Rio Rancho Sportsplex Erosion Control Project Final public notice
FINAL PUBLIC NOTICE
Executive Order 11988: Floodplain Management
Public Notice is hereby given that the Federal Emergency Management Agency (FEMA) intends to provide assistance to the City of Rio Rancho via the State of New Mexico Department of Homeland Security & Emergency Management through its Hazard Mitigation Grant program for the Rio Rancho Sportsplex Erosion Control project that will provide arroyo bank stabilization by constructing bank/slope paving along approximately 1,500 linear feet of the south side of the arroyo located at 3501 High Resort Blvd. SE in Rio Rancho, New Mexico.
A map of the Rio Rancho Sportsplex Erosion Control project may be viewed by clicking here. Additionally, a map is also available for public inspection at Rio Rancho City Hall, 3200 Civic Center Circle NE, Suite 100, Parks, Recreation and Community Services Department. Parties interested in inspecting a map in person may also call the Parks, Recreation and Community Services Department at 505-891-5015, or Dyane N. Sonier, Resource Development Manager at 505-896-8728 for information.
FEMA has determined that the proposed action is located within the regulatory floodplain, traversing FIRM panels 35043C1893D and 35043C1894D. Presidential Executive Orders 11988 (Floodplain Management), as implemented in 44 Code of Federal Regulations (CFR), Part 9, require that certain federal actions in or affecting the floodplain or wetlands be reviewed to determine if there are any practicable alternatives outside of the floodplain or wetland; to identify and minimize impacts; and to provide initial and final notification to the public regarding its actions in the floodplain or wetlands. Initial public notice has already been achieved for this project either through a disaster-specific cumulative notice or a project specific individual notice. Any comments and other information received were fully evaluated by FEMA along with evaluation of social, economic, environmental, and safety considerations. This notice constitutes final public notice as required by 44 CFR Part 9.12.
The proposed action as described above must be located in an area affecting or affected by a floodplain or a wetland because it is the only practicable alternative that will achieve the purpose and need for the project. The Rio Rancho Sportsplex Erosion Control project is located along the Arroyo de Los Montoyas which has eroded significantly over multiple past flood events that required repeated replacement of the eroded bank to ensure a safe environment for the patrons using the Rio Rancho Sports Complex. Bank stabilization and erosion control are needed to protect the sports complex and its patrons from future erosion. Alternatives considered by the City included not completing the project, which would leave the facility and citizens at risk; installing bendway wiers to divert flash flood flows to the center of the arroyo, which were considered unproven for ephemeral streams (arroyos) and unable to provide sufficient flood protection; and the proposed action of constructing approximately 1,500 linear feet of non-structural slope paving applied directly to a filled 2:1 slope, extending from an average of 8’-8” below the invert of the arroyo to a height of 10’ above the invert of the arroyo and tied to existing concrete structures. The proposed action will be performed in compliance with the National Flood Insurance Program and will conform to applicable state and local floodplain protection standards. The proposed Rio Rancho Sportsplex Erosion Control project will reduce any detrimental downstream effects in that there will be less sediment deposited at the Hwy 528 crossing and the Harvey Jones channel in the Village of Corrales. Hydraulic Analysis Documents for this project indicate there will be no appreciable effects on the water surface elevations or Base Flood Elevations through the project area or areas upstream or downstream of the project, and the proposed project does not include any components that will cause any constriction and thus allows for the pre-existing flows. Further information regarding this project can be obtained from the City of Rio Rancho Public Works Department, Arnell Friedt, Project Manager (505)896-8242, firstname.lastname@example.org; and the Parks Recreation and Community Services Department, Dyane Sonier, Resource Development Manager (505)896-8728, email@example.com .
