conceptualization

• Water (part )*: +uality criteria, source, capacity,

tidal issues

• -oil (part .*: te/ture, che'ical properties• 0egetation, cli'atic, other deter'inants

WH0 AD SITES ARE SELECTED ALL THE WRONG REASONS!

• "THE LAND PRICE WAS A BARGAIN!“

• "THE GOVERNMENT WUS JUS’ GIVIN’ IT AWAY!“

• "HEY IT WAS NEAR THE WATER!“

• “BUT THERE WERE OTHER FARMERS NEARBY“

• "NOBODY ELSE WANTED IT!"

CONCEPTUALIZE THE SITE&

WHAT CONSTITUTES A SITE

• A PIECE OF LAND? COAST? COUNTRY?

• A SPECIFIC PROFIT CENTER?

• A SPECIFIC PRODUCT?

• SOCIAL OR ENVIRONMENTAL MISSION?
