An AB 98 mistake can shrink a Rancho Cucamonga warehouse site plan before a buyer reaches closing.
At 12459 Arrow Route, west of Etiwanda Avenue, the public file describes 334,776 square feet proposed on 14.8 acres: APN 0229-131-24. [1]
The first number to investigate is a date.
Arrow Route has a paper trail
Rancho Cucamonga’s Planning Commission adopted Resolution 2025-028 on September 10, 2025. All five commissioners voted yes. [1]
Newcastle Partners’ proposal would replace a former steel-wire manufacturing property with a warehouse.
Its master plan includes departures from ordinary roadway, parking and landscaping standards. [1]
An empty rectangle on a broker’s flyer leaves those conditions out. Parcel geometry, access and approvals belong in the investment analysis.
CEQAnet received the environmental-review notice of preparation November 1, 2023—before the September 2024 cutoff now in the warehouse statute. [2]
That chronology does not settle a changed proposal’s legal status or prove construction is underway.
900 feet ≠ a blanket setback.
A proximity trigger in specified project categories.
Loading-bay setback for qualifying industrial-zoned projects of at least 250,000 sq ft.
Loading-bay setback in specified nonindustrial-land / rezoning categories.
Selected thresholds under Government Code §65098.1. Project category and exemptions control. This is not a parcel survey.
What 900 feet actually means
California’s operative rules reflect SB 415, the 2025 amendment to AB 98.
The California Air Resources Board identifies it as chaptered legislation and describes changes to the logistics-development definition. [3]
The industrial-zoned category covers qualifying new or expanded projects of at least 250,000 square feet.
A loading bay within 900 feet of a sensitive receptor triggers requirements.
The specified loading-bay setback is 300 feet, measured directly from the nearest receptor’s property line to the nearest bay opening. [4]
The 900-foot figure is a threshold for applying rules, not a universal no-build ring around every home.
Other categories carry a 500-foot loading-bay setback.
Within the statutory warehouse concentration region, the nonindustrial-land and rezoning category applies more broadly than a simple 900-foot test.
Rancho Cucamonga, Ontario and Fontana are explicitly within that region. [4][5]
Smaller industrial projects face separate requirements. Dropping below 250,000 square feet does not make the chapter disappear. [4]
The exemption is a document question
Section 65098.1.6 excludes developments whose local entitlement process began before September 30, 2024. It separately addresses earlier qualifying local approvals. [5]
Arrow Route’s 2023 record merits examination against those provisions. It is not an exemption certificate for any future building at that address. [2][5]
The acquisition file needs the original application, dated agency receipts, approval conditions and exact proposal being purchased.
“Entitled” leaves too much unanswered.
Price the usable plan
Suppose a redesign removes 10,000 rentable square feet. At an assumed $15 annually per square foot, that removes $150,000 in potential yearly gross rent.
That is before expenses or vacancy. These are illustrative inputs, not Arrow Route rents or a project forecast.
Put access changes, revised drawings and agency conditions into the schedule before promising a tenant a delivery date.
Acreage is the opening number. The dated record determines what it can become.
