<br />. <br /> <br />. <br /> <br />Gunnison County Flood Plain Mapping <br />Scope of Work <br /> <br />Project Description <br /> <br />Gunnison County, in cooperation with the Colorado Department of Natural Resources <br />(Colorado Water Conservation Board) and the Army Corps of Engineers, is in the <br />process of refining flood plain mapping for a series of waterways in the upper Gunnison <br />River and upper Roaring Fork River drainages. The location and extent of each <br />drainage is depicted on Exhibit A. The project will occur in three phases: <br /> <br />1. Topographic Mapping consistent with Corp of Engineers standards; <br /> <br />2. Hydrology Analysis; <br /> <br />3. Hydraulic modeling of the 100 and 500 year flood plain for the drainages <br />depicted on Exhibit A. <br /> <br />The first phase is the subject of this Project <br /> <br />Project Requirements. <br /> <br />Digital product deliverables will include high-resolution Digital Elevation Models (OEMs), <br />2 foot contour data, planimetric feature data and high resolution orthorectified images <br />for the subject study area. <br /> <br />Provisions <br /> <br />1. The selected contractor shall provide all personnel and equipment required to <br />perform data collection and processing. Project boundaries defining the data <br />collection area will be supplied by Gunnison County in cooperation with the <br />contractor prior to the authorization of a contract and the commencing of <br />work. <br /> <br />2. Data will be referenced to a mutually agreed upon National Geodetic Survey <br />high order control stations or other accessible and acceptable control points <br />specified by Gunnison County before contract authorization. <br /> <br />3. Tile data will be monumented and capped to be consistent with section <br />corners, or some other form of control mutually agreed upon prior to <br />authorization of a contract to ensure that the data generated can be used with <br />existing Gunnison County GIS data. <br /> <br />APPENDIX 2 TO CONTRACT C150085 <br /> <br />Page I of3 <br />
