2.2.4 Stream Flow
A watershed will generate larger volumes of storm water runoff and discharge this runoff
at higher rates as the amount of imperviousness increases as a result of development. The
stream channels that receive the additional runoff are exposed to increased hydraulic
forces that can lead to morphologic instabilities through erosion – a process that reduces
the availability and quality of aquatic habitat. Aquatic species are dependent upon the
channel boundary for shelter, foraging, reproduction, and rest. When boundary materials
regularly erode, the aquatic habitat is impacted and unlikely to support a diverse, healthy
aquatic community. Therefore, addressing the source of the habitat degradation,
additional storm water runoff in this case, will help reduce impairment to in-stream
biological communities (Tetra Tech, 2004)
2.2.5 Land Use/Land Cover
The land-use/land-cover data set used for this Watershed Management Plan was
developed by Tetra Tech Inc. (2004) for the Post Construction Ordinance development
process. The data set was developed through interpretation of a combination of parcel
information, aerial photographs, and tree canopy data. The process is more thoroughly
described in Tetra Tech Inc. (2004). The land-use data set provides a distribution and
classification of all land-uses in the Goose Creek Watershed. The land-use categories
represented in the Goose Creek Watershed are presented in Table 6 and the distribution
of the land-uses for the Goose Creek Watershed is shown in Figure 8.
