Towards the city center, there is a more formal organization of park spaces, aligning with axes that are defined by roads and the built environment. These pockets create, both formally and informally, nodes of public space. Moving away from the city center, the spatial organization of parks change as well as their public perception, particularly along the Najafgarh Drain.

Informal parks along the drain are commonly used for household activities and trash. They are found between buildings in empty lots. One typology is found in vacant lots, or areas of urban decay. They are utilized without specific intention.

The second informal typology uses open space in urban areas for communal public services, such as water access, parking and storage, and more practical needs such as open spaces to hang laundry.
