Courthouse Plaza

Project description

The project site consists of two parcels — 57 2 20 003 A and 57 2 20 004 D — totaling 10.34 acres in the City of Fairfax. The site is currently occupied by a single-story retail shopping center and two accessory, standalone retail buildings, together comprising approximately 91,850 square feet of retail space with surface parking. No residential units exist on the site at present.

The proposal, as described in the May 7, 2026 Master Development Plan and accompanying Statement of Support, would redevelop the site into a mixed-use project with 630 multifamily residential units in two phases (up to 315 units per phase), 74,059 square feet of ground-floor retail, and 980 total parking spaces. The buildings are proposed at up to 72 feet in height, consistent with the six-story intent of the applicable Small Area Plan. Approximately 6 percent of the residential units — approximately 38 units — are committed as affordable dwelling units. Residential tenure (for-sale versus rental) is not established in the project documents; the analysis defaults to rental assumptions for household size, occupancy, and the income premium. The project is currently under review by the City.

A note on document consistency: existing retail square footage is stated as 91,850 square feet in the Master Development Plan tabulation sheet, 91,860 square feet in the Transportation Impact Assessment, and approximately 92,000 square feet in the Statements of Support; figures are close but not identical across documents. The May 7, 2026 Master Development Plan governs for purposes of this analysis. Phase 1 open space is stated as 10.6 percent in the May 7, 2026 Master Development Plan, superseding the 20 percent figure in the March 3, 2026 version.

Economic effects

New demand

The project is projected to add 567–611 new households (central estimate: 598.5), derived by multiplying the 630 proposed units by an assumed stabilized occupancy rate (central value 0.95, range 0.90–0.97). Applying Rutgers CUPR residential demographic multipliers for multifamily unit types to those households yields a projected population of 850–1,344 new residents (central estimate: 1,077). The household size assumption (central value 1.8 persons per unit, range 1.5–2.2) reflects a typical studio/one-bedroom/two-bedroom product mix; this is the assumption to which the resident estimate is most sensitive. Because residential tenure is not confirmed in project documents, rental defaults are used throughout; for-sale product would raise the household-size, occupancy, and income-premium assumptions.

Aggregate annual household income for incoming residents is estimated by multiplying projected households by the mean income of the site's census tract (tract 51600300200, ACS 5-year 2024, source table B19025/B11001: $195,124) and applying a new-construction income premium (central value 1.125, range 1.0–1.25), reflecting that new-construction multifamily product tends to attract households above the area median. The resulting aggregate income range is $110,635,229–$149,050,238 per year.

Spending categories and cluster capture

New annual household spending is estimated by multiplying projected households by BLS Consumer Expenditure Survey 2023 category averages, scaled by income relative to the CES reference and by category-specific Engel elasticities. The five largest spending pools are: comparison retail ($4,156,959–$7,492,873/yr), grocery ($3,683,400–$5,938,361/yr), entertainment ($3,468,764–$6,393,495/yr), restaurants and bars ($3,295,232–$5,808,549/yr), and personal services ($952,098–$1,697,106/yr).

Where that spending lands is estimated using a Huff gravity model applied to individual retail points of interest, with a joint destination-and-mode choice. These are screening estimates — they rank likely destinations with sensitivity bounds and are not predictions. The top two retail clusters capturing projected new-resident spending are Fairchester Drive & Hill Street ($4,066,763–$7,156,667/yr, led by grocery and comparison retail) and Chain Bridge Road & North Street ($2,993,312–$6,761,492/yr, where entertainment and restaurant spending are prominent). More distant clusters — Fair Lakes Parkway & Fair Oaks Mall ($1,272,361–$1,914,364/yr, dominated by comparison retail) and Mathy Drive & Pickett Road ($1,062,429–$1,652,006/yr) — capture meaningfully less. The Huff model estimates that 61.5–69.4 percent of total retail spending (all categories) and 66.2–76.1 percent of restaurant-and-bar spending would land at destinations inside the city boundary.

Project's own retail capture

The project's 74,059 square feet of ground-floor retail competes in the Huff model as a destination. The model estimates the project's own retail would capture $380,848–$855,012 per year of the new residents' spending (central estimate: $643,946), with restaurants and bars as the largest category. This is also a screening estimate. Of that total, $114,126–$575,276/yr is estimated to arrive on foot (walk-mode share of the joint destination-and-mode choice at the on-site destination). Walk-in capture reflects only the new residents' spending under the model; it is not a total pedestrian commerce figure.

Foot-traffic index

The model estimates a 0.5 percent change in the foot-traffic index across the 10 nearest commercial street segments, computed by allocating exact marginal trip flows from the new residents (using POI-weighted destinations with exponential walk-decay and shortest-path routing) against a sampled baseline betweenness index of today's pedestrian population. This is a screening estimate. The percentage comparison uses a sampled index, not calibrated pedestrian counts; the figure is directional rather than precise. New annual spending arriving on foot across all destinations is estimated at $486,551–$9,546,881/yr (central estimate: $2,250,851/yr) — a wide range driven by the walk-share and decay-rate assumptions. Bike-arriving spending is estimated at $15,160–$1,502,995/yr (central estimate: $246,502/yr); the bike-mode analysis notes that cycling reaches approximately three to four times the spatial range of walking per minute of travel time.

Jobs ledger

Applying a square-feet-per-job assumption to the existing 91,850 square feet of commercial space yields an estimate of 183.7–367.4 jobs displaced from the site (central estimate: 262.4), using existing commercial sqft divided by an assumed sqft-per-office-job (central value 350 sqft/job, range 250–500). The proposed 74,059 square feet of retail space is projected to support 105.8–185.1 on-site retail jobs (central estimate: 148.1), derived from proposed retail sqft divided by an assumed sqft-per-retail-job (central value 500 sqft/job, range 400–700). The net on-site job change ranges from −261.6 to +1.4 jobs (central estimate: −114.3), reflecting that the new retail space is smaller than what is removed and carries a different density assumption. No office square footage is confirmed in the project documents; office jobs added is zero in the model.

Fiscal effects

Current and projected real estate tax

The two project parcels (57 2 20 003 A and 57 2 20 004 D) currently generate $202,072/yr in real estate tax, computed as the current assessed value multiplied by the City's real estate tax rate. Following redevelopment, the projected assessed value is estimated at $241,359,331–$318,751,051 (central estimate: $247,785,200), computed as 630 units multiplied by an assumed assessed value per unit plus 74,059 retail square feet multiplied by an assumed commercial value per square foot. The per-unit value assumption (central value $360,983/unit, range $359,599–$458,932/unit) is anchored to three City of Fairfax apartment-class comparable properties built since 2011 drawn from the City's assessment database. The commercial value-per-square-foot (central value $275/sqft, range $200–$400/sqft) is a screening range that should be refined with commercial comps in a follow-up analysis. No office square footage is confirmed; the office component contributes zero to projected assessed value.

Projected real estate tax on the redeveloped site is estimated at $2,588,579–$3,418,605/yr (central estimate: $2,657,496/yr), yielding a net real estate tax increase of $2,386,507–$3,216,533/yr (central estimate: $2,455,424/yr) after removing the current tax.

Other recurring revenue lines

• Personal property tax on resident vehicles (rough estimate): $210,754–$908,583/yr (central estimate: $484,474/yr), computed as new households multiplied by assumed vehicles per household (central value 1.4, range 1.0–1.8) multiplied by assumed average assessed vehicle value (central value $14,000, range $9,000–$20,000) multiplied by the City's personal property tax rate. No project-specific vehicle data exists; treat as order-of-magnitude.
• BPOL business license tax on project retail (rough estimate): $5,361–$43,791/yr (central estimate: $17,388/yr), computed as proposed retail sqft multiplied by assumed gross sales per square foot multiplied by the BPOL retail rate, multiplied by a net-new share (central value 0.30, range 0.15–0.50) that accounts for spending displaced from existing city businesses rather than newly created. The net-new share is one of the more consequential assumptions in this line.
• Business tangible property tax (rough estimate): $12,235–$45,880/yr (central estimate: $24,469/yr), computed as proposed commercial sqft multiplied by assumed equipment value per sqft multiplied by the City's business tangible property rate.
• Meals tax on captured in-city dining: $98,203–$199,012/yr (central estimate: $144,387/yr), computed from restaurant-and-bar spending multiplied by the in-city Huff capture share multiplied by the City meals tax rate.
• Meals tax on the project's own restaurants (rough estimate, net-new): $36,188–$689,715/yr (central estimate: $195,613/yr), using ground-floor sqft multiplied by assumed sales per sqft multiplied by an assumed restaurant share of retail space (central value 0.50, range 0.30–0.70), multiplied by the meals tax rate and the net-new share.
• Local sales tax share on captured in-city retail: $52,379–$101,018/yr (central estimate: $74,421/yr), computed from in-city captured retail spending multiplied by the local-option sales tax share under Va. Code § 58.1-605.
• Local sales tax on the project's own retail (rough estimate, net-new): $26,806–$218,957/yr (central estimate: $86,939/yr).

Service cost estimates

Service costs are estimated under a marginal framing: only services that scale with new residents are included, with school costs separated and driven by a student-generation estimate rather than the citywide per-capita average. The approach has two named components. The non-school service cost applies the citywide non-school per-capita cost ($5,254/resident, from FY2027 adopted budget) multiplied by a marginal cost factor (central value 0.35, range 0.25–0.55) to the projected new resident population. The school cost component applies the net local cost per pupil ($19,961, derived from the FY2027 FCPS tuition contract net of state education revenue) to the estimated number of K-12 students: 31.5–75.6 students (central estimate: 50.4), computed as 630 units multiplied by an assumed students-per-unit rate (central value 0.08, range 0.05–0.12). The school cost is estimated at $628,757–$1,509,016/yr (central estimate: $1,006,011/yr). Total service cost under the marginal framing is $1,745,855–$5,393,871/yr (central estimate: $2,986,999/yr).

The marginal framing understates costs if the project triggers a service-capacity expansion; the marginal cost factor's range is intended to carry that uncertainty but does not resolve it. An alternative full-average framing — applying the entire citywide per-capita cost rate — was not computed in this version.

Net annual fiscal impact

Under the marginal framing, the net annual fiscal impact (incremental recurring revenue minus scaled service cost) is estimated at −$2,565,438 to +$3,677,635/yr (central estimate: +$496,117/yr). The range spans both positive and negative territory, meaning the sign of the net impact is genuinely uncertain under this analysis. The dominant sources of uncertainty are the marginal cost factor, the student-generation rate (which drives the school-cost component at $19,961 net local cost per pupil), and the residential value-per-unit assumption. No external fiscal estimates from the applicant or City staff were submitted for comparison in this review cycle; a staff report was identified in the project directory but contained no figures that could be reported.

Not evaluated in this version

Several analyses are deferred and were not computed as part of this version of the report. Specifically, the bike-lane corridor effects, trail connectivity impacts, broader multimodal connectivity analysis, environmental impacts (including stormwater, heat island, and tree-canopy effects), and comparable-places analysis (benchmarking project outcomes against similar mixed-use redevelopments in peer jurisdictions) were not evaluated. These items would be addressed in subsequent analytical phases as additional data and scope are confirmed.
