Rocklin’s long-dormant Big Gun Quarry site is on track for a serious glow-up. City leaders and a California developer have rolled out plans for the Rocklin Public Market at 5255 Pacific St, a three-acre former quarry next to Quarry Park that could soon hold shops, a market hall, a brewery, a full-service restaurant, and around 20 homes stacked above street-level retail. City and developer materials pitch the project as a walkable downtown magnet for both locals and visitors.
What’s planned for the site
According to the City of Rocklin, the concept calls for a two-story retail building, a two-floor market hall with food and beverage vendors on the ground level and an open second-floor event and seating area, a three-story mixed-use building with 20 residential units over ground-floor commercial space, and a two-story brewery and restaurant with a covered outdoor patio. A new parking lot is also in the mix, designed to work in tandem with existing city-owned parking nearby. The property falls inside Rocklin’s Business Attraction, Retention, and Revitalization (BARRO) Overlay Zone, which is meant to boost activity in the area.
Who’s behind the proposal?
Developer G3 Concepts, the firm behind the San Luis Obispo Public Market, submitted a stack of applications in early October seeking design-review, conditional-use and environmental approvals, according to WhatNow. G3 Concepts operates the SLO Public Market and brings that market-hall playbook to Rocklin. Reporting notes the company filed a $21,000 design-review application on Oct. 9, 2025, and that specific tenants have not yet been named.
How it fits into Rocklin’s downtown plan
City staff say the Rocklin Public Market builds on years of work along Pacific Street and will land inside the Quarry Architectural District, potentially giving the city a new gathering spot that links Quarry Park with downtown businesses. The Big Gun property was cleared of old quarry structures in 2017, and the City Council approved the sale of the land to G3 in 2024, according to the City of Rocklin. The site also sits within the Business Attraction, Retention, and Revitalization overlay, which is designed to jump-start activity in Rocklin’s core.
Next steps
Early renderings went out ahead of an Architectural Review Committee meeting in early December that took a close look at the design and materials, with the committee tasked with weighing how well the proposal matches the character of the Quarry District. KCRA reported on the committee’s review and the city’s visuals. The developer and city officials have not yet released any tenant lineups or a construction schedule, according to WhatNow.
Why this matters
Supporters say a public market could open the door for smaller food and retail businesses that struggle to afford traditional storefronts, pump more evening activity into the Quarry Park area and send extra foot traffic toward existing downtown shops. Neighbors and planners, meanwhile, are expected to keep a close eye on parking, traffic and how well the new development meshes with the current streetscape as the project moves through the review process. Final approvals are still needed, and the design could evolve before any shovels hit the ground.
