What Would Lancaster's Sierra Gateway Plan Change?

If you’re considering a property near Lancaster’s Metrolink area, the Sierra Gateway Neighborhood Plan could change the zoning rules that govern what may be built or expanded there. The proposal would replace the existing Mixed Use - Transit Oriented Development zoning with a specific plan covering about 323 acres.

This is general information and not legal advice. Before relying on a district name or development standard, confirm the property’s designation with the City of Lancaster Community Development Department.

Where would the Sierra Gateway plan apply?

The plan would apply to about 323 acres generally bounded by Avenue I, Division Street, Avenue J and Fern Avenue, with Sierra Highway bisecting the area.

The General Plan calls this area the Transit Village Planning Area and designates it Mixed Use. Its current zoning is Mixed Use - Transit Oriented Development, commonly shortened to MU-TOD.

Lancaster began preparing the Transit-Oriented Zones plan in 2013 and adopted it in 2015. Minor updates to its land-use table followed in 2020. According to the Planning Commission staff report, that plan placed a strong focus on design and architecture through what is commonly called a form-based code.

City staff described those rules as overly complicated for applicants and staff. The report says the plan has been a barrier to development, has seen limited use since adoption, and has produced little to no change in the area.

The replacement is called the Sierra Gateway Neighborhood Plan, or SGNP. Its formal case is Specific Plan No. 26-001, accompanied by General Plan Amendment No. 26-001, Zone Change No. 26-001 and Zone Text Amendment No. 26-001. The city is the applicant.

How would the zoning framework change?

The proposal would replace MU-TOD zoning with the Specific Plan designation and make the area subject to Lancaster’s rules for specific-plan zones.

The old plan included six zoning designations with rigid development standards. The staff report’s summary of the new plan identifies these districts:

• Neighborhood Low, for single-family homes, duplexes, triplexes and quadplexes
• Neighborhood Medium, for the same housing types plus apartments and limited retail and commercial uses
• Mixed-Use, for flexible combinations that could include standalone multifamily, standalone commercial or mixed-use buildings
• Corridor, for a mix of higher-density residential and commercial uses
• Public, for parks and recreational activities, including Jayne Reynolds Park

The report does not identify which individual parcels would enter each district. Attachment A and the plan map contain parcel-level information, but they were not reviewed for this guide. Ask Planning or check the adopted plan map before treating a property’s proposed district as settled.

Insider also has a guide to the Lemon Grove Downtown Specific Plan.

What could be built in each district?

The permitted development would depend on the property’s assigned district and the detailed standards in the final plan.

The staff report gives broad use categories, but it does not provide enough information for this guide to state a property’s allowed height, density per acre, parking requirement, setback or other project standard. Those details should be checked against the plan itself and confirmed with Planning.

Where the Sierra Gateway Neighborhood Plan is silent, development would still have to comply with the Lancaster Municipal Code. The staff report says this would typically apply to development standards omitted from the specific plan.

All development in the plan area would be required to use 360-degree architecture.

The proposal would also amend Title 17. MU-TOD would be removed from Chapter 17.10, Mixed Use Zones, specifically Section 17.10.030.D. The area would instead fall under Article VII, Specific Plan Zone.

What would redevelopment trigger on an existing site?

Redevelopment or expansion could bring added site-improvement and security requirements under the proposed plan.

The Planning Commission staff report’s summary of Chapter 4 says all buildings being redeveloped or expanded, along with new ground-up development, would have to provide a security plan and on-site security features such as cameras and lighting.

The plan also uses a tiering approach for incremental improvements to already developed sites. The required work would depend on the level of redevelopment and could include security upgrades. Public outreach cited in the report identified interest in aesthetic improvements and more public amenities, including streetlights and landscaping.

The report does not say which improvements apply at each tier, exactly what activity triggers a tier, or what the work would cost. Those points would need to be checked in the plan and confirmed with Planning.

A separate Lancaster rule can still matter when a project includes landscaping. The Lancaster root-barrier and landscape ordinance guide covers that topic.

What happens to the drainage basin parcels?

The drainage basin parcels at the southwest corner of Division Street and Milling Street would be rezoned from Neighborhood Medium to Park under the proposal.

Those parcels are identified as Regional Housing Needs Assessment sites. The staff report says housing development there is unlikely because accommodating and rerouting the basin’s drainage would require high cost and engineering. The plan’s future vision is to use the area as open space.

According to the report, the Housing Element’s surplus sites in the plan area could accommodate 193 units. Rezoning the basin sites would remove an estimated 129 units.

Surplus sites on vacant lots would be zoned Mixed-Use, allowing housing development by right where the TOD Zones plan previously did not allow it. Staff concluded that there would be no net loss of Housing Element sites for the plan area.

The plan is tied to Housing Element Program H-5.2, which supports updating the TOD Zones plan around the Lancaster Boulevard core and Metrolink station. Lancaster adopted its 2021 to 2029 Housing Element in 2022, and the California Department of Housing and Community Development approved it on February 10, 2023. The city received Regional Early Action Planning Grants 2.0 funding through the Southern California Association of Governments in fall 2023 for the update.

Would current uses or projects be automatically changed?

Existing legal non-conforming uses would not be removed, and the plan itself would not approve construction.

The City Council staff report states both points directly. Any future development would be subject to separate approval. A new land-use designation establishes rules for future activity, but it does not mean a building, conversion or expansion has cleared city review.

Other property obligations also remain separate from this zoning proposal. Special tax or assessment questions require their own property review, as explained in the guide to Lancaster Mello-Roos districts and the Business Park assessment.

City staff found the zoning project statutorily exempt from environmental review under Public Resources Code Section 21080.085. The report describes that provision as applying to rezoning that carries out a housing-element schedule of actions approved by the state housing department.

The city sent consultation letters to 10 tribal representatives on March 9, 2026. Two respondents requested that future ground-disturbing development follow tribal consultation under the California Environmental Quality Act.

We spoke with a Lancaster owner who saw his neighborhood inside the proposed Sierra Gateway Plan area. He assumed the plan had already rezoned his property and approved nearby development. We separated the long-range proposal from the zoning and project approvals that would be needed before physical changes occurred.

What is the plan’s current status?

The available agenda records show scheduled City Council action, but they do not establish the final vote or effective date for this guide.

The Planning Commission staff report is dated July 20, 2026 and recommends approval to the City Council. The commission’s vote was not read.

As of November 6, 2026: the City Council hearing on the plan was on the August 25, 2026 agenda, and Ordinance No. 1155 was on the September 8, 2026 consent calendar for adoption. The minutes recording the votes were not read for this guide, so confirm adoption and the effective date with the City of Lancaster Community Development Department (Planning counter, (661) 723-6100, [email protected], printed on the city’s own Planning page).

The city’s Planning page said the Lancaster Municipal Code had been revised effective September 25, 2026, with online updates pending. It did not identify which ordinances that revision covered, so it should not be treated as confirmation that the Sierra Gateway ordinance took effect.

The short version

The Sierra Gateway Neighborhood Plan would replace Lancaster’s MU-TOD zoning across about 323 acres with a specific-plan framework.

For a buyer or investor, the practical questions are the property’s proposed district, the uses and development standards allowed there, and whether redevelopment would trigger incremental site or security upgrades.

Because the reviewed records do not establish the final vote or effective date, confirm the plan’s adoption, current code text and parcel map with Lancaster Planning before relying on the proposal.
