League City, TX Landscaping Rules: Tree Removal & Heritage Trees (2026)

All development in the League City floodplain requires a permit per Chapter 50 of the League City Code of Ordinances which was revised in January 2012. Development includes, but is not limited to, all new construction, filling, grading, and paving. Substantially damaged or improved structures, where the cost of repair (regardless of the cause of damage) or improvements to a structure equals or exceeds 50% of the building's market value, also require building permits and elevation certificates, and are held to the same standards as new construction. National Flood Insurance Program: Communities participating in the National Flood Insurance Program must regulate to minimum standards in order to provide subsidized flood insurance to their citizens. In some cases, the City of League City has chosen to go beyond the minimum standards in order to provide further protections to its citizens. One higher standard League City adheres to in its floodplain ordinance is the requirement of all new construction and substantially improved structures. New construction and substantial improvement of any residential structure permitted on or after October 1, 2018, shall have the lowest floor (including basement), elevated a minimum of 24 inches above the larger of the base flood elevation (BFE), the crown of the nearest street or the highest grade adjacent to the building and be a minimum of three inches above the nearest 500-year flood.
