Overview

§ 01

Biscayne Subdivision is a family-friendly, exclusive, gated beach community located on the southwestern tip of the Bolivar Peninsula near Crystal Beach, Texas. This special getaway offers sweeping views of the Gulf of Mexico, with sunrise and sunset vistas from the wrap-around deck. The beaches in front of the subdivision are some of the widest on the Peninsula. Biscayne provides limited beach access through walkovers that can accommodate golf carts and foot traffic. If you’re ready to own your own piece of paradise, come explore this beautiful area and make plans for living the beach life!

MUD Disclosure (§49.452)

§ 03 · Data moat

● §49.452 Notice

Not in archive

This MUD is not yet in our §49.452 archive. We'll add it on request.

Texas Water Code §49.452 requires districts to publish annual notices with tax rate, bonded indebtedness, and assessed value. Most Harris-area MUDs publish these; a handful managed by Inframark do not.

Request this notice

● What this tells you

The §49.452 notice is the only public document that lists a MUD's exact tax rate, outstanding bond debt, and the assessed value used to compute your taxes — direct from the district, not the MLS. If the district is newer or has more bonds outstanding than its neighbors, your effective tax rate will be higher here than just across the street.
