• Stop the illicit discharge or remove the illicit connection.<br />
10. Other Actions<br />
Additional actions were identified based on comments provided on<br />
the field forms. The problems and their associated actions are<br />
summarized in Table 3-2.<br />

Data Extrapolation<br />
The results of the data analysis may be extrapolated to the rest of the<br />
watershed as a means of estimating the magnitude of problems through the<br />
watershed. Road-stream inventories were completed at approximately 43<br />
percent (75 out of 173) of the crossings in the watershed. Table 3-3 estimates<br />
the total number of problems throughout the watershed based on direct<br />
proportions.<br />

Upland Field Assessment<br />
Field work was conducted by Tetra Tech Staff on July 19, 2005. Field<br />
methods used for conducting the upland field assessment were developed<br />
by the Center for <strong>Watershed</strong> Protection. A number of assessments were<br />
conducted to find potential problem areas, including Neighborhood Source<br />
Assessment, Pervious Area Assessment, Hotspot Assessment, and Streets<br />
and Storm Drain Assessment. These assessments were used to develop a list<br />
of potential solutions and retrofit projects that could lessen the impact of<br />
development and urbanization of the water quality of the <strong>Looking</strong> <strong>Glass</strong><br />
<strong>River</strong> <strong>Watershed</strong>.<br />
