Overview

Overlay districts in Firebaugh are special-purpose layers that modify or add rules on top of the base zoning districts to address locational features, historic character, hazards or special design objectives. The Firebaugh ordinance explicitly lists the Planned Development (PD) overlay as the City’s overlay tool and prescribes how it combines with base zones and how it appears on the Official Zoning Map. See § 25-9.4 for the overlay concept and mapping rules.

Note: this page stays strictly within the Firebaugh zoning ordinance (Chapter 25) and summarizes what the code requires for overlays — for building-code technical requirements see the California Building Standards Code.

How Firebaugh overlays work (short primer)

  • An overlay does not replace the base zone; it is combined with it (for example R-1 (PD) or C-2 (PD)) and the underlying uses and standards remain unless the PD explicitly modifies them. § 25-9.4 and § 25-39.2.
  • Overlay district boundaries and suffixing conventions must be shown on the City’s Official Zoning Map. § 25-9.5.
  • The Firebaugh PD overlay is the City’s only enumerated overlay in Chapter 25; other overlay types (e.g., historic or flood overlays) are not listed in the retrieved materials. § 25-9.4.

District-by-district breakdown

Below is a focused, ordinance-grounded breakdown for the overlay(s) that Firebaugh’s zoning ordinance actually defines.

PD (Planned Development) — Purpose and where it applies

  • Purpose: The PD overlay promotes flexible, comprehensive development solutions that can respond to local planning priorities (air quality, preservation of farmland, housing affordability, traffic, aesthetics and livability). § 25-39.1.
  • Applicability: The PD overlay “can be combined with any single-family, multifamily, commercial or industrial district” identified in the ordinance; on the Zoning Map the PD is shown as a suffix to the base zone (example: R-1 (PD)). § 25-39.2 and § 25-9.4.
  • Where on the map: Official Zoning Map rules and amendment procedures apply; the Planning & Building Department keeps the map on file. § 25-9.5.

Permitted uses

  • Uses in a PD are the permitted uses of the underlying base zone unless the PD text or project application identifies modifications. § 25-39.3 and § 25-39.4.

Key dimensional and programmatic standards (what you can reasonably expect)

  • Minimum site area for planned residential developments: 15,000 square feet. § 25-39.7(a).
  • Common open space requirement: at least 10% of the gross area, excluding public streets. § 25-39.7(g).
  • Density flexibility: up to 25% increase in residential density may be requested if it furthers PD intent. § 25-39.7(c).
  • Lot size, street width, and yard setback reductions may be requested with findings showing they further the PD intent and meet safety standards. § 25-39.7(d–f).
  • PD projects must comply with applicable design guidelines for the underlying zone; site-specific design details are reviewed with site plan and design review. See § 25-39.7(b) and the City’s design review requirements referenced via § 25-53.

Practical note about permitted accessory uses

  • Because uses come from the base zone, accessory uses such as Accessory Dwelling Units (ADUs) are allowed only to the extent the underlying zone allows them and are subject to the ADU rules in § 25-41.9. For ADU procedural and sizing rules, consult the Firebaugh ADU page and § 25-41.9.

Project process and required approvals

  • Establishing a PD overlay requires a zone change (ordinance) plus an approved development plan; a development plan must be submitted with a legal description, a site plan consistent with site plan and design review standards, elevations, utilities/infrastructure plan, open space plan, and other materials listed in the code. § 25-39.5 and § 25-39.6.
  • No construction is allowed in a PD until the development plan is approved and the zone change is completed. § 25-39.6.

Table — Decision-relevant PD standards and references

Standard / Item What it means in practice Code Reference
Minimum site area: 15,000 sq ft PD residential projects smaller than this will need a clear finding or be ineligible. § 25-39.7(a)
Common open space: 10% At least 10% of gross site (not counting public streets) must be improved as common open/recreation space. § 25-39.7(g)
Density bonus: up to 25% Up to 25% higher residential density may be allowed when supported by findings. § 25-39.7(c)
Setback / lot / street reductions Reductions can be requested but require findings showing they further PD intent and meet safety standards. § 25-39.7(d–f)
Uses = underlying zone Permitted and conditional uses follow the base zone unless the PD application alters them. § 25-39.3–39.4
Development plan + Zone change required before construction Must complete both design review/site plan approval and the legislative zone change process. § 25-39.6, § 25-49
Mapping & labeling PD overlays appear as a suffix to the base zone on the Official Zoning Map. § 25-9.4–9.5

Checklist

  • Submit a development plan and legal description consistent with § 25-39.5 (site plan, elevations, open space plan, utilities/infrastructure plan). § 25-39.5.
  • Prepare site plans that satisfy the City’s site plan and design review requirements referenced in § 25-53. § 25-39.5(c).
  • File a zoning ordinance amendment (zone change) application and pay required fees; follow the application content and noticing rules in § 25-49. § 25-49.2–49.4.
  • Demonstrate required findings for the PD (benefits equal/greater than underlying zone, suitability, consistency with General Plan, CEQA compliance). § 25-39.8(a–e).
  • If requesting flexibility (density, setbacks, lot size, street width), provide explicit justification tied to PD intent and safety standards. § 25-39.7(c–f).
  • Confirm permitted accessory uses (including ADUs) are consistent with the underlying zone and § 25-41.9. § 25-39.3; § 25-41.9.
  • Expect staff and Planning Commission review, public hearing notice and Council ordinance for the zone change (see § 25-49 and public hearing rules § 25-5). § 25-49.4; § 25-5.

When preparing materials also consult Firebaugh’s development standards, parking and landscaping requirements because PD approvals must work within those standards (or request explicit flexibility as allowed). Verify with the jurisdiction for parcel‑specific mapping or interpretations.

Risks & Ambiguities

Issue Why it matters What to verify
Underlying zone controls uses PD adopts the underlying zone’s permitted and conditional uses unless changed — a PD does not automatically create new uses. Confirm the base zone for your parcel and the specific permitted/conditional uses in that base zone. § 25-39.3–39.4.
“Flexibility” requests need findings Density, setback, lot size or street-width reductions require findings that the changes further PD intent and protect safety. Without these findings the request can be denied. Prepare findings tied to § 25-39.7 and check which findings Planning Commission/Council will require. § 25-39.7; § 25-39.8.
Official Zoning Map accuracy The PD overlay must be shown and suffixing conventions followed; map errors can create permit confusion. Confirm the Official Zoning Map for your parcel with Planning & Building. § 25-9.5.
CEQA and other approvals PD findings explicitly reference CEQA compliance; a project may need environmental review that delays approvals. Budget time and budget for potential environmental review. § 25-39.8(c).
ADU and accessory rules vs. PD flexibility ADUs are governed by separate ADU rules; PD flexibility doesn’t override state ADU law. Verify ADU treatment under § 25-41.9 and state ADU law. § 25-41.9.
Fee, notice, and hearing requirements Zone changes and PD establishment require public hearing notices and fees; failing to follow procedure can invalidate approvals. Follow § 25-49 application and notice rules. § 25-49.3–49.4.

If any item above is parcel‑specific or uncertain, state: Verify with the jurisdiction.

Plain-English Summary

Firebaugh uses the Planned Development (PD) overlay to allow flexible, project-level changes to lot sizes, setbacks, street widths and density when a fully documented development plan and a zone-change are approved; a PD always starts from the base zone’s permitted uses and must meet the PD findings. Key numeric requirements in the PD include a 15,000 sq ft minimum site area for residential PDs and 10% common open space, and any flexibility requested must be justified under the PD findings. § 25-39.1–39.8; § 25-9.4–9.5.

Frequently asked questions

What is the Planned Development (PD) overlay in Firebaugh?

The PD (Planned Development) overlay lets the City attach a project-level set of flexible standards to any base zone so developments can propose changes to density, lot size, setbacks and street widths while meeting design guidelines and required findings. See § 25-39.1–39.2.

How do I know if my parcel is in an overlay?

Overlay designations (including PD suffixing) must appear on Firebaugh’s Official Zoning Map, which is held by the Planning & Building Department; verify your parcel on that map. § 25-9.5.

What uses are allowed if my property becomes R-1 (PD) or C-2 (PD)?

Uses are the same as the underlying base zone unless the PD application specifies changes. In other words, a PD does not automatically create new uses — permitted and conditional uses follow the base zone lists. § 25-39.3–39.4.

What minimum site size and open-space rules apply in a PD?

For planned residential developments the ordinance requires a minimum site area of 15,000 square feet and at least 10% of the gross area (excluding public streets) be improved for common open/recreational space. § 25-39.7(a, g).

Can I get smaller lots or higher density through a PD?

Yes — the PD allows requesting a density increase up to 25%, and reductions in lot size, setbacks and street width may be requested if findings show they further the PD’s intent and comply with safety standards. All such adjustments require clear findings. § 25-39.7(c–f).

What plans and documents must I submit to create a PD?

A development plan is required with a legal description, boundary survey, comprehensive description of the underlying standards to be modified, a site plan consistent with § 25-53 (site plan & design review), elevations, open space/landscaping plan, infrastructure and utilities plan, and other items listed in § 25-39.5. § 25-39.5–39.6.

Do ADU rules change inside a PD?

Not automatically. ADU rules are governed by the ADU section (§ 25-41.9) and state law; a PD that is combined with a residential base zone must still follow those ADU requirements unless a PD explicitly and lawfully modifies them (and such a modification must comply with state law). § 25-39.3; § 25-41.9.

Does a PD approval replace site plan or design review?

No. A PD project still requires site plan and design review in accordance with § 25-53, and the development plan must be approved before building permits. See § 25-39.5–39.6.

What findings must the Planning Commission / City Council make to adopt a PD?

The findings require showing the area is suitable, the PD provides benefits/safeguards equal or greater than the underlying zone, property owners consent where applicable, and the project complies with CEQA and ordinance provisions. § 25-39.8(a–e).

If I want to change the zoning map to add a PD, what is the public hearing process?

Zone changes (including adding a PD) follow § 25-49: complete application and fee, Planning Director completeness review, Planning Commission public hearing within 45 days of a complete filing, and noticed mail/publication per § 25-49.4. § 25-49.2–49.4.
