Both of these restudies (including hydrology and hydraulic modifications) <br />have been reviewed and approved by the Urban Drainage and Flood Control District (UDFCD) <br />and the Federal Emergency Management Agency (FEMA). This restudy project was jointly <br />funded by the UDFCD and the City of Boulder. You should also receive a letter from Boulder <br />County with a similar request since portions of these floodplains are within their jurisdiction. <br /> <br />Following your conversation late last week with Nancy Love (our consultant), you advised her <br />you would not need to be provided with the full set of hard copies of the Letter of Map Revision <br />(LOMR) submittal but would instead accept a CD containing the complete restudy, the updated <br />hydrology and hydraulics for both streams and the floodplain models and profiles. Therefore, <br />attached to this "Request for Floodplain Designation" please find a CD containing a pdf of the <br />report. the hydrology, hydraulics, HEC-RAS models (multi-profile) and the profiles. We are also <br />included a non-pdf, useable input HEC-RAS model should anyone request said document from <br />the CWCB in the future. <br /> <br />If you have any questions, please feel free to contact me directly or for technical questions <br />contact our consultant, David Love, P.E. at 303-673-9795 or email atdlove(iV.loveassociates.com. <br />It is our understanding that this Designation will be on the March 12-13,2007 CWCB Agenda. <br />Please let us know when the Designation has been completed. Thank you for your assistance in <br />this matter. <br />
