Murrieta Creek

Murrieta hero

Overview

Location: Temecula, CA

Project Type: Shorelines & Waterways

Application: Arid & Channel Stabilization

Project Used: ARMORMAX

Problem

On October 27, 2000, the Energy and Water Development Appropriations Act of 2001 was signed into law, which directed the USACE to proceed with detailed engineering designs for the Murrieta Creek Flood Control, Environmental Restoration and Recreation Project. Historically, the cities of Murrieta and Temecula had experienced devastating flooding along Murrieta Creek. The purpose of this project was to prevent such flooding by conveying the 100-year flow within Murrieta Creek.

Solution

ARMORMAX was selected to provide erosion and scour protection on the creek banks. The system consists of High Performance Turf Reinforcement Mat (HPTRM) and earth anchors that provide resilient flood control for up to 75 years. Maintaining water quality was a main concern because Murrieta Creek is recognized as one of the last high quality minimally disturbed riverine environments in Southern California.

Performance

ARMORMAX helped to decrease sedimentation and pollutants and encourages infiltration of water back into the ground water table. The system also promotes rapid root development for long-term vegetation, whereas rock riprap, can decrease streamside vegetation and adversely impact fish populations. Vegetation quickly established and the EEAS has effectively protected against erosion and flooding.
