000
Transfer Station Construction/Cost: $4,100,000
15-Year Lease Total: $2,700,000 ($15,000 per month × 12 months × 15 years)
End-of-Term Buyout: $1,000,000
Total Fixed Capital Investment: $7,957,000
2. Individual Operational Cost (15-Year Service Fee)
If an individual resident pays the projected annual garbage service fee of $310 continuously over this period:
15-Year Accumulated User Fee: $310 × 15 years = $4,650.00
Per Person Cost Breakdown by Population Scenario
The per capita impact of the $7,957,000 infrastructure investment shifts depending on the population baseline used as the denominator. Adding the $4,650 individual service fee yields the total projected 15-year personal cost:
Scenario A: Using the 2025 Census Estimate (7,602 Residents)
Infrastructure Share per Person: $7,957,000 ÷ 7,602 = $1,046.70
Accumulated User Fee: $4,650.00
Total 15-Year Per Capita Cost: $5,696.70
Scenario B: Using the 2026 Population Projection (7,564 Residents)
Infrastructure Share per Person: $7,957,000 ÷ 7,564 = $1,051.96
Accumulated User Fee: $4,650.00
Total 15-Year Per Capita Cost: $5,701.96
Scenario C: Using the 2020 Census Baseline (7,869 Residents)
Infrastructure Share per Person: $7,957,000 ÷ 7,869 = $1,011.18
Accumulated User Fee: $4,650.00
Total 15-Year Per Capita Cost: $5,661.18
