Planning & Design Approaches

In the interest of full disclosure, we want you to know that this part of the Impervious Surfaces website is composed of existing materials collected from the NEMO vaults. In the course of educating about natural resource based planning and “green” site design, the topic of reducing the amount and impacts of impervious surface comes up often. Here, then, we provide a convenience store from which to pop off to other items in NEMOland that are related to impervious surface, as well as links to a few key other resources.

There are a host of great articles on impervious cover and its impacts that were written for the defunct Watershed Protection Techniques journal, produced by the anything-BUT-defunct NEMO partner Center for Watershed Protection (CWP). These articles can be browsed (first page only) through the CWP-maintained Stormwater Center website at:

They are also compiled in the CWP publication, The Practice of Watershed Protection, which can be ordered through the CWP website at:

Design (with a touch of planning)

We have an entire section of the NEMO website devoted to alternatives to conventional impervious materials. It’s called Planning for Stormwater.

Design extends not only to individual parcels, but to entire developments and subdivisions. So try:
