8 NS communities (~1,210 ac) + Kahuku (~420 ac) + ʻIliʻili (~8 ac)
1. Otake Farms —
Very High
| Acres | ~55 (within Kaala Ranch TMK) |
| Operators | 7 farming families (Laotian, Cambodian) |
| Structure | Licensed operators on private land |
| TMK | 66027010 |
Flood waters carried river debris with horizontal velocity across farmland. 1–4 ft of non-farmable silt/mud deposited over topsoil. Hazardous debris (glass, metal, pipes) embedded in fields. All farmers derive 100% of livelihood from farming.
Scope: Surface debris removal (~7,168 CY), embedded debris extraction (~40 ac), compost amendments (100–150 CY/ac), deep ripping/subsoiling.
Key issues: Irrigation system damage (broken pipes, pressure issues), road gravel washed out, soil contamination testing pending, beetle pepper die-off.
2. Mill 6/10 —
Very High
| Acres | 287 (3 TMKs) |
| Operators | 139 lots, multiple co-ops |
| Structure | Subdivided ag lots, licensed operators |
| Owner | Savio Waialua Farmland, LLC |
| TMKs | 67001072 · 67001037 · 67001074 |
| Ditch LF | 15,363 (GIS) / 16,000–17,000 (SOW) |
Plantation-era ditch network unmaintained for decades. California grass and bamboo raised ditch bottoms. Unauthorized crossings and undersized culverts create chokepoints.
Scope: Ditch clearing ~16,000–17,000 LF, culvert/blockage clearing at multiple locations, upstream erosion source identification.
Key issues: Farm access roads impassable in rain, individual farmer crossings blocking flow, bottleneck points backing water up to upstream farms. Ditch clearing confirmed as qualifying for debris removal funding.
3. Mahiko Farms —
High
| Acres | 333 |
| Operators | 88 lots / ~75 owners |
| Structure | Subdivided ag lots (1–2 ac each) |
| Owner | Mahiko Farms Partnership (Taogoshi / Aiea Realty) |
| TMK | 68006010 |
| Ditch LF | 11,375 (GIS) / 11,000–12,000 (SOW) |
Bridge and crossing structures functioning as choke points during storms, trapping debris and restricting flow capacity. Developer legally responsible for ditch maintenance but maintenance funds locked in probate after Taogoshi's 2024 death.
Scope: Ditch clearing ~11,000–12,000 LF, remove/modify 2–3 obstructive bridge crossings, road grading (2,000–3,000 ft x 20 ft).
Key issues: Unpermitted bridge bottlenecking canal drainage. Dole/Castle & Cooke holds irrigation easements with maintenance responsibility.
4. Old Mill —
High
| Acres | 43 |
| Operators | 14 owners (CPR) |
| Structure | CPR subdivision, AG-1 zoning |
| TMK | 66025010 |
Debris embedded in soil must be removed for land to be safely farmable. Drainage systems and culverts need restoration. Proximity to two intersecting rivers creates recurrence risk.
Scope: Embedded debris remediation ~5–10 ac, compost amendments (100–150 CY/ac), deep ripping, culvert clearing.
Key issues: Broad soil/mud removal high-cost with limited benefit — targeted approach preferred.
5. Ranch 1 —
Moderate-High
| Acres | 62 |
| Operators | 43 lots / 16 owners |
| Structure | Subdivided ag lots |
| Owner | Savio Ranch 1 LLC |
| TMK | 67002037 |
| Ditch LF | 1,375 (GIS) / 5,249 (SOW) |
Drainage and roadway damage impairing operations. Access bridge along Farrington Highway removed during ditch clearing — replacement needed for dual access safety in this high fire risk region.
Scope: Ditch clearing ~5,249 LF (including behind Ranch Camp housing), bridge replacement (1), gravel fill (1.5 mi x 2 ft x 1 ft deep).
Key issues: Conservation-focused water management plan needed to address recurring erosion and gravel loss.
6. Kawaihāpai —
Moderate-High
| Acres | 186 |
| Operators | 58 CPR units |
| Structure | CPR subdivision |
| TMK | 68003009 |
| Ditch LF | 11,318 (GIS) / 11,154 (SOW) |
Blocked culverts, failing bridge crossings, roadway erosion, and ditch systems with significant sediment and vegetation buildup.
Scope: Ditch clearing ~11,154 LF, culvert restoration (quantity TBD), bridge/crossing condition assessment.
Key issues: Access roads and drainage crossings vulnerable to continued failure during future storms.
7. Kaʻena Farm Lots —
Moderate-High
| Acres | 185 |
| Operators | 28 lots |
| Structure | Subdivided ag lots |
| TMK | 68002005 |
| Ditch LF | 8,505 (GIS) / 9,842 (SOW) |
Roadway erosion, blocked culverts, reduced drainage performance. Ditch systems partially obstructed by sediment, vegetation, and storm debris.
Scope: Ditch clearing ~9,842 LF, culvert restoration, drainage improvements at recurring washout locations.
Key issues: Impacts are preventative — recurring erosion and drainage deficiencies threaten long-term access and resilience.
8. Lovan Farm —
Moderate
| Acres | 59 |
| Operators | 1 operator |
| Structure | Single operator lease |
| TMK | 66024001 |
Primary need is removal and disposal of C&D debris from storm impacts. Recovery straightforward once debris cleared.
Scope: Surface debris removal, hauling/disposal, staging coordination.
Other Impacted Areas
Kahuku Ag Park —
Assessment · ~420 ac
Multiple farm operators · Road leveling + debris removal
~280 ac Ag Park + ~140 ac Zipline area (Neva estimate). Every farm needs road leveling and debris removal. Gravel needed for farm access roads. Ag Park encompasses ~30 individual farm lots (5–12 ac each).
Scope: Road leveling, debris removal, gravel for farm access roads. Full assessment needed.
Key issues: Large-scale ag area outside current NS scope. Multiple operators on individual lots within larger Campbell Estate parcels.
ʻIliʻili (Waiʻanae) —
Critical · ~8 ac
Multiple family farms · Severe flooding + home damage
Multiple farm properties along ʻIliʻili Road experienced severe flooding. Family homes and agricultural areas sustained flood damage including structural collapse. Properties remained flooded for weeks causing extensive damage and unsafe conditions. Mud/silt/clay deposits blocking drainage flow.
Scope: Debris removal (mud/silt/clay, 1–3 loads), excavator work, drainage restoration. Multiple individual property assessments needed.
Key issues: Combined residential and agricultural impacts. Families living on farm properties with damaged homes. Worsening flood risk from blocked flow. Navy drain outfall at Paʻakea Road causing erosion across multiple farm properties with large kiawe trees falling from softened ground.
