Computed decision comparison
Sod vs seed cost
The modeled upfront totals are $3,377 for Sod installation and $17,408 for Seed scope proxy, a difference of $14,031.
Both scenarios use 2,000 sq ft. The seed side uses the general landscaping baseline as an explicit proxy because no seed-specific rate exists in the shared store.
Side-by-side upfront cost
| Measure | Sod installation | Seed scope proxy |
|---|---|---|
| Materials | $1,538 | $8,115 |
| Labor | $1,739 | $8,593 |
| Permits | $0 | $0 |
| Disposal | $100 | $700 |
| Planning range | $2,701–$4,322 | $12,186–$28,027 |
| Typical upfront total | $3,377 | $17,408 |

Comparison questions
Which option has the lower modeled upfront cost?
Sod installation is lower in the current static default by $14,031. This compares model records, not contractor proposals.
Are 10-year and 20-year replacement costs included?
No sourced lifespan field exists in the shared baseline store, so the site does not invent replacement cycles. Those horizon cells remain explicitly not modeled.
Do both options use the same source system?
Yes. Both are computed from the current baseline store and index snapshots. Any proxy, quantity normalization, or retained legacy factor is disclosed beside the option.
