Participating in community design activities.
What is a charette?
It is a means of having any group of interested people collaborate in deciding what a place should look like, before any plans are finalized for the development or redevelopment of a specific terrain.
Steps to do before a charette.
Distinguishing values relative other uses.
Examples of competing values to resolve.
What is the importance of determining the relative importance of landscape features?

Here this over-wash zone bears the full exposure to radiation, wind and tides, in addition to currents from both the ocean and the bay. Both the size of the dunes and the extent of the vegetation on a dune are indicators of how fierce these forces are in redesigning the sand along the shore. | |

Dunes have value:
What sort of value?
Without a barrier dune system there are consequences:
1. The common loss of protective features,

| Can you see the weak areas? | Dune weakness causes a breech |
or
2. The loss of structural integrity.
What are the systemic values of a tropical or subtropical shore?

and limitations to human use.”

“The problem then is to apply ecological planning principles and test them
against the demands of metropolitan growth and the market mechanism.”
Setting
“Its 70 square miles -- almost 45,000 acres-- contain great sweeping valleys,
wooded ridges and plateaus, an intricate pattern of streams, farms, rural roads
and copses of trees. It is a beautiful inheritance, a serious responsibility,
an area threatened, a challenge and opportunity.”

“When this project was examined in terms of the development value produced,
it was seen to create an anticipated value of $7,000,000 in excess of the uncontrolled
growth model.”

“The problem is one of diverting development to the plateau, which is capable
of absorbing it, and deflecting it from the valleys where despoliation would
result.”
