House Bill 4059 amends existing laws to expand the Sunbridge Stewardship District to include areas of the City of Orlando, enhancing the governance and operational framework of the district. Key changes involve the inclusion of references to the City of Orlando and Orange County, the requirement for district governing board elections to involve officials from both counties, and the authorization for the levy and collection of non-ad valorem maintenance taxes in both counties. The bill also clarifies that the district will not have comprehensive planning or zoning powers and must align its operations with the comprehensive plans of both Osceola County and the City of Orlando. Additionally, it introduces new definitions and outlines the district's jurisdiction, ensuring compliance with existing agreements and local government authorities.

The bill further specifies the election procedures for the district's governing board, increasing the population thresholds for electing qualified electors from 10,000 to 12,475, and so forth, ultimately leading to a board composed entirely of elected members once the population reaches 47,000. It also allows the board to maintain offices in either Osceola or Orange County and engage in public services such as water management and waste collection. The bill emphasizes transparency in the assessment process for special assessments and outlines procedures for issuing general obligation bonds, ensuring collaboration with local governments while maintaining fiscal responsibility. Overall, HB 4059 aims to facilitate better land management and development planning in the newly expanded district while enhancing the operational framework and governance of the district.
