The Crossing at Coal Mountain: Latest Update on This Cumming, GA Mixed-Use Development

The Crossing at Coal Mountain is a 140-acre mixed-use development taking shape in the Coal Mountain area of north Forsyth County, near Cumming, Georgia. The project will feature more than 700 residential units along with over 70,000 square feet of retail space and more than 20,000 square feet of office space. As of early August 2026, the development is under construction and being delivered in phases. The most recent verified milestone is Toll Brothers'  July 7, 2026 announcement that two new townhome collections, called Cottonwood and Haven, opened for sale at the community. The project's retail plaza remains under construction, with a summer 2026 completion target. For buyers and homeowners in north Forsyth County, this update matters because it shows how new housing supply and future commercial amenities are arriving in a part of the county where residential rezoning is currently restricted by a countywide moratorium.

What Is the Development?

The Crossing at Coal Mountain is a master-planned, mixed-use town center. <cite index="14-1">It includes more than 700 residential units, a mix of single-family homes, townhomes, and apartments, along with over 70,000 square feet of retail space and more than 20,000 square feet of office space</cite>. Atlantic Residential broke ground in July 2025 on the 47,000-square-foot Phase One retail plaza</cite>, which is being built by Fortune Johnson. The residential portion is being developed in partnership with Toll Brothers, a national homebuilder. Phase One construction has focused on the retail plaza and adjacent multifamily buildings, while Toll Brothers has separately opened single-family and townhome sections for home sales.

The retail component is designed around a food-and-beverage focus. About 60 percent of the retail space is planned for food and beverage vendors, while the remaining 40 percent is reserved for soft goods and services such as spas, salons, and fitness concepts, plus a roughly 20,000-square-foot pad site intended for a grocery or market anchor</cite>.

Where Is the Development Located?

The Crossing at Coal Mountain sits  in the Coal Mountain area of north Forsyth County, Georgia, roughly 50 miles north of downtown Atlanta</cite>, near GA 400. Toll Brothers' single-family section, Toll Brothers at The Crossing at Coal Mountain, is located at 3505 Settingdown Road in Cumming, while its newer townhome section is located at 4280 Waylon Drive, also in Cumming.  The community is assigned to Forsyth County Schools, including Coal Mountain Elementary and North Forsyth-area schools</cite>.

What Was Recently Announced or Decided?

The most recent verified project update is dated July 7, 2026. Toll Brothers announced the opening of two new townhome collections, Cottonwood and Haven, at The Crossing at Coal Mountain. This follows an earlier milestone on March 10, 2026, when. Toll Brothers announced the grand opening of its first two single-family home collections, Heartland and Magnolia, along with three model homes at the community</cite>.

On the commercial side, the most recent detailed construction update on record describes progress as of September 2025, when Atlantic Residential reported that framing on the flagship mixed-use retail building had reached its fifth level, two multifamily buildings were under construction, and key roads and infrastructure were being installed. No newer public construction milestone for the retail plaza itself has been confirmed at this time, so readers should treat the retail plaza's completion as pending rather than finished.

Separately, this development is unfolding against the backdrop of countywide zoning policy. On April 28, 2026, the Forsyth County Board of Commissioners extended its moratorium on residential rezoning through October 25, 2026, with exceptions for new rezoning applications to the RES1, MRD, or MCD zoning districts.

What Is the Development's Current Status?

The Crossing at Coal Mountain is under construction, with parts of the residential component already open and available for purchase. Home sales opening for individual collections does not mean the entire 140-acre project is complete. The retail plaza, office space, and remaining residential phases are still being built. The first phase of retail and housing construction was targeted for completion by summer 2026 but no source confirms that Phase One has fully wrapped up as of early August 2026. Buyers and homeowners should understand that an opened home collection reflects that specific builder section being ready for sale, not a confirmed opening of the surrounding retail plaza or office component.

What Does the Development Include?

Based on verified sources, planned and delivered components include:

• Single-family homes (Heartland and Magnolia Collections by Toll Brothers, open since March 2026)
• Townhomes (Cottonwood and Haven Collections by Toll Brothers, open since July 2026)
• Apartments (multifamily buildings under construction as part of Phase One)
• A 47,000-square-foot retail plaza with dining, shopping, and entertainment space
• A roughly 20,000-square-foot pad site targeted for a grocery or market anchor
• More than 20,000 square feet of planned office space
• Resort-style residential amenities, including a clubhouse, pool, pickleball courts, and a design studio for personalizing new homes</cite>

Who Is Developing the Project?

 Atlantic Residential is the developer of the mixed-use and retail components, with Fortune Johnson serving as the builder for that portion of the project JLL has been appointed to lead retail leasing and marketing for the development. The residential home-building portion is handled separately by Toll Brothers, Inc. (NYSE: TOL), which sells and markets its own single-family and townhome collections within the community.

What Is the Expected Timeline?

• Groundbreaking on Phase One retail plaza: July 2025
• Single-family home collections open (Heartland, Magnolia): March 10, 2026
• Retail Phase One targeted completion: Summer 2026 (estimate; not yet confirmed complete)
• Townhome collections open (Cottonwood, Haven): July 7, 2026

No official date has been publicly confirmed for a retail plaza grand opening, and no additional residential phases beyond the collections named above have been confirmed as complete. The timeline may shift as vertical construction and interior build-outs continue.

Are Road or Infrastructure Improvements Included?

 Phase One construction has included installation of key roads and supporting infrastructure within the development itself, tied directly to connecting the retail plaza, multifamily buildings, and residential sections. No separate, publicly funded off-site road-widening or intersection project has been confirmed in connection with this development at this time.

How Could the Development Relate to Local Real Estate?

The Crossing at Coal Mountain may be relevant to real estate decisions in north Forsyth County for a few reasons. New single-family and townhome inventory is currently available for sale directly from the builder, which gives buyers an active new-construction option in an area where the county's residential rezoning moratorium has limited new subdivision approvals. The planned retail plaza and office space, once complete, could add nearby dining, shopping, and service options for residents in the surrounding Coal Mountain area. No verified property-value impact has been reported for nearby existing homes, and approval or construction progress does not guarantee that every planned phase will be completed on the original schedule.

What Buyers Should Consider

• New single-family and townhome collections are currently open for sale directly through Toll Brothers.
• The surrounding retail plaza and office space are still under construction and not yet confirmed as open.
• Buyers interested in future walkability to shops and restaurants should ask builders and the developer for a current construction timeline before assuming amenities are available.
• Forsyth County's residential rezoning moratorium (through October 25, 2026, with limited exceptions) may affect how much additional new-home inventory is approved nearby in the near term.

What Sellers and Homeowners Should Consider

• Buyers researching nearby resale homes may ask about the status of retail and office construction at The Crossing at Coal Mountain.
• Homeowners near the site may want to monitor construction progress and any additional phases the developer announces.
• The distinction between an opened home collection and a completed retail plaza is worth clarifying for buyers unfamiliar with the project's phasing.

What Investors Should Monitor

• Confirmed construction milestones for the retail plaza and office space, since these remain incomplete.
• Additional builder or tenant announcements from Atlantic Residential, Fortune Johnson, JLL, or Toll Brothers.
• Any changes to the Forsyth County residential rezoning moratorium, which currently limits new rezoning outside RES1, MRD, and MCD districts.
• Confirmed retail tenant leases, since none of the sources reviewed name a signed retail or grocery tenant at this time.
