Re: Bronx River Greenway
The purpose of this memo is to discuss the details surrounding the research of the Bronx River Watershed
populations demographic to determine the necessity for bilingual signage in the Bronx River Greenway.
This memo is concerned with the details of that report.
Proposal for Bilngual Signage
After careful research and analysis of the Bronx River Watershed study area, it has become apparent that
it would be most advantageous to the alliance to move forward with its proposal to institute bilingual
signage along the Bronx River Greenway. To support this proposal, statistical data from both the 2000 US
Census and the NYC Department of Planning was collected and mapped using ArcGIS to provide a clear
picture of the population’s demographic within the Bronx Watershed area. This data is displayed in a
sequence of maps by census track and block groups. In Figure 1, well over 50% of the population that
speak a language other than English are concentrated along the river according to the 2000 US Census
Bureau. These results are shown according to census block. Once data was mapped, we then mapped
the percentage of the total population of within the watershed area that spoke Spanish (Figure 2,) where
they are located in their highest concentration by block group, and how well they spoke English (Figures
3-5). Compared figure 1, the percentage of the total population who speak Spanish (from 5yrs old and up)
are mostly concentrated along the river. The largest percentage of this population is concentrated along
the Sheridan expressway (figure 3) and represent at least 80% or more of the total population of the
watershed area. The images are attached to this memo.
