Preparatory study for the urban development measure
Mainz is growing. With its location in the Rhine-Main region and as an important university, media and biotechnology location, the state capital of Mainz is one of the fastest growing cities in Germany. In the past decade alone, the population has grown by 18,000 inhabitants.
One consequence of this growth is the high demand for housing, which is leading to ever-increasing rents and purchase prices for real estate and land. With the implementation of large-scale residential construction projects, such as the customs and inland port, the Heiligkreuz district, and the GFZ barracks, the development of large-scale inner-city brownfield sites has been completed.
For the city's development after 2030, the focus should therefore be on the outskirts. As part of the outer potential assessment, longer-term residential construction potential in the outskirts was identified and examined for suitability.
The expert identified the more detailed study areas in Ebersheim North/South (o.M.) and Hechtsheim – South (o.M.) as priority areas for development.
In order to develop the aforementioned areas quickly, the legislator offers the instrument of urban development measures. The urban development measure pursuant to Section 165 of the German Building Code (BauGB) is an instrument of special urban planning law for the acquisition of building land on previously unused or revitalized areas. It serves the orderly mobilization of building land for residential buildings, workplaces, or public facilities.
The legislature places high demands on local authorities for the implementation of this measure. There must be an increased public interest in an increased need for housing, workplaces, or public facilities. The welfare of the general public must, among other things, require the implementation of the urban development measure. In order to review the technical, legal, and economic feasibility and examine alternatives, the legislator provides for a preliminary investigation as a first step. The process of an urban development measure is always structured in several stages as follows.
Contents, objectives and procedure of the preparatory studies
The aim of the measure for the areas in the urban area is to develop the land, which has (mainly) been used for agricultural purposes to date, for the first time in order to meet the long-term housing needs of the city of Mainz. In order to secure the land for future residential development and at the same time prevent speculative increases in land values, the conditions for enacting an urban development measure are to be examined.
The purpose of the preliminary investigation, which is required by law, is to examine whether the legal and technical requirements (in accordance with Section 165 (3) of the German Building Code (BauGB)) are met in order to decide on an urban development measure for the areas under investigation.
In addition to general target development, this also requires the parallel preparation of various expert reports for the investigation areas in order to be able to make binding statements about their suitability. The scope and intensity of the preliminary investigations must be based on the planning objectives and measures for the specific development area in question. In addition, an urban development framework plan will also be developed for the respective study area. Among other things, the urban development framework plan serves to review the urban development potential of the areas. The results of the expert reports and the urban development concept ideas are to be brought together in the process and regularly adjusted.
