Los patrones de crecimiento acelerado y desordenado, los efectos de la post-industrialización y los desastres ‘naturales’ imponen importantes desafíos a las practicas normativas del diseño, de manera que es necesario un acercamiento que opere más allá de las soluciones rápidas o las soluciones locales. En este contexto Landscape Urbanism surge en Norte América y Europa como una nueva disciplina de diseño que responde a demandas específicas y potenciales de estas condiciones. ‘Landscape’ no es entendido como un arte escenográfico, de embellecimiento o para traer la naturaleza a la ciudad, sino más bien como un modelo de conecección y operaciones temporales, a través de las cuales el espacio urbano es concebido y comprometido: el espacio urbano es diagramado como un paisaje; una ecología compleja y precesual. Con este modelo lo urbano puede ser conectado con lo local, las escalas regionales y globales son entendidas en términos de su futura orientación y potencial de comportamiento, opuesto a las estrategias nostalgicas y de division social de lo ‘nuevos’ enclaves urbanistas. Landscape Urbanism es por definición una práctica interdisciplinaria. Dibuja sobre el legado del diseño del paisaje para hacer frente a las dinámicas del urbanismo contemporáneo, integra el conocimiento y las técnicas de la ingeniería ambiental, estrategias urbanas y ecología del paisaje, y emplea las ciencia de la complejidad y emergencia, las herramientas del diseño digital y el pensamiento de la ecología política. A través de estos significados el taller proyecta un nuevo material de intervenciones que operan dentro de un urbanismo concevido como social, material, ecológico y contínuamente modulado por fuerzas espaciales y temporales de las cuales se encuentra conectado.

indexing de la información Mediación entre paradigmas de organización tipicos y las condiciones locales. Análisis y lectura sensible de la estructura urbana de la ciudad y las condiciones existentes, mediante el mapeo y la diagramación. Busca el desarrollo de la capacidad de leer la información del sitio para despues descodificarla, sintetizarla y procesarla sistematicamente como modelos indexados. desarrollo de prototipos Desarrollo de modelos organizacionales que reflejen las intenciones estrategicas de intervención en diálogo con las condiciones y necesidades locales. Con base en el análisis crítico y a la investigación técnica pertinente, se desarrollarán modelos prototipicos, los cuales deben tener la capacidad de moldearse a las transformaciones contínuas a la que pueda ser expuesto. intervención y propuesta Se desarrollará un sistema de intervención del territorio a varias escalas y tiempos de implementación. Para esto se deben establecer parámetros de desarrollo e implementación del sistema que respondan al comportamiento del territorio, y a la temática que cada grupo decida desarrollar, de manera que signifique una respuesta directa a las condiciones determinadas en la zona de estudio.

1. Instrumentalización: Se estudian diferentes ciudades del mundo que tengan características de desarrollo expansivo e intensivo, con el propósito de desarrollar técnicas de representacción gráfica, de análisis y lectura del territorio, para el correcto indexing de la información. 2. Caso de Puntarenas: Estudio y análisis exahustivo de la ciudad de Puntarenas, donde se aplican las heramientas desarroladas en el ejercicio anterior, con el fin de entender el territorio y sus potencialidades para la implementación y adaptación de nuevos sistemas de desarrollo y organización del espacial. 3. Contextualización: Implementación de un sistema de intervención para la zona en estudio, para la cual se debe desarrollar una temática el cual debe tener consideraciones, sociales, económicas y ambientales.

Different behavior diagrams were made according to their performance, flows, and specific characteristics from each programme. This produces a different reaction on the space of the different streets. The aim of these diagrams is to create a route of water treatment along the site so that we can find the characteristics will dictate its performance. By doing this the response of the city will give the design.

Design Parameters The urban design is dictated by different parameters and performances in order to create a direct response form the site. In this diagram the population density determines the capacity of the different components, like the wetlands, the canal, softscapes and texture. The performance determines the behavior and design of the components. By introducing these parameters with the sites characteristics we ensure that the design will respond completely to the qualities of the site. W - Wetland T - Textura Piso C - Canal D - Dique

We took the population density index so that we could locate the different zones of analysis in a larger scale. These zones allow temporality to the intervention by placing the system in zones with a larger density (greater amount of waste water). The aim is to attack the most critical zones in the city first.

To obtain a route that connects the cityâ&#x20AC;&#x2122;s landmarks with a greater use of the dorsscapes, and that also worked with an optimum performance, we created a synthesis between the technical route and the urban route.

This guarantees the functionality of the route, as an urban connector and as water treatment system.

As part of the route an indexing is created of the different drosscapes with their context performance to identify its possible programme.

Route B STEP 01. First the drosscapes and the landmarks are located in the map by using different types of dots. Then they are connected along a path that joins the different landmarks we want to use. This gives us a larger number of drosscape that we can intervene along the possible route of the project. These spaces will behave as new landmarks that encourage people to travel along the project. STEP 02. As part as a growth of the route we analyzed the pedestrian and vehicular flows. The aim was to locate the major concentrations so that we could drive them into the city.

The phase one of the water treatment works as an internal individual system for each block, and consists of two stages. The first part is an individual anaerobic process for each house where the most part of the solids are remove from water. After this is done, the water from each septic tank pass to a subsuperficial wetland that is located at the center of the block, where the rest of the remaining solids will be remove from the water. One of the many advantages of this block system is that it guaranty that if one of the parts fail the rest of the blocks systems stay functioning.

The second phase of the system is external, and it takes place on the urban space. The water treated from the sub-superficial wetland pass to a superficial wetland. After this the water is collected through a swale system that is going to bring it to the estuary. This water could also be used in some human activities such as loan irrigation, car wash, and aquaculture, among others.

The above diagram shows, in blue, interaction points of the city that work as attractors and bring dynamism to it, however, their programme is monotonous which means that the use of this areas has a short temporality that is well define by hours, as a result this attractors function isolated and independently from each other. The red areas correspond to a high concentration of abandoned estate or in other cases programmes that work like tumors of the city. The south sector of the territory has a touristic/commercial programme with strong influence to the beach, causing civil appropriation towards the natural territory, turning into a positive impact.

On the contrary, the north sector has a industrial development as well as a high concentration of abandoned estate that exclude the estuary from other city activities, functioning as a barrier between natural and artificial systems, as a consequence people have distanced themselves from it, turning their backs both physically and emotionally, causing degradation to this site. There are two limits clearly define, one that runs along the axis of the main road fragmenting the city activities and unable the dynamics from north to south, and a second one on the north of the city periphery, where industrial activities take place.

In the site the estuary is the area that presents a greater amount of contaminants, most of them come from the cityâ&#x20AC;&#x2122;s served water, only 30% of these waters receive some type of treatment before been thrown directly to the estuary. Other contaminants come from the agriculture located north of the estuary, were the rivers carry their chemicals, pesticides and fertilizers. Most of the sediments deposited in Puntarenas come from the Barranca river, nevertheless this process stopped to affect its geomorphology. This is because most of the sediments are carried at a depth between the 4m and 6m, and when they reach the point of Puntarenas the currents drag them to a pit of 45m of depth, located 3 kilometres southeast from the point of Puntarenas.

The cause that has promote this economy is the constant interaction between the population and the sea due to the closeness that they have with this resource. The Population of the zone has decreased, information that evidences the necessity to reconsider the way in which the productive activities have been focused, to guarantee the permanence of the population and an eventual increase. Puntarenas split may be consider independently of the rest of the territory of the province of Puntarenas because of certain characteristic as its connectivity, geomorphology and the difference that presents the industry with one of the rest of the province. We conceptualize Puntarenas Spit as a space were programmatic relations develop which are fragmented into three principal layers of intervention. The analysis of the split as layers inside the city of Puntarenas will provide an approach to the elements that influence the dynamics of the zone in either a positive or negative way, finalizing in a knowledge of the places were interventions take place and a more accurate understanding of the cityâ&#x20AC;&#x2122;s behaviour.

progtamatic layers

Layer 1

: the disconnection between the coastline and the waterscape. Offers a great opportunity to intervene because of its working commerce program.

Layer 2 : this layer is com-

pletely disconnected from the coastline program. Because of its individualism program Fail the task to retain foreign users.

Layer 3

: this layer itâ&#x20AC;&#x2122;s the interface between a industrial fishing program and a tourism program. It contains the main pedestrian and vehicular flow of Puntarenas city.

This layer is completely disconnected from the coastline program. Because of its individualism program Fail the task to retain foreign users, also there's no visual contact with the coastline and no pedestrian roads to insinuate a proper connection between activities.

We conceptualize Puntarenas Spit as a space were programmatic relations develop which are fragmented into three principal layers of intervention. The analysis of the split as layers inside the city of Puntarenas will provide an approach to the elements that influence the dynamics of the zone in either a positive or negative way, finalizing in a knowledge of the places were interventions take place and a more accurate understanding of the cityâ&#x20AC;&#x2122;s behaviour. The pattern visualized in the analysis, strengths the tourism sector activities, which is the principal source of income of the population and for that reason it will be our model to design.

The north coastline main deficiency to develop our urban proposal is that the tourism sector ,which characterizes Puntarenas economy, has been overshadowed by the worn-out fishing program of the zone.

The south coastline is based on a tourism and commerce economy , that generates a urban pattern which strengths the city Â´s economy . The above reasons propelled us to base our model on this pattern.

Z1:

this zone was selected because of the opportunity intervene and consolidate the program character of hotel of this zone, and like that helped us with the retain foreign problematic.

Z2: this zone has a opportunity to implement a beach sports program to attract a urban day life. It contains programmatic voids and green space that can be intervene to consolidate a connection into the second programmatic layer.

Z3:

this zone has a opportunity to implement the pier of Puntarenas and like that add programmatic layers that can reactivate it as a tourist point or attractor. Also by its location it can bring an opportunity to connect to some front coastline voids that can obtain a programmatic character of INVESTIGATION AND SCIENCE TECHNOLOGY BUILDINGS. e intervene to consolidate a connection into the second programmatic layer.

Beach is the main urban activity of Puntarenas. But only work if the sequences of patterns are working together.

Vegetation is the major source of urban activity in Puntarenas, as generates the best comfort conditions, generating the largest urban agglomerations. Sidewalk in front of the beach provides a direct contact with the vegetation and a pedestrian circulation that generates activity to the commerce. Established front beach commerce in Puntarenas, generates a continues urban flow activity, but its useless infrastructure is not retaining the visitant Street structure dividing the city, but providing a dense circulation

This pattern of commerce ,street, vegetation, beach...its the main impulse for the tourism economy of Puntarenas. Because of this the repetition of this pattern in our project will generate a direct activation of the urban intervention and the economy of Puntarenas.

Landscape Urbanism

A geomorphologic analysis of historical maps and aerial photographs of Puntarenas reveals systematic growth of the spit over the past 137 years. The sand bar shows lateral growing, basically in the tip. The lateral growing rate of the Puntarenas spit for the period 1860-1945 (prior to human control) is 14 m per year. Largest agglomeration of sediments near the coast line, 300,000 m3 of sediments pass through this point in a year. The marine currents along with the influence of Barranca River drainage, generated a series of phenomena, where the current begins to have a directionality towards the Northwest (high tide) and southeast (low tide). Points of great intensity and speed (compression) as the Rio Barranca draining area and the west area of Puntarenas, give us a hint of areas where some morphological change can occur.

Based on the areas of interest in Puntarenas, 3 main segments were created in this specific location. Trough this interventions more shore perimeter would be created. Through the process of sedimentation this new land would be self-created naturally in a few years. Three main segments, each of a different distance and direction were tested. They were evaluated on the sediment configuration left behind Then modified so they would fit the requirements stipulated by each of the 3 areas of interest. Ricardo Sevilla Sergio Frugone

GEOMORPHOLOGIES MASTER PLAN STRATEGY

Landscape Urbanism

Zone B

Zone C

Zone A

Zone A has a series of hotels around the immediate layer on the coastline, therefore the proposal arises as an intervention to consolidate an area incorporating its complementary program. The project links to the primary circulation flow throughout a diagonal, which has as a starting point an urban park that articulates visually the coastline

Zone B possesses a series of sport activities in its surroundings, therefore the project intends to incorporate and consolidate this activity with several complementary programs. The intervention connects to the urban secondary circulation flow by a diagonal park and venue which projects visual contact to the coast.

Zone C possesses a series of sport activi-

ties in its surroundings, therefore the project intends to incorporate and consolidate this activity with several complementary programs. The intervention connects to the urban secondary circulation flow by a diagonal park and venue which projects visual contact to the coast.

PHASE 2

PHASE 3

In the phase 1 the voronoi was made from the current infraestructural organisation marking at first the center of the blocks in red points by default the streets will appear. The need to have a geometrical guide to configure the proyect leed us to search for a more precise relational geometric field. To do that a subdivision of the previous voronoi was made leading to more red points in phase 2 and a smaller geomtric field as shown in the phase 3.
