The resolution to draw up the development plan pursuant to Section 2 (1) of the German Building Code (BauGB) is the start of the formal development plan procedure and is adopted by the Administrative Committee of the City of Salzgitter in accordance with the statutory provisions. The decision to draw up the plan is published in the Amtsblatt of the City of Salzgitter. The local announcement is supplemented by notices in the Salzgitter-Zeitung newspaper and on the City of Salzgitter's Internet portal.

The public, the authorities and other public interest bodies, such as utility providers or the Chamber of Agriculture, as well as affected neighboring communities must be informed as early as possible about the general objectives and purposes of the planning and its likely effects in accordance with Section 3 (1) and Section 4 (1) BauGB, whereby the authorities and other public interest bodies should also comment on the required scope and level of detail of the environmental assessment. While the authorities and other public agencies are generally involved in writing, the public is generally given two weeks to inspect the plans and to comment on and discuss them. The location and duration of the opportunity to inspect the plans will be announced in the usual manner.

On the basis of the plan concept and taking into account the comments submitted, the draft development plan with the plan drawing, the textual stipulations, the explanatory memorandum and the environmental report are prepared.

The public display in accordance with Section 3 (2) BauGB of the draft development plan, which is decided by the administrative committee of the City of Salzgitter, will take place for a period of one month at the town hall in Salzgitter-Lebenstedt. The decision to open the plan to the public is published in the usual local manner. The text of the announcement must make statements regarding the location and duration of the public display and indicate which types of environmental information are available. During the display period, comments on the development plan can be submitted by "anyone". At the same time, the authorities and other public agencies are involved again in accordance with Section 4 (2) BauGB, whereby their involvement can also be carried out before the public display.

If no significant changes or additions to the draft development plan are required as a result of the comments received, the development plan will be adopted by the Salzgitter City Council in a public meeting in accordance with Section 10 (1) BauGB after consideration of the comments received during the process. The development plan comes into force and is thus legally binding with the customary announcement of the resolution on the articles of association in accordance with Section 10 (3) BauGB. The development plan, together with the explanatory statement and the summary declaration, is available for inspection by anyone.
