The Round Rock City Council approved a coordinated set of actions to enable development of roughly 230 acres east of County Road 110 and south of Westinghouse Road, including ETJ expansion, annexation, a future land‑use map amendment, SF‑3 zoning and council consent to creation of Round Rock Municipal Utility District No. 3.

The package begins with accepting 76.66 acres into the city’s extraterritorial jurisdiction to permit contiguous annexation of the larger Briggs tract. The council then approved municipal services agreements and annexed a 2.673‑acre Nelson tract strip needed to create contiguity. The council adopted a future land use map amendment designating the new area residential and rezoned the 230.08‑acre Briggs tract to SF‑3 (Single‑Family Mixed Lot) to accommodate single‑family development.

Developer presentations said the project will be built in phases over approximately a decade, with about 900 single‑family homes proposed on 50‑, 60‑ and 70‑foot lots. Builder Bill Peckman of New Home Company described the product as “move‑up” housing and estimated pricing “easily into the half millions,” noting that exact product and price will evolve over the phased buildout.

As part of the package, the council consented to the creation of Round Rock Municipal Utility District No. 3, an in‑city MUD that will finance infrastructure (water, sewer, drainage and roads) and levy taxes on MUD residents to repay bonds issued for construction. City staff said the MUD would fall under the city’s CCN for water and wastewater after coordination with the regional water supplier and the state.

Councilmembers pressed staff and the developer about traffic and future street connections, including planned right‑of‑way for Kenny Fort Boulevard (Segment 7) and stubs to adjacent properties to enable future links. Staff said standard development review will require drainage analysis, detention and mitigation of off‑site impacts, and that roadway and utility impact fees apply.

A consent and development agreement sets phasing, standard reviews and developer obligations; council also asked staff to work with the developer and regional utilities to transfer the water service area to Round Rock’s CCN for continuity. All related motions passed in roll‑call votes during the meeting.
