What is the Purpose of the District?

Pursuant to an agreement with the City, the District was created to assist the City in providing water, sewer and drainage facilities, road improvements and police and fire protection to the property within the District. The existence of the District facilitates the City’s desire to have a development of equal or higher quality compared to developments within the City. The District will exist until the City annexes Trinity Falls into the City’s corporate boundaries.

The District will issue bonds to finance the construction of the water, sewer and drainage facilities, road improvements and fire protection improvements within the District.

The District is governed by a board of directors consisting of five property owners. These directors are responsible for the on-going business of the District and facilitating comparable City services to land within the District.
