SANTA CATARINA RIVERFRONT REDEVELOPMENT MONTERREY, MEXICO

T

he proposal of Santa Catarina Riverfront development aims to bring the north and the south bank of the city together through the creation of an active, green and accessible riverfront and riverbed design. The proposal integrates storm water management, flood mitigation and place for active recreation for the city of Monterrey.

We propose sinking the highway which currently banks the river edge and create accessibility barrier for the city dwellers. By sinking the highway, we have created a wide riverfront promenade connecting the city streets along with the riverbanks. The riverbanks have been stabilized to mitigate consistent erosion and have been provided with flood cisterns beneath them.

The flood cisterns stores water and helps in draining the increased water level in rive bed rather than draining it out. This improves local ecology and hydrology. On the top of cisterns, we have provided levels of recreational space which depending on the severity of floods still remain open to public usage.

This major strategy has been complemented by numerous other studies regarding local flora and fauna, newly available real estate in proximity to the river and improved accessibility on the riverfront to make it socially inclusive, culturally appropriate and environmentally sustainable place in Monterrey.

AUSTIN’S WALKABILITY DATA STORY AUSTIN, TEXAS

O

ver the past two decades, planning discourse has identified multi-modal transportation as one of the key areas to further environmentally sustainable and socially equitable urban development.the virtue of walkable places and accessible public transit, as demonstrated by Denver, San Diego and Washington D.C., has proved to most effective planning tools to migrate from low density, auto-centric sprawling suburbs to sustainable and thriving urbanity. Austin has followed the league by committing to improve its transit service with special emphasis on integrating non-motorized forms of travel like walking and biking.

In order to gain a better understanding of the walkability ecosystem in Austin, this GIS study maps relationship between these travel patterns and spatial characteristics like density, diversity and design (3-D variables) within the City Limits. The study then progresses to explore the relationship between Walkability Index and household travel characteristics of built environment. As discussed earlier, the interdependency between urban vehicular mobility, morphology and household travel pattern indicators has been well studied. I intend to add to this body of knowledge from non-vehicular perspective for Austin City Limits through Geographically Weighted Regression (GWR). The study inquires whether walkability in Austin has any significant relationship with indicators of household travel consumption such as CO2 emissions per HH, transit ridership % of workers, vehicle ownership and destination accessibility.

Multi-modal integration in Austin.
