Washington Gulch bas its <br />confluence with Slate River immediately upstream of the north I"';p<a'ty line.

This river is currently mapped on Panel No. 080078 32SB in Gwmison County <br />and is shown as Zone A. Zone A is defined as approximate mapping and does not include any base <br />flood elevations or hydrology. Thc::efore, to prepare a detailed study, this analysis includes a <br />hydrologic analysis and a hydrclulic analysis to establish the base flood elevations and better define <br />the floodplain boundary. This infonnation is required to help establish the limits of developmalt <br />which include a 20-foot setback from the floodplain limits in accordance with the Town of Crested <br />Butte's floodplain regulations. <br /> <br />Hydrology <br /> <br />Flood flow ~im_.. were made by statistical analysis of the USGS stream gage (D1uuber <br />091l1'SOO Slate River near Crested Butte) located on the north end of the project site.
