Litter THE FALL, 2002 LITTER INDEX AND PHOTOMETRIC INDEX The Field Surveys: The Litter Index is conducted by driving slowly through 9 representative areas of Irving. Trained citizen volunteers and City staff note the overall visual appeal of multiple segments of each area using forms and scoring mandated by Keep America Beautiful. The Litter Index is a similar process using anonymous photography at various sites such as dumpsters, loading docks, vacant lots and street fronts. Information gathering is strictly statistical and address and names are not part of the process. Students from the Nimitz High School Junior Historians Club perform much of this work under adult supervision and thus make an invaluable annual contribution to the quality of life in Irving. Background: From 1992 to 2003, Irving’s population increased about 25%. The number of jobs/workers increased about 50%. This means more hands to litter, more construction sites, more cars to litter from, etc. Nonetheless, the collective efforts of KIB and Code Enforcement, changed attitudes by some businesses, and greater numbers of active neighborhood groups have all had a discernible positive effect.
