Site context · Fullerton Town Center

Locate the redevelopment within the shopping center

Atlas Fullerton (also marketed as Atlas Condesa) is located at 229 East Orangethorpe Avenue, Fullerton, CA, northwest of South Lemon Street and Orangethorpe Avenue in Fullerton Town Center. Costco and AMC are nearby shopping-center landmarks [1, 4, 6].

Redevelopment within Fullerton Town Center North is up. The project occupies an L-shaped area west of Lemon Street. A substantial existing retail building lies across the internal access aisle to the west. Commercial sites and their parking occupy the frontage between the project and Orangethorpe Avenue. Their approximate relative proportions follow the city's 2021 site plan. Costco is farther north, outside the diagram. This is a simplified planning diagram, not a current aerial map or measured parcel survey.

The redevelopment is one part of the shopping center: substantial retail remains to its west, and frontage businesses and parking separate it from Orangethorpe Avenue. Costco is farther north, outside this diagram.

The western retail building and southern commercial sites are shown at approximate proportions drawn from the city’s 2021 site plan, so the redevelopment can be read within the larger shopping center. Gray buildings sit within lighter commercial-site and parking areas. This original diagram simplifies shapes and is not a current aerial map, measured survey, or final floor plan.

Built form · the 2021 proposal

How height and FAR reshape the plaza

The redevelopment changes both the use of the land and the scale of the buildings. The city’s inventory describes two one-story commercial buildings, restaurants, and surface parking on the project site. Replacing that setting with a five-story apartment community introduces a much taller, more continuous building presence within the shopping center.

Four measures of development intensity
Measure2021 proposalHow to interpret it
Floor area ratio (FAR)1.96Total floor area counted under the applicable planning definition ÷ project land area. A FAR of 1.96 means 1.96 SF of counted floor area per 1 SF of land, summed across floors.
Residential height5 stories; predominantly 65 feetThe study describes towers and other architectural features reaching approximately 85 feet. That is not the height of the entire building.
Parking structure6 storiesThe garage stacks parking vertically. Its level count is separate from the apartment building’s five stories; garage and residential floor-to-floor heights can differ.
Residential density73.6 homes per acre329 homes ÷ 4.47 acres. Density counts homes per unit of land; FAR counts floor area. Larger apartments can increase FAR without increasing the number of homes.

City Initial Study [1]: existing site and surrounding development, pp. 2-1–2-3; residential height, p. 3-1; parking structure, p. 3-2; reported FAR, pp. 4-74–4-75. These figures describe the 2021 proposal, not verified measurements of the completed buildings. The FAR is reported directly from the study; it is not reconstructed by adding the separately stated residential, retail, and garage areas.

Five stories does not mean a FAR of 5.0. Building coverage is the share of the site occupied by building footprints. As a simple hypothetical example, five identical floors each covering 40% of a site produce a FAR of 5 × 0.40 = 2.0, before any floor-area exclusions. Courtyards and other unbuilt areas affect this relationship. This example does not estimate the project’s actual coverage.

What changes in the plaza—and why it matters financially

The taller building raises the roofline above the former shops and brings a substantial residential population into a setting organized around retail and parking. The plan’s courtyards, stacked parking, and ground-floor retail reorganize how the site is used. From an investment perspective, more usable floor area can spread land cost across more income-producing space, while structured parking, elevators, circulation, and construction complexity add costs.

The comparison is local to the redevelopment site. The city also identified Aspect across Orangethorpe Avenue as an existing community of similar density and scale. The change is substantial within this part of the plaza, while fitting a broader corridor that already includes multifamily housing.

The 4.47-acre project area is approximately 4.5 acres and includes portions of multiple assessor parcels. A project boundary need not match a single tax parcel. The reported $21 million sale concerns the development site, not the entire shopping center [1, 5].

Start with the investment decision

What had to happen before construction could begin?

The project replaces commercial buildings and parking with a five-story apartment community and ground-floor retail. The residential building wraps a parking structure. Existing buildings are being replaced; this is a change in land use rather than the reuse of a store's interior.

Case PRJ2020-00004. The record identifies the original applicant and approvals; the interval before construction does not, by itself, establish a permitting delay. [1, 2, 3, 7]

2021 proposal versus later marketingThe initial study analyzes up to 6,500 SF of retail. The later broker listing markets 5,995 SF. Preserve each figure’s date and purpose [1, 6].
Residential mixThe study identifies studios, one-bedroom, and two-bedroom homes. The calculator’s counts and average sizes are independently chosen teaching assumptions, not a verified final unit schedule [1].
Affordable apartmentsThe initial study specifies 17 very-low-income homes. The final recorded agreement and current rent limits are not reviewed here [1].

2021 traffic analysis · replacement of active commercial uses

Fewer daily trips can coexist with busier peak hours

The city study compared the proposed development with businesses operating on the site when the study data were collected. It did not compare 329 apartments with an empty lot. The estimates use Institute of Transportation Engineers (ITE) trip-generation rates, applied to each land use.

Why the estimated daily total falls

Land useSize used in 2021 studyEstimated vehicle trips / day
Existing fast-casual restaurant6,000 SF × 315.17 trips / 1,000 SF1,891
Existing shopping-center space9,700 SF × 37.75 trips / 1,000 SF366
Existing uses removed15,700 SF of active commercial uses2,257
Proposed midrise apartments329 homes × 5.44 trips / home1,790
Proposed retail6,500 SF × 37.75 trips / 1,000 SF245
Proposed totalResidential plus a smaller retail component2,035

The removed restaurant accounts for about 84% of the old site’s estimated daily trips. Its customer turnover generates more daily trip ends in the model than all 329 proposed apartments. Replacing that use and reducing retail floor area produces the estimated 222-trip daily reduction (9.8%).

Why the peaks move in the opposite direction

PeriodExisting usesProposed projectChange
Morning peak hour22125+103
Evening peak hour122170+48
Entire day2,2572,035−222

Many residents leave during the morning commute, when most of the replaced retail uses are closed. In the evening, the old commercial uses already generated trips, so the increase is smaller. The composition and timing of trips change even as their daily sum declines.

These are site trip estimates, not a prediction that all nearby roads become less congested. A vehicle entry or exit counts as one trip end; a visit arriving and departing counts twice. Congestion depends on intersection capacity, turning movements, queues, signal timing, Costco and other shopping traffic, and growth elsewhere in the area.

The study applied no reductions for internal capture or pass-by trips to the proposed project. Internal capture means trips between uses within the development; pass-by trips are stops by vehicles already traveling on the adjacent road. Walkability or fewer separate shopping drives may be relevant in practice, but those mechanisms do not explain the reported reduction in this calculation.

The 2021 plan also included a signal at Lemon Street / Liberty Avenue, southbound right-turn lanes, and restrictions on movements at the project driveway. These proposed roadway changes affect how traffic is handled. Their completion has not been verified in this case.

Initial Study, September 2021, Tables 4-29–4-31, pp. 4-107–4-109 [1]; revised Final Response to Comments, November 2021, pp. 1-1–1-2 [12]. The old study modeled 6,500 SF of retail; the current brochure markets 5,995 SF. The figures above preserve the original study rather than silently updating its assumptions. Totals reflect the study’s rounding. Actual traffic outcomes require later observations.
