2 Street, and the cross-section letter designation at 1 04thA venue was corrected. The modifications are shown on the enclosed annotated copies of FIRM Panel(s) 0800lC0038 G; ProfilePanel(s) 125P, 129P, and l31P; and affected portions of the Floodway Data Table. Profile Panel l30Pwas deleted from the FIS report. This LOMR hereby revises the above-referenced panel(s) of the effective FIRM and the affected portions of the FIS report, both dated August 16, 1995. Our review of the submitted data revealed that the BFEs increased as a result of the construction of Bannock Street and the culvert that crosses under it. Because the BFEs increased as a result of construction in the regulatory floodway, the City of Northglenn is potentially in violation of its floodplain management ordinances and Section 60.3( d)(3) of the NFIP regulations that prohibits encroachments, including fill, new construction, substantial improvements, and other development within the adopted regulatory floodway unless it has been demonstrated through hydrologic and hydraulic analyses performed in accordance with standard engineering practice that the proposed encroachment would not result in any increase in flood levels within the community during the base flood. We have notified our Regional Office in Denver, Colorado, of the potential floodway violation. Because this revision request also affects the City of Thornton, a separate LOMR for that community was issued on the same date as this LOMR. The following table is a partial listing of existing and modified BFEs: Location Existing BFE (feet)* Modified BFE (feet)* Just upstream ofl-25 Approximately 700 feet downstream of Melody Drive Approximately 150 feet downstream of Melody Drive 5,368 5,372 5,385 5,366 5,375 5,384 *Referenced to the National Geodetic Vertical Datum, rounded to the nearest whole foot Public notification of the proposed modified BFEs will be given in the Northglenn-Thornton Sentinel on or about May 18 and May 25,2000. A copy of this notification is enclosed. In addition, anotice of changes will be published in the Federal Register. Within 90 days of the second publication in the Northglenn- Thornton Sentinel, a citizen may request that FEMA reconsider the determination made by this LOMR. Any request for reconsideration must be based on scientific or technical data. All interested parties are on notice that, until the 90-day period elapses, the determination to modifY the BFEs presented in this LOMR may itself be modified. The modifications made by this LOMR will become effective after the 90-day period has elapsed. The map panel(s) as listed above and as modified by this letter will be used for all flood insurance policies and renewals issued for your community. Because this LOMR will not be printed and distributed to primary users, such as local insurance agents and mortgage lenders, your community will serve as a repository for these new data. We encourage you to disseminate the information reflected by this LOMR throughout the community, so that interested persons, such as property owners, local insurance agents, and mortgage lenders, may benefit from the information. We also encourage you to prepare a related article for publication in your community's local newspaper. This article should describe the assistancethat officials of your community will give to interested persons by providing these data and interpreting the NFIP maps. We will not physically revise and republish the FIRM and FIS report for your community to reflect the modifications made by this LOMR at this time.
