Roseville — Overlay Districts

Q: What can a Development Standard (**/DS**) overlay change?

A /DS overlay can change specified development standards such as minimum lot size , setbacks , maximum coverage , maximum height , and parking ratios . Any changes must be listed in the adopting ordinance; standards not listed remain under the underlying zone (§ 19.18.020.B–E ) .

Q: If my property is in a Special Area (**/SA**) overlay, which rules control — the base zone or the Specific Plan?

If a parcel is zoned /SA , the applicable Specific Plan or rezoning ordinance controls; it may supersede the underlying zone’s permitted uses and development standards. If the Specific Plan or ordinance doesn't address a standard, the underlying zone standard applies (§ 19.18.030.B–C ) .

Q: Do flood overlays (**/FW** / **/FF**) prevent building on my lot?

Not necessarily, but /FW and /FF impose restrictions and flood-protection requirements. Some hazardous uses are restricted or prohibited and structures may need elevation/floodproofing and flood-encroachment permits. Verify where the parcel sits relative to the City’s “Official Floodplain Maps” (§ 19.18.040 , § 19.04.020(4–5) ) .

Overview

This page explains how Roseville’s zoning ordinance defines and uses overlay and special-purpose districts (the overlays that sit on top of base zones). It summarizes the purpose, where they apply, what they can change, and the practical steps applicants must follow under the local code. For city-wide context, see the Roseville zoning & planning overview and the city’s adopted Roseville Zoning map and rules. § references below are to the Roseville Municipal Code (Title 19 — Zoning) and are cited for every rule noted.

Key overlays covered

/DS (Development Standard) overlay — allows targeted changes to development standards (§ 19.18.020) .
/SA (Special Area) overlay — ties zoning to a Specific Plan or rezoning ordinance and can modify permitted uses and standards (§ 19.18.030) .
/FW (Floodway) and /FF (Floodway Fringe) — flood-safety overlays with use restrictions and permit triggers (§ 19.18.040) .
PD (Planned Development) — special-purpose district that creates parcel-specific uses and standards adopted by ordinance (§ 19.18.050) .
Corridor-specific special area districts (Atlantic, Douglas‑Harding, Douglas‑Sunrise) — implemented via Chapter 19.33 and applied as special area overlays with custom use tables and standards (§ 19.33.010–030) .

District-by-district breakdown

Note: before proposing changes, confirm the parcel’s official map designation (Zoning Map) and any specific plan references under § 19.06.020 and related map rules (§ 19.04.020) . You will frequently need design review and other site approvals described in Roseville Development Standards and design review procedures.

Development Standard overlay — /DS

Purpose: The /DS overlay is an overlay district that allows the City Council to modify discrete development standards of the underlying zone when reclassifying property (§ 19.18.020). .
What it can change: The Council may modify minimum lot size, minimum lot width, maximum lot depth, minimum yard setbacks, maximum coverage, minimum usable open space, maximum building height, principal building types, minimum landscaping setbacks, and minimum parking ratios. Any modification must be explicitly stated in the adopting ordinance; if not specified, the underlying zone controls (§ 19.18.020.B–E) .
Typical permitted uses: Uses are those of the underlying zone; the DS does not generally alter the list of permitted uses unless the adopting ordinance says otherwise (§ 19.18.020.B) .
Where it applies / map label: Designated on the Zoning Map by the symbol /DS after the base zone and the ordinance number that adopted it (§ 19.18.020.E) .
Practical guidance: When you see /DS, expect to find an ordinance or map note that lists the exact deviations from the base zone. If a specific plan applies, DS adjustments can also be provided via a residential subdivision Design Review Permit (DRRS) for certain standards (§ 19.18.020.C) — check the specific plan language and concurrent DRRS requirements; see Roseville Design Review and Roseville Development Standards for process details.

Special Area overlay — /SA

Purpose: The /SA overlay allows the City to modify both permitted uses and development standards by reference to an adopted Specific Plan or the reclassifying ordinance (§ 19.18.030.A–B) .
What it can change: The /SA may delete or add permitted/conditional uses, convert conditional uses to permitted uses (or vice versa), and set development standards that supersede the underlying zone; if a standard is omitted in the SA, the base zone standard applies (§ 19.18.030.B–C) .
Typical permitted uses: Determined by the referenced Specific Plan or rezoning ordinance — the overlay adopts a custom set of permitted/conditional/administrative uses tied to that plan (§ 19.18.030.B) .
Where it applies / map label: Designated on the Zoning Map as /SA plus ordinance number, or where part of a Specific Plan the overlay uses a plan abbreviation (for example, -SE for Southeast Roseville Specific Plan) (§ 19.18.030.D) .
Practical guidance: For parcels in an /SA, always read the Specific Plan document (or the rezone ordinance) because it overrides many base-zone development standards. Projects in these areas frequently follow different entitlement steps — check the applicable Specific Plan (examples and boundaries are given in Chapter 19.33 for certain corridors) and confirm design review requirements.

Floodway — /FW and Floodway Fringe — /FF

Purpose: /FW and /FF protect public health and property by restricting hazardous uses and requiring flood protection measures; the ordinance identifies flood areas along Dry, Linda, Cirby, and Antelope Creeks (§ 19.18.040 and § 19.04.020 notes) .
What they control: Uses dangerous in flood events can be restricted or prohibited, and uses vulnerable to flooding must be protected at time of construction. The overlay also governs floodproofing, storage of hazardous materials, floor elevations, and records maintenance; violations are subject to codes and potential permits (including flood encroachment permits) (§ 19.18.040 subsections) .
Typical permitted uses: Limited and tied to public safety; many residential and commercial uses may be allowed only with specific protective measures or prohibitions (see the detailed subsections in § 19.18.040) .
Where it applies / map label: Shown on the Zoning Map as /FW or /FF tied to official “Official Floodplain Maps” maintained by Public Works; boundaries are explicitly identified by those maps (§ 19.04.020(4–5) and § 19.06.010(B)) .
Practical guidance: If your parcel is in /FW or /FF, expect flood-encroachment permitting, elevation or floodproofing requirements, and restrictions on hazardous storage. Confirm the precise overlay extent with the Public Works “Official Floodplain Maps” and expect additional conditions in project approvals.

Planned Development — PD

Purpose: PD is a special-purpose district applied by ordinance to allow flexible, parcel‑specific mixes of uses and development standards when the standard zone options are insufficient (§ 19.18.050.A) .
What it can change: A PD ordinance must list permitted uses (including which are principally permitted, conditionally permitted, or administrative) and must adopt the parcel-specific development standards (setbacks, heights, FAR, parking, landscaping, etc.) as part of the PD ordinance or accompanying materials (§ 19.18.050.C–D) .
Typical permitted uses: Any use the Council deems compatible with the plan and General Plan objectives — the PD is intentionally flexible but must be adopted by ordinance and tied to findings regarding compatibility and design (§ 19.18.050.C–E) .
Where it applies / map label: Shown on the Zoning Map as PD followed by the ordinance number that adopted it (§ 19.18.050.B) .
Practical guidance: Expect the PD to function like a parcel-specific code: read the PD ordinance and any exhibits for exact permitted uses and numeric standards. The PD process requires submittal of proposed standards and design materials with a zoning amendment application; findings of compatibility and General Plan consistency are required.

Corridor and Downtown special areas (examples of /SA in practice)

The Commercial Corridor Specific Plans (Atlantic Street, Douglas‑Harding, Douglas‑Sunrise) are implemented as special area overlays with custom use tables, parking and development standards, and special entitlement rules (§ 19.33.010–030) .
Downtown Specific Plan / Downtown Code is incorporated by reference and prevails where it conflicts with the general Title 19 — so Downtown parcels follow the Downtown Code standards and procedures (§ 19.31.030–040) .

Quick decision table — most relevant overlay rules

Overlay	What it does (decision relevance)	Typical numeric/administrative items to check	Code Reference
/DS	Allows targeted edits to development standards on rezoning	Which standards were changed (lot size, setbacks, height, parking ratios); look for ordinance text or map note	§ 19.18.020
/SA	Replaces/augments permitted uses and standards via Specific Plan or ordinance	Applicable Specific Plan document or ordinance; superseding development standards; use table	§ 19.18.030
/FW & /FF	Flood hazard controls; can prohibit dangerous uses	Flood encroachment permit triggers; elevation/floodproofing; hazardous materials restrictions	§ 19.18.040
PD	Parcel‑specific allowed uses and development standards adopted by ordinance	PD ordinance and exhibits (setbacks, FAR, parking, landscaping, sign rules)	§ 19.18.050
Corridor Specific Plans (Atlantic / Douglas‑Harding / Douglas‑Sunrise)	Special-area overlay with tailored use tables, parking and standards	Use tables, nonconforming rules, parking standards, entitlement variations	§ 19.33.010–030

Checklist — what an applicant must satisfy (common steps)

Confirm parcel’s base zone and overlay(s) on the City of Roseville Zoning Map (§ 19.06.020) .
If parcel is /SA, obtain and review the applicable Specific Plan or rezone ordinance (the SA supersedes base standards) (§ 19.18.030.C–D) .
If a /DS or PD applies, prepare written/measured proposed deviations (lot sizes, setbacks, height, parking ratios, etc.) and include them with the zoning amendment/PD application (§ 19.18.020.B, § 19.18.050.D) .
For projects in flood overlays, include flood-encroachment design and elevation/floodproofing details and apply for required flood permits (§ 19.18.040) .
Prepare any required design review submittals (including DRRS for residential subdivisions where applicable) and follow Roseville Design Review procedures and Roseville Development Standards; include parking studies per local parking rules (see Roseville Parking) (§ 19.18.020.C) .
Identify any possible nonconforming-use issues (Corridor Plans have special nonconforming rules) and check Chapter 19.24 and § 19.33.040 where relevant .
Verify whether accessory dwelling units are impacted by the overlay and follow Roseville ADUs and Chapter 19.60 for ADU standards where applicable (§ references in general development notes) .
Expect public hearing notices for reclassifications; the notice must state the DS modifications where applicable (§ 19.18.020.D) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Parcel-specific ordinance language	A DS, SA or PD’s deviations live in the adopting ordinance or Specific Plan and control local standards	Read the adopting ordinance/Specific Plan text tied to the overlay symbol on the Zoning Map; verify ordinance number on map (§ 19.18.020.E, § 19.18.030.D)
Missing standard in SA / Specific Plan	If a Specific Plan omits a standard, the base zone standard applies — this can create gaps for applicants	Confirm which items the Specific Plan addresses; anything not addressed defaults to the underlying zone (§ 19.18.030.C)
Flood-overlay boundary uncertainty	Flood overlay extents are tied to “Official Floodplain Maps”; boundary uncertainty changes permit needs	Confirm exact boundary with Public Works maps and staff; check § 19.04.020(4–5) and flood sections (§ 19.18.040)
Nonconforming use rules in Corridor Plans	Corridor Plans have special nonconforming-expansion rules that supersede Chapter 19.24	Read § 19.33.040 and any Corridor Plan use tables to see what expansion or reconstruction is allowed
Interpretations and ambiguous language	The Planning Manager may issue interpretations; these can be appealed but affect timelines and entitlements	Verify whether an official interpretation exists for the applicable § and, if needed, pursue administrative interpretation or appeal (§ 19.04.030)

Plain-English Summary

Roseville’s overlays (marked /DS, /SA, /FW, /FF, and PD) sit on top of a parcel’s base zoning and either tweak numeric development standards, replace the base zone’s uses/standards with a Specific Plan, or control flood-safety measures. Always read the specific ordinance or Specific Plan noted on the Zoning Map — that document tells you the exact rules that apply to your parcel (§ 19.18.020–050 and Chapters 19.31, 19.33) .

Frequently asked questions

What is an overlay district in Roseville and how is it shown on the map?

An overlay district in Roseville is a zoning layer that modifies or supplements the base zone’s rules for a parcel (examples: /DS, /SA, /FW, /FF, PD). Overlays are shown on the City’s Zoning Map appended to the base zone (for example, “R3/DS” or “GC/SA”) and usually include an ordinance number or Specific Plan reference (§ 19.06.010–020, § 19.18.020.E, § 19.18.030.D) .

What can a Development Standard (**/DS**) overlay change?

A /DS overlay can change specified development standards such as minimum lot size, setbacks, maximum coverage, maximum height, and parking ratios. Any changes must be listed in the adopting ordinance; standards not listed remain under the underlying zone (§ 19.18.020.B–E) .

If my property is in a Special Area (**/SA**) overlay, which rules control — the base zone or the Specific Plan?

If a parcel is zoned /SA, the applicable Specific Plan or rezoning ordinance controls; it may supersede the underlying zone’s permitted uses and development standards. If the Specific Plan or ordinance doesn't address a standard, the underlying zone standard applies (§ 19.18.030.B–C) .

Do flood overlays (**/FW** / **/FF**) prevent building on my lot?

Not necessarily, but /FW and /FF impose restrictions and flood-protection requirements. Some hazardous uses are restricted or prohibited and structures may need elevation/floodproofing and flood-encroachment permits. Verify where the parcel sits relative to the City’s “Official Floodplain Maps” (§ 19.18.040, § 19.04.020(4–5)) .

How does a Planned Development (PD) overlay differ from a normal base zone?

A PD is parcel-specific: the PD ordinance lists the allowed uses and adopts tailored development standards (setbacks, heights, parking, landscaping, signs) for that parcel. It is adopted by zoning amendment ordinance and will control over generic base-zone rules where it addresses an item (§ 19.18.050.C–D) .

Does an overlay affect ADU rules?

Overlays can affect how development standards are applied, but Roseville’s ADU provisions (Chapter 19.60) remain applicable; check the overlay text to see if it specifically modifies ADU standards. Where uncertain, follow Roseville ADUs guidance and confirm with Planning staff (§ references in general development notes) .

If a Specific Plan and Title 19 conflict, which controls?

Where a Specific Plan (adopted as an SA or by ordinance) controls provisions for that area, the Specific Plan or Downtown Code provisions prevail over general Title 19 rules for matters the plan addresses (see Downtown Code incorporation and conflicts language) (§ 19.31.030–040, § 19.18.030.C) .

Who interprets ambiguous overlay language?

The Planning Manager issues administrative interpretations of Title 19 provisions and these interpretations are appealable to the Planning Commission (§ 19.04.030) .
