Final Notice and Public Explanation of a Proposed Activity in a 100-Year Floodplain, 500 year Floodplain, and Wetland To: All interested Agencies, Groups and Individuals This is to give notice that the City of Norfolk, under part 58 has conducted an evaluation as required by Executive Order 11988 and 11990, in accordance with HUD regulations at 24 CFR 55.20 Subpart C, Procedures for Making Determinations on Floodplain Management and Wetlands Protection. The activity is funded under the Community Development Block Grant. The proposed 1,214 foot-long sidewalk and installation of three hydrodynamic separators construction project is located on the west side of Devonshire Road between Philpotts Road and Quail Street, and adjacent to Horton Circle, Norfolk, Virginia. The purpose of the hydrodynamic separators is to remove sediment and pollutants from stormwater runoff. The scope of work within the 100-year floodplain (Zone AE) and wetland ditch includes the installation of one hydrodynamic separator adjacent to the existing stormwater drop inlet on Devonshire Road between Quail Street and Horton Circle, affecting 75 sf of tidal wetland ditch within the 100-year floodplain. Ten (10) percent of the sidewalk and one hydrodynamic separator will be located within the 500-year floodplain. Work outside the floodplain includes installation of a third separator on Horton Circle, constructing the remainder of the 1,214 foot-long sidewalk on Devonshire Road and related work. The City of Norfolk has considered the following alternatives and mitigation measures to be taken to minimize adverse impacts and to restore and preserve natural and beneficial values: The project must take place in the wetlands because existing infrastructure and drainage restricts alternative siting alternatives. In addition, pollutant removal would be less effective if the project was moved to the opposite side of the road and non-existent if the project was eliminated. Installation of the hydrodynamic separator will disturb 75 sf of wetland but will provide beneficial values by preventing sedimentation and reducing pollutant load on the same wetland. All work will be conducted in accordance with Federal, State, and local wetland laws and regulations. The City of Norfolk has re-evaluated the alternatives to building in the floodplain and wetland and has determined that it has no practicable alternative. Environmental files that document compliance with steps 3 through 6 of Executive Order 11988 and 11990 are available for public inspection, review and copying upon request at the times and location identified in the last paragraph of this notice for receipt of comments. There are three primary purposes for this notice. First, people who may be affected by activities in floodplains and wetlands and those who have an interest in the protection of the natural environment should be given an opportunity to express their concerns and provide information about these areas. Second, an adequate public notice program can be an important public educational tool. The dissemination of information and request for public comment about floodplains and wetlands can facilitate and enhance Federal efforts to reduce the risks and impacts associated with the occupancy and modification of these special areas. Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplains and wetlands, it must inform those who may be put at greater or continued risk. Written comments must be received by the City of Norfolk at the following address on or before June 7, 2018: City of Norfolk, Department of Public Works, 810 Union Street, Rm 700, Norfolk, Virginia 23510 and 757-664-4779, Attention: Tom Stokes, Stokes Environmental Associates, Ltd. A full description of the project may also be reviewed from 8 a.m. to 5 p.m. at SEA, Ltd., 4101 Granby Street, Suite 404, Norfolk, Virginia 23504. Comments may also be submitted via email to Devonshiresidewalk@Gmail.com. VP 25671641A
