NZ community bore water-take consent costs + legume/pulse yield on LUC 4–6 (July 2026 web synthesis)

Advances RT_297 (bore-consent cost); SETTLES RT_315 (legume land-class model rule)

AI-compiled, medium. Part 2 resolves RT_315 — it confirms the engine’s existing arable cap (AF-41, analyse.py:298): harvestable pulse grain needs arable (LUC 1–3) land; a garden-scale pulse patch does NOT get the veg-garden LUC exemption. Part 1 advances RT_297 (indicative consultant breakdown, not a real quote → RT_297 stays open). Per verified-source-only, the RT_315 rule is anchored on the LUC Handbook primary (RT_325) retrieved next.

Summary

Two NZ-specific questions for the model. (1) Community bore water-take consent cost: a non-notified consent runs **~12,000–30,000 all-in** (consultant 10–19k = 24–72 hr pumping test 3–6k + hydrogeological/drawdown report 4–8k + AEE write-up 3–5k; + regional-council fees 1.5–5k), rising to **30,000–60,000+** if limited/full notification or a hearing is triggered — slightly below CR_045's 25–35k. (2) Legume/pulse on LUC 4–6 (RT_315): the LUC system draws a hard line — LUC 5–7 are not suitable for arable cropping (LUC Handbook 3rd ed); harvestable pulse/grain crops (soy, chickpea, lentil, lupin, faba) need LUC 1–3 (or screened LUC 4 units, slope <12°, free-draining), while forage legumes (clover, lotus, lucerne — oversown, no cultivation) contribute on LUC 4–6 pastoral. A ≤1 ha pulse-grain patch on LUC 5–6 cannot yield harvestable grain under any management.

Key claims

- claim: "BORE WATER-TAKE CONSENT COST (RT_297). A multi-household community bore almost always exceeds permitted-activity thresholds (region-varying, ~15–35 m³/day) → needs at minimum a non-notified resource consent (RMA). Consultant cost (excl GST, 2024–25): 24–72 hr constant-rate pumping test $3,000–6,000 + hydrogeological report (aquifer analysis, drawdown modelling) $4,000–8,000 + AEE + consent-application write-up $3,000–5,000 = subtotal ~$10,000–19,000 (firms: Allegrow, Tonkin & Taylor, Hazard Consulting). Regional-council processing fees (2024–26): Waikato $1,500–3,000; BoP Tier-3 deposit $4,000 + ~$550 pump-test fee; Environment Southland ~$987 + T&M; HBRC low-flow $287.50/consent; Auckland $2,000–5,000 deposit; annual ongoing $200–500/yr. ALL-IN: best ~$12,000–18,000 (simple aquifer, cooperative neighbours, complete non-notified app); typical ~$18,000–30,000 (drawdown modelling, 72-hr test); worst $30,000–60,000+ (limited/full notification, hearing, stream-depletion analysis). Slightly below CR_045's $25–35k. INDICATIVE (fee schedules + industry practice), not a real consultant quote → RT_297 stays open."

- claim: "LEGUME/PULSE YIELD ON LUC 4–6 — RT_315 VERDICT. NZ Land Use Capability (Landcare/AgResearch, 8 classes): LUC 1–4 arable (cropping/grazing/forestry); LUC 5–7 NOT suitable for arable cropping (pastoral grazing / tree crop / production forestry only); LUC 8 conservation only. LUC Handbook 3rd ed (verbatim): 'Classes 5 to 7 are not suitable for arable cropping but are suitable for pastoral grazing, tree crop or production forestry use.' LUC 4 = boundary (arable but severe limitations; mechanical cultivation banned on slopes >20°; only flat/well-drained pockets support pulse cropping — not the class default). HARVESTABLE grain/pulse crops (soy, chickpea, field pea, lentil, lupin, faba bean) require flat–gently-rolling terrain, free-draining soils, machinery access, pH 5.5–7 → LUC 1–3 (or explicitly screened LUC 4, slope <12°); NZ specialty-grain trials (OLW 'Six Star': soy, chickpeas, oats, buckwheat, hemp, quinoa) concentrate in Canterbury/Hawke's Bay/Marlborough (LUC 1–3); NO evidence for grain/pulse cropping on LUC 5–6 hill country. FORAGE legumes (white/red/sub clover, lotus, lucerne) do NOT require cultivation (oversown/direct-drilled into pasture) → viable on LUC 4–6; 15–25%+ of DM achievable in hill-country swards (Hill Country Futures/AgResearch). VERDICT: model harvestable pulse-grain yield only on LUC 1–3 (or screened LUC 4); forage-legume biomass/N-fixation OK on LUC 4–6. A ≤1 ha pulse-grain patch on LUC 5–6 is not viable 'under any management' — the limit is physical, not managerial."

Neobiome Intelligence relevance

• RT_315 SETTLED — the legume land-class rule. CR_052 confirms the engine’s existing arable cap (AF-41, analyse.py:298): legume_ha (the faba-grain protein crop, legume_protein_kg_ha / OT_088) is correctly capped to the arable (LUC 1–3) budget. The open question flagged in the code comment (analyse.py:285 — “whether a SMALL legume patch gets the [veg-garden] exemption”) is answered no: harvestable pulse grain is a machinery-cultivated arable crop, not a garden crop, so it does NOT inherit the veg-garden’s un-LUC-typed exemption (D29). The honest protein gap on all-pastoral parcels (AF-41, e.g. Northland 33 ha test parcel food 0.68, protein-limited) is correct. Forage legumes remain a separate, LUC-4–6-viable pathway (N-fixation/feed), not modelled as harvestable protein. No engine change — validation of existing behaviour. Primary → RT_325 (LUC Handbook).
• RT_297 advanced (not resolved) — CR_052 gives an itemized consultant breakdown (10–19k) refining CR_045's 25–35k slightly down (all-in $18–30k typical), but it is indicative (fee schedules + industry practice), not a real quote → RT_297 stays open for an actual hydrogeology-consultancy quote.

Retrieval provenance

AI-compiled synthesis (July 2026; exact tool unconfirmed), 32 web references. Values AI-extracted, unverified until spot-checked. The RT_315 rule rests on the LUC Handbook 3rd ed statement — retrieved + grep-verified as RT_325 (the follow-on primary).

Research targets

Documents to retrieve

• RT_325 — Landcare Research LUC Handbook 3rd ed (Horizons-hosted PDF): verify “Classes 5 to 7 are not suitable for arable cropping…” — the definitive primary behind the RT_315 rule + the engine’s arable cap. → RT_315 / AF-41
• RT_326 — Our Land & Water “Six Star grain & legume crops” programme report: confirms NZ specialty-grain/pulse trials concentrate on LUC 1–3 (Canterbury/HB/Marlborough); no LUC 5–6 cropping evidence. → RT_315 / RT_291

Research gaps

• RT_297 stays open (a real NZ hydrogeology/AEE consultant quote; CR_052’s breakdown is indicative). Council fee schedules fold into RT_296.
