Is there a programmatic function which has altered Puntarenas further than the geomorphological circumstances that formed it?

INTRODUCTION
INTRODUCTION
Puntarenas embodies a different type of industrial activity, one which consists of multiple smaller scale industrial sites, all lined up to form an industrial shore of scattered scenarios of the Puntarenas north coast. Even though small scale, their impact on the materiality of the coastline is imminent, causing a solidification of an otherwise maleable and ductile geomorphological behavior. This type of programmatic solidifcation has had a greater impact on the ecologies which interact with the urban development of Puntarenas. So strong is this solidified development that the border breaks with the urban process of Puntarenas.
Most of Costa Rica’s fishing income is obtained from the gulf of Nicoya’s fishing industry.
67% of the fishing produce is delivered and processed in Puntarenas’ northern industrial coastline
