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 />
