Challenges and Measures for Peizerdiep

The Peizerdiep flows between the Sterrebosstuw and De Onlanden. The stream valley and the surrounding area are being redesigned to make the natural environment more resilient to future challenges. An initial design for the area has now been completed and is being further refined through additional studies.

What is the assignment

The Peizerdiep flows between the Oude Stuw in the Sterrebos and De Onlanden. The Peizerdiep is part of a broader stream valley system in the northernmost part of Drenthe, which flows from the Fochteloërveen to De Onlanden. In this area, Noorderzijlvest Water Authority the Province of Drenthe are working to develop a future-proof water system. As part of this effort, we are improving water quality in accordance with the Water Framework Directive (WFD), designing the water system to better withstand both extremely wet and extremely dry weather conditions, and contributing to the development of the Dutch Nature Network (NNN). The measures focus on: 

  • Retaining Water Longer
    We are enhancing the area’s “sponge effect” so that water is retained longer and can be released more slowly.  
     
  • Providing Extra Space for Water
    Water storage capacity is being increased. By creating extra space for water in the Peizerdiep, peak discharge can be better accommodated. 
     
  • Restoring Natural Stream Dynamics
    Where possible, natural stream dynamics are restored so that the stream can return to its natural form. flood embankments are also being flood embankments . Without flood embankments , the area behind flood embankment flood embankments flood flood embankment . This allows for a more gradual drainage of water and reduces the risk of flooding elsewhere. This also enhances biodiversity by creating an alternation of wet and dry zones. 
     
  • Enhancing the (cultural) landscape
    Old landscape structures are being restored, for example by reintroducing vegetation and forests. This enhances the recreational experience for hikers and cyclists, in part by creating clear sightlines.  
     

Project Area

Location

The project area extends from the Oude Stuw in the Sterrenbos near Roden to the bicycle bridge over the Peizerdiep near the Bommelier (north of Peize). 

The redevelopment will take place in stages, with the design for the entire stream valley being further developed in phases. In Phase 1, we will develop two sub-areas:

  • Weehorst (southern part)
  • Stenhorsten (northern part)

What is the approach?

Redevelopment of the project area 

A phased approach was chosen for the redevelopment of the project area. Within the boundaries of the Dutch Nature Network (NNN), a preliminary design was developed that consists of an initial phase and a long-term phase.

This approach makes it possible to work step by step toward the final development of the entire Peizerdiep stream valley, as outlined in the long-term design. 

First phase 

The first phase will begin with the Stenhorsten and Weehorst subareas. On the map, Stenhorsten is shown in the upper area outlined in red, and Weehorst in the lower area outlined in red. 
 

Long-term phase

This phase will be further elaborated.
