Manteca — Overlay Districts

Last reviewed: July 2, 2026

Overview

Manteca’s overlay and combining zoning districts layer location-specific rules on top of the Base Zoning District to protect unique areas or implement special standards. The overlay framework, its map authority, and conflicts-with-base-zone rule appear in § 17.30.010 and § 17.20.020 of the Manteca Zoning Code; see the City Zoning Map for where overlays apply. § 17.30.010 establishes purpose and precedence, and § 17.20.020 explains when an overlay controls uses and standards . The Code currently calls out at least three overlay types: the Central Business District (CBD) (with CBD‑1 and CBD‑2), the Planned Development (PD) overlay, and the 200‑Year Floodplain (F‑200) overlay; each has distinct review rules and standards (see the Zoning Map and figures noted in the Code) .

NOTE: This page summarizes the overlay rules found in the Manteca Zoning Code. Where the Code defers to another adopted document (e.g., an adopted Planned Development or Specific Plan), the ordinance states that the adopted document controls (verify with the jurisdiction) .

How overlays interact with the base zone (quick rules)

• Overlays supplement or supersede the Base Zoning District when there is a conflict; when silent, the Base zone controls. See § 17.30.010(B) and § 17.20.020(B) for the controlling rule and that overlays are mapped on the Zoning Map .
• Overlays are shown on the official City Zoning Map and by map figure references in Chapter 17.30; check the map for parcel‑level applicability (Figure references are sometimes omitted in the document excerpts; verify map boundaries with Planning) .

District-by-district breakdown

Note: below each district name is bolded and the Manteca code sections that establish purpose/standards are cited. Always confirm the parcel’s zoning overlay on the official Zoning Map before relying on these summaries.

Central Business District Overlay — CBD (CBD‑1 and CBD‑2)

Purpose

• The Central Business District (CBD) overlay provides unique development and allowed‑use rules intended to preserve a pedestrian‑scaled, downtown character and to encourage a mix of uses downtown. See § 17.30.020 .

Typical permitted uses

• The Code supplies a granular permitted‑uses table (Table 17.30.020‑1) that replaces the underlying Base zone allowed‑use table within the CBD. The table uses the "A / C / M / N" shorthand (Allowed / Conditional Use Permit / Minor Use Permit / Not allowed), and covers residential (multi‑family, live‑work), retail, service, public assembly, parking/transit, and limited industrial/utility uses. See Table 17.30.020‑1 and § 17.30.020(C) for the full matrix .

Key dimensional & design standards

• Table 17.30.020‑2 sets the headline development standards for the CBD: maximum building height = 3 stories and 45 feet, maximum Floor Area Ratio = 1.0. The CBD explicitly ties minimum setbacks to the City's adopted building standards (setbacks: minimum required under the City's adopted Building Code) and contains special parking rules (see next bullet). See Table 17.30.020‑2 and § 17.30.020 .

Parking and frontage rules (decision‑relevant)

• Parking requirements default to Chapter 17.52 (Parking), except the CBD grants an explicit exemption for existing buildings: existing buildings re‑occupying or changing use are exempt from parking requirements; new construction is not allowed to place required parking between the building and the street. See § 17.30.020 (E) and Table references . Consult the City’s parking guidance for precise ratios and exemptions via the City parking page.

Where it applies

• The CBD Overlay Zones are mapped in Figure 17.30.020‑1 and are shown on the Zoning Map as CBD‑1 and CBD‑2 coupled to the base zone symbol; check the Zoning Map or the figure for CBD boundaries (Figure omitted in excerpt; verify with Planning) .

Practical guidance

• If your project is in CBD‑1 or CBD‑2, first consult Table 17.30.020‑1 to confirm whether your intended use is an "A", "C" or "M" use; then confirm whether the development intensity (height, FAR) fits Table 17.30.020‑2; if changing occupancy in an existing building, check the parking exemption in § 17.30.020(E) .

Planned Development Overlay — PD

Purpose

• The Planned Development (PD) overlay flags properties that require a site‑specific Planned Development document and process; PDs allow tailored allowed uses and development standards and are adopted by ordinance and referenced on the Zoning Map. See § 17.30.030(A–C) .

Typical permitted uses

• Allowed uses are those expressly listed in the adopted Planned Development document; a PD may refer to the underlying Base Zoning District uses or replace them. If there’s a conflict, the PD document controls. See § 17.30.030(D) .

Key standards and process

• Development standards, deviations, and exceptions are defined in the adopted PD. The PD process is legislative and requires City Council approval, public hearings, and findings. The Approving Authority may grant deviations from development standards (lot size, yard requirements, heights) if the PD application meets specific findings demonstrating superior design, open space, or public benefit (see § 17.30.030(E–F)). PDs may adopt unique standards that supersede this Title; where silent, the Base zone or City standards apply. See § 17.30.030(E–F) .

Where it applies

• PD overlay districts are mapped by symbol PD on the Zoning Map; the PD ordinance/document itself must be consulted for parcel‑level allowable uses and standards (PDs are "adopted by reference") .

Practical guidance

• For projects in a PD, acquire and rely on the adopted PD document referenced on the Zoning Map; if you propose deviations, prepare the findings under § 17.30.030(F) and expect City Council review and potential conditions of approval .

200‑Year Floodplain Overlay — F‑200

Purpose

• The 200‑Year Floodplain (F‑200) overlay designates areas subject to 200‑year flooding and imposes heightened findings and restrictions for new buildings and for increases in allowed occupancy. See § 17.30.040(B–C) .

What the Code requires

• The review authority must find one of four conditions to approve new development or entitlements that would create a new building or increase occupancy inside the F‑200: (1) State Plan of Flood Control or other facilities protect property to urban level of flood protection; (2) City conditions will protect property to urban level; (3) the local flood agency has made "adequate progress" toward flood protection; or (4) flooding exposure is three feet or less from a 200‑yr event from non‑local sources. See § 17.30.040(C) for the findings and § 17.30.040(D) for exceptions to allow portions of a parcel outside F‑200 to proceed while reserving entitlements for the portion inside F‑200 .

Practical guidance

• If a parcel sits wholly or partially in F‑200, expect discretionary review; the Code contemplates phased approvals and may withhold entitlements for the F‑200 portion until findings are met. Floodplain mapping and coordination with the local flood authority are essential; see § 17.30.040(C–D) .

Quick reference table — most decision‑relevant overlay rules

Checklist

• Confirm the parcel’s Base Zoning and Overlay(s) on the official City Zoning Map (Zoning Map is adopted by the City; see § 17.20.040) .
• If in CBD‑1/2, check Table 17.30.020‑1 for use permissions and Table 17.30.020‑2 for height (3 stories/45 ft) and FAR (1.0) limits (§ 17.30.020) .
• If proposing a PD rezoning, prepare a Planned Development application meeting the PD findings and public hearing requirements; expect Council approval and that the PD document will control (see § 17.30.030) .
• If any portion of the parcel is in F‑200, prepare flood‑related technical evidence and be ready to meet one of the findings in § 17.30.040(C); coordinate with local flood authority and check § 17.30.040(D) for phasing options .
• Confirm parking obligations: the CBD has special exemptions for existing building reuse and locational rules for new construction; consult Chapter 17.52 (Parking) for standards and § 17.30.020(E) for CBD exceptions — see the City parking page for guidance. Link to Parking page: Manteca Parking .
• Confirm which design review, signage, landscaping, or site‑planning chapters apply (the overlay may be silent and default to the City standard); consult Manteca Design Review, Manteca Signage, and Manteca Landscaping and Screening. If setbacks are tied to the Building Code, consult the California Building Standards Code.
• For ADU proposals in an overlay, check ADU allowances and whether the overlay adds constraints — consult Manteca ADUs and California ADU law link for state rules where needed.
• Verify anything parcel‑specific with the Community Development Department (staff determinations, map interpretation, and adopted PD or Specific Plan documents can change outcomes) — Verify with the jurisdiction.

Risks & Ambiguities

Plain‑English summary

Manteca’s overlays (notably CBD, PD, and F‑200) add place‑specific rules on top of a parcel’s base zone: CBD controls downtown uses and sets height/FAR and special parking rules; PDs are parcel‑specific planned documents that replace or modify base rules; and F‑200 restricts new buildings in mapped floodplains unless specific flood‑protection findings are met. Always confirm the overlay shown on the official Zoning Map and review the specific overlay tables and PD or specific‑plan documents; for parcel‑level uncertainty, verify with Planning. See § 17.30.010, § 17.30.020, § 17.30.030, § 17.30.040 for the controlling provisions .
