|dc.description.abstract||Costa Rica is well known for its ecological and landscape diversity. Nevertheless, most of its
cities have lost their natural richness due to uncontrolled growth in infrastructure. Urban
development has caused surface waterproofing, air and water pollution, poorer landscape
quality and a major loss of most native forests and the species living within them. This is the
case of the county of Montes de Oca, birthplace of the most important university in the
The main campus of the University of Costa Rica comprises nearly 87 hectares and has
conditioned urban growth in the area. It represents one of the few “green lungs” of the
Metropolitan Region and is constantly being threatened by the construction of new buildings.
This highlights the urgent need of an urban and landscape development plan. For this reason
we made a proposal for its protection, focused on natural continuity, cushioning, ecological
compensation and anticipation of future university expansion.
The landscape diagnosis analyzed water resources, slopes, runoff, flora and fauna. In 2017, the
effects of “El Niño”, caused prolonged droughts and heavy rainfall in short periods of time,
which resulted in flooding, high soil saturation and an increased risk of landslides. Green
cover in the county is made up of patches of secondary forests linked to the University and
Torres River, urban parks and isolated gardens. At “Finca 3”, the forest fragments represent at
least 26% of the land. A detailed survey of its flora allowed us to characterize trees by shape,
dimensions, color, as well as detecting the scarce, native, threatened species and the ones at
risk of extinction to define the conservation criteria. We identified 209 tree species on 34
hectares, surpassing the records of larger nearby protected areas famous for their biodiversity,
such as Cerros de La Carpintera (110 tree species in 2391 hectares).
At a regional level, we propose the integration of a green infrastructure network, through river
corridors and landscape connectors associated with the rivers, linking natural spaces.
Therefore, creating animal and plant crossings, nurturing ecosystem services such as carbon
fixation and water quality improvement, and promoting outdoor recreation and the prevention
of floods and landslides.
At the Campus level, the proposal is built upon four pillars: the Articulation System, which
solves connectivity issues between the University and its environment considering mobility factors; the Border System, which analyzes the relationship with the context, adding defined
accesses and cushioning fringes; the Functional Units System, which groups homogeneous
elements with defined identities; and finally, the Conservation and Ecology System, which
promotes ecological and landscape connectivity through two components: water and
vegetation. Green infrastructure acts as a natural public health system, favoring physical
activity, establishing a bridge that unites forest patches and boosts ecosystem services
responsible for preventing climate change. In order to mitigate flooding, there is a chain of
lagoons in which water moves by gravity, accompanied by canals and rain gardens that delay
water speed, improve its quality and enriches the user experience.||es
