<br />lO.O REVISIONS DESCRIPTION <br /> <br />oi,." <br /> <br />This section has been added to provide information regarding <br />significant revisions made since the original Flood Insurance Study was <br />printed. Future revisions may be made that do not result in the <br />republishing of the Flood Insurance Study report. To assure that any <br />user is aware of all revisions, it is advisable to contact the <br />community repository of flood hazard data located at city Hall, 20120 <br />E. Main Street, Parker, Colorado 80134. <br /> <br />lO.l First Revision <br /> <br />This study was revised on July 4, 19B9 to reflect the effects of <br />the new State Highway 83 (Parker Road) Bridge across Sulphur Gulch <br />and overlot grading for property identified as Parker Central Area <br />C-l2 property. As a result of these changes, the floodplain and <br />floodway were redefined fOr a reach of Sulphur Gulch from Pikes <br />Peak Road to a point approximately 1,200 feet downstream. The <br />revised hydraulic analysis for this reach was developed by Greiner <br />Engineering Sciences, Inc., Denver, Colorado, and presented in <br />their technical report, entitled "Sulphur Gulch Letter of Map <br />Revision, Parker General Area C-12, Parker, Colorado," dated August <br />1987. Profile Panels 08P and 09P and the floodway data table for <br />Sulphur Gulch have also been revised. <br /> <br />New approximate Zone A flooding was added to Tallman Gulch <br />Tributary from its confluence with Tallman Gulch to a point <br />approximately 2,800 feet upstream. The basis for this revision is <br />a technical report, entitled "Flood Hazard Identification Report, <br />Tallman Gulch Tributary 1, Parker, Colorado," prepared by the <br />Department of Natural Resources, Colorado Water Conservation Board, <br />and dated December 1986. This report included the hydrologic and <br />hydraulic analyses for this reach of Tallman Gulch Tributary. <br /> <br />This study also incorporates a Letter of Map Amendment issued on <br />October l2, 1987, for the Saddlebrook Subdivision l;'iling Number 1 <br />located along Sulphur Gulch. In this letter, Lots 85 through 88, <br />Block 1, and Lots 22 and 23, Block 2, were identified as no longer <br />within the Special Flood Hazard Area, Zone AE, due to the placement <br />of fill. These lots are now located in Zone X. The revised <br />floodplain delineation is reflected on FIRM Panel 0090. <br /> <br />19 <br />
