Description

5 acres of commercially and industrially zoned land at the hard corner of Somerset Road and the I-35 frontage road, 8 miles south of downtown San Antonio. The property carries split zoning: C-3R along both road frontages (I-35 frontage road and Somerset), with the balance zoned I-1. The commercial strip supports c-store, gas station, QSR drive-through, and retail uses directly on the highest-visibility portions of the site. The I-1 interior adds outdoor storage, warehousing, and light industrial flexibility uncommon in a retail hard corner.

I-35 carries 53,000 vehicles per day past this site. A convenience/fuel operator (brand not disclosed) is under construction on the opposing corner across Somerset, validating the intersection for fuel and convenience retail. The adjacent Lennar Homes development to the north is complete — residential rooftops are in place and the trade area is established.

All utilities (water, sewer, electric) run adjacent to the site. No FEMA flood zone designation. Two on-site rental homes provide holding income during planning.

Covered Land Play
The majority of the parcel is raw dirt, development-ready. The two existing rental homes generate interim income during entitlement or site planning with no obligation to retain.

Assemblage Opportunity
The adjacent 0.54-acre western parcel (APN 1260854) is separately owned with an unlisted asking price. Owner is open to negotiating. Combined site would total approximately 5.54 acres, improving drive configuration, parking depth, or pad layout. Contact broker for details.

I-35 Corridor | South San Antonio Industrial & Retail Gateway
8719 Somerset Road sits at the convergence of two high-demand corridors: I-35 — the primary logistics artery connecting central Texas to the U.S.–Mexico border — and Somerset Road, the eastern gateway to South San Antonio's fastest-growing industrial zone.

Traffic & Access
I-35 daily traffic: 53,000 AADT (TXDOT). Somerset Road at the interchange: 3,655 AADT. Dual-direction access via the I-35 frontage road. The Somerset/I-35 interchange serves as the primary commercial entry point for the surrounding industrial and residential base — including the completed Lennar Homes community directly west and multiple industrial tenants along the Somerset corridor.

Institutional Demand Generators
Port San Antonio, one of the largest aerospace and defense campuses in the region, anchors the immediate area. Lackland Air Force Base lies to the southeast. St. Philip's College Southwest Campus and Texas A&M University – San Antonio (6.2 miles / 14 minutes) bring consistent workforce and consumer traffic. South Park Mall is 3.1 miles / 7 minutes.

Industrial Corridor Momentum
The South San Antonio industrial submarket totals 44.9M SF with a current vacancy rate of 9.5%. There is 1.4M SF under construction and over 16.7M SF in the proposed pipeline as of Q1 2026 (CoStar). Notably, a 2.8M SF logistics supersite — Frontera Logistics Supersite — is proposed at 8439 Somerset Road within the same corridor, with a projected March 2027 completion. This level of institutional development activity directly supports highway-facing retail and fuel demand along the Somerset corridor.

Retail Market Fundamentals
The South San Antonio retail submarket reports 3.0% overall vacancy as of Q1 2026 — near a 10-year low — with general retail vacancy even tighter at 1.3%. Market asking rents are $23.00/SF with positive net absorption. Retail rent growth in the submarket is forecast to continue through 2030 (CoStar, Q1 2026).

Surrounding Community
Established residential neighborhoods on both sides of the corridor include South Park, Gillette, Harlandale, Kingsborough Ridge, South Southwest, Hidden Cove, Indian Creek, United Southwest, Withers, Solana Ridge, and Valley Forrest — forming a dense, service-oriented consumer base with limited existing retail supply at this intersection.
