Will-serve letters: what the utility actually committed to
Lesson 4 of 6 · Entitle it
1 · Learn the move · Verified-data override
Every site on this rung is sold as 'utilities available'. The flyer says it, the seller's engineer said it on a call, the staff report may even say 'public water and sewer serve the area'. None of that is a commitment. The document that carries one is the will-serve letter, and it is usually narrower than anyone remembers: capacity for a stated demand, reserved or merely available today, valid for a stated period, conditioned on an extension, a fee or a board action. Verified-data override is the right shape because the task is ranking evidence. The letter, quoted, overrides every other statement about service. Everything else is labelled as a claim with its speaker. Where the letter is silent on a thing your building needs, the answer is not 'probably fine', it is [NEEDS: ...]. The model never states that a site is served, never converts a flow figure into a building size, and never says capacity is sufficient for your program. That comparison is your civil engineer's, against the letter's exact words.
The will-serve letter below is the only source of truth on service. It overrides the flyer, the call notes and the staff report wherever they differ. Extract: ISSUER | SERVICE | DEMAND STATED | RESERVED OR AVAILABLE | VALID UNTIL, AS WRITTEN | CONDITIONS. Then list every other claim about service and mark it OVERRIDDEN, CONSISTENT or NOT IN LETTER. Do not say the site is served. [letter] [flyer] [call notes]
2 · Your turn. You write the prompt
A 26.5-acre site in Draymoor County is marketed as 'served by public water and sewer'. You have the seller's flyer, your notes from a call with the seller's engineer who said 'plenty of capacity', and a two-page letter from the Draymoor Valley Utility Authority. Your program is a flex business community in three phases, many small suites with office shares anywhere from 10% to 100%, and your firm will own it for decades, so it needs water and sewer for the last building as much as the first. Write the prompt that puts the letter above everything else.
Write the prompt for this scenario as given, or swap in a real one from your own work. The score works the same either way.
