Neighborhood Environment Assessment in Olivette Park
This interactive map provides information about Olivette Park aggregated by block. The map is based upon fieldwork data and other publicly available databases. According to the year 2000 GIS parcel map, there are a total of 1250 parcels in Olivette Park, arranged in 60 city blocks. The number of parcels does not precisely agree with the current number of parcels because some parcels have been merged with one or more other parcels. Also occasionally, one parcel has been divided into two or more parcels. However, these changes over time do not significantly affect our analysis. Most of the parcels maintain original location and dimensions, with less than 5% parcels having been restructured. The changes in parcels only take place within one block. Therefore, these changes do not impact the aggregated information of each block. During the fieldwork survey conducted by Prof. Dearborn and her class of Arch 576 in the fall of 2009, we completed on-site evaluation for 412 parcels by walking around the neighborhood documenting conditions through visual assessment. The other 838 parcels were photographed and assessed from these images, as well as other available public databases. Using these data, we are able to provide the following information for each block:
1) Number of parcels;
These data are based upon the year 2000 GIS parcel map.
2) Percent vacant parcels, indicates the percentage of parcels with no structures;
3) Percent parcels with structures;
Information for 2) and 3) were derived from on-site survey or photographs and other publicly available data if on-site survey information is unavailable.
4) Overall structure condition and structure characteristics, including building type, building height, building width, building address and some other commentary information.
For the 838 parcels that were not assessed on site, the information of building type and height are judged from photographs; building width is available on the St. Clair County Interactive Parcel Map (http://www.co.st-clair.il.us/Departments/GIS/maps.htm).
Building addresses for all parcels were acquired from St. Clair County Interactive Parcel Map or online map (http://www.bing.com/maps/).
The names of some institutions or commercial buildings were provided if they were available from Google Search.
5) Overall block lawn condition, measured by the average score of this item in all parcels in one block;
6) Presence of refuse, measured by the average score of this item in all parcels in one block;
7) Security issue, measured by the average score of this item in all parcels in one block
8) Overall presence of graffiti;
Information of 5), 6), 7) and 8) were from on-site survey or photographs if on-site survey information is unavailable.
9) Block images for demonstration.
All images were taken from the fieldwork.
This project was partially funded by the Community Informatics Initiative 2009-10, and a grant from the University of Illinois Public Engagement Office 2010.
