  • FC5.02 Tanque Verde Creek Lakes of Castle Rock Erosion Protection

    Total Actual Cost: $ 194,289
    Project Number: CFC5UBDRC
    Funding Sources: 2004 General Obligation Bonds
    Completion Date: June, 2011
    Managing Dept.: Regional Flood Control District
    Project Map: GIS Map

    The project provided improvements to restore the bank and prevent erosion at Common Area of the Lakes of Castle Rock. The improvements involved installing five weirs constructed of over 600 lineal feet of gabions. The project also diverted the deepest part of the flow away from the north bank. By diverting the flow, the project protects the Castle Rock property and the property immediately downstream owned by Pima County and used by Therapeutic Riding of Tucson (TROT), a non-profit organization. The project worked in tandem with bank protection installed this past spring at TROT to prevent erosion along the north bank at both properties. The project also preserved a large tree that was at least 50 years old and provided habitat for birds of prey.
