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.


For example:

What is the importance of determining the relative importance of landscape features?


photograph description transect
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.
The overwash zone can be hazardous for structures, note the rocks for a revetment to hold the shore line.
Interpreting landscape values: scenic, natural or social.



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



2. The loss of structural integrity.


What are the systemic values of a tropical or subtropical shore?

Goals discussed:

“the ecological view”

“A Response to Values

p. 93.

“,,,we have been concerned to establish that natural phenomena are dynamic interacting processes, responsive to laws, and that these proffer opportunities and limitations to human use.”

p. 79.

The role of enforcement

The Valley’s --a case study in suburban growth--

N/NW environs of Baltimore, Maryland -- 1962-63
most intensive area of urban development pressure in the greater Baltimore MSA
“The problem then is to apply ecological planning principles and test them against the demands of metropolitan growth and the market mechanism.”


“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.”
p. 79.

$33.5 Billion potential in development values by 1980 = or pdv: prospective development value
p. 80.

“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.”
p. 81.

“The United States awaits a large-scale demonstration of a beautiful landscape developed with wisdom, skill and taste--the evolution of a process that can produce a noble and ennobling physical environment...”
p. 80

“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.”
p. 91.

Planned unit development (PUD) approach 1) increase density 2) spare vulnerable & scenic
20,000 towns (1) “Housing would be nucleated around
5000 villages (12) community facilities...”
500 hamlets (12)
p. 92.

“to develop land and preserve open space” as
“an expression of physical, social and economic goals.”
“It was also recommended that a Conservation Trust be created to receive gifts of land or money to purchase land for open space and that the Trust maintain such lands.”

“Sewer and highway policy can be used strategically to guide development...”

p. 93.

necessity of accumulated public powers (monitor and enforce) and a public - private partnership to exercise those powers “to exercise some measure of control over ...destiny”

p. 93.
