Background
• In the 1930’s and 1940’s, the USIBWC constructed the Rio Grande Canalization Project (RGCP) as a water delivery and flood control project.
Background
• The RGCP stretches for 106 river miles from Percha Dam, NM to American Dam in El Paso.
Background
• In 2009, the American Recovery and Reinvestment Act (ARRA) allocated funds to the USIBWC for the rehabilitation of levees.
• Portions of the ARRA funds have gone towards the rehabilitation of the RGCP in order to meet FEMA levee accreditation standards.
RGCP Levee Rehabilitation• Several levee segments along the RGCP have already been
rehabilitated and submitted to FEMA for levee accreditation, including the west levee within the Vinton and Canutillo area.
RGCP Levee Rehabilitation• Several levee segments along the RGCP have already been
rehabilitated and submitted to FEMA for levee accreditation, including the west levee within the Vinton and Canutillo area.
RGCP Levee Rehabilitation• Several levee segments along the RGCP have already been
rehabilitated and submitted to FEMA for levee accreditation, including the west levee within the Vinton and Canutillo area.
RGCP Levee Rehabilitation• The east levee along this reach is pending rehabilitation and
the USIBWC has begun to move forward with this project, also known as Canutillo Phase II.
Purpose
• The purpose of the Canutillo Phase II project is to improve the east levee of the river in order to protect the adjacent properties against flooding from the river.
• The improvements must meet 44 CFR 65.10 regulations for the levee to be accredited by FEMA.
• A FEMA-accredited levee removes the flood zone designation from the landside areas.
