Noah's Landscape Journal

Welcome to my MLA Blog This blog documents my weekly learning journey as part of the Master of Landscape Architecture (Year 1) at the University of Greenwich. It serves as a reflective space where I collect notes, thoughts, and visual material from the courses Landscape Design Technology and Design Experimentation & Communication. Each entry combines key aspects of the lectures with my own reflections, sketches, and examples from practice. The aim is not only to record what was taught, but also to explore how these ideas can be applied in design processes and future landscape projects.

Landscape Design Technology, 11/12/25, Permeable Modular Pavement

Permeable Modular Pavement, Steve Burton from Steintec

A first step for permeable surfaces in a project should be to think about how much water actually needs to run through the surface. Different requirements need different levels of drainage/permeability.

To ensure permeability, mortar joints need to be wide enough

Climate change factor:

Whaterver the Volume of Rainfall is, you add 40% to plan for the future and consider climate change.

Another key aspect of perm surfaces is pollution control:

Inflitration rate:

Total surface area : area of joints x permeability rate

-> how much water goes through 1m3 of the material

The infiltration rate gets lower after a few years. After 10-20 years it’s only about 10% of the original rate. So we should aim for a bigger infiltration rate that will last as long as possible.
