Maricopa — Overlay Districts
Overlay Districts under the Maricopa local zoning and planning code, with the controlling citations.
Last reviewed: July 6, 2026
Overview
Maricopa’s Title 17 Zoning Ordinance uses overlay/combining districts to layer special rules on top of the base zoning. Two overlays show up in the Special Districts chapter: the Airport Approach Height Combining district and the Petroleum Extraction Combining district. These do not replace the base zone; they add focused limits or allowances, while base-zone uses and the city’s general development standards still apply (§ 17.3.30; § 17.3.50; Official Zoning Map administration) .
Overlays in Maricopa generally “combine” with a base zone: the base allowed uses and standards still govern, but the overlay adds aviation-safety limits (H) or oil/gas rules and allowances (PE) that you must meet on top of the base district (§ 17.3.30; § 17.3.50) .
How the overlay system fits into Title 17
- The Special Districts chapter lists the Airport Approach Height Combining (H) and Petroleum Extraction (PE) Combining districts (§ 17.3.30; § 17.3.50) .
- Overlay boundaries are not printed in Title 17; they are shown on the official zoning maps kept by the Planning Department (Zoning Maps provision) .
- Where an overlay is mapped, you apply the overlay’s rules in addition to base-zone standards, land use designations, and any applicable design review conditions (§ 17.3.30; § 17.3.50) .
District-by-District Breakdown
Airport Approach Height Combining (H) District
- Purpose and where it applies
- Improves aviation and public safety by requiring land use compatibility review within designated airport influence areas, consistent with the Kern County Airport Land Use Compatibility Plan (§ 17.3.30.1) .
- Typical permitted uses
- Uses permitted are those of the base zone; conditional uses are those of the base zone. The H overlay itself does not add new uses—it adds safety/height controls (§ 17.3.30.2–3) .
- Key dimensional and safety standards
- Height: Structures and mature vegetation may not exceed limits under FAA FAR Part 77 or the overlay’s standards; uses may not cause glare, smoke, or electronic interference affecting aircraft (§ 17.3.30 Development Standards) .
- Heliports must follow FAA Advisory Circular 150/5390-1B; the California Airport Land Use Planning Handbook principles apply (§ 17.3.30 Development Standards) .
- Lot size, setbacks, and all other base dimensional standards remain per the base district (§ 17.3.30.5–7) .
- Practical notes
- Expect your project to be checked for airspace penetration, potential glare, or electronic interference; the City ties the review to the countywide airport compatibility plan (§ 17.3.30) .
- If you need relief from height or siting because of airspace, you would pursue variances and exceptions through Title 17; relief is not guaranteed and must meet findings outside the overlay itself (variance provisions) . Verify with the jurisdiction.
Petroleum Extraction Combining (PE) District
- Purpose and where it applies
- Combines with a base zone to regulate oil and gas exploration/production in concert with the City’s Oil and Gas Production chapter; it does not replace the base zone (§ 17.3.50; Chapter 9 scope) .
- Typical permitted uses
- Oil and gas uses are identified as permitted in § 17.3.50.2; drilling is also “unrestricted” (no additional review) in specified districts or when allowed by § 17.3.50.2, subject to Chapter 9 requirements (§ 17.9.20; cross-reference to § 17.3.50.2) .
- If a well is within 300 feet of an existing dwelling or commercial building, those oil/gas uses require a conditional use permit under the PE overlay (§ 17.3.50.3) .
- Note: Within the Employment Districts uses table, oil and gas are listed as subject to Chapter 9, with a notation that when combined with a PE district, a CUP is not required in the HC zone; confirm per project since this interacts with base-district tables (Employment Districts Table 6.A note) .
- Key dimensional and operating standards
- Setbacks: No well may be drilled within 100 ft of an existing or proposed public right-of-way, official plan line, or specific plan line (§ 17.3.50.7.a) .
- Height: No height limit on derricks/equipment during exploration and drilling; pumping units limited to 35 ft (§ 17.3.50.8.a–b) .
- Minimum lot size, dwelling-unit area, yards, and other standards for non-oil facilities follow the base district (§ 17.3.50.5–7.b, 8.c) .
- Additional spacing and operational conditions come from the Oil and Gas Production chapter (§ 17.9.40; § 17.3.50.9) .
- Practical notes
- Chapter 9 includes “unrestricted drilling” in certain base districts and standards that still apply even when drilling is permitted by right; check the 100-ft ROW rule, noise/safety, signage limits for oil operations, and other conditions (§ 17.9.20; § 17.9.40) .
- Base-zone development items like parking, screening, and signage continue to apply to non-oil improvements unless Chapter 9 or conditions say otherwise (general Title 17 structure) .
Quick comparison table
| Overlay | What it changes | Key height rule | Key setback rule | Uses/CUP triggers | Code Reference |
|---|---|---|---|---|---|
| Airport Approach Height Combining — H | Adds aviation safety/compatibility limits to base-zone entitlements | Structures/vegetation must not exceed FAA FAR Part 77 surfaces; avoid glare, smoke, and interference | Same as base district | Uses mirror base zone; overlay adds safety/height checks | § 17.3.30; H development standards |
| Petroleum Extraction Combining — PE | Adds/clarifies oil and gas allowances and standards with Chapter 9 | No height limit on derricks during drilling; pumping units ≤ 35 ft | No well within 100 ft of any public ROW/plan line | Oil/gas near sensitive receptors (≤300 ft to a dwelling or commercial building) require a CUP; otherwise see § 17.3.50.2 and Chapter 9 | § 17.3.50.7–8; § 17.3.50.3; § 17.9.20 |
Related special districts you may see on maps
- The Drilling Island (DI) district is a standalone special district (not an overlay) used to concentrate oil/gas activity on a minimum 2.5-acre site with defined setbacks and height rules; it cross-references Chapter 9 for distances and operational standards (§ 17.3.40) . If you find DI mapped on your parcel, apply DI rules alongside base zoning and Chapter 9. For general planning context, see Maricopa Zoning.
Checklist
- Confirm your parcel’s base zone and whether an overlay (H or PE) is mapped on the official zoning map (Zoning Maps provision) .
- If in the H overlay, test building height against FAR Part 77 surfaces and confirm no glare/smoke/electronic interference; check consistency with the Kern County Airport Land Use Compatibility Plan (§ 17.3.30 development standards) .
- If in the PE overlay, determine drilling location relative to: (a) any dwelling/commercial building (300-ft CUP trigger), and (b) public ROW/plan lines (100-ft minimum); verify other Chapter 9 operating standards (§ 17.3.50.3, .7–.8; § 17.9.20, § 17.9.40) .
- Apply base-zone development standards for setbacks, height, lot size, landscaping and screening, and parking unless the overlay or Chapter 9 says otherwise (§ 17.3.30; § 17.3.50) .
- Determine if your project triggers design review or a CUP beyond the overlay (Title 17 permits framework) .
- For any uncertainty, pursue guidance or a variance via Variances and Exceptions (variance provisions) .
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Overlay boundaries | Overlays are not printed in Title 17 text | Confirm on the official zoning map before designing (Zoning Maps provision) |
| H overlay height calculations | FAR Part 77 surfaces and local topography affect allowable height | Provide elevations and profiles against runway centerline elevations (§ 17.3.30 development standards) |
| PE CUP trigger at 300 ft | Oil/gas near sensitive uses shift from by-right to CUP | Measure to nearest dwelling or commercial building; document proximity (§ 17.3.50.3) |
| PE setbacks to ROW | Wells must maintain 100 ft from ROW/plan lines | Confirm mapped ROWs, official plan lines, and any specific plan lines (§ 17.3.50.7.a) |
| Interaction with base-zone CUPs | Base-zone CUPs may still apply in addition to overlay | Check base-zone use tables and Title 17 CUP procedures (Title 17 structure) |
| Employment Districts nuance | Table note suggests CUP not required in HC when combined with PE | Confirm applicability to your parcel’s base district (Employment Districts Table 6.A) |
Plain-English Summary
If your Maricopa property sits in the airport approach overlay, your building height and materials can’t interfere with safe flight paths. If you’re in the petroleum extraction combining district, oil/gas activity is generally allowed but must meet strict spacing from streets, height rules for equipment, and may need a conditional use permit if close to homes or businesses—all while still meeting your base zone’s normal rules.

Frequently asked questions
Does the H overlay reduce my allowable height below what my base zone allows?
Yes, where the H overlay applies, structure and vegetation heights must clear FAA FAR Part 77 airspace and meet local compatibility standards, even if the base zone would otherwise allow a taller building. The overlay also prohibits glare, smoke, or electronic interference affecting aircraft (§ 17.3.30 development standards) .
Do oil wells always need a CUP in the PE overlay?
Not always. Oil/gas exploration and production identified in § 17.3.50.2 are allowed, but if a well is placed within 300 ft of any existing dwelling or commercial building, a conditional use permit is required (§ 17.3.50.3). Chapter 9 also controls operating standards (§ 17.9.20; § 17.9.40) .
How are setbacks handled for oil wells under the PE overlay?
No well may be drilled within 100 ft of any existing or proposed public right-of-way, Official Plan Line, or Specific Plan Line. Other development on the site follows base-zone setbacks (§ 17.3.50.7) .
Does the overlay replace my base zoning use list?
No. Both overlays “combine” with your base zone. The base permitted and conditional uses still apply; the overlay adds special limits (H) or special allowances/conditions (PE) (§ 17.3.30; § 17.3.50) .
Where can I find if my parcel is inside an overlay?
Overlay boundaries are on the City’s official zoning maps maintained by the Planning Department; they’re not printed in Title 17 text (Zoning Maps provision) .
If my project in the H overlay is just a rooftop solar array, do I still need to check height?
Yes. Any structure or appurtenance is subject to the airspace limits. Provide height data versus FAR Part 77 surfaces and confirm no glare issues affecting flight operations (§ 17.3.30 development standards). Verify with the jurisdiction .
Do the overlays change my parking or landscaping requirements?
Generally no—those continue to follow base-zone and citywide development standards, unless a permit condition or Chapter 9 standard specifically modifies them (§ 17.3.30; § 17.3.50) .
I’m in a commercial zone considering oil-related activity. Does the PE overlay change CUP needs?
It can. The Employment Districts uses table notes that combining with PE may remove the CUP requirement in the HC zone for oil/gas, but you must confirm applicability to your exact parcel and still satisfy Chapter 9 (§ 17.9.20; Employment Districts Table 6.A) .
