Tuesday March 26, 2013 Day 3 Marker Wadden Charrette
Ryan Coates, Stephanie Erwin
For the second day of the Markerwadden design charrette, we were charged with becoming more spatial with our concept. It took several scale exercises, pacing out meters in the Nieuwland Museum, before we became aware of the immensity of 500 hectares. Once we wrapped our heads around the enormity, we deconstructed our previous dike design, a series of v-shaped structures, each about one kilometer in length.
Our initial design was based on the concept presented to us by Natuurmonumenten, a continuous armored dike, sheltering several islands from southwesterly winds and ravenous currents. Because of the extreme conditions on the Markermeer, we recognized the need for a more protective barrier, but believed there was an opportunity to explore the idea of a gradient in the dike typology. We broke the 8.5km structure in to several angular sections, alternative the directionality of the points.
Throughout the day, we kept referencing the vastness of the space, the seemly endless horizon- a truly unique quality in the Netherlands. The emptiness of the horizon, every so often punctuated with landmarks, became an informant of the directionality of our dike structures. Our realization was that ‘nature’ in the Markermeer is a cultural landscape. We further developed our concept: directional, angular dikes (pointing at the horizontal landmarks) with naturalized, silt-based, wetlands in the crooks of the infrastructure to act as a constant reference of culture in the landscape.

Moving from the progress we made during the previous days we spent our time transitioning our concepts into a more fully realized master plan for the Marker Wadden. With our general themes presented the following evening we took into consideration the feedback given to refine the project and solidify the various moves we were making. Our morning brought us through a process of exploring the general shape of the barrier dike and island formation. With this exploration we looked into possible means by which we could transition from the basic arc structure which is the cheapest option to something that is also cost effective yet allows for a more engrossing, dynamic landscape to form behind the dike.
Our ideas further developed around the concept of creating places for human interaction, with further zones limited to the creation of ecologically rich systems for the benefit of wildlife. As we moved further into the spacial planning we also began considering the underwater topography. We discussed how that might be used to create areas that are able to help with the deposition of silt while also working to manage the traffic patterns of leisure boaters moving through the Marker Wadden.
We laid down plans for phasing and development of various ecological zones while also beginning to tackle a more detailed design for the landing lagoon. Exploring the various element of the lagoon we discussed the programming and movement through the area as well as how one might perceive the space as they arrive from across the water.
We still need to refine the various elements to have them read in a manner that expresses the concepts in a more cohesive manner. The workings of those pieces are there but more exploration will need to be done to refine the elements and make sure the reasoning for making certain moves is justified. What options can we propose to create the unique experience of the Marker Wadden yet allow for the design to remain cost effective to construct? Tomorrow we connect all the dots and begin producing for our Friday presentation with Natuurmonumenten and the stakeholders involved.

Our third charrette day in Lelystad was exciting and built upon the previous two days. We felt that our design had a strong foundation – based upon the principle of ecology and allowing visitors to explore and interact with some facets of habitat while allowing for a majority of the MarkerWadden island to be designed as inaccessible. Today we dove into more specifics related to our design – how would the program elements such as kayaking and camping manifest themselves spatially upon the landscape, the construction and phasing of the project over time, and determining more exact measurements for how large the island system should be.
We started our day be exploring the possibility of creating more separate habitat types within different landscape compartments – adding or subtracting the amount of silt input could increase the amount of water in a certain area and in turn create a diverse ecology. In addition, we also examined how creating sand barriers for the future islands would allow silt to be captured at an effective rate yet still remain cost-effective. Through a series of axon diagrams and section elevations, we explored how different land types would appear and be constructed over time. We received good feedback during our critique on possibly reducing the amount of walking paths on the main visitor island to accentuate the importance of nature as well as limiting human access to portions of the design. We are both looking forward to tomorrow when we can detail more of our spaces and head back to Utrecht to begin final production mode for our presentation to stakeholders on Friday.

Today, with speed and alacrity, we went further into the design details of our site, determining phasing (construction, ecology) programming and scaling. Our group tackled scaling first, developing a better understanding of space in the Marker Wadden because the site we are designing for is 1000 hectares, with approximately 500 of it in land. Ultimately, the whole of the Marker Wadden will be 10,000 ha, a considerable amount of delta spread out along the Houtribdijk.
We pushed further with the idea of ecology constructed, working towards a design for a structure that could hold silt in place and at the same time form an ecology and waypoints for people and researchers on the site. Our entry point for ferries and water craft, and the general public exploring the site began to take shape, as did an access program.
Where we left off was in seeking clarity for the constructed design—how it fits in the landscape and what its shape is. Or, what its shapes are. Jan Wouter and Roel gave us their thoughts about the weather considerations that these structures would need, including extreme conditions, directions of wave action and scour, and the fact that some of our land might come and go with storms. So, to think, sleep, and subconsciously think some more!
