The City of Cottonwood Shores and Bluffview Waters, LLC Rubicon Development, LLC executed a fully stated Development Agreement in 2026 covering roughly 19 acres for a planned unit development (PUD‑M) of multi‑unit condominium towers and detached villa units, with indoor and outdoor amenities. The agreement restates obligations from an initial 2025 agreement and details phased construction: Phase 1 with up to ~23 detached 3‑bedroom villas and ~98 tower condo units, and Phases 2–3 with the balance of 113 additional attached condo units, plus optional amenities like an outdoor pavilion, spa, infinity pool, pickleball and tennis courts, fitness center, café/bar, dog park, and hiking trails. The developer is responsible for extensive off‑ and on‑site infrastructure: a new TxDOT‑permitted access road from RM‑2147 built to city standards, full reconstruction of the Duchess Dell cul‑de‑sac, an emergency crash gate on Knights Row, fire hydrants and sprinklers, engineered drainage and detention meeting LCRA and City criteria, an engineered water booster station and holding tank, fencing, landscaping, wastewater chopper pumps, and on‑site property management.All design and construction costs, city legal/engineering review deposits, utility tap and LUE fees, signage, and dark‑sky compliant lighting are borne by the developer. This large multi‑year project opens opportunities for civil engineering, sitework, roadway and drainage contractors, water/wastewater system designers and suppliers, fire protection firms, landscape and fencing contractors, amenity and recreation builders, property management providers, and signage/lighting vendors as the developer moves from entitlement into design and construction.

City approvals for permits are conditional on Horseshoe Bay agreeing in writing to accept wastewater from the project; a potential PID or TIRZ incentive agreement may be negotiated separately. Developer must deposit at least 7500 with the City to cover legal, engineering, and administrative costs, with potential 5000 replenishments.
