The Sapphire Bay development — what's actually happening and when

Sapphire Bay is the most talked about development in Rowlett and probably the most confusing. Here is what is actually happening based on public records, city council meetings, and what you can see with your own eyes.

What Sapphire Bay is: A $1 billion mixed-use development on 117 acres on the north shore of Lake Ray Hubbard. The centerpiece is a crystal lagoon — a massive man-made swimming lagoon with treated water, sandy beaches, and resort-style amenities. Around it: hotels, restaurants, retail, residential condos, and a boardwalk along the lake.

What has been built so far:

• Infrastructure: Roads, utilities, and grading are in place for Phase 1.
• The Sapphire Bay Resort Hotel broke ground and the structure is visible from Bayside.
• The lagoon basin has been excavated. You can see the massive hole from the overlook road north of Bayside.
• Some retail pad sites are prepped.

What has NOT been built:

• The crystal lagoon is not filled or operational.
• No restaurants or retail are open.
• The residential condos are still in planning/permitting.
• The marina and boardwalk are not started.

Timeline (based on the most recent city council presentation, February 2026):

• Hotel completion: projected late 2026 / early 2027
• Lagoon operational: projected summer 2027 (pushed back from original 2025 target)
• First restaurant openings: projected 2027
• Full buildout: 2030+

The concerns:

• The project has been delayed multiple times. Original announcements in 2018 promised much faster timelines.
• The crystal lagoon technology company (Crystal Lagoons) has had mixed results at other U.S. developments.
• Traffic impact on Bayside Pkwy and the surrounding neighborhoods has not been fully addressed.
• The TIF (Tax Increment Financing) district means Rowlett is investing public money in the infrastructure with the expectation of future tax revenue.

The optimistic case: If it works, Rowlett becomes a destination. Lake Ray Hubbard gets a resort-quality amenity that nothing else in DFW offers. Property values in Bayside and Waterview increase further. Restaurant and retail options in Rowlett expand dramatically.

The cautious case: Delays continue, the lagoon underperforms, and Rowlett is left with a partially developed site and a TIF obligation.

I am cautiously optimistic. The infrastructure investment is real and the location is prime. But I would not make a buying decision based on Sapphire Bay promises until you can physically walk into a restaurant there.
