House Bill 4059 amends existing legislation to expand the Sunbridge Stewardship District to include areas of the City of Orlando and Orange County, revising the governance and operational framework of the district. Key changes include the requirement for district governing board elections to involve officials from both Osceola and Orange counties, as well as the necessity for general obligation bond elections to occur in both counties. The bill also introduces new definitions, such as "Orange County Territorial Agreements," and emphasizes that the district will not have comprehensive planning, zoning, or development permitting powers, ensuring compliance with the comprehensive plans of both Osceola County and the City of Orlando.

Additionally, the bill outlines specific legal descriptions for various parcels of land in Orange County, detailing their boundaries and measurements, while also addressing the qualifications and election of board members. It raises the population threshold for electing board members by qualified electors from 10,000 to 12,475, with a final threshold of 47,000. The bill further expands the district's powers to include infrastructure and environmental management responsibilities, mandates the submission of annual budgets to local governing bodies, and establishes procedures for issuing general obligation bonds and levying special assessments. Overall, HB 4059 aims to enhance local governance, promote sustainable development, and ensure equitable participation in the decision-making process.
