Non-Reimbursable Application-CWCB Construction Fund <br /> Form Revised August 2004 <br /> • <br /> 3. Provide a brief description of your organization below: <br /> The Flood Protection Program, one of five work sections of the CWCB, has evolved over time <br /> and expanded its operations to include numerous flood-related activities that assist in the <br /> prevention of loss of life and damage to property caused by flooding events. The CWCB is <br /> authorized by Statute to perform such activities. <br /> Tart B.-Description of the Project or Study <br /> 1. Name of the study or project: NOAA Atlas 2 Precipation Atlas Update <br /> 2. What is the purpose of this grant application? Check one. <br /> xx Study <br /> Demonstration project. This request is to provide funds for the purpose of updating the long <br /> Rehabilitation or out-of-date NOAA Atlas 2 for the State of Colorado. This document <br /> identifies point precipitation values for various durations and return Ank <br /> • <br /> replacement of existing frequencies for all points in Colorado. The National Oceanic and up <br /> Other(Please describe) Atmospheric Administration is updating this document in groups of <br /> states with significant state cost shares. <br /> 3. General location of the study or demonstration project. (Please include county, and approximate distance <br /> and direction from the nearest town): <br /> This study will cover Colorado and six adjacent Midwestern states. Funds requested under this <br /> application will only be used to pay for work affecting Colorado. Precipiation data for the entire <br /> State of Colorado will be updated with this request. Therefore,the location of this project is the <br /> entire State of Colorado. <br /> 4. Please provide a brief narrative description of the proposed study or demonstration project including <br /> purpose,need, and service area. (Attach scope of study,if available) <br /> The NOAA Atlas 2 is the only document that provides point precipitation values for various durations <br /> and frequencies throughout the State of Colorado. This precipitation information is crucial to the <br /> development of engineering projects and the design of hydraulic structures including bridges,culverts, <br /> channels, levees,etc. In addition,this point precipitation value is a key input in the delineation of <br /> floodplains in all areas of the state. <br /> The current NOAA Atlas is 35 years old,and this update will nearly triple the period of record inherent <br /> in the results. As such,the accuracy of the data will be much improved,thereby mitigating the <br /> occurrences of over-or under-design of hydraulic structures or inaccurate floodplain delineations. <br /> 2 <br />
