2.1 Watersheds
The Town contributes stormwater runoff to three receiving streams and their
associated watersheds. Runoff from the Town primarily enters either the Grants Creek
or Cold Water Creek watersheds. A very small portion enters the Town Creek
watershed. Between Grants Creek and Cold Water Creek, approximately two thirds of
the Town's runoff enters the Grants Creek watershed and the other one third enters the
Cold Water Creek watershed. Figure 1 in Appendix A illustrates the boundaries of the
Grants Creek and Cold Water Creek watersheds and their major sub -catchments,
relative to the Town's municipal and ETJ boundaries. Another watershed overview
map, at a scale of 1"=1500' and including contours, is included in Appendix N.
2.2 Receiving Streams - Detailed Listina
The tributary streams are listed in the order in which they occur beginning at the most
downstream point of the named Creek within the program area and proceeding
upstream. The direction of flow of Grants Creek and Town Creek is from south to
north. Cold Water Creek flows from the north to the south. The "E" and "W"
designations indicate that the tributary is located to either the east or the west side of
the main creek. The numerical designation indicates the order of occurrence from the
�. most far point in the program area downstream to most upstream point in the program
area. Figure 2 in Appendix A illustrates the receiving streams in the program area.
