Overview
Havelock R-20/R-15/R-10/R-8/R-6A use minimum-lot-size-in-thousands as the naming index (R-20 = 20,000 sf). Commercial districts use B-1/B-2/CBD/O-I. AICUZ overlay (§154.07) is effectively city-wide because Havelock surrounds MCAS Cherry Point. UDO lives in Chapters 150-159, not Chapter 20 (v2 brief had incorrect chapter reference). | naming_convention_raw=lot-size-index-residential ; sub_flags_raw=[aicuz-dominant, nc-160d, amlegal-403-blocked] ; narrative_ref=narratives/havelock-nc/c9bbd6b8-df50-47fa-96e0-04bb4ae4cf3d.json
- Havelock geographically surrounds MCAS Cherry Point; AICUZ overlay coverage is effectively city-wide, making §154.07 the dominant controlling regime on most parcels rather than a special-area overlay. — [§ 154.07]
- AICUZ APZ-I ∩ Noise Zone 1 or 2 caps residential density at 1 du / 5 ac (0.2 du/ac), overriding any base district's implied density in affected contours. — [§ 154.07 Table 154-4]
- AICUZ interaction rule: where a parcel is in both APZ and noise zone, the APZ use rule supersedes the noise zone's use rule. Most-restrictive-of-two governs. — [§ 154.07]

Overlays
Parcels within AICUZ contours published by MCAS Cherry Point, as mapped on the §154.01 official zoning map. Six subdistricts: Clear Zone, APZ-I, APZ-II, Noise Zone 1 (65-70 DNL), Noise Zone 2 (70-75 DNL), Noise Zone 3 (75+ DNL). Havelock physically surrounds MCAS Cherry Point so AICUZ coverage is effectively city-wide.

Quirks & notes
- Havelock geographically surrounds MCAS Cherry Point; AICUZ overlay coverage is effectively city-wide, making §154.07 the dominant controlling regime on most parcels rather than a special-area overlay. — [§ 154.07]
- AICUZ APZ-I ∩ Noise Zone 1 or 2 caps residential density at 1 du / 5 ac (0.2 du/ac), overriding any base district's implied density in affected contours. — [§ 154.07 Table 154-4]
- AICUZ interaction rule: where a parcel is in both APZ and noise zone, the APZ use rule supersedes the noise zone's use rule. Most-restrictive-of-two governs. — [§ 154.07]
- Recorded avigation easement / real-estate disclosure required for new residential construction within AICUZ contours. — [§ 154.07]
- NC § 160D-702 preempts design-element standards on 1-2 family detached dwellings. In Havelock the live exception hooks are NFIP (Ch. 156), AICUZ NLR acoustic standards, and voluntary Conditional Zoning (§154.05). — [NCGS § 160D-702; § 154.05]
- UDO is in Chapters 150-159 on amlegal (platform = American Legal Publishing), not municode. Scripted WebFetch returns 403 — browser retrieval required for Table 155-9 and Tables 154-3/4/5 cell values. — [amlegal platform behavior]
- Chapter 154 (zoning) and Chapter 155 (dimensional/use) split — v2 brief referenced 'Chapter 20' as UDO location; that was incorrect and has been corrected to Chapter 154 throughout. — [§ 154.01]
