Organisation of implementation/ Envelopes
To organize and realize the implementation of a project over such a large area, the New Dutch Waterline is divided into seven sub-regions called “project envelopes”. These regions are called “envelopes”, because an envelope always has an addressee (the provinces) and some sort of content (the implementation program).
Envelopes contain the project plans and time-line for a unified region within the New Dutch Waterline, which are related to each other in terms of subject matter, implementation and development. They show coherence in a spatial sense, a procedural sense (for example for public–private collaborations and land development) and a financial sense (balance of profitable and non-profitable investments). In this way, the envelopes create the basic conditions for an integrated approach. This approach must take further shape in the implementation of the programme within each envelope. In theory, an envelope is addressed to the province or to the regional legislative framework of the Utrecht Regional Administration, or to a collaborative agreement between the sub-regions of the Line. The recipients are responsible for presenting themselves as the authority for the preservation and development of the Line. They direct further development of the projects, and mobilise partners for the development and implementation of the projects and envelope committees.
The seven envelopes are Vechtstreek North, Vechtstreek South, Kraag van Utrecht, Rijnauwen-Vechten, Linieland, Diefdijk and Loevestein.
